Jiang Cheng slowly examined the strand of hair. He really hadn't noticed it before; it was too small and its color wasn't noticeable at all. So, Jiang Cheng hadn't seen it.
"Your eyesight is too good, Xiaokang. I still can't see it right now.
Wang smiled and said, "I'm old, with presbyopia. I can't see such small things at all.
Jiang Cheng held his breath and kept staring at the hair, afraid that breathing would blow it away.
The others, seeing Jiang Cheng's cautious look, didn't dare to speak either, and quietly watched Jiang Cheng.
The strand of hair wasn't long, not more than twenty centimeters, but it looked unusually thin. Jiang Cheng even questioned if a person's hair could be this thin.
Moreover, half of the strand was inside the door, with the other half outside. Jiang Cheng had never put much effort into deciphering such codes, feeling a bit challenged at the moment, but he had once read a book before.
