Jia She's eldest son of the Red Chamber

Of course, the reason why Jia Hu stayed and insisted on refusing to leave was not only because he, as a member of the Jia family, could not abandon the city, but also because he learned from Jia Lian that even though the Liaoyang Mansion was trapped For a while, it was not breached by the Beirong people, so the Liaoyang Mansion was barely considered a safe place.

In Jia Lian's memory, Wang Ziteng was promoted three times because of his meritorious service in defending the city. Not only did he gain a firm foothold in Liaoyang Mansion, but he also became No. The reversal of the status of the two families also started from this battle.

Of course, now that Jia Amnesty is here, Zhang Zhiping is also a formidable person. Naturally, it is impossible for Wang Ziteng to take all the credit alone. Besides, Wang Ziteng had such a great contribution in his previous life. When the prefect had a problem, he decisively and directly killed the prefect of Liaoyang at that time, but now...

In the case that the prefect of Liaoyang has been replaced, Wang Ziteng is not like the military and government in his previous life, so the credit is naturally a little less.

However, as far as Wang Ziteng himself is concerned, I am afraid that he is not willing to be caught by the general military and political affairs like in his previous life. This right is certainly great enough, but it is also very tiring. The person cut 'somewhere' because there was only one woman under his knees in the previous life.

Of course, Jia Lian would know this because he is the son-in-law of the Wang family, otherwise it would be impossible to know this.

After hearing this, Jia Hu made a golden bell cover for himself for private use. He hasn't used it yet. Dad got one too.

Although he didn't want his father to have a chance to be useful at all, maybe his mother would wake up that day?It is very possible to add another younger brother and sister to him. After all, Mrs. Wang is pregnant again. Seeing that Yuan Chun is about to be born, will Ying Chun be far behind?

Not to mention the black lines on Jia She's face when he received this object, and the fact that he figured out the purpose of this object without a teacher. For a while, but soon stabilized again.

Seeing that the situation was urgent, Jia Hu no longer hid it, and took out all the little things that he had made over the years.

He can't make fire/guns. After all, the technical content of fire/guns is too high, and the modern technology level cannot be produced in an assembly line. Every part is made manually, which is time-consuming and laborious. Black fire/powder-based fire / The range of the gun is limited, it is better to use this time to make other weapons.

But although he can't make fire/guns, he can still make other things. The telescope is the first, the mines are the second, the grenades are the third, and the technical improvement of the artillery is the third.

As early as the former dynasty, there were so-called cannons, such as the General Cannon and the Tiger Crouching Cannon that still guard the city wall of Liaoyang Prefecture are left over from the previous dynasty. In all honesty, these cannons were considered the highest level of craftsmanship at that time. , the casting is not bad, there is no cutting corners, but the range is always a bit worse, and it is only four to 500 meters. To put it bluntly, it is just the range of an ordinary rifle/gun.

Moreover, after the first shot, the artillery had to wait for a long time to cool down before firing the second shot. While waiting for the artillery to cool down, the Beirong cavalry had already killed countless times back and forth.

If you really want to defend the city, it stands to reason that it is best to use the Hongyi cannons from Europe. The Hongyi cannons that were supposed to be sent at that time did not come, and they were replaced by some small cannons with a short range.

But fortunately, Hongyi Cannon hadn't been passed on at that time, otherwise...he probably wouldn't be there today.

Jia Hu had studied the Hongyi cannon in the field, and knew the data of the Hongyi cannon in detail, but no matter how much Wang Ziteng valued Jia Hu, he would not trust him in this matter, and Wang Ziteng did not have the right to make cannons. So that's all.

However, Jia Hu can improve the general cannon and the tiger squat cannon in front of him. The range is hopeless, and it will be faster to destroy it. Can help some.

In this era, many gunners just blindly fill the shells. Sometimes, when they are in a hurry, they will fill two shells at once. Quantify the amount of gunpowder and filling, match different gunpowder/powder amounts according to different shooting ranges, and pack each pack with oiled paper separately.

