On the evidence shelf of the criminal investigation team, the tube of samples mixed with poisons and engine oil has become an extremely troublesome "gray evidence" in Su Yan's eyes. This forced Su Yan to face Fu Yelin, a man who was doing everything in the underground racing circle. The two were in tit-for-tat situations because of the case. However, after being carefully calculated by the underworld again and again, they had to rely on each other's strength to break the deadlock. Su Yan relied on his excellent forensic skills to unearth the truth hidden behind the corpse, while Fu Yelin relied on his "wild domain" connections to fill in the information blind spots that were difficult for the police to reach. When the "grey evidence" connects the truth and sincerity, the intersection that originally started as a confrontation eventually became the best reliance on each other in the darkness.
Intention: Work hard.
