Yuki's three enemies were riddled with injuries, however they managed to exhaust him and he soon lost all of the power-up coming from his magic, and Yuuki took advantage of this opportunity and used his unique skill to disable Yuki's abilities one after the other...!

Diamond body, elemental resistance, and so on were deactivated one after the other, but some abilities he wasn't able to affect such as immortal stand which was one of the reasons Yuki was able to fight for so long despite his accumulating injuries…

'Goddamn it, those curses keep weakening me and the aura of corruption keeps getting blocked by these bastards. What should I do now? At this rate, I might actually lose especially since my base attributes without magic aren't as good as theirs...' Yuki was starting to feel the pressure from fighting these three monsters that were all at the disaster grade.

At the same time, the trio that were fighting him were also starting to regret their decision of picking this fight as they communicated telepathically 'We need to finish him off today or he will end up as a huge threat to us in the future' Said Kagali and both Yuuki and Laplace agreed with her

'He's running out of steam and will soon fall down, don't worry' Replied Yuuki with a cold look in his eyes to hide the fear he was feeling, for one moment there he was about to go all out and transform himself into a saint but he held himself back just in time…

Suddenly, Laplace disappeared at a terrifying speed and stabbed Yuki deeply into the abdomen before he quickly retreated to avoid his counterattack…

"Hehehehe, finally I got you with a good attack, now you have no chance of escaping this place... I wonder if Kagali can make a good death-man from your body" Spoke Laplace eerily and both Kagali and Yuuki also let out sighs of relief seeing that they finally caused some serious damage to his tough body...

Meanwhile, Yuki stared at his wound silently before he closed his eyes and activated both his lucid mind and absolute focus to unimaginable degrees for one purpose, and that's to powerup his wicked thought ability that focused on only one thing right now, and that's to kill the three people in front of him.

Countless wicked ideas flashed through Yuki's mind to the point that time seemed to stop, and his higher intelligence suddenly caused him to enter a state of enlightenment to the point that notifications kept sounding in his head rapidly as he thought about the only way he had to win this fight…

While Yuki was standing still with his eye closed, the trio attacked him multiple times once more causing hideous injuries to the point that his bones were showing in multiple places, but Yuki kept ignoring them until he suddenly opened his eyes and stared at them coldly, then in an instant, he activated all of his empowered skills which he was saving up to this point so that Yuuki doesn't deactivate them!

'Sword aura, Dark strike, Desperation strike' the three skills activating at the same time caused Yuki to unleash a dark and sharp aura from his body that accumulated on his sword that reeked of despair, and before the trio could even think of reacting, he simply disappeared from their vision and unleashed three terrifying slashes at them that broke through their barriers and created a huge gash on each of their bodies…

Yuki breathed heavily, and without even waiting to see the result of his attack, he immediately fled the scene and ran away from the free guild's destroyed building with his injured body…

Once he left the magic barriers, his power started to return to him slowly so he ran even faster as a result and the people of Ingrassia only saw a dark blur that was dropping dark tainted blood from all the curses that bastard Kagali used on him…

After leaving the capital of Ingrassia, Yuki found an empty place hidden by the trees and fell face first there

"Damn that Yuuki, he can actually seal skill and abilities easily… What kind of broken unique skill is that? He also doesn't take any damage unless it's purely physical or a mix of multiple powers… Tch this one was very close… But at least they had it worse than me" At the end, Yuki couldn't help but smirk slightly at the thought of how his aura of corruption managed to cause further injuries to them before they deployed more barriers to stop it once more, and it was the only reason he was able to escape…

"Hopefully my abilities will return to me soon so I could regenerate quickly… I wonder what's happening in the federation…"

While Yuki was muttering this, a little girl suddenly fell in front of him accompanied by a notification from the system…

…

Back at Tempest, they already started sustaining casualties from the high-ranking members, and the first to fall was unfortunately the previous goblin elder Rigurd who used his hulk-like body to protect some kids and female goblins that were attacked by an otherworlder…

This not only caused the battle to become even more difficult for the people of tempest but it also made them slowly fall into despair, especially Rimuru who cared deeply about his people yet he was forced to watch them die one after the other and ended up entering a crazed state in his fight against Hinata...

