Just flew into the heat wave-ridden door.

The barely noticeable "flying insect" had quickly transformed into a wall-colored gecko, sticking to the soot-covered ceiling, looking down at the clanging "workshop" below.

Just one glance made Aiven's heart skip a beat.

"This is... Magnetic Ore? And... claws of the Remnant Race?"

In the most prominent position in the center of the "workshop," a translucent hexagonal crystal pillar stood, as it shone brilliantly, converting endless energy into surging thermal energy, supplying the entire production line of the workshop.

An assumption that existed for a long time had been confirmed.

With the boot hitting the ground, the technology of Magnetic Ore from the Fourth Era's Zongderilic Civilization finally appeared in the essence-controlled "Lowland Republic" and "Golden Palm Federation" by the Evil God.

If it weren't for the limitation of the unique raw material mountain copper,

It's possible that the Ancient Gods originally from the Fourth Era had already mass-produced "floating battleships" and "single-person flying devices."

Fortunately, this technology poses the same limitation on both parties.

Just like many witchcraft tools, these semi-technological creations based on extraordinary materials cannot be mass-replicated at all.

At least even Olivia, an upper-rank wizard with the True Sight Demon Eye and the Alchemy Ultimate Magic Book: Jade Record, cannot replicate the extraordinary metal mountain copper.

One must know that she has publicized to the human world the Periodic Table of Elements that reveals the essence of the world, and enjoys fame globally as a female scholar besides her title as Duchess of Galliot.

To some extent, even though she hasn't held the "breakthrough" ritual yet, she has surpassed everyone in the world in the field of material composition.

Now that Magnetic Ore has appeared in the Golden Palm, it is reasonable to infer that they might also have mastered other civilization relic technologies?

At least during the time Angie, Serra, and others explored the relics of the First Era and Second Era, the hunting team of the Evil God's side had long vanished.

Conservatively estimating, they have completed the task of collecting claws of the Remnant Race.

The advanced technologies of a few major civilizations should have somewhat fallen into the hands of these Evil Gods, even though they are by far not as professional as our own Great Wizards with their corresponding paths.

However, not all the black wizards of the "Black Pyramid" are incompetent, which indeed demands caution.

Temporarily putting this issue aside, Aiven's Eye of Profound Wisdom has now turned to the claws of the Remnant Race.

Even the claw stored in the raw material area of the workshop has piled up like a mountain, not knowing how many victims they came from.

The claws of these Era Survivors, like the "Ten Kings" blood, appeared normal in the "Time Prison" but underwent bizarre distortion, proliferation, and alienation after entering the Material World.

Some resemble sharp daggers, some transform into spiral horns, some swell into stacked terrifying bone tumors... but the commonality is they all emit a faint metallic luster.

Clang clang clang...

A group of humanoid demons with sheep horns and black scale armor are melting down, smelting, and forging those claws, ultimately processing them into sheets of black boards of uniform specifications.

The dusk-like Extraordinary Spiritual Light was intense to the point of being dazzling.

"The claws were processed into a certain raw material, and these guys are the Demon Banner of Baimon, the God of Deceit of the Supreme Four Pillars?"

Of course, Aiven had long recognized the seemingly ill-tempered "Dark Prince."

With male features, a single-humped camel, and three female heads, the traits are so vivid.

As one of the Supreme Four Pillars, this Demon God is a household name throughout the Extraordinary World; as long as one has come into contact with black witchcraft, they mostly know His summoning ritual.

He prefers robust male bodies the most.

To complete the required possession ritual, a qualified male body and three exceptionally beautiful female heads must be provided.

Legend has it that He has profound attainments in science, art, and secret techniques, being willing to grant knowledge to humans and provide excellent servant demons to pass on skills.

For instance: the composition of planets, why ships can float on water, various scientific inventions from ancient to modern times; what the Spirit is and where it resides, granting you glory and might with the power to consolidate it;

As long as the summoner wishes, they can make any mortal under their control....

This monarch ruling the West, holding the highest rank as the Dark Prince, is not only the "God of Deceit" but also the "Secret Technique Master," "Incredible Scientist," and "King of Fallen Angels."

Once an angel to some True God, eventually fell into the Lower Realm, becoming an immensely powerful Demon God!

At the same time.

Legend has it, He also has a large troupe of deaf Demon Banner, skilled in playing extraordinary instruments, being His brilliant aides in art, science, and secret technique fields.

Evidently, these are the ones appearing in front of Aiven.

At this moment, the Death Messenger and Demon God Baimon also walked into the workshop together.

