1930, Shanghai Bund. Under a feast of fragrant clothes and shadows, blood spread quietly. Intelligence agent Lu Ying went from being a guest to being a prisoner. A rare gemstone - a sea crystal necklace - appeared out of thin air in his pocket, and a cold corpse with a knife in his heart dragged him into a carefully woven nightmare.
During his escape, he stepped into a world that should not have been discovered - a secret organization under the bustling surface of Shanghai, under the pseudonym "The Bund Exchange". Here, he was told that the faith he had been loyal to for the past three years was actually a cancer devouring the city. Trust collapsed, identity shattered. In order to seek self-proof and even more survival, Lu Ying must join forces with the Bund Exchange to chase a group of sneaking ghosts among neon lights and dark alleys, rivers and lies.
