Outer Gods invade, stuff them all into your equipment inventory.

By this time, Sean had already left the monster's lair.

The moment Cheng Jiyuan successfully controlled the ancient armored BOSS, it meant that the monster's lair had been successfully conquered.

At the center of the platform, above where the ancient armor originally stood, ripples spread silently through the space.

Spatial energy rapidly condensed and stabilized, transforming into a stable, oval-shaped portal emitting a soft white light.

The moment the portal stabilized and took shape, Sean stepped into it without hesitation.

As the light shifted and the sensation of spatial displacement washed over him, he found himself back on the familiar silver plains.

He quickly scanned his surroundings and realized that he was in the vicinity of the entrance to the newborn monster's lair, where he had previously detected the abnormal dimensional fluctuations.

However, all around was silent.

Apart from himself and the rapidly fading and disappearing portal behind him, no one saw Cheng Jiyuan and the others emerge from here.

"The same monster's lair usually has several different, randomly distributed spatial anchor point entrances."

He muttered to himself, reviewing what he had learned.

"It seems that the entrance that Uncle Cheng's team triggered and entered into the nest was not the same one that I entered."

After successfully conquering a monster's lair, the generated "safe exit" portal will most likely send the hero back to the vicinity of the entrance they initially entered. This is a common world rule.

Sean did not feel regret.

He never intended to formally acknowledge Cheng Jiyuan and the others at this time.

The identity of "Mirror" has already fulfilled its mission.

Now, it's time to "retire gracefully" and let this persona temporarily disappear into the background.

With a wave of his hand, Sean produced a ball of light.

"The Heart of the Monster's Lair..."

The moment Cheng Jiyuan successfully controlled the ancient armored BOSS, in addition to the teleportation portal, the heart of this monster's lair also materialized.

Sean took it as he left.

It is about the size of a fist, crystal clear, and contains a liquid, silvery-white light flowing inside.

"It was an unexpected surprise."

Sean put away the Heart of the Nest with satisfaction.

This can be considered as a small "hardship fee" he earned for himself while "helping others".

This "Heart of a Monster's Nest" is the crystallization of the core essence, primordial power, and some rule permissions of a successfully conquered monster's nest of a certain size or potential.

"Similar to a rare item, but even rarer..."

Not all monster lairs can gather the Monster Lair Heart.

"But I don't know what the purpose of this monster's lair heart is."

Each monster's lair heart has a different function.

It could be a powerful, sustainable seed for producing specific resources in a "micro-scale demiplane";

It might be a legendary item with effects in a specific area;

It may be a "book of rules" that records ancient knowledge or lost skills related to the nest;

It could also be a "domain barrier" that can be temporarily deployed to provide powerful defense or amplification;

It might even be a "key" or "coordinate" leading to ancient ruins or other monster lairs related to this nest...

Unless professional analysis is conducted, the true purpose of this Heart of the Nest is impossible to discern.

"Luckily, I have an equipment slot available."

The notes he had previously equipped in the third equipment slot had already been absorbed, but he hadn't put any other notes in it yet.

This is the perfect time to identify the specific attributes of the Demon's Lair Heart.

Without hesitation, Sean guided the ball of light to "place" it in the third empty equipment slot.

Instantly, a strange feeling welled up in my heart.

A clear and profound "message" surfaced in Sean's perception, instantly making him understand the core attributes and application of this Nest Heart:

[Heart of the Ancient Silver Wars (Not Fully Activated)]

Its core essence contains the fundamental rules of an ancient nest related to the Silver Race.

Basic functions——

By deeply integrating with a piece of equipment, one can attempt to permanently imbue that equipment with some of the core rules of the Heart of the Nest.

This grants them special attributes and growth potential related to the "Silver Race".

"Integrated into a piece of equipment, granting it attributes specific to the Silver race..."

Sean's eyes flashed, and he instantly grasped the application direction that interested him the most.

This means that he can choose a piece of equipment with potential and "upgrade" it with the Heart of the Nest, giving it special abilities related to the origin of this monster's nest.

His first thought was of the body of an elite bladed sorcerer.

This remains granted him the core skill "Blade Demon Resurrection," allowing him to resurrect Blade Demons using monster corpses as materials.

These Blade Demons are powerful in combat, but their biggest weakness is that, apart from the basic "Frenzy" state, they have almost no class skills.

The combat style leans towards primal fighting relying on extremely high attributes.

"The Silver Race... their class system—swordsmen, axemen, archers, knights, and the complete combat skills, formation coordination, and even aura abilities they represent..."

"Could this be considered a systematic, inheritable special ability highly related to the essence of this monster's lair?"

Sean's mind raced.

If it were fused with the body of an elite Blade Wizard, would it allow the Blade Wizard resurrected by the Blade Wizard spell to inherit its class?

"It's worth a try."

Even if we fail, it's just a waste of a monster's lair heart.

To be honest, for Sean, the Heart of the Monster's Lair was a windfall.

Having it is great, but not having it isn't a loss.

Given his current growth rate and ability to acquire resources, he simply doesn't care about the gain or loss of a Nest Heart.

But if it succeeds...

Sean's gaze turned intense.

"That would allow the skill 'Blade Demon Resurrection' to undergo a qualitative leap."

"It's no longer simply about resurrecting 'blade demons' that have attributes but only know how to fight brute force..."

"Or should they have a chance to 'inherit' the Silver Race's class template at the moment of resurrection?"

This possibility made Sean's heart beat a little faster.

If this can be realized, then "Blade Demon Resurrection Technique" will transform from a skill for rapidly producing troops into a terrifying strategic capability that can create small, specialized combat legions.

The value and practicality of this skill will be enhanced immeasurably.

The value of this monster's remains can be increased significantly.

"It's just a try, what's there to be afraid of?"

Sean finally made up his mind.

He was never one to be timid or hesitant, especially when faced with an "attempt" where the benefits far outweighed the risks and the consequences of failure were entirely bearable.

Opportunity often favors the brave who dare to try.

"And I am that kind of hero."
