After Having an Affair with the Immortal Lord, My Cultivation Level Skyrocketed

I picked up a beautiful sister covered in blood in a bridge hole. She pinched my chin and chuckled: "Little loser, do you want to practice dual cultivation?" Later, she pestered me to practice every night, and I went from Qi refining to Nascent Soul. Until one day, the heads of the ten major sects knelt outside the cave and shouted: "Welcome our ancestors to come out of seclusion!" She kicked me lazily: "Go and show off your unique skills to your disciples." I turned my head and swung out a sword energy, leveling three mountains. Suddenly, her smiling voice came from behind: "Good boy, I'll teach you something more exciting tonight."
