Ye Chuqi swam in the direction San San had indicated and soon spotted the crack. Calling it a crack was generous. It was so narrow that if she were any taller, she wouldn't fit through. If San San had a physical body, she might have beaten it senseless by now.
She slipped through the opening and made her way along the cramped passage. In many places, she had to press against the rock and climb carefully; at times, she had to hunt for another route through.
