Datang Institute of Technology

After Xu Changsheng settled Pei Ju, he and Pei Xingjian returned to Chang'an.

Along the way, Pei Xingjian sighed, "Xu Jiazi, your college is too good, it's like the residence of the gods, I'm a little reluctant to leave."

Xu Changsheng smiled, "If you don't mind being frugal, you can give up being an official and come to teach in our academy."

Anyway, his academy still has to recruit some children, and the children in Xujia Village also need to go to school. If Pei Xingjian can come, he will welcome him with both hands.

Pei Xingjian: "..."

Do you think everyone is as free and easy as Xu Jiazi, can give up fame and wealth, and hide in the mountains?

Thinking of this, I sighed even more, "Hey, frugality is a layman after all."

Maybe only someone like his grandfather is qualified to teach in such a fairyland.

After Xu Changsheng bid farewell to Pei Xingjian, he returned to the Prince's Mansion and continued to study papermaking with Erdan and the others.

The movable type made of mud has been transported back to Xujia Village to be fired. According to the uncle's reply, the fired movable type can be used. Now the printing factory is preparing to discard the engraving block and use movable type instead.

After all, Datang Metropolis Daily has an edition every seven days, and every time it uses engraving, it is very troublesome.

After movable type printing became popular in printing factories, it was time for Xu Changsheng to start building the strongest library for his academy.

This matter has to be helped by grandpa and Mr. Pei.

There are countless books in the Great Tang Dynasty. Although Xu Changsheng said that he wanted his library to contain all the books of the Great Tang Dynasty and the works of sages, there must be a priority.

The great grandfather and the others are needed to help select which ones to print first and which ones to print later.

In the next few days, Xu Changsheng didn't go out much.

He has been studying papermaking all day long, and now Chang'an is spreading his papermaking reforms, and even many scholars come to the East Palace to inquire whether it is true or not.

Today's East Palace gate is full of traffic and crowded, if it is not opened sooner, it will not be a disappointment to everyone's enthusiasm.

Xu Changsheng sighed a little.

Erdan was stunned for a moment, "Changsheng, haven't we made better paper again? Why are you sighing?"

Xu Changsheng said, "It's not about papermaking. I'm thinking about the college recruiting teachers. It's been so long, and the teachers haven't recruited enough."

Erdan showed a shy expression when he heard that, "Actually... Actually, I can teach grafting and cooking, I'm very good at it."

Xu Changsheng: "..."

He couldn't help shivering. It's reasonable for Erdan to teach cooking, but it's a pity that there is no such course, but grafting?

Thinking about the strange tree in a college, Xu Changsheng couldn't help but shudder. Now that strange tree in the college is enough to make people thrilling. Does Erdan want his college's demons to dance around?

too frightening.

There was a wordless chat.

Xu Changsheng watched the newly made paper pattern, which seemed to be of much better quality than the ordinary paper last time.

In this way, he already has three grades of paper.

The first is rough paper for wiping butts, the second is ordinary paper that can be written on, and the third is the current, snow-white paper with a very good texture, and you don't have to worry about staining when you write with a brush.

Three kinds of quality paper are enough for the daily use of different classes. He is taking the route of popularization and benefiting the country and the people. It is difficult to produce that kind of luxury quality paper.

Xu Changsheng heaved a sigh of relief, and looked at his small notebook, which recorded all the experimental processes, especially the successful records, which were marked in black.

Said, "Erdan, you don't need to boil the pulp anymore."

Erdan was pleasantly surprised, the cooking pulp didn't smell good at all, and it wasn't as fun as his cooking.

Xu Changsheng sorted out the records, sent them back to Xujia Village, and asked the Xu family to follow his records and experiment, and when the process was stable, they began to build the paper mill.

The manpower in Xujia Village has been insufficient for a long time, and now the factories are basically hired from outside the village.

Most people in Xujia Village work as supervisors and technical guides in the factory.

The factories are all designed according to the assembly line operation, and different people complete different processes, which prevents the process from outflowing.

Even if others gathered all the workers on the assembly line, it would be impossible to copy the products of Xujia Village.

