The peculiar creature earlier seemed to have the ability of infinite resurrection, but now it hasn't revived and reappeared near us. It seems the flame imbued with killing intent had an effect.
The power of the strange beings in the Doomsday Era seems to be much more bizarre than the anomalies I've heard of in the modern world. It's likely that they have undergone adaptive evolution to the environment of the Doomsday Era. However, even if they are strange beings of the Doomsday Era, they are ultimately anomalies, not entities that truly threaten the world. Although they have unique rules of the 'Undying Body,' Impermanence is a ground god capable of redefining the rules of heaven and earth, and I have no reason to believe I can't kill even this.
