1v1
In his previous life, Yun Yin was deceived by a disciple who was secretly the Demon Lord in disguise. After enduring every kind of humiliation, he took his own life in the Demon Palace's bedchamber.
After being reborn, he is bound to a Harem System. To win over the protagonist who caused his tragic death, he resolves to be a decent person this time and stop being an evil master who punishes his disciples.
But on the very night he is reborn, the protagonist suddenly rips open his clothes…
Yun Yin: “…”
He silently pulls out his ruler. Today, I'm beating you to death and ending this once and for all!
A few things to know before reading (feel free to skip~)
1. Since masters with a rare furnace physique are extremely uncommon, his master's master forced him to cultivate the Heartless Dao to protect him.
2. Neither of them realizes at first that they're in love with each other. It's mutual pining.
3. The master hits his disciple all the time, usually with a ruler, or by pinching and twisting him. The disciple is also very vengeful. They fight and love each other (not really).
4. The master is usually icy and looks like he can take anyone on, but he acts completely differently whenever he gets bullied.
5. The disciple has a filthy mouth! He's begging for a beating!
