As soon as the words fell, Li Yifei appeared in front of him, crossing several steps in the blink of an eye. The thin policeman was startled and instinctively stepped back, finally losing his balance and falling backward. This time, the chubby policeman couldn't catch him, and the thin policeman rolled down the stairs until he stopped at the bottom.
"What are you doing?" the chubby policeman shouted sternly.
"I didn't touch him," Li Yifei replied casually. He indeed hadn't touched the thin policeman; the latter fell on his own, so it's not anyone else's fault. The chubby policeman realized that Li Yifei was difficult to deal with; he frowned and warned, "Don't mess around. Alright, who called for an ambulance?"
