I have a hero simulator

On the other side, Lord Buu, whose body had transformed into a twenty-meter-tall figure, reached into the furnace-like core of his chest and pulled out a huge bloody sword. His figure gradually grew larger under the pressure of his giant wings, and gradually everything around him was shrouded in his shadow.

In a flash, Lord Buu transformed into a gigantic sword demon, looking down at Rudra and the others from above. He flapped his massive blood-red wings, his voice shaking the air as he spoke, "Ignorant creatures, I will bestow upon you the most powerful test you can't even imagine. If you still have potential and dignity, then try to defeat me!"

At this moment, Demon King Buu seemed to be able to swallow the world, which was shocking. He laughed madly, confident and arrogant.

The eyes of the World-Destroying Demon were filled with murderous intent.

The will of destruction.

They angered the real devil.

Demon King Buu gave in to his anger and activated the "King of Rage" to infinitely increase the amount of magic energy in his body, releasing the power he had been suppressing.

"[God-Slaying Sword: Ragnarok]!"

Then, the Demon King of Destruction spread his blood wings and raised the blood sword in his hand high, which instantly turned into a terrifying weapon composed of pure magic elements. The dark sword, which carried the momentum of destroying the world and had a fatal restraint on gods and angels, was swung high and fell, slashing towards the front.

"Your Majesty, get out of the way!"

Upon seeing this, the group that protects the emperor, members of the 'Emperor's Royal Guard', immediately stepped forward to protect their master.

but--

The extremely brutal giant sword had a very large range AOE. Countless angels were hit by the giant sword, their wings were broken, and their bodies made terrible cracking sounds. At the same time, the earth vibrated "190 times", and the shock wave turned the surrounding imperial capital buildings that had not yet been razed to the ground into ashes again.

"Angels, focus your fire on it!"

Suddenly, the white army appeared.

Dense heavenly armies swooped down from the sky, rushing towards the world-destroying demon like a swarm of bees. They flew into the air holding spears like Valkyries, swooping down with thunderous roars.

"This is my army of millions of celestial beings. How can a mere demon king possibly be their opponent?"

"Then you really underestimate me."

The next moment, the world-destroying demon who had raised the God-killing Sword suddenly raised one hand high, a crack appeared in the void, and then a beam of light fell on his palm.

Then the light went straight through his palm, and the powerful star beam tore through the dimension, melted the space-time, and hit his core.

As if being charged, the World-Destroying Demon, who had obtained energy from another world, turned red like molten lava, and cracks began to appear on his skin, making him look like he had entered a violent state.

After gaining energy, the Demon King of Destruction's body, the huge blood wings behind it began to wriggle, and his body began to change shape again like a slime, but this time the transformed form was no longer a human form, but a beast form!

"Activate the ultimate abilities 'Lord of Wrath' and 'Lord of Gluttony'!"

"Third Form: The Primordial Beast—Tiamat!"

Suddenly, the huge slime ball began to shoot out hundreds of millions of tiny tentacles. These tentacles carried deadly penetrating power. After hitting the army of angels, they instantly sucked away their energy and dragged them back along with their flesh.

Soon, the slime's body began to grow larger and larger, twenty meters, forty meters, one hundred meters...three hundred meters!

Under the destructive power of those endless tentacles, in this battlefield where one is against ten thousand, Shen Yuan's move combined with Rimuru's is simply unstoppable!

An army of millions of angels?

This time, it ate more than half of them. The bigger the slime was, the more tentacles it would split. If the tentacles were cut off, it would turn into little demons and launch a self-destructive attack. Under this terrifying harvest of tentacles, more and more angels disappeared with screams and turned into energy for this huge meat ball.

"Roar--!!"

Suddenly, the slime ball that had swallowed a huge number of angels began to wriggle and transformed into an evil dragon that was 6666 meters tall and as big as a mountain. It had dark scales, dark red blood flowing like magma, and huge horns pointing straight into the sky. It then let out a demonic roar that resounded throughout the world.

The most powerful and original dragon!

"Give back all the energy you stole from this world!"

"I'm going to devour you all! Eat you up completely!!"

As the demonized primordial beast Tiamat roared, it raised its huge claws and smashed them down on the ground. Endless magma rioted, and a dimensional crack appeared in the sky. The terrifying black mud from the [Imaginary Space] pressed down on this world, ruthlessly and greedily devouring everything, not letting go of a single blade of grass or tree, and even absorbing light, air, and heat!

