Rebirth of the Strongest Dungeon Master

"Wow!" Pipi was surprised. She immediately hugged Isaac's legs. "Extraordinary!"

Pippi didn't expect the combination of low-class skills to get a D-class skill that was classified as middle-class skill.

While Isaac himself seemed to have a straight expression. As if this was how it should be.

Of course, all of this was thanks to Isaac's memories of his previous life.

Long ago, there was one Baron named Krug Dantalion. He was a big-mouthed and talkative demon.

Isaac met Dantalion once during the annual Auction. They were just chatting casually. The goal was to find allies. Throughout the chat, Dantalion bragged about his achievements.

And one of them was about the 'Seeds of Mind' skill, which helped him to level up and collect zenny faster. Only Isaac was told this secret.

Isaac couldn't help but think, the boring chatter he was forced to hear at that time turned out to be useful.

And now, Isaac had that skill.

<Seeds of Mind>

[Class : D]

[Type : Skill]

[Users can control the mind of monsters.]

[Exp or zenny bonus (10% of original amount earned) will be given to the user if every monster that has been planted by the seed kills monsters or humans.]

[Limit of seeds that can be planted : 2]

At first glance, Isaac's strength seemed ordinary and useless. The Dungeon Master could control monsters, so why would he need it?

If raising the Dungeon level by upgrading using zenny, then increasing the individual level must be by killing monsters and must be a monster outside the dungeon.

The monsters purchased from the shop had limitations. If they killed a human, the Dungeon Masters would get the zenny. Whereas if they killed a monster, they got nothing.

And 'Seeds of Mind' allows both to happen. When a monster embedded with this skill killed a monster from another Dungeon, the owner would receive individual experience.

That way, Isaac could grinding the experience individually without him having to intervene. However, that wasn't the reason Isaac chose this skill.

"There is another secret hidden from this skill when it is upgraded to C class."

After obtaining the desired skill, it was time for Isaac to build a Dungeon.

"Open the Shop."

A transparent blue screen floated in front of his face. Then, he chose the 'Buy' option and a new list line appeared.

<Buy>

[Monster]

[Monster Boss]

[Terrain]

[Item]

[Artefact]

[Skill]

Isaac was silent for a long time. His fingers played with the menu options available in the Shop. While his brain was working hard pondering what he needed to buy. With a meagre amount of zenny, he had to build a Dungeon strong enough to last for the next six months.

In creating a Dungeon, there were three main things that must have existed on each floor.

Monsters, terrain, and monster bosses.

If the Dungeon was a castle fortress, then the monsters in it were soldiers. For that, Isaac needed strong monsters. At the same time, he had to adjust the difficulty level so that there would still be humans surviving when they entered his Dungeon.

Visitor traffic affected financial and financial affected the resources.

[You bought 500x 'Blood Bat (F)']

[You bought 500x 'Slime (F)']

[You bought….]

[All monsters are added to inventory]

After purchasing the required monsters. Next, Isaac bought the terrain.

[You bought the 'Pine Forest (F)'

terrain]

[You bought the 'Grassland (F)'

terrain]

[You bought the 'Maze (E)' terrain]

[All terrain added to your inventory]

Terrains didn't just function as human barriers and demons to reach the top of the Dungeon. It also functioned as a habitation for monsters.

If the habitation of the monsters was not suitable, they would weaken. Some were not able to reproduce. Some had died.

Like Goblins who would breed quickly and fought better when living in the forest, but their physique would weaken if they lived in the mountains.

Still, it depend on the monster itself.

"Last, monster bosses," said Pippi.

Monster bosses were the strongest existences on every Dungeon floor, and there was only one. They were the last line of defense, preventing any life forms from outside from climbing to the next floor.

However, Isaac didn't buy it.

Pippi had a questioning look on her face. But after seeing the amount of zenny Isaac had, she immediately understood.

That was not the reason, though.

In total Isaac spent 44,500 zenny. Now it was time for Isaac to move on to the next stage.

"Activate the control panel."

Another transparent blue screen appeared. This time there were a lot of options listed there and a blank map. Additionally, a visual screen popped up, showing a white scene.

"Pippi, help me recreate the details of the Dungeon's first floor."

"Okay!"

Not long after, Pippi disappeared and showed up on the visual screen, in that all-white place.

Right now, Pippi was on the first floor of Dungeon.

"All right, Pippi. Let's get started!"

Isaac's hands then moved quickly and his fingers began to press the various options on the control panel screen.

Ding!

[Inputting the 'Pine Forest' terrain on the 1st floor.]

[Loading the data]

[Processing…]

[Finished.]

The visual screen that originally looked white had changed to a green landscape of pine forest. Above him was a bright blue sky with specks of white clouds. Golden rays of sunshine peeking through the clouds gave a bright colour to the place.

Pippi was bouncing up and down from the visual screen. Isaac immediately reminded Pippi to stay focused on her duty. After synchronizing with the Crystal Core, Isaac was able to communicate via telepathy with Pippi.

Then, the little girl started doing her work. In both of her hands touching the ground, suddenly a light appeared like a swarm of fireflies. Not long after, the ground turned into water. Little by little, the water expanded and created a river flow.

After that, Pippi started creating other things. Big stones, flowers, ferns, mosses, dead trees; one by one began to emerge from the light that Pippi gave off.

While Isaac still looked busy with his control panel screen.

[Inputs x500 'Slime (F)' to floor 1.]

[Inputs x500 'Blood Bat (F)' to floor 1.]

[Inputs x500 'Three horned wild boar (F)' to floor 1 .]

[Inputs x500 'Direwolf (F)' to the 1st floor.]

[Inputs x500…]

Isaac scattered various monsters onto the map. He didn't drop haphazardly. Every monster that was sent down was guaranteed to have prey and predators.

"I have to create an ecosystem with a suitable food chain. That way, the population will be controlled," Isaac muttered.

Thousands of mistakes in his previous life taught Isaac a lot of lessons.

It took 4 hours for Isaac to build the 1st floor. After that, he proceeded to the 2nd floor and 3rd floor with the same process.

The 2nd floor ran faster because the terrain was a meadow. Pippi only gave details in the form of large rocks and layers of mist. It was just that there were a lot of four-legged monsters with high defence. It only took 1 hour to complete.

Meanwhile, the 3rd floor took the longest, because the terrain on that floor was a maze. Isaac not only spread monsters but also prepared various traps. On this floor, Isaac really paid extra attention, it must be made as deadly as possible. Because this floor connected to the Crystal Core room.

Without a monster boss, his Dungeon was very breakable. However, there was no worry at all on Isaac's face.
