Ye Chen began to realize that the moment they entered this prison, they also became suppliers of vital essence. In other words, this vast prison was nothing more than a collection point for vital energy.

"We only require a bit of your vital essence; we won't take your lives. You'd better obey and behave yourselves. If any of you dare to resist, don't even think about walking out of here alive."
