"Brother, what's wrong?"

Sun Muchen suddenly noticed that Wang Lan's body was swaying slightly, and couldn't help but ask.

Wang Lan, holding onto the side of the elevator, said, "I... feel a little dizzy."

"It's probably the feeling of weightlessness caused by the elevator going down," Lao Zhang explained. "After all, it's my first time riding an elevator, so it's reasonable to feel a little dizzy."

Wang Lan glanced at Lao Zhang, wanting to say something, but the elevator seemed to speed up, making Wang Lan feel like vomiting. He pressed himself against the elevator, when suddenly the elevator shook violently with a loud "bang bang bang". Wang Lan was so frightened that his eyes widened, and he was about to pull out the Vajra Umbrella.

Old Zhang said, "We've arrived."

Wang Lan was taken aback. "Huh? We've arrived? What's arrived?"

The elevator has stopped.

A "ding-dong" sound.

The door slowly opened.

Wang Lan finally breathed a sigh of relief, but before he could exhale completely, an infected person wearing a white coat pushed the elevator door, which was not fully open, to both sides. The huge mouth on his hideous face seemed to be torn open, and he suddenly shoved it in.

Holy crap!

This scene terrified the three people in the elevator. Wang Lan immediately kicked the infected person out, and Lao Zhang reacted quickly, raising his machine gun and firing a barrage of shots at the head of the infected person lying on the ground, smashing the head beyond recognition.

But the gunshots brought the brother and sister back to their senses. They followed Lao Zhang out of the elevator, and before they could even look around, they heard the roars of the infected.

Sun Muchen instinctively threw a gun to Wang Lan, and then the three of them raised their guns, aimed at the infected people rushing towards them, and fired.

The room didn't look very big, so the infected person wasn't far away from them, which meant that all the bullets fired by the three of them landed on the infected person's head.

Gunshots rang out incessantly, but the shouts of the infected were becoming less and less frequent. This not-so-small number of infected was quickly wiped out by the three men.

When the last infected person died, their gun barrels were already scorching hot.

Old Zhang casually picked up a piece of clothing next to him and tossed it to Wang Lan, saying, "Put on some clothes. Even though clothes don't offer much protection, at least they'll give you some peace of mind."

Wang Lan then remembered that she had given her clothes to the two of them as face masks.

So he put it on without any hesitation.

Only then did they carefully look around.

All of these deceased infected individuals were wearing white coats, and they all seemed to be technical researchers. Wang Lan walked over to several infected individuals and examined them, discovering that they were all wearing name tags on their chests, but the tags were stained with blood and could not be read.

The infected people's deaths were gruesome, and Sun Muchen didn't want to look at them, so he began to observe his surroundings.

This place appears to be a laboratory, with numerous workbenches filled with various experimental equipment and a jumble of unidentifiable devices, all lying haphazardly on the ground.

One wall of the laboratory was covered with various bottles and jars. Sun Muchen walked over in confusion, only to find that the bottles and jars were marked with all sorts of obscure chemical symbols. This stumped Sun Muchen. She looked at them one by one and found that she could not name any of them. She could only keep looking at them. Then, she suddenly noticed that there was an irregular piece of tofu soaking in one of the bottles and jars.

At first, Sun Muchen didn't realize it was a white object covered in patterns. But when she realized it was a brain, she turned pale with fright, screamed, and jumped up.

Wang Lan quickly moved to Sun Muchen's side and asked, "What's wrong?"

Sun Muchen adjusted his breathing, raised his head and pointed to the bottles and jars. Wang Lan followed his gaze, but was also stunned.

These bottles and jars were filled with various human tissues, including the heart, liver, spleen, lungs, kidneys, and brain.

As you walk along the bottles and jars on the wall, the more you walk, the more bizarre the contents become. From simple organs and tissues, they gradually transform into dried chunks of meat, vertebrae split into several segments, and fleshy balls made up of countless empty eyes.

In short, each one is more abnormal than the last.

Wang Lan couldn't stand it anymore either.

The brother and sister turned their backs to the wall, swallowed, and then looked elsewhere.

Besides this wall, the laboratory also has a staircase leading to the second floor. The other walls are mostly occupied by metal doors, each with a window, but the inside is pitch black and cannot be seen clearly.

Above the laboratory, there are crisscrossing thick metal sections, seemingly there to support the weight of the glass above.

Wang Lan picked up a strange blueprint from an experimental table. The blueprint was very large, especially the buildings drawn on it. It took Wang Lan a long time to finally understand it.

This is…

The final fortress's structural diagram!

Wang Lan was stunned.

Although many parts are covered by bloodstains, it is not hard to see that the exposed egg-shaped building is only a small part, or even just the tip of the iceberg.

The first floor was indeed the residential area, but it was far more than what the group had seen. It consisted of multiple areas, including a simulated city, a planting area, and an entertainment area.

The second layer, the core area of ​​the fortress, is the most crucial part for maintaining the normal operation of the entire final fortress. It is where energy is supplied, converted, and transmitted, and the fortress's external defenses can only be released through this area.