Because the most core and last process is always in the hands of Xu Jiacun, without this core process, the things produced are specious.

In the paper mill, Xu Changsheng also plans to do the same. There are a group of people who collect materials, a group of people who boil the pulp, a group of people who bake the vats, and a group of people who make paper, etc.

The people of each craft do not use the same village, so as to avoid them communicating with each other and linking crafts to the greatest extent.

Xu Changsheng wrote down everything he was going to explain in the letter, and had someone send it to Xujia Village.

Then went out.

Er Dan also wandered behind, he had been in Chang'an for so long and didn't go out much, because he was afraid of getting lost, so he happened to follow for a stroll now.

Brother Changbai was left in Ronghua Palace to study.

Chang'an is much more prosperous now than it was more than ten years ago.

Xu Changsheng and Erdan had an interesting time shopping.

In particular, Erdan is curious about everything, there are many gadgets that Xujiacun can't buy.

It didn't take long for Erdan to hold a lot of messy little things in his arms.

The small vendors along the way also noticed that there seemed to be endless money in the pocket of this little round face.

The corners of Xu Changsheng's mouth twitched. What weird things did you buy?

But Er Dan likes it, so let him do it.

Erdan was very happy, he likes to go shopping with Changsheng.

However, suddenly there was the sound of galloping horses.

Some people are riding horses, and there are many people.

Erdan was so frightened that he dropped everything in his hands. When he was in Xujia Village, the traffic rules were very clear. He had never encountered such a situation. How could a horse charge at a person? He was a little dumbfounded for a while, what? Condition

Xu Changsheng quickly pulled a handful of bastards.

A group of people on horseback drove up quickly, and they were all soldiers wearing Tang Mingguang armor.

The horse's hooves flew past Xu Changsheng and the others, trampling Erdan's things on the ground to pieces.

Er Dan was dumbfounded, he bought it just now, but he hasn't played it yet.

Xu Changsheng's attention was still on the group of horse riders.

Because he actually knew the leader.

Some doubts, because the person who took the lead was actually Li Junxian.

Li Junxian, as the commander of the imperial palace guards, is different from the dudes in Chang'an. How could he ride his horse in Chang'an in broad daylight?

Er Dan was picking up things on the ground with an unhappy expression on his face, many of them were unusable.

Xu Changsheng was still looking at the group of people whizzing by, because they stopped not far away, outside a medical clinic.

Xu Changsheng said to Er Dan, "Let's go and have a look."

Erdan nodded, and told them to pay compensation in the past. They didn't understand the rules like they did in Xujia Village. Riding a horse in Xujia Village would be restricted from entering Xujia Village forever.

Erdan followed Xu Chang angrily and walked towards the medical hall.

As soon as he got close, Xu Changsheng realized something was wrong.

There was a soldier wearing Mingguang armor lying on the ground. His body was bleeding all over the place. There were knife wounds on his body, and the wounds were already white. This is a phenomenon of excessive blood loss.

Perhaps due to excessive blood loss, the soldier's face was pale and his spirit was blurred.

Xu Changsheng thought to himself, he must stop the bleeding immediately, otherwise he would not be able to live if he lost the blood.

Li Junxian was being treated by the doctors in the medical center, and then he cupped his hands around, "Human life is at stake, how much I offended you just now."

Erdan showed a head from behind Xu Changsheng, "So it was to save someone, Erdan forgives you, this person on the ground is really miserable."

The doctor was also carefully examining the wound and applying the best medicine, but the wound was too big and the bleeding could not be stopped at all.

The doctor's expression was not very good, and he said to Li Junxian, "The wound is too big, I'm afraid..."

He has tried his best, but with this kind of injury, he can't recover.

Li Junxian's complexion is not good anymore, he had a glimmer of hope at first, this doctor is one of the best in Chang'an.

Kneeling down and looking at the soldier, he said, "I will take care of your family, and I will also take credit for your Majesty."

The soldier's mind was blurred, and when he heard Li Junxian's voice, he came back to his senses, showed a miserable smile, and said thank you in a weak voice.

