Chapter 198: Letters from the north

Shang Wen had a lot of discussions with the old man Wei, and finally reached a consensus, that is, Shang Wen should set aside at least five thousand dollars to establish medical schools, hospitals, medical teams, and provide certain technical support. The old man Wei must ensure that a large number of medical personnel are trained and hospitals are established. Served as the head of the medical school.

Shang Wen did not hesitate to agree to this condition. Five thousand dollars can basically establish two large gun factories, but compared to saving people, Shang Wen thinks it is worthwhile, because the establishment of hospitals also has an important guarantee system, which is a modern medical level. The far-reaching significance of improving the medical and health standards of this era is extraordinary.

First of all, it benefits from the substantial increase in human life span. Then the birth death rate will plummet. And these effects are accompanied by many other effects, and these effects need to be slowly integrated.

Later, Shang Wen and Old Man Wei left in a carriage. The musket regiment was not under their own jurisdiction. If they said too much, they might go beyond their authority. Moreover, he is a civil official, and he can manage the heavenly army within his jurisdiction, but he has to go beyond his authority if he wants to manage the affairs of the army. Shangwen still knows something like this.

But it was Tu Sui who was disappointed. Originally, I had the opportunity to ask a little bit about the details of gun warfare from the right of Da Qin, or some other suggestions, it is better to have some novel equipment. However, they seem to be very busy, and there is no time to take care of themselves.

Shangwen is indeed very busy. All the work at hand has been transferred to Meng Yi. Meng Yi set up an office in an inn in the city of Xianyang. Shangwen did not remember the specific place. He just knew that an office was set up there. People, Meng Yi is mobilizing around, and there is no official office yet, and Meng Yi can only take one step at a time. Because Meng Yi didn't know what exactly this rightist was up to.

"By the way, my lord, here is a letter from the Guyang Iron Factory in the north." Meng Yi reported on some of his work, while Shang Wen was doing some electrical experiments in a hurry.

Shangwen uses a generator to generate a certain amount of current. With electric current, a machine that converts electric current into mechanical energy is needed. This is an electric motor. Shangwen agreed with one mind and two purposes.

"Oh." Shang Wen agreed. The motor uses the energized coil (that is, the stator winding) to generate a rotating magnetic field and act on the rotor to form a magneto-electric power rotating torque. To put it bluntly, the motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic line of induction (the direction of the magnetic field). The working principle of the motor is the action of the magnetic field on the force of the current to make the motor rotate.

With the principle of these generators, it is easy to make a motor because the materials are stored here, so there is no need to collect a lot of materials. Moreover, some things can be processed by themselves, and this is a simple experiment, which is mainly a positive experiment result. If it is processed, it takes a lot of attention. Shang Wen paid attention to the experiment result entirely, and did not notice what Meng Yi said.

The motor made by Shangwen is very simple, and the principle can be understood with a little explanation. This is very similar to the world's first electric motor. But this is the first electric motor of this era. Although a little crude, it is the father of electric motors in the future.

"En, what did you say." Shang Wen asked, setting up the generator's device, and then connecting the wires together. All wires are exposed, without any insulation material. That's because the insulating materials come from tropical or subtropical regions, and there is no such latitude zone in Qin. Even so, the Qin State is actively expanding eastward, and has no intention of developing southward. If the strategic direction cannot be changed, many things cannot be manufactured. Shangwen had long wanted to attack the South, especially the idea of ​​letting the war of unification give way to the war of resources more than once. The industry needed a lot of raw materials to process, but the geographical location of Qin was quite lacking in these things. If it is Chu State, Shang Wen thinks it is nothing, but this is Qin State and there is no outlet for sea. Yes, there is only a large amount of land. These have restricted the development of industry. Next, Shangwen intends to tell King Qin to open up a war in the south. The army will not invest much, as long as 10,000 to 20,000. The most important thing is to adopt step by step means to provoke a war between the barbarians in exchange and purchase. In exchange for a large number of Vietnamese slaves, at the same time, the Qin army sent a small group of troops to participate in it, or formed a large number of mercenaries to participate in it, and gradually controlled the South in the hands of Qin.

To control the barbarian. Launching a slave war is the most effective control method, and it is also very thorough. In this way, it can completely solve the problems of ethnic minorities that have not been resolved for thousands of years. This time, these ethnic minorities will be completely raised from their native land. Clear the land. Unlike later generations that use a large-scale army to carry out encirclement and suppression, if the encirclement and suppression fails, they will be comforted. This is an extremely wrong approach, and it is very one-sided. What Shangwen wants to solve is a fundamental solution. The purpose of uncompromising and non-negotiating measures against ethnic minorities is to severely crack down on them. They drastically reduced their population, annexed their lands, and provoked wars between tribes. The population reduction of a nation means cutting the branches of a big tree and annexing their land, which means that the root of the big tree loses contact with the soil. If the root loses the soil, there will be no nutrients. Over time, it will wither and become a piece of rotten wood, and then do whatever you want.

This method is a bit slow, but it is very thorough. As long as it is fully implemented, within a year, Qin's territory will be able to expand to two counties. Thinking of this, Shang Wen began to make a preliminary estimate. If this is the case, it will take at least two years to reach the subtropical region, and the time is still a bit slow. This is really a big blow to the industry. Shang Wen's hand did not touch the wire, and his hand was a little numb, but fortunately the voltage was not very high. But Shang Wen was a little anxious. This speed is still very slow. If the army is used, it will seriously interfere with Qin's overall strategic plan, and Shangwen can only find another way.

"My lord, this northern letter." Meng Yi reminded again.

"What." Shang Wen said slowly after God.

Meng Yi pointed to a wooden board in his hand.

\"Oh, sorry. I'm distracted." Shang Wen waved his hand, and then turned out that Qin's font on Meng Yi's wooden board was too difficult to understand. This letter came from the North Guyang Iron Factory.

The content of the letter roughly states that the iron factory's iron has kept up with the huge demand, and now more than 70% of the original stored iron ingots have been used. The situation is very urgent. Urgently need my own help.
