The piece of copper with strange symbols in Fatty Wang's hand tied up four people who could not be beaten into a "wild team" - the street stall owner who wanted to get rich, the stubborn old man carrying the ancestral map, the serious fresh graduate of the history department, and the seemingly magician Feng Shui Mr.
What they are looking for is the "Xuanshui Kingdom" that cannot be found in official history. Legend has it that the ancient country hides a secret that can "borrow one's life for three hundred years." But chasing the clues, besides them, there are also the official team with file bags, the mysterious company with guns, and the mystery left behind by the father who disappeared decades ago.
The ancient city flooded by underground rivers, the fake villagers with repetitive movements, the parasitic "water god", the stone tablets with human sacrifices... Every step is on the line of life and death. The golden mask hidden by Fatty Wang, the unfinished diary of Old Chen, teammates who suddenly turned against each other, the "eyes" sticking out of the water...
Are these undocumented "wild people" digging for treasures, or filling in the holes left by their ancestors? And could the symbols engraved on copper sheets, murals, and stone tablets be just the beginning of another bigger mystery?
