Rebirth of the Strongest Dungeon Master

After visiting the blacksmith's forge, Isaac noticed that human level development had increased significantly. On average, they were at level 25 to 35.

Besides, the humans were concentrated on the 3rd Floor. The hunters became more daring to explore the dungeon, showing that they had grown stronger. Even Asterious was starting to have a hard time dealing with humans compared to three months ago.

This level of growth couldn't be separated from the role of Dwarf-made potions and weapons that speed up the process of increasing their level.

Of course, it had a bad impact on the dungeon. The humans were getting closer to the Crystal Core. Luckily, he had Byakko who was the last strongest defense in the dungeon.

On the bright side, the gain of zenny Isaac had gotten, tended to increase. Most hunters died due to the debuff effect of the treasure trap rooms scattered in the Labyrinth.

Even so, Isaac couldn't sit still.

'I need to upgrade the 4th Floor.'

After returning from the auction, Isaac had 350,000 zenny left. There were still 650,000 less to add to the number of floors in the dungeon.

"Lord! Pippi bring them here!!"

Isaac snapped from his thoughts when Pippi called out to him. He stopped staring at the Crystal Core, his attention turned to Pippi who was accompanied by Asterius and Byakko.

"Good, Pippi."

The reason Isaac gathered them was to prepare to invade the humans. In other words, the Dungeon Break.

After the past six months, the dungeon had a significant increase in visitors. To keep up with their strength, Isaac increased the population of the monsters. For example, like when he asked the Goblin Shaman to cast a fertility spell on the female goblin.

The population soared. Even before the auction started, the number of monsters in the dungeon reached 310,000; while his current dungeon capacity was only 300,000.

If the population exceeds capacity, the system would automatically throw the monsters out of the dungeon.

Thus, Isaac wanted to do a Dungeon Break to reduce the population of the monsters. He had to collect as much zenny as possible in less than a year.

Of course, Isaac's decision would affect the dungeon's 'friendly' reputation.

Actually, Isaac could sell his monsters, but getting half the original price wasn't a good choice. He needed to update with more powerful monsters, considering the humans were starting to pose a threat.

'I have to earn more than 5 million zenny for next year. Or my agreement with Asriel will be ruined.'

Invading human settlements was his best option right now.

Isaac observed his two trusted generals. Then, his eyes fell on Byakko.

"If you were given 5000 troops, would you dare to lead it?"

Byakko narrowed her eyes. There was doubt on her face. "I'm sorry, my lord. To be honest, I have never led an army in my life. Since I was created, I can take care of myself. I don't need troops. No one has ever been able to match me other than my lord and Uriel."

Isaac nodded. He already knew that Spiritual Beasts were individual beings. They had no experience in socializing, let alone leading the troops. But still, Isaac had to offer to give Byakko a chance. Then, his attention turned to Asterius.

"How about you?"

Asterius seemed to think for a moment. "I'm pretty confident, my Lord."

'As expected.'

Isaac sighed.

"Pippi, gather the troop of 30,000 monsters. 10,000 troops consisting of low-class monsters on Floor 1. Then, the 5,000 middle-class beasts and the rest are up to you. Gather them all on the 2nd Floor. Make sure no humans are seen at the gathering location."

"Okay, Lord!" Pippi replied. She quickly turned into light and then disappeared.

Byakko and Asterius remained. Isaac walked over to them. He handed Asterius a box of mid-grade potions. The minotaur was surprised to receive it.

"80 middle grade potions. This is your supplies to lead the raids into human settlements. You will lead 15000 of the best monsters in the dungeon."

Asterius' eyes opened wide when he heard that command. He quickly knelt down.

"It is an honor to have this order directly from you, my Lord. I, Asterius, swear by all the minotaurs that I will not let you down."

"Get up… and prove it."

Asterius got up. Isaac patted him on the shoulder. Instantly, the minotaur's expression looked proud.

"Go, get ready."

"Yes, my lord!"

After Asterius left the Crystal Core room, Isaac looked at Byakko.

