In the apocalypse, I have a flying house with unlimited upgrades.

Xu Shuai believes that the most significant danger at present is still zombies, and the emergence of special combat suits can greatly prevent zombie attacks.

Special operations uniforms are made of special materials, containing tungsten metal, which has extremely high ductility and impact resistance, while also providing protection against scratches and stabs.

Upon first wear, it will automatically adjust to the user's body size for comfort.

Optical reflection, as explained, refers to the way the color of special operations uniforms changes in different environments, similar to a chameleon, thus achieving optical 'stealth'.

Self-repair refers to the process where, after a certain degree of wear and tear on special operations uniforms, the protective capabilities decrease and the metal activity becomes insufficient, requiring metal repair.

In summary, special operations suits can greatly ensure the continued development of the flying house.

The test results are now available. Xu Shuai threw the zombie's left leg into a dark corner, closed the window, and opened the door.

The next focus will be on observing the recovery of various parts of the elderly zombie's body before heading to the city.

"They're leaving already? Aren't they going to observe it further? Like, chop it into minced meat and see if it can recover?"

Despite Ye Ziming's persistent questioning, he continued to leave quickly, staying right beside Xu Shuai.

The exhilarating destruction creates a wonderful sense of relief for the brain. Ye Ziming found himself trapped in this strange "comfort zone" after the apocalypse began.

Now, besides eating and sleeping, he is most interested in two things: looting in the field and fighting zombies.

"Once you enter the city, there will be plenty of zombies for you to fight. With such a large population, even if the initial mutation rate is only 5%, the number of zombies generated will reach a terrifying number as one person spreads to ten, and ten to a hundred," Xu Shuai said in a gloomy tone.

He kept thinking about this on his way to other rooms to check on the changes in the zombies' bodies.

Given the current combat capabilities of the zombies, the authorities could have started clearing and rescue operations within 24 hours of the apocalypse's outbreak. Why wait until half a month later?

Could it be that the zombies at this stage are not strong enough and need some time to evolve further?

Could it be that the evolution of zombies will produce some benefits, thus achieving an effect where the advantages outweigh the disadvantages?

Upon realizing this, Xu Shuai's mind cleared, and in a sudden instant, he seemed to have understood something.

The fleeting sense of clarity was not fully grasped at the time; once the train of thought was broken, it was extremely difficult to understand it later.

Before long, the three arrived at the room containing the zombie's right leg. After observing it, they found that the right leg's recovery ability was almost the same as that of the left leg.

After Xu Shuai had Ye Ziming knock out the blood hidden inside the zombie's right leg with a stick, he threw the limp right leg into a dark place, and the three of them hurriedly went to the other rooms.

The zombie's arms recovered at a similar rate to its lower limbs, but the recovery of its torso was the worst. When Xu Shuai opened the door, dark green blood was still seeping out from the five gashes.

"Old Xu, how do we do this?" Ye Ziming, who had been following Xu Shuai all along, started to think more carefully before doing anything.

"Just disrupt its recovery process by kicking it into a shaded area. The same applies to the torso and limbs. Knowing its recovery speed is enough; it's not very useful for reference," Xu Shuai replied approvingly.

Right now, the focus is on the zombie's head. After Ye Ziming interrupted the body's recovery process, the three of them went to the room where Xu Shuai had previously kept the zombie's head.

Even before anyone got close, a faint rubbing sound could be heard, as if it were calling out, "Help me, help me..."

The three were on high alert. Xu Shuai and Ye Ziming worked together to receive the first wave of attacks, while Su Mo was responsible for guarding the rear and the surrounding area.

Xu Shuai opened the door, kicked out, then dodged and pressed himself against the wall, while Ye Ziming held up his shield to block the doorway.

At this moment, Ye Ziming, who was on high alert and carefully dealing with the situation, saw what was happening in front of him and exclaimed, "Holy crap, Lao Xu, the zombie head has grown legs!"

How is that possible? A zombie head can grow legs? You must be seeing things.

Xu Shuai turned to face the doorway, and out of the corner of his left eye, he caught a glimpse of a rapidly moving green figure. He blurted out, "Ye Zi, raise your shield!"

A crisp sound of shattering glass rang in my ears, crashing and shattering...

It wasn't an attack, it was an escape? Xu Shuai, realizing what was happening, patted Ye Ziming on the shoulder, and the two rushed into the room one after the other, quickly closing in and standing side by side.

After scanning their surroundings and making sure no corner was missed, the two moved quickly toward the windowsill once they were sure it was safe.

My gaze followed the rapidly moving object below. It was a tall, humanoid figure, over two meters tall, with an extremely robust build. Its head was lush and green, as if it were wearing a green bonsai. It held a dark, unsightly object in its right hand and, with the gait of a gorilla, quickly climbed the wall in two strides, before disappearing at the end of the road.

"Holy crap, Lao Xu, did you see that clearly just now? What was that thing? It even knew how to run away. How did it get down there?"

Ye Ziming scratched his head, feeling somewhat curious about this mysterious species.

In just a few seconds, the mysterious object descended to the ground, revealing a five-story villa nearly twenty meters tall.

If they were to jump directly down, based on the physiques they observed, their weight would be at least over 100 kilograms.

Even if we don't consider whether its limbs can withstand such a huge impact, at the very least, there will be a crater in the ground, or some signs of a fall.

But the area below is completely clean, which is rather strange.

Xu Shuai withdrew his gaze, braced his hands under the balcony railing, leaned out, and surveyed his surroundings.

Finally, a clue was found on the water pipe nearby: spots of green, which were probably bloodstains from the old man's zombie head.

Following the trail of clues, Xu Shuai finally came to a startling conclusion.

That guy actually grabbed onto the water pipe and slid down. His movements were clumsy, and his weight was too great, causing him to descend too fast. When he landed, his legs made two uneven dents on the marble floor.

With that physique, why bother running? He could kick a riot shield apart with one kick. It seems like the roles of the two sides have been reversed.

Could it be that this thing possesses some level of cognitive ability, and instinctively fled when it couldn't understand its own strength?

Thinking of this, Xu Shuai felt increasingly heavy-hearted; this was not a good discovery.

Physically, this is not an ordinary zombie. When an ordinary zombie transforms from a human, its limbs will atrophy to varying degrees, as if it is compressing and squeezing out excess impurities in its body, thus making its body more agile.

This zombie felt distinctly different. Its physique was unlike that of a normal zombie, and it no longer blindly followed its bodily instincts. It possessed a certain degree of self-awareness and could even engage in simple thinking.

Just then, Yang Kexin's voice came through the earpiece: "Xu Shuai, something's wrong! A convoy of vehicles with unknown origins is heading up the mountain!"
