Reborn in the Land of Light

Ultraman, Original Ultraman, No Female Lead

I want to read something similar to Ultraman: I Am a Scholar in the Land of Light. Whether there is a System or not does not matter. The male lead must not be creepy or sleazy, and should not ruin his own appeal. Preferably he is intelligent. He can be righteous or villainous. If there are no recommendations on Qidian, please tell me about books elsewhere.
