Li Jun said it very tactfully. Huang Yongshan knew the weight of it and hurriedly said, "The emperor is wise, please let the emperor make it clear."

"We are discussing technology, don't mention these." Li Jun pulled Huang Yongshan with his left hand and Zhang Chaoxuan with his right hand back to Huang Yongshan's room, pointing to the drawings and said: "Steam is cooled in the cylinder, which is low in efficiency and also wastes heat energy. Make a separation condenser outside the cylinder, connect the steam with a pipe, and cool it in the separation condenser, and the efficiency will be much higher."

Huang Yongshan's eyes glowed, he patted his forehead and said, "Why didn't I think of it? This is a good idea."

Li Jun continued: "The linear motion of the piston is inconvenient. You can design a gear linkage to transform the linear motion into a circular motion. Then install a flywheel, and it can be easily driven."

With a "bang", Huang Yongshan slapped himself hard and said, "I'm so stupid."

"You are already very smart. This is an idea that Watt thought of after decades of research. How could you, an ancient man, think of these things in a short time?" Li Jun praised Huang Yongshan in his heart and said, "Steam enters from one end, with very low efficiency. It can enter from both ends, and the piston can work when it goes back and forth."

Huang Yongshan stomped his feet and said, "This is a very simple method. Why can't I always think of it?"

"Simple? This thing seems simple, but it is actually complicated. Otherwise, Watt wouldn't have taken so much time to complete the improvement." Li Jun complained to the scientist a little, and said: "You can also combine the flywheel, gear linkage and cylinder."

Li Jun said and gestured. Huang Yongshan felt like he was trying to clear the clouds and mist and saw the blue sky. He jumped up excitedly and said, "This is simply amazing. Your Majesty, you are really amazing. A few words can withstand my decades of hard work."

These are the four patents Watt obtained for the four improvements made by Newcomer steam engine.

Li Jun pointed out: "As for sealing, just use asbestos rope to plug it in."

Speaking of asbestos rope, some people may think that it is a product of modern society. In fact, it is a traditional product. That is, the "fire-washing cloth" mentioned in ancient Chinese books was used in the Spring and Autumn Period and the Warring States Period. For the Song people, this was not a difficult task at all. Before there is no better sealing technology, choosing ready-made technology is also a good choice. (Note: As far as I know, in chemical production, the sealing of heated places uses asbestos products instead of rubber, because rubber is prone to aging after heating.)

"What's so magical about this? Watt's steam engine has been sealed in history. Now society has long been in the era of electricity. If you want to see Watt's steam engine, you can only enter the museum." Li Jun laughed in his heart and said, "The production of steam engines is very complicated. If Master Zhang carved it one by one, it would not be a solution."

Zhang Chaoxuan is a honest person and did not hear what Li Jun said, and hurriedly said, "The people in the grass are incompetent, please punish the emperor."

Huang Yongshan poked him gently and said, "This is not what the emperor means. Master, what are you going to do?"

"We use a lot of steam engines. Even if we carve one, what should we do if we carve it? If we carve one by one, we don't know when it will take to meet our requirements." Li Jun analyzed and said, "I'll draw a drawing for you. Master Zhang carved it according to the drawings and assembled this machine, and producing steam engines will be much faster."

Huang Yongshan hurriedly laid the paper, and Li Jun picked up the pen and drew it. After drawing it, he put the pen on the pen holder and said, "This thing is called a machine tool. It can be equipped with a tool to turn and mill. It is much more convenient and efficient. That's it. Before this power is solved, it's still the same way to drive the donkey."

Huang Yongshan and Zhang Chaoxuan looked at the desk carefully, and the expressions on their faces changed. After reading them, Huang Yongshan applauded and said, "It's a masterpiece of ingenuity."

Zhang Chaoxuan is not good at expressing words and nods to agree.

Wen Tianxiang and the others came over to look at the lines on the paper, with a little big head, so it was unclear.

"What a clever craft? If this kind of old machine tool is also a masterpiece, what is the CNC machine tool in modern society?" Li Jun held back his funny and said, "This first one will be carved out by Master Zhang, and the ones that will be produced later will be produced by machine tools."

