Zhang Chun made a one-to-five map with Lizhi in the lobby. It's much simpler in this picture.

The original drawings and raw data of the measurements were all sent to the Agricultural School. The simplified data and illustrated books remain in Zhang's office. Just like that, there is also a thick stack.

This also scared Xin Baojiu. Because on this picture, only a small part of the drawing is made, and the picture is very large, and four large sheets of paper full of fine lattices are glued together. Unfold this small office that wants to occupy Zhang Chun.

Behind Xin Baojiu, the three old men of the Wu Li Wang family appeared.

"Lord Zhang, I heard that you still have a big picture that can be hung on the wall of the lobby outside." Xin Baojiu put on an official tone, but he had a very happy smile on his face. It's not like the old man of the three families has an expression like eating.

"Yes, but it's too big to be suitable, so I'm making this small picture with Lizhi, and it's clear on it. For example, Qianli Village mainly grows cotton and rice, with an area of 1,000 acres and 6 acres of upper, middle and lower fields. It has been stated in the enlistment atlas that the tax was also paid according to the above figures. When Lord Xin was there, the garrison had time to measure the acres of land, mainly in the mountainous areas of Shinu Mountain and Zilin Mountain. The bandits were able to be exterminated because the bandits had no geographical advantage. ”

"The map is indeed a must-have for soldiers. Is this Baimin Lane really so complicated? Xin Baojiu pointed to the labyrinthine Baimin Alley.

"Baimin Lane is indeed complicated, it should be managed in a standardized manner, there are many eunuchs, several bandits, bandits did not attack here because the guards here are good, and the terrain is complex is also a reason."

"Yes, I heard that you used Western instruments for mapping?"

"Yes, the lowly Meng Xuetang has a discipline of mapping, and the map shed of the garrison team was taught by them, but there are only three people, and the soldiers of the garrison know too few words. This time, it was measured with the help of Zhang Xiu from Meng Xuetang. ”

"I see that the other houses in your picture are not as detailed as yours, so I should be able to calculate the number of acres."

"This, it hasn't been counted yet, and it can't be divided into upper, middle and lower fields. However, it is possible to calculate the total number of acres. This picture is for adults. The garrison has a detailed map, and the ravines in the fields have been noted, and the bandits are using these places to infiltrate the houses and Yunlong Town. ”

"Calculate it, report the results to the county, and I will ask the court for credit for you." Xin Baojiu glanced at the three old men behind him amusedly.

The three old men hurriedly bowed their hands: "Lord Xin, be merciful to your subordinates, Xiao Lao'er's acres of land have been measured by the imperial court mappers of previous dynasties, and please be merciful to Lord Xin and Master Zhang." ”

Xin Baojiu waved his hand: "The imperial court is backward in technology, and Zhang Zhidong has a new talent to set up a new school, prepare for the construction of a new army, and want to enrich the country and strengthen the army." Master Zhang did a great job. In this way, the garrison cannot stop surveying and mapping, and I have already reported the matter to Liu Guandao of the garrison battalion. The map of the jurisdiction of Yunlong Town is to be measured. However, Lord Zhang, the next step is to survey the acres of land and hand it over to Baojia, and figure out the upper, middle and lower fields. The total cannot be less than this figure. Lord Zhang, look"

Zhang Chun arched his hand and said with a smile: "Military maps, must indicate the customs and water conditions, these are very related to the level of the acres, Yunlong Town has experienced bandits, except for Zhangjiabao reclaimed some new fields, all of which are old fields. So there are still traces to follow. Elders, don't go overboard. However, there is really no meaning of surveying acres of land below. ”

Xin Baojiu's face sank: "What field is reported as field, how many acres are reported." Deceiving the acres of land is a serious crime in the imperial court, and the official will not forgive it. ”

The three old men finally breathed a sigh of relief: "That's natural, little old man will go back and arrange it." Thank you, both of you, for raising your hand. ”

Zhang Chun said with a smile: "This is not your responsibility, the ruler for measuring acres has always been inaccurate, and everyone knows the meter, so please work hard." ”

After the three of them went out. Xin Baojiu smiled: "Little brother, there are means." ”

Zhang Chun arched his hand: "Lord Xin, you have no intention of inserting willows." You see me drawing with my wife all day long, how can I care about this, my fingernails are full of ink. Zhang Chun raised his hand.

