Xingyao City is prosperous on the surface, but in reality there is an undercurrent. Lin Yu was framed and imprisoned in a solitary room because he accidentally discovered clues about collusion between the organization's top executives and mysterious forces. Unwilling to be swallowed by darkness, he embarked on an adventure to reveal the truth with the help of Captain Chen, the "Night Ghost".
After escaping, Lin Yu fought side by side with the "Night Ghost". In the hail of bullets at the Tidal Pier and the life-and-death battle in the media center, he broke through the siege time and time again and exposed the conspiracy of the Imperial Family and the mysterious forces to the public. But this is just the tip of the iceberg. The mysterious force's horrific experiment - using ancient energy sources to create consciousness-control weapons is threatening the entire Xingyao City and even the world.
Lin Yu held the key energy crystal in his hand and looked for a way to crack it with his companions. The network of mysterious forces has tightened, and what awaits them are more deadly traps and challenges. In the game between light and darkness, can they uncover the final truth hidden behind the fog and protect the future of Xingyao City?