The nervous look was painted on Byakko's face. She lost her confidence when she wasn't in her true form.

Isaac grabbed both of her shoulders, and Byakko was taken aback.

"Your task will be the most important thing. Asterius and I will be outside for a few days. The dungeon would be very vulnerable during the raid on the human settlements. I want you to protect the dungeon."

"Yes, Lord," Byakko replied, lowering her head.

Isaac then ordered Byakko to stand guard on the 3rd Floor.

'The troop preparations are complete. Now I have to prepare myself.'

Since the hunters were already getting stronger, Isaac needed to upgrade his combat gear. Using Dark Fate in the human world would be too eye-catching.

He opened a shop, then bought some new artefacts.

[You bought the artefact 'Tyrannical Long Mantle (D)']

[You bought the artefact 'Elpis Goddess Gift Necklace(C)']

[You bought the artefact 'Jekyll & Hyde (D)']

20,000 zenny had been lost for the 3 new artefacts.

<Tyrannical Long Coat>

Isaac's appearance changed. A dark blue coat enveloped his body right now. A silver necklace with a blue pendant hung around his neck. Finally, a pair of black and white deagle pistols were holstered at the waist.

'I'm ready.'

[Grassland, 2nd Floor, Isaac's Dungeon]

30,000 thousand monster warriors gathered on a vast expanse of green grass; some of them were wearing combat gear, some were wearing nothing, some were crawling on all fours. They all lined up neatly, facing their superiors.

Isaac rode on a giant white bear, with Pippi sitting beside him. Meanwhile, Asterius seemed to be standing right next to them. He was wearing new battle armor. On his shoulders hung a large axe and club.

"My soldiers, do you know why I gathered you here?"

The monsters fell silent. They knew, but they were not sure about the answer. Pippi only told them that their master asked them to gather to attack the humans.

"We gathered here to slaughter humans!"

"GRAAAAWRRRR!"

An orc roared, the other monsters followed.

Isaac raised his hand. For a moment, they were silent. He looked at his soldiers.

"We've always been patient, letting them roam around here and take what they want. However, the more we let them do anything in this dungeon, they keep taking more and more. Until they finally cross the line."

Whispers began to resound in the air. Isaac could feel their emotions starting to ignite because of his words.

"Do you remember? About five months ago, 5000 human soldiers came just to finish us off. For no reason, they came, attacked, and killed our family. Our family, our friends; they were slaughtered like cattle."

"Yeah right! They killed my wife!"

"They killed my brother!"

"Graw! Graw!"

Their emotions burned. They were hysterical; invoked anger, disgust, and hatred. What Isaac said reminded them of how human greed had taken their family's and friends' lives.

For them, it was a nightmare that would never go away.

"Thanks to your toughness, we were able to beat them back. However, instead of giving up, they got more and more crazy. Every day, the number of humans who came was increasing. They kept taking our possessions; again and again. They kept shedding blood to satisfy their greed. ."

Isaac was silent for a moment, letting his soldiers burn with anger. Then, he put an angry expression on his face.

"It is time for us to fight! It is time for us to rise! They are the ones who ask for this, not us! Let us show our strength! The power of the dungeon!"

The ground shook. The sound of the angry shouts of the monsters echoed in the air. The orcs pounded their chests. The goblins continued to pound their weapons on the ground. The gnolls kept on roaring, shouting warcry.

All the monster warriors were burning with fighting spirit. Isaac smiled contentedly at it. He managed to ignite their morale.

"Lord is great. Pippi also wants to come, too bad I can't," said Pippi.

As a being born from a Crystal Core, she was bound by the dungeon. She couldn't leave her house.

Isaac then rubbed the little girl's head.

"Take care of the dungeon while I'm away."

Pippi nodded. Then, she quickly descended from the white bear's body.

Isaac's attention returned to his soldiers.

"Everyone! Come with me! Let's show them the nightmare!"

"Yeah!"

Isaac moved, then his soldiers followed suit, carrying hatred and murderous intent.