Kayle and Sacha were soon discovered as well, and Kayle tried to reason with them by showing them the emblem of Leon but the otherworlders didn't respect the reputation of the demon lord at all. Instead, it ignited their desire to harm them even more, especially when some of them were attracted by Sacha's beauty…

"Gentlemen, we are really demon lord Leon's followers, if you attack us it might end up in a bigger war than this" Spoke Kayle elegantly but he only received a punch by a young man who sneered at him and said "I don't care, I will just kill Leon if he ever dares to come out of his little city"

Kayle stared coldly at the otherworlder that held Sacha by the hand and was trying to take her inside of Yuki's house, his desire was clear...

'Geld, Gerdal, and Gerald are all occupied fighting otherworlders, and Dariun has yet to recover… At this rate, Sacha-chan might get hurt, and I can't imagine what will happen to me if that bastard comes back alive and finds out about this which I'm sure he will…'

After reaching this point in his thought, Kayle let out a sigh and stood up calmly while dusting his clothes...

"Kayle, ran away, don't bother with me" Yelled Sacha and Kayle could see the absolute fear in her eyes yet she was still thinking for his sake

"What a silly girl, it seems like I can't live peacefully anymore" Muttered Kayle calmly and the otherworlder smirked at her sadistically and said "You should be worried about yourself rather than about that old man-"

But suddenly, the otherworlder found himself staring at Kayle who was standing right behind him and he couldn't help but smile and say "Oh, you want to get punched once more?"

The otherworlder tried to muster his strength but he suddenly felt like he had none, in fact, he couldn't move his head or body at all and felt completely paralyzed which terrified him, and Sacha who was standing behind him couldn't help but cover her mouth in shock and said "Kayle-san?"

"Let's go Sacha, I will try to protect you to the best of my ability" spoke Kayle before he turned around and left the house and Sacha followed after him while still shooting that otherworlder a shocked look

"Where do you think you are going I-I…" He struggled slightly before the air finally stopped reaching his brain and he died a miserable death… to the last moments of his life, he was still unaware that Kayle had actually broken his neck and twisted his head backward…

"Are you really Kayle-san?" Asked Sacha warily while staring at the seemingly fragile old man easily dispatching an otherworlder with his bare hands skillfully and Kayle paused slightly and said "I'm still the Kayle you've always known, you are just going to see a new side of me"

Right after he finished saying this, a pitch-black bow appeared in his arms along with arrows made of pitch-black darkness, and he started shooting at the invaders which fell one after the others, and what was even more surprising was that whenever an area was clustered with only his enemies. Kayle would cause those bodies to explode creating even more casualties…

This was the man once known as the Black Death, a legendary assassin that suddenly disappeared from history without leaving any traces… Who knew he would end up as a normal butler in a demon lord's castle…?

…

With the addition of Kayle showing his true power, the tides of war took a better turn, but it wasn't enough since there were simply too many enemies and Kayle was soon confronted by a terrifying mage from Falmuth, Razen!

"Step back Sacha, It seems like this old man has finally found someone worthy to fight him" Spoke Kayle while staring at Razen, the chief sorcerer of Falmuth and a disaster grade individual!

"Black death, I never expected to see a legend like you here… If you wish to leave, I don't really mind, our invasion is just for these monsters" Razen didn't want to fight Kayle because he was one of the people that lived at the time when Kayle was active and he knew just how terrifying he was so he tried to avoid the fight if possible…

"I'm sorry but this little town is the home of my master, I can't leave and let it fall otherwise my old bone won't be able to handle his wrath"

"I see, well that leaves me no choice then" Spoke Razen before his gaze turned cold and said "Nuclear Cannon"

A terrifying blazing orb of nuclear magic was launched at Kayle, but he calmly waved his hand and said "Shadow portal"

An even bigger wave of darkness covered the nuclear cannon and not long after a huge explosion was heard in the distance…