It is much better to directly unpack a pack of filling each time it is fired than the previous gunners who filled the black powder/powder randomly based on their experience.

The other is the problem of heat dissipation. Even if you don’t understand what heat dissipation is, any experienced gunner will know that every time a cannon is fired, the cannon must rest for a while before firing the second cannon, otherwise the cannon will be easily damaged. Damaged and unable to withstand the high temperature and pressure generated during the explosion, the chamber exploded.

This problem is unavoidable unless you cancel the retraining and directly change the material of the casting cannon.However, Jia Hu can use calculations to figure out how long each cannon will rest before firing the next cannon.

In addition, Jia Hu also uses mathematical calculations to calculate the angle and range, reasonably arranges the position of the artillery, adjusts and staggers the firing time and firing angle of each artillery, so as to achieve the highest covering rate of the artillery range.

It took Jia Hu several days to make these adjustments to the existing artillery. At first, the Liaoyang army thought it was troublesome, but because of his surname Jia and Wang Ziteng's strong support, this It was barely enough to allow Jia Hu to fool around. Unexpectedly, after a little experimentation after the setting, everyone fired a round. Not only did the seven cannons fail to explode, but the shells did not fall where Jia Hu predicted.

Now, no one dares to underestimate the child Jia Hu, and many people even call him Little General Jia. With Jia Hu's ability alone, even an old gunner in the artillery battalion can fight against Jia Hu. Sometimes I have to say a word of service.

However, Jia Hu was still quite dissatisfied with this, and complained to Wang Ziteng, "The speed of heat dissipation is still a bit slow. After one round of firing, all the cannons have to stop. Even so, the possibility of the iron cannon exploding is still high." , after all, it’s a bit dangerous.”

Jia Hu sighed, "If you have money, you should make bronze cannons."

He really didn't understand why the court didn't make bronze cannons. Looking around, all the cannons were iron cannons. Even if he tried his best to time and quantify them, iron cannons have poor stability and are prone to small cracks. Again, in comparison, although bronze cannons are more expensive, they are much more stable than pig iron in terms of metal material, and are not easy to explode. Generally speaking, pig iron cannons are much better.

Wang Ziteng said, "You should be content! It would be nice to have guns here, but there are no guns in other places."

Wang Ziteng glanced at Jia Hu enviously. Although he was educated in his family, this kid is really good. Although he doesn't like reading, he comes from a family after all. It's not like he didn't know the mathematics that brother Hu said. I have learned it, but no matter what, I can't say that I used mathematics to the extreme like Brother Hu, and he was really ashamed to see it.

Jia Hu shook his head, "The artillery can only defend for a while, and after a long time, it will eventually fail."

Fire/powder and shells are limited, and a cannon without fire/powder and shells is nothing more than a bulky piece of scrap iron. I am afraid that in the end it will still have to rely on cold weapons.

Wang Ziteng smiled and said, "With grenades and landmines, our chances of winning are much higher than before." He sighed, "It's also thanks to your father who ordered the shops in the city to be controlled first, or we would have to fight together." I'm afraid there won't be so much gunpowder in time, as for the future..."

Although Zhang Zhiping complained a lot before, this is indeed the best way. If you do extraordinary things in extraordinary times, the enemy will be killed, so you can't take care of other things.

Ordinarily, there should be gunpowder in the Liaoyang Mansion, but the court withheld it, and they don't know where to allocate the money. Most of the gunpowder they use is freshly prepared.

Fortunately, Jia She has controlled the shops, so he has the materials to make fire/powder. However, charcoal is easy to accumulate, but saltpeter is in short supply. The most important ingredient in the formula of fire/powder is saltpeter. It is difficult for a smart woman to cook without rice , right now, he can only take one step at a time.

"It's really at that time," Prince Teng paused, "Your Uncle Wang and the big knife in my hand are not vegetarian."

