I feel lost when I travel through the world, and I look around and see no one but myself. It is hard to find the way in a foreign land, and the customs and people are all different. I don't know where to go, and the way back is thousands of miles away. Even if I feel lost, I still try to survive. Xu Wang, who traveled to the Gu world, has only one goal: everything is inferior, and he can live freely.
