In 2045, humans landed on Mars for the first time, only to discover a Qin-dynasty military formation of skeletons at the bottom of a crater, whereupon all crew members lost contact, leaving behind only the warning: "Humanity is dead." Three years later, young Xu Chong is secretly summoned to go to Mars with the mission to find his uncle Xu Xingzhi, whose life and death are unknown, and kill him. Reuniting in a Martian cave, his uncle smiles as before, yet awakens something in the dark. The family's sealed curse, the divine names on the bronze pieces, and the millennium wager of the gods using the mortal world as a chessboard are unveiled one by one. To kill a kinsman, or to kill a god?
