When Li Yuanying received the news from Li Shimin, his whole person was not good...... The tenders actually want to be the Tang version of Tudanke! The tenders let go of themselves, and they are too wild...... Su Daqiang is not as wild as you!

Archimedes did say that if you give me a fulcrum, I will pry up the whole earth. But that's just an exaggerated rhetorical device, and there is more than one fulcrum used in the wandering earth, and it was almost taken over by Jupiter.

You can understand everything from fireworks to artillery, but ...... The steam car crossed over to Tudanke, who of us crossed over?

"Lord Wang, it shouldn't be very difficult to transform that kind of car." Du Che saw that Li Yuanying had been in a daze, took the note in his hand, and said with some puzzlement after reading the news. The crossbows were mounted on steam carts, the arrows carried gunpowder packets, and the wheels were modified to fit dirt roads, meadows, and even deserts...... Could it be that the prince is thinking further?

Li Yuanying shook his head and muttered in a low voice: "The tiger is out of the sheng, and the turtle jade is destroyed in the coffin, whose fault is it?" ”

When Pandora's box was opened, it was confronted with more than just Fanbang...... I am afraid that Ji Sun's worries are not in the moment, but within the Xiao wall. They walked much faster than one had originally thought, and did not have enough time to lay out the three sets of carriages. The two sets of carriages of the family and the nobles no longer have any resistance in front of the royal family or the political hall headed by the emperor. The struggle within one or two hundred years will become just a heavy cake within the Li family.

Unless the Tang Dynasty also likes to dance in the palm of his hand, the emperor of the thirty-sixth palace has a long autumn night, for the sake of beauty, the colored hat can endure it, and even his own flesh and blood can be thrown to the ground. Needless to say, I thought that the world and Wei Xuanzhen were in such a fuss, and he didn't agree to make the emperor's daughter. Because whether it is the world and Wei Xuanzhen, or when the Qing wants, the prohibition comes from the pen of the old man who likes to smash the cylinder.

The little girl in history, under the pen of the elder, is dressed up in line with his aesthetics, and Xu Jingzong's little means of cultivating history is not even qualified to be a younger brother in front of him.

One or two hundred years later, there will be a few more amazing geniuses among the people, and a few more faint monarchs will relax the restrictions on minerals, and there may be a situation where they will be cured by the house.

There must be a law that states that people are not allowed to possess wallpaper. Because the flowers of freedom are blooming everywhere, flower growers don't need them.

"Lord Wang, what are you talking about?" Du Che didn't hear Li Yuanying's words clearly, only heard whose fault it was.

Li Yuanying came back to his senses and said with a smile: "It's okay, I'm just thinking about how to improve Jiannu." ”

The fuel engine that Tudanke needs has not yet appeared, as long as Gongsun Bai can refine tungsten, the wallpaper can go first, "How is the situation with Mr. Gongsun?" ”

I don't want to make a wall that will blow up, and I don't want to make an arquebus, it's easy to use it in a hurry, and the range is short. It took three or four hundred years to match the rifling and the eggs, as well as the improvement of the rifling, until the diameter of the Miner egg was one circle smaller than the diameter of the rifling of the male wire, and the problem of loading difficulties was solved. The biggest improvement is a small conical hole at the bottom. When fired, the gunpowder gas expands the tail, embeds in the rifling, and rotates at high speed with the rifling to unchamber.

It can only be said that it is a small step forward for the eggs, and a big step forward for people.

As for the degree of rotation of the back and forth line, the length of the wall pipe, and the choice of material, it is necessary to not only be hard and tough, but also resistant to compression and high temperature...... Leave it to Du Che and them to solve.

A small step forward, and the remaining big step needs to be taken away by Yunhe Mansion.

Standing on the shoulders of giants and looking down, you will find that the solution to the problem is simple. But if you stand at the foot of the mountain and look up, the majestic mountain is high and you can't climb it. Brother, why is their brain hole so big? It's not scientific!

"Li Shangshu helped bring a few pieces back to Gong Wei." Du Che looked at him left and right, and resolutely did not mention Gongsun Bai's head, a certain ...... A certain person is also a person who wants to face.

Li Yuanying patted Du Che on the shoulder, and walked towards the backyard without saying anything. Jinyang Xiaobaozi just came, always have to take her around, not to mention that today's working hours are exceeded, the work intensity is seriously exceeded, and she has to recuperate for five days.

If Gongsun Bai doesn't have any results after five days, he still has a good time playing with flying swords, and he can also draw talismans to help make a rainy cloud, or let the first snow in the twelfth year of Zhenguan come a little earlier.

Du Che wanted to shrink his neck, but when he remembered that it was not the time when every hexagram was a big murderer, his back was straighter, and he ...... A certain is now Teng Wangyou, and he hasn't counted a hexagram for almost two months, or is it a hexagram for Yuan Gong?

Someone who said he would do it, after half an hour, threw the turtle shell in his hand into the stove where the water was boiling, the copper coin withdrew his sleeve, and left the study with a flutter.

Yuan Tiangang, who was sitting on a futon in a thatched hut somewhere in Lushan, opened his eyes and looked in the direction of Xicheng, the corners of his mouth rose slightly, and he said in a low voice: "Shaft." ”

"Master, what do you command?" The Taoist boy in a blue robe stretched out his head curiously from outside the door and asked.

"Mingyue, go to the kettle of water, soak in the pot of fresh breeze and freshly fried Lushan Qing." Yuan Tiangang shook off the dust lightly and said. According to the biography of Nanshi Xie Yi, sometimes he was drunk and said: Those who enter my room, but there is a breeze; To my drinkers, only when the moon shines. The Xie family, the tenth prime minister, has dispersed into the bright moon with the breeze. When the previous dynasty destroyed Chen, it was almost a lonely and cold clan, and it was never heard of in Tang Li.

"Whoa." Mingyue answered, turned around and ran away.

Yuan Tiangang stood up, came to the courtyard, looked at someone who was coming from afar, and said with a smile: "Aren't you refining ore?" ”

There are new swords entering the pool every year, don't want to use some nonsense of 'not as good as Wei Hei Dog' to make people in the lake.

"Do you remember the sesame seeds in Du Si's hand (chapter 178)?" Gongsun Bai put away his sword and looked at Yuan Tiangang with a serious face, but his eyes were extremely complicated, and under the mixture of joy and sorrow, with a hint of apprehension, he asked softly.

Yuan Tiangang's eyes turned slightly, his face became serious, and he asked solemnly, "How many?" ”

Gongsun Bai took out a piece of silver-white metal from his sleeve, about the size of his fist, and said: "The two pieces of ore are refined, which is lighter than the metal found in Chang'an that does not change color and is jokingly called platinum by King Teng, but the melting point is much higher, and you need to use your fingertips to melt it." ”

Yuan Tiangang took the metal from Gongsun Bai's hand, gently rubbed it with his fingers, and asked, "What does it look like just after refining?" ”

With such a high melting point, how do ordinary craftsmen deal with it? King Teng was originally very interested in sesame seeds, and if he knew that they could not be used by Shaofu craftsmen, he would be very ...... Heartbroken, and the way he behaves sadly, somehow not interested at all.

"Powder, irritating to the eyes and skin, slightly toxic." Gongsun Bai explained softly.

Yuan Tiangang breathed a sigh of relief, there was a lot of room for operation in the powder form......
