One day, out of the blue, he falls into hell. All he has with him is his desire to live and predator...
After 10000 years stuck in hell and becoming the demon king, the mc manage to return back to earth at the time 5 years after he disappeared and found the earth completely change from the one he remembered. Most of the mc power are repressed by the system and mc have to start back from the bottom. Mc is quite ruthless which is understandable since he had only been with demons for 10000 years and you can see how his sanity cracks at times lol. Fun story, totally recommended.
