The third underground level of the Extreme Martial Arts Hall, a top-secret biological laboratory.
The air here was forever permeated with the scent of disinfectant and preservatives.
Under the pale, shadowless lights, Dai Mubai was secured to a cold metal operating table by several thick, high-strength alloy chains.
Wearing nothing but a thin pair of shorts, the muscles exposed to the air trembled slightly from sheer terror.
Several researchers in white lab coats stood around him.
They wore masks, their gazes as cold as if they were observing a laboratory mouse.
"Target's vital signs are stable; we may proceed with subsequent testing."
One researcher nodded to an assistant while making notes. "Begin injection of the No. 3 Mutant Canine Beast Gene Extract."
A thick needle was ruthlessly plunged into Dai Mubai's vein.
The pale green, unidentified liquid surged instantly through his blood and into every limb and bone.
"Ugh, ahhh—!"
Dai Mubai jerked his neck back, letting out a scream of extreme, harrowing agony.
He felt as if boiling magma had been poured into his veins, with thousands of ants gnawing at his bone marrow. That pain was ten times more intense than when he had been forced to absorb Cosmic Origin Energy.
His body began to undergo a terrifying mutation.
His once-brilliant golden hair fell out in large clumps, replaced by a layer of coarse, hard black fur that rapidly covered his cheeks and chest.
His finger joints emitted a teeth-gritting sound of dislocation, and his nails grew wildly outward, curving into sharp, deformed beast claws.
"Let me go! I beg you, let me go!"
Dai Mubai was covered in tears and snot. In this cold laboratory, he pleaded desperately, even willing to spill every secret he knew in exchange for release.
Before Jiang Nian had sent him to the laboratory, he had told him that to end this suffering, he only needed to answer one question.
Which faction had sent him, where did he come from—confess everything, and he would be granted a quick death.
Yet, every time the words "Douluo Continent" rose to his lips, he felt a wave of terror.
If he spoke, he would die instantly.
If he didn't, he would endure torture worse than death right here.
"Vitality is tenacious; gene rejection is within controllable limits." The researcher's cold voice sounded again. "Prepare for the next stage of the experiment. Switch to the Iron-Armored Scorpion Venom Mixed Reagent."
The suffering continued day after day in the underground laboratory.
Various untested monster Gene Serums and unknown plant extracts were continuously injected into Dai Mubai's body.
He was treated entirely as a test subject.
As time passed, many horrifying mutations occurred on Dai Mubai's body!
His facial bones protruded forward due to genetic mutation, and interlocking fangs grew from his mouth. His legs became thick and bent, completely losing the ability to walk upright like a human; he could only crawl on the ground like a beast.
From his initial weeping and begging to his later harrowing screams, Dai Mubai eventually lost even the strength to cry out.
He became numb.
Every day, he lay like a pile of mud in a stained iron cage, clinging to life.
Waiting for the experiments that were inflicted upon him time and time again.
As the one-year deadline for his return to the Douluo Continent drew closer, Dai Mubai's turbid, yellowed beast eyes began to fill with a thick, unshakable hatred.
He hated!
He blamed all the inhuman torture, humiliation, and despair he had suffered over the past half-year entirely on Cuihua!
If Cuihua hadn't met that War General Class teacher; if Cuihua had just been bitten to death by a monster in the Wilderness Zone... then how could he have fallen into this state of being a half-human, half-beast monster!
It was all that lowly village girl's fault!
This twisted logic became the only motivation supporting his survival in this hellish laboratory.
Half a year passed in the blink of an eye amidst the day-to-day research.
On this day, the daily data collection was being conducted in the underground laboratory as usual.
Several researchers gathered in front of Dai Mubai's iron cage, using various instruments to scan his deformed body. Dai Mubai, who had completely shed his human form to become a beast, suddenly moved.
He slowly lifted his head, which was covered in black fur and fangs.
Under the stunned gazes of the researchers, a hair-raising, hideous smile suddenly twisted across Dai Mubai's strange face.
"Hehe... Hahahaha!"
Dai Mubai's vocal cords had long been destroyed by the drugs, making his laughter hoarse and grating.
He lunged at the thick iron bars, his beast claws striking sparks against the metal. Staring at the humans in white coats outside, he laughed wantonly.
"You bunch of idiots!"
As Dai Mubai laughed wildly, turbid tears streamed from the corners of his eyes, his demeanor reaching a state of absolute madness. "You at the Extreme Martial Arts Hall think yourselves incredibly clever, but in reality, you are nothing but a bunch of fools!"
"You've all been played!"
The lead researcher furrowed his brow, immediately pressed the alarm button, and shouted, "The test subject's mental state is abnormal! Prepare high-voltage electric shocks immediately and inject him with a sedative!"
Just as several guards rushed forward wielding electric prods, it happened.
Without any warning, a peculiar white light, pure to the extreme and appearing almost tangible, suddenly projected from the void.
This white light completely ignored the hundreds of meters of super-alloy dome at the Extreme Martial Arts Hall headquarters, ignored all energy defense shields, and descended directly into the iron cage in the basement.
The white light completely enveloped Dai Mubai's massive, deformed body.
Dai Mubai's wild laughter came to an abrupt halt.
His body rapidly faded within that white light, much like a bubble under the sun.
In a mere two seconds, the white light suddenly contracted and then vanished into thin air without a trace.
The sturdy iron cage was left completely empty, not even a single black hair remaining; the half-man, half-beast monster had evaporated into thin air right under the eyes of all the experimental staff!
The entire laboratory fell into a state of panic.
The lead researcher's face turned deathly pale, sweat instantly soaking through his back as he scrambled to grab the communicator and connect to the supervisor's private line.
"Supervisor! Something happened! Test Subject No. 9 was suddenly taken away by a beam of light! He disappeared completely out of thin air!"
A few minutes later, Jiang Nian rushed out of his office with a livid expression.
The supervisor in charge of the experiments had just told him that the test subject he had sent over, Dai Mubai, had suddenly vanished into thin air!
At first, he had assumed it was a joke.
But soon, after confirming it repeatedly, he realized this was no joke, but a fact that had truly just occurred at the Extreme Martial Arts Hall!
A test subject disappearing into thin air—this event, which defied the laws of physics, instinctively filled him with a sense of intense unease.
