The supporting character's harem is very normal - Chapter 16: Evolution…

“I wasn’t born a lucky person, I’m just too strong.”

Lin Tian, who had reincarnated into the world of One Piece ten years ago met Garp, who was on duty to eradicate pirates, and become his student.

His will is tough and he is unwilling to be normal. However, his pathway was destined to be that way, being born in a small sect’s branch.

However, one day, his left eye merges with the eye of an Ancient God in an accident. From that moment on, he turns from a fish into a dragon.

He rises up like a star, walking the path of a legendary cultivator.

From being a tiny, small ant at the bottom of the world, he rises step by step, into a place full of powerful sects, strong ancient clans and countless geniuses.

This is an era of legends.