"Oh oh oh oh!!"

At this moment, the cute king "Rimuru" who was in the body of the original beast shouted excitedly. At first, he was worried about what means Shen Yuan would use to deal with so many angels. Was he really going to self-destruct and cause large-scale casualties?

I didn't expect there was such a method.

Gain size by devouring angels and transform into the ultimate and terrifying world boss - the primordial dragon Tiamat!

This is the name of the "Dragon from Another World" that only Rimuru knows. Tiamat does not exist in this world, so when Rimuru heard Shen Yuan shout out Tiamat's name, his body trembled and he became excited.

"As expected of Big Brother Buu, I didn't expect you to be able to transform into three stages! The big demon just now was already impressive!"

In any case, Rimuru also has some control over this 6666-meter-tall behemoth, but not on its body, but on some organs that control magic. For example, the earth-shattering and lightning created by Tiamat, and the power to tear space are the magic skills added by Rimuru.

[Imaginary Space] is a super-evolved version of [Stomach] + [Isolation]. Given the size of a behemoth like Tiamat, the range of this skill is also very large. Thousands of meters of sky are cracked, and the black mud erupting from it begins to frantically devour the matter in reality.

Therefore, through Shen Yuan's power, Rimuru was able to fully experience the thrill of being the 'final boss'.

soon.

Amid the roar of the primordial beast Tiamat, it began a killing spree.

The giant dragon, the king of monsters.

In front of the huge monster like a mountain, even the Scorch Dragon, Storm Dragon, White Ice Dragon and Milim looked very petite. The tail behind the Tiamat Dragon split into thousands of parts, transforming into tentacles with dragon-like teeth and heads.

The poor angels all became victims.

Not only that, the dragon Tiamat also emits a devastating breath like a monster. The breath composed of pure magic elements it spews out divides the earth. Like a creature created by the creator god, it changes the terrain at will, creating mountains and canyons, shaking the continent!

"Your Majesty, retreat quickly!"

"We are no match for them. Monsters like that are simply not something humans can fight against!"

Gradually, fewer and fewer people remained loyal to the emperor, and they watched as the million-strong army of angels was slaughtered.

Those soldiers who were originally loyal to the emperor all began to panic.

It is because they cannot win that they choose to use verbal warfare to buy time. If it turns into actual combat, it will basically be tantamount to suicide.

To put it bluntly, there is nothing great about Emperor Rudra; he is simply pretending to be great.

But after truly angering King Buu, the world-destroying power he displayed instantly overwhelmed everything around him. People's hearts were in chaos, and the team became difficult to lead. King Buu seemed to be well aware of this, and continued to spread fear and panic, causing Emperor Rudra's subordinates to begin to fear and dread him, and thus lose confidence in victory.

In this way, Emperor Rudra would be defeated.

"I told you, I will make you feel extremely desperate!"

"Don't think I'll let you off easily. The real doomsday has just begun!"

"[Dark Star Territory——Deploy!]"

The primordial dragon Tiamat suddenly roared towards the sky, and its huge body instantly glowed and became brighter.

"what happened!?"

The dragons suddenly stopped fighting.

They looked towards the sky in horror. At this time, the dark night starry sky had been covered by a spiritual force. The stars in the sky suddenly went out collectively, as if something terrifying was about to come. The stars no longer twinkled, but were in awe and fear of something.

A dark force in the vast universe began to vibrate, and then endless stars began to be sucked uncontrollably in one direction.

In the very center of the deepest darkness, a huge vortex appeared, gradually swallowing and destroying countless stars. But just when people thought it was the end, the 'black hole' that swallowed the stars gradually revealed its true face.

That was not a black hole at all, but the eyes of "Him"!

Suddenly, the minds of all living things in the world were shaken, as if they heard some obscure voice of a god.

[I am... the uncrowned god, I am the dark snake—with a flick of my sleeve, I swallow the endless starlight!]

In an instant, the huge "eyes" that swallowed the stars gradually moved away and became smaller and smaller, but the outline of a starry sky giant appeared. As the giant raised his arms, everything above the planet began to move and time accelerated rapidly. The world jumped through countless days and nights in just a few seconds. The sun and the moon began to flicker uncontrollably and rotate rapidly.

The stars are my eyes. They will also be gradually extinguished by me.

When the figure of the star giant, the Death Star Lord "Jin" gradually faded away, the "still" world began to return to normal, and the stars that disappeared in the sky also appeared tremblingly again.

