Capítulo 256: War Conclusion .

The battlefield fell into silence as Fenrir's wounded body lay weakly on the hard ground.

He struggled to breathe, bearing the weight of multiple injuries. Strangely, his usual power of rapid regeneration was not working. 

For some inexplicable reason, the demon lords unleashed a power that seemed to dampen his regenerative abilities.

Initially, his healing process had been merely slowed down, but with the continued influx of this energy entering his body, the situation deteriorated. Now, his ability to heal was even worse than that of an ordinary human.

Despite the best efforts of other supernatural beings, like the dryad, they couldn't mend his wounds. 

Thankfully, the demon lords had also been dealt with before he finally succumbed to his wounds, collapsing to the ground on the brink of death.
