It's been winter for a long time, and the whole land seems to be peaceful again.

The Five Immortal Mountains in the Shu Dao Mountain have been officially named Wuzhi Mountain by Yang Yi, which is not a spoof, only because Yang Yi feels that in the future, the things that come out here may be the same as Sun Monkey, with the same power as Sun Monkey.

In the past half a year, Shamanaigu asked the army to comb through the Shudao Mountains several times, and now there is no trace of a bandit in the vast mountains.

However, although this Wuxian Mountain, which used to be a gathering place for bandits, is no longer a bandit, it is several times more populated than before. In addition to the workers and their families who are engaged in production here all the year round, there will also be an elite army of nearly 2,000 people stationed here for a long time.

This is a secret military factory carefully built by Yang Yi, and the defense level is almost no worse than that of Chengzhou Mansion, and those who can enter Wuzhi Mountain not only need to have a skill, but also need to go through ideological review, that is, political review.

Although it is a military factory, it is not only the production of military materials, but also some advanced civilian and industrial experimental products will continue to emerge.

In the deepest part of Wuzhi Mountain, there are several newly built mansions, which seem to be no different from ordinary houses from the outside, but the people of Wuzhi Mountain know that this place, known as the "Research Institute", is a forbidden place for everyone, and is strictly protected by a group of powerful black-armored soldiers.

Yang Yi, who was dressed in a coat and cloth clothes, walked out of the innermost room of the research institute, stretched out his hand and took off the linen hat on his head, standing in the courtyard and often inhaling fresh air, the strong smell of saltpeter in the room made him extremely uncomfortable.

Yang Yi took off the gloves he was wearing on his hands, glanced at Zhou Gongyi, who was frowning on the side, and said with a smile: "Old Zhou, although what I told you seems to be just a theory or research direction now, I tell you that it must exist, there is no doubt about it." ”

Zhou Gongyi nodded, frowned, and said, "Well, rest assured, Your Highness, I will definitely hurry up and study it again." ”

Yang Yi sighed, he can't blame Zhou Gongyi's slow research progress, if you want to blame Yang Yi, you can only blame Yang Yi for not reading well in his previous life, and he knows a little bit about knowledge, such as black powder, Yang Yi knows a "one, two, three" ratio, and almost nothing else, and he can't even memorize the basic chemical reaction equation.

Yang Yi saw that Zhou Gongyi's face was a little guilty, and comforted: "You don't have to be too discouraged, any of these things I told you will bring a change to this world, so you can't rush it." And these things are very dangerous, very dangerous, and if you make a mistake in the pool, it will cause a big disaster, so you must be careful. “

Yang Yi put the factory and the research institute in the mountains, in addition to the accident, the biggest reason is the safety problem, he doesn't want the killing weapon he made to kill the enemy uselessly, so he first uses the blood of his own people to open the light. Therefore, Yang Yi repeatedly told Zhou Gongyi and the workers of the workshop to pay attention to some safety matters, such as the fact that there should be no fire near the research institute, and the attention to the local sanitation environment related to food and other production.

Yang Yi and Zhou Gongyi got out of the gunpowder workshop and walked down the mountain for a while, when they suddenly smelled a strong smell of wine coming from a courtyard next to them.

Seeing Yang Yi look over, Zhou Gongyi immediately entered the courtyard, and walked out with a pot of wine after a while.

Yang Yi found a stone bench and sat down on the side of the road, took the wine jug handed by Zhou Gongyi, poured a glass, a strong aroma of wine came to his nose, and took a sip gently, the wine was very strong, far larger than the wine of this era, but there was still a gap between it and the high liquor that Yang Yi drank in his previous life.

Zhou Gongyi said with a smile: "Since His Royal Highness told us that we will improve the distillation tower to a rectification tower to distill the liquor, the wine produced by our workshop has been extremely rich, and I am afraid that no one in the world will dare to drink heavily in the future." ”

Yang Yi was not too happy, but shook his head and said: "No, it's still not enough, you try to lower the distillation temperature, and then purify the distillation repeatedly." ””

Zhou Gongyi exclaimed: "Do you want to distill again?" Who can drink that? “

Yang Yi smiled: "Of course you can't drink it, if you drink it, you will die, you just follow my method, I have other uses." ”

Zhou Gongyi nodded without hesitation, these days, Yang Yi's countless whimsical ideas have made Zhou Gongyi worship him as a god. The layman is lively and the insider's doorway, Zhou Gongyi is a craftsman, and his thinking is naturally more open than ordinary people, sometimes Yang Yi has some incredible ideas, but it is not impossible to think about it carefully.

Of course, Yang Yi couldn't explain to Zhou Gongyi what medical alcohol was, but this thing that didn't need too advanced technology and was extremely practical, Yang Yi had to pour it out.

It may not be possible to popularize medical alcohol for the time being, but when it is used in the military, it will greatly reduce the non-combat damage of soldiers.

Compared with these heavy industries, the most troublesome and worrying thing for Yang Yi is the Agricultural Science and Technology Institute in Wuzhi Mountain.

It is said that it is the "Agricultural Science and Technology Institute", but in fact, it is a few literate old farmers who are taking care of a few acres of land under the mountain, Yang Yi just explained the meaning of the four words "hybrid rice" to these people, and he said for a long time, Yang Yi's saliva was dry, and they were still confused.

However, Yang Yi has no intention of giving up, he knows what a high-output value grain will bring in this era, which is the foundation of any country. No matter how difficult it is, this "Agricultural Science and Technology Institute" must exist, and as for talents, this is not in a hurry, either slowly looking for them or cultivating them themselves.

Speaking of education, Yang Yi established an "experimental primary school" in Chengzhou Mansion, saying that the primary school is actually just a private school, but this small private school is different from any private school.

There are not many students in the private school, only about a dozen, including Liu Wenzheng's son Liu Xiaoduan, Doubao's sister Dousha, the late Meng Ji's orphan Meng Yu, and the heirs of several senior generals in the Chengzhou Mansion who strongly supported Yang Yi.

The model of the private school is planned by Yang Yi based on the experience of his previous life, and the knowledge is no longer a single teaching of the Four Books and Five Classics, but modern Chinese, geometric mathematics, history, politics and other subjects, among which geometric mathematics is taught by Yang Yi himself. When these children are a little older, Yang Yi also plans to teach them physics and chemistry.

Although for these children, knowledge is extremely difficult to accept, and there is even a taste of cultivating guinea pigs, but Yang Yi does not think that there is anything wrong with this, pioneers will always pay much more hardships than others, and if you want to progress, someone must always take the first difficult step.
