How to Survive After Transmigrating as the Male Supporting Character

A modern college student gets annoyed after being cheated by a novel, so he makes an alternate account to insult the author. Unexpectedly, he transmigrates into that novel and becomes its number-one villainous male supporting character. Watch how he manages to win over the male lead and create a legendary cultivation romance together.

P.S. This is my first time writing a novel, so please feel free to point out anything I could improve.
