The water level in the lake was still rising, but Zhao Hai didn't have the time to care about that. He was planning to build a few river channels to form a cycle. In the end, the water in the river channels would still return to the lake.
The construction of a canal was not that easy. It seemed to be much easier than building a Big Lake, but it was not calculated that way. As long as you found the right side of the lake and made a big pit, it would be enough. However, the canal was not the same. You had to plan the canal well and leave enough space for future development.
After several days of calculation, Zhao Hai finally started to build a huge water net with the lake as the center. It was really a water net because this area was connected by various rivers and canals. The water net started from the lake and ended at the lake. The plant Castle that Zhao Hai wanted to build was right on the lake.
