A crossover anime, where people are in Classroom of the Imaginary Era, and behind the scenes, the ki

After all, these invaders from another world were able to bypass the Great Tomb's defensive barrier and force their way inside using the Shadow Ninjas and the Mirror World.

Therefore, the conventional thinking of having guardians hold their floors and block attacks layer by layer loses its original purpose.

Simply perform basic maintenance on each layer to prevent the opponent from launching a surprise attack using reverse thinking.

In any case, Ainz can achieve instant teleportation to a fixed point without ignoring obstacles within the Great Tomb of Nazarick.

Rather than spreading out our forces and letting them be defeated one by one, it's better to gather our strongest forces together and maximize the distribution of power.

However, before the guardians could fully confirm their return...

Nazarick, representing the highest level of alert, suddenly popped up a red warning window in front of Ainz!

[! Intense spatial fluctuations detected within the Treasure Palace domain of the Great Tomb of Nazarick!]

[! Blocking magic has failed!]

[! Spatial barrier has failed!]

"what?!"

Ainz gripped the Staff of Ainz Ooal Gown tightly in his hand.

'As expected, they were using a feint; their real intention was to attack our treasure vault directly!'

'But... how is that possible? The Treasure Hall's defenses are in a separate dimension, yet they managed to forcibly break through even the Great Tomb's own dimensional blockade?!'

Ainz was terrified, but outwardly he maintained the dignity of an unparalleled supreme being.

We can't wait any longer.

'The Treasure Hall's defenses have been breached; Pandora Actor alone could not possibly handle this level of intrusion!'

He made a decisive decision:

"Demiurge, you stay here and oversee the overall situation! The rest of you guardians, immediately follow me to the Treasure Hall to meet the enemy!"

"I have granted you access to the Ring of Ainz Ooal Gown. Teleport directly!"

"Yes, Lord Ainz!"

Demiurge bowed deeply in respect.

When he looked up, the throne room was empty except for him.

He pushed up his reflective glasses and raised his hand to open the interface displaying all the information he could currently observe.

In addition to instructing the demon generals to continuously whittle down Nagumo Ya's robots outside,

His focus remained primarily on coordinating the intelligence network within the Great Tomb, attempting to prevent any unforeseen events from occurring.

Demiurge still doesn't understand how the enemy managed to break through the Great Tomb's spatial barrier and how they used world-class isolation detection devices to conduct precise intelligence gathering on them.

But in his eyes, there was nothing in this world that could withstand the divine might of the supreme being.

As long as Lord Ainz takes action personally, everything will be alright.

......

Meanwhile, inside the treasure hall.

When she heard the alarm sound, Pandora Actor did not panic. Instead, she exaggeratedly rubbed her hands together, striking an expectant pose.

As a guardian NPC created by Ainz Ooal Gown, he also serves as the guardian of the Great Tomb of Nazarick's treasure.

Logically speaking, even when Nazarick faced a life-or-death situation, he would not have had the opportunity to go out and fight to contribute.

After all, the treasures of the Great Tomb, and even the shrine containing world-class artifacts, are of utmost importance and cannot be lost.

He never imagined that he would actually have a day when he would face real combat!

Moreover, the entire treasure vault is independent of the regular floors of the Great Tomb.

It belongs to a separate alternate dimension, invisible to humans, and can only be entered via teleportation using the "Ring of Ainz Ooal Gown".

It also has the defensively specialized world-class item, the Throne of Kings, as its final safeguard.

In Pandora's eyes, this was an absolutely foolproof fortress!

Therefore, he was extremely excited at that moment.

He was already anticipating in his heart what kind of desperate yet delighted expressions would appear on the faces of those ignorant invaders when they realized that their attack had ultimately been futile, all bark and no bite!

"Come on! Let me see your cries of despair!"

Pandora whispered excitedly.

Unfortunately, he misjudged this point.

The so-called "world-class items" in Ainz's world.

Essentially, it is just a fragment of the World Tree game, imbued with its laws, which is why its power is stronger than ordinary magic.

But if you want to truly represent a world, or even confront a complete set of world laws... then you're far from it.

Examples include the Shadow Kingdom corresponding to the Ghost Mask, the Mirror World corresponding to the Blank Card Box, and even the Elf Neighborhood corresponding to the Spirit Crystal.

These are essentially separate, additional worlds.
