Bai Erwa flew up, and flew up under the power of the four horses.

It is a pity that the flexible surname, stable surname, and ** vertical surname are far inferior to those brought by Li Yuanxing from later generations. This is the gap in craftsmanship.Li Yuanxing approached Li Changying: "Changying, my lord congratulates you. This kind of achievement is very good. I am very satisfied, but you also need to take good care of yourself. You have lost weight these days!"

With a few words of praise from Li Yuanxing and words of comfort, Li Changying almost burst into tears of excitement.

Li Yuanxing patted the back of Li Changying's hand twice, then picked up the binoculars, posing to watch Bai Erwa fly.In fact, Li Yuanxing was communicating with the time machine at this time.

"Is there any result?" Li Yuanxing asked the time machine.

"The time difference is four times, there must be other items produced. But according to this steam engine, it has proved the four times inevitable relationship." The time machine gave an affirmative answer.

Li Yuanxing asked again: "I have always suspected that these are all in movies or animations."

"Your speculation is wrong. In theory, it can be achieved. But in your era, only because of more efficient methods, the use of steam engines is only in a single direction of mechanical kinetic energy. Such a steam cannon, if In the era of human beings, it can be made even more brilliantly, and the air pressure can reach more than [-] Pa. But the one you see in front of you is only about [-] Pa."

Li Yuanxing seemed to understand: "I think Yaozhou should be researching steam turbines, the pinnacle of steam power!"

The time machine did not answer, as if it had acquiesced to Li Yuanxing's guess.

"Additional question! Cannons and steam cannons are theoretically more difficult to manufacture?"

"Cannon!" After the time machine gave an explanation, he stopped expressing his opinion.Why artillery is more difficult, this is something Li Yuanxing needs to learn and research by himself.

Li Yuanxing put down the binoculars, and Bai Erwa had already flown back.

"About this cannon, I need a detailed report!" Li Yuanxing put the binoculars on a small table beside him.

It is not Li Changying's task to hand in the report. She leaned beside Li Yuanxing: "Your Highness, the alchemy masters originally planned to use gunpowder for fireworks to make cannons, but unfortunately they didn't even fly a hundred steps after loading the iron bullets. The amount of gunpowder was large, but the barrel was blown apart, and the iron bullets did not fly out."

"En!" Li Yuanxing nodded.

Although Li Yuanxing did not go to college, even if he went to college, he might not be able to learn similar majors.True knowledge still comes from a lot of reading.

What Li Changying said originally, Li Yuanxing could understand that the strength of the gun barrel is a problem. Now it is made of gunpowder, not explosives. Explosives of sufficient purity are needed.

"Your Highness, this cannon is inspired by that little snack tool!"

"Small dim sum?" Li Yuanxing couldn't think of anything that could make dim sum into a cannon.

"It's popcorn!"

Popcorn!

Li Yuanxing smiled, that thing is really powerful. I remember that long iron ball was burned on the stove when I was a child, and then the strong air pressure turned the corn kernels into popcorn. The moment it was finally opened, there was a bang, full of power .

But what about multiplying that power tenfold?

Li Yuanxing thought of this, and motioned for a cannonball to take a look.

The guards brought three cannonballs, all of which had almost the same shape, and the most interesting thing was that each cannonball had three rings.

"Your Highness, the first is a wooden ring, the second is a plastic ring, and the third is an oil ring." A personal guard brought three more rings.

Li Yuanxing nodded and signaled the guard to continue talking.

These three rings, to put it simply, increase the airtightness, increase the lubrication, and reduce the friction with the barrel.

"Your Highness, the first iron bullet is a solid bullet, with a pointed iron bullet at the front and a lead shell at the back. The second iron bullet is a hollow bullet with a phosphorus bullet at the front, gunpowder inside, and some small Iron nails. The third is also a hollow bullet, loaded with kerosene, and also used phosphorus to ignite the front end of the warhead!"

"Go and try it!"

Li Yuanxing played with the air guns of later generations.Ordinary guns are equipped with lead bullets the size of mung beans. It is very useful to hit a bird at a distance of 80 meters. The lethality is not small. seriously injured.

But if it hits the leg or something, the rabbit will still get away.

The later high-pressure guns can hit about 200 meters, and the effective range is about 120 meters.

Right now, I don't know how far this air pressure cannon can hit.

The guards opened the back cover and began to reload.

Li Yuanxing sat and watched from a distance. This is a rear-mounted type, and it is obvious that the flange is used, and then six iron buckles are added to fasten the flange. Four rubber rings are used for sealing, and then the flange is connected. Pressurized cylinders.

This steel cylinder is twice as long and about four times thicker than the one used to make popcorn.

The steel cylinder is not directly connected to the gun body, but placed on a shelf and connected by a flange.

