Forgotten Title modern day cultivator

I remember that he was a weak and dumb person in high shool but after his girlfriend breaks up with him, he gets a system or something that allows him to cultivate. He ends up dating the school belle and her father actually knows his own father who he doesn't know but is some big shot in a big city. Apparently his mother ran away when she was pregnant because his fathers family was forcing him to marry someone else.

Eventually his father finds him and his mom and brings them back to the city. His whole family is some big shots in the country and his grandather is the head of the house hold but is sick and the mc heals him.

Basically the whole story is about healing people, beating up people, and showing off whose family is bigger. I know the story has quite a few chapters, probably 400+ translated already.

 

Sounds like Very Pure and Ambiguous something

 

Almost sounds like Returning from the Immortal World as well.

 

no reincarnation or some other mind in his body. He also has some cousins who he hangs out with quite a bit. He also starts a pharmaceutical company.

 

Just dropping here to learn the name of the novel.... sound interesting
