On the edge of the dark forest where wilderness and mist intersect, Youlan, a wanderer in the sand sea, wears a cloak of cracked quicksand and treks alone. He is not looking for gold or a way home, he is just looking for the legendary secret creatures lurking deep in the forest - those ancient shadows that have not been swallowed up by the night. The heart of the forest is ready to stir, and the desert wind whispers forgotten truths. You Lan is burdened with an unspeakable loss. His footsteps are like the traces of time, and every step is chasing the boundary between himself and the unknown. When the roar of mysterious creatures breaks the silence, and the sand and tree roots interweave the spell of life and death, Youlan must choose between faith and fear to uncover the mystery deep in the forest, or disappear forever at the end of the sand and shadows. The story sings of desolation and longing, showing a wanderer's lonely struggle between darkness and light, awakening the hopes and secrets sleeping at the end of the world.
