The night was silent, under the moonlight, only the sound of insects chirping outside the window, a mildly cool night breeze wafted in, refreshing and pleasant.
On the floor, a classmate blinked his sleepy eyes, obviously woken up by the urge to pee, just as he stood up, preparing to go to the bathroom outside.
A wisp of light pink smoke suddenly drifted into the room with the night breeze.
The classmate took a breath of the pink smoke, his eyelids drooped immediately, and his body tilted, falling down, with his face landing right beside another classmate's foot.
At the same time, the breathing of all the students in the room became noticeably deeper, with some people's snores louder, evidently, they were sleeping more soundly.
Whoosh!
Just as the pink smoke was wafting through the room, a figure flitted into the room like a ghost, moving with extreme speed.
The ghostly figure merely glanced around the room once and immediately locked onto its target.
Swish!
