Starting from Ainz Ooal Gown, simultaneously traveling through time

A few days later, in a hidden cave that had been temporarily converted into an alchemy laboratory.

Leylin "invited" several special "experimental assistants" from outside the kingdom—a few trembling goblins.

They were secured to the stone pillars with strong magical ropes, their ugly faces etched with primal fear.

Leylin took out several specially made gold-plated glass bottles from his personal space. The liquid inside the bottles displayed an eerie and magnificent color in the dim light.

Like a carefully crafted poison cocktail, it flows slowly, occasionally flashing with a dangerous glimmer.

He picked up a bottle of the lightest-colored potion, which had a pale golden sheen, walked up to a goblin, and ignoring its squeaking and struggling, pried open its jaws and poured the entire bottle of liquid into it.

The medicine takes effect immediately upon entering the throat.

"Gaaaaaah—!!!"

The goblin let out a shrill, distorted roar, its previously shriveled body suddenly tensing, its bluish-black veins bulging and writhing beneath its skin like earthworms.

Its eyes quickly became bloodshot, turning completely red, and its short limbs struggled wildly, exuding a violent and powerful aura.

Leylin calmly cast [Magic Detection] and [Life Perception].

Data shows that the energy intensity of this originally weak magical creature, which was at the lowest level (around level 1), has begun to rise sharply.

Level 2... Level 3... Level 4... Eventually, it stabilized at a level close to Level 5.

For goblins, this is a complete transformation.

But the cost is equally clear—

Its rough skin lost its elasticity at a visible rate, becoming withered and wrinkled like old tree bark, and its back hunched over.

In just a few minutes, it seemed to have completed a life cycle of decades, aging rapidly while its strength surged.

"It is initially effective, but at the cost of rapidly depleting one's life force, leading to physical aging."

Leylin observed carefully, his fingertips glowing faintly, recording the observed data and images on a specially made magic parchment scroll.

The experiment continued.

The second vial of potion, now a dark gold color and more viscous, was poured into the mouth of another goblin.

"roar--!!"

An even more violent reaction erupted.

The goblin's body swelled up like an inflating balloon, its muscles bulging, stretching its originally loose skin to the point of being almost transparent, and its bones creaking under the strain.

Its power level soared, breaking through level 5, level 8... and approaching level 10 in the blink of an eye!

However, at the very moment when its roar was at its highest, the sound abruptly stopped.

Its swollen body deflated rapidly as if air had leaked out, and its bulging eyes lost all their luster, turning cloudy and grayish-white.

Its head lolled to the side, and its life force vanished completely.

At the moment when its power reached its peak and its level reached around level 10, its life force was completely exhausted by the excessive burning, and it died of old age.

Lei Lin stepped forward to check.

The corpse's muscles were stiff as iron, and its skin was as tough as thick leather, even surpassing the hardness of ordinary orc warriors.

If it can withstand this transformation, it will undoubtedly become a rare "warrior" or even "chief" in the goblin tribe.

"There are thresholds to life strength and endurance; exceeding them will lead to collapse." Leylin wrote again, his gaze turning to the third vial of potion.

The potion had a deep, dark color, as if it were a mixture of molten gold and dark red blood. Its radiance was restrained, yet it subtly exuded an unsettling aura.

The third goblin was given the potion.

The initial reaction was similar to the previous two: roaring, muscle swelling, and bulging veins.

But soon, the situation took a sharp turn for the worse.

Its roar became low and hoarse, with inhuman "clucking" sounds rolling in its throat, and its skin repeatedly tugs between rapid aging and some kind of hardening process.

Finally, fine, hard, dark gray-black scales with a dull metallic sheen pierced its skin and covered its body!

Its hands and feet are twisted and deformed, the bones of its fingers and toes are elongated, and sharp hook-like claws extend from the ends. Its skull is deformed, its snout protrudes forward, and its mouth is full of jagged, sharp teeth.

What's most unsettling is its eyes—

His pupils contracted into cold, lizard-like vertical pupils, a layer of murky gold spreading across his eyes, filled with pure bloodlust and savagery, his reason completely gone.

