In this chapter, we learn that xiaoya is just a normal human being, and that she will die when she gives birth to a baby girl. The baby girl will be born in the future, and the present will disappear. This is called a "time loop," and the world will only be able to move back and forth between the present and the future. The only way to escape this loop is to have the baby girl die when it is born, and then have a new baby girl born between the years 2001 and 2017. This is the only way that the world can move forward and backward in time. It's impossible to save the life of a normal person. It seems like you're clueless about what's going on. You're just absorbing vitality from other living beings. You don't know why your mom died. It was because you took away her vitality to create a time spirit. The road leading to the town is crumbling, and there's no other way to get there. So they stay and wait for the townsfolk to realize that the bridge ahead has been broken. Then they'll figure out a solution.
