Terror Is Resurrected. Even the Evil Spirits Are Afraid of Me. What Should I Do?

Gao Han found himself reborn. There is no underworld in this world, and there is no reincarnation. After death, people either become ghosts or dissipate into heaven and earth. When Gao Han was being killed by the female ghost in red, he activated the underworld system, turned around and subdued the evil ghost. Villain 1: Why are these evil spirits helping him! Villain 2: Damn it! He didn't let the evil ghost help me, so I couldn't fight him! From then on, Gao Han embarked on a path to conquer the ghosts, establish the underworld, and dominate the world.
