"Qianlong Bureau" is a high-intelligence crime suspense masterpiece set in a contemporary Eastern country. The story revolves around Lu Chen, a former economic investigation elite. Three years ago, he was framed for investigating a major transnational case involving power and money transactions. His mentor was wronged, his best friend died in the line of duty, and he himself was imprisoned. Three years later, he walked out of prison with a colder and sharper attitude, vowing to uncover the truth about old cases and bring the masterminds behind the scenes to justice. However, in this era of intertwined power, money and shady affairs, passion alone is far from enough. Therefore, he assembled three strange people with their own unique skills: Su Wan, a genius girl who is proficient in network attack and defense, Zhou Fang, a former drama actor who is good at disguise and psychological warfare, and Chen Ajiu, who is extremely skilled and is proficient in "retrieving objects from across the air". The four people formed the "Qianlong Bureau" and used extraordinary means to fight against extraordinary evil.
They walk on the edge of the law and challenge huge interest groups with wisdom and courage. From the financial shady business in Binhai, to the smuggling network on the southwest border, from the illegal fund-raising scam in the ancient town of Jiangnan, to the misappropriation of project funds in the Northern Industrial City, Qianlong Bureau has used exquisite layouts to reveal the truth time and time again, leaving the perpetrators with nowhere to hide. They are the shadows in the city, the light in the darkness, and the hope of the oppressed.
However, as the investigation deepened, they gradually discovered that the unjust case three years ago was just the tip of the iceberg. There was a huge and intricate force hidden behind it, and its tentacles even extended abroad. Qianlong Bureau not only has to face police investigation, but also has to engage in a desperate battle with cunning and ruthless opponents. Every action is like dancing on the tip of a knife, and every victory is accompanied by a new crisis.
