Pei Shu'er could only wait until Tang Zan was a suitable distance away to come out, otherwise, coming out too early would get her drowned in water.

Pei Shu'er was also a bit anxious, as she was almost at her limit. This water was truly no place for anyone to linger in.

And where she was, was the deepest part.
