After Zhang Chu returned to the valley, he arranged all his daily tasks and added a new task, he had to build two baths.

Under the order, the project started, the collective strength is strong, with the joint efforts of everyone, a burst of firecrackers sounded after more than ten days, ushered in a major event in the valley, the "public pool" opened, and the newly built bath door hung a gold-lettered plaque, on which there were four big characters in Zhang Chu's handwritten "public bath." Zhang Chu's skills in the calligraphy class that his parents forced him to take when he was a teenager finally came in handy. Zhu Xiucai, who wanted to show his skills at this time, was unceremoniously excluded by Zhang Chu. Zhang Chu wanted to come up with an elegant name, but because these four words were too impressive in Zhang Chu's mind in later generations, when he thought that there were only these four words in the public bath, he couldn't think of anything else. Zhang Chu had no choice but to write these four words. However, these four words have been unanimously praised, "Look at the captain who thinks more about our poor people, and build a bath to call it a public bath." ”

At the entrance of the men's bath, two disabled security guards managed the bathroom, and the two of them were very proud, not only did they receive a better salary, but they also had a sense of satisfaction in holding authority. There is a charge for bathing, and you can wash ten times for every penny. There is a large bathing pool in the bath, as well as a shower and a place to rest, and Zhang Chu ordered people to build a special fire wall in the bathroom, which burns coal, and the room is very warm. The low price and comfortable environment made everyone want to go in and try it, and soon the bath was overcrowded, and Zhang Chu had to implement the first limit order of the security team, and if you don't get the number today, please be early tomorrow.

Black smoke billows from the boiler room behind the bath, providing hot water for the bath. This boiler is the result of Zhang Chu's lack of business. In his previous life, he hid behind the boiler in the school water room and smoked, so Zhang Chu was deeply impressed by the boiler, and there was no difficulty in drawing the shape of the boiling water boiler, and the interior could only adopt a simple inner tank structure, with fire boiling water in the middle and surrounding it. Craftsmen use precious iron to build two boilers for boiling water. The construction of the boiler is also a test for the craftsmen, who have never done such a demanding job before, and all kinds of parts must be assembled together in the end, in Zhang Chu's words, do not leak. Zhang Chu invested a lot of money for this boiler designed by himself, and he had to see the progress of the boiler construction every day.

At a glance, Zhang Chu finally understood the difference between industrial production and handicraft workshops. The Chinese often say: "Long carpenter short blacksmith." "It turns out that the requirements for precision when working are not very strict, and many of them rely on the later stage to find a balance. This is not a big problem for ordinary agricultural tools, but it is a disaster for military production. There was no way for Zhang Chu to start from scratch and let the craftsman build a ruler out of stainless steel as a standard. Scales and weights were created, and finally there were standards for length and weight, and the parts built according to the standards were assembled much better. After adding water and coal to ignite, the boiler really boiled hot water. Problems encountered in the construction of boilers forced Zhang Chu to implement standardized construction in the workshop, unify the length and weight standards used by various craftsmen, and come up with the concept of design drawings. In ancient times, there were no design drawings, but the patterns only emphasized the style, and the dimensions were very brief, so Zhang Chu had to use his pitiful drawing knowledge to teach the craftsmen to draw drawings, emphasizing that in the future, the production of utensils must be made in strict accordance with the size on the drawings.

The women's bathroom, which was also built in the middle of nowhere, was even more lively, and the women were finally able to go out of the house to move outside. Now that the weather is getting colder, it is very inconvenient to bathe at home, and Zhang Chu built a bathroom to create a public place where only women exist, and Zhang Chu knew that the bath would soon become a social center for women in the village, and it is not known that the women's liberation movement would rise from it. The women's bath also had two women as managers, and as a result, they became the first working women in the village to have a regular income of their own, and their status in the family was greatly improved.

Zhang Chu took a turn in the men's bath, looked at everyone's happy appearance, and was very happy in his heart, and finally made a good start to improve everyone's life. However, things can never be done, Zhang Chu had to leave the bath and call Yang Blacksmith to prepare for the next job.

On the way out of the bath, Blacksmith Yang asked Zhang Chu very incomprehensibly: "Such a low charge is not enough for the cost of burning coal." ”

"The bathroom is not opened to make money, but just to get people to develop hygiene habits. Under the condition that all kinds of materials are still very poor, such a large amount of material resources and manpower are invested in the bath, which is to start from here and cultivate people's healthy and civilized living habits, which is the beginning of the new life movement, and many new measures will be implemented in the future to get rid of some bad habits. And now there is a shortage of medical treatment, and we can only make people less sick through good hygiene. Zhang Chu explained.

"Then why don't you just don't take the money?" Blacksmith Yang still has questions.

"People will not cherish what they come from, and if they don't take money, they will be considered to be what they deserve, and if they receive money, it is an equivalent exchange, and there should be no one in this society who gets it without paying." Zhang Chu wants to convey the concept of not working and not eating to everyone from all aspects.

Back at the team headquarters, Zhang Chu and Yang Blacksmith made another plan.

A few days later, something new appeared, the security team called on households to dig septic tanks, build new water flushing toilets, and the accompanying security team of excrement diggers were also employed. Of course, the security team must have a cleaning team, and the cleaning team of the security team has been established, and the streets of the bluestone slabs are cleaned and clean, and sometimes children can pick up and eat the grains that fall on them. Some litterers have also been heavily fined.

Later, "Zhangchu Hospital" was established, and the reason why the hospital was named after itself was to maintain the absolute authority of the hospital. And on a deeper level, Zhang Chu wants to perform major surgery on medicine. All the hospital recruits are counted as Zhang Chu's family members, and they can't leave if they join, and everything inside the hospital is kept secret from the outside world. Moreover, Zhang Chu also recruited some single women as nurses. Although other people have ideas, it is Zhang Chu's own business, and no one dares to say much. The level of this hospital is very low, only two of the Jianghu Lang who have been recruited from the homeless can see some simple diseases, and the rest of the people can only engage in hygiene and epidemic prevention. But the hospital is very bold, not only to treat the wounded of the security team, but also to receive foreign patients, but the most uncomfortable thing for patients is that every time a patient wants to be treated, the doctor inside will take out a contract for the patient to sign, and it is often written that if you die, what to do, who is responsible, the patient calls it "life and death", but at this stage, someone to treat is always much better than waiting for death, so the hospital is also crowded, doctors and nurses are very busy. Zhang Chu couldn't help sighing: "I have gone to ancient times, and the problem of difficulty in seeing a doctor has not been solved." ＂

It is impossible for otaku to be lazy, and soon a news comes: iron ore has been found in the upper reaches of the Qiaojiagou stream.

"It's great that my big plan can finally be implemented." Zhang Chu happily danced in the room.