Holding his breath, Aiven quietly perked up his ears.

The atmosphere of bustling work softened the tone of the "Death Messenger," who slightly bowed to the Demon God:

"Your Majesty Baimon, the 'Wealth Church' has sent news that the vehicle to carry the gods behind the door, the [Mythical Battleship: Nagilfa], is scheduled to begin construction soon.

The gods have entrusted us with the task of processing raw materials, and you wouldn't want our part to delay the schedule, would you?"

The initial processing of the raw materials obviously couldn't wait until everything was entirely collected to start uniformly.

However, the progress remained slow until the "Dark Prince," who possessed corresponding powers, joined the plan, significantly shortening the processing time.

Even so, the impatient Evil Gods were still somewhat dissatisfied with the speed.

Baimon took another swig of wine and snorted:

"Of course, I know. To the gods, only using materials built from the nails of survivors from four eras and humans of this age can enable one to re-emerge after entering 'behind the door.'

The qualification to enter 'behind the door' and providing me the 'Blood Sacrifice Divine Statue' to restore power is part of the deal, provided the [Mythical Battleship] can launch.

But I have limited Demon banners with me; to further speed up processing unless you can advance payments to me…"

"Mythical Battleship...Nagilfa? Behind the door?"

Mulling over their conversation, Aiven finally solved a long-standing mystery in his heart.

The Ancient Gods and Evil Gods collected nails also intending to go "behind the door."

But a new question surfaced in Aiven's mind; previous eras' demigods haven't mentioned needing ships to go "behind the door."

"Repeated exits from behind the door? Is the absence of all Ancient Demigods in the current era because of this?

Moreover, in the dual-track operation, what is the significance of the 'Capital Torrent'? Could it really be like 'Weakening Compensation,' simply to accumulate [World's Favor]?..."

Thinking about it was giving him a headache; as a gecko, Aiven thought about knocking his head.

Unfortunately, his arms were too short to reach.

Aiven was now somewhat eager for these guys to quickly apply his "electric pulse and signal transmission technology," even if they stole it, he wouldn't lose.

Because through that, he could directly employ the powers of the [Badge Knight] and [Eye of Profound Wisdom] to read the electromagnetic wave information flying in the sky.

Directly becoming the "Information Omniscient," finding all the answers he wanted.

Suddenly, Aiven's heart lightened with joy.

"Got it!"

The next second, his vision shifted, transitioning to another place within the Wizard Tower.

He hadn't forgotten his original purpose for coming here; even before entering the underground space, Aiven had dispatched hundreds of "hairy flying insects" across the entire Wizard Tower.

The structure of this "Curse School" Wizard Tower was quite traditional, similar to the "Waterfall Hill High Tower," divided into two underground floors and seven above-ground floors.

Underground floor two was where he was currently located, and underground floor one was where the Summoning Well, Ritual Platform, and prison were.

The above-ground floors, from one to seven, respectively contained the public activity room, living area, internal ecosystem, laboratory, library, Tower Master's quarters, loft (Tower Spirit).

After the vision shift, Aiven arrived at the third floor's "internal ecosystem." Once expanded, this floor reached an astounding 40 hectares.

Most areas were lush with demonized vegetation—poison arrow wood, human ear fungus, ghost face grass, corpse tuber—but at the center stood a granite-constructed ancient fortress.

A large group of tall ghostly figures wielding beheading giant swords and wearing blood-soaked hoods; terrifying "little devils" with black horns painted with white spells and sinister expressions; twisted white evil spirits crawling like spiders...

Firmly guarding this place.

But in front of Aiven, these terrifying things were utterly ineffective.

Transforming into a wisp of wind, he slipped into the interior of the fortress, which served as the bankers' temporary treasure trove.

Without much effort, amongst piles of extraordinary treasures shimmering with spiritual light, he found a dazzling golden Compass.

Clearly, they hadn't been to the "Golden Kingdom," and were unaware that the "Golden Compass" concerned the secret "behind the door."

If they had known, they wouldn't treat it so casually.

Immediately, using a series of practical knowledge from "100 Common Evil Curses," "Adventurer's Self-Cultivation," "Wizard's Exploration Guide," "How to Open a Coffin Gracefully," "Wizard Tower Guide Collection," Aiven confirmed there was no issue with the Compass itself.

And reached out to take it in hand.

However.

Ah—!

Located on the underground second floor, those three beautiful female heads mounted on the camel suddenly opened their eyes together and emitted an extremely harrowing and piercing scream.
