Li Zicheng was a little surprised, how could this Sun Mengjie come back to this question? Seeing that Sun Mengjie's face was indifferent, Fang said: "The current microscope can only see transparent or near-transparent things, and the bacteria on the skin cannot be seen for the time being, unless it is ......."

"Unless what?"

"You can't see the bacteria on it until the microscope is improved, or the skin is cut off and scraped to a very thin, very thin place."

The students laughed again, who wants to cut off their skin and put it under the microscope? However, one of the students suddenly screamed: "Huh? It turns out that I have so many horrible germs on my hands and face......"

The students all came back to their senses, stroking and checking on their hands and faces, with indescribable fear on their faces.

Li Zicheng laughed and said: "You don't have to worry, although there are a large number of bacteria on the skin of the human body, the human body has its own way of protection, as long as the bacteria do not accumulate to the point of too much, it will generally not cause any harm to the human body, as long as you wash your hands and face frequently." ”

"Sir, can warm water wash away germs?"

"Warm water is not like liquor, naturally it can't completely kill bacteria, but as long as you keep your skin clean and wash your hands and face with warm water, you can remove most of the bacteria, and the remaining bacteria are no longer enough to cause harm to the human body.

In today's science class, the students felt that time passed very quickly, but when Li Zicheng left the school and returned home, it was already past the time for dinner at home, and Song Yulian had already heated the meal twice, and she was waiting anxiously.

Finally seeing Li Zicheng's figure, Gao Guiying couldn't help but say: "Zicheng, didn't you go to the academy?" Why did you come back so late today? ”

Before Li Zicheng could answer, Chen Qiudie hurriedly said: "The eldest lady doesn't know, today's class is very interesting, we are reluctant to get out of class, and before we know it, it's now." ”

Gao Guiying said lightly: "Ah, what have you learned, so interesting?" ”

"This ......" Chen Qiudie suddenly realized that he would never be as wonderful as Mr. said, but even if he said it, the eldest lady probably wouldn't understand.

Li Zicheng hurriedly took over the topic, "Gui Ying, what I teach today is some scientific things, it will be difficult to say that you are ugly for a while, and you have to study for a long time to gain something......

Gao Guiying had no interest in scientific matters, let alone the mind to study, so she said: "Self-contained, the meal has been heated twice, let's eat first!" ”

After dinner, Li Zicheng was originally going to stay in Song Yulian's bedroom, but Chen Qiudie pulled Li Zicheng and asked if there was any special sterilization method to kill the bacteria on her hands and face.

Li Zicheng held her little hand, stroked her somewhat tender face, laughed, and said, "Don't worry about Butterfly, although there are some bacteria on the skin, they will not harm your health, don't worry, as long as you wash it often." ”

Although Chen Qiudie nodded, there was still some disappointment in her eyes.

Li Zicheng simply pulled her closer to his arms, kissed her on the face a few times, and said: "There is no special effect, but in a man's saliva, there is an ingredient that can digest the bacteria on the skin, which is not a special effect, but there are always some effects......"

"Adult......" Chen Qiudie didn't know if it was true or not, but she would never refuse the adult's touch.

Li Zicheng picked her up directly, kissed her on the cheek, and came to Song Yulian's bedroom......

Song Yulian and Chen Qiudie were already lying in Li Zicheng's arms, snoring slightly, but Li Zicheng couldn't sleep for a while, and today's conversation with Liang Wencheng, or Liang Wencheng's expectations, made him feel a lot of emotion.

Last time, when he attacked Ganzhou and even Mai Li cadres, Liang Wencheng was the only one who had a cautious attitude, but now, in Liang Wencheng's heart, he was already thinking about Longyou.

This is Liang Wencheng, but also the civilian officials of the Xining Army confidence in the Xining Army is increasing, with the victory of several wars, the territory of the Xining Army is expanding, and the people's hearts are also expanding.

The Xining army wants to cross the Yellow River and enter Longyou in the east, although the food problem is basically solved, but it still needs silver, grain and food, grain and salary are indispensable, and now the Xining army's salary and silver mainly come from the sales of distilled spirits, glass, and perfumes, and the production of distilled spirits and glass has entered a stable stage, but perfume is a seasonal commodity, whether it is flowers or leaves, must be in the spring and summer, before there are raw materials, and now is the season when raw materials are the richest.

Perfume is a high-end consumable, and it is likely to become one of the most important sources of silver for the Xining army, and it can not continue to be produced in the small hall of the central government.

There is also a problem, once the Xining army enters Longyou, the imperial court will definitely block the various passages of Longshan, and the trade routes east of Xining will be blocked.

Longyou, Longyou, Li Zicheng silently muttered in his heart, and suddenly thought of the word "Delong Wangshu", Longyou already belongs to the mainland of the Ming Dynasty, in addition to going east to the passage of Longshan to enter Guanzhong, and then enter the Beijing Division, you can also take the southern route, like Ren Erxi, go to Chengdu first, and then go east along the Yangtze River.

