Birthmark of the Immortal

"If even the memory is fake, who can you trust?" When forensic doctor Su Yu dissected a female corpse, she found that not only did the deceased's DNA match his own, but there was also a mysterious tattoo number - X-17 - engraved on her wrist.

From orphanage fires to undersea laboratories, from human cloning colonies to memory overwriting technology, every dead person is a part of the puzzle. And the most terrifying truth is that she herself is the core of the experiment.
