Tong Yunshu indeed doubled back.
She stayed with Yang Fei in the Hidden Sect World, helping him continuously repair the formations.
Every day, the formation that maintained the stability of the Hidden Sect Plane would be overwhelmed by the collapse pressure of the Hidden Sect Plane, showing various damages.
Yang Fei and Tong Yunshu rushed around, desperately trying to patch up the formations, hoping to keep this plane going for a few more days, so more spiritual energy could be transferred into the Cloud Mist Mountain Array, minimizing the damage when the Hidden Sect World collapses.
In this way, they held on for a full seven days.
Even with Tong Yunshu's help, and despite the dual cultivation they squeezed in to recover their power, the prolonged draining of True Yuan caused by repairing the formation still left Yang Fei utterly exhausted, his internal power only maintaining about fifty percent.
