At this moment, in the dim and silent research room, a faint beam of light stubbornly pierced through the gap in the half-drawn curtains, barely illuminating the scene inside.

To avoid attracting the attention of the zombies, Professor Chen covered the windows even though he knew it was pointless.

At least we can't see the zombies outside, which is some psychological comfort.

At this moment, Professor Chen's face was pale and bloodless, and fine beads of sweat on his forehead glistened in the dim light, revealing his inner anxiety.

He was surrounded by four equally haggard researchers, their figures appearing particularly lonely and helpless in the cramped space.

Like Xiao Guo, Shi Lei was not only a colleague, but also a prized student of Professor Chen.

He moved closer to Professor Chen and asked softly, "Professor, will we really be able to wait for rescue?"

Professor Chen was actually a little apprehensive, but he was, after all, a teacher, the pillar of support. Everyone else could be pessimistic, but he couldn't.

If that's the case, the team will fall apart.

He scolded Shi Lei: "Of course you can, don't overthink it."

"The country is in peril right now. What are we? We are researchers. The zombie virus still needs us to conquer it. The country will not abandon us!"

We will not abandon the vaccines, nor will we abandon them.

Shi Lei clenched his fists, persistently repeating, "Yes, the rescue team will definitely come. Teacher, you're an expert in bacteria and viruses, they'll come..."

This is the only thought keeping Shi Lei and the others hanging on; otherwise, they would have given up long ago.

If you look closely, these five people are in extremely poor condition right now.

Their clothes were wrinkled and had long lost their former neatness and dignity.

His hair was a mess, like straw, his stubble grew wildly on his face, and he exuded an indescribable foul odor.

Recalling the first day of the apocalypse, the research institute suddenly fell, and civilization and order collapsed in an instant.

They had no choice but to flee into the laboratory on the 12th floor.

However, their haste to escape left them no time to take any food or water, except for the experimental data that were as precious to them as life itself.

For two days, a full seventy-two hours, they have been enduring the hardships in this cold laboratory.

Hunger is like an invisible hand, constantly tearing at their will. They have only managed to hold on thanks to the tap water.

Just then, Professor Chen and the others felt a violent commotion that pierced through the heavy metal door and struck their eardrums.

The sound, mixed with the unique roars of zombies, made one's heart involuntarily clench.

Two days ago, due to a moment of carelessness, they accidentally led a group of zombies into this research area during their relocation.

From then on, as if they were certain there were living people here and refused to give up, the zombies refused to leave and roared at the door day and night.

Even so, the noise outside is now far beyond what it used to be.

No, that's not right!

Did something unexpected happen?

Seemingly realizing something, Professor Chen and the other four exchanged glances, all understanding each other's thoughts.

Someone must be coming!

Realizing this, the group became extremely excited and rushed to the main entrance, pressing their ears against it...

On the other side of this chaos.

Xiao Jin stood in the shadows on the other side of the corridor, his gaze sharp and cold, with Wan Sha and Pan Lizhi behind him.

To her, the number of zombies didn't matter. She didn't care about luring them away; she just charged in.

Since you have overwhelming strength, then stop wasting time.

Therefore, when Wan Sha and Pan Lizhi wanted to determine the tactics, Xiao Jin calmly said, "No need for that..."

With enough space, she brandished her shattered shadow and looked up: "Just kill them all!"

Pan Lizhi and the other two looked astonished, seemingly not expecting Xiao Jin to say such a thing.

"No, this is too dangerous. There are a lot of zombies ahead. You... Eh??" Before Wan Sha could finish speaking, Xiao Jin rushed out.

Like a ghost in the dark, Xiao Jin didn't even need to teleport. After a short run-up, she arrived in front of the zombie horde and launched a deadly attack.

Seeing this, Wan Sha gritted her teeth, but still ran over with Pan Lizhi.

Lu Jiawei, who was inside the pipe above, almost burst into laughter when he saw this.

Yes, that's how you fight, go quickly!

But then he was the one who was dumbfounded.

The movements were swift and precise; each swing of the knife was accompanied by the heavy sound of a zombie falling.

Even a level 2 zombie couldn't withstand a single blow from Xiao Jin and was instantly cleaved in two.

Although Pan Lizhi and Wan Sha were a step behind, they quickly regained their rhythm after the initial shock and began hunting zombies.

While killing Pan Lizhi, he couldn't help but think to himself: This Lu Jiawei is such an idiot. Why did you provoke such a ruthless person?

In less than five minutes, the zombies in the corridor were wiped out.

Xiao Guo was overjoyed, and Liu Chong and the other superpowered individuals looked at Xiao Jin with admiration, while Lu Jiawei felt a chill in his heart and even began to despair.

If you go against this monster, won't you end up dying yourself?

"Quickly, Professor... We must find the Professor immediately!" Xiao Guo's voice was filled with an undeniable urgency.

With the threat of the zombie horde eliminated, Xiao Guo could no longer contain his anxiety.

Like a butterfly eager to emerge from its cocoon, he leaped out of the narrow pipe, landing firmly on his feet, with the rest of the people following closely behind.

As they passed by the gruesome remains of zombies on the ground, they instinctively tiptoed, trying to avoid touching the nauseating fragments. An indescribable stench and tension filled the air.

"How do I open this door?" Liu Chong's voice suddenly rang out in the empty corridor as they reached the doorway.

With a hint of doubt, he turned to look at Xiao Guo.

Xiao Guo didn't answer immediately. He rummaged in his pocket for a while, and after touching something, a smile appeared on his face.

"Don't worry, the lab's power system is not damaged, which means our access control system is still working."

As he spoke, he pulled a thin electronic card from his pocket, the card gleaming with a cold metallic luster in the dim light.

Xiao Jin glanced at it and clearly saw that Guo's photo was printed on it, along with several large black characters—A-level researcher Guo Lin.

"Only by swiping a card and recording pupil information can the door be unlocked."

Xiao Guo gently placed the electronic card on a sensor area on the wall. At that moment, the air seemed to freeze, and everyone's eyes were focused on the small card.
