The 83rd edition of "Nine Shadows in Zhen Jing", Volume II, Episode II, Guo Jing got the human skin?

In the episode of Honglie Palace in Hong Yan, I found it on Guo Jing, which is 13 (53 minutes). In order to dress Hua Zheng's wound, he casually checked something on the ground, which happened to be skin! In that episode, Hong Qigong was injured and they were forced to the secret room. In order to escape, they also taught Guo Jing the other eighteen palms of dragon fighting. Zheng and others are also in the secret room.
