Alessia and other adventurers were all doing a campfire party. Even the tired ones also had gotten enough rest and Alessia herself requested all the adventurers to attend this campfire party. Her prestige among the adventurers was great as she was the strongest among them. So all of them decided to attend the party.
There was a huge campfire burning in the middle of the campground. All the adventurers were standing close to the fire with mugs of booze and food in their hand. Alessia spoke up -
"Guys, this is surely going to be our last day inside this dungeon. This is definitely a demigod rank dungeon as there are monsters over level 400 here.
I never imagined even in my wildest dreams that we can have such a relaxing party inside this super dangerous dungeon. But here we are doing it.
It's all thanks to Elena Onee-sama. She is definitely going to destroy the dungeon core today and our dungeon diving will come to an end. This was one of the shortest dungeon dive which only lasted for 3-4 days but I will never be able to forget it.
During this expedition we all improved a lot. We all can beat our previous self from before entering the dungeon easily now. Which is also thanks to Elena Onee-sama. She protected us, guided us, taught us and even gifted us various things.
But, what have we done for her? Nothing. Absolutely nothing. We all are way weaker than her so we can't do much but I still want to atleast somehow show her my gratitude. What do you all think? Don't you want that?"
All the adventurers loudly replied-
"Yes, we want to thank (miss-) Elena (-Onee-sama) somehow."
Alessia said once again-
"We are no match for her in strength or in other aspects. So we can't show our gratitude by helping her in something as there is nothing we can do to help her.
So I thought, how about giving her a surprise party which we all can prepare with all we have got. She is not a petty person and doesn't need extravagance so I think if we do our best, then that will make her happier. What do you all think?"
All the adventurers look at each other and Rishia came forward as a representative and said-
"What is there to even think about. I obviously want to make Elena Onee-sama happy so I will do my best. And if anyone disagree than that person is an ungrateful scum unworthy of living."
Hearing her some adventurers looked away guiltily, that didn't miss Alessia's eyes but she didn't do anything to them for now. Most of the adventurer agreed with her and they finalized the plan for a surprise party for Elena. After that they started the campfire party.
As the party was going on the full swing, Elena suddenly appeared between them. She said-
"Oh it looks like you all are having a lot of fun here."
She had another little girl with her, whose head she patted and said to her-
"They are the ones who came to the dungeon with me."
She then told to the adventurers -
"This girl here may look like a small kid but she is actually older than you all. Her name is Armouvista. She was captured by the dungeon master here so I saved her. Vista, say hello to them."
Vista bowed her head and spoke up -
"Hello everyone. I'm Armouvista and I'm very glad to meet you all. If any one of you have any trouble, you can rely on me."
"Yes, by the way, she is stronger than a S rank adventurer so you all should be careful about that fact."
All of their jaws dropped to the ground hearing that this little girl was stronger than a S rank adventurer. That could only mean, she was a demigod who were Legendary existences. But in the last few days they had already seen many legendary things so they accepted it very fast.
Vista had a quite cheerful, bright and gentle personality so she was able to easily integrate herself with the adventurers. It was found out that she was quite a big drinker and in a blink of an eye she was having drinking competition with other members of the expedition.
As the time passed many of the adventurers were returning to their tents to rest. When the campground was almost empty and most of the adventurers had gone to sleep Elena approached Vista, feeding her a candy and asked -
"How do you feel after getting freed? Fufu, look at you smiling so happily."
Vista smiled shyly hearing her and hugged her tightly -
"Thank you very much Elena Onee-sama. I never thought I will be able to have fun like that once again. You not only saved my life but also saved the life of my thousands of citizens. Really really thank you very very much from the bottom of my heart."
As Vista was almost crying Elena rubbed her tears. She had not only destroyed the dungeon master and the core but have also stored all the Living Armours in her Mini World.
She got this Mini World as a gift from the world TIRTANYA. She also got a lot of supporting items to develop the world too but she haven't done anything with it as she didn't need it for anything so far but this time it came in handy.
The soul of all of her citizen were trapped inside those Living Armours monsters. This was done by her World's corrupted Will and the Devil King. So Elena didn't kill any of those 10000+ Living Armour monsters of the fifth floor instead took them inside her Mini World.
Vista actually started sleeping on Elena's lap after crying for sometime. Marina came to meet Elena as she was the last one still awake and got a bit jealous seeing Vista sleeping on Elena's lap. Elena smiled heartily seeing this and pulled Marina's head onto her another free lap and started patting her head too.
Even tho Marina felt very embarrassed she was very happy deep inside too and she also lost in the comfortable embrace of sleep soon after.
And that is how the last day inside the dungeon ended.
...
The next morning, all the females specially Rishia and Alessia were giving Marina death stares. They all got super jealous after seeing Marina sleeping happily on Elena's lap. Marina actually had the best sleep in her whole life on Elena's lap even tho the position she slept should have been painful. Elena pacified the disgruntled pair and other dissatisfied girls and then they finally left the dungeon.
Elena told everyone that the dungeon would get completely destroyed in about 2-3 more days. As the proof, they had the destroyed core but Elena would actually not give this core to the adventurer guild and directly hand this over to the Supreme Goddesses and they will take care of the rest, like notifying the guild and temples etc.
After getting out of the dungeon Elena didn't let the expedition team walk back towards the city instead she directly teleported them a bit far away from the south gates. After seeing the walls of the Frontier Guardian Rin infront of them, the adventurers finally felt that the expedition was over and shouted in joy -
"We are finally back after successful Dungeon Conquest."
