In 1904, the thirtieth year of Guangxu, Zhang Chunlai has been in this era for six years, from eight years old to fourteen years old, he is a half-old young man, but I don't know why, he still looks like he is only a teenager. Along with the growth and development of the beauty, it seems to have slowed down a section.

Chunya said that the legend has reached the introduction of qi into the body, which is the so-called qi training period to have this situation, but the monks in the qi training period are not more powerful than the martial artists like Chunya, except for a longer lifespan, there is almost no effect. It's just that Chunya can't tell the truth.

Zhang Chun has already realized that the problem is there, Zhang Chun's perception has been slowly growing, although it can't reach the point of the legendary inward vision, but any part of the body is uncomfortable, Zhang Chun and Lizhi are much more sensitive than others. Zhang Chun is able to perceive the benefits of purer, less polluted air for the body. He also began to be picky about food, and foods that are rich in nutrients and have fewer impurities are usually Zhang Chun's subconscious choices. Zhang Chun is also more and more sensitive to the breath of the animals and plants around him, the air is not as simple as carbon dioxide, nitrogen and oxygen, but a mixture of various gases, the more species of animals and plants, especially the more plants, the more comfortable the mixed breath is. This may be the legendary aura. This made Zhang Chun's environmental requirements for the construction of Zhangjialing almost harsh.

But why physical development slows down, Zhang Chun has not yet figured out the reason.

Thanks to Zhang Chun's insistence, all the villages now do not see the phenomenon of sewage flowing and chicken and duck droppings everywhere in other villages. Neatish, clean and orderly are the most basic requirements of Zhang Chun. Because the students liked the atmosphere of the Mengxue Hall, they would always find some problems with environmental sanitation when they went to the villages. Not to mention the fact that students with families are going home.

To a large extent, the rural environment depends on people's consciousness and persistence, and civilization is probably reflected in this regard.

After half a year of construction, the people of Qianli Village have moved into their new homes. Aunt Qin took the people into the textile factory, and the Zhang family's cotton was not sold, all of it was transported here, and the textile factory officially started. The entry of more than 50 female workers made the eyes of the young men of Qianli Village, who were almost singles village, shine. However, these women workers have their own dormitories in the textile compound. The two schoolgirls were so fierce that when they were building the house, they beat the long-term workers who were trying to run away. So it's just an empty idea.

These women also sent out words, saying that they would not marry illiterate, at least they should know how to write their own names.

As a result, a literacy boom was set off in Qianli Village. Before this, how Ren Chen Jizu and Zhang Yang forced them, these men who were already very satisfied with three meals a day didn't take it seriously.

During the winter sowing, the land of Qianli Village was planned and transformed. The cotton fields were divided into ridges, and five large buffaloes were ploughed. The cotton was pulled out in advance and piled aside. The yield of these cotton is not high, and Zhang Chun does not take them seriously. The land near the river has been converted into rice fields, and instead of wheat, peas are planted as fertilizer, and in the spring, the soil is turned into the soil and the fields are raised with water, and the seedlings have begun to be cultivated in preparation for planting the first season of early rice.

Yunlonghe does not have the habit of planting double-cropping rice, and Zhang Chun does not plan to plant it, because early rice is not delicious, and alternating planting with water and drought is more conducive to reducing pests and diseases. Therefore, the planting of early and late rice in Xiaolijiawan is just an expedient measure.

At the same time, the construction of the bamboo bark village was carried out. After the road leading from Zhupi Shangcun to Qianli Village was completed, the original road leading to Yunlong Town along the Nanhe River was abandoned. Because the Wu family should have taken the waterway to Nanzhang Village, that road was basically not taken. In addition, under the control of the Wu family, he couldn't even repair. The road leading from Qianli Village to Yunlong Town is left over from the previous construction of the water canal, which is wide and easy to walk. The new road was directly built in the village of Zhupi.

A ginning factory and an oil factory were built in the village of Zhupi.

This time, Zhang Chun couldn't send students out. There are also more than 40 students graduating this year, but the forestry station and the original seed farm accept most of them, and the outstanding students are being asked to leave by Zhang Di and Zhang Xiu. Six more boys joined the convoy. Zhang Chun is gone.

There are a total of 20 people in the ginning factory and the oil factory, half of whom were sent all the way from Tianjin, and they were all Northeast orphans secretly recruited by Zhang Fenglan by using the name of Tianjin Arts and Crafts School. It was first transported to Shanghai by ship, and then sent by Mr. Gu. Eight are orphans bought by Zhang Yang's family, all of them are poor and have no education, but they are all ten years old. There are also two pairs of international students who Gu Ming got over through his classmates.

Wang Zili, formerly known as Wang Cong, was named after he arrived in Japan, and he studied physics and chemistry at the Hongyuan Academy in Japan, and was an outlier among the vast majority of international students studying teacher training and military politics. Zhou Xin, formerly known as Shinohara, is the daughter of an overseas Chinese in Japan, but she grew up in Shanghai and came to Japan at the age of nine, where she also studied physics and chemistry at Hongyuan. Wang Zili is a very handsome boy who looks quite introverted and shy. However, this boy has a very stubborn personality and is very bold, so he directly abducted Zhou Xin back to China.

Wang Zili is nineteen years old, a native of Jiangsu, and his family has already set him up to marry, and he can be regarded as having a daughter-in-law. The family said that Zhou Xin could only be a concubine, and Wang Zili took Zhou Xin to Shanghai to work as a small editor in the "Science World" newspaper. Zhou Xin is indeed petite and cute, smart, loves to laugh, and has two dimples in one smile, which is very gratifying, and it is worthy of Wang Zili to be so desperate.