He knew he was going to die, and he knew it on the way, because he had not seen anyone who could be saved because of such a serious injury.

If he could get a guarantee from Commander Li before he died, he would die without regrets, but he felt sorry for the orphans and widows at home.

Some are not reconciled, but can't help but accept the reality.

The people in Chang'an who were watching the bustle around probably also noticed that the soldier and he might have been seriously injured while performing the mission.

There was sadness in his eyes.

Although their Great Tang was intimidating everywhere, there were always some reckless guys who watched them secretly like wolves, and wanted to tear off a piece of flesh whenever they had the opportunity.

"Get ready for the funeral," said the doctor.

Li Junxian also reached out to hug the soldier.

But suddenly, a voice like Wen Yu sounded, "Wait."

Xu Changsheng thought to himself, if he moved violently, the soldier would really be hopeless.

Li Junxian frowned, looked at Xu Changsheng who was taking a step forward, and looked at this gentle and jade-like young man, his eyes shrank suddenly. Although he hadn't been in Chang'an recently and hadn't received any news about Chang'an, his first He immediately saw the white jade flute on Xu Changsheng's waist.

Xu Changsheng said, "Uncle, if you don't want your soldier to die, quickly put him on the ground."

Big...uncle?

Li Junxian was taken aback for a moment, but he glanced at Xu Changsheng's surprisingly tender face, and thought that the uncle should be the uncle.

Quickly put the man on the ground and said, "Xu Jiazi, can you save him?"

Xu Changsheng shook his head, "Not necessarily, but you can try. It's better than letting him wait to die. You should treat him like a dead horse and a living horse doctor."

Xu Changsheng really couldn't guarantee it, because he was not a doctor after all, so he had to prepare his way out first, and said, "Whether you let me save you or not, it's up to you."

Li Junxian: "..."

Everyone around was stunned.

When will Xu Jiazi know how to be a doctor?

At this time, someone suddenly said, "I have seen Xu Jiazi rescue a feverish and purple child outside the city of Chang'an. Everyone thought that the child would die, but Xu Jiazi stabbed it with a needle a few times. It came back to life, which is amazing."

Xu Changsheng: "..."

What is chaotic?

Li Junxian said, "Xu Jiazi act quickly, no matter life or death, I will explain it for you."

This is going to be involved in a life lawsuit. Although there will be nothing wrong with the prince behind the Xu family, it will probably be very troublesome. It will be different if he explains it.

Xu Changsheng nodded, now is not the time to talk about this, the people on the ground are still bleeding.

The doctor opened his mouth, how could such a serious injury be saved?

But in the end, he didn't say anything, just as Xu Jiazi said, treat a dead horse as a living horse, after all, there will be a glimmer of life, although in his opinion, this life is minimal.

Xu Changsheng asked the doctor directly, "Is there any needles, thread and spirits in the medical hall?"

The doctor said, "There are gold needles for acupuncture, and I'll bring them for you."

Xu Changsheng shook his head, "What I want are embroidery needles for embroidery."

The doctor is confused, is this healing or embroidery?

Xu Changsheng thought to himself, what's the use of golden needles?

Gold needles have no holes for threading.

The doctor gritted his teeth, "Embroidery needles and threads are also available, but you have to go to the liquor store to buy spirits."

Li Junxian interjected, "I have spirits right here."

The two quickly prepared the things and brought them over.

But I was very puzzled in my heart, how can I use embroidery needles and threads to treat diseases, and why do I need strong wine?

Xu Changsheng soaked the threaded embroidery needle and thread in spirits.

Even the doctor can't understand it, why?

The thread is hemp thread, which is actually not particularly suitable for suturing wounds, but it doesn't matter so much now, and the bleeding must be stopped first.

Xu Changsheng glanced at the soldier, at least he hadn't gone into shock due to blood loss, that is to say, the amount of blood loss hadn't reached the threshold.

After a while, Xu Changsheng picked up the needle and thread.

But the situation arises.

He has never done this before, and even the flowers have never rusted.

