Mountain and Sea Agreement

I am Chen Yan, a hydrological inspector in the reservoir area. Ten years ago, my father disappeared on a July night, leaving only one sentence: There is a bridge under the water, and there are people under the bridge. Ten years later, on the same night, a body surfaced from the reservoir. The deceased was a surveyor who disappeared thirty years ago. His appearance remained unchanged and he carried with him a bronze fish charm engraved with the character Chuanheng. The old boatman said that this was not a water ghost asking for his life, but an old score settled. Pages are missing from the county annals, files have been deleted, and sonar has revealed three holes of the ancient underwater bridge, while there are only two holes on the drawing. Only then did I realize that those folk taboos, mountain and river rules, and water-preserving ancient relics passed down orally were never superstitions. "Book of Rites of Zhou" contains: There are dangers in mountains, balance in rivers, prohibitions in rivers, and protection in the world. The ancients wrote the imbalance of mountains and rivers, abnormal movements of floods, and abnormal movements of earth veins into a system that can be executed, broken, and kept. This system is called the Mountain-Sea Agreement. I'm just a plumber, I don't understand magic. I only understand water levels, rope knots, old bridges, archives and underwater propriety. But I know that some bridges cannot be broken down, some mouths cannot be sealed, and some agreements must be kept. The person who sees the ban, the person who lifts the ban, the person who keeps things safe, the person who orders mountains and rivers. This time, I'll keep my promise.
