Silver Sea, Upside Down City

At three forty-seven in the morning, their brains resonated at the same microsecond for forty seconds, and the same string of deep space coordinates appeared before their eyes. The mother of genius engineer Gu Linyuan died in the Midnight Project twenty years ago, and a crossed-out name was hidden in the relics; the comatose mother of neurosurgeon Shen Jianwei muttered "Don't open the letter." The pianist left his last words: It woke up. An old friend who faked his death sent a recording: Don't trust anyone who offers to help you. When a city hung upside down on the silver sea, they realized that they were just the first two pawns to wake up in the chess game.
