Rebirth of the Strongest Dungeon Master

Hundreds of bird-like human monsters emerged from under the ravine. Half female body, and half bird. They flew in flocks. Their arms that looked like the wings of a bird were outstretched wide, showing their beautiful black feathers. They all had enchanting faces with eyes like eagles ready to snatch their prey.

The monster warriors looked up when they sensed the threat. The lycans howled, the werelions roared, and the trolls snorted loudly. All the monsters prepared for a battle.

So did their two war generals. Fedorov seemed to emit lightning sparks in his hands and cold air wrapped around Byakko.

Meanwhile, their commander looked the opposite.

Isaac didn't seem to show any signs of worries. His face was flat and calm, like the surface of the lake. He pulled out the Black Jade from the inventory. The green greatsword gleamed under the dungeon sunlight.

"Kyaaak!"

The harpies floating in the sky started to screech. It was their signal. They began to flap their wings fiercely, and the feathers fell off, shooting towards the army of monsters. The feathers released by the harpies were not ordinary feathers. It was as solid as metal and sharp as a knife.

Of course, Isaac didn't just stare at them.

"Monsters with thick skin and high defenses stand out of the line, withstand their attacks!"

The monsters quickly carried out their commander's order. Monsters with strong defenses switched positions to the outermost line; like rhinosaurs—rhino-like monsters with shells on their bodies—positioned themselves as shields. Meanwhile, monsters with weak defenses hid themselves. Those with small bodies; such as lycans and gnolls—hyena monsters with human-like bodies—hid under the feet of monsters with strong defenses. The ones who were huge and wielded weapons, such as werelions and lizardmen; used their weapons as shields.

Hundreds of feathers rained down on the monster troops. The sound of a metal piercing into a hard object echoed throughout the air. The rhinosaur's shells were decorated with harpy feathers, and they looked like a hedgehog. Bulvak—the hippopotamus-like monster with a huge belly—seemed to show no signs of pain, even though dozens of harpy feathers pierced their bodies until they were dripping blood, as if they were only bitten by ants.

Fedorov and Byakko could certainly look after themselves well. They looked fine.

"Everyone keep going!"

The warrior of monsters followed Isaac's orders by maintaining the formation. Most of the monsters weren't air combat types. Fighting them was futile. But, that didn't mean he wouldn't avenge the harpies.

He was still waiting for the right time.

A quarter of Isaac's monsters had reached the other side of the cliff, and the harpies were starting to stop flapping their wings.

"Bulvak! Get your mouths open!"

The hippo-like monsters opened their mouths, hundreds of insects then came out. The insects were parasites that nested in the bulvak. Its bulged stomach held millions of parasitic larvae that were ready to grow into flesh-eating insects. This was one of the hidden weapons that the monster had.

The small black insects that resembled beetles attacked the harpies. One harpy was swarmed by at least a hundred insects, their skin and wings torn off and they were eaten alive.

Harpy was one of the dangerous monsters when fighting in the air, especially if they were chased by bigger monsters. They were very good at taking down large monsters.

However, they were very weak against smaller monsters. Although part of their bodies were covered by feathers as hard as metal, the rest of their bodies were skin and flesh, like ordinary humans.

"Kaaaakk!"

The harpies screamed in pain in the air. They flew back and forth, and they started to fly around, crashing into each other. Some of them even died and fell into the ravine.

"Lord, I can finish them off quickly." Byakko suggested with a frown on her face. She seemed to hate those bird monsters.

"I also can finish off all of them. I'm pretty sure of my level now," Fedorov added.

Two of his best generals looked impatient to be included in the fight, but Isaac didn't think so.

"No, both of you still command the line of the troops. I don't want any of us to fall."

A look of disappointment crossed their faces, but they carried out the order obediently.

The order given by Isaac was the right decision. Byakko and Fedorov were fighters that had AoE abilities. They could kill thousands of enemies in a wide area. They were perfect for this scale of battle. However, with the current state of the field, they would only injure their own comrades.

Thanks to the bulvak parasite, three-quarters of the monsters managed to cross the other side of the ravine.

The harpies were completely helpless.

A long-awaited opportunity appeared. It was time for Isaac to fight back.

'Time to show off.'

Isaac then raised the Black Jade. He tightened his grip and poured a large amount of mana into the greatsword. A vortex of wind formed, circling the edge of the blade like a tornado.

"Feel this, damn birds."

Swoooooosh!

"Kwaaak!" "Kwaaak!"

"Kwaaak!" "Kwaaak!"

The screams of the harpies boomed throughout the sky, along with the sound of flesh and bone being cut. Splashes of blood began to fall like raindrops. They were crushed by the tornado, with the blades of wind swirling in its vortex like a blender. The harpies' body tore limb by limb and fell into the ravine.

The warrior of monsters watching the scene looked stunned. They knew that their master was extremely powerful, but it had never crossed their minds that Isaac could unleash such immense power, slaying hundreds of harpies with a single slash of the sword. This was really crazy.

Only Byakko was not surprised. She had already experienced Isaac's power. Moreover, she could feel a part of her soul resting on the greatsword. So, she wasn't surprised.

Most of the harpies were killed, the rest fled, while Isaac's troops managed to cross completely.

"Everyone, keep moving."

Isaac exclaimed in the front row. The monsters behind him followed suit. Their journey to kill Baron Gustav had just begun.

.

.

Bang! Bang! Bang!

"Damn it!"

Baron Gustav was consumed by anger. His face was bright red and his hands hit the Crystal Core multiple times. Kirnish could only watch his master's behavior.

"How could an army of harpy, C-class monsters be finished off so easily? Damn it! That bastard must be cheating."

"Calm down, my lord. This is just the beginning. Everything will be fine," Kirnish comforted.

The Dungeon Master turned to his assistant with a furious look on his face. His eyes bulged, as if he wanted to crush the man's head.

"Calm? Calm, you say? He took out 1000 harpy monsters in one hit! How can I calm down?! You idiot!"

Bang!

A hard fist landed on the wall. Baron Gustav was about to hit Kirnish, but the man dodged to the side. Kirnish didn't seem afraid. He calmly looked into his master's eyes.

"My lord, please cool your head. If you saw earlier, the power that Lord Isaac unleashed was extraordinary. An attack as vicious as that would definitely require a large amount of mana to be exerted. I'm sure he's exhausted right now."

Hearing that, the baron's eyes opened wide. His assistant's words sounded reasonable. Then, he started chuckling.

"That's right, Kirnish. You are right. There is no way the loser has that much power. That much power would at least need a high-class artefact. How could he have it?"

Baron Gustav laughed loudly, while Kirnish smiled.

"That's right, my lord. This is the right time to attack him with Gaviole."
