Mo Weiliang was once a celestial harp fairy. In order to save Ying Huai Xu who was trapped in the cold pool, he cut his own string, which turned him mute.
Ying Huaixu, who returned from his injury, recognized the Pipa prostitute who rescued him as his benefactor: "Don't stain my eyes with dirty and mute things."
On the day of the decisive battle between immortals and demons, Mo Weiliang used scattered souls as sacrifices and refined the snow in the sky into a killing formation, but he pierced the Pipa prostitute's throat with an ice edge: "Ying only drank the blood of one person in his life, in the cold pool."
