Meng Xi, the senior sister of Qingyun Sect, returned from training and was shocked to learn that Su Su, the junior sister she brought up, was framed by Lin Yao, a girl newly brought back by her master, and died tragically. Everyone in the sect favored Lin Yao, and they all said that Su Su deserved his crime. Meng Xi took up her sword to take revenge out of grief and anger. Even after learning that Lin Yao was a destined heroine supported by pseudo-Tiandao and protected by fate, she never flinched. She bucked the trend and broke through the tribulation period, helping the true way of heaven escape, and finally deposed all the people in the sect who helped the tyrants to commit evil, and sought justice for the junior sister who died unjustly.
