Rebirth of the Strongest Dungeon Master

He had expected sooner or later that a demon from Duke Barbatos's alliance would contact him, but Baron Gustav was the last on list. He thought Baron Loke would be the one to contact him.

Besides, he didn't expect that there would be a PvP request. Isaac was sure that he had joined their alliance. This was very interesting for him.

"I don't understand what all of you are planning. But, let's see it."

Before that, he saw the PvP reward offered by Baron Gustav. Each challenger was required to provide a zenny offer for the challenged party.

[Baron Gustav bids 500,000 zenny for PvP.]

[Would you accept it?]

[Yes/No]

Isaac snorted. "A decent amount, but unfortunately, I have my own agenda for the moment."

Isaac declined the PvP challenge, then he accepted Baron Gustav's request to speak. He felt de javu.

The light of the Crystal Core projected the figure of a demon with purple skin and pointed ears. His eyes looked at Isaac condescendingly. Baron Gustav still looked the same as the last time they had spoken; still haughty and arrogant.

Pippi, who was very familiar with the demon's face, quickly became angry. She would not forget the insults Baron Gustav had done to her master. The curses that were stuck in her throat would have come out, if Isaac not standing beside her.

"Lord Isaac, why did you refuse my PvP challenge? Are you scared?"

The two eyebrows above Isaac's eyes rose at those words. He wouldn't have expected Baron Gustav to say those words to him.

"Of course I refuse, Baron Gustav. We are in the same alliance. I don't understand why you sent me a PvP challenge?" Isaac spoke in a humble tone.

"Just accept it, you bastard! Is the entire Constantine Family this jerk?!"

Baron Gustav's insults were enough to make Isaac furious. His hands, which were behind his waist squeezed until the blood flowed out profusely. Pippi saw that, and she could only swallow her saliva with difficulty. She felt a strong killing aura radiate from her master.

However, Isaac didn't show it to Baron Gustav. He just smiled.

'Why does this bastard dare to act like this?'

Moreover, he smelled something was off. Baron Gustav had always been known to be haughty and arrogant. Even so, he would not dare to do what he wanted without orders, let alone against his fellow alliance members. It was very likely that someone was pressing him.

And, there was only one figure capable of suppressing Baron Gustav—Duke Barbatos.

Isaac still didn't understand. None of the demons told him anything about this. He then asked Pippi via telepathy if during the past one month any demons had tried to contact him, and the little girl replied with no.

Something really happened behind the scenes. Isaac shouldn't be reckless, he had to dig up information first.

"Lord Gustav, I really don't understand. Could you explain it more clearly? I'm sure there was a misunderstanding."

Baron Gustav snorted. "I don't know if you are stupid or deaf. This is my will."

"I'm not stupid. I'm trying to figure out what's going on here."

"Quickly accept my request, you bastard! I will crush you and trample your dungeon like trash."

Pippi had opened her mouth, ready to snap 1001 cursing words, but her master held the little girl back.

Meanwhile, Isaac just let out a long sigh; between disappointment and running out of patience.

He felt it was useless to dig up information by talking nicely. Demons like Baron Gustav were stubborn creatures who couldn't communicate with common sense.

'How could I ever lose to a demon like him?'

Isaac then changed the expression on his face.

"Hey, Gustav, listen to me carefully."

Baron Gustav was surprised to hear his name being called without honorifics 'Lord'. To a noble demon, this was a great humiliation, especially if it was a fellow Noble who did it.

A fierce expression appeared on his face.

"Are you—"

"Shut your mouth!"

Just as he was about to let out all the curses and insults, Isaac cut him off.

"Are you deaf?" he added. "I'm trying to be nice, but you're acting like an annoying underpaid underling."

"You bastard—"

"I haven't told you to talk!" Isaac snapped. Baron Gustav looked surprised until his eyes widened. "Remember, you are nothing. You can't order me. No matter how high your position is between them, you're just an accomplice to the Duke. Know your place."

Those words really pierced him. Baron Gustav was offended. He was really mad. The veins on his temples bulged out, even his purple-skinned face turned red, as if blood had pooled in his face. He wanted to reply to Isaac's words and let out all the curse words that stuck in his throat. However, if he got hurt, it would only make him look like an idiot.

Meanwhile, Pippi smiled so widely that her lips touched her ears. A cynical look appeared on her face. She was completely satisfied to see the Demon Lord become silent. The frustration she had been harboring for so long paid off.

Baron Gustav suddenly laughed softly. "You are right. You're right, Isaac Constantine. Now, I ask you one more time. Will you accept my challenge, or not? I hope the Constantine Boy doesn't make excuses for turning down the offer, like a coward."

HA HA HA HA!

Isaac laughed loudly. His voice echoed throughout the room. Baron Gustav and Pippi who watched were astonished. They wondered what the demon before them was thinking.

He laughed for a long time. Tears came out of his eyes from laughing too hard.

"You must be very desperate, Lord Gustav. That's how much you want to challenge me to a fight against me. Alright, I'll accept it."

Seeing Baron Gustav's behavior, Isaac realized that someone was suppressing the demon.

Ding!

[PvP request sent!]

[Waiting for confirmation.]

From the projection light, Baron Gustav looked surprised, then he looked at Isaac in disbelief. Yet, a smile quickly appeared on the demon's face.

"Are you sure about being the challenger? I'm currently ranked 70th. You should be aware of your position. I was kind enough to allow you to hide behind your cage."

"Ranks are just numbers. Power is measured by victory."

Baron Gustav snorted. "Alright. Don't say I didn't warn you. See you again at your grave."

The light projection disappeared.

[PvP request accepted!]

[Please wait 120 minutes for the challenged side to make preparations.]

A long sigh came out of Isaac's mouth.

'Finally, my first PvP in the second round of life.'

Pippi looked excited. She was still happy to see the Demon Lord's face crumpled in front of her master. Her excitement grew even more when she imagined Isaac destroying Baron Gustav.

"Lord, Pippi is ready to take orders."

"Tell Fedorov and Byakko to get ready. Collect 50,000 beast-type monsters, 5,000 of which have the ability to shoot out ice."

"Aye aye, Lord!"

Pippi's body then became a splinter of light and disappeared.

Isaac remained in the room. He stared intently at the Crystal Core, as if he was looking into the future. He saw his enemy begging for mercy while calling his name.
