I have a hero simulator

As everyone in the hall looked at each other in confusion, Lord Buu began his introductions.

"This is my brother, Veldora!"

"I am Veldora, the Storm Dragon! Everyone, please feel honored to have witnessed my appearance!"

Plop, someone fell to the ground.

The fainting passed.

"Wait a minute! Lord Buu, let's talk in private!"

The Dwarf King was shocked to see a group of people fainted from fright, and his mouth opened wide.

The entire meeting fell into chaos because of the arrival of the Storm Dragon.

But the one who was even more surprised was Rimuru. He had no idea that Veldora was not only resurrected, but also had a new body. This was something that Raphael, the King of Wisdom, did not seem to tell him.

《Information. Individual Veldora is a body reshaped by the absorption of magic essence by the "Lord of Gluttony." The "Lord of Gluttony" was acquired through a trade between the "Lord of Wisdom," the Great Sage's evolutionary form, and Individual Buu during the host's evolution.》

"So, I now have two Ultimate Abilities, right?"

Rimuru suddenly realized that it was no wonder that Brother Buu could talk to his great sage.

But it's pretty good.

After all, "Lord of Gluttony" is also a very powerful ability.

But that group of humans was unlucky.

The disaster-level monster "Storm Dragon" is indeed worthy of its reputation.

They were filled with fear and stared ahead in amazement.

But then again, it's only natural that a sudden appearance of a "Catastrophe-grade" monster would cause such a huge commotion. This monster is even more terrifying than a demon king.

"Well, my brother Veldora has just been resurrected and is undergoing rehabilitation exercises, so please don't make him too tired."

Shen Yuan waved his hand, signaling the monster officers to take the human form of the Storm Dragon Veldora away.

Chapter 401: The Battle of Heaven and Demon! The King of Justice and Rimuru Who Learns the Truth!

"Hey, Buu brother, I'm fine... Wait, wait a minute!"

Veldora said that he had just appeared on the stage for less than two seconds, and he was about to be carried away.

So he released the aura of a "Catastrophe-level" monster without hesitation. The terrifying power of up to 4600 million existence value overwhelmed like a tsunami in an instant. The rich magic essence instantly made everyone except the powerful Dwarf King foam at the mouth.

"Hahahaha! See? I'm healthy!"

However, Veldora, who was laughing wildly, did not notice the sullen faces of Lord Buu and the others.

Even the new Demon Lord Rimuru widened his eyes, wondering if you were here to cause trouble.

"Veldora! You idiot! How can we proceed if you've knocked everyone in the meeting unconscious?"

"Uh......"

Veldora finally realized what was happening and scratched his head in embarrassment.

"That's fine." Shen Yuan looked at the unconscious envoys and stood up. "Then let's proceed directly to the second phase of the talks."

As soon as he finished speaking, the hall suddenly shook.

As if triggered by layers of mechanisms, the spiral staircase unfolded downwards, revealing a magnificent underground conference room.

"All demon cadres, as well as Demon Lord Rimuru, Veldora, Dwarf King Gazel, etc., can come in. The rest of you will wait outside... and take care of the unconscious messengers!"

"As ordered!"

Soon, these people came to the underground meeting room.

Waiting for Lord Buu to speak.

Even Rimuru couldn't help but become curious about what was so serious.

After taking the main seat, Shen Yuan turned the Demon King Ring and then went straight to the point: "Everyone, have you heard of the so-called [Demon War]?"

"—!"

The Storm Dragon Veldora was stunned for a moment and looked up.

The Dwarf King Gazel narrowed his eyes and tensed up in an instant.

"Let me explain. The 'Demon War' is a war between angels and demons. Every 500 years or so, millions of angels will appear to wipe out civilizations. If a civilization develops too quickly, when it reaches a certain level, angels will descend to destroy it."

At this point, Shen Yuan looked at Rimuru and said, "We, the awakened demon kings, are responsible for fighting against the angels and preventing the extinction of existing civilization."

