In the novel there are 13 Demon Kings and 12 Archangels
And seven of the thirteen demons kings are known as the Seven Deadly Sins
And one of the seven deadly sin demon king which we'll be facing now is known as--
--The Demon King Sin of Gluttony, Beelzebub!
Seeing us Beelzebub smiled and licked his lips as he said "Food"
Gritting my teeth I said "Stay focus, we need to wait for the right time"
Jeong Ji-ho and Choi Kwan nodded and I was satisfied as I thought 'So they already know that running away is useless against a demon king huh?'
Raising my sword I pondered and sighed as I said "Listen the both of you, after this fight no matter what happens now, you cannot ask my questions related to the fight got it?"
The two did not understand what I mean and asked "What do you mean?"
"Just swear it alright!" I was getting flustered because the Beelzebub was approaching step by step and so I exclaimed in a hurry
"Alright we swear!" Finally they also couldn't help it and agreed
Nodding my head I said "Alright, Jeong Ji-ho use your ability"
Surprised Jeong Ji-ho widened his eyes but before he could ask I said "You swore right? Now follow my instructions if you want to live!"
Jeong Ji-ho clicked his tongue in dissatisfaction and and took a deep breath before suddenly he was covered in golden flames
I then said "Choi Kwan"
Not expecting me to know his name he narrowed his eyes suspiciously at me but stil listened
I said "Use your ability aswell. You two buy me some time"
Understanding they immediately used their abilities and rushed towards Beelzebub
Beelzebub's multiple hands shot at them and they dodged and sliced some of it but it regrew back in no time
This is why Choi Kwan nearly died because of Beelzebub in the novel but it's also because of it that he found out it's weakness and defeated it
How you may ask?
It's simple (Not really). He got eaten whole by the mouth in stomach and just as he was about to be melted by acid he found that every time he stabs inside the stomach Beelzebub reacts but is still physically fine until he saw a very very small black dot inside the stomach and pierced it! That's when Beelzebub died
Ofcourse I won't let Choi Kwan be swallowed by that bastard so I had an idea
'System'
[Yes host?]
'Buy me that S - Class Bomb that you sell in the system shop'
[That will cost 56% of your health, would the host still like to buy it?]
[Yes/No]
Without hesitation I said 'yes' because---
I'm not the one who will be defeating that bastard
As the bomb that is the size of my hand appear on my hand I waited anxiously for the right time until finally I saw both Jeong Ji-ho and Choi Kwan reach Beelzebub
Finally I shouted "Choi Kwan! Catch it!" as I said that I threw the bomb at them using every single force and strength on that single hand just to reach Choi Kwan
Fortunately my luck was high and it did reached Choi Kwan!
Just as Choi Kwan catches it I then said "Jeong Ji-ho! Taunt Beelzebub!"
Knowing who I was referring to Jeong Ji-ho sneered and said "Fine, I'll do it myself"
As Jeong Ji-ho slashed more arms he walked calmly towards Beelzebub
Beelzebub became even more angry and send multiple hands at once towards Jeong Ji-ho
Jeong Ji-ho slashed the arms but was still caught until he was nowhere to be seen when suddenly bright light engulfed the arms that surrounded Jeong Ji-ho and was burned to dust!
Suddenly Jeong Ji-ho smirked and said "Is that all you got? Fatty"
Hearing the final word Beelzebub became even more angry and roared
Just then I shouted "Now Choi Kwan! Throw it in his mouth on his stomach!"
Hearing me Choi Kwan immediately leaped forward towards Beelzebub who was roaring and threw the bomb right in the center of the mouth
Just as Beelzebub swallowed it I yelled "Everyone get down!"
As I said that I dropped on the ground
Choi Kwan jumped back and hid behind a giant boulder while Jeong Ji-ho who was the nearest to Bweelzebub covered himself with a wings of a dragon made from flames
Beelzebub who swallowed the bomb burped before---
Shhhhhiiiiiing
Boom!
Suddenly with a large explosion Beelzebub was torn to pieces as the earth shook greatly!
As rocks were falling down I said "Retreat!"
Immediately afterwards when I saw them running towards me I turned around and was also about to run when--
Crack!
"Urgh!"
A rock hit my head and blood dripped from it
Suddenly I received a warning from the system
[Warning! Warning! Health is decreased by 10%!]
Hearing this I thought 'Fuck' and my vision suddenly turned blurry before I fainted and the last thing I heard was someone calling my name.
*****
As all of this were happening in the underworld the demon king heard the news about Beelzebub death and laughed as he said "Amusing, not only did he know about my plan but he also knew Beelzebub weakness?"
"Beelzebub cannot easily die by merely a sword or a weapon unless if it is in his stomach where his weakness the dot is"
"Who is this person? Is he omnipotent or something?"
"Or does he have a great constellation behind his back?"
"Impossible, no constellation is omnipotent enough to know everything"
Countless of questions flashed in his mind and he couldn't help letting out a chuckle as he thought 'I wonder if he'll imeediately notice my identity once I appear before him…."
"Interesting, I can't wait to find out"
