My Empire War Game

　　 In addition to roads, Su Lun started to build a water supply system for his territory. It has been more than ten years since he came to this world. Su Lun is still very unaccustomed to days without running water.

The vast majority of urban water supply in this era relies on well water. Well water needs to be purchased with money. Having a sweet well in the city is a stable source of income. Of course, some poor people choose to go to the river to carry water. The nobles chose the nearby mountain spring water more.

　　Because it is not easy to get water, people in this era seldom take a bath. It is considered hygienic for civilians to take a bath once a month, and Su Lun cannot accept that his barbarian soldiers do not take a bath for a month.

These energetic big guys have to patrol and sweep the wasteland every day. The dust and sweat on their bodies are inevitable, so Su Lun forced them to take a bath every day. Of course, this requirement was obtained by the barbarians and women. The unanimous support of Sulun, now even if Su Lun does not supervise the barbarians and women, they will supervise their husbands.

　　 Once he doesn’t take a shower, he can only spend the night outside tonight.

　　 When Su Lun came to the river to investigate, he saw a group of men and children with bare buttocks, jumping into the Hongsha River to take a bath.

　　 The weather is not cold at this time. It’s good to take a bath here, but it won’t work if it snows for a while. Suren is preparing to build water supply facilities as well as some public bathrooms.

　　 The magic of this world can do many things that technology could not do in the previous life, but the number of wizards determines that magic is difficult to promote. The water supply facility that Sulun is going to build is to be built in conjunction with the ancient Lanzhou waterwheel.

　　 has mechanical control skills, and Su Lun is very familiar with the principles and manufacturing of various machines. He is going to build three or four large waterwheels in Lanzhou on the Hongsha River. The water truck is used to raise the water source in the river, and then the water is sent to the reservoir in the city through the water supply channel.

　　 The reservoir must be built on a high place, otherwise the water will not flow through at all. The diversion canals outside the city used the elevated diversion canals of ancient Rome. In order to ensure the durability of these diversion diversion canals, Sulun specially used fossilized mud to reinforce these diversion diversion canals.

The diversion canal was erected from the riverside to the outside of the city. After thinking about it, Su Lun decided to build the water storage outside the town. The main reason was the expansion of the town. Now the area of ​​Zhenbei Fort is not large, and the length and breadth are 500 meters. It is not crowded for thousands of people to live in, but as the population of the territory increases, the current size is definitely not enough.

So Sulun has already planned to expand the town. This time, the expansion of the town Sulun intends to double the town's east, west, south and north sides, so that the area will be increased by four times, and the town will be upgraded to a large town that can accommodate 5,000 people. .

　　 From the Red River to the city, the length of the diversion canals is more than five kilometers, and because the location of the city is much higher than the river surface, these diversion canals need to be built into elevated diversion canals.

　　 The construction of the elevated diversion canal is very difficult. There is no architect in the territory who can build such a large project. Su Lun had to personally appear as a guest. After all, he came to this world for ten years and received a noble education on the right track, although he was just an observer. The education of the nobles in this world is still very strict, from etiquette, geography, riding, literature, architecture, history, martial arts, etc. to learn.

　　 At the beginning, Su Lun learned all this knowledge seriously. Although he didn't spend too much time on architecture, he still had some certainty to build an elevated diversion channel based on the theory of his previous life.

The diversion channel is about 60 cm wide and the water tank is 50 cm deep. The diversion channel is 30 meters from the highest point on the ground. The diameter of the waterwheel is 35 meters. In order to build such a waterwheel, Su Lun personally led people. Cut down the iron oak trees that have grown for hundreds of years near the Lotas Mountains.

The iron oak tree lives in a cold environment. The wood is hard and not easy to be deformed, and it is corrosion resistant and not easy to burn. It also grows very slowly. It takes at least two to three hundred years to grow to a height of forty or fifty meters. The wood-built waterwheel is both light and durable.

It took a few days to chop down eight iron oak trees in the Lotas Mountains. So Lun took the team back. There were also some various slaves captured here. They said that they were cutting down these iron oaks. Oak, Sulun also led people to wipe out two tribes of jackals.

In his previous life, Su Lun saw the waterwheel in the waterwheel park. When I saw this waterwheel up close for the first time, I felt very shocked. The large waterwheel 20 to 30 meters high was pushed by the current. Turning downwards, without relying on steam and electricity, it raises the water in the river to 20 to 30 meters.

　　 The structure of this waterwheel is not very complicated. According to the memory of his previous life, Su Lun combined his mechanical control skills to finally build the first large waterwheel in Lanzhou.

A huge waterwheel stands on the Hongsha River. The turbulent water drives the waterwheel to rotate. The water tank on the outer ring of the waterwheel is filled in the process, and then rises to three with the rotation of the waterwheel~www.wuxiahere.com~ Ten meters high in the air, and then dumped into the diversion canal, as long as the big waterwheel is not damaged and the Hongsha River is not cut off, there is a constant flow of energy to transport water.

　　【Large waterwheel: a superstar waterwheel made of iron oak wood, cleverly structured and durable, it is a very good water lifting tool, sturdiness +10, wear resistance +10, water lifting +10, power +15]

The elevated diversion canal is made of rock. Because the height is up to 30 meters, a deep foundation has been excavated below. The construction of the elevated canal also requires the supervision of Su Lun himself. In this era, it was used to glue the walls. There are few mixtures, and most of them use glutinous rice juice or pozzolanic cement.

Glutinous rice juice requires a lot of food, and Sulun can't bear to waste it. Sulun can't afford the price of volcanic ash cement delivered here, so he can only work hard. After each section of construction, he will turn mud into stone at these elevated diversion canals. Spells.

　　 After turning mud into stone magic, these rocks will be completely fused, and no gaps will be seen anymore. The effect is better than those of glutinous rice juice and cement. This kind of effect is good, but it is too expensive. In Carter City, hiring a wizard who is proficient in turning mud into stone will cost at least three hundred jinnars per day.

Even the nobles can’t afford this price. If Su Lun really has no money in the future, he can also consider acting as an architect. Every time he turns mud into stone, he can turn the ten-meter-long elevated canal into rock. Lun has to perform more than ten times a day, and he has spent a lot of energy on this water supply system.
