Zhao Hai and the others 'digging went very smoothly. Five days later, they had already dug to the bottom of Nanhua Gate City. However, Zhao Hai was even more careful at this time because he knew very well that this was the key to finding the water vein. He had to determine the direction of the water vein from the surrounding soil so that he could find two water veins in one go. He could destroy both of them as soon as possible. That way, Nanhua Gate City would be finished.
It was not easy to find the water, but Zhao Hai's spirit was much stronger than the others. He was also skilled in various formations, so it was not difficult for him.
Zhao Hai led the group into the cave. The cave was even bigger than it looked from the outside. However, there were some supporting pillars in some places, so they did not have to worry about the cave collapsing.
