Marvel: Stark Tower Dungeon

Arthur had finished a few small missions and side missions after he was sure that Emilia and Rem could use the transporter.

They could come and go to his base. They could even ask for assistance from android bots that Tony would transfer them here from the moon.

They basically had the right to command an army of high technology robots!

Forget about being selected to be the king of the kingdom of Lugnica.

Emilia could conquer the whole world if she wanted to.

Arthur looked at the dp that he had right now.

Dp: 25

It wasn't that hard for him to hunt thousands of monsters in a short time.

He hunted monsters and the witch cultists with Sylvie in her dragon form. 

The side mission of the first floor was usually related to the witch cult.

And he believed that they would be wiped out by the dungeon climbers sooner or later.

Just him hunting them down already trimmed down their number significantly.

"Dragon breath is really something…"

Arthur looked at what happened. The land was scorched and there was nothing left, only ashes.

Sylvie was very happy that her papa was super strong.

"Papa is so strong Woo hoo!"

Arthur thought dragon breath was just normal magic for dragons. 

Who would have thought that its destruction was on par with that of the great fire annihilation Madara had used.

With that result. 

He had more than enough dp to go to the second floor.

「Let's go to the second floor. This floor is too weak for us now. Your parameters isn't even going up anymore. And the dp and fp from the mission is astronomy low. One monster is equal to 0.00001 That is daylight robbery」

Great Red said with both feeling of excitement and annoyed at the same time.

Annoyed because the more monster that Arthur hunted the less dp and parameters he would get.

He couldn't be infinitely stronger just by grinding on the same floor. 

Excitement because he wanted to know what would await them on the second floor.

And as a dragon he also wanted his partner to be the first one to achieve the first to go to the second floor.

Ophis added.

「Yes, you should go there as soon as you can. I think you will get a reward for being the first one to successfully climb to the second floor.」

Arthur nodded. 

He got their souls and consciousness from the reward of being the first one to step inside the dungeon.

He really wanted to know what he would get from being the first one to step on the second floor.

"System, send me to the second floor."

The dungeon system response.

「Deducted 20 dp successfully. Begin transferring the 1st dungeon climber to the second floor.」

Arthur's body then was enveloped by blue light before his body was broken apart and floating toward the sky.

A giant door opened and engulfed his particles, officially sending him to the second floor of the dungeon.

「Congratulations for the 1st dungeon climber to successfully step inside the second floor.」

「Great Reward would be given out」

The dungeon announced it to everyone. 

It called him the 1st dungeon climber as he was the first one to step inside the dungeon.

It basically told everyone that it was him. He being the first one to step inside the dungeon wasn't a secret.

And as he expected. Everyone knew it was him and those who could go out of the dungeon would sell this news to the new reporters.

He would be famous and it would bring him fame.

However, where there was light there was also darkness.

Fortunately, those who were around him weren't normal people and they would help him when needed.

…

The second floor of the dungeon.

The World of Avatar

The Avatar: The Last Airbender world was a fantasy setting inspired primarily by East Asian cultures. 

The world was divided into four nations, each based on the four classical elements: the Water Tribes, the Earth Kingdom, the Fire Nation, and the Air Nomads.

Geography and Climate

The world was characterized by a unique geography, with all land masses clustered on one side of the planet. 

The planet's size and scale are different from Earth's, with a smaller circumference and varying climates. The world's climate ranges from tropical to arctic, with distinct regions and weather patterns.

Elemental Bending

In this world, some people can manipulate the elements through a practice called "bending," inspired by Chinese martial arts. Each nation had its own specialized bending style, with the Avatar being the only one capable of bending all four elements: water, earth, fire, and air.

Nations and Cultures

Water Tribes: Influenced by Inuit and other Arctic cultures, the Water Tribes were seafaring and adapted to harsh, icy environments.

Earth Kingdom: Inspired by Chinese and Southeast Asian cultures, the Earth Kingdom was an expansive nation with a rich history and architecture.

Fire Nation: Based on Japanese and Korean cultures, the Fire Nation was a militaristic and technologically advanced nation.

