"Hey what's this burning sensation I feel every time I level up?" Meurig asked.

"I don't know either, I find it soothing. I just assumed the system put it in place to make players grind through the world," Yuki responded.

Yuki and Meurig began walking to the next gateway.

"Hey, wanna take a short break before we head into the last stage of the dungeon," Meurig proposed.

"No need for that, I have a reliable plan for the next dungeon. Just trust me!" Yuki replied.

"Whatever you say chief," Meurig said as he rolled his eyes.

[Save point reached]

[If you would like to move to the 10th stage of the dungeon, please step forward]

[Stage 10 difficulty: level 5+]

[Warning: You cannot retreat from this stage]

Ignoring the warning, Yuki and Meurig stepped through the white gate. Meurig instantly regretted his decision to follow Yuki. In front of them was a large dark castle. Right at the entryway stood 500 skeletal monsters. Their leader was in the back. It was another flouting figure, much like the grim reaper he wore a cloak. However he did not carry a scythe. Instead, he moved his arms, creating glowing green spiritual patterns in front of his palms. When Yuki got a closer look at the monster, he could see that it was a skeleton with a large big smile on its face with glowing green eyes.

"So our final enemy here is the ruler of the undead, the one undead that stands above all others!" Yuki spoke.

[The immortal undead king of the undead Final Boss: Lich Feliu]

"So what's the plan now genius?" Meurig made a sarcastic remark at Yuki.

"I told you that I got this. Just stay back and watch," Yuki replied with a confident smile.

[Open inventory]

"Your plan is to drink a couple potions?" Meurig mocked Yuki.

"Not really, I plan to drink all of them," Yuki replied.

"ARE YOU INSANE?" Meurig asked as his mouth opened wide.

"Maybe, I don't know for sure," Yuki replied as he continued to pull out all the potions he had stored in his inventory.

"First of all don't you feel sick when you drink them? Secondly aren't they crazy expensive?" Meurig tried to convince Yuki not to follow through with his plan.

"For your first question, yes but I got used to it. For your second one, yes they are expensive and I wasted most of my money on them but it's okay, I earned more than enough from the 5th stage of the dungeon. This stage should also reward me for completing it too," Yuki replied as if everything was normal.

Yuki began drinking all the potions as fast as he could while the skeletal infantry began to approach them.

"Do you want me to hold them off until you're finished drinking?" Meurig asked.

"No need, you already contributed a lot in the last stage, leave this to me!" Yuki replied.

Just before the first skeleton soldier could make contact with him, Yuki pulled out "Niflheim's holy treasure" from his inventory and seemingly disappeared from Meurig as well as everyone else's vision. About 2 seconds later, every skeleton head fell on the ground simultaneously. Feliu began to get a bit worried which caused him to activate his ability.

[Cast Spell: Regenerate]

As if playing a video in reverse, all of the skeletal heads rose from the ground and attacked back on to their respective bodies. Yuki sighed and once again disappeared from everyone's vision. He sliced off each one of the skeletal heads however this time, he also attacked Feliu. Yuki sliced the lich seemingly hundreds of times.

"That should be the end of them," Yuki thought.

However when Yuki turned back, he could see the infantry heads rising and reattaching themselves. Before Yuki could even react something pierced through his chest.

[Cast Spell: Fire]

It was a blade made out of flames. Yuki quickly moved away from his enemy. Luckily the whole made on his chest began to heal automatically because of all the potions Yuki had consumed.

"I forgot you were immortal," Yuki told Feliu.

[Open inventory]

Yuki pulled out "Fallen angel of hell" from his inventory and just as he had done previously, he rubbed the edges of his two blades and engulfed them in flambes. He quickly teleported to Feliu and struck him with his two burning blades.

"How do you like that!" Yuki exclaimed.

[Cast Spell: Regenerate]

Yuki already knew that his plan had failed. Before Feliu could get a change to strike back, Yuki began to think of a strategy to defeat his opponent.

"The solution has to be provided within the dungeon or the purpose of the dungeon fails, even though Raza was immortal too, there were multiple ways to make a fire burn him. Think Yuki think!" he told himself.

Just then an idea came to him.

[Open inventory]

Yuki quickly returned both his precious swords into his inventory then proceeded to take out his newest blade "Scythe dagger".

"What is he thinking? that dagger is way weaker than his other blades, even without seeing their stats, it's clear that it is no competition," Meurig said as he watched from a distance.

Yuki quickly leaped on the wall of the entrance gate to the large castle. He propelled himself right in front of Feliu. While the lich tried to put up his arm in front of his face as protection, he was too slow. Yuki held the dagger with both hands as the tip of the blade faced Feliu. The dagger slid into Feliu's skull like butter. There was a delay for about 3 seconds until the lich's entire body began to crack and break. The skeletal infantry followed suit and proceeded to turn to dust.

"What happened? What did you do? How did you do that?" Meurig began to bombard Yuki with questions.

"What do you mean? It was simple, can't you read or something?" Yuki mocked his friend.

Meurig began to get visibly angry.

"Okay okay, relax I'll explain."

"If you read the power of the dagger you would know that it makes contact with the target's soul when it inflicts a critical hit."

"Since the lich is immortal, if something makes contact with it's soul and inflicts damage to it, a paradox is created and it forces the lich's body to self-destruct. Well at least that's my theory," Yuki explained.

"One more question, how were you able to inflict a critical hit on the first attack?" Meurig asked.

"Are you able to think properly? I stocked up on potions for this dungeon, of course I would have a critical rate boost potion. How else would I be able to do something like that?" Yuki replied.

"Even though you can boost your physical capabilities, no amount of potions could give you a functional brain," Meurig replied.

"Anyway we should be celebrating, we can finally leave this dumb!" Yuki said as they began to exit the dungeon.
