Wen Wen observed for a while and knew where the problem lay.
This guy had a dark cloud over his forehead, not because of some impending disaster, but because he was very sleepy, like staying up all night at an internet cafe.
He was so tired that he could fall asleep even while standing still.
But this guy would rather splash cold water on himself or pinch himself to stay awake, refusing to easily fall into sleep.
There could be many reasons for someone not wanting to sleep, but since Wen Wen was investigating sleep-related cases, the first possibility he considered was that this man's reluctance to sleep might be related to the sleep incidents.
After finishing his meal, Wen Wen staggered over to the owner, patted him lightly, and then calmly left the Aifei Region specialty restaurant, waiting in a secluded alley.
After waiting for more than ten minutes, the owner walked towards Wen Wen like a puppet, suddenly waking up only when he reached Wen Wen.
