He was so persuasive that he actually practiced extraordinary

Because Zhang Haiyan's words were absolutely accurate, to ensure that nothing went wrong, he would absolutely not hesitate to kill anyone.

— Clap clap clap clap.

"Indeed, she is the woman I once loved; she understands my ruthlessness."

After saying that, the black cat sighed softly, looking at the empty research institute with a rather helpless tone.

"It is indeed troublesome not having hostages, but it doesn't matter, as long as I can get what I want, that's enough."

"Come on, it's time for you to pledge your loyalty to K2."

As he spoke, he suddenly noticed that Secretary Yao's expression was somewhat unnatural, and he couldn't help but frown slightly.

"Why aren't you saying anything? What happened to your neck?"

Secretary Yao glared fiercely at Zhang Haiyan, her voice hoarse and strained, sounding as if it had been burned by charcoal.

“If Black Cat didn’t have a use for you, I would have killed you long ago.”

The black cat instantly understood, looked at Zhang Haiyan, and smiled nonchalantly.

"Hehe, it's been so many years, your temper has become quite fiery."

Zhang Haiyan gave a disdainful snort.

"I'm already being very lenient by not killing her. You should keep your mouth shut, talk less and do more."

Black Cat nodded in agreement: "Indeed, talkative assassins are not very likable."

Secretary Yao lowered her head and dared not utter a sound.

Zhang Haiyan turned around with a cold face and walked straight ahead.

"Stop talking so much nonsense, come with me."

Black Cat smiled and waved, and the group of people, armed with weapons, followed closely behind, quickly walking into the research institute.

But just then, a slightly anxious paging voice sounded softly in the channel.

"Report! Report! There's been an unexpected situation!"

"Two senior professors in the research institute didn't hear the evacuation notice and are about to run into Black Cat and his group!"

what?
There are still people who haven't evacuated!
Upon suddenly hearing the call over the channel, all the special forces members felt a chill run down their spines.

Zhang Beixing raised an eyebrow and asked in a low voice, "What's going on?"

The lark's voice continued to ring out.

"There are many confidential spaces inside this research institute. We must have missed some areas when we were evacuating the crowd."

Lei Zhan quickly asked, "Then what should we do with the plan? Should we send Black Cat deeper in?"

Nothing in this world is 100% certain or perfect. Unexpected events are inevitable when playing away from home, and now is not the time to assign blame.

Zhang Beixing's mind raced, but it was clearly too late.

He connected his computer to the entire research institute's video surveillance system. Just around the corner, the two old professors would have met Black Cat and the others.

"It's too late to stop it. Let's wait and see."

Just as the voice echoed through the channel, an elderly professor couple and Zhang Haiyan and others who were walking towards them bumped into each other.

After entering the video frame, Fire Phoenix team member Ouyang Qian suddenly shouted anxiously.

"Lark, those are my dad and mom! What are they doing here?"

what?
Ouyang Qian's parents?

Upon hearing this exclamation, Zhang Beixing's brows furrowed slightly.

After a brief silence on the channel, Ouyang Qian's belated voice continued to ring out.

"Oh, I remember now, my parents are both chemists. They mentioned it to me once before, but I didn't pay attention. How could it be them? Oh no, what am I going to do now!"

Lark comforted them, saying, "Don't worry, we're here, they won't be in danger."

At this moment, the black cat looked at the two elderly professors walking towards it and couldn't help but glance at Zhang Haiyan in surprise.

Zhang Haiyan was also stunned to find that there were still two people who had not evacuated.

The two elderly professors greeted Zhang Haiyan politely when they saw her.

"Mr. Zhang, what brings you here today?"

Zhang Haiyan asked nervously, "Professor Ouyang, Professor Su, why didn't you two leave?"

"Walk?"

Professor Ouyang hesitated for a moment, then suddenly realized.

"Oh, no wonder there was no one there when we came out after we finished the experiment. Turns out it was a holiday."

Zhang Haiyan chuckled dryly and said, "Yes, yes, it's holiday time, you should all hurry up and leave too."

The black cat raised its hand to interrupt her, and walked up to the two old professors with a smile.

"Professor Ouyang Song and Professor Su Ya?"

Ouyang Song and Su Ya nodded. "You know us?"

“Of course, I’ve seen your files. You are both very famous chemists,” the black cat said with a smile. “Since you’re here, why don’t you stay? I’d like to invite you to see something truly remarkable.”

As soon as he finished speaking, two masked thugs behind the black cat sprang up and pointed their guns at the two men.

Professor Ouyang was taken aback, only then realizing that something was amiss.

He quickly reached out to protect his wife, anxiously looking around for advice.

