I Kill Souls in the Soul World

When people die, they turn into souls, and all that awaits them is for their spiritual power to dissipate and be completely wiped out. But there is a way - kill the spiritual power that absorbs other souls and make yourself stronger and more sustainable. There is no hell in the world, but the eternal souls fighting each other for eternity to become stronger are better than hell. But Ye Xia, as a human being, took the initiative to jump into this hell. People will always die, it is better to become the winner of Soul Battle before then.