"What!? There's such a thing? Where did those angels come from? Isn't this restricting the progress of civilization?!"

Rimuru complained, he seemed a little confused as to why Shen Yuan suddenly threw out such heavyweight news.

"By the way, Brother Veldora, do you know about this?"

“I know. But, not only me, but even my sister Velzard doesn’t know the origin of those angels!”

Storm Dragon Veldora quickly shook his head

"That's not right. Aren't angels supposed to be symbols of holiness and peace? Why would they do something like this?"

Rimuru asked hurriedly.

"Perhaps it's because the world's resources are limited, and they want to prevent over-exploitation to protect the world." The Dwarf King Gazel also seemed shocked, and he expressed his guess.

“Is that so? Even though it’s a bit extreme, it can be considered an act of protecting the world, right?” Rimuru said with understanding.

"Lord Buu, do you think so too?"

"Definitely not."

Shen Yuan is not as simple as Rimuru. He knows the reason of this matter very well because he has read the script.

"What I'm about to tell you is something the Seven-Star Demon King, no, the current Eight-Star Demon King, has been investigating for thousands of years and still hasn't figured out. You will be the only monsters, demon kings, and demihumans in this world who know the truth."

Shen Yuan didn't seem to want to waste time, but pointed out the culprit directly.

Everyone who heard his words pricked up their ears and listened with saliva swallowing.

"The origin of that group of angels stems from the ultimate ability of 'Lord of Justice (Michael)', the skill 'Angel Army'. They are summoned instantly by the Angel Army, numbering up to a million, with the lowest level being B-rank monsters."

This sentence instantly silenced everyone in the conference room.

"Ultimate Ability...Lord of Justice!?"

"So strong!"

"But who is the current owner of this 'King of Justice (Michael)'?!"

Rimuru asked immediately.

"The current Emperor of the Eastern Empire, the first Hero, the apprentice of the Star Dragon King, the brother of the Star Dragon King's wife, a hero who has been in love and hatred with the Dark Emperor, Demon King Guy, for ten thousand years, shouldering all suffering and the goal of realizing an ideal world, the great uncle of the tyrannical Dragon Demon, the oldest Demon King Milim, who murdered his sister and brother-in-law during the ancient war when a hostile nation invaded his country, his faith completely collapsed and he turned evil, his heart corroded and he gradually lost his qualification as a Hero... His buffs are stacked up... Pain, terribly pained. The current Emperor of the Eastern Empire [Rudra]."

"Ah this!"

Rimuru was stunned, and the others looked like their brains had crashed.

Understand the applause.

But apart from Rimuru, the reincarnated being, the only ones who could understand and react were the Storm Dragon Veldora and the Great Demon of the Original Black, Diablo.

“It’s just as I guessed.” Diablo’s face suddenly became enlightened. He knew about Rudra and Guy’s affairs.

But he didn't know that the angel was actually summoned by Rudra, whose heart was corrupted.

Veldora, the Storm Dragon, was somewhat aware of the situation as the youngest brother of the Star Dragon King, but he had no idea that Rudra had turned evil and even became the wielder of the "Lord of Justice (Michael)".

"Sounds like a truly miserable emperor... a classic villain setting, and he practically nails it all!"

As a modern person who has read many light novels and comics, Rimuru has no doubt about the truth of what Shen Yuan said.

But he was very curious about how Shen Yuan knew about this.

"Brother Buu, how do you know that Rudra is the instigator of the Heaven Demon War?"

Veldora asked.

"What if I say I'm from a world higher in dimension than yours? In my world, there's a light novel and manga called 'That Time I Got Reincarnated as a Slime' that tells the complete story, and it's all finished."

“…Huh?” The most shocked person was Rimuru himself. He was completely dumbfounded.

"impossible!"

Rimuru immediately stood up and shouted, "I won't believe it unless you show it to me!"

——Oh no, I’ve become the protagonist now.