Wang Zili and Gu Ming began their correspondence when ordering a distiller. This was abducted by Gu Ming to a small mountain village again.

The reason is very simple, Wang Zili wants to detoxify cotton oil.

With the rise of the textile industry, the cotton planting area in the country has increased dramatically. Cottonseed oil extraction also appeared and was widely used. The Li family in Yunlong Town also built a press house to extract cotton oil. Although cotton oil has a taste, it is good for ordinary people to eat it, so many poor people eat cotton oil.

Zhang Chun refused to buy this cotton oil, saying that this cotton oil is toxic, and there is a compound called gossypol in it that has a good spermicidal effect, and it can be used as a contraceptive. Gu Ming wrote to tell Wang Zili that because he was in charge of the physical and chemical editing of Science World, he asked him to publicize it in the magazine, after all, most of the south is eating this cotton oil, which is a big deal. Wang Zili had never heard of it, but Zhang Chun said it so professionally, he came directly and asked how to detoxify cotton oil.

Zhang Chun also only understands one concept, where he knows the specific detoxification process. It is only said that gossypol is an acidic substance, and adding alkaline substances to cottonseed cake can achieve a certain degree of detoxification. For example, edible alkali, lime water or something. Experiments are required. Because it was about the fertility of too many Chinese, Gu Ming and Wang Zili regarded this as a major event of the death of the country and the species, so they returned to Shanghai and took Zhou Xin directly to Zhangjiabao.

Zhang Chun built a ginning factory in Zhupishang Village, and arranged the eight orphans bought by Zhang Yang's family in the ginning factory, because he also had to design and build a new oil factory, so Wang Zili was also the director of the ginning factory. In Zhupixia Village, the vacant house was used to purchase instruments and equipment to set up an oil laboratory.

It is relatively easy to detoxify in the laboratory, but it is necessary to extract gossypol and use mice to do a comparative test to determine the toxic effect of gossypol on sperm. This requires more accurate and rigorous experiments. The use of cotton oil extraction processes and residues, as well as the prevention of contamination, are also topics for the laboratory.

The cost of the laboratory is staggering, two thousand taels of silver is gone, and then it is expected that the detoxified cotton oil can come out as soon as possible to make up for the consumption of research expenses.

Xiao Li Jiawan was included in the Zhang family, because there were only two tenants, and Xiao Li Jiawan only had seven children between the ages of four and twelve who entered the Zhang family compound to study. These children are free. However, there are more than 30 seven-year-old children in Shinu Village who want to go to school in the Zhang family compound, and almost every family has one. Zhang Chun said that it is okay to go to school, and there is no need to pay tuition, and the pen, ink, paper, and inkstone are supplied by Zhang's family. But the children need to be fed three meals a day by their parents.

The villagers of Shinu Village saw that the children in other villages of the Zhang family were all from the age of four and above to go to school in the Zhang family for free, and it was always okay for their own families to provide one, so they gritted their teeth and agreed.

The students of the ten craft schools can be regarded as the students of higher occupations that can be cultivated in the Qing Dynasty, and they are students of machinery and chemistry respectively. However, to meet Wang Zili's requirements, it is still a little worse, so Wang Zili and Zhou Xin, in addition to teaching ten students, also got ten students who have reached the age of fifteen to learn machinery and electricity from Mengxue Hall to Zhupixia Village, especially the four students before Zhangjialing, who studied early, and their level is not lower than that of the students of Beiyang Craft School. Because the students of Zhangjialing Mengxue School generally have an advantage, that is, they have very strong hands-on ability and self-learning ability.

Wang Zili was also shocked by the work of the Agricultural School and the Medical Hall. Agronomy is a very partial discipline, even more than physics and chemistry. But what these fifteen or sixteen-year-olds are doing now is something I've never heard of. Moreover, it uses traditional Chinese theory, which is a comprehensive analysis and study of any species in a large and small environment. Taxonomy also seems to be more focused on systems and kinship ties, with more emphasis on evolutionary principles, which is not formed, but it is also quite surprising.

Wang Zili finally understood why Zhang Chun had to study and dispose of the waste from cotton oil processing, and he was a little paranoid about the balance of the environment and did not want any sewage to be discharged. The most difficult substances to deal with, Zhang Chun believes that almost all of them can be treated by biological treatment methods such as fermentation. He even asked the Institute of Agricultural Research to study how many bacteria and organisms are involved in the production of farm fertilizer. This kind of small environment research is very specialized.

In the lecture notes of the Agricultural Research Institute, there are already articles such as rice field environment, water environment, forest soil environment, etc., which are illustrated and detailed.

An unformed study is a septic tank water environment study, but the above was directly changed by Zhang Chun to a biogas tank environment study. It is believed that the main component of biogas produced by septic tanks should be methane. Heat and water are produced after combustion. Biogas can be harvested as fuel using a certain method. A sketch was also drawn.

However, this research was shelved due to a lack of personnel, and now the main direction of the Institute of Agricultural Research is breeding and planting technology, which is closely related to the study of these small environments. The little ones at the Institute of Agricultural Research are now mainly engaged in the breeding of rice, wheat and cotton. For the time being, it is preferred, but it already involves genetics. Of course, passive genetic analysis is the main one under the theory of evolution. However, Zhang Chun suggested that since environmental change can be mutagenic, there must be a way to carry out artificial mutagenesis.

Wang Zili is different, he is well aware of the value of methane. Therefore, it is a good reason to take over all the information of the fermentation environment and deal with the pollution.
