Rebirth of the Strongest Dungeon Master

"I'm sure Abigail has conveyed my message to you."

Isaac took off his mask and black robe. His appearance returned to its original state. The black flame hair disappeared, it was replaced by the bone white colour haired.

Meanwhile, Asriel was still putting on a displeased expression on his face. He told Abigail to leave the room.

After there were only the two of them, then Asriel opened the conversation.

"In all my life in the Heaven Realm, I've never met a demon, not even from the class of Duke, to talk about the position of the Knight Leader of Heaven. Suddenly, my servant came with a message from a Baron, saying that he would help me occupy the highest position in heaven? What makes you think I would be interested?"

Like demons, angels had their own position in the Heaven Realm.

If in the Nether Realm there were many rulers, then in the Heaven Realm there was only one, namely the Absolute One. This strongest entity had a Heavenly Army consisting of millions of angels.

The thirteen strongest of them were called the Knights of Heaven. Every single one of Heaven's Knights led at least one million angel warriors.

The Knights of Heaven were a terrible scourge for demons. They were on par with the reigning Dukes of the Nether Realm.

Asriel was one of them.

"Every living being has its own desires. No exception to the angels who are submissive to Absolute One. I'm sure you really want that."

Isaac replied in a relaxed tone.

Meanwhile, Asriel clicked his tongue in annoyance. His eyes, that shone with displeasure, were getting worse. He didn't like to be read, as if Isaac had seen his whole mind. He had never been treated like this before.

Then, he approached Isaac. There was no trace of an angel's friendly face at all, only a flat expression and an intimidating look.

"Don't mess with me, Demon."

Isaac showed a friendly smile. "Calm down, Asriel. I'm here to help you. I'll make you the Knight Leader of Heaven, replacing Gabriel."

Like Gavin Bael, Gabriel was an angel who had the strongest resources among the Knights of Heaven.

"What can Baron-class Demon Lords do?"

A threatening aura emitted from Asriel. Isaac felt a tremendous amount of pressure, just like when he faced the Duke. He controlled his breath, trying to stay calm.

There should be no violence in Eden Palace. Asriel wouldn't risk his position by attacking Isaac.

"You question my capabilities, but you're still here. Wouldn't you rather ignore my message?"

"Because you jeopardized my position! Saying that you will help me to take the place of the Knight Leader of Heaven is like rebellion! Do you think it's a joke!?"

The smile on Isaac's face vanished. He looked into Asriel's eyes with a serious expression.

"I'm always serious about what I say. You will not fall, you will be at the top. Now, did you want to hear my offer or not?"

Instantly, the tension disappeared from Asriel. The two of them didn't say a word, just stared at each other, as if trying to read each other's minds.

"First, I want to hear how you helped me."

Isaac smiled.

'Oh, Ariel. You're still as desperate as ever.'

In his previous life, in the fourth year of the game, the host of the auction was replaced by Lauriel, one of the Knights of Heaven.

According to the rumours that Isaac heard, it turned out that Asriel had cheated during the auction. He sold the auction products to the demons before the auction started. He charged a price five times higher than the opening price.

His goal was to get more zenny.

In the Heaven Realm, zenny did not act as a currency, but as a measure of contribution to the Eden Palace. The more zenny they had, it meant the better their performance was.

The amount of zenny affected their ranking. From one to thirteen, Asriel was second. Right under Gabriel.

Their zenny difference was quite thin. That was why he risked himself by cheating in the auction.

Isaac then began to explain his plan to Asriel. The angel listened carefully to every word uttered by him.

He seemed to be frowning for a long time.

"This method requires a large amount of money. Are you sure you can rival the Dukes in producing zenny?"

An arrogant smile appeared on Isaac's face. "I bought two S-class products. The dukes didn't."

Asriel was silent again, then he nodded.

"Okay. Then, what do you want in return?"

Isaac smiled so widely that his lips almost touched his ear

"I just want two things. First, you have to give me a list of products to be auctioned off. Including the details of the product."

Asriel nodded. "That is easy. Then, what's the second?"

"I want a Soul Taker skill scroll."

After hearing that, Asriel's eyes opened wide. He couldn't believe what he had just heard.

"You forgot your place, demon. It wasn't an arbitrary skill that could be simply handed over. Besides, the skill can only be owned by the angel of death," Asriel replied while shaking his head in refusal.

"I'm not saying you have to give it up for free. I'll pay for it."

One of Asriel's eyebrows arched. It was easy enough for him to understand Isaac's intentions.

"How much do you offer?"

"300,000."

"400,000," Asriel replied.

"350,000."

Asriel was silent for a moment. "Deal. But remember, you shouldn't use this skill haphazardly."

Then, the two shook hands. They both got what they wanted.

"All of your things will arrive in the dungeon."

Asriel called Abigail, telling her to accompany Isaac back to the banquet hall.

.

.

.

The banquet hall looked desolated, there were no demons showing the bridge of their nose. There were only golden portals and dishes on the table. They had returned to their dungeons.

Isaac walked hand in hand with Abigail.

'Has she gone too?'

From behind, a voice called out to him. He turned and saw four demons. One demon resembled a male human form, the other was a goat-headed demon, and finally it was a graceful woman with hair as red as blood.

They walked over to Isaac.

"You're the black flame-haired demon earlier, right? You take quite a long time."

Alyna seemed to have run out of patience. Her eyes fell on Abigail, then she snorted.

Isaac understood the situation, he allowed Abigail to leave.

"You have bad taste as a Demon Lord," the goat-headed demon quipped.

"You're telling us to wait here long so you can make love to that disgusting creature?" The male demon seemed to have an expression of disgust at Isaac. "Lady Alyna, should we include this Baron?"

Alyna was silent, ignoring the words of her subordinates. She folded her arms while looking at Isaac from head to toe.

"Baron Isaac Constantine. 99th out of 108. I've heard rumors of a stupid Dungeon Master who almost lost his dungeon. And apparently… he managed to buy a Spiritual Beast and a legendary armor set. Even knowing my identity easily. You really are a great surprise."

"Thank you, Lady Alyna," Isaac replied with a genuine smile.

Meanwhile, the two demons behind Alyna looked surprised to hear their master praising Isaac. Even them, who were in the Earl-class didn't get it.

"But that's not enough to prove yourself."

The two demons behind Alyna smirked at their master's statement.

While Isaac only arched his eyebrows. He didn't think this would happen. After impressing her, he thought the rest would go smoothly.

If Isaac would only become the duke's subordinate, just like the other demons, he might have been unconditionally accepted by the alliance created by Alyna. However, he asked for more than that.

'It's not easy to get a position equal to a Duke in the alliance. But if it was this easy, it wouldn't be fun either.'

A grin appeared on his face.

"Am I still lacking?" Isaac asked.

"You're really good at managing the dungeon and have a lot of confidence, I'll admit it. However, this game isn't just about getting a lot of points, but a life-and-death battle. I need a partner who is really capable of managing troops."

Isaac laughed inwardly. He wanted to show his memories of the past.

Alyna continued her words. "For now, we're in an alliance. But if by the next year's auction you haven't hit rank 50, our alliance is over. This isn't an order, it's a demand."

The Demon Lords could rank up by defeating other higher ranked Demon Lords. Isaac had conquered many dungeons in his previous life.

This was not a difficult thing for Isaac.

"Alright, I accept this demand. I hope you keep your word."

Alyna smiled with satisfaction. She extended her hand and Isaac took it.

An alliance had just been formed!

Just as they were done with their business, unbeknownst to them, a pair of eyes were watching secretly.
