Something very important is missing. Here's the thing. Can you get it back?

Yi Gua: Like a hedge, the two hexagrams change, going up north and down south. Near the south of the fence. Go find it.

It's like digging a hole in the south of the hole and finding it.

Then, like a sewer grille, look around.

The two hexagrams have changed, and the two words are: Ritual, blowing Qiu Yi, and recruiting fierce people.

Note: Brush the path to Qiu Yi, where the mound is convex. Brush off the dirt and you will see something.

Good luck to you.
