I Sell My Exercises, and the Buyer Practices for Me

Feng Yu was brought to Tianyan Continent by the stunning beauty Yun Muyao. After the two had a skin-to-skin kiss, Feng Yu activated a cultivation technique called the Book of All Worlds. Someone asked Feng Yu: "Boss, what's the secret to your being so strong?" Feng Yu smiled slightly: "There's no secret. It's all thanks to everyone. I'm just a salesman." "What do you mean?" Feng Yu: "I don't need to practice, the buyer is doing it for me."
