Right at the decisive moment when even the strongest members of the party were struggling to cage this tyrannical being afront, Ervalen launched himself into the Hydra's mouth without a single moment of hesitation.
Swoosh!
Right when he reached inside the 300 meter long throat and slid downward, he quickly cast a protection barrier on himself while charging towards the stomach with all the strength remaining in his body.
Ervalen used the last remaining world energy he had stored in the artifact for summoners and dived inside the gate to hell as his last resort. Yet, his expression didn't have a shred of fear.
Desperate times require desperate measures.
This saying perfectly fit their current circumstances because they had no other way left after half of their party members were brutally massacred by this mythical rank floor boss.