Moreover, looking at the cracked white meat, he really couldn't do it.

Gritting his teeth, he looked at the doctor who was staring at him beside him, leaned into his ear and said, "Come here, so..."

The doctor was stunned, "Isn't this treating him like a piece of rag, like embroidery?"

Xu Changsheng nodded, "I have never been a doctor, and my hands are unstable."

doctor:"……"

Xu Changsheng said, "Don't worry, no one will blame you if the doctor dies, everyone will watch what happens."

After thinking for a while, he said, "This is my peerless medical skill. As long as you dare to do it, you can use this medical skill casually in the future."

As soon as the doctor gritted his teeth, Xu Jiazi was right. Datang is a reasonable place. In this case, no one would blame him for treating people to death. What's more, Xu Jiazi said that this is a peerless medical skill. How amazing Xu Jiazi is, as an old man in Chang'an , better than anyone else.

He took the needle and began to sew, with Xu Changsheng guiding him.

The onlookers were stunned.

"This... what kind of medical skill is this?"

"Sew people like a rag bag with embroidery needles?"

This medical skill looks shocking enough.

Even Li Junxian shuddered. This is threading a needle through a human body. No wonder Xu Jiazi couldn’t do it. Imagine a polite and polite young man using a needle to mend a human body. The picture is quite terrifying. ...

Even the doctor's hands were trembling.

Xu Changsheng was very calm. After all, he was not the one who did it. He said from the side, "Don't panic. Although this medical skill is somewhat incomprehensible, Changsheng guarantees that it is indeed an astonishing medical skill."

In order to relieve the doctor's pressure, Xu Changsheng continued, "Doctor, you have been practicing medicine for many years, so you should often give people needles. Sometimes, after the needles are injected, the holes of the needles become thicker."

The doctor thought, it is indeed so, but this happens to some people, and it doesn't happen to some people.

Xu Changsheng continued, "This is due to infection. Did you see that I soaked the needles and threads in strong wine just now? You will also treat your golden needles for acupuncture in the future, so that the holes of the needles will not thicken."

Xu Changsheng spoke so clearly and logically in order to convince the doctor to believe him.

Sure enough, the doctor's hand stabilized a lot.

Xu Changsheng continued, "When a person suffers a small injury, the wound will heal automatically, because the flesh of the wound is very tightly attached and will automatically grow together. We sew the wound together in this way, even if the flesh is attached, it will also heal. grow together automatically."

The doctor's hands became more stable, and what he said was indeed reasonable.

It took many stitches to close the wound.

It's like a piece of cloth sewn together.

The soldier was about to faint at first, but now he couldn't pass out, looking at the hands sewing on his body.

He was stunned, what's going on?

He is not a piece of cloth?

But it doesn't seem to hurt either.

In fact, it was because the nerves in his wound were numb, and because he had lost too much blood, his sensory nerves were already extremely dull.

Seeing that the wound was stitched up, Xu Changsheng continued, "Now use your medicine to stop the bleeding."

The doctor hurriedly brought the medicine just now and sprinkled it on the wound.

After a while, the bleeding... stopped.

The doctor's eyes narrowed. Judging from his medical experience, as long as the bleeding stops, he can save this person.

His face was happy, he was going to be famous.

Hastily asked someone to lift a tablet out, "Carry him in."

This person has to recover in his clinic, even if Commander Li wants to take him away, he won't give it.

The doctor stroked his beard, "The patient is seriously injured and cannot move easily, so he should stay in the hospital first."

Xu Changsheng: "..."

This little old man is quite interesting.

This little old man is not bad, he is willing to give it a try even though he knows that he may not be able to save the living, the average person may rush him away, after all, the reputation of the medical clinic will be affected if the dead are treated.

Xu Changsheng saluted and asked, "I don't know the old man's name."

The doctor replied, "Old man Wang Tao."

Xu Changsheng: "..."

Wang Tao, a famous doctor in the Tang Dynasty?

I didn't expect to meet a famous doctor as soon as I went out.

