I can't figure it out in Chapter 4 of Xian Guo Zhi.

Hello, I would like to ask what should I do if the fourth chapter of Xianguozhi can't get through? Xian guozhi chapter 4 I can't beat this:

1. First, defeat Zhang Bao and Sean after solving the mystery in Montenegro, and you will get the "key to the remains cave";

2、? Then in the ruins cave, after using this key, you can open the originally closed door;

3. If the old man in Nanpi Village takes the branch task, then follow the instructions of the branch task;

4. Select "Zhang Ning" to join the team;

5. Following the progress of the main task, after Xiapi defeated Lu Bu, he left Xiapi City in the north and went to Beihai City for talks with the magistrate Kong Rong.

6、? After completing the dialogue, leave Beihai City, destroy Guan Hai, the general of the Yellow Scarf Army, in the west of Beihai City, and then return to the Taishoufu. Then you can find Yuan Shu dying at the gate of Mount Tai. ? After saving Yuan Shu's life, Yuan Shu will apply to join the leading role team, and then find the dying Yuan Shu at the entrance of Mount Tai, so that the task of Chapter 4 can be completed. Fairy Tale is a classic three-country RPG mobile game, which was upgraded on the basis of swallowing heaven and earth.
