Huan Lingtian Public Security Department

Humans rule the barbaric realm, and gods rule the wilderness. The beings in the netherworld rule the netherworld. Aggressive demons rule the demon realm. The powerful big demons are entrenched in the demon realm. They are not welcomed by other realms because of their weird tempers. "And I, Li Youran, am a little transparent in the Department of Public Security. Listen to me tell you about those years!"
