After Pushing Me Off the Demon-Slaying Platform, Master, She Regretted It

When my junior brother became a demon and accidentally killed a mortal, my master did not hesitate to push me out to take the punishment for him. Then, for him, he chopped off my spiritual root and cut off my life sword. Force the demonic energy into my body. When I was thrown off the cliff, Master looked at me condescendingly: "Who do you think you are? If I hadn't been kind-hearted, how could I accept you as my disciple?" In despair, I thought I would die at the bottom of the cliff. I never expected that the world's number one immortal, who had been in seclusion for many years, would come all the way to save me.
