When the doomsday comes and civilization collapses, Yan Zhijin uses the cold flame as a blade to burn away all the hypocritical thrones, but alone in the ruins he meets Ji Zhuoyuan - a woman who can use blood as a guide to ignite the fire of death. She doesn't ask for salvation, but only for cause and effect; he doesn't ask for the way back, only for the flames. When the sky opened with a scarlet mouth, and when the tide of corpses turned into whispering gods, they walked side by side through the scorched earth, rewriting the laws of survival with the flames of burning the world. Not a savior, but the most vicious survivor. She burned the Doomsday Throne with cold flames, and he was her only burning point.
