Destroyer: Building a Dimensional Universe from Scratch

The Great Underground Tomb of Nazarick is actually a sacred place for the undead race hidden deep underground. This magnificent fortress is like an underground city, and its scale is as large as a medium-sized city in reality. Through the tough shield, you can see various fantastic scenes inside, such as forests, wilderness, cemeteries, glaciers, etc.

In the cemetery of the 1st to 3rd floors, Shalltear was on her territory, leading her undead tribe and servants to prepare for war, thinking about how to cleverly set traps to fight the incoming invaders. Ainz-sama had told her that low-level magic and ordinary attacks were ineffective against the enemy, so Shalltear decided to use the ninth-level ultimate instant death magic without hesitation.

Just then, a violent shockwave broke the silence - a huge beam from the supergravity cannon rushed straight into the protective shield of the Great Tomb, splashing light in all directions, causing a tremor that shook the entire area.

"Well, the strength of this barrier is indeed extraordinary. It blocked the conventional attacks." Lu Chen decisively ordered: "Increase firepower!"

Then came the roar of the main gun. A huge dark red energy torrent gushed out from the front bow of the starship. In an instant, the surrounding air seemed to be heated to a blazing white heat, forming an extremely dazzling energy trail that streaked across the sky like a meteor.

The main gun's firing triggered a devastating impact. When the power of the super-gravity cannon hit the shield of the underground tomb, a huge red energy ball expanded wildly at the point of contact. Accompanied by intense light and annihilation rays, this energy spread out at the speed of light, evaporating everything around it in an instant. The land within a radius of 100 miles was razed to the ground, and the forests, hills, and the monsters galloping in them were digitized into nothingness.

The deep inside of the Great Tomb of Nazarick also felt a violent tremor, and the scene that seemed to be broken by the dome was shocking. It turned out that the sky in this underground world they had been living in was simulated by magic. However, at this moment, Lu Chen shook the foundation of this great tomb.

Shalltear looked up and saw the brilliant starry sky shattered like glass. The magic barrier supporting the Great Tomb of Nazarick collapsed under the attack of the supergravity cannon, revealing the real world outside. A huge interstellar battleship, the Ten Thousand Years of Snowstorm, and the heavily guarded aircraft carriers and battleships around it, like cold law enforcers, declared the sovereignty of this area.

"What? She's resurrected?" Mio and Eluma looked at the reborn girl below in surprise. Not long ago, she was easily defeated by the dragon lady. However, in the Overlord world, as long as there are enough resources, companions can be resurrected without losing levels and energy.

Lu Chen just smiled slightly, because in some worlds, the power system is so wonderful. Even the original elves who have the ability to do whatever they want cannot have the skills to revive others. In the world of Bone King, even a small adventurer can revive teammates with scrolls or resurrection magic.

"However, it seems that we really have to say goodbye this time." Before he finished speaking, the Ten Thousand Years Snowstorm launched another attack.

Lu Chen didn't care at all how many mechanisms the Bone King had set up in the tomb, how many undead he had summoned, what kind of powerful magic he had prepared, or how strong the strongest warrior Lubed was, or what kind of horrible magic would be triggered when the eighth-level guardian Victim died... All of this no longer posed a threat to them who owned the interstellar battleship Ten Thousand Years of Wind and Snow.

As soon as the command was issued, the Wannian Fengxue and its fleet of shipgirls immediately aimed at the target, and the second round of attacks came fiercely. Colorful super-gravity cannons fell from the sky, and hundreds of erosion warheads locked onto the target and screamed to tear the earth apart, leaving behind dozens of brightly colored death areas. The forest turned into scorched earth, the earth was torn apart, and all the undead and guard forces, including the guardians, turned into dust under the high-energy rays.

The first three levels of the Great Tomb crumbled under the repeated blows, and the ground shattered into powder, revealing a deeper secret - an underground world of lakes and glaciers guarded by Golconda and Cocytus.

“Shalltear…” She was dumbfounded. “Impossible!”

At this moment, a spaceship silently broke into the Great Tomb of Nazarick. The Insect King looked up, and just as he was confused, Ikaros spread her pink wings outside the bridge of the Ten Thousand Years Snowstorm and soared into the air. She took out the purple bow in her hand and aimed at the target.

"Master's enemies detected, executing liquidation procedures!" she shouted. "Apollon!"

The Sky Queen's ultimate weapon unleashed a devastating blow in the Great Tomb of Nazarick, instantly shattering the space of the fourth and fifth floors. Cocytus, the underground lake he guarded, and the giant war puppet were engulfed in flames.

"Sixth floor, destroyed."

As the starships and the universal angels attacked in turn, the Great Tomb of Nazarick began to collapse layer by layer from the bottom. As the core base of the entire guild, the Great Tomb had always been impregnable, but the previous invaders had never thought that they could completely destroy the Great Tomb in this way.

Between the thrones, Ainz watched as the names of the newly resurrected Guardians were marked with red crosses one by one, and the YGGDRASIL game system continued to issue warnings.

[The cemetery on the first to third floors of the Great Tomb has been destroyed! ]

[The underground lake on the fourth floor of the Great Tomb was destroyed! ]

[The eighth level of the Great Tomb has been destroyed!!!]

An unprecedented crisis was approaching. Bone King suddenly stood up from the throne, widened his eyes, and stomped on the floor hard.

"Lord Ainz... what on earth is going on?!" Albedo and the Pleiades were also in a state of confusion. Although they were NPCs in the game world and had seen many invaders, no one had ever dared to want to destroy the entire Great Tomb so recklessly.

