Zhao Hai already knew what kind of existence a stone giant was. A stone giant was more like a tree demon than a tree demon. When a tree demon was at a low level, it could not leave the ground. When it reached a high level, it could leave the ground and fly in the sky like an ordinary demon cultivator. However, when they were on the ground, their combat power was more powerful.
However, the stone giants were different. They couldn't leave the ground at all. If they left the ground, they would die. This was really out of Zhao Hai's expectations. It seemed that they were the Kings of the ground, and they couldn't do it anywhere else.
To be honest, although the stone giant's power was very special, it was not very useful to Zhao Hai. At most, he would have an extra group of useful infantry.
