The nightmare comes and the world falls. Human beings have built high walls to trap the last civilization within them. The untouchable areas outside the wall are the abandoned children who are regarded as "nutrition" by default.
Xu Yi is a person who is defined as "nutrient".
He eats his nightmares and feeds them to the monster inside him - a doctor who can dissect fear with a scalpel.
The doctor said: "Every time you become stronger, a part of you will die."
Xu Yi looked towards the high wall.
"Then tear the wall apart before I die."
