Archaeology PhD student Lin Xiao accidentally time-travels back to the ancient Shu Sanxingdui three thousand years ago. With theocracy shrouding the river valley, the high priest uses the name of the gods to control all living beings through sacrifices. Rescued by a young girl named A He, she encounters Yun, a junior wizard deeply entangled in faith struggles. Experiencing catastrophic floods firsthand, she witnesses false gods shattering to pieces before natural disasters. Amidst disasters and power struggles, the trio breaks through the shackles of theocracy, witnessing our ancestors break free from lies and survive with their own hands. When spatial-temporal anomalies arrive, Lin Xiao is forced to bid farewell to her dearest friends and return to the modern era, carrying a three-thousand-year entrustment to reveal the truth of Sanxingdui that belongs to mortals.