However, the timing was misplaced.

The Eastern Empire, which was originally engaged in a fierce battle, felt as if years and decades had passed. Everything was dead and dying, and then began to grow again. The once prosperous buildings were now covered with green vines and plants, and Emperor Rudra's army of millions of angels disappeared at the same time.

Many of his subordinates were also suddenly shocked to find that their strength had already aged and disappeared!

"No, it's impossible!"

Just when they saw the Star Giant (Death Star 'Zun' Jin) start to move the planet, time was accelerated, but the group's thoughts did not stop. In their perception, time only passed for a few seconds.

But in reality, I don’t know how many years have passed.

When their minds returned to normal, they were horrified to find that their bodies had already entered the aging stage, and some were even completely cold.

“Impossible, my empire...can’t be destroyed just like that—Lucia...!!”

Emperor Rudra looked at his withered arms and his aged face, his pupils dilated.

He was no longer able to stand. Before he fell, he looked forward in disbelief and called out his sister's name.

"No, it's not over yet! This damn mortal body!"

However, the Lord of Justice (Michael) seemed not satisfied with Emperor Rudra’s physical death and wanted to launch a final counterattack before his death.

Finally, someone approached him, and when he looked closely, it was none other than Kagurazaka Yuuki.

"It's you!"

Archangel Michael recognized Yuuki as the person who had betrayed him before and was forgiven.

It seems that what Zhuo Yanlong said was right. This kind of traitor will definitely find a way to retaliate against him.

"Ahahaha, finally, my chance has come!"

Just as Kagurazaka Yuuki reached out to touch Emperor Rudra's dying body, Emperor Rudra saw the shadow in the sky covering him, and immediately revealed a look of helplessness and despair, but there was also a hint of relief and gratitude in it, as if he was thanking Lord Buu for finally freeing him from the cycle of pain.

The next moment, the bloody mouth of the primordial dragon Tiamat fell, devouring Emperor Rudra's aged body and Kagurazaka Yuuki completely.

"No--!!"

Kagurazaka Yuuki looked at the bloody mouth falling on his head in horror.

But how could he possibly resist such a terrifying existence?

In less than a second, Kagurazaka Yuuki was reduced to ashes.

Disappeared with the emperor.

[System:] You devoured Emperor Rudra and Kagurazaka Yuuki, and obtained the "King of Justice" and the "King of Greed"!

Is this the result of angering the strongest demon king in another world?

Rimuru couldn't help but think in shock. At this moment, he was in Tiamat's body, looking outside through his eyes.

Like a dragon wrapped in lightning, Tiamat fell from the sky, and the thunderstorm surrounding it indiscriminately destroyed everything on the earth.

Now He is the true God.

It was as if he was the once invincible Star Dragon King. Although his power was not as great as the Star Dragon King, the methods he displayed also shocked everyone, including the dragons.

"Submit and bow down to me!"

"Dragonkins!"

Then, a mighty dragon roar was heard. After devouring the "Lord of Justice", the dragon of Tiamat gained the power to control the "Dragon Species".

In an instant, immense pressure poured down upon the Scorch Dragon, the White Ice Dragon, the Storm Dragon, and even Milim.

In addition, there is an "evil dragon" on the Empire side, who kneels down and surrenders as the fifth dragon species. This dragon is the "Earth Emperor Dragon" Velgaia in the original work. You can see it as the reincarnation of Milim's pet Gaia in 0.3.

"Lost... Damn it!"

The Scorching Dragon Velgrind bit his lip but gave up resisting.

"As expected, Buu~!"

After the White Ice Dragon Velzard regained consciousness, he immediately stopped fighting and was filled with joy.

"Wahahaha, my brother is really reliable!"

The Storm Dragon Veldora was extremely proud, and seemed to think that it was a very wise decision to say "three sworn brothers" when the cave was sealed. Now it seems that it was indeed true.

“That’s amazing!”

Milim also looked over here excitedly.

The Archangel Lucia was destroyed in the battle long ago, but was resurrected by Shen Yuan, who now controls the "Lord of Justice (Michael)". Although Michael still wants to resist, he cannot shake Shen Yuan's will.

Is Michael, just a Seraph, so arrogant?

It seems that the highest combat power in this world, apart from the bug of the Star Dragon King, is capped at the level of Seraph.

“Is that the end?”