That's right, to be able to sit in such a large medical clinic in Chang'an, the doctor must not be an ordinary person.

Wang Tao seemed to be particularly interested in Xu Changsheng, "I heard about Xu's family's excellent medical skills more than ten years ago, and seeing him today really deserves his reputation."

Xu Changsheng was stunned, why didn't he know that he had excellent medical skills?It was more than ten years ago.

Wang Tao said, "The old man's in-laws are in the south of the Yangtze River. Everyone in the south of the Yangtze River knows that Xu Jiazi's medical skills are superb. The big neck disease was caused by Xu Jiazi's single-handed efforts."

Xu Changsheng: "..."

It turned out to be this one.

Wang Tao continued, "The old man is very interested in Xu Jiazi's wound suturing technique and the use of spirits just now. I wonder if I can come in and have a chat?"

Li Junxian who was left out in the cold: "..."

How is his soldier, but someone should come out and tell him.

Xu Changsheng was welcomed into the hospital by Wang Tao.

As the chief sitting doctor here, Wang Tao is very respected.

Er Dan is extremely proud, have you seen that, their parents know everything, they are amazing.

Wang Tao checked the soldier's condition, and the soldier had already fallen asleep because his spirit suddenly relaxed.

Wang Tao felt his pulse. Although the pulse was weak, it was already very stable. As long as he could survive and wake up, he should be fine. Seeing that the soldier was in good physical condition, he might be able to survive.

Xu Changsheng also looked at it for a while, and said, "After his wound heals, he needs to take out the suture thread, otherwise it will become inflamed and thick."

After finishing speaking, he added, "Now it's best to feed him some sugar water to ensure that there is enough sugar in his body."

Wang Tao: "..."

Xu Jiazi seems to have a theory that has never appeared before.

Wang Tao's eyes lit up, "Come on, Xu Jiazi, let's sit and talk slowly."

Li Junxian, who continued to be on the sidelines: "..."

After all, he was also the commander of the Imperial Guard.

Erdan ran around the pharmacy, looking at all kinds of strange medicines, smelling really good, very interesting.

Xu Changsheng was pulled aside by the enthusiastic Wang Tao, and began to chatter.

Only then did Xu Changsheng realize that this little old man is a talkative guy.

He also said a few more words, "Spirited wine can kill germs. In fact, there are some germs on lily needles or other things. These germs are the root cause of inflammation and infection."

Wang Tao's eyes lit up. It really was a new medical theory. He took out a golden needle and looked at it. Xu Changsheng was taken aback when he saw it. The old man was really real.

Wang Tao looked at it for a long time, "I didn't see the germs you mentioned."

Xu Changsheng: "...these germs are so tiny that they cannot be seen with the naked eye."

Wang Tao was puzzled, "Since it is invisible to the naked eye, how do you know there are germs on it?"

Xu Changsheng thought to himself, how could he explain this?

Glancing at Wang Tao, his eyes flickered. This is a very famous doctor.

His college seems to be short of a school doctor, so he's going to fool a school doctor back.

After all, his college is on the top of the mountain. If a student has a problem and gets sick, it will be troublesome to seek medical attention. rest assured.

Although Xu Changsheng is treating big neck disease, treating heat stroke, and now stitching wounds, he is actually a layman. The only way he is better than others in medical skills is that he has more knowledge. If someone is really sick, rely on him It is not acceptable.

Xu Changsheng looked at Wang Tao, "The old man is very interested in my theory of germs? I am dissatisfied with the old man saying that Changsheng really has a way to let the old man see the germs that Changsheng said."

Wang Tao's eyes lit up, and he looked at Xu Changsheng, "Then..."

Xu Changsheng elongated his voice, "But, that's my treasure, and this knowledge is also unique..."

Wang Tao was entangled. He knew other people's unique skills, and he couldn't pass them on to the outside world. He would definitely not show them to him.

Xu Changsheng continued, "Actually, Changsheng has always had an idea. For things like medical skills, it would be great if all doctors could communicate with each other, so that patients in Datang would suffer less from illness."

