[This is a basic update, this is not a plus, but the first update of the second update]

The hurried knock on the door woke up Li Yuanxing, who was still in a dream, and with the help of Cui Yingying, he finally pushed the octopus-like Zheng Xiuyan aside.

The maid Ying'er ran to open the door, and it was Lan Qiu, who was on duty tonight, who knocked on the door.

"Report to Your Highness quickly, Princess Ying rushed back from Yaozhou by light car, less than five miles away from Qinwangzhuang." Lan Qiu said anxiously.

Li Changying rushed back in the middle of the night, something must have happened, Cui Yingying hurriedly helped Li Yuanxing get dressed.

"I want candy!" Zheng Xiuyan is still talking in her dreams.

Cui Yingying helped Li Yuanxing get dressed, and asked in a low voice, "Why did Your Highness get close to Xiuyan last night?" ”

"She's still young, let's go in another half a year." Li Yuanxing said softly, then reached out to help Zheng Xiuyan put her arm back into the thin quilt, and helped Cui Yingying put on her coat: "It's cold in the morning, don't get cold." Arrange it, prepare hot water, and have some snacks, Changying rushed back in a hurry, it must be very hard! ”

Cui Yingying nodded, which was acceptable.

In front of Qin Wangzhuang, Li Changying did not feel too tired to move, but an extremely excited look. Even Bai Erwa's eyes were shining brightly.

"Congratulations to Your Highness, congratulations to Your Highness!" Li Changying was so excited that he didn't know how to express it, and hurriedly walked towards Li Yuanxing.

Li Yuanxing stretched out his hand and hugged Li Changying, who was about to give a salute, and then said to Bai Erwa: "Tell this king why he came back in such a hurry." ”

"Your Highness, we've made that artifact of yours!"

"Artifact?" Li Yuanxing was taken aback. Then he asked, "What artifact?" ”

"It's the artifact you used against Luo Yi's two subordinates." Bai Erwa has seen Li Yuanxing use heavy spraying. He still remembered the terrifying feeling in his heart at that time.

Li Yuanxingxin said that the shotgun, which is an anti-heaven thing, is actually made, so you must see it.

"Martial arts arena!" Li Yuanxing ordered in a deep voice, and Bai Erwa straightened her waist: "Get the order!" Bai Erwa took people to the martial arts arena, and Lu Maofeng was naturally responsible for calling people to be vigilant.

Li Yuanxing said to Li Changying at this time: "How about going back and resting first?" ”

"I'm not tired, I want to accompany Your Highness!" Li Changying actually couldn't even open his eyes, but he held on.

"Okay, let's go!" Li Yuanxing's right arm couldn't be strengthened, so he could only help Li Changying to sit in his soft sedan chair, but Li Changying asked to take Li Yuanxing to walk to the martial arts arena together.

What's pulled in the car?

Li Yuanxing was also very curious. Because that huge iron box has a very magical feeling.

Then. The sound of the time machine ticking shocked Li Yuanxing's heart.

It's a reminder that the contents of that box may be the key to four times as much time, isn't it? Will there be a miracle there?

Li Yuanxing couldn't help but speed up his pace.

The arena has been sealed. This is Qinwangzhuang. It can be done to a level of vigilance that is no less than that of the forbidden courtyard of the imperial palace.

When Li Yuanxing came to the martial arts arena, the seats had already been set up here, and several guards were placing straw figures there. In addition, there were several guards who went to carry water, and some went to pull coal.

When the iron box was fully opened, Li Yuanxing stood up violently.

That was a steam engine, a small steam engine.

But from a structural point of view, it should be a multi-rise type. And the boiler is pure steel, which is riveted. From the interface, the steel plate is very thick, but I don't know how to deal with the sealing problem.

"Your Highness, they add pure water, which is water that is steamed in the way that His Highness taught." Li Changying introduced on the side.

Li Yuanxing's head is already a little dizzy, this is not scientific, this is absolutely unscientific.

Such a thing seems to exist theoretically, but it has been applied in cartoons in later generations, but no one has done it at all when it is really put into modern science, which is really extremely unscientific.

The fire was already lit and the steam engine began to pressurize. Li Yuanxing was surprised to find that there was a sentry next to the boiler. In the process of pressurizing the boiler, the guards in charge of the operation would press the platoon whistle from time to time, at first one whistle with a slight sound, then two, three.

There is no pressure gauge, so I use this way to test the pressure.

Datang, the world really underestimates the craftsmen of Datang, they are crazy and don't know how many geniuses there will be.

Li Yuanxing was right, the craftsmen of the Tang Dynasty had been suppressed for too long.

In Yaozhou, they have status, status, and every family of craftsmen above the fourth rank has slaves, and each of them has at least ten slave helpers, and they already feel like they are people with status.

What's more, Yaozhou gave them a chance to go crazy.

Any whimsical idea, as long as you can come up with enough theoretical support, it is possible to prototype it.

