Zhou Ran couldn't let go of his wife who died in an accident at the age of thirty. He used his invention to travel between seven parallel worlds, constantly collecting the souls of his wife's clones who died in the accident, hoping to change the fate of the wife's clone in the first parallel universe.
It's just that he couldn't resist the temptation in his heart after all, so he killed himself in the fourth time and space and stayed with his wife's clone in that universe.
All this eventually led to the pursuit of Xi Yueshan people. In desperation, he fled to his other self in the fifth parallel universe. After committing suicide, he gave those memories and the souls collected from other universes to his clone Tang Xiaoze in the fifth universe.
Tang Xiaoze initially sneered at this, but what happened later made him gradually believe it. How would he choose in the end?
Concept: You are just you. No matter how similar he is to you, he is not you.
