Chapter 500: Chapter 500

"How did you suddenly appear here?"

Serena looked at them coldly, enduring the excruciating pain inside her, and spoke with difficulty.

Doctor Yates smiled smugly, "Originally, Walter Coleman was the bait to lure you over and capture you, but I didn’t expect you to not follow my plan, so I had to change it!"

Something was definitely off!

Serena’s heart sank slightly, her scrutinizing gaze landed on Doctor Yates, "You used Walter Coleman as bait... what is your relationship with Walter Coleman?!"

"That’s something you don’t need to know."

Doctor Yates did not answer her, instead responding smugly.

"Now, I give you two choices: come with me obediently and spare yourself the pain, or be forcibly taken away. If you’re smart, you know what to choose!"

Originally, they thought the girl would obediently go with them, but unexpectedly...

The girl spoke with extreme arrogance.

Even at death’s door, she dared to be so presumptuous!!!

Doctor Yates’ face darkened instantly, but before he could react, he noticed Serena’s overly pale complexion and her trembling hands struggling to endure.

Her condition resembled those failure X Potion side effects...

Doctor Yates widened his eyes in disbelief, his face full of shock and confusion, murmuring.

"I didn’t expect you, a successful experiment, to also have side effects... Originally, I thought only failures would have side effects... This is extremely strange!"

Hearing him casually mention "failures," Serena’s eyes grew colder, filled with killing intent.

Those so-called failures were living children! They were the precious ones of their parents, yet they were kidnapped with despicable methods to become test subjects, living in pain daily...

Evelyn’s dying wish was for no more innocent children to endure the suffering of being test subjects.

But they were so malicious, disregarding life, and using any means necessary to achieve their goals!

"Strange, really too strange!" The rıghtful source is novelFirｅ.net

Doctor Yates kept mumbling, clearly perplexed.

But soon, the shock and confusion on his face faded, replaced by excitement and fanaticism.

"But it doesn’t matter, capturing you back can allow for careful research!"

She was the only successful experiment in years, with immense research value.

Their final experimental success was imminent!

Just thinking about it made Doctor Yates tremble with excitement, unable to wait to use her for experiments!

Doctor Yates laughed proudly a few times, then cast a venomous gaze on Serena.

"All of you, capture her!"

The group of men in black immediately responded respectfully, "Yes."

Watching Serena being surrounded, Doctor Yates sneered disdainfully, his tone full of contempt.

"Serena, stop struggling meaninglessly."

"The side effects of the X Potion are beyond your capability to resist!"

No one could withstand the torturous pain once the X Potion’s side effects kicked in!

Especially not a weak woman like her...

Doctor Yates laughed arrogantly, as if already envisioning the moment Serena was captured in disgrace.

But the next second, what happened made his expression suddenly change.

"Ah... it hurts... my leg is broken..."

The group of men in black fell to the ground in disarray, crying out in pain, their eyes full of fear towards Serena.

Facing this scene, Doctor Yates’ eyes widened in disbelief.

Serena’s face grew even paler, the pain within her body becoming more severe.

In the past, this group of people was nothing to her, but now with the side effects, she had exhausted herself to take them down.

She couldn’t hold on much longer...

But even so, Serena still exuded a strong aura.

When she slowly raised her head to look at Doctor Yates, her stunning fox-like eyes carried intense killing intent, making Doctor Yates shiver with a chill running down his spine, causing his body to tremble involuntarily.

She could still resist despite the C Potion’s side effects!

This was truly unbelievable!!!

"Oh... you really are full of surprises!"

After recovering from his shock, Doctor Yates’ eyes filled with even more excitement, nodding in satisfaction.

No wonder she’s their successful experiment, far better than those failures!

"Don’t be afraid, continue to attack, she won’t hold on much longer!"

The group of men in black, enduring their pain, stood up and cast a grim gaze on Serena.

Serena’s face was deathly pale, but her gaze was extremely cold.

In her current state, direct conflict was of no benefit to her, perhaps...

"Hahaha, you still ended up in my hands!"

Seeing Serena being tied up, Doctor Yates, though surprised at this time’s ease, soon laughed triumphantly again,

"Serena, I told you, you can’t beat me!"

The girl’s face was pale, but her eyes were unusually dark.

As she spoke, before Doctor Yates could react, a silver needle glinting with a cold light suddenly shot towards Doctor Yates’ neck.

"Doctor Yates, watch out..."

If it weren’t for the quick reflexes of the Hidden Guard by Doctor Yates’ side, pulling him away in time, that silver needle would have pierced Doctor Yates’ main artery.

Doctor Yates’ face turned pale with fright, then he flew into a furious rage, his gaze towards Serena filled with a murderous intention.

"You damned wench, you dare to attack me!"

A hint of regret flickered in Serena’s eyes. If not for the side effects affecting her, that needle surely would have taken his life!

Recalling how close he came to death, Doctor Yates was filled with fear, followed by a rising anger. He took out a potion from his backpack, speaking insidiously.

"Heh, let’s see if you’ll still be so disobedient after being injected with the Catalyst!"

The Catalyst would amplify the X Potion’s side effects, making the pain a hundred times worse.

The X Potion’s side effects were already unbearably painful, let alone a hundredfold increase, no one could endure that!

By then, Serena would surely be unable to bear the pain and would beg him for mercy!

With this thought, Doctor Yates let out a sinister chuckle.

As the icy potion was injected into her body, Serena instantly felt the surging pain inside magnify a hundredfold. Even she was on the brink of fainting, her body curling up from the intense pain.

"Hahaha, take her away!"

Doctor Yates’ voice rang out in triumph.

"Once back at the base, immediately begin the experiments and research on her!"

She couldn’t let them take her...

Serena tried to break free from their grasp, but her limbs were weak, and the corroding pain grew increasingly severe. Just as she was about to lose consciousness, the door was violently kicked open.

She heard an urgent male voice.
