However, given the circumstances at the time, Zhou Tian had already reached this point, there was no going back. At that time, he either had to successfully kill that group of Enemies or he would have to retreat from this world first.

Recovering their strength wouldn't be easy for the opposing side, but for Zhou Tian, if he wished, even if he left this world now, coming back later would likely not be too difficult.
