Little villains father from Mahayanas Rebirth story in Western Fantasy

I actually got past the little villain father. It is a story whose hero is a Mahayana who failed during the ordeal of immortality and his soul was brought to western fantasy by a divine artifact. The stupid son harasses the hero and the cheap girl sacrifices the family for the hero. What should I do???

This novel was a harem genre work that had recently become famous on the Internet. I was criticizing the duality of the hero's personality when suddenly the phone's battery, which was connected to the power bank while charging, and the power bank itself was also connected to electricity, exploded and I I hung up the phone and joined the legions of time travelers. So far, everything is standard teleportation, but the problem is that the person I passed is the father of the little villain. Meanwhile, no matter how much I yell at the system, there is no response, of course. This is not the only problem, I think the biggest problem is my new half demon body. Devils in this world are enemies of humans and humans are enemies of demons, and naturally, as a half-devil, I am the enemy of both sides
