The breakthrough in agricultural technology did not stop there, they invented soilless cultivation technology in greenhouses. This technology will greatly improve the yield and quality of agricultural cultivation in the Qin State. At the same time, it is also conducive to the generation of new seeds.

Soilless cultivation technology is derived from the reaction of chemical solvents. The chemical industry of the Qin State developed rapidly, and many new reagents continued to appear. And most of them come from solution reactions. This provides a reference for the farmer. So can the cultivation of crops be carried out in solution, so they start by putting the plants in water. Add a variety of nutrients to the book. It is mainly extracted from the urine of the nutrient solution. It is mainly supplemented by nitrogen. As a result, they discovered the benefits of water cultivation, and gradually turned their attention to the extraction of soil nutrients. This is the extraction of the initial nutrient solution.

In addition to nitrogen supplementation, they also invented the use of chemical fertilizers. It is still a chemical component extracted from urine. This invention will be the first to the advent of chemical fertilizers.

However, the chemical side did not pay attention to the use of agricultural fertilizers, and with the widespread use of nitric acid in the Qin state. The production of nitric acid is on the agenda. Although the Qin State is rich in mineral resources, there is a growing demand for nitric acid. Mainly for the production of detonators, smokeless gunpowder needs. Chemists are exploring a new way to easily obtain new nitric acid. And this method relies on new forces. Molecular Theory. The emergence of this theory will make chemistry a big step forward.

The major breakthrough in the Qin state's achievements stemmed from Shangwen's allocation of one-third of government spending on education, and the Qin state not only built universities and basic education facilities in Guanzhong, but also established state universities and a series of basic education in various newly established states. Basic education is free of charge. University education requires its own teaching costs, and if you don't want to, you can sign talent training agreements with a series of companies, so that most of the tuition fees can be waived whenever new inventions appear, and if possible, mainly because the technology is widely used. It is likely to earn a batch. This approach comes first from technical colleges and universities funded by large corporations. They are the workhorses of the technology push.

In terms of school system, the school system of the Qin State was relatively chaotic. There is no uniform regulation yet. Mainly, the training of a college student, especially a technician, comes from his research results, and this pragmatic approach will directly lead to the chaos of the Qin academic system, first of all, becoming a professor comes from whether your research results are actually tested and useful, which is the most important criterion for professors. The second is the student's research output, a student is still a student in the first month, but if you have a major breakthrough in the next month, then you will be a student as a professor. Because you have no one in the field who can compare to your results. It is precisely for this reason that Qin's university degree ranges from half a year to a year and a half.

The same is true for basic education, which was developed vigorously with strong government investment and private donations, but the school system is still chaotic. Each school has the right to choose its own textbooks. These textbooks are the more mature research results of various universities, and this is true of universities, so is the same for basic teaching, and many students have a wide range of interests, and universities have become their goal for further study. Although the teacher taught. But the initiative of the students exceeds the scope of the teacher's teaching, so many students graduate early and enter the university, in the Qin State, it is not surprising that you see a child who is only junior high school age doing research in the university, because his knowledge is far beyond ordinary people.

In order to encourage invention, the king of Qin also set up a doctorate position, which was mainly for those who had lifelong technical achievements. But later it was also developed for those who are engaged in economics and political studies. Because, King Qin gradually discovered that new things appeared in many aspects of the Qin State. For example, South Korea, under the vigorous promotion of Han Fei, established the first system of government with a separation of powers. The states of Qin were more open than those of South Korea, and they established a relatively complete trial system, with lawyers appearing first in each state. Juries also began to appear in court. The local states are more enlightened than the central ones. Therefore, the King of Qin established this position to complete the new situation after the emergence of new things in the Qin State.

In order to know the situation in the Western Regions at the first time, the Qin State set up a special telegraph line to the Western Regions. Be well prepared for the next war.

Shang Wen had to deal with the Xiongnu problem and the capital export problem, but Han Shu also added to the chaos regardless of all this. South Korea's new ambassador specially handed Sang-moon a personal letter.

"Honey." That's what it starts with. "Honey." One came when a reporter published a private letter between Shang Wen and Ying Yu in a newspaper, which Shang Wen believed violated private privacy. But Yingyu said that she did it, and she ordered it. The letters were also hers. Shang Wen was speechless.

So "dear" spread all at once because of the relationship on the letterhead, and it was mainly used for people who had a close personal relationship. Obviously, Han Shu thinks that the relationship between her and Shangwen is this relationship. Shang Wen shook his head helplessly.

"Have you been busy lately? Why didn't you reply to my letter. "Han Shu, as a queen, wrote to Shang Wen in the vernacular, and in the left-to-right manner commonly used by Shang Wen. It can be seen that Han Shu pays attention to the details of Shangwen.

"I think you're busy, otherwise you wouldn't have answered my letters. The situation in South Korea is good and improving. However, there are many people in our country, and you should know this situation, these people can't say that everyone goes to business, and it can't be said that everyone leaves their homeland to work in Qin. I want the Qin State to set up a factory in the concession area. In this way, a lot of problems can be solved. What do you think? "This is the requirement of capital export, technology output. Shang Wen didn't want to give any answer.

"There are specific questions that I think we can talk to. This is also a good way to discuss. Xianyang, I haven't been there for a long time. Don't know how the changes are? I heard that there was a camera in Xianyang, and I wanted to take a picture, and there was a telephone, which I had never seen before, and I heard that two people could talk from a long distance, and if that was the case, I thought there could be a telephone connection between the two countries. In this way, we can talk to each other on the phone. Do you say okay? I will send someone to inform you of the specific date. ”

Shang Wen quickly read the letter. The queen of a country is going to visit a country. I don't know if there is a precedent for this in the history of the Warring States. Shang Wen was a little overwhelmed.
