However, there was no response from Yu Bin in the restroom, and the police officer called out Yu Bin's name several more times without any answer, which immediately made the officer mutter that something was wrong. With a strong push, he opened the restroom door, only to find no trace of Yu Bin inside.
The policeman became anxious at once. The restroom was only a few square meters in size, small enough to take in at a glance, yet Yu Bin had vanished without a trace, leaving no clue as to where he could have gone.
As the policeman turned around to go back and notify his colleagues to come and search, he suddenly saw Yu Bin, who had disappeared, dropping down from above the ceiling, seizing the policeman's neck from behind with an arm and closing the restroom door with the tip of his foot. Yu Bin had his arm around the policeman's neck and covered his mouth with his hand.