When the eighth whistle sounded, Li Yuanxing saw that a guard had opened the valve, and a column-mounted pure copper pipe began to be continuously poured into the air.

This is not steam, but liliang, which uses a steam engine, to forcibly compress the air.

"Your Highness, a hundred zhang!" Bai Erwa took a telescope and handed it to Li Yuanxing with respectful hands.

Li Yuanxing nodded slightly and took the telescope.

A hundred zhang away, which is the modern 300 meters, there is a straw man. Next, the guard opened the back cover of a copper pipe and filled it with a paper bag.

"Refill!" Li Yuanxing was really taken aback.

You have to know how many years it took for the musket to make progress from the appearance of the musket to the real reload. But these guys in Datang turned out to be post-filling from the beginning, and I really don't know how this process was completed.

"How was that brass done?" Li Yuanxing asked casually.

What made Li Yuanxing even more surprised was that it was Li Changying who replied: "Your Highness, at the beginning, the craftsman rolled out a copper pipe with a steel plate, but in fact he couldn't bear the pressure. Later, I chose to cast, but what was cast was trachoma. The final solution is to use a piece of steel and then drill a hole in the middle. ”

"Drill holes! How much work does it take? Li Yuanxing continued to ask.

"The hydraulic drilling machine is not good, it is not stable enough. The steam engine drilling machine requires a third-class craftsman to get started in person, drilling in one day, and polishing the inner wall in one day. The cost of making such a piece is calculated to be 800 yuan. The concubine has already ordered that if it can be reduced to one hundred dollars, there will be a heavy reward! ”

Li Yuanxing nodded with satisfaction: "There is no need to be too anxious about this matter, with the improvement of the process, the cost will naturally be reduced!" ”

At this time, Bai Erwa shouted over there: "Your Highness, it's ready." ”

"Let's get started!" Li Yuanxing picked up the binoculars.

I only heard a bang, and the straw man was beaten to pieces.

Li Yuanxing sat still and didn't move, and a few guards ran over, some carried straw men, and some ran over with a bullet.

Straw men are naturally not sturdy, because they use hollow buckshot, the size of a peanut. Because it's air, this one is lightweight and hits far enough.

"The farthest, how far can it be?" Li Yuanxing seemed to ask casually, but in fact, there was already a kind of fanatical excitement in his heart. The craftsmen of Datang are crazy, this is the principle of air guns in later generations, who would have thought that they would actually make them.

"If you go back to Your Highness, you can reach up to three hundred zhang, but you don't have the right head."

Li Changying said next to him: "Your Highness, the concubine has ordered them to study the cannons, if there are a hundred or hundreds of such guns, and they are fired at the same time." Even if you don't have the right head, you can suppress the enemy cavalry at a distance of three hundred paces. It's just that the number of steam engines needed is huge, and this must be improved. ”

Awesome!

Li Yuanxing sincerely said a word.

But then, something even more amazing was lifted.

It's not a gun, it's a real cannon, the barrel is thick, and the air pressure tank at the back is a spherical one. That's the size of a person.

"Your Highness, this will take a quarter of an hour to use." Li Changying introduced on the side.

"Tell me to go down and wait for breakfast." Li Yuanxing sat back in his chair, he was no longer shocked in his heart, Li Yuanxing even felt that he had influenced Datang with black technology, but Datang had taken black technology to the extreme. Something that only appeared in later cartoons, science fiction films.

Evil, so evil!

The evil sect has reached the evil sect that Li Yuanxing can't imagine at all, and it has only been three months. Li Yuanxing was thinking about what kind of drawings Wu Cao gave to the craftsmen in Yaozhou, or what kind of jihua he gave.

The breakfast became tasteless, and Li Yuanxing's mind was all in the whistle of the steam engine.

"Your Highness, there is one more good thing. It's just that this thing can't be considered a finished product, and the craftsmen think that there are still too many things to improve. And they didn't fully understand the principle, so they just copied one, and when the cannon was inflated, it would be better for His Highness to take a look at that thing first. The concubine likes it very much, and it is also the concubine who advocates that they make it, please take a look at it Your Highness, and make a comment or two! Li Changying's tone was suppressed excitement.

Li Yuanxing was no longer surprised, even if anything came out now, it would not surprise Li Yuanxing.

Another box was opened, and Li Yuanxing only looked at one of the things here, and he knew what it was.

Glider, this is a glider made by Datang craftsmen, the material should be based on bamboo, silk, linen, glue made of the skeleton, and then with silk, linen woven cloth, and then coated with glue as a wing cloth used. However, Li Yuanxing couldn't figure out what the two shelves next to him were, but Li Yuanxing believed that the craftsmen of the Tang Dynasty would never add useless things.

Bai Erwa jumped out, he wanted to test fly in person.

Ever since they saw His Royal Highness King Qin flying over Luoyang, these guards had dreamed of letting themselves fly.

Right now, Bai Erwa is about to fly up in front of His Royal Highness King Qin. (To be continued......)

PS: Come on.