Xin Baojiu smiled: "I heard, you have a good master." What about Master Gu. ”

"I went to Zhangjiameng School. Master Xin, Xia Guan is going to change Zhangjiameng School into an agricultural college, and the students of Mengxue will go to school in Yunlong Town. The Mengxue in the town is too small. So I want to build a new Mongolian school in the place of the former military camp, the barracks have more than 300 acres, and the garrison camp was moved to Zilin and changed to the Li family, most of the Li family is now abandoned, and only shops are built on the street to rent to merchants. The area is about fifty acres. Xia Guan wants to buy this piece of land, and there will be a place for Xinxue. ”

Xin Baojiu nodded: "I'll tell the old guy of the Zhang family about this." But don't make too big a move, you're still young and have a great future, don't get caught up in some things. The people from Baimin Lane didn't come, but I could already hear some rumors. Brother, I'm just a seven-grade sesame official, you have to be considerate of my brother's difficulties. ”

Xin Baojiu didn't stop in the town and went back by boat.

The new head of the Zhang family came over and directly donated the land to Xinxue. He also promised to support the garrison in surveying and mapping, and to survey the acres of land as soon as possible, and to compile an atlas for reporting.

Mengxue's affairs were handed over to Gu Ming, how to deal with the people of Baimin Lane, Gu Ming was good at it. And there is no way to talk, and Zhang Chun is used as a buffer.

It was very difficult to build a sewer in Baimin Lane, and Zhang Chun put it on hold for the time being. The situation of East and West Street is relatively simple, and the streets are relatively standardized. The Yang family and the Wu family are quite positive. The Yang family is a relative of Zhang Chun, and the Wu family opened a garment shop, so it is good for the Wu family to be clean on the street.

However, what Zhang Chun didn't expect the most was that the commercial houses on East Street made a force.

Originally, these trading houses came to Yunlong Town to resell goods seasonally, and they were well-informed, and Yunlong Town was a small place, so they couldn't arouse their interest. If it is not the spread of the sphere of influence of the ruler of conscience. Their doors are still closed. The ruler of conscience and the turmoil attracted their attention. At first glance, Changchun wants to rebuild new schools, tidy up the streets, and build parks. They went to the yamen one after another to visit. Zhang Chun didn't see it, but saw Gu Ming. Gu Ming received a donation of one thousand taels of silver from them. Gu Ming announced that the renovation of toilets and the construction of drainage ditches by each family met the requirements of the yamen, and all the expenses were written off by the yamen in the park funds. Since the donation of the commercial bank is not in the name of an individual, it is not subject to the restriction of five taels of silver. A total of 12 commercial banks will be ranked at the top of the list in order of donation amount.

The construction of cesspools and garbage disposal tanks began to recruit craftsmen for construction.

The drawings were designed by the Agronomy School, which leveled out the gentle slope outside the town, created a garbage dumping and sorting yard, and built two large biogas digesters.

The water and residue from the digester can be completely discharged from the bottom, and the residue is dried to make a good fertilizer. The water from the town's sewers is filtered through a filter, and the residue is fermented in a digester along with the sorted garbage. The water from the digester and the filtered effluent are discharged into a primary sedimentation tank for sedimentation, in which reeds and water hyacinth are grown. Then to the secondary pool, the secondary pool is mainly planted with water lilies, calluses, shallots and other aquatic plants. The tertiary pond is large and occupies a large area of the river beach, and is mainly used for planting lotus roots and feeding fish. After passing through the tertiary pond, the environmental team said that as long as the treatment capacity is not exceeded, the water quality will be as clear as the water of the South River. The water from the digester is not discharged frequently and in large quantities, so it does not have an impact on the wastewater treatment plant. However, the construction quality of the tertiary sedimentation tank should be good and it should be able to be cleaned. The cleaned sludge is mixed with biogas residue for drying, without affecting fertility.

The Seiko team insisted on using biogas to generate electricity, but the technology was very difficult and immature. In addition to the problem of the generator, the other is that the pressurized liquefaction does not meet the requirements. In Zhangjialing, farmers temporarily light and cook so that they don't waste it. But not in Yunlong Town. It's not the technical difficulty, but the engineering difficulty and the application difficulty.

The chemical team laughed at Zhang Chun because they wasted biogas and reminded them that biogas is combustible and can be burned. The essence of explosives is also combustion, with nitrate # sour sweet # oil is so powerful, nitric acid biogas is even more powerful, as long as the nitric acid atomization and biogas are mixed with nitrification and cooling. However, it is highly toxic.

The maniacs in the chemical industry are now very obsessed with explosives, and the nitrate #soursweet# oil explosives that have been made are very good in the quarry, and they are trying to improve it into gunpowder that can reload bullets. After several failures, they synthesized liquid nitride in the laboratory, but it was so active that many people were injured. But the chemical team insisted that it was a good idea. Isn't it just to reduce the activity? It is not easy to strengthen, but it is simple to reduce.

Although the Seiko team was not satisfied, they still had a much larger digester on the farm to carry out their construction. So no more bickering. In the end, Wang took the initiative to set up a secret chemical laboratory in the treatment plant.

Wang Zili took over the construction of the treatment plant, but his temper was too hard and he was impatient to deal with the merchants. Externally, Gu Ming is still presiding.
