Where is Zhang Xiaofan in the main task of Zhu Xian 2?

The mission of killing immortals in southern Xinjiang needs you to find Zhang Xiaofan. Actually, you can't find him. When you reach 100,000 mountains in southern Xinjiang, you can go up the stairs directly to the tree house, with the top house of the wooden suspension bridge in the middle. There is an NPC in front of the house, and the back is gray. You can shake it in front of the NPC (Zhang Xiaofan's men), and this NPC will tell you that the lonely back of the deputy leader is ok.
