An ordinary person who was once the strongest soldier codenamed "Yam Luo" returns to the city to investigate the truth behind the death of his best friend. As an inconspicuous security consultant, he sneaked into the AXA Group where his best friend worked before his death, and started a road of revenge and protection by "pretending to be a pig and eating the tiger".
During the investigation, he unexpectedly met Su Wanli, the stunningly beautiful and talented forensic doctor in charge of the case. With her keen professional sense, Su Wanli had already discovered that the case was full of doubts, but she suffered from pressure from the top and interruption of clues. When Long Qian appeared, she was initially regarded as a handsome but troublesome "connector". During the confrontation and testing, the two went from being wary of each other to gradually discovering that each other was the key to solving the mystery.
On the surface, Long Qian is a lazy and casual ordinary employee who occasionally shows extraordinary skills. Secretly, he uses his vast background and connections (the strongest connections), as well as his thunderous methods and deep scheming honed on the battlefield, to gradually tear apart the huge black network entrenched in the shadow of the city. He not only wants to avenge his brothers, but also protect the people he wants to protect in this game of wisdom and strength, and eventually become the well-deserved underground king of this city.
