After Rebirth, I Became the Villain's Father

Mutsu was unexpectedly reborn, and as soon as he opened his eyes, he heard his enemy from his previous life calling him daddy. Things are changing, yesterday I had nothing, today I have the system! Bind the Shenkeng system to trick people and you will become stronger! "Ding! Gain 80 points of anger from your son, and reward the host with a Returning Beauty Pill!" "Ding! Gain 100 anger points from your ex-girlfriend and reward the host with a second-grade powerful pill!" "Ding! Harvest 250 rage points from the opponent and reward the host with 25 million in cash!" Mutsu said that a father is a father after all, and he must first teach his son how to behave. Not convinced? Hold it in!