"Mr. Zhang, what's going on? Why are they all carrying guns!"

Zhang Haiyan frowned deeply. "It can't be explained in just a few words... I'm sorry, both of you, I've dragged you into this."

As she spoke, Zhang Haiyan turned around and looked at the black cat with lightning speed.

"Please let them go. Both professors are old and innocent."

what?
Innocent?
The black cat chuckled coldly, as if it had heard a very funny joke.

"Don't be silly, how could I possibly refuse a hostage that's been delivered to my door?"

"Besides, can you honestly say they didn't contribute to the core engineering work that led to the creation of Vx3?"

Zhang Haiyan roared, "They just think it's medicine!"

The black cat let out a cold laugh.

"Do you know about the Nobel Prize? Its founder, when inventing modern high explosives, claimed it was to defend world peace."

"But what does it bring?" the black cat asked itself, answering, "War! Every day, people bleed because of it!"

A cruel glint flashed in the black cat's menacing eyes.

"No one is innocent in the creation of weapons. Even if the two old professors don't know what they have created, their hands will still be stained with the blood of innocent people, just like ours!"

"Vx3?" Professor Ouyang asked, frowning. "Mr. Zhang, what is that?"

As a chemist, upon hearing the word VX, he immediately realized that something was amiss.

VX is a transliteration; it is a poison first discovered by the British in 1952.

Subsequently, the Americans chose VX as the focus of their chemical warfare agent development. The scientific name of VX is S-(2-diisopropylaminoethyl)-methylphosphonic acid ethyl ester, which is the longest name among all chemical agents.

Its lethality is also astonishing; contact with human skin or inhalation can lead to poisoning, and it can be transmitted through air or water, making it almost undetectable.

In short, its destructive power is extremely terrifying!
However, before Zhang Haiyan could speak, Professor Ouyang was met with a gunshot.

"boom!"

"what!"

Professor Ouyang screamed and fell to the ground. He had been shot in the thigh and was bleeding profusely.

Professor Su, his wife, panicked, cried out, "Ouyang! How are you?"

"Mole, don't try to play tricks on me. Just give me the stuff obediently."

Zhang Haiyan's eyes widened: "You didn't need to do that!"

"Now that things have come to this, do you really think I'll believe you?" Black Cat said coldly. Zhang Haiyan looked at the two professors with tears in her eyes, "I'm sorry, it's all my fault."

The black cat turned and waved to his subordinates, ordering, "Take them with you."

"Yes."

Zhang Beixing naturally saw this scene in the surveillance video.

Holy crap! They just start shooting at the drop of a hat?
That damned black cat is truly depraved!

If this continues, the lives of the two elderly professors will be in danger, so we have no choice but to take action.

Plans can't keep up with changes, and upon realizing this, Zhang Beixing immediately cried out in a low voice.

"Everyone, we can't let the biological weapons fall into their hands. Prepare to fire."

Ouyang Qian cried out anxiously, "But my parents are still there!"

"Trust your comrades, and trust your own training."

"Target locked, fire!"

"clear!!"

As soon as the words were spoken, special forces soldiers, who had been lying in ambush in different corners and had already locked onto the enemy through their scopes, arrived.

Almost simultaneously, he pulled the rifle trigger.

——Bang bang bang bang!
Gunfire erupted suddenly, like a storm!

Even the elite K2 fighters, caught completely off guard by this ambush, would not be able to dodge the bullets.

As soon as the gunshot rang out, more than a dozen gunmen were instantly hit in vital areas, convulsed, and fell to the ground dead.

Blood and brain matter splattered everywhere, covering the black cat's face.

The black cat grabbed Zhang Haiyan with a ferocious expression, gritting its teeth.

"Mole! You betrayed me after all!"

"They actually colluded with the military to set a trap for me?"

At the same time, the red blood cells, which were waiting to launch a surprise attack, immediately rushed into the field in a low-profile firing position and engaged in fierce firefights with the K2 elites.

Zhang Beixing pushed his speed to the limit, his figure shooting out like a swift arrow!

He flashed past like a fleeting shadow, a lightning bolt of light streaking across the scene. The two masked thugs guarding the professor and his wife had their necks snapped with a "crack!" and collapsed to the ground, limp and lifeless.

Before the black cat could react and was about to kill the hostages in anger, Zhang Beixing swiftly hoisted the two old professors onto his back and quickly escaped the battlefield.

The two professors were terrified, but thankfully they escaped unharmed.

Ouyang Qian rushed over in a panic to stop her father's bleeding and provide basic first aid.

"Dad! Mom!"

"Qianqian, what are you doing here?"