Wang Tao was stunned, Xu Jiazi actually had such ambitions

His eyes lit up again, didn't it mean that he still had a chance to see the germs Xu Jiazi mentioned.

Xu Changsheng said again, "It's a pity that the world is like this, and Changsheng can't go against the way and be an independent person."

Wang Tao's eyes were full of resentment, whether to show him or not, hooked out the curiosity in his heart, it was like being caught by a cat, and now...

Xu Changsheng said, "It's not easy for Changsheng to break the rules, but Changsheng wanted to share medical skills with doctors all over the world, so Changsheng thought of a compromise method, setting up a medical laboratory in my college, and placing me Some of the studies that included facilities where we could see the germs."

Wang Tao frowned and blinked. Judging from his life experience, why does he feel that something is wrong?

But he was really curious about the new medical system, so he covered up his doubts and asked, "Then how can I visit the medical laboratory of your college?"

The corners of Xu Changsheng's mouth curled up, hooked.

Then he tidied up his clothes and bowed deeply to Wang Tao.

Wang Tao was stunned. Shouldn't he be asking Xu Jiazi at this moment?Why did Xu Jiazi give him such a big gift.

Xu Changsheng said, "Changsheng is shameless, I implore the old gentleman to go to my college and become a school doctor. Changsheng's college will also open a medical department. At that time, I will also ask the old gentleman to teach the students the medical knowledge of longevity, and then let the college Students benefit the entire Tang Dynasty."

Wang Tao was shocked, not because Xu Jiazi invited him to the academy, but...

Xu Jiazi is really planning to spread his unique medical skills and knowledge to the entire Tang Dynasty through the students of the academy.

Such a selfless act...

There was a trace of awe in Wang Tao's eyes, "You are really going to open a medical department in your college."

Xu Changsheng nodded, "In Changsheng's view, medicine is even more important than the six arts of a gentleman."

There is no medical school in Datang, and it is basically ancestral craftsmanship, or masters lead apprentices.

The spread of medicine is very small.

So Xu Changsheng's medical school was shocking to Wang Tao's ears.

Xu Changsheng said, "With one more doctor in the Tang Dynasty, more patients can be cured. I believe that my lord would not like to see the situation where the people of the Tang Dynasty have nowhere to seek medical treatment."

Wang Tao's eyes narrowed. He thought of the well-off life sayings of the Xu family in Chang'an, one of which was that everyone can afford to see a doctor.

Xu Jiazi was actually working hard in his direction.

The way Wang Tao looked at Xu Changsheng changed.

Xu Jiazi is probably the brightest light in this era.

Xu Changsheng continued, "I don't know if the old man is interested in helping Changsheng achieve this."

Wang Tao's heart trembled for a moment. Xu Jiazi's feat of setting up a medical school and spreading medical skills all over the world may be recorded in the annals of history. This is no different from the act of a saint.

Wang Tao took a deep breath. He sat in this medical clinic, healed many people, and saw many tragedies in the world, so he understood better than anyone else that Xu Jiazi's college could train one more doctor, and how much it would do to Datang. contribution.

He can save some patients by sitting here, but he can't save patients all over the world, but if he helps Xu Jiazi open a medical school, wouldn't he be indirectly treating patients all over the world.

What a merit this is, even Wang Tao couldn't help trembling in his heart.

Glancing at Xu Changsheng, he said, "The ambition of the Xu family is something I admire. Since the Xu family is so righteous at such a young age, how can the old man refuse to follow? However, the Xu family must first show the old man the equipment that can detect germs." Just look."

Xu Changsheng's eyes were all smiles, he succeeded in fooling around, and his school doctor succeeded.

The boss of the clinic was already stunned. As soon as Xu Jiazi came in, he robbed his chief sitter, and his forehead was blackened.

I've heard that Xu Jiazi has reached the point of going out of his way to find a teacher for his college, poaching corners everywhere, thinking about it, but never expecting to poach him here.

The boss stepped forward with a dark face, "Xu Jiazi, you...how can you be so reasonable, I usually take care of your Xu family's supermarket business every day."

