The Qin State was in the midst of intense preparations for the museum, and the construction of the museum could only stay on the model. Because at this time, the weather has turned cooler, and some engineering projects are gradually being suspended, and the museum project is only finalized at this time.

The use of models has become more common in project construction. Concrete structures constructed with iron reinforcement are becoming popular due to cement. As a result, the original wooden structure houses are being eliminated in large numbers. Commercial buildings, especially some large stores, such as the large supermarket under construction by Yingyu, occupy a large area. This makes some engineering designs more difficult than ever.

The Department of Engineering and Architecture, which is specially established, studies these engineering projects on a daily basis. And the appearance of cardboard. This material is first used in the packaging of food products. It was later used in engineering. This move began with a student's bold experiment. Subsequently, it began to be used in large quantities and was quickly promoted.

There are many engineering projects that have been started in the Qin State now. This directly leads to the emergence of a large number of engineering personnel. Especially in combination with the original carpenters, they provide some mechanical references. Stone craftsmen, who then delve into the proportions of concrete, have been processed.

Other disciplines of the Qin State were also developed. For example, during this period, people began to realize the relationship between stress and density. The advent of glassware led to the start of some experiments with quantitative experiments.

These quantitative experiments began to explore some of the relationships about quality. Housing is mainly related to oxygen. This is very similar to the earlier phlogiston theory. But that's still in the lab.

In physics. Especially in terms of artillery, the achievements are very outstanding, at this time the relevant scientific researchers invented the ballistic pendulum, in order to measure the initial velocity of the artillery, and this achievement was soon used in the development of muskets.

And not only in terms of measurements, an artillery specialist appeared in this period. His name is Chen Yuan. He was the first to propose the theory of ballistic parabola. It was this theory that began to give rise to a large number of related mathematical problems. However, it is worth mentioning that during this period, the Pythagorean theorem was proposed. However, because an artillery aiming sergeant major also came up with such a mathematical theory. The two are engaged in a constant altercation.

But such a dispute is nothing. Because this need will soon settle the dispute. Astronomical calculations began, astronomers began to use sextants to measure the latitude of the earth, and colleagues began to measure the meridian of Xianyang. It is worth mentioning that the miniaturization of the clock has given them a new measuring tool.

In short, Qin's academic achievements are accumulating. It's all about the self-participation of the people. Discuss yourself. Although these theories are not useful for the time being, for example, some of these theories are still wrong, such as chemistry. But these theories were laying a foundation for the future development of the Qin state. This foundation is particularly important.

The Qin State is vigorously preparing to build a museum. Zhao was not willing to lag behind. After Li Mu went back. In addition to reporting on the specifics of the negotiations. Change began to select some teenagers as international students of Zhao State to study in Qin State. Li Mu also quickly repaired a book to Shang Wen.

"Grandpa, what do you call your grandson?" A teenager stood underneath Li Mu.

"Left car. Zhao sent a group of students to study in Qin. Would you like to? Li Mu went straight to the topic.

"Left car willing. Sun Er had already learned from the newspaper that the Qin State was undergoing earth-shattering changes. Xianyang is the same every day. The grandson has to go and see for himself without the order of his grandfather. "This boy named Zuoche is the famous Li Zuoche. At the end of the Qin Dynasty, the Six Kingdoms rose together, and Li Zuoche assisted Zhao Wang Xie, made great military exploits for the Zhao State, and was named Guangwu Jun. After Zhao's death, Han Xin asked him for advice, and Li Zuoche proposed: "A hundred battles and strange victories" The good strategy enabled Han Xin to recover the land of Yan and Qi. Li Zuoche left a legacy to future generations: "A wise man has a thousand thoughts, and there must be a mistake; A fool thinks a thousand times, and there must be a gain", and he also wrote a military book of "Guangwu Junluo".

At this time, Li Mu wanted to let his grandson be trained by studying abroad. I also want to get first-hand information about the Qin State through his grandson's study abroad.

Li Zuoche is in the environment of a family of military scholars, and naturally has a unique understanding of military affairs. He also very much wanted to be able to study in Qin. Because it was the first army to be fully equipped with firearms so far. Moreover, a mysterious air force is also maintained. All of this naturally attracted him like a mystery.

"This time I went to Qin State, grandpa didn't want you to expose my grandson's relationship. Do you understand? Li Mu asked.

"My grandson understood. My grandson has already figured out your name. It's called Muzi. Li Zuoche said.

"Yes. You go and get ready to go. Li Mu commanded.

Li Zuoche Shili withdrew.

Zhao Guo's international students this time are all teenagers. They all had to go to the military academy of the Qin State to study. Subject to the constraints of this era. Li Mu has not yet sent international students from private schools. This has to be said to be a shortcoming, which is also a shortcoming of the times.

Shang Wen received this volume of letters, because Li Mu still used wooden tablets. The content written on it is still incomprehensible, because the other party is using the Zhao script. Translated. Shang Wenwen confessed the contents of your letters. However, for international students who only send military students. Shang Wen felt a little incredulous. Because, the age of firearms, has heralded the importance of technology. And Li Mu didn't even send talents in this area. This is really a blind spot. But for something like that. He's no longer surprised. After all, it takes time, and time slowly changes the way we think about technology.

For the state of Zhao sent troops to participate in the military operations of the state of Qin. Shang Wen informed the other party in reply. These things. It will be completed through the talks between Wang Jian and Li Mu. After all, this is a military issue.

Regarding the matter of studying abroad, Shangwen arranged it in a timely manner. All international students are arranged to study at the Army Military Academy. As for the troops, it's up to them to choose.

After dealing with this matter, it is a matter of the northwest direction. At this time, the Qin state had already planned to establish the fourth and fifth states. The specific location of these two oblasts included one part of present-day Inner Mongolia, one part of Gansu, and the rest of the locations in present-day South Siberia. That is, the northern foot of today's Altai Mountains. The King of Qin had already chosen the names of the two states. Great Wangzhou, and Little Wangzhou. The location of these two states is very important, and they will geographically divide and disintegrate the connection between the Western Regions and the Xiongnu. Although for the time being, it cannot block the road of the Xiongnu westward. However, it was able to form a flank strike against the Huns.
