Zhao Hai sat in the boundless space and looked at everything that was happening in the outer space coldly. This situation was very normal. There were no rules in the outer space battlefield. Everything was based on strength. The reason why the nine sects killed the cultivators of the other sects was to prevent them from reporting the situation in this space. This way, the other sects wouldn't be able to get first-hand information, and their development in this outer space would fall behind the other sects. That was why the major sects had always maintained an advantage over the other sects.
The world of self-cultivators was the most ruthless. Here, if you were weak, you would definitely be beaten, because if you were defeated, they would be able to get more resources. With more resources, they would be stronger and live longer.
Zhao Hai didn't care about that. After the cultivators left, he stored all their bodies into his space and turned them into undead creatures.
