After programmer Lin Chen worked overtime for seven consecutive days, his vision went dark and he transformed into the notorious and vicious villain Master from the fairy novel "Nine Heavens Killing Demons" - Master Hanhua. The system told him that as long as he completed the plot, he could go home. Thus, the hard-working social animal began his "acting" career: sarcastic remarks to the protagonist's apprentice Xie Yunshu, deliberately humiliating him, and snatching opportunities... He worked hard to act like a scumbag, just looking forward to being able to walk away when the plot ends. He thought everything was just a mission, but he didn't know that the apprentice who was pushed into desperate situations and protected behind him again and again had already seen through the gentleness under his cold appearance. When the plot came to an end and he needed to apologize with his life, Lin Chen jumped off the Fallen Immortal Platform without hesitation. He thought this was relief, but he didn't know that someone changed his destiny for him and turned him crazy. "Master, you can deceive everyone, why can't you deceive me?" "If you die, these nine heavens and ten earths will be just another prison to me."
