Rebirth of the Strongest Dungeon Master

Overcast sky spilled drops of water. Two strongholds of the monster troops were seen marching and opposing each other on the barren land. The killing aura radiated strongly despite the rain pouring down on them. Fangs exposed, weapons drawn; they were impatient to finish off their opponents.

In a moment, the battle between Baron Gustav and Isaac's troops would begin.

The 4th floor was an apocalyptic terrain. The barren land and acid rain kept pouring down non-stop. This place should still be under construction. There weren't that many monsters occupying this floor yet. Baron Gustav was quite relaxed about building the 4th Floor, as no humans had yet broken through to the 2nd Floor. So he thought that he would have plenty of time to develop it, but who would have thought his decision had led him into this dire situation?

It never crossed his mind that Isaac would make it through his dungeon to this extent.

Baron Gustav, with blood red armor covering his body, advanced to the center of the field, approaching Isaac who had been waiting for a long time.

"To think that we would meet like this, you really are a surprise, Lord Isaac," said Baron Gustav.

Although his voice was interrupted by the sound of the rain, Isaac was still able to hear it clearly.

"I also didn't think that it would be this easy to break through your dungeon."

Baron Gustav snorted. "You turned arrogant just because you caught me off guard."

"Well, it's your fault, not mine." Isaac smirked, his eyes flashing ridicule.

Of course Baron Gustav who heard that was not happy. The expression on his face that was hidden under the helmet turned sour. He accessed the inventory. Then, a sword shot out of the thin air. He swung his weapon, then the sword lengthened and twisted like a whip.

"How strong will you be against the Snake Blade?"

On the other hand, Isaac also didn't want to lose. He took out a dark green greatsword with black gradations on the hilt.

"We'll see," Isaac replied.

The two began to glare at each other, their eyes looking into one another. Not long after, the sound of metal clashing echoed amidst the gurgling rain.

Clank!

The sign that the battle had begun.

The monster troops from both sides clashed. They charged forward while roaring excitedly, the sound of their footsteps causing a great vibration. Within minutes, bloodshed was inevitable.

"Kwark!"

Splat! Splat! Splat!

They killed each other. The four-legged monsters jumped bravely, ripping apart the opponent's flesh with their fangs, and tearing their foes to shreds. Without hesitation, Bulvak devoured the heads of the lycan and chewed their skulls like candy. Chupacabra gang up on the drakes at once.

Giant monsters went on rampage, ravaging the battlefield; The five meters tall troll swept over and kicked the monster under its feet like brushing off insects. The golems jumped here and there, stomping thousands of monsters into minced meat and crushed bones.

The monsters who could spit out fire burned the battlefield and scorched thousands of monsters into lifeless lumps of flesh. Ice thorns shot out sharply from the air, bombarding thousands of monsters.

The battlefield had completely turned into a killing field. The bodies of the monsters were strewn with mud. Blood colored the puddles of murky raindrops. A fishy and charred smell of flesh wafted through the air along with the cold rain.

There was only chaos and madness on the battlefield.

On the other hand, their commander seemed to be fighting fiercely too.

"That's all you can do, Constantine? Bring out your power!?"

Clank! Clank! Clank!

Barons Gustav's sword slashed through the air and struck Isaac several times, while his opponent continued to deflect the attacks with his greatsword. He let out slashes of wind several times that were capable of cutting the monster in half, but Baron Gustav managed to dodge it.

Coupled with his skill, 'Levitation (B)', it allowed his body to fly in the air and kept his distance away from the opponent.

Over the past two days, Baron Gustav had not only sent monsters through the Crystal Core Room. He continued to observe Isaac's fighting style; how the demon could release the wind element slash and a large tornado that was able to sweep the battlefield at once.

Baron Gustav learned everything.

Whenever Isaac made a move or launched an attack, the Baron immediately cancelled the attack with his Snake Blade. The weapon he used was a counter to Black Jade. Greatsword prioritized brute strength, so the weight of the greatsword was very heavy and required great strength to swing.

With the Snake Blade, Baron Gustav was able to anticipate the incoming attack.

"Hahaha! Come on, attack me, Boy!!! Show me your strength!"

