Under the shadowless lamp.
As a large amount of blood was pumped into his body, the head of the person before them was growing rapidly.
In less than thirty seconds, the severed head had already grown back.
The middle-aged man, having regrown his head, was no longer in a coma, and his entire body began to struggle and howl violently!
His blood-red eyes brimmed with endless fear.
It seemed this was not his first time experiencing such an ordeal.
"Ahhh!!! Let me go! Hurry, let me go!!"
"I won't dare to drink blood ever again, I won't dare to!
Please, let me go!
I know I was wrong!
Please don't torture me anymore... Ask me whatever you want to know, I will tell you everything!"
"Ahhh—"
The piercing scream made Matthew Lawrence frown.
Seeming to notice the change in his boss's mood, Dr. William Birkin glanced at the experimenters outside the tempered glass: "Make him quiet down."
As soon as he finished speaking,
the machine controlling the sedative injection began to pump frantically into the middle-aged man's body.
Only when the man ceased speaking and his eyes became hollow and listless again did the operation outside the glass stop.
Following this, Dr. William Birkin conducted a series of even more brutal experiments on the man.
Severing hands and feet was already considered a "minor injury" in Dr. William Birkin's hands.
So much so that this cruel scene made even Matthew Lawrence frown, and he simply went outside to stop watching the testing process.
Soon, Dr. William Birkin finished the series of tests on the middle-aged man.
The results were unanimously that "the subject possesses an extremely high degree of regeneration," and there wasn't even a scar.
After finishing all this, Dr. William Birkin put down the various 'torture instruments' in his hands: "According to the experimental tests, the new experimental subject will regenerate rapidly under conditions of sufficient blood supply; it will not die whether its heart is pierced or its head is severed."
"I suspect..."
"You suspect he is a Vampire from mythology, right?" Matthew Lawrence, outside the glass wall, interrupted what Dr. William Birkin was about to say.
"Yes." Dr. William Birkin nodded seriously.
"In that case... then we should just test it with pure silver." Matthew Lawrence suggested.
He then said aloud: "There is a medieval greatsword made of pure silver in my office, placed on the bookshelf display case; find someone to retrieve it."
In the Marvel World, the species known as Vampires does indeed exist, originating from the once highly popular hit IP 'Blade'.
Because of this, Matthew Lawrence did not rule out the possibility that elements from that hit IP had been integrated into the current World.
Under Matthew Lawrence's instruction.
Before long, an experimenter retrieved the medieval greatsword that served as an ornament.
Taking the greatsword, Matthew Lawrence walked back into the experimental area and looked up at the unconscious middle-aged man.
Without any hesitation!
Swish—
A flash of silver sword light!
The man's five fingers were severed at the root.
But this time... no matter how the experimenters injected blood into the man's body, the wounds on his palm did not heal, instead presenting a cross-section similar to being scorched by Fire.
Seeing this scene, Dr. William Birkin's eyes widened!
An indescribable look of madness appeared on his face!
"I didn't expect it to be real!!"
"I didn't expect that the species of Vampire really exists in the World! Hahahaha!"
For Dr. William Birkin, there was nothing better than discovering a better experimental subject.
If there was, it would be that his experiment was successful.
"Pause the sedative injection and let him wake up." Dr. William Birkin ordered outward.
Immediately, a creepy smile appeared on his face; under the pale light, that gloom and madness were displayed even more vividly.
"Didn't he say that he would tell us whatever we want to know?"
"Very well! Then we will ask for the location of his companions, and when the time comes, we will capture them all!"
"An experimental subject that comes with super-strong repair capabilities might just become the key to this experiment's breakthrough."
The first thing the middle-aged man did upon recovering from his coma was to struggle and scream wildly.
Especially after seeing the injury on his palm, his struggle became even more intense...
"Please! Don't kill me! I know I was wrong, I shouldn't have attacked you!"
"But I was really too hungry, really too hungry..."
"Wuwuwu— I'm sorry! I'm sorry!" The man's face was filled with fear, and tears kept streaming down from the corners of his eyes.
Facing the man's pleas, Dr. William Birkin's face turned to wear a kind smile, and he gently consoled: "Don't be afraid. This time I won't hurt you; I just want to ask you a few simple questions."
"If you can answer honestly, I will let you go back. What do you think?"
"Really?" The man's eyes widened, as if he had heard something incredible.
"Of course it's true. Would I lie to you?" Dr. William Birkin was like a creepy uncle luring a child with a lollipop, his tone exceptionally gentle.
"Then feel free to ask! As long as I know it, I will say it! I only beg you to let me go!"
At this moment, the man was like a drowning person clutching at a straw of life; although he had distrust in his heart, he dared not hesitate at all, fearing that this life-saving straw would vanish in an instant.
"Very well, I will ask you."
Dr. William Birkin did not beat around the bush and got straight to the point: "—Where are your companions?"
Upon hearing this question, the man's body trembled, and a flash of panic crossed his eyes.
Just as he was about to say something, he was interrupted by Dr. William Birkin again.
"Don't be in such a hurry to answer me."
"You should be clear about the consequences of answering incorrectly, so think clearly about how you should answer this question next."
"Now, speak."
Under the cold-toned light, Dr. William Birkin's stiff smile made people feel extremely terrified.
Cold sweat dripped from the man's forehead, and he swallowed nervously.
"I... I..."
He looked up at Dr. William Birkin's face, then glanced at the blood-stained 'torture instruments' on the side.
Finally, he made up his mind.
'I'm sorry... I'm sorry! Please forgive me!'
'I really can't take it anymore. I don't want to be tortured here for the rest of my life... And I definitely don't want to be their experimental subject.'
'So...'
"I'll say it... I'll say it all." The man suddenly deflated.
This time, he did not hesitate at all and very honestly revealed all the locations of the dozens of companions he knew.
His eyes were filled with a desire for life, without a shred of guilt.
After he had said dozens of locations all at once, he finally managed to shut his mouth.
"Is this all?" Dr. William Birkin, who was recording the locations on the side, confirmed.
"Yes." The man nodded.
Seeing Dr. William Birkin looking at him with disbelief, he hurriedly explained: "These... these are really all the locations I know!"
"The number of our kind is very small compared to humans, and because we don't want to attract the government's attention, we rarely contact each other. These are already the locations of all the clansmen I know."
"Is that so..." Dr. William Birkin frowned and rubbed his chin, then turned his head and smiled.
"Yes, I believe you."
"Then can you let me go now?" The man looked at Dr. William Birkin with hopeful eyes.
However, this time, Dr. William Birkin did not respond.
Instead, he turned his head to look outside the glass wall and shouted coldly: "Re-inject the sedative for the experimental subject."
"!!!"
"No, no, no! You can't do this to me! You can't do this to me!!"
"You treacherous bastard! You will go to hell! You will go to hell!!"
Listening to the frantic shouts and curses behind him, Dr. William Birkin was not affected in the slightest and strode outward.
After handing the recorded addresses to Matthew Lawrence, Dr. William Birkin's face was already full of fanaticism.
"Boss, please issue the capture order!"
"I want to capture all these rats hiding in the sewers!!"
