Go toward the Muttering Forest and find Waterstone. After you release Water Energy by Waterstone, tell the news of it to Yilian Zashu.

Description

I must request one more thing from you, . Lately, because my demeanor has affected the creatures in the area, especially that Ent, Yilian Zashu, who has been my companion, and this has caused me to worry.

If you take this Water Energy outside and go toward the Muttering Forest, you can find Waterstone at the pool. Release Water Energy beside the Waterstone, and once you have done that, my powers will begin to wash away impurity. Then, the living things will be at peace, and they will be able to grow smoothly. Then go deliver this news to Yilian Zashu.
