Still hoarding supplies in the apocalypse? I'll just go on a killing spree and looting!

Lin You held the tactical light to her chest, gripped the steel cable with both hands, and braced her toes on the fixed nodes of the cable.

"Go up from here." She climbed up a few steps, her movements swift and efficient.

Mu Xue swallowed hard, put the shotgun into her personal storage space, and grabbed the steel cable like Lin You did.

The steel cable was cooler and slipperier than I had imagined.

"Don't look down. Grab upwards with your hands, and hold onto the cable with your feet. Move only one limb at a time," Lin You's voice came from above.

Mu Xue took a deep breath; this was the first time she had ever gone upstairs this way.

Grasping the cold cable, Mu Xue began to climb.

She moved very slowly, pausing after each step to make sure she had a firm grip.

The cable swayed slightly in her hand, and she could hear her own heartbeat.

As for technician Lin Tanzhi, he actually did a better job than her.

He followed closely behind Mu Xue, even having a little extra strength to push her feet so she wouldn't slip.

Lin Tanzhi's actions made Mu Xue grit her teeth and climb upwards with all her might.

She can't be worse than an ordinary person.

Lin You arrived at the fourth floor first.

She gripped the elevator door rail with one hand, her legs dangling from the cable like a python, while her other hand shoved a bone knife into the door crack.

They successfully pried open the elevator door and pulled it open to both sides.

Light streamed in from the corridor, cutting the darkness of the elevator shaft in two.

She climbed out of the elevator, squatted on the corridor floor, and pulled out the mantis knife.

The corridor on the fourth floor is different from that on the third floor.

It's cleaner here; there's no broken glass on the floor, and the bulletin boards on the walls are intact.

At the end of the corridor, a roadblock was set up with lab tables and bookshelves, and a figure was moving behind the roadblock.

There are people there.

Mu Xue climbed out of the elevator shaft, kneeling on the ground panting, her forehead covered in sweat. "Next time, let's take the stairs."

"You'll get used to it." Lin You stood up and made a gesture to wait for silence.

He sheathed the mantis knife and drew a pistol from the holster on his thigh.

When dealing with people, a pistol is far more intimidating than a knife.

Lin You walked casually to a spot three meters in front of the roadblock and stopped, glancing inside.

A spear made from a mop was placed on the roadblock, and a person was sitting on a chair next to the spear.

Lin You couldn't help but smile. "Xia Lin, wake up."

There was silence for a few seconds behind the roadblock.

Then a familiar, low murmur rang out, tinged with uncertainty and disbelief: "Am I dreaming?"

"I don't think so."

Charlene suddenly stood up from her chair, holding a fire axe in her hand, and immediately turned around.

Then she saw Lin You standing behind her.

Charlene had lost a lot of weight, and her cheekbones were more prominent than when she was camping in the mountains, but her eyes were still the same.

When she saw Lin You's bald head clearly, her eyes suddenly reddened.

"You're alive." Her voice trembled, not from fear, but from some emotion that had been suppressed for two days and two nights and could finally be released.

Charlene's voice was a little loud, and a door on one side was opened.

Wang Tao peeked out from the door and his eyes widened immediately when he saw Lin You.

"Sister Lin...?!"

His tone was full of surprise and disbelief.

Wang Tao's face was very pale, and his left shoulder was bandaged with pale yellow medicine stains seeping through it.

Mu Xue had already pulled Lin Tanzhi, who was still in the elevator shaft, up and looked at the boy who had spoken.

After confirming this point, Sister Lin seemed to know them and pulled Lin Tanzhi forcefully again.

Meanwhile, Lin You, in the hall, carefully observed Wang Tao.

His windbreaker sleeve was torn in half, revealing the muscular muscles underneath.

Qin Ying also peeked out from the other side of the roadblock, holding a piece of iron with one side of its blade cut open.

The three people stared blankly at Lin You, who had suddenly appeared.