Air Nomads: Influenced by Tibetan and Mongolian cultures, the Air Nomads were a peaceful and spiritual nation living in harmony with nature.

Arthur had now appeared inside the world of Avatar with Sylvie. 

It was a little more dangerous than Re:Zero world.

Arthur looked around himself and said to Sylvie.

"Now, let's check where I am."

First floor of the tower dungeon, Re:zero world.

Everyone got notification that someone had successfully gone to the second floor.

They thought about Arthur.

He was just a teenage boy who was lucky enough to be taken in by Tony Stark.

And they thought that if he could do it they could also do it as well. 

They thought that this dungeon was easy. Even such a weak looking boy could finish it.

Many people overestimated themselves and thus paid the price with their lives.

Foolish people were everywhere, even dungeon climbers weren't not spared from stupidities.

They thought that they would never die because they were stronger than ordinary people in the Re:zero world.

However, they met someone even a high level dungeon climber must be wary of.

Elsa Granhiert, the bowel killer.

Her strength increased tremendously after she almost died by the hand of Arthur.

However, even though she became a lot stronger, she was still not confident enough that she could defeat Arthur.

"All I have to do is kill them and I will become stronger. This is easy. When I am confident enough to hunt that bastard down, I will!"

Elsa smiled widely. 

She didn't know what happened to this world.

There were those that proclaimed that they had come from different worlds.

She got this information from torturing a bounty hunter that tried to hunt her down.

And he had become her prey instead.

She then found herself becoming stronger and stronger when she killed these people who called themselves dungeon climbers.

It was exhilarating when she felt she became stronger by absorbing some kind of energy that they let out after they died.

She wanted to go to their world and hunt as many of them as she could but unfortunately, she couldn't.

"*tsk* What a lame rule. Only mabeast and monsters without sentience could come and go to their world through portals."

Elsa had found a portal but if she forcefully threw herself inside. 

She would die for sure.

She looked away from the portal and thought to go and hunt down some dungeon climbers to become stronger again.

She was addicted to the feeling of becoming stronger through killing those annoying flies.

But before she could move from where she was. 

Her back was stuck with an arrow then it exploded.

Her body was blown up but she didn't die yet.

Her regeneration kicked in and she was completely healed.

"Who the fuck dare to attack me! show yourself right now!"

Elsa felt very angry but she got stuck by another arrow in the head and the arrow exploded.

Her head was completely destroyed and once again her vampiric regeneration kicked in and she completely healed.

"That's cheating!"

Cling said through the intercom from the top of the tree that was miles away from Elsa.

He could hit her with his powerbow from that faraway.

Natasha was away from him but near Elsa. 

She looked at Elsa through a stealth magic she learnt from buying a cheap grimoire on the black market.

"This one is a little stronger than we thought. Should we deal with her like we deal with Dead pool?"

Natasha said.

"Nah, she is not that tricky compared to that bastard. We can confront her directly and capture her with an iron cage."

Clint had analyzed the way Elsa fought and he was confident that only Natasha was enough to beat her down and then locked her up inside an iron cage.

Iron cage was the newest technology that Tony had invented. 

Instead of Iron man suit, it was a cage instead and it could capture those who can move at supersonic level.

Elsa might be very fast but she was far slower to those who could move at the supersonic level.

Elsa could tell that the one who came to hunt her down this time was different from the other dungeon climbers.

They were the real deal and she wanted to escape.

However, she was kicked in the face by Natasha. 

Her head became splashed watermelon from the force of her kick.

Her brain juice was everywhere. But she didn't die yet again.

Natasha's level and stats were above her and now Elsa had met her true predator.

"Where do you think you're going? Let me hunt you down for some dp. Oh, and the price on your head is also very tempting."

Natasha licked her lip seductively. 

She could not finish her first mission because she found out who picked Emilia.

She would never fight them as she didn't want to die yet. So she picked another mission with Clint.

And that to hunt down the bowel hunter.

…

Arthur flew around everywhere with Sylvie to see where he was in the world of avatar.

He wasn't afraid of anything because he was confident that his current power was enough to deal with anyone here.

