I Work as a Shopkeeper in the Treacherous World and Rely on My Body Temperature to Survive

My body temperature is the most expensive currency in this pawn shop. On the day I inherited my ancestral business, I knew my true legacy: a body frozen with all kinds of evil thoughts, and a ledger that said I had pawned my "heart." Every degree of body temperature needs to be exchanged for the strongest obsession in the world. Later—— That mute man who couldn't speak wiped away a hundred years of wind and frost for me in the middle of the night. His shadow once tried to touch my face, but he burned his origin for forty-three lifetimes for me, leaving only one sentence: "Choose yourself and leave the world alone." The detective captain who called me a bastard carved a burning oath into his blood. He said that he only sold his justice to conscience, but he didn't know that he was born to be the last anchor to lock my humanity. And the lunatic leader who wants to destroy the world looks very similar to me after taking off his mask. His fingertips were filled with the same coldness as mine, but he smiled at me with tears in his eyes: "Sister, every time you are warm, my brother's place will be an inch colder." "Your completion is my Ling Chi." When the body temperature finally reaches the level of a mortal, the book of debts opens with a roar. It says, the last and most fatal loophole in this causal loop—— It's me. [Pawn obsession, redeem humanity. This is an end-game deal with the world as the bargaining chip and body temperature as the scale.
