August 8, 2028, is just an ordinary day in midsummer for most people, but for Lu Zheyuan, it is an eternal prison. The clock struck midnight, and the streets returned to the hustle and bustle of yesterday. The crowd repeated the same trajectory. Only his memory became clearer as time went by. From the initial fear and despair, to the wanton indulgence of using cycles, to the wisdom and responsibility accumulated over thousands of years, Lu Zheyuan's life was completely reshaped on the "same day".
He once used his unlimited time to master hundreds of languages, mastered top skills in fighting, medicine, finance and other fields, and became an "all-round genius" hidden in the market; he also had intersections with all kinds of people through countless repeated encounters—— There is the gentle and kind-hearted flower shop owner Ye Qinghe, the ambitious business woman Su Manqi, the mysterious female agent Chu Yao who carries a secret, and the physics professor Wei Mingxuan who is always curious about the mystery of his cycle.
However, the so-called "sense of comfort" is ultimately fleeting. When the indulgence fades, what is left is a deeper emptiness. He gradually discovers that August 8th is no accident. There are conspiracies hidden in the corners of the city that have been covered up by time, and the fate of the people around him seems to be inextricably linked to this endless cycle. In order to break the cage and protect those who really walked into his heart, Lu Zheyuan began to use the knowledge accumulated over thousands of years to explore the truth step by step.
