Yu Dan died. Fortunately, he was reborn, but unexpectedly he was reborn in a parallel world at the same time.
An unknown energy body claiming to be the administrator of time and space told him that a world can only have one identical soul. In order to survive, he began to fight for identity with himself in this world.
Same soul, same thing. Yu Chen also found that he had inappropriate thoughts about this impostor who wanted to steal his identity.
