The advent of diesel internal combustion engines can make the power unit not have to be as large as a steam engine like Meng Bao, and it also greatly reduces its own weight. This laid an important foundation for the development of automobiles and aviation.

However, before the racing race had even started, the student's tricycle withdrew from the race. The reason is, his car blew out. Because he didn't have any cooling equipment installed. It only depends on the external environment to cool down. At the same time, he drove his car too fast to show off. Outcome. Naturally, the car bursts.

However, his race car and his name remained in the newspapers.

"Chen Tong and His Racing Car" and "Financial Express" interviewed him. And he gave a detailed description of his diesel internal combustion engine. Journalists don't know the value of the internal combustion engine, but they do. The machine was much lighter than the bulky steam engine.

People are just talking about this story. It's like a daily weather forecast. Sometimes, the weather forecast can be predicted very accurately, but sometimes it is pure nonsense, especially what temperature gauge. With the war of a large number of experiments, especially the air pressure experiment. Some researchers have already developed thermometers. But they call it a temperature gauge.

The emergence of the internal combustion engine has attracted the attention of relevant scientific researchers. In particular, the Celestial Forces were concerned about the urgent need for a power plant smaller than the steam engine, and the advent of the internal combustion engine undoubtedly provided them with support in this regard. Therefore, the Celestial Army is very concerned about this technology.

You must know that at this time, there was no newspaper or magazine in the Qin State that specialized in reporting on science and technology and research results. In terms of academic communication, technical personnel only communicate internally. Scientific and technological resources are unusually dispersed. This was very detrimental to the scientific development of the Qin State.

Racing led to a new invention, the internal combustion engine. This is good news for Shangwen. But now he can't take care of this new invention. Because, he needs to negotiate. Negotiate with Li Mu.

A few days after Li Mu arrived. He was successively received by the King of Qin, Wei Yi and other important ministers of the Qin State. This made it difficult to divert energy to look at other changes in the Qin state. However, for the conditions proposed by Shang Wen, he felt that it was better to be careful.

"General, we understand what we mean. Our relationship is to hire your army to defeat the Xiongnu and Hu people in the north, and the new minority we have discovered, the mountain people. Shang Wen said as he sat on the other side of the negotiation table.

The group led by Li Mu sat in a classroom at the Army Military Academy with some civilian officials such as Shang Wen and Wei Yu. The conference table, which was improvised from the desks, looked a little uneven. It's like a relationship between two parties. There are a number of areas where the two countries need to build trust.

"Sending troops out is not a trivial matter. Prime minister. Li Mu said. Li Mu still didn't understand what the other party was trying to do. Obviously, Li Mu was very cautious.

"General, the cold winter in the north is coming. This is not a good thing for you, your treasury is out of money. There is not much food either. And the amount of money in us is too much to count. Food, we don't need much. Our soldiers on the front line can solve the logistical supply of the army on the spot. Our newly established states have built a lot of food factories, and the shelf life of meat is enough for them to stock up on large quantities of food. These are things you can't imagine. Shang Wen said slowly. Li Mu admitted that this fact occurred in the Qin state. And it does. The strength of the Qin State has far surpassed that of the Six Kingdoms. Take meat processing, for example. Li Mu saw that there was a kind of machine in the Qin State, as long as the meat pieces were put in, it could be turned into meat puree, and it could become very fine as long as it was repeated once or twice. In Zhao State, such a large piece of meat requires many people to process it for several hours. The power of machinery made Li Mu see again that manpower could no longer be compared with mechanical power. And the state of Qin precisely mastered this mechanical force. That's strength.

"The population of Qin is not very large, and although we stopped the war, the scale of the population demand is still very large. Especially in some labor positions. We lack a large number of personnel. Shang Wen said.

"Don't you have slaves? A large number of prisoners of war slaves. Li Mu emphasized.

"Prisoners of war slaves are people who cannot be trusted. I have ordered to encourage slaves from the north and the west to concentrate on the south of Guanzhong, and concentrate on the construction of a network of trains and roads to Bashu. These people must leave their homes. Have to. Shang Wen is very clear on this issue. The foundation of a nation's culture is the land. If you leave the original land. Their culture and civilization will become unstable. And their national stability will become very fragile. Or be wiped out. Or assimilated by other civilizations. Shangwen did not want to see a powerful civilization become a neighbor of the Qin State.

"Why?" Li Mu asked puzzled. The content of the negotiations is going off track. Li Mu deliberately figured out the other party's intentions.

"It's like a pot of flowers." Shang Wen made a very vivid analogy.

"Flowers?" Li Mu asked.

"Yes." Shang Wen returned to the road.

"A pot of flowers grows beautifully, mainly because the soil in the pot provides a lot of nutrients for it. Blooms through their own photosynthesis. Shang Wen said. Although Li Mu didn't know what photosynthesis was. But the metaphor is really vivid. He already understood why Shang Wen was doing this.

"If you pull the pot out. Then the flowers on it will lose nutrients. If you replace it with a flower pot. It takes time for him to get used to it. Such frequent replacements. Flowers, either die or become something else. Shang Wen said.

"So is Zhao Guo's army like this?" Li Mu asked.

"It's like that flower. Move around, move over. Li Mu asked.

"No, it won't. We removed the original flower and planted a seed of our own. Shang Wen said.

"In fact, you have no choice. Maybe we can do it another way, and don't want your army. Let our people in, and let your people freely participate. In short, you have to solve the problem of feeding a large number of people. If you stay where you are and rely on the Qin State for help. That's impossible. The Qin people donated very little money to the Zhao people. Only a few people are involved and your businessmen donate. And. We can't afford to pay for the disasters that have befallen you. That's impossible. And it's not a long-term solution. If not. Your people are going to be in a big predicament. When we are Buddhas, there is nothing we can do. Shang Wen waved his hand and said.
