Restarting the Underworld Starts with Becoming a Yin Difference

[System] + [Invincible] + [No Heroine] + [Upgrade] + [Fast Pace] Su Yan's soul traveled through time and was able to restart the underworld system, becoming an underworld agent. I thought that by eating public food, I would have no worries about food and clothing, but I didn't expect that I was the only shady person left in the underworld! Moreover, the entire underworld has been closed, ghosts and monsters are wandering around the world, all living beings are devastated, and the earth is devastated! With no other choice, Su Yan had no choice but to embark on the path of capturing souls, slaying ghosts, and restarting the underworld. Evil ghosts, fierce ghosts, ghost heads, ghost bandits... Every ghost is captured obediently under the soul chain! Guimen Pass, Huangquan Road, Sansheng Stone, Naihe Bridge... Buildings are started one after another in Su Yan's hands! In the end, Su Yan discovered: "It turns out it's you who is causing trouble!"