It is no longer a goblin, but a dragon-like lizard monster that is nearly two meters tall, covered in scales, and exudes a ferocious aura!

"roar--!!!"

The monster's strength surged, reaching around level 15. It suddenly broke free of the magical ropes that had bound the mammoth, creating a foul stench as its claws lunged straight at Leylin's face!

Leylin's eyes remained unwavering. His long sword, which had been drawn at his waist, was now drawn, its blade flashing like a cold moon, precisely slicing into the tiny gaps in the monster's neck scales.

laugh--!

There was no clanging of metal, only the soft sound of a sharp object cutting into something. The monster's head flew up with an incredulous, ferocious expression, and the headless corpse crashed to the ground.

With a slight flick of his wrist, Lei Lin's longsword traced an arc in the air. The condensed moisture in the air automatically adhered to the blade, washing away the thin line of blood. The water droplets and bloodstains were then flung to the ground together.

The sword was sheathed in one swift motion.

He crouched down and carefully examined the corpse of the "Lizard Deadpool".

With scales that are nearly as hard as low-carbon steel, incredibly strong muscle fibers, and sharp claws that can easily tear through chainmail, this monster is a great threat to ordinary people and even ordinary soldiers.

"Lost their minds, out of control, the end of mutation." Leylin noted down the key conclusion.

The fourth goblin was given the same dark potion.

The same lizard-like transformation process unfolded, and the monster broke free of its restraints, roaring as it pounced.

This time, Leylin did not use the knife.

He raised his head and stared directly into those beastly vertical pupils.

Om-!

Invisible ripples seemed to spread through the silent cave, and Leylin's eyes ignited instantly, turning into burning golden pupils!

The dragon's aura, far purer, nobler, and more vast than the thin, chaotic dragon blood pressure within the lizard monster, descended with a deafening roar, like a tangible mountain!

"Ugh... Guh..."

The lizard monster that pounced froze instantly, its bloodthirsty vertical pupils filled with primal fear, and a terrified wail escaped its throat, its ferocious aura vanishing.

Its forward lunge posture was abruptly changed to a prone position, pressing its ugly head tightly to the ground, its entire body's scales trembling slightly with fear.

"Even if they lose their intelligence, the absolute suppression of superior bloodlines still exists... The class system of dragon society is indeed etched into their bloodline instincts."

Raylin understood, and then with a flash of light, he ended the experiment.

He conducted several more repeated and control experiments until all the "materials" were exhausted. Finally, he cleaned up all the experimental debris and put it back into his personal space.

..............................

The cave returned to silence, with only the light from the gilded lamps illuminating Leylin's pensive face.

He toyed with the last, darkest bottle of potion in his hand; the liquid swirled slowly within, shimmering with an alluring yet dangerous light.

"Based on the principles of dragon bloodline evolution potions, and adapted to the rules of this world, this is a 'Life Tempering Potion'..."

Lei Lin summarized.

"The effects are remarkable, capable of forcibly catalyzing life potential and greatly enhancing physical strength, but the side effects are extremely dangerous."

First, it drastically reduces lifespan, leading to rapid aging.

Secondly, if the recipient's willpower is insufficient or their physical constitution cannot withstand the drug's effects, it will trigger dragon blood corruption, transforming them into a mindless, instinct-driven "Deadpool" monster.

He stared at the potion, the most crucial and dangerous ingredient of which was his own highly diluted blood.

Even after dilution, the dragon hybrid bloodline factors it contains are still too potent a poison for ordinary creatures.

"My bloodline concentration seems to be quite high. Without a strong enough mental power to control it, or a special physical foundation, using it rashly would be suicide or turning into a monster."

Raylin knew that the medicine was far from being safe and practical.

"More experiments and more precise formulations are needed. Perhaps... we need to find test subjects with higher mental attributes, or add ingredients to stabilize the mind."

He put away the potion and looked outside the cave.

Goblins have provided enough data as initial experimental subjects; the next step may be to "invite" some stronger volunteers.

"You can never have too much material."

The last glimmer of golden light faded in his eyes, and his irises returned to their normal color.

He cleaned up the traces of the experiment, and his figure quietly disappeared into the night outside the cave.
