The murderer is the owner of the coffee shop, Sophia Kao. The proprietress of the coffee shop didn't give too many shots at the beginning of the play, which made the audience mistakenly think that she was the role of soy sauce, but in the later plot, her appearance laid the groundwork for the plot. Every time she comes out, there is a strange atmosphere. A detail: The proprietress made a cup of coffee that didn't suit Qin Ming's taste, and took the opportunity to collect Qin Ming's fingerprints and saliva.

It turned out that Chi always thought that Qin Ming had ruined everything for himself, because Qin Ming had lost his lover and father. Qin Ming looked at Dabao in the water tank, and the water was drowning her. Qin Ming grabbed the ring of the pool, drew a line on the water tank, and then smashed the water tank with a fire extinguisher to save Dabao.

Introduction to forensic medicine Qin Ming;

Lin Tao, captain of Longpan Criminal Police Team, and Qin Ming, chief of forensic medicine, are old friends for many years. Qin Ming's assistant resigned because she couldn't stand Qin Ming's eccentric temper. Li Dabao from the Trace Inspection Department was seconded to join the working group.

At first, Qin Ming didn't believe in Ren Dabao as a girl, but the stubborn Dabao showed quite good reasoning and observation ability in solving crimes, and her sense of smell was also extremely sensitive. The critical Qin Ming decided to keep Dabao. The iron triangle of Longpan police station has also begun to take shape. Starting from this "oil explosion mystery", Qin Ming, Dabao and Lin Tao have successively cracked all kinds of incredible cases.
