Li Shimin's will: Li Zhi, the throne belongs to your brother

With the current productivity, I am afraid it is impossible.

"Father...I'm afraid... the national power won't allow it!!" Li Tai immediately poured cold water on it, you Li Er is too whimsical.

"Cough..." Li Shimin, who was being led by Li Tai, forced an explanation with a dry smile: "Of course I know, but I will definitely make [-] cannons in the future."

"···"

"However, I also want to try firing cannons." Li Shimin looked at the cannons with longing and longing. Who wouldn't want to try such a terrifying weapon like cannons with their own hands?

"Your Majesty...this..." Li Chunfeng and the others were frightened by Li Shimin's thoughts and were speechless for a long time.

千?'寻:小;,说":资!源'中!转,:裙?2"0:.6"8"5;6":0?5;8　　李泰更是一惊，深吸一口凉气。

This is death!This is a cannon, if you, Li Er, make a mistake, it will be gone on the spot! !

Thinking of this, he hastened to persuade: "Father, this cannon still has many flaws, and it is extremely powerful. If there is a slight mistake... I'm afraid."

I'm afraid something unexpected will happen, you Li Er... Although you haven't finished speaking, Li Shimin has already understood.

Instead of being afraid, he retorted: "Flaws? Why didn't I see the flaws? Besides, they are all fine, so how could I be okay?"

"..." Li Tai was very speechless, watching Li Shimin's rebuttal, he mercilessly revealed all the shortcomings he knew.

"There are too many flaws." While speaking, he cast a contemptuous look at Li Shimin, then turned his head and said to Li Chunfeng.

"First of all, this is the explosive bag, the fuse and the explosive bag can be separated when making it.

Otherwise, the lead wire is exposed outside, and if it is hot summer, it is easy to ignite the lead wire if you are not careful, and the consequences will be disastrous. "

Li Chunfeng and others nodded after hearing this. This is indeed a problem. The reason why they didn't encounter it is because it's been winter recently.

"Secondly, the explosive package made of gun cotton can't withstand the pressure of such a large iron ball, and it is easy to explode directly if you are not careful.

If the bomber didn't leave in time, he might be crushed to pieces. "

This problem, Li Chunfeng and others can only bow their heads. To solve this problem, many things have to be changed, such as the method of launching, or the structure and so on.

Although Li Tai didn't manage much of these explosives, he could see the problems at a glance.

With mathematics, physics and chemistry, the development of science and technology is too fast, safety awareness, preventive measures...too many things have not kept up.

"Is it really that scary?" Li Shimin looked as if he was admitting his mistake, and then realized how terrifying this cannon is.

"Why did I lie to you!?" Li Tai gave Li Shimin a speechless look.

"..." Li Shimin was so stunned that he had nothing to say, he could only sigh and ask, "Then when will I be able to fire the cannon myself?"

Upon hearing the question, the group of people fell silent immediately.

There is a saying that everything is difficult at the beginning, but in fact it is not only difficult at the beginning, but also difficult in the middle, and even more difficult in the end.

What's more, when it comes to scientific research, no one can give an accurate time.

Suddenly, Li Chunfeng remembered something, raised his head and said to Li Shimin: "Your Majesty, how about I get you a model to enjoy yourself?"

"Model?" Li Shimin shook his head and was speechless: "This model...is it still enjoyable?"

"Your Majesty, don't underestimate the model. Even if the cannon is a hundred times smaller, its lethality is still very impressive."

"Alright, then bring the model over here!" Li Shimin waved his hand in a lack of interest. Although he couldn't touch the cannon, it was still possible to play with the model.

"Yes." Li Chunfeng quickly agreed, but when he turned to get it, he remembered something.

Then he turned back and asked Li Shimin: "Then, Your Majesty, what should we do with this cannon?"

This test gun has been tested. Although the accuracy is a little bit off, the range and power are amazing. At this time, it can be said to be a perfect weapon.

But the shortcomings are also very obvious, high cost, high consumption, various safety hazards... It is a bit unbearable to want large-scale equipment.

Thinking of this, Li Shimin was also very hesitant for a while, whether to mass-produce it or not?

Seeing Li Shimin's changing expression, Li Tai hurriedly stopped him and said, "Father, I think it's better to wait."

"Oh, why is that?"

"This copper-iron alloy treasury may not be able to support it. Besides, if the steam engine has been made, then the hammer machine can be made, and better steel can be obtained."

"The disciple also thinks the same way. With steam hammering, he can swing a bigger hammer and produce a large number of all-steel cannons."

"The cutting on the industrial mother machine is actually an industrial hammer machine."

Several disciples showed relaxed expressions, obviously they also thought of this.

If a hammer machine is made, it will have the ability to process a large amount of high-quality steel.

There is no need to use copper-iron alloy, which can save a lot of money.

"In addition to the hammer machine, there are various mineral metals that can be used, such as tungsten, manganese..."

If tungsten was mined, it would allow for better barrels.

In fact, most of the gun barrels and gun barrels are now made of tungsten steel, and the performance is much better than that of copper-iron alloy.

Tungsten is a strategic material, even a little bit of tungsten will change the properties of the metal dramatically.

In ancient times, it was usually cast into a magic weapon that cuts iron like mud. Interestingly, due to the low temperature, tungsten would be disposed of as slag.

It’s just that the melting point of tungsten is as high as 400 degrees, and even tungsten steel is [-] degrees. The difficulty of processing is very high, and blast furnaces cannot use electric furnaces or chemical methods.

This cannon is completely, the performance is not enough, and the weight comes together.

At the same time, subject to performance, the structure does not dare to make too many changes.

