'An unfamiliar ceiling and the lack of chakra, I guess I have been given another chance. I can't even die in peace when that asshole is involved. I thought he despised my existence so why play with me now.' Naruto Uzumaki the former seventh Hokage of the hidden leaf thought as he opened his eyes or just woke up as he didn't have any eyes.

The final battle with the Otsutsuki king had been his demise but he was satisfied with it as he had lived long enough and all enemies had been taken care off so he could die with a light heart. Naruto looked around and could see that he was in a dark area; standing in front of him was a female skeleton that had no equipment except a rusty spear.

Naruto stood up and checked to see that he was similar as he was a skeleton with a rusty shield and a sword along with a broken chainmail.

'So he decided to make me an undead and unlike others no chakra for me. I guess I can live with that, it would have been boring otherwise. But what is up with this skeleton, I feel a connection to it and this place.' Naruto thought as he moved his body to check his strength

'Very weak, even little academy students would have better stats. Also, what is that dark energy inside of this body? Is it mana? If I am an undead, does that mean there is a necromancer around like those games?' Naruto contemplated and decided to look around but first he decided to check if he could communicate

Naruto touched the skeleton beside him and spoke, "Can you talk? Do you have a name?"

Naruto muttered but he realized that he only made some clacking noise and the skeleton just stared at him blankly.

"Ok, just follow me." Naruto muttered as he felt that the skeleton was related to him

Naruto walked in the dark corridor with some light from the torches, he came across some other skeletons but ignored them and continued his path. He walked deeper and deeper; finally he arrived at a large door and entered it.

Inside Naruto found skeletons with bows, a mace, a staff and one that looked like a knight and was larger than all of them.

'This feels like a game and that large knight should be the boss monster of the dungeon. Is this a dungeon or are my guesses wrong?'

'What should I do now?' Naruto mused as he sat down on the throne that was behind the knight while the female skeleton knight stood on his side

"I will call you Hilda as seems wrong not to have a name for my new companion." Naruto muttered as he looked at her and it seems the flames in her eyes flickered a bit

'Guess she might change with time or something.'

'Should I fight them and see my limits then leave? Can I even get a human form as I don't know how to use mana?' Naruto mused as he got up and left the room, he approached a team of 5 and attacked by surprise

He slashed at the archer from the back and kicked the warrior, the monsters recognized him as an enemy after those actions but there attacks were quite clumsy.

'This definitely feels like a game. That attack should have cracked its head but I don't see any visible damage and I can see a screen displaying their health points.'

There were more of them but they had zero skills compared to him, Naruto blocked and deflected the attacks. He maneuvered them into damaging each other and even Hilda helped by providing support even if it was minimal.

Naruto finished them off with a thrust to their skulls, using the mana within and concentrating it on the sword. The sword was covered in dark energy and broke through the skulls, dealing very high damage.

'LV 68'

'Swordsmanship: Beginner LV 3, Increases Attack Power with a sword (+30% ATK)
Increases Attack Speed with a sword (+9% ATK SPD)'

Naruto looked at Hilda found that she had LV 2 Spear Mastery at the beginner level and her level had increased by 1 so she was now 64 while he increased by 2.

'Either this world is messed up or I am inside a game.' Naruto thought as he took in what had happened till now

"Let's decide where I am, after meeting someone who can talk and give me information." Naruto muttered as he walked away from the boss room and finally he arrived at the gate leading to the outside.

'Someone is coming.' Naruto thought as heard the sounds of footsteps and hid in one of the dark corners with Hilda

Naruto watched as a party of humans walked inside the dungeon with confidence and walked the path that Naruto had taken.

'So they are here to slay the boss monster.' Naruto concluded and decided to follow them from afar as they slew the monsters and entered the boss room

Naruto waited for some time as he heard the sounds of fighting from inside and the sound of the leader, who had blue hair and seemed to have a very arrogant personality.

"I will surpass that bastard Shiro soon and show him his place in Royal road." The leader had shouted when he entered the room, the voice was filled with jealousy and hate.

'So I am inside a game called Royal Road and it seems to be the virtual reality type from what I saw of their movements.' Naruto thought as he waited patiently and finally entered the room; the party of adventurers had finished the boss and was resting a bit as they had lost a lot of health.

Naruto didn't waste time and dashed towards the leader, the sword pierced his throat with ease as he was a mage. The party was unfortunate to have met Naruto at such a weak point and was slaughtered with ease as they lacked mana and health.

'Level 70'

'Sword Mastery LV 4'

'Martial arts mastery LV 1'

The players were killed and he didn't hesitate as they were not the type he would like to interact with. Naruto saw that the bodies dropped some equipment and dropped his own equipment for the player's equipment. He got a new steel sword and a small round shield along with a bow and some arrows while he gave the iron spear to Hilda.

'This is much better; I can feel that my attacks will be better.' Naruto thought as he sat on the throne and was contemplating on what to do when he saw a message.

'Conditions Satisfied for Rank Up to higher species'

'Designated as the boss of the Undead Dungeon, please try your best to survive the onslaught of fighters.' Naruto heard inside his head and could see a light cover his body, this went on for a while and finally it stopped.

Naruto could see that he was wearing a set of silver armor and his size had changed, he was standing at 2.2 m now.

'Summon Undead LV 2: Skeleton warriors, Skeleton Mage and Skeleton Archer'

'Berserk LV1'

'Riding LV1'

'Shield Bash LV 1'

'Archery: Beginner LV 1'

Naruto could feel the increase in power and the connection with the monsters inside the room, they were his to command.

The monsters had just freshly been restored when Naruto killed them all but he realized that he got no experience from killing them and they didn't resist.

"That makes sense; it would have too easy otherwise." Naruto muttered as he walked outside the room, thankfully he wasn't stuck to the room.

With no more obstacles Naruto exited the dungeon and saw the new world, he was in a forest and the dungeon was underground as expected. The outside world was definitely much more dangerous so Naruto was careful and walked cautiously but after walking 1 km in a straight line, Naruto found a problem.

He couldn't walk further as he received a notice that he couldn't be further than 1 km from his dungeon.

'Well that sucks now what to do, there is no way I am staying here.' Naruto mused as he swung his sword around playfully

'Maybe I can increase my territory in some manner.' Naruto thought as he located a bird in the sky and shot it down.

The large eagle fell down within his zone and Naruto killed it, and used raise undead on it. The bone bird rose into the sky at his command and flew in the direction he commanded without a problem.

'So my servants can go further than me.' Naruto concluded and walked back to the dungeon, he decided to expand it as it was his only choice for now
