The old master has been seriously injured, and the old master's sister has been missing for days. She must have been in collusion with the disciple yun xiang from the sect. The old man's condition is so bad that he has returned to the sect with his life on the line. The demon sect wants to end the war, but the old man is afraid that the sect will try to make yun qiang disappear in order to prevent him from returning to the land of his birth. He suggests that they use a mushroom from the back of a mountain to treat the injured man. The heroine is horrified at the idea of risking their lives for the sake of a man they have no choice but to protect. She says that she herself has seen a shadow walking on the cliff one day, and she is afraid of ghosts, so she has to go to the back to borrow the mushroom.
