Meng Xi, the senior sister of the Qingyun Sect, returned from training, only to see that the junior sister Su Su whom she had protected since childhood was framed, had her golden elixir taken away, and died unjustly. In the past, fellow sects were confusing right and wrong, and the culprit Lin Yao was protected by Heaven and the sect by virtue of her status as the "Destined Mistress". In order to bring justice to his junior sister, Meng Xi pointed his sword at the sect and used thunderous means to punish those who betrayed their relatives and separated from their relatives. She broke through all the way to the realm of transcending tribulation, overthrowing the false way of heaven, and vowed to make all sinners taste the pain of life worse than death. How will this blood-for-blood revenge end?
