Private detective Lin Mo's office was burned down by the mysterious "Eternal Club" and he lost his beloved cat "Jazz". He was forced to accept the invitation to go to Jinghu Island, the club's headquarters. There, he was shocked to find that the guide "Mirror" looked exactly like his fiancée Su Qing, who died "accidentally" three years ago. "Mirror" reveals that the club pursues the mysteries of the universe and that "eternal life" is only a by-product, and tells Su Qing that the truth needs to pass the test of the core AI "Ouroboros". In order to seek the truth, Lin Mo passed the test and became "Candidate K-07". He learned that although Su Qing's body was dead, part of her powerful consciousness was captured by the club. The "mirror" is a simulation based on these fragments.
