My name is Shen Yu, an undertaker at the No. 3 Funeral Home in Linyuan City. Others put make-up on dead people, but I tell fortunes for myself - my destiny is a negative number. Even if the number is negative, my mother will renew my life for me; the account of the renewal will be recorded on the copper abacus of Chamber's "Midnight Pawn Shop". But on my twenty-fifth birthday, the account was due. After the expiration, whether I am a human being or "material" of the Immortality Society all depends on whether they accept it or not. Until one day, a female corpse was pushed in, and the fate number showed: return to zero. But in the surveillance camera, she was still alive and kicking when she walked in. Someone is sucking the lives out of living people, stuffing the dried ones into the "furnace" under the Linyuan Building, and burning them into the nourishment for others' immortality. And I am the only one who can see the destiny, but because the "negative" is so ridiculous, even the evil spirit is too lazy to recognize me - the ink enters the ink tank, and I become the safest invisible person and the worst target. The night watchman raised me like a fish, waiting for me to swim into the furnace; the corpse collector Qin Sha stared at my eyes that could see through fate; the flash audio anchor Lin Qiqi held up his mobile phone and broadcast the story of my house to the whole city. There are still thirty days until my birthday. The black streaks are getting higher and higher day by day.
