Inside the eldritch beholder, Jack continued to rain one attack after another. When the eldritch beholder tried to forcefully blow him out, the dark energies became thin. It slowly built up its density again since then. It was now as thick as before and maybe even more. Jack's HP was going down at a dangerous rate. If not for his insane recovery speed boosted by the Life Elevating Art, his HP would have been zeroed long ago.
Unfortunately, Life Elevating Art was nearing the end of its duration.
"I guess it's time for me to leave," Jack said. He couldn't see the eldritch beholder's HP bar from inside here. He hoped he had reduced the monster's HP enough.
When Jack first entered the eldritch beholder, she had clamped her mouth shut to trap Jack inside. Midway through the unending torture Jack brought about, she opened her mouth, trying to drive Jack out. When she failed to do so, she continued to leave her mouth open, in hopes that Jack would leave by himself.
