Byou
Land	Mon-chien
Location	Ping-chao, the Palace of Dreaming
Role	Lost Soul

Byou (ビョウ) is one of the creatures that Rin can reincarnate as in Eastern Mind: The Lost Souls of Tong-Nou. Byou is born in the Land of Dreaming, bearing the mission of replacing Zuo-mong's defective eyeball with a new Eyeball of Dreaming using his Wrench.

Mission

Byou is born in Mon-chien, the Land of Dreaming. He must walk to Ping-chao, the Palace of Dreaming, so he can speak with Sui-gyou and Zuo-mong. Here he is informed that a new Eyeball of Dreaming is located underneath Mingke-shu. After acquiring the Eyeball of Dreaming from the deepest layer of the tree, Byou must return and install the new eyeball on Zuo-mong.

Walkthrough

Go to the Palace of Dreaming. The simplest way to pass Ah and Ung's riddle at the entrance is to answer "Golden Flower", other options include giving them something golden or using a Hitogata. Once inside, head to the center where the king and his apparatus are and talk to them. Optionally, a Peach can be acquired in this room by clicking the cage in the back-right corner and informing Sui-gyou that the red twin from Thi-eng is named "Ying". Go to Mingke-shu and distract Moku-gyou with an Ant or a Koma to enter the tree through his open mouth. Once inside, pick up the Wood Magatama if not already acquired and click on the tree's exit. Moku-gyou will appear and ask who the owner of the eyeball is, the answer being Tou-gyou. After this Rin will be granted passage to the deepest part of the tree, where the Eyeball of Dreaming pulsates in a wall. Pick it up, return to the Palace of Dreaming (which can be done quickly by spinning around outside the Tree of Life until Sui-gyou's face appears on it), then use the Wrench when prompted.
