Tang Xiaoquan pondered for a long while, but couldn't find a solution to his worries, so he simply chose to give up. Everything would have to wait until he was out of this damn quarantine room to find a breakthrough.

After another bout of random thoughts, Tang Xiaoquan remembered that he still had a notebook with him. He called a guard over and retrieved a ballpoint pen, then returned to his seat.

Another almost two weeks of post-apocalyptic life had passed, and in that time, Tang Xiaoquan's experiences were nothing short of extraordinary.

From the near-death investigation at the bottom of the building, to his first meticulously thrilling creation; from Wei Yang father and daughter's separation by death; to Old Zhao's unwavering commitment.

The word "humanity" added several new perspectives to Tang Xiaoquan's heart.

Perhaps humans are inherently selfish; we hunt animals for delicious food, harm companions for personal gain, and even curse over trivial matters.

But it cannot be denied that even in the apocalypse, no matter how dire it becomes, good people still exist, such as Wei Yang and Old Zhao;

And perhaps their qualities are the hope for rebuilding human civilization.

Hopefully, in the end, everyone can still hold onto this unchanged intention!

At this point, Tang Xiaoquan's right hand holding the pen paused slightly, because he knew how great a test this wish would endure. Even he dared not deny whether one day in the future, he might do something against his conscience and morals for resources or for his brothers around him.

After sighing, Tang Xiaoquan slightly adjusted his mindset, and as usual, prepared to record what he had gained from recent encounters with zombies.

First, fire!

Zombies are not afraid of fire, this is undeniable, although fire can indeed cause damage to zombies and can turn them to ash.

But in terms of practical effect, Tang Xiaoquan would never consider fire as a weapon to attack zombies.

There are two reasons:

One, efficiency is low.

It is well-known that the strength of zombies lies in their ability to assimilate. In other words, as long as you haven't killed them, they always have the potential to turn you into one of them.

To avoid such events, the efficiency of killing zombies is naturally an extremely important aspect.

But obviously, flames do not have such characteristics.

Not only that, if you really light a zombie during battle, then waiting for you is not just assimilation and mutation.

"Playing with fire" might become your final fate.

Two, it's too eye-catching.

Without considering whether fire can kill zombies, even if it could, the moment the flames ignite, you would have to pray your legs are fast enough. Otherwise, you would quickly find yourself surrounded, chased, and intercepted by endless hordes drawn by the fire.

Having written this point, Tang Xiaoquan wiped the sweat beading on his forehead. Truth be told, summarizing and concluding in such a stifling environment was indeed a test of one's will.

Fortunately, Tang Xiaoquan had decent patience. Years of being a homebody had long taught him to endure the loneliness of solitude.

After calming himself slightly, Tang Xiaoquan once again delved into his thoughts.

This time, however, he didn't rush to write, instead furrowing his brow as if contemplating something critically important.

Moments later, his right hand, which had hovered in place for quite a while, finally dropped down and without hesitation, he wrote three strong characters:

Runner!

Runner: As the name implies, a messenger that runs. But in this post-apocalyptic world, no doubt, this messenger's title must bear the word "Hell."

Indeed, Tang Xiaoquan classified those zombies on the highway that had begun to exhibit running abilities as "Hell Messengers" capable of running.

As for the rest who still staggered and dragged their steps like novice zombies, he categorized them into another type called "Pacer."

"Runner, Pac...er?"

The low rumbling voice came to his ears. When Tang Xiaoquan turned his head, he saw Hu Xiaodong's sculpture-like face full of puzzlement looking at him.

"What are you writing?" Hu Xiaodong asked directly, voicing his inner question.

"Uh~" Scratching his head, Tang Xiaoquan was a bit at a loss, clearly feeling somewhat embarrassed at having his writings seen. He hesitantly explained, "I, I'm classifying the zombies we've encountered..."

Seemingly trying to find a more reliable term to express his thoughts, after a moment of hesitation, Tang Xiaoquan resolutely added, "Hierarchy! Yes, I'm classifying the hierarchy of zombies!"

"Hierarchy!?" With these words, it was undeniably surprising, and everyone exchanged glances, not knowing what Tang Xiaoquan was up to.

And Wen Quanxin, who loved gaming, couldn't help but jokingly tease, "Qiangzi, you must be so bored without games that you went nuts!"

"Damn! This dude? Playing games?" As if recalling some unpleasant past event, Wang Qiang pursed his lips and lamented painfully, "If any of you ever have the chance to team up with this guy in a game someday, then you'll truly understand the phrase 'teammate like a pig'!"

Hahaha...

Amid the bouts of laughter, peers like Wu Chao and Acheng shared knowing expressions.

After the young ones finished their amusement, Hu Xiaodong pretended to cough to draw attention, then placed a reassuring hand on Tang Xiaoquan's shoulder.

Undoubtedly, he wasn't going to believe the young man before him was engaging in such nonsensical fantasies, so he got to the point, "Xiao Tang, tell us, what do these... uh~ 'hierarchies' mean!"

Feeling rather awkward, Tang Xiaoquan glanced at Hu Xiaodong, not intending to share his classifications with everyone.

It wasn't because he was stingy, but... he felt that if he explained it too detailedly, it might be laughed at as childish.

But his big brother spoke, so he couldn't refuse!

Wang Qiang still maintained a "gloating" expression beside them. Helpless, Tang Xiaoquan could only smile bitterly to himself and then began his explanation with patience.

He openly explained why he thought of classifying the zombies into hierarchies and interpreted in detail what pacers and runners meant, not forgetting to express his concerns and worries.

After he finished speaking, there was utter silence. Even Wang Qiang, who was waiting to see a joke, was now solemnly pursing his lips.

Without a doubt, Tang Xiaoquan's words just now were striking, and for the first time, the survivors realized the severity of the situation.

"Adaptation," "Pacer," "Evolution," "Runner," these plain words summarized by the young man kept stirring each survivor's heart.

If zombies could really evolve due to "adaptation"... then...
