One important reason why zombies are so difficult to deal with is that they have a certain characteristic.
Like locusts in nature, they exhibit a swarming effect.
In nature, if there are only a few or dozens of locusts together, you can even catch them and fry them to eat.
However, once a locust plague occurs, the level of danger increases exponentially.
Xu Xing often heard people say, "Why don't we catch and eat the locusts during the locust plague?"
The reason is that once locusts gather in large numbers, they secrete a toxic substance that makes them impossible to consume in large quantities.
The same applies to zombies. Once they form a large-scale gathering, although they may not produce toxins, they can still emit a kind of aura.
This allows one or more zombies to evolve rapidly, which is the direct reason why zombies always evolve faster than humans.
Xu Xing explained the dangers to Su Xixi, which made the originally calm Su Xixi feel a sense of crisis.
To better understand the situation, Xu Xing climbed alone to the highest point of Su Xixi's house, which was also the highest point in this villa area.
He retrieved a military telescope from inside the space and began observing westward.
Xu Xing was shocked when he saw it.
From observation, there are no living people left in the school; all the students have turned into zombies.
Whether on the playground or between the dormitories, zombies were everywhere.
Most of the school grounds were covered with dark red stains, likely bloodstains left from when the zombie outbreak first occurred.
Xu Xing also saw a middle-aged, bald zombie wearing a suit on the school's rooftop.
His height was nearly two meters, and there was no significant decay on any part of his body.
Xu Xing guessed that this was probably the source of the sound last night, and it was indeed from this school.
Judging from its appearance, it is most likely one of the school's principals. Considering the degree of decay of its body, a more accurate estimate is that this zombie is probably at the late stage of level three.
Given that Xu Xing is currently facing a direct attack, he is unlikely to defeat this zombie. Moreover, since it is in the school, he may not even get close to it, and is more likely to be overwhelmed by other zombies.
On the other hand, it's fortunate that this school is a closed educational institution, surrounded by walls, and the hotel entrance is also very tightly enclosed.
Although this resulted in everyone in the school becoming infected.
But at least it couldn't spread out, and since the population around the school wasn't dense, the zombies didn't have the strong desire to rush out together.
The only concern is that late-stage level 3 zombie. Once it completes its evolution and enters the late stage, it might integrate these scattered zombies.
This put Xu Xing in a dilemma again. He couldn't defeat it in a fight, and as it continued to evolve, it would eventually devour him.
However, they cannot relocate. Apart from the school, Xu Xing had been planning to choose this place for a long time. If they changed locations, the situation might be completely different.
