Zhao Hai walked around and found that this was a large city that could accommodate more than a million people. However, the city had been reduced to ruins. All the houses in the city had fallen, and so had the city walls. There were also some corpses that had been buried underground for many years. Some of them still looked the same as when they were alive.

In addition to these, there were many weapons in the city. In addition to the weapons commonly used in the soul world, Zhao Hai also saw other weapons. Those weapons were obviously not owned in the soul world. They looked more like the weapons of the destroyers. However, Zhao Hai did not find the traction crystal among the weapons.

Zhao Hai could not help but sigh when he saw the huge city ruins. This city must have been a very prosperous one in the past. However, it was destroyed in the war and was abandoned after the war. In the end, it was buried under the sand. To be honest, such an outcome was really a pity.

However, at the sight of this city, besides sighing with emotion, Zhao Hai was also a bit happy, because this city brought him hope. This was a big city that could hold 1 million people. How could such a city prevent from boiling water? that was to say, there must be a water source nearby. If that was true, it would be great.

Zhao Hai did not find any water sources when he went around the city. There were some Wells in the city, but they had been buried by the sand. Moreover, those Wells could not improve the situation in the destroyed desert.

Unwilling to give up, Zhao Hai walked around the city. Finally, he found a few rivers in the city. The first one was the moat outside the city. It seemed to be connected to a large river. Other than the moat, there were two other rivers that passed through the city. In other words, this city used to be a place with abundant water.

Zhao Hai followed the Three Rivers and found that they all merged into one. The river was very wide, and it was obvious that it was a big River. However, there was no water in the river. It had obviously stopped flowing.

However, Zhao Hai could feel the dense water vapor from the river. This made Zhao Hai even happier. He followed the river and finally found an underground river after a few days.

This was an underground river with plenty of water. The previous river channel had been destroyed, and this underground river was under the previous river channel.

Zhao Hai entered the underground river and took a look. At the same time, he went against the current to find the source of the underground river. What surprised Zhao Hai was that the source of the underground river was actually in the sword spirit Kingdom. It was a famous Lake in the sword spirit Kingdom. This Lake was known as the sword forging Lake. It was famous for its cold water, which was conducive to quenching swords. Of course, what was more famous about this Lake was that no matter how heavy the rain or how much water was poured upstream, the water of this Lake would always be cold. It had never risen, and there had never been a flood. This was the most promising part of this Lake.

Now, Zhao Hai finally understood why the water level of the lake had not risen. It was because the lake had an exit. Other than the river above the lake, there was also an underground river. The water from the entrance River also came from the underground river, which was why the water level of the lake was so cold and had not risen.

Zhao Hai was finally relieved after checking out the situation of the lake. If the underground river was upstream, it would be difficult for him to get water. If he took the water away, it would cause the water level of the lake to drop. If that happened, he would be discovered, which would not be a good thing.

However, the underground river he was taking water from was downstream of the lake. This meant that no matter how much water he took, it wouldn't affect the lake's volume. This was what Zhao Hai wanted to see the most.

There was only one thing he needed to be sure of now, and that was where the water of the river would eventually flow to. If the water of the river would still appear on the ground when it was downstream, then the water he took would definitely affect the people who used the river water. Therefore, he had to determine the direction of the water before he could really use the water.

Zhao Hai followed the underground river and swam downstream. A few days later, he suddenly felt as if he had entered the sea. He looked around and finally realized that he had entered a huge underground lake. The underground lake was huge, bigger than any Lake Zhao Hai had ever seen. Zhao Hai took another look at the lake and finally realized that the lake had an outlet. However, the water flow from the exit was less than one-tenth of the water flow from the entrance, which was why the underground lake was so big.

Then, Zhao Hai swam into the water from the outlet of the underground lake. In the end, he really swam into the sea. He had been underground all along the way, which meant that the entire underground river was underground. There was no water source above the ground. He could use the water from the underground river without any worries.

However, that did not stop Zhao Hai. What he needed to think about now was how to turn the water underground into the water above ground. Zhao Hai finally came up with an idea, which was to create a spring, a very large spring. At the same time, he would set up a magic array around the underground lake to direct the water underground. 90% of the water in the underground lake would be directed above ground, while the remaining 10% would still flow to the river through the outlet. This way, the water in the underground lake would not decrease. On the other hand, there would be a lot of water underground.

Of course, he did not just draw the water to the ground. If there was no outlet on the ground, the water would slowly form a river channel on its own. Water would flow from the river channel to the outside of the destructive desert. So, what Zhao Hai had to do now was not only to form a river channel on the ground, but also to return the water underground to the people in the underground river. However, the water had to form a Lake on the ground.

This was a huge project, and it was not easy to do it, especially in the destructive desert. Sand did not contain water. Fortunately, Zhao Hai found the ruins of a city, where there were many stones that could be used.

Zhao Hai immediately started to make arrays in the medium. Arrays with water properties, energy gathering arrays, and other arrays were all necessary. These arrays couldn't be too small. After all, these arrays needed to send water from underground to the surface. If the arrays were small, they wouldn't be powerful enough. In that case, the water wouldn't be able to be sent up.

Another important point was that in the process of the water flowing to the ground, a large part of it would flow through the sand. If it really flowed into the sand during this process, it would be very troublesome.

In the end, Zhao Hai came up with an idea. He built a waterway with stones and set up a magic array in the waterway to direct the water all the way to the ground. Then, he dug a big pit on the ground and let the water flow into the pit to form a Big Lake. From the lake, he would direct the water to the place where Zhao Hai wanted to build Lizhi city. He would open a few rivers so that the city would have a rich water network to use. Finally, he would let the water return to the lake and then back to the ground. It formed a cycle.

Without the stones from the abandoned underground city, Zhao Hai wouldn't have been able to do this. But with the stones, he could complete his plan. He wanted to build his own paradise, an oasis in the desert that looked terrifying from the outside!

Zhao Hai immediately went to the abandoned city to collect the stones. Fortunately, he had the natural energy and his interspace, which could store things, so it was very easy for him to collect the stones. He began to collect the stones piece by piece and put them into his interspace.

Zhao Hai had spent almost a month just collecting the stones. Then, he had to use the stones to build the water channel. He needed to build two water channels, one for water and one for water.

Fortunately, the two waterways did not need to be built too long. They were only a few hundred meters long. For Zhao Hai, this distance was very easy. It took him another ten days to complete the construction. (To be continued.) &Quot; if you like this work, you're welcome to come to Qidian.com to give your recommendation and monthly vote.
