Nanhai Medical University.
Half a month after the apocalypse broke out, it had completely become a paradise for zombies.
At this moment, on the fifth floor of the experimental building, three people were slumped in the animal laboratory.
They were one male and two females. One of the females looked to be in her late forties, wearing black-rimmed glasses, clearly a teacher, and the other two were naturally students.
When the zombie outbreak occurred, they had just finished class but were forced to flee back here before they could even leave the experimental building.
There was no communication, no way to call for help, and the outside was full of zombies.
The desperate trio had barely survived by relying on some low-quality corn, wheat, and other animal feed in the laboratory.
However, laboratories did not store much feed, and the food consumption of the three people over half a month was also enormous.
Even though they ate only a little each time, sometimes only one meal a day, they had still exhausted all the food in the laboratory by yesterday.
Not even the edible small animals were spared.
"Teacher, why can animals mutate, but we humans can't..."
"If only humans could mutate too, then we could fight our way out and find food ourselves."
The young female student, wearing a white lab coat, squatted on the ground and complained in a weak voice.
The middle-aged female teacher could not help but sigh, "Perhaps it's not that humans can't mutate, but that we few don't have that luck."
"In essence, aren't humans also animals? In fact, ever since I saw that mutated rat, I've always felt that humans can mutate too, it's just that certain conditions might need to be met."
A week ago, the three of them had personally seen a rat as large as a calf appear downstairs, and it had even gnawed on a few zombies before leaving.
The rat was pure white, and it should have been a lab white rat.
Initially, the three thought it was a zombie rat, but after the female teacher observed it carefully, she discovered that the mutated white rat actually possessed intelligence!
Even when it was eating zombies, it remained extremely vigilant, completely different from the living dead zombies.
The appearance of the mutated white rat gave the three of them hope. The female teacher suggested holding on for a while longer, perhaps one of them could mutate and evolve.
However, another week passed, and even until today, there had been no sign of evolution.
Although the female teacher still believed that humans could evolve, unfortunately, she did not seem to see that day coming.
Because with their physical condition, it was uncertain if they could survive until tomorrow, let alone evolve.
The female teacher, whose physical functions had declined with age, was now feeling a bit dizzy and might pass out from hunger tonight.
In a daze, she seemed to hear the roars of zombies again, as if returning to the day the apocalypse broke out.
It was like that day...
"Huh? Did you hear something?"
The male student, who had been silent all along, suddenly spoke.
"Isn't it just the roars of zombies? What's so strange... Huh? Why are there human shouts too?!"
The female student immediately stood up from the ground, but almost fell due to low blood sugar.
The female teacher also snapped back to reality, realizing she hadn't been hallucinating.
She and the male student hurried to the window, but...
They had forgotten that this window faced the back of the experimental building, while the source of the sound was clearly from the front.
So, all they could see now was the school wall not far away, and nothing else.
They could only guess the situation outside by listening to the mixed sounds.
"Teacher, are those fighting sounds?" the male student asked uncertainly.
"I seem to have heard them too, but..."
"It really is! Does that mean someone is coming to rescue us?!" the female student interrupted before the female teacher could finish.
The female teacher shook her head, "The sounds are very faint, it's not necessarily a rescue, it could also be people escaping."
"Ah?" The female student scratched her head. She hadn't washed her hair in half a month, so it was very itchy. "But that's unlikely, isn't it? It's been half a month, who still has the strength to escape? I'm afraid of getting dizzy even when walking now..."
The female teacher nodded and sighed slightly, "Let's hope they are coming to save us..."
"..."
The three of them sat back on the ground, falling into silence.