Baron Gustav laughed as he launched an attack, his sword striking Isaac many times. Thanks to that Isaac couldn't shorten the distance between them.

Splat! Splat! Splat!

Baron Gustav's slash didn't hit the target. It eradicated the monsters around Isaac. They turned into lumps of flesh.

He was truly confident in this battle. He had already calculated the opponent's individual abilities and the strength of the monster's troops. He was sure he could win this battle.

In addition, he also bought the King Drake.

"Come on, Lord Isaac. Why are you so weak? Where is your prowess that you showed two days ago? Don't tell me you wait for the help of your two men? Look at them!"

On the other side of the battlefield, there was a drake that had an unnatural size compared to normal drakes. The creature had a body the size of an elephant and around its body emitted fire; even the rainwater evaporated when it hit the monster's body.

Drake King seemed to dominate the battlefield. It spouted fire and burned the surrounding monsters. Isaac's two main generals, Fedorov and Byakko, seemed to be having a hard time.

The monster was impervious to lightning and its scales were hard and couldn't be cut by wind blades.

"HAHAHA!"

Baron Gustav continued to attack Isaac fiercely, his sword lashing out like a ferocious snake. Blood started to trickle down through Isaac's clothes. The wounds gaped from the surface of the demon's skin.

He could make Isaac beg for mercy and kill him in this battle.

At least that was what Baron Gustav thought.

Baron Gustav grew more confident. Seeing Isaac who was getting more and more cornered, made him fight more aggressively.

Clank! Clank! Clank!

The sound of metal clashing continued to echo every time the Snake Blade was swung. Then, the crashing sound disappeared.

Shreen!

"Keugh—What!?"

Baron Gustav opened his eyes wide. The look of surprise would have been obvious had the helmet not covered his face. The Snake Blade, which became his mainstay weapon, was caught by Isaac with his bare hands.

"Waak...!"

Bam!

Baron Gustav who was floating in the air was pulled hard, falling to the ground. His body was plunged into the mud.

He quickly got up and tried to pull his sword out, but it didn't move an inch. Isaac's hand should have been cut in half. He was currently at level 80. Among the Baron class, his level was already high.

On the other hand, Isaac was smirking.

"Fuck! What item did you use, huh!?"

Instead of answering, Isaac just chuckled. Of course, that angered Baron Gustav.

"What are you laughing at, you bastard?!"

Isaac stopped laughing. "I saw a clown. An angry clown."

Those words made Baron Gustav get furious.

"Don't play with me….. Hya!!!"

Baron Gustav activated his skill. Various objects around him floated, and thousands of monsters flew through the air. He tried to fly Isaac into the sky and dropped him.

However, the opposite happened.

"Keeuuuul!"

Baron Gustav was drawn towards Isaac, as if a great force was pulling his body. His neck gripped, he couldn't breathe. His helmet was removed. An expression of surprise was clearly etched on his face.

Meanwhile, Isaac smiled in satisfaction.

"Baron Gustav, why do you look so surprised?"

Baron Gustav tried to release the stranglehold on his neck. However, Isaac's strength was far greater than he expected. He tried to scream, to call for reinforcements.

And of course, no one came.

"Don't tell me you're waiting for help, Baron Gustav. It looks like no one will help you, including your proud Drake King."

Baron Gustav rolled his eyes, then the two of them opened wide. The Drake King, the monster he got after spending 500,000 zenny looked helpless. The giant monster seemed to be a plaything of two human-like monsters, especially the monster that resembled a white-haired and crescent-eyed woman. The woman slashed Drake King's neck with her teeths.

His mouth trembled at the sight. He also felt dizzy because the air had stopped flowing into his head.

Meanwhile, Isaac seemed to smile broadly.

Suddenly, Baron Gustav's instincts screamed as if a stronger predator were in front of him. Just like the time he was facing Duke Barbatos.

His face began to turn pale, and fear crept through his body.

"Now, it's my turn."

"N… no!"

Baron Gustav's pupils opened wide. He screamed until his whole soul burst out of his throat.

Splat! Splat!

Then, the sound of blood spurting was heard amidst the gurgling rain.
