Henry quickly opened the coffin next to the one he had opened before. This time, instead of even waiting for the demon to wake up, he quickly stabbed right into the Hellsword's skull, piercing it greatly, as the Demon Slaying Energy disintegrated the rest of its body.

'This is your second chance. Disrespect one more of the dead and you will be punished.'

"Suck it."

Henry did the same to the third coffin in the room.

You have gained 1 Hellsword skull. Current quest progress: 5/40.

'This is it. You shall now be punished. Begone, intruder.'

Henry felt the pyramid shake slightly, and he felt a huge amount of mana emissions coming in his direction, causing him to get goosebumps.

"Damn, this is no joke. Oh, whatever. If it gets too dangerous, I'll use Null to get out of their immediate vicinity and run away."

Henry noticed the final remaining coffin in the room shake.

'It's coming.'

The coffin opened, and out came a Hellsword. Its burning skull seemed to be burning brighter than the previous three.

'The system did say something about a surge of demonic energy.'

Henry pulled out his gun and shot the Hellsword in the head, which stunned it, but wasn't enough to kill it. However, Henry had already experienced fighting the sturdy undead Hellswords, so he knew the shot wasn't enough to take down the Hellsword. Because of this, he chained two quick slashes after the bullet, taking the demon down.

He didn't manage to read the exp gain message, as he felt hordes of Hellswords rushing his way.

'I'll charge up a big strike to give as a welcoming gift to them.' Henry's sword glowed bright as he filled it with Demon Slaying Energy.

Soon, a huge horde of Hellswords was in front of the room's entrance.

'I'll use the narrow entrance to separate them and pick them off.'

Five Hellswords rushed into the room, each of them swinging its sword in Henry's direction.

Henry quickly unleashed the strike he had charged.

"Asura's Wrath Sword Technique, First Form: Cycle of Death!"

Henry spun around in the room, which was fortunately big enough to use Cycle of Death. He hit each of the five Hellswords about six times, as well as deflecting their strikes. He also activated Purging Chain Lightning while spinning, but it now had a twist.

'Demon Slaying Energy: Purging Chain Lightning, Fire Charged.'

All five burning skeletons were quickly engulfed in a jade green fire that chained between them, forming a pentagon of burning Hellswords.

'Hahahaha, that's satisfying as hell. I have to cut down on using Purging Chain Lightning, though, or I'll run out of fire mana.'

'Next.'

This time, Henry didn't have time to charge anything up, as seven Hellswords squeezed in through the door.

Henry immediately rushed towards one of them and tried to stab it, but it blocked with its sword.

"Dumbass."

With his other hand, Henry pulled out his gun and shot the Hellsword in the head, taking the chance to behead the stunned skeleton.

He then used Asura's Charge to jump another one, making it fall down, and stabbed downwards into its skull, crushing it.

Henry sensed two of the Hellswords trying to stab him in the back. He quickly sent all his thunderous energy into his back and turned around and managed to block one of the strikes.

However, the other stab had in fact penetrated his back.

"You motherfucker!"

Henry grabbed the Hellsword's sword, which was inside him, preventing the skeleton from taking it back, and shot it in the head four times, killing it.

'Shit, this hurts like hell. The demonic energy in his aura is burning me from inside.'

The Hellsword whose hit was blocked was now also swinging in Henry's direction, so Henry barely gathered his strength and rolled out of the way, then shot the Hellsword dead.

'I can't keep wasting ammo like this.'

More Hellswords were constantly walking in, so each second Henry stayed injured was a lethal threat.

He could just drink a healing potion, but the demonic energy would keep burning him from inside.

'Wait! Didn't Captain Eve purify the wounds of the injured with Holy Energy back then? My Demon Slaying Energy should be able to do the same, as it's also anti-demonic.'

Henry put Demon Slaying Energy on his palm and ran it over his wound.

'Shit, they're coming.'

The demonic energy was gone, but Henry wasn't healed yet. Of course, the Hellswords wouldn't wait for him.

Three of them were already in front of him, so he activated the combination of Cycle of Death and Purging Chain Lightning again, killing them.

He quickly took the chance and chugged down a healing potion from the inventory, and his wound started healing very quickly. He did, after all, have much stronger regenerative ability.

'Let's switch to Null's title. The weakening effect will be useful.'

You have equipped the title "Agent of Darkness and Nihility".

"Alright, now come here, motherfuckers!"

Henry charged towards one of the Hellswords, which didn't manage to block his strike, so it was knocked far away. Henry kept running towards it, blocking some hits during the way, and finally ran Dawnbringer right into its skull, killing it.

You have slain 1 Mephillian Hellsword. You have gained 300 Demon Slaying Energy Exp. Current: lvl 19, 1310/1900 Exp. You have also gained 30 Darkness Points.

'Wait, 300 Exp? Oh my god, I totally forgot about this effect! Hahahahahaha, it seems my Demon Slaying Energy will be equal to 5-star aura or something by the time I leave this place. Of course, that's if I even manage to leave.'
