The doctor lifted his head and looked at the two young people in front of the desk, his pupils shadowed with fatigue.
"Right, those face masks you sold, weren't they to the students of Tianhai University?"
Song Yutang quickly realized and explained.
Doctor Jia was taken aback.
"Yes, that's right... you're not wrong."
According to the doctor's description, the incessant nightmare that started haunting him a month ago was based on a bizarre experience from ten years prior.
He survived that incident ten years ago and thought it was all just an illusion; but in the nightmares, the fear continued to evolve towards the most terrifying direction, plunging him into an endless hell.
