From the bronze talismans of the Spring and Autumn and Warring States periods to the 31st-century colony on Mars, six timelines intertwine to form a civilizational code spanning a hundred thousand years. Xie Xuan, a scholar of the Wei and Jin dynasties, witnesses a bronze tree devouring the stars on the Fei River battlefield. Fu Li, a swordsmith of the Spring and Autumn period, discovers a Nine Tripods formation diagram capable of reversing time in Yunmeng Marsh. Lin Xia, a future archaeologist, deciphers a quantum fragment of the Bamboo Slips Record in the asteroid belt. When a bronze mask opens its mechanical eyes beneath the Martian soil, and the strange beasts of the Classic of Mountains and Seas become totems of interstellar war, humanity finally discovers that what we call history is merely the seed of an ancient civilization, sown in the folds of time. A hundred thousand years later, a bronze armillary sphere on the far side of the moon suddenly comes to life. The survivors of all six timelines will witness the ultimate truth at the Gate of Guixu: humanity is both the destroyer and the last guardian of the tomb.