"How could this be... Could it be that their real purpose is to destroy the entire Great Tomb?!"

An was so fast in the light that no one could react in time.

The roar was like the roar of a different dimension. A beam of light pierced through the earth, creating a huge circular crater in the ground. The surrounding terrain collapsed, and the area within hundreds of kilometers fell into a silent abyss.

“Lord Ainz—!”

Albedo and the Pleiades witnessed the sudden attack of the Ten Thousand Years Snowstorm and anxiously wanted to lend a hand, but -

The aftermath of the main gun and high-energy rays swept past, instantly shattering their bodies like glass.

In the world of YGGDRASIL, the super-level magic "Skyfall" that Bone King had cast was only comparable to the main gun of the Ten Thousand Years of Snowstorm. Not to mention those powerful skills with many restrictions - such as the inability to activate continuously, the limited number of uses per day, and the long preparation time for casting.

Each of the turrets on the Ten Thousand Years of Snowstorm had destructive power that rivaled super-level magic, and the main gun that was powerful enough to tear apart a planet was even more jaw-dropping. Under the concentrated fire of dozens of super-gravity cannons "923", even the ship girls floating in the sky could feel the spreading terrifying energy.

The Bone King's health points were instantly reduced to zero, and the artifact-level Staff of Ainz Ooal Gown in his hand turned into ashes in the high-energy torrent, and the automatic interception and automatic defense gems embedded on it were completely useless. His black robe also turned into nothing under the burning of the blazing ion beam, revealing the huge white skeleton underneath.

Before the decisive battle, the Bone King had already blessed himself with many buffs and was wearing mythical-level protective equipment. Even if he was hacked by a knife, adventurers of dozens of levels might not be able to hurt him at all. But in front of this attack that surpassed the level of super-level magic, all defenses seemed so powerless.

Bone King couldn't even determine what kind of attack the super-gravity cannon was. Even though he had increased his resistance to fire, thunder, ice, and holy attributes to the limit, he still couldn't resist it at all.

All of this stems from the power of technology, which is beyond the ability of the magic system in the world of YGGDRASIL to deal with. Fortunately, the world-class item gave him a similar "battle continuation" effect, otherwise Bone King would probably disappear without a trace in the first place.

But this only prolonged his life for a few seconds.

“Why is this happening…?”

The dying Bone King questioned the invaders from another world with his last breath, asking why the other party was targeting him. He did not hesitate to use thunder to destroy the Great Underground Tomb of Nazarick.

Lu Chen stood on top of the bridge, looking down and shaking his head slightly:

"If you were stronger than me, you would probably do the same thing after discovering my world."

"Will you treat us as lambs to be slaughtered? Use us for experiments? Or hand us over to the terror princes and torturers to extract secrets from us?"

In the process of conquering the world, Lu Chen would usually choose to accept enemies who were willing to surrender. But for the Great Tomb of Nazarick, there was never any possibility of peaceful coexistence between the two sides.

Lu Chen did not think that those undead beings, whose minds were filled with thoughts of the Supreme Being and who treated humans as worthless, could live in peace with him.

"This is a dignified exit for you."

Lu Chen waved his hand, and then, a thunderous explosion echoed in the air. With the impact of high-energy rays, Ainz and all his equipment turned into nothingness. Several world-class items released earth-shaking energy during the destruction process, forming a destructive storm that swept across the tenth floor of the Great Underground Tomb of Nazarick.

The palace, which had been half-destroyed, was completely razed to the ground by the shock wave, and the royal family's numerous defense arrays were also completely destroyed.

When the smoke and dust cleared, a huge deep pit with a diameter of several hundred meters was left on the ground. A pile of black powder was scattered in the pit. It was the wreckage left after the destruction of various props.

"Tsk tsk, it seems that the Bone King has really turned into ashes."

"He claimed to be the strongest man in the world, but he was defeated in just one round by the commander. I should have let me go down and play with him."

Gudako rubbed her hands, her tone full of regret.

Lu Chen tapped her and explained, "I didn't want to cause any trouble, so I chose the simplest and most effective way to deal with Bone King. As for a one-on-one fight, as a commander, I don't need to take risks in this situation where I have an absolute advantage."

He was not willing to use his own body to endure those strange and bizarre necromancy, even if he could resist it, there was no need to do so.

As everyone slowly descended, they continued to go deeper into the ruins between the thrones and headed towards the bottom of the Great Tomb of Nazarick. The first nine floors had already turned into ruins, and when attacking the tenth floor, in order to avoid completely destroying the treasure hall, Lu Chen did not order a complete destruction.

The throne room was razed to the ground in the previous attack, leaving only the magnificent throne inlaid with gems, still standing firmly on the ground.

"Well, this is the Bone King's throne, right? I remember it was a world-class item called 'The Throne of Kings'? Honey, do you want to take it home and use it?"

Mio and the elves gathered around, knocked on the throne, and carefully examined its texture and craftsmanship.

"This thing is a tool used to prevent the Intelligence Department from manipulating it. It is of no use to us."

After thinking for a while, Lu Chen replied that the throne of kings was mainly used to hide the player's information, including level, occupation, race, etc. To him, it was just a decoration and had no practical value.

"It would be nice to put it in the main control room of the Ten Thousand Years Snowstorm. Look, doesn't that skeleton like to sit on it?"

Hearing Gudako's suggestion, Lu Chen smiled and said, "For an empire as big as ours, we should indeed prepare a throne for the commander. But if it's made of brass, it seems a bit low-brow..."

Just as he finished speaking, Gudako was hit on the head again.

"Then gold
