The war in the Orc Empire ended in a rainbow rain, and Wu Yu also disappeared.
A child appears in the distant Yan desert. He has no memory and does not know where he came from. All his memories have been sealed away. The wandering poet's poems allow him to discover clues to unlock his dusty memories. He follows the tour group to the Blue Imperial Capital, hoping to find everything there.
He saw strange monsters in the desert, powerful priests in the Kingdom of God, and more unpredictable things, allowing him to see a more colorful side of the world.
