Redo: Grimoire System in the Apocalypse

Geth crashed through the smaller Slimes like a madman and finally reached the creature. As soon as he was within arm's distance, he sent out a flurry of punches. He didn't rely on kicks due to the smaller Slimes surrounding him.

Each time a small Slime would come into kicking distance, he would send a stomp their way. In this manner, he continuously whittled down the health of the Level 5 in front of him, while watching the others that were inching ever closer.

As the Slime's HP hit 200, the core inside the Lord Slime suddenly shined with a blinding light, soon causing the core in the Slime he was facing to glow as well. It would release a faint pulse every 3 seconds.

With each pulse, its HP would be replenished by 10 points. 'Great! No wonder these fuckers reproduced so quickly, every time their HP became low from creating Slimes, they would be healed back up.'

The only thing he could do at this point was to allow the creature to deal damage to him so that he could punch faster. He had to outpace the healing effect.

He was managing to deal 40-50 damage between each healing tick and was only taking around 15 damage in return. It wasn't like the Slime could physically attack him, but its absorption capabilities were similar to acid eating at his skin.

By the time he'd finished off the first Slime, two of the others had managed to get in reach of him. Geth danced around them as best he could, dealing damage as fast as he could.

This was a bad situation for him. He was never in great shape, to begin with, his breathing was heavy, and sweat was running down his body.

'If I get out of this, I'm doing cardio every day. This is ridiculous.' Regardless of the similarities, this was not a game, it was real life. His back pain and the ache in his left knee were reminding him of that as well.

Ignoring the tiredness, for now, he worked to kill off the remaining Level 5 Slimes.

:Geth; HP‐ 316/500:

As the fourth Slime fell, he was not in the best shape. There were multiple areas of skin that had been eaten away, they looked similar to how spider bites would rot and peel.

If it wasn't for his recovery constantly stabbing over the wounds quickly, he would likely have bled out already.

There were very few of the Level 1 Slimes left, 20 at most. Just as he was about to face the last large Slime, a change occurred in the Lord. He'd noticed its "eye" blink rapidly, and then its HP dropped by 400 points!

:Lord Slime (Boss); HP- 1100/1500:

Then, two new Level 5 Slimes peeled away from its massive body. "Are you fucking kidding me!" He was already exhausted, one Slime was still easy, but now there were three again.

To make matters worse, the Lord Slimes core began to pulse and its health began to recover. The rate was the same as before, one tick every 3 seconds for 10 HP.

'Great, if it can keep casting that, then it will be at full health again in two minutes. If I'm quick, I can kill these three in that time, then I'd only have two to deal with at once. I should be able to deal some damage to the Lord on the next round of summoning.'

He sighed heavily, this was definitely meant to be taken on by a party, not an individual. Continuing to press forward he destroyed all three of the Slimes, along with the remaining Level 1's, in just slightly over 2 minutes.

The Lord Slime had already summoned two more helpers and began its healing process as he smashed his foot on the last baby Slime. Again, he started fighting the two Slimes as they ate away at his skin, opening many of the wounds again that were trying to scab over.

Blood littered the place, every time he swung his fists or threw a kick, blood would splatter out onto the ground. Geth was running out of steam.

He'd had an idea while finishing off the first of the two summons, but he wouldn't be able to implement it until the next round of creatures.

:Geth; HP- 207/500:

There were still had about a minute and ten seconds. He pummeled the last Slime to paste, leaving himself and the Lord Slime alone.

Not wasting any time, he rushed the Lord and started punching and kicking frantically. There were only 20 seconds left to do as much damage as possible.

While he was up close, he shoved the five spikes he'd crafted into the clear body of the creature. He jumped away as soon as the "eye" started flashing again, and he watched its HP plummet.

:Lord Slime (Boss); HP 879/1500:

Once the two new Level 5's left its body, the healing process began again. This time, Geth ignored the Level 5's and put some distance between them. He turned the ground beneath the Lord into mud and controlled a thick tendril to snake up into the Lord's body.

On its way up, he formed a rough hand that absorbed the five spikes that he had left in its body earlier, forming a claw... His Mana was dropping by 6 per second, he didn't have long. The Runes in his mind were scorching, the chill of his Mana struggling to cool them.

The hand snaked its way 12 feet up into the creature's body. Once he'd made it to the top, he used the claw to pierce the Lord Slime's "eye" over and over again.

Each time he did so, its HP would drop by a large amount, its healing couldn't even come close to keeping up. Each pierce would do between 50-80 damage.

He kept it up for as long as he could, the heat from the Runes had completely overtaken the Mana's chill at this point. Blood started running from his nose and eyes as his health started dropping quickly.
