The task of breaking the mirror of the Dongxuan Peeping Machine will be taken after we open the Hand Shaoyin Meridian and the Hand Taiyang Meridian. This task can also help us enter the sect.
We must first follow the mission prompts to climb to Taiping Golden Summit and look for Yinxian Rock. Both places are in the same direction, in Taihe Mountain on the big world map.
We teleport directly to Taihe Mountain and follow the map to the vicinity of the destination house. There will be two NPCs, Li Heku and Wu Ping'an. Talk to them to trigger the mission, otherwise the breakthrough mission will not be completed.
After repeating the conversation with them several times, we need to find the senior brother near the waterfall. Go directly to the right side of the map and find an NPC named Ying Bufan to have a conversation. After the conversation, we need to click on the scroll on the mountain below. . At this time, I discovered that there seemed to be a cave behind the waterfall.
At this time we need to use Qinggong. Press F near the cliff to fly to the stone on the right.
Fly to the rock in front of the waterfall, we can continue the task and choose to cross the waterfall directly.
After crossing the waterfall, I discovered that there was indeed a cave behind it, and there was an old man named Huang Dongxuan inside. After having a second conversation with him, complete the breakthrough mission.
