Security Testing

Matthew stood on the floor piled with discarded manuscript papers, clutching the medicine tightly in his hand.

The bloodline potion, finally created after twelve revisions, now flowed slowly within the glass tube as if it were alive.

【Name: Flame-Eating Wyvern Bloodline Potion】

[Ingredients: Flame-Eating Dragon Essence Blood, Moonlight Moss, Dewdrop Grass, Abyssal Salt Crystal Powder, Glowing Spores...]

[Note: This product contains Flame-Eating Wyvern Blood Essence. Large doses may awaken the Wyvern bloodline and even trigger uncontrollable physical mutations. Please use with caution.]

[Unrefinable; the item's purity has reached its limit.]

Matthew stared at the potion, hesitated for a moment, and did not rush to drink it.

Although he successfully refined the Bloodline Potion, it was his first time refining it, and the potion's effects were still unknown.

Trying it rashly might cause some adverse reactions; the safety of the bloodline medicine must be tested first.

After a moment's thought, Matthew put on his wizard's robes and went out the door.

……

In the trading markets of the four major schools' headquarters, there is a section specifically for selling living creatures.

This place mainly sells creatures native to the Winter Realm.

Matthew walked through the market and headed straight for this spot.

"grown ups!"

A humanoid male of a different race bowed respectfully upon seeing Matthew's arrival.

He wore a metal collar around his neck, his skin was pale blue, and his cheeks were covered in fish scales.

"My name is Tru, what can I do for you?"

Matthew nodded and said, "I need to purchase some creatures."

"Sir, this way please."

Tru led the way with his head down the whole time, the metal collar on his body making a clinking sound.

The two walked through a long corridor and came to an open space.

Before me were several rusty iron cages, crammed with all sorts of creatures.

Most of the creatures in the cages had blank expressions and showed no reaction to Matthew and his companion's arrival, seemingly having become accustomed to it.

"These are all top-quality specimens whose physiques far surpass those of their kind. If you take a fancy to one, just tell me."

Matthew inspected each creature in the cage.

Each creature had a metal tag around its neck with numbers on it, which appeared to be their price tag.

He had never seen most of the creatures here before, but there were some exceptions.

For example, the Snowtooth Clan, whose entire bodies are covered in fur except for a pair of fangs, and the Bloodclaw Beast, whose skin is crimson red.

These creatures were selected because they all appeared to be quite strong, making them suitable for testing the bloodline potion.

only……

Matthew glanced at the price and shook his head.

He must observe the body's reaction after the test subjects take the bloodline drug and adjust the drug accordingly.

Therefore, he needed a large number of experimental subjects to serve as controls, and the price of these organisms far exceeded his budget.

Matthew sighed. "Change the batch!"

Seeing Matthew's dissatisfaction, Tru suddenly thought of something and slapped his forehead.

"I understand, sir. Please follow me!"

Led by Tru, the two crossed the path and soon arrived at another open space.

It was still a huge cage, but the situation inside was completely different from before.

The creatures in the cage were all females with beautiful faces and outstanding figures.

Tru gave Matthew a knowing look and explained with a smile.

"My lord, these are all female humanoid creatures unique to the Winter Realm."

"There are cat demons, rabbit demons, centaurs, octopuses..."

Matthew waved his hand, interrupting.

"I need some test subjects, live ones, in large quantities, and the cheaper the better..."

ten minutes later……

Matthew left the biological market carrying a cage of furry rodents.

……

Soon, Matthew returned to his cabin.

He encountered no accidents along the way and placed the rodents he had bought on the experimental table.

This cage of rats cost one magic stone fragment and contained forty-eight rats, just enough for experimenting with bloodline potions.

In the wizarding world, wizards often use gray-jawed rats and sharp-toothed rats for experimental research.

These rodents have a collective name: laboratory mice.

Because of their high reproductive rate and ease of raising, they have always been the first choice for wizards' experiments.

However, unlike the wizarding world, the cage of rodents in Matthew's hands was bred from the Frozen Moss Rats, a species unique to the Winter Realm.

Matthew eagerly took out two frozen moss mice and labeled them number one and number two respectively.

Then they were injected with different doses of the Flame-Eating Dragon Bloodline Potion.

Two hours later...

"Roar!" Hot air billowed from the mouth of the first laboratory mouse, and the sound was somewhat like the roar of a dragon.

The eyes of the second experimental mouse became vertical pupils, the bones under the skin bulged high, and its two claws became more curved and sharper.

At this moment, both laboratory mice lost their minds and began to bite each other frantically.

"It seems that both of these laboratory mice are mutating in a direction that is out of control."

Matthew shook his head, waved his hand, and used "Vine Growth" to strangle the two failed attempts.

He then picked up the manuscript of the Bloodline Potion formula and began to adjust it again.

After an unknown amount of time, Matthew took out two more frozen moss rats and began injecting them with the adjusted bloodline potion.

And so, he immersed himself in the final safety tests of the Bloodline Potion.

……

Five days later, the experimental table was covered with the corpses of frozen moss rats.

Apart from……

The two lab mice that are still alive.

At this moment, numbers 47 and 48 are in their cages, running around excitedly, looking quite energetic.

Matthew gripped a vial of medicine tightly, staring down at the dark red liquid inside.

"This time there won't be any problems."

After several days of observation of the two mice and a series of tests, he finally confirmed the safety of the bloodline drug.

He used all the blood of the Flame Devouring Dragon to make bloodline potions, a total of eighteen bottles.

"All the hard work these past few days has finally paid off."

Matthew looked at the bloodline potion on the table, and the more than forty frozen moss rat corpses beside it.

In a daze, his memory returned to that scene.

He saw the woman with her hands wrapped in bandages again...

And its predecessor, lying on the cold experimental table...

At that time, his fate was probably like that of these frozen moss rats.

"You must...survive!"

Matthew took a deep breath, uncorked the bottle, and scalding hot steam billowed out of the glass bottle.

Let's begin!

He tilted his head back and swallowed the Flame-Devouring Dragon Bloodline Potion in one gulp.

Instantly, a wave of heat, like magma, surged from his throat down his esophagus into his stomach.

A surge of heat exploded, coursing wildly through his body, and his skin oozed a hideous crimson.

"Not enough, more!!!"

Despite the excruciating pain, Matthew grabbed another bottle of bloodline potion.

He gritted his teeth, pulled out the stopper, and forcefully poured the medicine into his mouth.

"boom--"

This time, he felt his entire body being engulfed in flames, every cell burning!

"continue!!!"

Without the slightest hesitation, Matthew grabbed the third bottle of bloodline potion.

He bit open the bottle stopper and tilted his head back to slurp it down.