Xu Changsheng was taken aback, and asked, "Who is this?"

Wang Tao showed an inscrutable look, and said, "This old man's boss."

Xu Changsheng: "..."

Xu Changsheng fled with Erdan, because Mr. Wang Tao's original employer was already looking for a broom.

After running out of the pharmacy, Xu Changsheng did not forget to say, "Old man, don't forget that you have already promised Changsheng, please go to the academy as soon as possible, my great grandfather will arrange everything for you."

The people watching the excitement outside were also very speechless. Whenever Xu Jiazi went out recently, he always poached someone else's corner.

However, Xu Jiazi's academy actually wants to open a medical department?

Doctors, in the eyes of the Tang people, are very respectable, but they have always been inherited by the family. Even if they take apprentices, they are basically collateral disciples of the family, and medical skills are rarely passed on to the outside world.

Xu Jiazi's move may soon cause a sensation.

And more people's eyes lit up, and they didn't know what the admission requirements of Xujiazi's college of medicine were. If they couldn't pass the imperial examination, being a doctor was also a very good choice.

Moreover, no one in Chang'an knew Mr. Wang Tao's medical skills. No matter how poor the medical skills of the students taught by him, they must be somewhat capable.

Xu Changsheng had already seen the owner of the clinic come out with a broom, and ran away with Erdan.

Li Junxian also came out, ready to thank Xu Jiazi for saving his soldiers.

At this time, Xu Changsheng turned his head and glanced at Li Junxian, his eyes were so strange that Li Junxian was a little terrified when he saw it, what does Xu Jiazi mean by this?

From a distance, Xu Jiazi's voice came, "Uncle, you have to be careful these days. Longevity looks at your face, and you will be tricked by villains recently."

Li Junxian was taken aback, when did Xu Jiazi become good at looking at people?

The soldier next to him said, "The commander really needs to be more careful, Xu Jiazi is very demonic, maybe Xu Jiazi really hit the mark."

Li Junxian never believed this, but when he thought of Xu Changsheng's gaze just now, he felt a little creepy, he should be more careful recently.

Xu Changsheng took Er Dan and ran to the Prince's Mansion. He was able to fool a school doctor and teacher whenever he went out, and he was satisfied.

Erdan was very happy, it was fun to go shopping with Changsheng, but it was a pity that the things he bought fell on the ground when he was running just now, and he didn't know who would pick them up, they were all brand new and still usable.

……

A few days later, Xu Changsheng went out every day. He went outside the medical hall to check. Wang Tao hadn't gone to the academy yet, and was still staying to take care of the soldier.

Xu Changsheng nodded, he was serious and responsible.

Xu Changsheng called a kid from the side, "Go and tell the old gentleman in the shop that the wound is almost healed, remember to remove the stitches, and I'll treat you to eat candied haws."

The children happily ran into the hospital with candied haws.

Xu Changsheng continued to wander around, looking around to see if there was any door to visit, maybe he was fooled into someone again.

only……

Xu Changsheng found out that when he visited recently, no one would let him in, especially when he went to Hongwen Hall and Chongwen Hall, the gatekeepers formed a circle to prevent him from taking a step, and even scolded him, black Dear Xu Jiazi.

Xu Changsheng's face turned dark, why is he so dark-hearted?

Well, his purpose of wanting to go in is indeed not very simple.

moan and groan.

However, don't think that if you don't let him in, there is nothing he can do. There is someone who looks forward to seeing him every day.

Xu Chang ran to the Prince's Mansion angrily, then rummaged through the box to find something, took it and went out.

His destination is... the palace.

Li Shimin wanted to see him a long time ago, and he had been pretending to be sick for so long, and if he continued to pretend, the car might overturn.

Come to the palace and ask for an audience.

Li Shimin was a little taken aback, that little bastard finally stopped pretending to be sick?

The corners of Li Shimin's mouth also twitched a little. A person who told him that he was sick in bed has been making a lot of noise recently. The whole Chang'an is surrounded by him. How dare he tell him that he is sick?

He wanted to see Xu Jiazi's explanation, and said, "Xuan."

