The Cipher on the Mysterious Bronze Coffin

In 2023, on the eve of a special exhibition titled “A Century of Archaeology in Northeast Asia,” a senior researcher at the city museum plunges to his death under mysterious circumstances. The only clue at the scene is a string of mysterious numbers engraved on a fragment of bronze. The police hastily close the case as an accidental fall, but the victim's daughter, young archaeologist Lin Wan, is convinced that her father was murdered for stumbling upon a world-shaking secret.

Together, they decide to investigate the truth on their own. Every clue points to a project her father devoted his later years to: a “Yuan Dynasty bronze coffin” mentioned only in scattered records from the Japanese puppet regime, but never publicly seen.

They discover that the bronze coffin is no ordinary relic, but the key to a vast underground empire codenamed “Other Shore Flower.” This empire is controlled by a “Mr.” who wields absolute power in both the legitimate and criminal worlds, and whose reach has long extended into every corner of society.

Each step closer to the truth brings a deadly attack from the shadows. And when they finally crack every code and find the bronze coffin's true location, what awaits them is not the truth of history, but the most brutal “accident” of all, one that will completely overturn their identities, memories, and beliefs...
