When Marshall woke up as a Dungeon Heart he couldnt think of anything before a blue screen that Marshall recognized from novels in his vision.

  " Then uuummmm why did I reincarnate? "

  " Then why am I a dungeon and what is a dungeon? "

  " Then can you explain Mana? "

  " Thanks. Then can you describe my new world to me? "

  When he heard this Marshall started thinking about all of the of the novels hed ever read. It seems that novels got most things right when it came to the world of Trent, Mana, monsters, dungeons, Gods, and many other things.

  " Can you explain your job to me? After that you can leave. "

  " Alright thanks for the help Mr. System Administrator. Have fun with your job. "

  After that Marshall decided to try and check out his status.

  When Marshall finished examining his status he decided to get busy with creating his dungeon.

  Stolen content alert: this content belongs on Royal Road. Report any occurrences.

  Marshall had read hundreds of web novels that feature a magical world that have dungeons and he has read dozens where the main character is a dungeon. This meant that Marshall had a pretty good idea of what he wants to do to protect himself. He had even came up with a general idea of what kind of room he would create for himself should he ever end up as a dungeon. Of course Marshall never expected that he would actually reincarnate let alone with his memories let alone as something magical and non-human.

  The area surrounding Marshall was a small room surrounding his near transluscent diamond Dungeon Heart. His Dungeon Heart had an od appearence, it was diamond shaped but it had designs enlayed onto its body. The designs were a flame, wind, water, a rock, an eyeball, hands holding a heart, many symbols related to creation, and a cube with the symbols related to creation inside of it.

  The room surrounding Marshall was a simple basic room made completely of dirt. When Marshall was observing he felt something that if he had to describe it to a human was like drinking hot sauced that had been nuked in a microwave. Marshall instinctively knew that that feeling was the first strand of Mana entering and going through his Dungeon Heart. He also felt that if he wanted he could send this strand of Mana to the land surrounding his body in order to claim ownership of it. And thats exactly what he did.

  The Mana that exited his body was translucent but Marshall could feel where it was in the air. After exiting his body the Mana dispersed into the atmosphere like a fart. The Mana entered the land and only seconds after that Marshall got another screen in front of his eyes.

  Marshall naturally thought yes.

  When he claimed the land Marshall knew he now manipulate the area he claimed. He could manipulate it to create rooms, tunnels, or even statues. He could do whatever he wanted as long as he had enough Mana.

  After that Marshall waited for his Mana to be regained using the ambient Mana surrounding him. It only took mere seconds to gain the one strand.

  After claiming the first room Marshall one year claiming and regenerating his Mana. The only reason he even knew how long was because of the system administrator who would answer any of his questions. He learned that each time he would regenerate his Mana he would gain a little more than he previously used. That was the reason he spent everyday of a year claiming land and then regenerating his Mana. Despite doing the same thing over and over and over for a year Marshall didnt go insane not because he had a powerful unbending will but becuase he as a dungeon was basically immortal as long as he was wasnt destroyed. Thanks to that his sense of time was extremely skewed compared to his time as a human.

  By the end of the year Marshall had claimed 150 miles worth of land. He was very satisfied with his expanse of land. Marshall hadnt just claimed land though he had also made a series of tunnels that were about one mile by one mile in size. The maze was for him to play around with his dungeon abilities and skills. Marshall had created a story using pictures that he had engraved on the wall. The story was of a man reincarnated into a monkey dragon in a massive world ruled by Gods. By the end of the year Marshall had learned some new things about dungeons. Like the fact that in order to use the dungeon store you had to have a certain amount of Dungeon Points. Dungeon points are gained by beings invading dungeons. As long as anything that isnt recognized by dungeon as friendly is inside of the land is counted as invading.

  Marshall had also used any bugs or critters that had wandered into his maze to practice Biological Manipulation. He had created three beings that could live a life that wasnt full of suffering and agony. Honestly Marshall felt truly sorry for the amount of living beings he had ruined trying to practice.

  The three creatures he created were a lizard, a lady bug, and a beetle.

  Marshall had always liked the thought of a massive beetle pet that had an extremely strong carapace and could over power anything. So thats the first thing he did. The beetle was six legged and stood an intimidating three feet tall. The body length of the beetle was five feet long and was a nice one meter wide. The beetle was given smooth muscles that could be worked out. That was what the beetle would spend its day doing. It would workout its bosy to provide most use to its master in future fights. The beetle also had a horn on its face that could be used to scoop and hammer.

  The lizard was modified to be similar to crocidiles. Marshall gave the lizard a long elongated snout lined with hundreds of tiny razor like teeth. It was around one feet long with a two feet long tail. It stood at a solid two feet tall with mammal like legs optimized for running on flat land. Marshall gave the lizard a bludgeon on the end of its tail with spikes coming out of it. The lizard could also work out but only its legs and tail.

  If the beetle was the damage dealer of the trio and the lizard was the speedy damage dealer then the lady bug was the defender. Though it could also attack. The lady bug was an extremely strong carapace, two pairs of stiff powerful wings capable of flight, and six legs with immense stamina.

  All three of these creatures were Marshalls pride and joy and he would send thoughts into their heads on how to advance themselves in body and mind. When the three were first created they could barely follow instructions but as of the end of the year they could ace tests for middle schoolers. Which might not be extremely impressive but that was the result of Marshalls constant tinkering and manipulation of their minds.

  When he finall claimed the last mile of land Marshall was finally determined to create and open his dungeon to the world.