Without materials, Jia Hu had no other options. He could only work hard on other aspects. Whether it was the training of soldiers or the use of cold weapons, he was involved. Stop, Wang Ziteng also blindly let him.

The cold weapons of the Great Jin Dynasty can be said to have developed to the limit. Although limited by metal materials, the design of knives, swords, and crossbows is almost the same as that of modern times. The rest is the materials and manufacturing that cannot be surpassed temporarily. technical problem.

Faced with these, ordinary people should have no other way, but who is Jia Hu? Human spear throwers are among the strongest.

Jia Hu took a closer look at the training in the army and wondered, "Why don't people use spears?"

Although this spear is not as light as an arrow, its lethality is much greater than that of an arrow.Arrows can't break shields, but spears are different. If the power is right, spears can even break shields!

Wang Ziteng shook his head, "The spear is too bulky and inconvenient to use. When it comes to hand-to-hand combat, it is more convenient to use a sword."

"Close-to-hand combat..." Jia Hu pondered, "Has Uncle Wang ever thought about using the throwing method?"

Although the spear is bulky, it is one of the few cold weapons that can pierce the shield. The Beirong and the Dajin have fought for many years, and they are familiar with the existing attack methods of the Dajin, so they must have shield soldiers.

Although in the early stage, artillery can be used to bombard hard, but what if the shells are gone?Spears are far more useful than arrows or crossbows against shield soldiers.

When Jia Hu mentioned it briefly, Wang Ziteng understood what he meant, and said, "It's better to use artillery."

The spear was thrown too close, and it was useless.To throw it far, it consumes a lot of energy, which is far less convenient than artillery.

Jia Hu was not good at arguing with Wang Ziteng, so he suggested, "Let's make a record."

After all, they had used up all the saltpeter in stock. If they were still unable to defeat the Beirong people after all the shells were fired, they would have to use cold weapons.

Jia Hu drew something on the paper, "This is a spear thrower. If it goes well, it should be able to throw more than [-] meters with ease."

China doesn't take spears seriously, but in Europe and America, spears can be said to be one of their most commonly used weapons. Not only did the ancient Roman Empire have so-called spear throwers, but even the Indians also had them, and they even gave birth to the The so-called spear thrower can easily throw the spear over a hundred meters.

At that time, the Indians had fought with the Spaniards who were holding thermal weapons for a long time by relying on spear throwers, and they could change the history of the world just a little bit. You can see the potential of the spear thrower.

In addition, Jia Hu also drew the Bolas stone throwing tool. This thing is nothing special, but it is just three round weights tied to the rope, which are thrown when used. South American natives People use it to catch camel horses, but Jia Hu changed its use a little, and used it to bind the horse's legs.

Once a horse is injured in its leg, it will lose its mobility. Even if it is raised well, it will not be able to be a war horse. The most dangerous of the Northern Army troops is the cavalry, but as long as the cavalry has no horses, there will only be them It's time for slaughter.

It's not that Wang Ziteng has no doubts about how Jia Hu came up with so many ideas, but Jia Hu threw out mathematical theories one after another. Wang Ziteng just listened to it and fell asleep. I couldn't understand it at all, I just felt that Brother Hu was right.

Wang Ziteng can only whisper to his wife in private, this is probably the gap between a top student and a bad student, obviously he has also studied mathematics, why can't he come up with some improvements like Brother Hu? The solution.

Wang Ziteng finally sighed, "It would be great if the child in your womb was born a few years earlier."

The doctor has already confirmed that the fetus in Wang He's womb is a daughter. Wang Ziteng is not a pedantic person. It is not bad to bloom first and then bear fruit. It would be a beautiful thing not to let Brother Hu be his son-in-law.

Wang Ziteng did the math, even Wang Xifeng who was in the next room was only just born, and his age was far behind Brother Hu's. It seemed that their Wang family was unlucky after all.

Wang He touched her chubby belly, and gave Wang Ziteng a look, "Who told you not to let me come earlier."

If she had come earlier, she might have several children, and naturally there would be a prostitute who was about the same age as Brother Hu to marry.