As long as the imperial court did not block the Shu Road, Xining merchants could take the southern route.

According to the message sent back by the rangers, south of the Qinling Mountains and north of Daba Mountain, along the Han River, there is also a passage that can pass through Huguang, as long as you start from Hanzhong, you can go directly to the hinterland of Huguang.

However, will the imperial court let the merchants of Xining go south?

"Vested Long, look back at Shu", Li Zicheng doesn't care whether this sentence is positive or derogatory, once he gets Longyou, there is no reason not to focus on Sichuan, which is also the frontier of the Ming Dynasty.

If you can occupy Sichuan, you don't have to worry about the imperial court cutting off the Shu road, there are many ferries along the Yangtze River, it is difficult for the imperial court to fully deploy, with the degree of corruption of the Ming court, it is impossible to completely block the trade route, even if the imperial court is deployed along the Yangtze River, the merchants will have a way to establish an underground trade road.

Occupying Sichuan, in addition to controlling the trade road, there is also an advantage, that is, grain, now entering the Xiaoice River era, the temperature in the northern region has become lower, precipitation has decreased, but Sichuan belongs to the south, still the wind and rain are smooth, and the grain and products of the Chengdu Plain are even richer than before.

Of course, this is only a long-term plan, and for now, it is better to take care of the Xining Army's own affairs first, and make various preparations for crossing the Yellow River to the east.

When I woke up, the sky was already bright, Song Yulian had already gotten up to make breakfast, this time, Li Zicheng did not lie in bed to exercise on Chen Qiudie's body, but went to the training ground to run more than ten laps.

In the morning, Li Zicheng went to the school as usual to teach the students, these female students are Li Zicheng's experiments, and now they are entering a critical moment, as long as Li Zicheng is in Xining, he will find time to teach them.

After lunch, Li Zicheng first handled some military and political affairs in the study, and then He Xiaomi came in, "My lord, my subordinates have found a house in Eryuan Lane, Dongmen Street!" ”

"You take a look first, and if the price is right, buy it first!"

It is not difficult to buy a house in Xining as a workshop, but Li Zicheng has a headache about who to send to manage the factory.

There are not many talents available around him, and to manage this factory, it takes a certain amount of experience, and it is best to have business experience, so the first thing he thought of was the businessmen in Xining.

But Li Zicheng quickly rejected this idea, these businessmen have been in the mall for a long time, too sleek, and the demand for remuneration will be great, and more importantly, they are just a community of interests with the Xining Army, and they cannot be regarded as his close friends, and it is really a little uneasy to entrust them with such an important and secret task of producing perfumes.

Li Zicheng then thought of Sun Lin, his brother-in-law, who is a little wooden by nature and meticulous in his work, if he commands the troops on the battlefield, I am afraid it is not that material, but let him manage a factory, especially the goods produced in the factory do not have to worry about sales, he is a suitable candidate.

However, Li Zicheng still rejected this idea, Sun Lin, as the only male and supernumerary staff in the school, was trained as an educational administrator, and the female students of Xining Girls' School may be the gentlemen of the new school in the future, that is, teachers, but to manage a school, women are naturally disadvantaged, and in this era, it is difficult to be competent in this regard.

Li Zicheng only recruited female students at the beginning, and it was also a matter of last resort, before the achievements of education were fully displayed, who was willing to put men in a completely unpredictable school?

Men are laborers and the pillars of the family, while women can only engage in some simple housework and cannot bring economic income to the family, so Li Zicheng used the form of food and salary to hook their parents, and when these female students graduate, they will open a new school in the future to teach boys, which can be regarded as a curve education.

Sun Lin's entry into the Xining Girls' School was a complete accident, he was a quartermaster, and when distributing food and equipment, he needed written records, so Li Zicheng included him in the girls' school, as a supernumerary student, and learned some new knowledge and Chinese characters by the way.

But his male superiority has been reflected, in Li Zicheng's mind, in the future, he will be the principal and other administrators of the new school, and at present, he and Li Dan and others are still undertaking the task of compiling dictionaries, and they cannot be delayed.

After thinking about it, Li Zicheng decided to find a person from the pro-soldiers, as the director of the Yishen Perfume Factory, although the pro-soldiers lacked management experience, but they were more intimate to the Xining Army, to themselves, and the requirements for remuneration would not be too high, as long as they gave proper guidance, they should be able to do this job.

Moreover, as the pro-soldiers gradually serve in the army, industry and commerce, it is convenient for them to control the army and economy of the Xining Army, and as long as there are no problems in the general direction, these soldiers who come out of the pro-soldiers will be like graduates of the Whampoa Military Academy, and they will always be able to become their cronies.

Of course, there are no absolute things in the world, and if there is a big change in the Xining army, or even an avalanche-like defeat, everything will be difficult to say, but Li Zicheng believes that even so, there will always be people born in the army to follow him.

In the end, Li Zicheng selected a relatively clever soldier named Fan Wenhui from among his own soldiers to manage the Yishen Perfume Factory.
