Seeing that Xiao He had been trapped within Zhang Yan's formation, Sun Xian immediately realized that the situation was not promising. Later, when she noticed the arrival of a Nascent Soul cultivator, she felt the matter was far beyond her ability to meddle in. After calming her breath several times to restore her strength, she seized the moment when the red-haired Daoist and Zhang Yan were conversing to quietly raise a tunneling light that skimmed the ground and flew away. Before long, she had vanished without a trace.
The disciples who came from the Six Rivers and Four Islands were mostly direct relatives of the island masters. Witnessing that the Nascent Soul True Master who arrived later was equally at a loss against the array formation restriction, they, too, feared Zhang Yan might remember them and seek them out in the future. Like Sun Xian, they secretly rode their tunneling light and fled.