—I'm actually a character in a light novel? You must be kidding. Shouldn't I be a normal person?

——But, don't other worlds exist only in novels? Is what Buu-sama said true? Am I really just a character in a novel?

"promise."

Shen Yuan opened the summoning space, took out a few comic books of "That Time I Got Reincarnated as a Slime" and threw them on the table.

In an instant, Rimuru and Veldora grabbed a portion of the book and began to flip through it hurriedly. Demon steward Diablo, Shuna Benimaru and other demon cadres also gathered around to watch everything that happened in the comics.

"This, this is impossible! I didn't expect it to be true!"

Rimuru was shocked, and so was the Storm Dragon Veldora.

"But why is the plot different from the comic book?" Rimuru suddenly discovered a problem: "Brother Buu doesn't appear in the book."

"Of course not, because the world I live in is a parallel world line. Do you understand what I mean?"

"I...seem to understand."

Rimuru nodded, and as his brain endlessly rebooted, he gradually came to a realization: "The comic book is just one world line, and what's happening now is just like the stories in other world lines like light novels and manga fan fiction. Although they are not part of the canon, they are all real stories that exist in the two-dimensional world."

At this point, Rimuru suddenly took the initiative and asked, "So, Buu, aren't you also a character in the story?"

"Impossible!" Shen Yuan shook his head decisively. "Absolutely impossible! How could I be a character in a novel? Don't believe in rumors or spread them. I just have the ability to travel infinitely."

As soon as he finished speaking, Veldora shouted.

"Wait, why doesn't the story have an ending... Why can't I see the rest of the story?"

"I do not know either."

Shen Yuan spread his hands and said, "When I traveled through time, this novel was not yet finished. It only covered the period of the great war with the Eastern Empire. As for what happened after that, I will have to wait and deduce it slowly."

"I don't think it makes much sense." Rimuru shook his head and continued, "It's good that we know the plot in advance. But Brother Buu, you also said that this is a new and independent world line, so there is no need for us to follow the original plot. That might be counterproductive. Our real advantage is knowing what will happen in the future, and then using this information gap to change the bad things that are about to happen, so that the ending will develop towards a perfect and positive place, and that's it!"

"Yes, Rimuru, you see things very clearly. The ending of the story is in our own hands. In this book, we are all our own protagonists."

Shen Yuan said.

"This is why I gathered you here, and this is why I want to convince you—why we should attack the Eastern Empire. Now, if I say we're going to strike first against the Eastern Empire, will you hesitate?"

"Needless to say, if I didn't know where the plot was going, I might still think it was inappropriate. But now it seems like this is something we have to do."

"That's right! Now that we know the future, let's change the bad future! Strive for the most perfect ending!"

Even Veldora said this excitedly.

"Interesting." Diablo flipped through the comic book and placed it on the table, his eyes flickering. "The ending doesn't feel like it's unfinished, but rather like it was deliberately torn out."

“So, the Eastern Empire Emperor named Rudra will eventually be controlled by the ‘Lord of Justice’, who will then evolve into the Mind Core ‘Velda’. And its goal is to obtain the ‘Lord of Wisdom’, revive the true Lucia, and then destroy the world and rebuild it!”

"Is this the real reason for the great war between the Heavenly Demons? I think I know what to do."

"Yuuki Kagurazaka... and this evil creature, who finally turned against Velda and intended to destroy the world... The plot seems to end here, there is no further."

“I don’t know if it’s too late now.”

Rimuru suddenly said to Shen Yuan.

"what?"

"Go teach Yuuki Kagurazaka a lesson!" 177 Rimuru said angrily.

"You can give it a try."

Shen Yuan said with a smile, without stopping Rimuru from doing so.

Telling Rimuru about the comic book was a decision he made after much consideration. This way, he could save himself the trouble of talking too much and also give them the illusion that he had traveled back in time to save the world.

In this way, the traveler will not be alone.
