Full health is the kill threshold, no matter if you're a god or a demon!

As everyone's gaze swept over the display shelves, their breathing involuntarily became heavy.

They saw:

A massive cannon with an intricate structure and an astonishingly long barrel is projected, its muzzle brimming with energy that distorts space. With a single blast, the towering city walls in the distance crumble like sandcastles! Below is the design blueprint for the [Magic Phase Cannon - City Defense Destruction Type].

A towering mage tower, constructed of pale white bone and eerie green gems, is projected. Its summit releases a dense, dark green cloud of mist; wherever the cloud passes, the earth turns to scorched earth, and all living things wither and decay!

Projecting a device consisting of multiple nested metal rings with a complex crystal array suspended at its center, the device activates, causing localized dark clouds to gather, thunder to rage like dragons, or meteor showers to fall from the sky! Tag: [Celestial Controller (Tactical Grade)] Principles and Blueprints.

A massive circular magic circle, carved into the ground and composed of countless abyssal runes, illuminates the ground, forming a stable spatial portal from which ferocious otherworldly creatures or fully armed legions surge forth!

And there's more...

The [Global Shield Generator] is capable of creating a continuous energy barrier that covers the entire city;

The [Legion Shockwave Projector] allows for stealth underground movement and surprise attacks;

The [Elemental Silence Field] is capable of interfering with or even controlling all magical elements within a certain range;

And a large number of crucial "technical blueprints" such as the design of supporting magic power supply lines, rune engraving techniques, and rare material processing technologies.

These are not ordinary weapons.

Rather, it is a strategic weapon blueprint capable of changing the fate of a war or even a power, and the complete technology that supports the realization of these blueprints!

This is Arachne's precious yet dangerous legacy—her strategic arsenal and treasure trove of knowledge!

The survivors, standing amidst these silent yet seemingly roaring blueprint projections, were so shocked they were speechless.

The power displayed in these projections far exceeded their previous understanding of "player power".

Wu Zhan walked step by step to the display shelf closest to him.

His gaze fell on the partially unfurled metal scroll, covered with dense ancient characters, geometric patterns, and energy circuits...

He reached out, his fingers trembling almost imperceptibly, and gently stroked the cool surface of the scroll.

Then, he picked it up.

heavy.

It's not just the weight of the material, but the "weight" it carries that can shake the future.

He raised his head, his gaze slowly sweeping over his companions.

Everyone was wounded, their clothes were torn, and their faces showed exhaustion, but at this moment, their eyes shone with an astonishing light under the [Illumination] spell.

Wu Zhan took a deep breath, suppressing the sob in his throat.

He raised the metal spool in his hand, his voice hoarse and trembling with excitement and a surge of emotions:

"Brothers..."

"It seems..."

"We've found the future!"

Everyone knew what these things meant, and their faces were flushed with excitement.

Although no one said it aloud, everyone was blaming Yelena in their hearts.

But if Yelena hadn't triggered that mechanism, the group might not have been able to get into this room containing so many strategic weapon blueprints.

This truly is a case of fortune and misfortune intertwined; danger and opportunity coexist.

Everyone carefully put away the design drawings. Sun Yao glanced around the room and asked uncertainly, "Are we...once over on our adventure?"

"I...I guess so?" Han Lesheng leaned against the metal base of the display shelf. "That skeleton just now, didn't the system say it was the 'Ultimate Boss of the Secret Realm'...?"

"But..." Yun Xiangrong's slender eyebrows furrowed slightly, "The fragments of the secret realm's background that we initially obtained, those scattered stone carvings and inscription fragments, the floating city lord repeatedly mentioned, the legendary archmage who single-handedly created this place, his name is—"

"Arachne," Wang Mu continued, "but what was that lich we just blasted to smithereens called Kel'Garderoth?! Those are completely different names!"

"It's not just the name," Jiang Yi added. "The backstory clearly states that Arachne underwent an irreversible fusion with her spider companion during the experiment, becoming a 'half-human, half-spider' 'Webweaver'."

"The genders don't match either." Yelena crossed her arms. "Arachne is female. And that lich is clearly male, probably one of the city lord's subordinates."

"So, we might be facing a boss even more powerful than the Lich?" someone exclaimed.

"I don't think so. The final boss has been defeated, so the city lord probably won't show up."

"I think so too. It's legendary level, after all. Will it reappear as an eternal level? Hahaha."

"Hey, that joke isn't funny at all."

"Come and see!" Liu Nian looked up; he had already pieced together all the diaries.

The seemingly chaotic dark patterns on the back of the four pages of the diary came alive as if infused with life and magic the moment they came into contact and formed a complete plane.

The dark patterns flowed and recombine on their own, emitting a soft and stable pale blue glow, ultimately forming a map!

The crowd quickly gathered around, and the main outline of the map was clearly the inverted cone-shaped floating city where they were!

From the top-level "Observatory" and "Energy Tuning Layer," to the "Cultivation Experiment Zone," "Resource Gathering Layer," and "Knowledge Temple Layer" they had experienced, to the "Energy Core Zone" where they had just fought the lich, and now to the "Ultimate Armaments Exhibition Hall," each area has precise magical markings.

In the lower center of the map, an extra space is clearly outlined!

The outline of that space resembled a precisely nested geometric core, with a line of small text marked beside it:

【The Web-Weaving Royal Court: The Core of an Unfinished Dream】

Even more striking is the dotted path shimmering with a faint golden light, extending from the "Armor Exhibition Hall" where they are currently located, pointing directly to the hidden "Weaving Net Royal Court"!

"It seems this is the final hurdle!" Wu Zhan slowly exhaled a breath of stale air, shifting his gaze from the map and the core to the team members surrounding him.

After resting, everyone had recovered and their eyes were filled with excitement.

"Brothers, let's go!"

The group quickly regrouped and, following the dotted line on the map, left the strategic blueprint repository and entered the deepest part of the library.

After passing through a narrow passage where the bookshelves had collapsed and been buried by the violent shaking, and bypassing several unstable energy disturbance zones, the group finally stopped in front of a seemingly ordinary wall.

This wall is no different from the rest of the library: it is constructed of a heavy metal frame and magically treated gray-white stone, covered with a lot of dust and engraved with long-faded decorative patterns.

Is this the place?

Someone spoke up.

Almost simultaneously, the dust and ancient paint on the wall in front of them vanished like a phantom, revealing a line of text:

"First question: I pursue 'eternity,' so what is the medium for this fusion?"

Four options then appeared:

A. The Heart of the Astral Behemoth

B. The Core of the Ancient Elemental Lord

C. Dimensional Spider 'Nia'

D. Symbiotic spirits of leyline crystals
