In addition to the roads, Sulun began to establish a water supply system for the territory. It has been more than ten years since he came to this world. Sulun is still not used to days without tap water.

Most of the water supply in cities in this era relies on well water, which requires money to buy. Having a sweet water well in the city is a stable source of income. Of course, some poor families choose to fetch water by the river, and the nobles choose more about nearby mountain spring water.

Because it is not easy to get water, people in this era rarely take a bath. Civilians can be said to be hygienic when taking a bath once a month. Sulun cannot accept that the barbarian soldiers under his command will not take a bath for a month.

These energetic burly men have to patrol, sweep the wastelands and other work every day. The dust and sweat odor on their bodies are inevitable, so Su Lun forced them to take a shower every day. Of course, this request was unanimously supported by the barbarian women. Now, even if Su Lun does not supervise the barbarian women, they will supervise their husbands.

Once he hasn't taken a shower, he will have to spend the night outside tonight.

When Su Lun came to the river to inspect, he saw a group of naked men and children jumping into the Hongsha River to take a shower.

The weather was not very cold at this time, and it was good to take a bath here, but it would not work after a while. Sulun was preparing to build water supply facilities and also built some public bathrooms.

The magic in this world can do many things that technology cannot do in previous lives, but the number of wizards determines that magic is difficult to promote. The water supply facilities that Sulun is preparing to build are prepared in combination with the Lanzhou water trucks of ancient past lives.

With mechanical control skills, Su Lun is very familiar with the principles and manufacturing of various machinery. He is planning to build three to four Lanzhou water trucks on the Hongsha River. He first uses the water truck to lift the water source in the river, and then send the water to the reservoir in the city through the water supply canal.

The reservoir must be built on a high place, otherwise the water cannot flow. The water diversion channels outside the city use elevated water diversion channels from ancient Rome in previous lives. In order to ensure that these water diversion channels are strong and durable, Sulun deliberately used mud to transform into stone to reinforce these water diversion channels.

The water diversion canal was built from the river to outside the city. Su Lun considered it and decided to build the water storage outside the town. The main reason was the expansion after the town. The area of ​​the town north fort is not large now, with a distance of 500 meters and a thousand people living there. However, with the increase in the population of the territory, the size of the current size is definitely not enough.

So Sulun has planned to expand the town. This time, Sulun plans to double the town from east, west, south, north, and across, so that the area will be four times larger, and the town will be upgraded into a large town that can accommodate 5,000 people.

The length of the water diversion canal from the Hongshui River to the city is more than five kilometers. Moreover, because the city is much higher than the river surface, these diversion canals need to be built into elevated diversion canals.

The construction of elevated water diversion canals is very difficult, and there is no architect in the territory who can build such a large project. Su Lun had to make a guest appearance in person. After all, he has been in this world for ten years and has received regular aristocratic education, although he is just listening. The world is still very strict about the education of aristocratic people, and he has to learn from etiquette, geography, riding, literature, architecture, history, martial arts, etc.

At that time, Su Lun carefully learned all this knowledge. Although he did not spend much effort on architecture, he was still confident in establishing an elevated water diversion channel based on his previous theory.

The diversion channel is about 60 cm wide and the sink is fifty cm deep. The diversion channel is thirty meters away from the highest ground, and the diameter of the water wheel is thirty-five meters. In order to build such a water wheel, Sulun personally took people to the Lotas Mountains to cut down the iron oak trees that have grown for hundreds of years.

Iron oak trees live in cold environments. The wood is hard and not easy to deform, and is corrosion-resistant, not easy to burn, and grows very slowly. It will take at least two or three hundred years to grow to 40 or 50 meters tall. The water truck built with this wood is both light and durable.

It took a few days to cut down eight iron oaks in the Lotas Mountains. Sulun then took the team back, and there were also some various slaves captured here. Speaking of which, in order to cut down these iron oaks, Sulun also led his men to wipe out two werewolves tribes.

In his previous life, Su Lun saw this in the Water Truck Park. When he first saw this kind of water truck up close, he felt very shocked. The water truck, which was twenty or thirty meters high, rotated under the water flow, and without relying on steam and electricity, he raised the water in the river to twenty or thirty meters.

The structure of this water truck is not very complicated. According to memories of previous lives, Su Lun combined his mechanical control skills and finally built the first Lanzhou water truck.

A huge water truck stands on the Hongsha River. The turbulent water flow drives the water truck to rotate. The water tank on the outer ring of the water truck is filled in this process. Then, as the water truck rotates, it rises to a height of 30 meters, and then pours into the water diversion channel. As long as the water truck is not damaged and the Hongsha River does not cut off, the water source will be continuously transported here.

[Big Water Wheel: A superstar water Wheel built with iron oak wood, with a clever and durable architecture, and is a very good water lifting tool. It is sturdy +10, wear-resistant +10, water lifting +10, power +15]

The elevated water diversion channel is made of rock. Because the height is thirty meters, a deep foundation has been dug below. The construction of the elevated water diversion channel also requires Su Lun's personal command. In this era, there is very little adhesive used to bond the walls, and most of them are glutinous rice juice or volcanic ash cement.

Glutinous rice juice requires a lot of food, so Su Lun is reluctant to waste it, and the price of volcanic ash cement is transported here, so he can only work hard himself. After every period of construction, he will use mud to turn mud into stone spells to these elevated water drains.

After the magic spell of turning mud into stone, the rocks will be completely integrated and there will be no gaps to see. It is better than the glutinous rice juice and cement. This effect is good or too expensive. In Carter City, hiring a wizard who is proficient in magic spells of turning mud into stone will cost at least 300 jinars per day.

Even the nobles cannot afford this price. If Su Lun really has no money in the future, he can consider acting as an architect. Each time he uses mud to turn mud into stone, he can turn a ten-meter-long elevated waterway into rock. Su Lun has to use it more than ten times a day, and he has spent a lot of energy on this water supply system.