"Your Highness, this cylinder can fire four times in a row!" Li Changying explained softly to Li Yuanxing.

Li Yuanxing remembered reading in a book that in Europe in the [-]th century, there was a prototype of **.Then it was equipped with the army in the seventeenth century, and there were also gas cylinders that could fire twenty lead bullets.

But that's a gun, it's a gas cannon.

"Write it down, let them study it, put the whole bottle of gas to burst out at once, and increase the strength. This is a cannon, it must have a range and power. If it is made small, then it will be fun to shoot continuously!" Li Yuanxing said , there was a guard next to him to quickly record it with a pen and paper.

Bai Erwa had already landed, her face was full of excitement.

"Since Erba, you like flying so much, you are allowed to recruit one hundred soldiers, one in a hundred." Li Yuanxing said lightly.

"Thank you, Your Highness!" Bai Erwa bowed heavily and stepped aside.

Li Yuanxing closed his eyes slightly, waiting for the air cannon to be launched. Finally, all the guards left the air cannon and stood on one side, bowing to wait for the order. Li Yuanxing slightly raised the fan in his hand, and then swung it down violently.

"Let go!" The guard in charge yelled, and then a guard yanked the cannon door forcefully.

Dare to test the cannon in front of Li Yuanxing, it means that he has gone through many tests and has enough confidence.Otherwise, Li Changying would not have rushed back to Qinwangzhuang overnight, so there was absolutely no possibility of failure.

With a muffled sound, Li Yuanxing felt the ground under his feet shaking.

The eight-foot-long gun barrel was still trembling slightly, a hundred feet away, there were already more than a dozen bamboo rafts.

I didn't even see clearly when it happened, those bamboo rafts were smashed to pieces.

"Max range?" Li Yuanxing asked.

"Your Highness, I haven't tested it, because there is not enough space in Yaozhou. During the test, I accidentally destroyed a workshop and injured several people. I originally wanted to test the cannon in the field, but the field was blown up. Money!" Li Changying already knew about the soap, so naturally he didn't want to destroy the land.

"Maximum lethality?" Li Yuanxing asked again.

Li Changying was very nervous: "Your Highness, I still haven't tested it!"

"Okay, don't be nervous. You rest for two days, and then conduct a comprehensive evaluation. Presumably you are eager to let me see this cannon, and I know your intentions!" Li Yuanxing was very gentle, which really moved Li Changying.

After reaching out to help Li Changying get up, Li Yuanxing said to Bai Erwa: "First, fill up the gas cylinder, I want to know how many days it can be stored. Second, call for the Chang'an West Camp, and ask the Security Department of the Tang Empire to arrange guards for three days. After the cannon test, I want to know all the data. Third, send someone to Yaozhou, and I want to know the power of this small steam engine. Fourth, block the news!"

After Li Yuanxing finished speaking, he turned and left.

After walking for a few steps, he stopped: "Fifth, you guys have a good rest today, but keep things in check!"

"Yes!" Bai Erwa bowed to obey the order.

After sending Li Changying back to the backyard and comforting Li Changying by his bedside, Li Yuanxing returned to the study.

In the study, Wu Zhao is sorting out all the materials of this year, and listing the detailed tables, preparing for a very detailed analysis.

"I need you to go to Yaozhou in person. This time it will take longer, at least a month."

Wu Zhao was stunned for a moment: "Did something happen in Yaozhou?"

"Yaozhou, they have made air guns, the principle is similar to air guns, but they also made two air guns, I will let you test it in three days, so you need to go to Yaozhou yourself, don't worry this time, look carefully at the problem gone."

Wu Zhao stood up, walked in front of Li Yuanxing, and gently took Li Yuanxing's hand: "This time, I will only watch and promise not to say anything."

"It's not that serious. Some basic knowledge of mathematics, physics, and chemistry can be considered to be taught. Make up your mind!"

Wu Zhao seemed to have some hesitation.

"Aren't you afraid that I'll make some trouble for you again?"

"No!" Li Yuanxing shook his head.

Squatting on the ground, she said to Wu Zhao: "My Li Yuanxing's woman is not in that beautiful vase, nor is my Li Yuanxing's answering person. She should have a reading mind. You take both Chunlan and Lanqiu. My only suggestion is Observe first, don't jump to conclusions!"

Wu Zhao's originally depressed expression was swept away: "I'm still very good!"

"That's right, otherwise I wouldn't worry about anyone going to Yaozhou. And I can't leave now!" Li Yuanxing praised him with no stinginess.

"I am excellent!"

"I know." After Li Yuanxing nodded, he said to Chunlan who was standing aside: "Take good care of Princess Mingyue in Yaozhou, and I will reward you when you come back!" (To be continued.)