Wang Ziteng smiled awkwardly, stretched out his hand to touch Wang He's belly, and sighed, "I regret letting you follow me, and I don't know about this battle..."

If Wang He didn't come, even though the husband and wife were separated, at least they wouldn't have to worry about following him, and their children might grow up safely.

"What nonsense!" Wang He said angrily, "We are husband and wife, so we must live and die together."

As for the child... Rather than letting the child be a fatherless and motherless person, living according to his uncle and aunt, it is better to go with the couple.

"Besides, I believe in you!" Wang He looked at Wang Ziteng with wholehearted admiration and trust in his eyes, "I believe you will win this battle!"

Looking at Wang He's completely trusting eyes, Wang Ziteng suddenly became angry, "Well said! It's just a few Beirong people, and they can't come back if their husband needs them!"

Since you dare to offend him, then leave your life in Liaoyang Mansion.

The news of the large-scale attack of the Beirong people is unstoppable. After all, the Beirong and the Jin Dynasty have been trading each other for a long time. When the Beirong army moved, many merchants from the Dajin received a little wind and hurried back to Liaoyang Mansion. Unexpectedly, among this group of merchants there was an old friend of the Jia and Wang families—Xue Yi, the head of the Xue family.

Although Xue Yi is the head of the Xue family and Jia Zheng's brother-in-law, in Jia Hu's eyes, he is far less famous than his future daughter, Xue Baochai.

At this time, Xue Yi is just a young man in his twenties, he has just married Aunt Xue, and his face is still a little childish, but as soon as he speaks, Jia Hu knows that this person can do such a thing. The imperial merchant for many years left millions of property to Xue Pan after his death, so he really has some real skills.

As soon as Xue Yi came to Liaoyang Mansion, he told about the Northern Rong Army's intention to attack Liaoyang Mansion.

"Brother Enhou, I think the Beirong people are serious this time."

Xue Yi said, "It's not just the Beirong Khan's personal conquest, I also saw the flags of the Yehe tribe, the Eqin tribe, the Wanyan tribe, the Ula tribe, and the Yishi tribe. Among the eight major tribes of the Beirong tribe, five of them have emerged. I'm afraid that the Beirong Khan is bound to win the battle!"

Jia Amnesty couldn't help raising his eyebrows, "What a big battle!"

It seems that Sangbu really spent his money this time.

Xue Yi nodded and said, "However, I think Beirong Khan arranged the Wula tribe and Wanyan tribe as the forwards, which seems to be suspicious of these two tribes, and the flags of these two tribes do not represent the king's flag of the tribal leader. It is the second-class Left Banner, and the cavalry brought by these two tribes is also the least."

That's all for the Wanyan tribe. The Wula tribe has always been famous for producing horses. It's really not good to have only such a few cavalry. It seems that the Wula tribe is quite dissatisfied with Beirong Khan.

Xue Yi not only gave an approximate location of the Beirong army's barracks, but also recorded the number of cavalry.

While recording, Jia Amnesty said with emotion, "Brother Xue has worked hard!"

Beirong's intention to attack Jin is not a secret, that's all, but what is rare is that Xue Yi can remember clearly the distribution of troops in each tribe, which shows that he really put in a lot of effort.

With this information, they are more confident in dealing with the Beirong army.

"Yi is from the Jin Dynasty, and this is within Yi's job." Xue Yi's smile was a bit shy, but he was not ambiguous at all in his actions.

Xue Yi said sternly, "Yi is just a businessman. Although he can't defend the country with all the soldiers, he still has a heart of patriotism. Yi is willing to donate all the goods on this trip, hoping to do his part for the Great Jin Dynasty." .”

As soon as these words came out, even Zhang Zhiping, who hated the rich the most, had to admire. Although Xue Yi donated only the goods from the merchant this time, the Patriarch of the Xue family would personally send the money, which shows the importance of this batch of goods. value, and Xue Yi donated as soon as he said he would donate. Jia Amnesty, who is not short of money, secretly admires this kind of courage.

