When others died, only a death certificate was left, but what Shen Yan picked up was a life that could still be used.
Eighteen years old, a lifeless person, can temporarily bear the legacy left by the deceased: borrowing the life of a firefighter to find an exit, borrowing the life of a doctor to save people, borrowing the life of an old detective to chase the murderer, borrowing the life of an ordinary person to finish what he has not finished.
With each life he borrows, he gains an additional set of skills, as well as the habits, memories and obsessions of the deceased. The deeper the borrowing, the less like himself he becomes.
When someone started collecting lives specifically, Shen Yan realized that his blank life track might not be a flaw, but the only container that could hold all lives.
