Linchuan was once the most talented outer disciple of the Qingyun Sect. Three years ago, his most respected senior sister Qingyao (the sect's genius) was brutally murdered. The martial arts aura left at the scene pointed to the high-level sect, but the sect dismissed the case as "harmed by the demon sect". Linchuan was framed and expelled from the sect because he questioned the truth, and lost part of his cultivation. Three years later, Linchuan concealed his name and resumed martial arts practice. With the "Breaking Eye" power he accidentally obtained (which can see through the disguise of martial arts aura), he sneaked back to Qingyun Sect as a handyman disciple. While hiding his strength and practicing secretly, he carefully investigated the truth behind the murder of his senior sister, only to discover that the murder case that year was not an isolated case - in the past ten years, the disciples who had disappeared and died tragically in the sect were all secretly related to the case of his senior sister. As the investigation deepens, Linchuan encounters many fatal pursuits and meets Su Yu, a low-level disciple who is also suspicious of the sect. The two work together to reveal the sect elder's conspiracy to use his disciples to practice forbidden arts and cover up ancient secrets. The real culprit who killed his senior sister was actually a core figure in the sect that he had never suspected. Linchuan used martial arts to prove the Tao, used wisdom to find the murderer, broke the shackles of the sect, revealed all the truth, and finally killed the real murderer, reshaped the order of Qingyun Sect, and embarked on a higher martial arts road.
