DESPERATELY searching for a manhua

so the art style of this manhua is unique, and it's pretty old cuz i remember reading this during covid. so, what i remember (there's a LOT of manhuas like that but i really hope i find the correct one) :

- the artstyle : the noises are very pointy but the lines are crisp. they're not thin, they're thick.
- it starts off as the MC remembering his souvenirs from his past life as an emperor (duh) and then he remembers his mom owns a restaurant/takeout where they're being extorted for money by some punks that go to his school. then, he beat em up.
- at some point, a gang comes to beat him up in revenge and they have pretty colorful hair.
- a bit later in the manhua, the mc is on a cruise with this blue haired girl where he gives her a gem (not sure abt the gem) but she's in love with him.
- a seperate instance with the blue haired girl where she was competing with MC in a challenge in a something that looked like a stage and the MC ended up curing a little girl with like a white/blue flower.
- i remember vaguely at the begginging that a teacher is the incarnation of his past lover when he was a god and he snapped at her but then said nvm.
- MC HAS : brown hair, orange eyes, and dresses with a leather jacket.
- at some point, he went on a cruise and was fishing/hunting for sea monsters to put in an alchemy pot so he could strenghten his body.

PLEASE PLEASE PLEASE
