How Can I Be a Peerless Expert?

Xu Changsheng dreamed that he had killed the newly born Taoist Hongjun. When he opened his eyes, the world had become a world of immortality. He has no spiritual roots, and spent countless years in his dream just chopping wood, playing chess, calligraphy, and painting to cultivate his sentiments. How can he settle down and survive in this terrifying world of immortal cultivation? The war between humans and monsters begins, and a certain demon king enters the battlefield. "I learned chess from the human race Senior Xu and learned the Tao. I am a chess piece of the senior race. How dare you start a dispute with the human race?" A certain ancient cave opened, and a certain evildoer entered the cave. "I embarked on the path to immortality because of Senior Xu. No one is allowed to approach Senior Xu within ten thousand miles. I will protect Senior's path!" In the prehistoric fairyland, the Chaos List of All Souls awakened. "This is a sign that all the spirit treasures on the Chaos Spiritual List are gathered in one hand. Go find that senior!" As a result, tens of millions of people came to visit and called Xu Changsheng a peerless master. Xu Changsheng: "???" Stop bragging. How can I be a peerless expert?