Huang Yongshan pointed his head straight and said, "Yes, yes, that's really right."

Although Gundam did not understand technology, he knew that there was something good again when he saw Li Jun and the ministers excitedly. He said to Huang Yongshan happily: "You guy has been nagging that there is not enough people. Now that the problem has been solved, you have to produce more equipment for me. The equipment you produce can only be equipped with a small part of the army. If this continues, I will ask you guy to use your neck to block the Tartar's scimitar."

"That's not my fault, it's the truth." Huang Yongshan cried in his heart and said, "Don't worry, General Gao, I also want to give birth earlier and drive the Tartars away, and also make the ears quiet. The cats and donkeys are croaking all day long, which is unbearable."

"It's good that you know." Gundam did not forget to threaten Huang Yongshan and praised: "But, you guys are really a bit better than the Buber, who always loves to brag. The Tartars only know how good he is, and he is the best in making cannons, and he has no real ability at all." He kept his lips curling, looking down on Buber very much.

Li Jun was a little curious and asked, "General Gao, what did Buber say?"

"The Tartars brag all the time and yelled that they were experts in artillery making. No one in the world could compare to him. How good the artillery he made was, it would be killed for us." Gundam said very disdainfully.

"Buber is right. He is indeed an artillery expert. Otherwise, how could Xiangyang take it down?" Li Jun thought so in his heart. He looked at Huang Yongshan, but he saw that he didn't agree with Gundam. Li Jun was so wise in his heart that Huang Yongshan knew that Buber had real talents and knowledge.

In modern society, countries have sharpened their heads to obtain advanced technology from other countries, and the United States is even more shameless. At the end of World War II, they obtained more than 80% of Germany's advanced technology. The famous Dr. Qian Xuesen and his teacher Feng Carmen interrogated his master, a famous German swept-wing aircraft designer.

Although Huang Yongshan, a technical expert, was not greedy, he naturally had to go to meet him after hearing Buber's words and deeds. Li Jun was not surprised and asked Huang Yongshan: "What did Buber say?"

"Return to the emperor, Buber said that he is an excellent artillery expert and there is no artillery that he cannot make." Huang Yongshan shook his head slightly and said, "He also wanted to bet with me, saying that if I win him, he would be willing to assist me in making artillery, and if I lose, I will let him go. He is already our prisoner. This is a false statement, and I did not agree."

"It's useless if you agree, and the decision is not up to you." Li Jun felt a little dissatisfied with Huang Yongshan's statement and asked, "How are Buber doing these days?" Since he captured Buber, Li Jun has been busy commanding the war and has long forgotten this historical celebrity. If Gundam hadn't mentioned it, he wouldn't have known that it was the Year of the Monkey and Horse Month when he remembered it.

Gundam said, "What else can you do? Go to the prison, put two bowls of pig food, and raise them like pigs. This Tartar cannot feed him, and they are yelling all day long, saying that he is the best artillery expert, which is so annoying."

"These semen are so arrogant when they become prisoners. They are yelling everywhere with their skills that are not collected by the history museum. They really think that China is no one else, and he can't cure him if he doesn't give him some power." Li Jun thought in his heart angrily, saying, "The capture of Xiangyang has a direct relationship with him. If they hadn't built Huihuan, Xiangyang wouldn't have fallen. We have to calculate this. Don't take advantage of him if he falls into our hands. Find a few jailers with black hands and serve him well. If you have any good ideas, just greet him, the more ruthless the better."

Everything started from Xiangyang, so the fall of Xiangyang was an eternal pain in the hearts of the Song people. Wen Tianxiang and the others remained silent and looked sad and angry.

Gundam agreed loudly and said, "Now, this Tartar has a good time. This Tartar is very noisy, so it's time to give him some excitement."

"Don't worry, the jailer's hands are very dark, and it's very convenient to find them." Wen Tianxiang received the order.

Li Jun was very angry about the Semi people helping the Mongolians to build cannons to attack the Han people's cities and often said: "These Semi people are really forgetful of their power. What kind of grudge does the Chinese have against him? How can he create such a powerful weapon?" Buber shouted, and it would be strange if he hit him and he would not suffer any loss.
