Decent concept and intro to the MC but once he time travels it turns into the usual chinese slop.

I agree this concept and intro are decent, but it's not Chinese. That's definitely Japanese.

What's the one where he has to use... I think it's the heads? of 666 demons to do the same thing? And for his last demon head, he kills the demon king... or God?
Wish Mangos didn't just blur together so much in my head.
