Master Regretted Sending Me to Feed the Demon Queen

I was sent to the devil's purgatory by him. The bone nails penetrated my wrist bones and pinned me to death in the cave. With his connivance, my junior sister also picked off my love. After three hundred years of suffering and torture, I finally learned to stay away from him. But he knelt in front of me and pointed the tip of the knife at his heart. Blood splattered on his white clothes, but he held my hand and put it on his face, smiling paranoid and sickly: "Miaomiao, as long as you can come back, Master will give you whatever you want."
