Zheng Bo tried hard to close his eyes.
He had high blood pressure at the moment, but he had taken his medicine before going to sleep.
About half an hour later, as he was about to drift off again in a daze, Zheng Bo's eyes half-closed, he was on the verge of falling asleep.
But the next second, he thought he felt someone standing near the foot of the bed, which startled him and made him open his eyes immediately.
There was nothing there.
Zheng Bo's heartbeat started to accelerate. He lifted his head to look carefully and indeed there was no one there. He turned his head to look behind himself, towards the other side of the bed, and saw no one.
After thinking it over, it was possible that he had been confused as he was falling asleep, or maybe he had mistaken the shadows of trees cast into the room.
He lay down again and closed his eyes.
Sleepiness came over him quickly.
However, suddenly a faint rubbing sound arose, as if it were the friction between fabrics.
