At the summit of Chumaer Snow Mountain, 9,999 stone steps lead to the sky burial platform. Each step bears a name: the names of the coffin keepers through the ages, written in blood and soaked three feet into the stone.
Jiang Zhao receives a final letter from his grandfather and sets out alone for this forbidden place, sealed off by wind and snow. The letter contains only a few words: Don’t ask why. Go.
He becomes the eleventh coffin keeper, drawing lines in blood on the Heavenly Coffin every day. A luminous figure sleeps inside, tapping the coffin with six fingers and telling him where each bloodline must go. On the thirty-seventh day, the figure speaks: Sixty-three days remain.
