This world is divided into outside the wall and inside the wall. Outside the wall there are various mutant beasts with superpowers, and inside the wall there are people with superpowers and ordinary people.
Xie Buyi woke up outside the wall without any memory. She was discovered by two people without powers. They picked her up and took her to the third-class area where people without powers live.
Xie Buyi is not very interested in his missing memory. He only knows that he seems to be a low-level killer.
She was very happy living in the third-class area. She took the child she picked up and did tasks to earn points, and waited to be fed delicious food every day.
Until one day, the mutated bird outside the wall came to the third-level area. He killed it without hesitation and was noticed.
She suddenly found that there were many doubts about herself, and the people approaching her seemed to have other purposes.
She suddenly has to save the world.
Purpose: survive well
