"Fèixū zhī Dié" is an original song featuring Yuezheng Ling and is the sequel to "Zhànchǎng zhī Huā". Ling sings how the world became meaningless after Tianyi protected her from the bomb. She continued fighting through her grief, saying that she lost any remaining shreds of mercy and kindness, and her motivation came from the fact that she is the last one alive and the only one who would remember what happened.
