An emperor in his later years is summoned by his sister to save the nation's fate.

Ultimately, they could only be trapped and die in this cold world. However, Lu Xueyao, who was familiar with the rules, had a perfect way to counter it.

"Starving Ghost, make your move! Remember, only restrain it, do not cause any real damage!" Lu Xueyao gave the order.

"Hehe..."

The five-meter-tall starving monster let out a low roar. It did not use the Devouring Rule, but instead directly released the Monster Hair Rule that it had previously devoured and fused with.

Countless strands of black hair, as tough as steel wire, emerged from the void, wrapping around the Mirror Demon's true form, which had transformed into Lu Xueyao, and binding it in place, rendering it unable to move.

Since this entanglement is merely a physical and supernatural restriction and does not cause any destructive damage, the counter-damage rule is not triggered.

Taking advantage of the mirror ghost being restrained, Lu Xueyao flipped her wrist, and the A-grade physical ghost artifact, the Demon-Subduing Pestle, which was specially designed to deal with high-level ghosts, instantly appeared in her hand.

Without the slightest hesitation, she rushed forward like lightning, swung the Vajra Pestle, and smashed it down hard on the head of the Mirror Demon's true form!

"Bang!"

The dull thud echoed in the mirror world, triggering the absolute rule of the Vajra Pestle—any A-rank or lower-ranking monsters struck would be forced into a state of paralysis for up to 1 minute!

The mirror spirit, having suffered a severe blow, instantly dimmed the eerie light in its eyes, and its supernatural fluctuations seemed to freeze, causing it to completely freeze.

However, at the very instant the mirror went blank...

"Buzz!"

The second killing rule of the Mirror Ghost was also triggered. An invisible force of rule crossed space and descended directly on Lu Xueyao's head. The terrifying power that caused the Mirror Ghost to crash was about to act on her!

But Lu Xueyao was prepared. She raised her left hand, lifting the ancient A-grade defensive artifact, the Glazed Purification Bowl, high into the air.

This strange artifact, obtained from the Medicine Master's Glazed Palace, has the core ability to absorb and transfer the laws of killing. The moment the counter-damage arrives, the Glazed Purification Bowl emits a dazzling glazed Buddhist light, directly absorbing the invisible rules of death into the bowl.

Immediately afterwards, Lu Xueyao aimed the bowl at the mirror spirit that was stuck in a glitch in front of her.

"Here you go!"

"boom!"

The newly absorbed crash rules were rebounded intact by the Glazed Pure Karma Bowl and returned to the Mirror Demon!

As a result, the already frozen Mirror Demon was subjected to the combined impact of two A-level Demon-Subduing Pestle forced freeze rules at the same time!

This overload at the rule level instantly destroyed the supernatural balance that the Mirror Ghost maintained, plunging it into an irreversible deep crash. It could no longer even maintain its disguise as Lu Xueyao and turned directly into a twisted gray shadow.

"Now, eat it!" Lu Xueyao ordered. The starving ghost, who had been unable to suppress its appetite for a long time, immediately rushed forward.

It stretched out its hairy black hands, grabbed the deeply frozen shadow, stuffed it into its mouth, and chewed and swallowed it in large gulps.

As the Mirror Ghost's true form was completely devoured by the Starving Ghost, the mirror world, now devoid of its rules, shattered like broken glass, making a cracking sound before collapsing with a deafening roar.

Lu Xueyao's vision blurred for a moment, and when she regained her footing, she was back in the dimly lit stone house.

The starving ghost standing beside her, after devouring this troublesome A-level monster, had its black aura become even deeper.

It burped, and not only did its supernatural foundation increase significantly, but more importantly, it successfully integrated a new and powerful rule. With the help of any reflective mirror, the Starving Ghost could unleash the terrifying ability of the Mirror Ghost to pull people into other dimensions and cause simultaneous damage!

Of course, the A-grade ghost crystal was spat out by the starving ghost, after all, it was a strategic resource, and the fusion rules did not require the ghost crystal.

After resolving the crisis without serious incident, Lu Xueyao began to carefully search the stone house.

Soon, she found a fist-sized piece of unusual metal in a dusty wooden box in the corner of the room.

The metal was entirely black, devouring light, yet its surface faintly emanated a chilling, eerie power.

When Lu Xueyao picked it up and put it into her system backpack, the backpack's inventory immediately displayed detailed information about the metal.

Item Name: Abyssal Mithril

[Item Grade: S-grade material]

[Item Description: A special metal that has been immersed in the abyss of a strange source and has been imbued with higher-dimensional rules.]

[Special Effect: If Abyssal Mithril is added when forging offensive weapons, the weapon will gain the property of penetrating rules, dealing high amounts of true damage to any strange entity. Even against S-rank strange entities, it can break through their rule defenses and inflict a certain degree of damage.]

[If added during the forging of defensive armor, it can significantly increase the wearer's unorthodox defense, directly granting immunity to some unorthodox rule-based damage below Grade A.]

"This is simply the perfect material for forging magical weapons!" Lu Xueyao excitedly shared the information with Lu Li in her sea of ​​consciousness.

Upon hearing this, Lu Li nodded slightly and transmitted his voice, "It is indeed a good thing. After you return to your territory, you can use the black iron ore from the B-grade black iron vein that you mined earlier, and mix it with this abyssal mithril to forge a few handy magic weapons. Your combat power will rise to another level."

In the following period, Lu Xueyao opened the doors of more than a dozen stone houses in the surrounding area and ransacked them.

Although no further strange occurrences were encountered, and no rare or precious minerals like Abyssal Mithril were found, the exploration was not entirely fruitless.

In several stone houses that appeared to be used as warehouses, she found three sealed jade boxes, each containing one of three extremely unusual supernatural seeds.

By analyzing the system's inventory, Lu Xueyao figured out the function of these three types of seeds.

Firstly, there is a seed called Corpse-Eating Vine. This is a bloodthirsty magical plant. Once planted and mature, it can actively devour the strange corpses piled up outside its territory through its tough vines, thereby continuously growing and evolving.

If it can be allowed to grow and transform to the second stage, it can even directly devour living low-level monsters!

This is definitely the best plant to serve as the first line of defense for a territory.

Secondly, there is the seed called the Netherworld Flower. The Netherworld Flower that forms from this seed after it matures has no offensive or defensive capabilities.

However, its fragrance carries a special rhythmic pattern, possessing an irresistible and fatal attraction to the eerie atmosphere within a radius of dozens of miles.

Once the fragrance of the flower spreads, it will cause the eerie creatures to go berserk, desperately trying to break through the defenses to obtain the Netherworld Flower.

If used properly, this thing is simply a perfect monster-gathering artifact. Combined with the Soul Refining Array and Blood Transformation Array in the territory, it can definitely achieve the most efficient mass harvesting.