When Xu Changsheng entered the Tai Chi Palace, he saw Li Shimin looking at him carefully, "How is my patient?"

Xu Changsheng was embarrassed, he was too troublesome to be treated as a patient, His Majesty was trying to control him.

Li Shimin was about to continue to make some decisions, to see if he would make Xu Jiazi blush.

At this time, Xu Changsheng said with a strong desire to survive, "Your Majesty, Changsheng came here this time to offer a gift."

After being told by Li Er, he was too embarrassed to look up.

Li Shimin was taken aback for a moment, and said, "Really? Let's see how you evade it."

Xu Changsheng pretended he didn't hear it, and continued, "I don't know how your Majesty's eyesight is?"

Li Shimin was stunned, but he was used to Xu Jiazi's way of speaking, so he replied, "That's good."

He also went to Xu's glasses shop to test his eyesight, and he didn't need to wear glasses, so his eyesight should be good.

Xu Changsheng said again, "Who among His Majesty's sharpshooters has the best eyesight?"

What a strange question.

Without waiting for Li Shimin to continue, Xu Changsheng said, "Your Majesty, no matter how good your majesty's sharpshooter eyesight is, Changsheng can be sure that Changsheng can see farther than him."

Li Shimin was taken aback, "Are you so confident?"

Xu Changsheng raised the object in his hands duangly, "Of course, as long as there is something in Changsheng's hand, anyone has better eyesight than a sharpshooter."

Li Shimin:  …

Who did Xu Jiazi say?

Marksmen are generally spies in the army, because they have better eyesight than ordinary people and are extremely useful. Unfortunately, there are very few such people, not many.

Xu Changsheng smiled and pointed to the outside, "How about going out with Your Majesty and Changsheng?"

Li Shimin glanced at the long tube-shaped object in Xu Changsheng's hand, and stood up. He wanted to see what could be so miraculous. If it was as Xu Jiazi said, wouldn't everyone be able to spy on the military for the army.

When he came outside the door, Xu Changsheng pointed to the patrol team who couldn't see clearly in the distance, "Your Majesty can clearly see how many people are in that team of guards?"

Li Shimin tried his best to look, because it was too far away, although he could see people, he couldn't tell how many people there were.

Xu Changsheng took a look at the objects in his hand and said, "There are 13 people in total."

Li Shimin was taken aback, and looked at the object in Xu Changsheng's hand.

Xu Changsheng smiled, handed the object over, and said, "This is a telescope. As the name suggests, it can make the distant scenery look closer."

Then teach Li Shimin how to use it.

Li Shimin put the telescope in front of his eyes.

Then they were all stunned.

The picture is really as if it is right in front of your eyes. There are exactly 13 people on the patrol team. Not only that, he can even see the opponent's every move clearly.

Li Shimin is sure that even the most powerful sharpshooter can only see how many people are at most, and it is impossible to watch the opponent's every move.

Telescope?

It is really an appropriate name. If it is used in the army, it can play a role in insight into opportunities. One can imagine how effective it will be.

Xu Changsheng said again, "Your Majesty, please look at that mountain."

It was a very distant mountain.

Li Shimin took a look through the binoculars. This time he was really shocked. This is simply beyond the range of human vision. I am afraid it will be more effective than he imagined. Imagine that our side can control the enemy's movements at any time, and the enemy The army knows nothing about our army, whether it is an ambush, dispatch or retreat, can it be arranged in advance.

Xu Changsheng took the telescope from Li Shimin's hand, adjusted it pretendingly, and put it behind his back.

Li Shimin was stunned for a moment, what does Xu Jiazi mean by this?

Xu Changsheng said, "Your Majesty thinks, what if Changsheng sells binoculars in Xu's Supermarket?"

Li Shimin's face immediately turned black, "Bold."

If this thing flows into the hands of other forces, wouldn't it be a great threat to Datang?

Xu Changsheng smiled, "Of course Changsheng doesn't dare to let it flow out, isn't this here to present treasures?"

Li Shimin glared at Xu Changsheng.
