After the Quliang case, Zhao Yu had learned a valuable lesson. He learned that he had to take measures to protect himself, so he had applied for a gun permit from the Criminal Division, then obtained a pistol.
Although Miao Ying had since joined his team as the deputy team leader, she was not yet qualified to wear a gun on duty because of her relatively short time on the force. Therefore, Zhao Yu and Ran Tao, who was in charge of the field mission, were only two people with pistols in the Special Investigation Group.
However, at this moment, which was not long after Zhao Yu had pointed the gun at the stairway, he suddenly lowered it and placed it back in its holster at his waist. This was because he had heard Ran Tao's loud voice, coming from the stairway. Immediately thereafter, he heard Wu Xiumin's familiar and taunting lilt. A few seconds later, Ran Tao, Wu Xiumin, and Miao Ying appeared together in the hall on the first floor.
