Quest Walkthrough
1.Seek Out Mountain Shaper: Your first objective will be to seek out the adeptus known as Mountain Shaper. This involves traveling to Mt. Hulao, located in Liyue.
2.Travel to Mt. Hulao: Head towards Mt. Hulao. You can glide from a higher point or climb up from the base.
3.Find and Talk to Li Ding: Upon reaching the area, you'll encounter a man named Li Ding, who's praying or cowering near a small pool of water. He'll tell you about his brother, Li Dang, trapped in amber.
4.Shatter the Amber: Follow the path down from where Li Ding is. Look for amber crystals along the path. One of these will contain Li Dang. Use attacks (preferably Pyro for effectiveness against the amber) to break it and free him.
5.Return to Li Ding: After freeing Li Dang, return to Li Ding to inform him. They'll express their gratitude and leave.
6.Meet Mountain Shaper: Once the brothers leave, Mountain Shaper will appear, initially upset about the freeing of the "thieves". Explain the situation regarding Rex Lapis's (Morax) supposed death. This conversation will reveal some lore and conclude the quest's interaction with Mountain Shaper.
