The flames of war engulf civilization, and faith is swaying in the ruins. The Nancheng Nunnery has become the last refuge in troubled times, but it is also a cage where humanity confronts light and dark.
The young trainee nun Shen Huixin Sophie was forced to walk into the streets strewn with corpses in order to get a meal to survive. However, she was accidentally dragged by a "corpse" - a strange girl with clear eyes and ruthless methods.
"Take me into a convent, or you and I will die together."
A life-threatening deal was quietly concluded. Shen Huixin was forced to be involved in a dangerous exchange: using the life of the meanest elderly nun in the hospital in exchange for the protection and vitality of this mysterious girl.
However, when Shen Huixin stood tremblingly at the crossroads between conscience and life and death, she hid a clean nun's uniform and a killing blade.
However, the girl in the next life was reborn with the fragmented memories of the previous life...
Purpose: War is cruel, cherish the life you have now
