In his previous life, Li Muge was unwilling to be just the guardian of the demon world. He was overwhelmed by his nemesis Yun Qi everywhere. Abolishing her spiritual roots and destroying her cultivation base, she originally thought that she would be able to sit in the seat of the Demon Lord without any worries. Unexpectedly, instead, she was reversed by the Demon Lord who fell to the bottom of the valley and imprisoned her in the abyss where the sun never came. In the end, Li Muge thought he was going to die, but he didn't expect to be reborn. It happened to be the day when the army was approaching the city and was about to force the demon king.