"What are you doing here?" Lin You inserted the pistol into the holster on her thigh.

Charlene put down the fire axe and wiped her eyes with the back of her hand. "That day on the mountain, you told us to go back to the city. So we went back to school, and then the gray fog appeared. The whole school was full of man-eating monsters."

As she spoke, Charlene couldn't help but shudder.

It seems that what happened that day left her with psychological trauma.

Lin You looked at Qin Ying, the bespectacled boy whose emotions were much more stable than Xia Lin's.

Qin Ying explained, "Later we met Professor Shen—he was in charge of this laboratory building and brought us here."

"Hmm? Professor Shen Mu?" Mu Xue walked over at some point, holding a shotgun and asking curiously.

"Do you know Professor Shen?"

"Yes, he's my professor. In a way, I'm your senior."

The three of them were slightly taken aback, but then greeted each other in unison, "Hello, senior."

Mu Xue smiled at the three of them, nodded, and asked, "Where is Professor Shen?"

Charlene looked sad. "Professor Shen is injured, and An Yan is taking care of him."

"What happened?"

"The day before yesterday, Professor Shen went to the convenience store across the street to find some food. He encountered a monster and that's how he injured his hand."

"That terrifying beast downstairs?"

"That's the monster. Brother Qin hit it with a steel frame, and then it was killed with an axe."

Mu Xue became anxious and pressed for an answer, "Then...where is Professor Shen?"

"It's in the room inside." Xia Lin pointed to the room Wang Tao came out of, her face showing a worried expression.

Mu Xue nodded to Lin You and couldn't wait to look at Professor Shen.

Wang Tao glanced at Xia Lin and said, "I'll go take a look." Then he followed Mu Xue into the room.

Lin You looked at Xia Lin and Qin Ying and asked, "Why don't you go out?"

Charlene asked blankly, "Go out? Where will we go after we go out? There are monsters everywhere."

Qin Ying sighed and said, "We can't get out. We've blocked the staircase between the third and fourth floors. The elevator is the only way out, but it's out of power. We made a makeshift pulley out of rope in the elevator shaft, and we were planning to go down today. But Professor Shen said there's something in the underground parking lot—he said that on the day the gray fog descended, several monsters chased students into the parking lot and never came out again. Professor Shen also encountered those monsters on the first floor."

Wang Tao added, "Going down the elevator shaft is too dangerous. So we just kept waiting."

"You've waited for us," Lin You said. She looked at the door of the laboratory behind the roadblock, with a faded label on it that read "Molecular Biology Laboratory."

This was exactly the place she was looking for.

Lin You pushed open the laboratory door.

The equipment inside was more complete than expected—centrifuges, PCR instruments, electrophoresis tanks, and clean benches were neatly arranged on the lab bench.

Each device has a label indicating the instructions for use and calibration parameters.

Of course, there can't be just one of these instruments.

This is a university, and its main purpose is to teach students how to use it. How can you recruit students using just one machine?

In the reagent cabinet against the wall, glassware is arranged by specifications, and the labels on the reagent bottles are written in marker: "For antibacterial experiments only" and "Do not touch".

There was a makeshift bed made from a laboratory table in the corner.

An elderly man with gray hair lay on it, his face flushed and his breathing labored.

He made a simple bandage on his left leg with strips of cloth torn from his lab coat. The cloth was stained with dark red blood, and the surrounding skin was red, swollen, and inflamed.

Xia Lin squatted down next to the old man and softly called out, "Professor Shen."

Professor Shen did not respond; his lips were chapped, and he occasionally uttered incoherent murmurs.

Charlene looked up at Lin You, her face full of worry. "Professor Shen has broken his leg, and the wound is infected. He has a persistent high fever. We don't have antibiotics, only strips of cloth and cold water."

Lin You walked to the bedside and touched Professor Shen's forehead with the back of her hand.

It's very hot.
