Even though Gudong put the bamboo basket mask on Ning Zhu's head, she was still recognized at a glance.
Just as Gudong had said before, how could someone familiar with you not recognize you just because they can't see your face clearly?
Ning Zhu was taken away. Gudong wanted to help but was helpless against the other side, so he went to find the Undying, who was in trouble at the time—a ghost from another world had found him again and seized his Thousand Lights Ming form, leaping from branch to branch, with wooden vines emanating from their hands.
The Undying had grown much compared to before, with the form of a white-haired youth, dodging the attacks from the wooden vines, summoning a long spear to fend off the wooden thorns.
But compared to the agile "Thousand Lights Ming" wooden vines, the Undying's movements were evidently slower, and his attacks were disorganized, making his defense very difficult.
So, he transformed into a giant bear.
