It's been a while since I have started existing, despite being clueless about this world my core contains some innate memories, resulting in having a knowledge that I have never acquired

  I had no materials to work on, my dungeon only consists of 3 floors, the only creatures that were here were little worms, I decided to share a fraction of dungeon miasma and made them much bigger in size, compared to their tiny selves they are now big and numerous, they are useful to say the least because their food is rock, they nibble on hard rocks, somehow digest them and expand my territory, other than that, I am lacking the army, it's worrying

  Some time ago a whole tribe of goblins appeared in my dungeon, I was worried at first, if they are hostile there's no way I can handle them, but if they settle here, it would be very beneficial, so they did and I was happy

  They are stronger than my worms, I decided to receive the guests with hospitality and grant them most of the available options, they should be lacking a night vision so I granted them skill in the dungeon shop, if they want to earn it, they have to defeat invaders, honestly my dungeon did not have invaders yet, but it's fine, I can use this time to grow my dungeon and reinforce it

  But then something happened that should not have, the strongest one, chief I assume moved to the second floor and tried to enter the third one, then I noticed that its mark turned red, it was hostile, sensing danger I reinforced the entrance to the third floor with a barrier and forbid it from entering, but I did not have enough time, the barrier was shattered by wall of flames that were raised exactly where my barrier stood, increasing the damage dealt immensely

  This is very bad, why did it decide to attack alone? It's level 14, I can't handle it with my guardian, I have to do something

  I made sure that everyone got such notifications, meanwhile I have to stall for time, but my guardian which is merely level 7 won't hold off for long and if he approaches my core... then I'll be done for sure, seems I have no choice but to use my dungeon miasma to make my guardian grow faster, but... will it be enough?

  Good, with the bonuses that it has it should be able to win me some time until they appear

  - Call for help, I dare you!

  I heard the voice, the chief was approaching with his staff, it chanted some spell and shot fireballs to my direction, ah, he's trying to make my guardian sacrifice itself to get rid of it, but I have my safety measures too

  I'll be fine for a while

  Earth worm dived into the mud and stone, grinding them in the process and swam in the ground, chief was vigilant, after all, even if its level is low, it can harm him due to many buffs that my dungeon granted it

  My guardian attacked from the ground, but it was caught by neck... oh no...

  It is being attacked by fireballs, NO, my guardian! You will pay treacherous monster!

  It wriggled in order to free itself but it did not have much fighting capability, it soon... perished

  I don't have that much time, I hope it works, treacherous monster, if you think you have won, then you are wrong, your power, your position is envied, you will perish by the hands of your own henchman!!!

  ...

  ...

  Finally they are here

  POV change

  I hurriedly went up to understand what was going on, my chief was fighting against the dungeon... but the quest also appeared, if I join my hands with Gnar and receive dungeon miasma we might have the chance against chief, how long has it been that I wanted to be the one to taste girls first, have jewelry and order everyone to my heart's content, I HAVE TO BE THE FIRST!

  The time has come for me to ascend to the position of chief

  - Gnar, you know what to do!

  - Roger, our chance has finally come, we are fed leftovers and have to be content with it, it's time for the rules to change!

  - Roar!

  - ROAR!

  POV change

  Finally, they show their true colors

  Dungeon core is too precious, it was a wise decision to expose them, I have been discontent with their greed and performance for quite some time, not to mention they have been hiding '' them '' from me

  The time has come

  I stopped hitting the dungeon cocoon and looked at my two guardsman whose skins turned red

  You are not to be forgiven, you shall DIE for disobeying me!

  - Time to pay for batreyal!

  I yelled and fire swirled around me, my skin turned red and it also started sizzling

  - Roar! Eat this!

  POV change

  I ran up, the dungeon was calling for help, once I entered the 3rd floor I saw the guardsman and chief fighting, what's going on, who's the intruder? How can they contend with him with their low levels?

  Is there time for inner fighting? They are facing some two headed giants, how can they fight at time like this?

  Gruntar exposed his bare chest, probably not wanting his clothes to catch the fire, Gnar also did the same

  I was seriously confused, goblins also did not know whose side to take, they were afraid of both sides and taking the wrong side would result in rebellion and death if their side failed, so they kept being quiet, I also stood there unmoving, watching the battle unfold

  Guardsman were strong, they covered their weaknesses by combining their strength and landed a hit or two on the chief, soon their bodies were sizzling and burning but they fought and fought until the bitter end

  The more they attacked the more vicious they got, especially for chief, as he was covered in green liquid and I thought him to be losing, he managed to grab Gruntar's sword with bare hands and smashed it on the ground, then grabbed his hand badly mutilating it, seriously where did this strength come from? Was not he a priest?

  The whirlwind of fire encompassed them and chief's staff let out a bright light, catching the falling guardsman in the ball of fire

  They still stood up like zombies but to no avail, chief was a monster, despite his lacking physique and staff that could hardly win against sword, he was an absolute monster, playing around with his guardsman, soon they did not move and after gulping down the high grade potion his wounds mended almost instantly, his guardsman also used one but I guess they were of lower quality and could not deal with burnt skin

  POV change

  Finally, these are mine

  I said inwardly as I stored two necklace like objects in my robe

  Now time to deal with him

  - Fireball!

  Soon the barrier broke and I got to taste the core of the dungeon

  Tasty~ Now these ettin bastards won't be able to lift a finger against me, I will crush them!

  POV change

  I expected this outcome, but I still don't get why did they fight? Was it for that big mana stone? Was it related to dungeon?

  Ah, could it have been a dungeon core? I expected more of a reward, but oh well, it's fine, there's nothing to see here, I better use this opportunity and hunt some worms, since dungeon no longer exists chief should not have access to our stats right?

  ... So they don't have cores anymore? Ah, what a pity, and here I thought I would get rich all of a sudden

  So these assholes no longer exist, who will take their position? Not me, most likely, so I don't care, I will still go and check whether these worms have left some mana stones

  ...

  They did not
