Mu Tingyun is the illegitimate son of the first master of Yitian Pavilion. This is a well-known secret. However, Mu Tingyun just wanted to be an ordinary little boy and live an ordinary life. He neither wanted to seek immortality nor dominate the martial arts world, and he was not even interested in his own life experience. When someone asked him, he only said: "I was picked up by my grandma." When the shocking secret of twenty years ago was completely forgotten by people, Mu Tingyun also maintained an ordinary life for twenty years until he met someone. He remembered the murderous aura and fragrance in the wind that day. Some things seemed to come to him eventually.
