After receiving Wu Xin's task of finding materials for casting swords, he got the treasure map from Ding Xun and went to Wu Yungu again. He found a mysterious cave in the valley, where he could find Pangu axe, animal armor and flint. It is best to prepare a lot of food and herbs before entering the cave, because there are a lot of tiger dumplings and good wings in the cave, especially good wings, which are very offensive and defensive. Try to avoid confrontation, try to eliminate them one by one, and reduce your own harm. After finally escaping from the cave, Song Ji and Ding Xun stopped in front of you and asked you to leave a treasure. It turned out that all this was a trap designed by them. They use you to get the treasure, and then they make a profit. If I had helped Ding Xun find a doctor in front, Ding Xun would have found his conscience here and left voluntarily. So you can focus on Song Ji. After defeating them, the mission is over. Task reward: Pangu axe, beast armor, flint.