Upon seeing their daughter appear, the two professors became even more worried.

Zhang Beixing reluctantly interrupted their family's reminiscing.

"We'll talk about it later. It's too dangerous here. Here, take the mosquito coils and leave with your parents first."

“Okay.” Ouyang Qian nodded emphatically. “Mom and Dad, come with me.”

Ouyang Qian and her mother Su Ya helped Ouyang Song, and the three of them quickly retreated out of the research institute, keeping their bodies low.

Gunfire erupted within the research institute.

—Da da da da!
——Bang bang bang bang!
The M4 gun muzzle kept spewing flames, and the special forces soldiers fought back fiercely.

A barrage of sonic blasts was unleashed at once.

Bang!
Om-! !

The special forces soldiers seized the opportunity to quickly advance and open fire. Several masked bandits were shot and fell to the ground, leaving only Black Cat behind.

Seeing the special forces soldiers closing in from all directions, Black Cat angrily raised his M4 rifle and aimed it at Zhang Haiyan.

It felt as if the bullet would be fired at any moment and kill Zhang Haiyan!

Ye Cunxin was shocked to see this scene. She quickly grabbed her sniper rifle and rushed out without a second thought.

Just then, another pistol was pointed at the black cat's head.

"do not move."

The black cat was stunned, turned around in disbelief, and frowned deeply.

"What? Even you betrayed me?"

He Lu sneered as she tore off her mask: "We were never on the same side to begin with."

Seeing that Secretary Yao had suddenly transformed into another person, the black cat stared wide-eyed in disbelief.

What the hell?

Am I dreaming?
The Secretary Yao in front of me is actually a fake!
But her previous appearance was clearly that of Secretary Yao!

How could such a thing happen in the world?
"How is this possible?" the black cat muttered in shock. "Where did she go?"

"Surprised? Don't be!" He Lu coldly rebuked, her face expressionless. "There's even more you can't imagine. Your hundreds of IEDs were already taken care of by our Captain Zhang!"

"Looks like I've met my match." The black cat grinned savagely, its eyes bloodshot. "Female soldier, and who are you?"

"Fire Phoenix!" He Lu roared, no more words were wasted, "Put down your weapons and surrender!"

"Mom, come over here!"

Ye Cunxin rushed forward, her gun pointed at the black cat.

"Lay down your weapons and surrender your arms or you will be spared!"

The black cat saw Ye Cunxin and suddenly gave a cold smile.

Given this situation, even if he had wings, he wouldn't be able to escape it.

He gave Zhang Haiyan a cold look and thought to himself, "Since that's the case, then let's all die together!"
If I die, none of you will have an easy time!
Black Cat turned to look at Ye Cunxin, staring at the black muzzle of the sniper rifle, and spoke slowly.

"Ye Cunxin, don't you want to know who your father is?"

Ye Cunxin was taken aback upon hearing this, and couldn't help but exclaim in surprise, "You know my father?"

Upon hearing Black Cat's words, Zhang Haiyan shouted angrily, "Stay away from her!"

"Hmph." The black cat curled its lips with interest. "Let me tell you my name, my surname is..."

"puff!"

However, at that moment, a gunshot rang out, the muffled sound of the silenced gun echoing for a long time in the research institute.

Before the black cat could utter another word, Zhang Beixing had already decisively fired his gun.

A bloody hole appeared between the black cat's eyebrows, and it collapsed with a thud.

The black cat turned into a dead cat, its eyes wide open in death.

Zhang Beixing slowly lowered the muzzle of his gun, his gaze cold and stern.

"Some secrets are better left as secrets forever..."

The perimeter of the biological research institute, nestled deep in the mountains, is riddled with bullet holes left from the fighting, amidst the broken walls and ruins.

Dozens of armed helicopters hovered low above the research institute, and a large number of armed police officers surrounded the entire building, making it impossible for even flying insects to get through.

Numerous police cars and bomb disposal vehicles surrounded the area. Upon hearing the news, police commander Wen Guoqiang and Captain Gao arrived at the scene wearing bulletproof vests.

Armed police and special police officers were fully armed and on high alert, with their guns pointed at the research institute's gate.

The porch was deserted. Thanks to the all-out efforts of three special forces teams—the Red Cell Special Operations Team, the Thunder Commando Team, and the Fire Phoenix Women's Special Operations Team—not a single member of the K2 terrorist organization managed to escape.

At that moment, Wen Guoqiang's walkie-talkie suddenly rang.

Lei Zhan shouted, "Report! Report! All members of the K2 organization have been captured, and their leader, Black Cat, has been killed on the spot!" (End of Chapter)