Chapter 129 Assigning Tasks

"Tungsten and manganese?" Li Chunfeng hurriedly took out a pen and paper from his sleeve, and wrote down these two metals.

"What's so memorable about this." Li Tai waved his hand a little speechlessly.

"Each metal has its own characteristics. It is useful to just write it down. You have to constantly research and discover and use metals."

Li Chunfeng listened, stopped the pen in his hand, looked up at Li Tai and said, "Master taught me the lesson!"

"The disciple resigned?"

"Go."

Li Chunfeng beckoned, leading several people to trot all the way towards the direction of the blast furnace base.

It didn't take long for Li Chunfeng to bring back his disciples, and he also brought back a cart of tinkling metal.

Li Tai glanced over and found many steel pipes of various sizes, some of which could be identified as brass at a glance, while others looked like steel.

Looks like various different types of water pipes.

Li Chunfeng picked up a [-]cm copper-iron steel pipe with a diameter of [-]cm.

"Your Majesty, this root is a shrunken model, but even the shrunken model can have impressive power!"

While talking, he filled gunwool and steel balls one by one, and then filled the gun barrel to a metal device and fixed it.

Li Tai was very surprised. Although it was a miniature model, this thing looked like an early single-shot gun.

Li Chunfeng glanced at it, and had an idea to use the sandbag as a target. While waving to drive away the people in front, he said, "Stay away, this is a model cannon!!"

It sounded like a model cannon, and everyone ran behind Li Chunfeng like swallows returning to their nests.

"Your Majesty, please be careful." As Li Chunfeng said, he put the metal device that fixed the barrel into the ground, connected a lead wire to the back, and took it.

Then he took out a torch from his sleeve, and after blowing on it, he slowly reached out and lit the fuse.

In an instant, the fuse burned out, and there was only a 'bang', and the metal device seemed to have been pushed back by a heavy hammer for a certain distance.

At this point, a red light flashed across the air, and a hole appeared in the sandbag, from which fine sand slowly leaked out.

Li Tai looked at it with a complicated expression.

There is not much difference in the principle of guns, even in the early days, the structure is not much different, they are all front-loaded with gunpowder and front-loaded steel balls.

"This power is really impressive!" Li Shimin squinted at the sandbag, thinking of something and asked, "The distance is 20 meters!?"

"Report to Your Majesty, yes."

"Then what is the farthest distance?"

Li Chunfeng replied at a glance what Li Shimin meant.

"The furthest distance of this model cannon is only 50 meters to have lethality, but it can shoot 300 meters and is almost the same as a crossbow bolt."

Li Shimin shook his head after hearing this.

Even Li Tai shook his head when he heard this. The 50-meter killing range is similar to that of a crossbow. In addition, the Zhuge Liannu can fire continuously, and this thing needs to be ignited.

No matter how you look at it, you feel that the crossbow arrow has been reborn.

Early firecracker guns are hard to compare with crossbow arrows in terms of rate of fire, range, plus ignition and barrel cleaning.

"Your Majesty, do you want to try?" Li Chunfeng raised his head and said to Li Shimin with a smile.

Li Shimin looked at the mood and said:

"After seeing the power of the cannon, I just feel like a child's juggling when I look at it again~"

As soon as these words came out, the atmosphere immediately became quiet.

Several people looked at each other, exchanged glances, and finally Li Chunfeng stood up and spoke.

"It's my fault. As long as I give you some more time, I will definitely make a safe cannon."

Li Shimin looked at the cannon being carried onto the car, with a look of reluctance in his eyes without looking back. "I'll wait and see."

"Then, Your Majesty, do you want to go back to the base?"

"No, I'll be out for a long time, it's time to go back to the palace." Li Shimin looked at the sky, turned to Li Tai and said: "The emperor is here to deal with the cannon, let's go back to the palace."

"My son obeys the order." Li Tai bowed his head and saluted.

"I will send you to Your Majesty."

···

Not being able to try the cannon himself, Li Shimin could only go back to the palace in displeasure.

"Let's go back to the base." Li Tai waved his hand, signaling the team to go back.

The group returned to the base and began to report their progress.

"Li Chunfeng researched gun cotton, Yang Siqi researched steam engine, Zhang Yajiu researched muzzle gun, Yuan Keshi researched clairvoyance.

It can be said to be quite rewarding! "

Li Tai held a pile of drawings and materials, and said very satisfied.

"Thanks to Master's instruction, this disciple has fulfilled his mission." Several people stood up with smiles on their faces and said in unison.

"Whether you are a good teacher or not, you are the real scientists. Only relying on everyone here, Datang can become stronger."

"The disciple will definitely continue to be angry."

"Yeah." Li Tai waved his hand, signaling everyone to sit down quietly.

"Presumably you have already felt the lack of manpower. After returning to the palace, I will apply for more people and supplies with my father. You take care of them.

As for supplies, feel free to ask for anything.

As the saying goes, being a teacher for a day is a father for life!

Although I am not as old as you, this guarantee can be achieved. "

"Disciple, thank you master~"

After hearing that someone had supplies, everyone was immediately happy, and asked for someone one after another.

"Master, can you arrange five hundred people for the disciples!?"

"Five hundred, why don't you grab them?"

"A steam engine has hundreds of parts, and it is reasonable for me to need five hundred people!!"

"Then why don't you say that I am far away in Gaochang, and I want 1 people to go to Gaochang to steal some? Is that also reasonable?"

"···"

Several people were arguing, although there are only steam engines, cannons, gunpowder, and binoculars, but there is already an extreme shortage of people.

More than 200 people are really too few, but fortunately, the most indispensable thing in Datang is people.
