Three days before the flash flood, the spring water in the village became muddy little by little, the chickens refused to be put on the shelves, and the dogs were digging at the roots of the walls like crazy.
Only one person in the whole village understood it. He knocked on doors and drove more than a dozen families up the hillside, but he never came back.
Chen Ye was twelve years old that year. All his father left him was a black stone.
Seven years later, he was admitted to the University of Geosciences and pressed his hand on the rock formation for the first time - the earth suddenly opened its mouth.
The roar of the storm pressing down on the seafloor, the screams before the fault scabs over, the sound of mineral veins growing underground... The mountains and rivers of hundreds of millions of years are all speaking, but no one has ever understood them.
Until he discovered that the knock on the door that his father heard back then was ringing again underground in another city.
Some people are hunting him, some are questioning him.
And a burned file from fifty years ago proved that his father's disappearance was never an accident.