Zhang Zhiping quickly said, "Mr. Xue is a true patriot. Zhiping would like to thank you on behalf of the people of Liaoyang Mansion."

"Master Zhang is polite." Xue Yi hastily said a few more polite words to Zhang Zhiping. Just as the two of them were being polite, Wang Ziteng suddenly sent someone to report that he had seen the striker of the Beirong people!

As soon as they heard the arrival of the Beirong people, everyone was waiting in full battle. Prince Teng kissed the city wall, and even Zhang Zhiping and Jia She couldn't sit still and came to see for themselves.

Unexpectedly, just as Jia She went up the city wall, he saw a person who shouldn't be here!

Jia She shouted, "Brother Hu! What are you doing here!?"

In the past, Jia Hu ran around the city wall every day, and even got the name of little General Jia. Jia Amnesty didn't know about it, but he just turned a blind eye.

But he never expected that Jia Hu would run to the city wall at such a critical time, which really frightened Jia She.

Jia She shouted, "Is this the place where your children's family should come? Hurry up and go back, don't disturb your Uncle Wang!"

As he said that, he really let the servant drag Jia Hu away.

"Father!" Jia Hu explained while struggling, "I have to stay here so that I can adjust the angle of the artillery at any time!"

Although he has adjusted the firing angle of the artillery as much as possible, and also helped train a group of artillerymen, the Beirong people are not dead, they will only stay in one place, and he has to follow the Beirong people at any time. Adjust the position of the muzzle is.

And this matter really cannot be entrusted to others, even Uncle Wang, who claims to have studied mathematics, his mathematics is so bad that it is admirable. In the case of their limited fire/powder, in order to avoid wasting fire / Medicine, Jia Hu has to stay on the battlefield, and it is most appropriate to adjust the shooting angle according to the actual situation.

"How is it possible?" Jia She didn't believe it. "It's just a few calculations, so there is a reason why you must."

"It's true." Jia Hu looked innocent, and directly pulled a artilleryman and said, "Let me ask you, how much is two times three?"

Beads of sweat dripped from the artilleryman's forehead, "Back to General Xiao Jia, San?"

Jia Hu stared blankly, "The answer is six. Let me tell you, Ah Hui, I have tested you three times for this same question, so even Bei should memorize this answer, right?"

He always asks how much is two times three?Anyway, it should be memorized.

Hearing that Jia Hu knew his name, Ah Hui was so excited. He never thought that he had only spoken to General Jia a few times, and General Jia would remember his name. Ash Hui hurriedly replied "Yes! The younger ones must remember, it's six!"

No problem, he will ask his kid to change his name to Liuliu when he goes back, so he will definitely remember it in the future.

"Uh... I hope you can count." Literacy is not a matter of a day or two, and it is difficult for these people who can't even read to learn curve mathematics. Jia Hu waved his hand helplessly, "Forget it, you go back Take your seat."

"Yes!" Ah Hui hurriedly stood back in front of the cannon, his posture was as standard as it could be.

Jia Amnesty was speechless, "If you ask them, of course they won't know. I don't believe that your Uncle Wang can't answer."

As he spoke, Jia Amnesty looked directly at Wang Ziteng.

Wang Ziteng coughed lightly, and turned his face away without loyalty.

Jia Amnesty's jaw almost dropped from shock, and he said heartbrokenly, "Brother Wang, you let me down so much!"

Xd, he thought that only the younger brothers and sisters of the Wang family were ignorant, and it turned out that Wang Ziteng was the same, no wonder he wanted to take the road of military officer!

Wang Ziteng closed his ears, he didn't hear anything.Of course, he can count two times three, but what if Brother Hu comes up with two three times three two?What is the elevation angle of 43 degrees...

Don't pretend that he doesn't know, Brother Hu's calculations are not human calculations at all, he... really doesn't know how to calculate.

During the conversation, Bei Rong's first test of Da Jin began.
