Dungeon System Within DanMachi

Tsubaki : Are you serious??

Seo : Deadly... In fact, i'm here to court Hephaestus...

Tsubaki : Hahahahaha... By what owning her??

Seo : No... By changing her life...

Hephaestus : Wait, so you weren't joking when you said you wish to go out with me??

Seo : Why should i joke... You are a unique beauty... I would be nuts if joked about it...

Hephaestus : Then what do you need these for??

Seo : My wedding gift to you...

Seo : You will see it later... Do i have to take an oath to believe me??

Hephaestus : Sure go ahead...

Seo : Ehh... Really an oath...

Seo : Should i go... with a simple one... An Absolute one or eternal one??

Hephaestus and Tsubaki were shocked when they heard about what kind of oath they wanted for him to take, they couldn't believe that this guy knew them...

Hephaestus : Did Hestia told you about those??

Seo : Nope... And i decided i will take the World Oath....

Seo : I Seo Riveiron... Pledge by the ancients Chaos that gave birth to the laws of this world and be a Judge for my own commitment towards Hephaestus and Tsubaki Collbrande...

Hephaestus : STOP!!!!!! RIGHT NOW!!!!

Tsubaki got paled, when she felt the power behind the oath and when she heard Hephaestus scream like that as she released her divinity she knew something bad was about to Happen...

Blackie stood there watching everything with amusement and a smile in her small face as she was thinking truly interesting...

The Divinity of Hephaestus clashed with the energy of the oath and almost blown her away as the floor and walls cracked together before they heard him finish his oath...

Seo : I vow, to change their world for their chance in return... Should i Fail this let my board be reset and the curse of the 100 Laws befell me...

As if the world started laughing at such a ridiculous vow... Chains started sprouting from thin air and surrounded him before they vanished...

Hephaestus started to tremble when the world chains appeared and so did Blackie as it suppressed them...

All three saw a smiling Seo looking at them without a care for what will happen to him...

Hephaestus : Do you know what have you done!!!!

Seo : Sure i know... I'm asking for both of your hands...

Hephaestus : Now... I truly want to see how you are gonna make me go out with you...

Tsubaki : What's with that oath...???

Hephaestus : If he fails to complete it... His board will reset not to level 1 but 0... Then he will get the wrath of the world...

Seo : Each time i would need to level up i would need to beat something twice my level...

Tsubaki opened her eye wide open as she realised what it meant... In order to reach Level one, he would need to beat a level 2... For reaching 2 he would need a level 4 and so on...

But none of them knew he had his hidden board as well reaching 2 levels higher than normal...

Hephaestus : Furthermore he would need 100 more experience than others to reach his limits before levelling up...

Seo : Now since I've shown you how serious i can be for a girl can we move on???

Tsubaki started smiling and so did Blackie they now had turned their full attention to him as they had never met such a crazy and interesting person before...

Hephaestus handed over the vials and what followed was something that almost caused her and Tsubaki to puke blood from regretting giving them to him...

They saw him drinking and eating them as they were simply food and water...

Seo, on the other hand, wanted to puke as well cause these billions like materials tasted like pee and shit to him...