He found that there were so many volcanic islands here. And only one nation came to his mind.

"I must be in the Fire Nation."

Arthur was sure of it.

When he realized where he was. A mission was issued to him by the system.

「Mission: Become the Fire Lord of the fire nation through politics and mercifulness.」

「Penalty: Killing the current fire lord and usurping his throne through force is prohibited, failing to do so meant failure of the mission.」

「Reward: 200dp, Parameters up, ???」

"200dp? and a mysterious gift. It must be one hell of a mission and I can't directly kill Ozai and proclaim myself as the fire lord. This mission is hard for me because I don't know anything about politics."

Arthur thought he would get an easy mission but to think it would be a very hard mission for him.

He didn't know a single thing about politics. 

If Tony was with him then he might be able to ask him what to do.

「Don't worry, you have us. And didn't you get something good from being the first one to enter the second floor of the dungeon?」

Great Red said to him and Arthur remembered what he got as a reward. 

It must be very useful for his mission.

「Reward: Summon card: Takenaka Hanbei(Lv.1)」

Arthur looked at the card in his hand and couldn't help but sighed. It was a really good reward.

He knew who Takenaka Hanbei was.

She was from an anime called Oda Nobuna no Yabou.

According to what he could remember from the series, Takenaka Hanbei was described as being petite and having a somewhat child-like appearance. 

She was a gifted strategist serving Yoshiharu and a former general of the Saitō clan, who defected to the Oda clan.

Hanbei's personality was characterized as being non-confrontational and preferring to avoid bloodshed whenever possible. 

She was a skilled strategist who used her abilities to defeat enemies with minimal casualties.

She would be of great asset to help him if he wanted to be the fire lord through politics and mercifulness.

The only problem was. She was too young. He couldn't bring herself to rely on such a young girl.

His pride as a dragon was hurt so much.

Sylvie licked his face to console him.

「You don't have a choice, partner. Sometimes you have to do things that you don't like.」

"I understand that Ophis. I will summon her. But I want to find a safe place for her first. At least it will give me some peace of mind. Her level is just five and she is a fourteen years old girl at that."

Arthur really didn't have a choice. The higher the floor of the dungeon. The more dp he needed to go in and out.

He needed 10dp to go to the first floor and 2dp to get out of the dungeon.

He could not go out from the second floor to his world directly.

「You can do it, partner. If you can't become a fire lord. All you have to do is annihilate some species for dp.」

Great Red was smart sometimes and the other time he was a menace.

Arthur shook his head. There were no monsters in Avatar, only dangerous animals which he thought wouldn't give him any dp or fp.

"The world of Avatar is hard to get dp and fp through hunting. There might be small missions that might not relate to hunting but to do something for the natives like working for them."

Arthur would gather more information about this world and then he would give it to Tony in case he might want to go to the second floor himself.

Arthur looked around the fire nation for a place to settle in but he couldn't find any suitable place for himself.

「If you can't find any place you like. All you have to do is make your own nest. I think that place might be good for you.」

Arthur looked at where Ophis told him. It was a high mountain that was full of greenery.

It was in contrast to the fire nation that mostly consisted of barren lands and volcanic mountains.

He could make a base of the second floor here. Even though he might not be as good as Tony, he at least could make something decent using the nanobots that Tony gave to him.

They could make a simple base using whatever there was in the surrounding area for him.

The nanobots began to extract elements from the surroundings and 3D printed the simple base for Arthur.

It might take some time but he could wait.

"Let's summon her and hope that she will not be scared and attack me with her onmyodo."

Arthur jokingly said. He believed that the system wouldn't do anything like that to him.

Hanbei must be informed about being summoned by him. She must be willing to help him with the mission.

He used the summon card and then he saw a blue fire ball coming at him and it exploded on his face directly.

Fortunately, he was a dragon and he was tolerant of fire. Otherwise, his face might already melt down.

"Please send me back to my world! My master is Yoshiharu-sama and not you!"

Hanbei said while crying. 

She said that she only had one master and it wasn't him.

Arthur had become a kidnapper and it made him flabbergasted. 

The system betrayed his trust this time.
