Everyone was stunned by her words, after all, the classmates in the first class had just experienced the accident at the zombie domestication base, and they didn't want to encounter any scenes of being bitten by zombies again.

"You don't really think these dead things are going to bite, do you?" Mao Yun laughed and quipped, "It's really a flower bone that hasn't gone through wind and rain." ”

Su Yu frowned when he saw Hao Tian, and he didn't seem to be very satisfied with Mao Yun's joke.

But most of the students were relieved.

Mao Yun smiled and waved his hand to beckon everyone to get on the elevator.

With the "ding" of the elevator door, the specimen dissection room on the basement floor arrived.

Su Yu stood behind Hao Tian and crossed her shoulder to see a long passage, with a large iron door on each side of the passage.

"Come, flowers, follow me." Mao Yun brushed open the big iron door on the left hand side with her hand screen, and Su Yu and Hao Tian followed behind her.

Su Yu saw that the iron door opened automatically, and the width was actually one meter thick, and there was a "bang", giving people a sense of metal heaviness, and he couldn't help but be a little puzzled.

"This door is almost at the door of the bank vault, these specimens are so precious? This is a precautionary matter. Hao Tian touched Su Yu's arm and whispered.

This is also Su Yu's question, since they are all dead things, and they won't run away with long legs, what is it preventing? She looked back at the other large iron door on the other side, which seemed to be thicker and stronger than the one on this side, but on the surface it appeared to have more than one layer of dongle locks. She leaned closer to Hao Tian: "Why are you mysterious everywhere, look at the door on the right." ”

Hao Tian looked back: "Yes, is it also a specimen room?" ”

Mao Yun, who was walking in front, suddenly turned around, and looking at her expression, she should have heard the conversation between Su Yu and Hao Tian. She smiled slightly and raised her hand screen, and said to the two of them, "I don't know what's in there, and I don't have permission to go in." ”

"Alright, let's get back to today's lesson."

Mao Yun turned around and turned on the lighting in the specimen room with a hand screen. All of a sudden, the spotlights in the entire specimen room were turned on, and each specimen displayed inside had a different spotlight illuminating the main part from an angle suitable for observation, so that people could instantly distinguish where the focus of viewing was.

The specimens are all covered by thick transparent glass, and most of them are waist-high, so that people can see what is displayed inside when they look down.

"Look here, this is the brain specimen of the zombie, which is what I want to show you today." Mao Yun motioned for everyone to come to the glass cover.

Hao Tian and Su Yu were the closest, and they clearly saw that something like a huge walnut was quietly placed in the glass cover, and under the illumination of the spotlights, the "walnut kernels" in this ravine showed a slightly yellowish waxy white, but on the surface of this "walnut kernels", a layer of green spots the size of a needle tip densely covered each groove. What's even more shocking is that a green filament grows in the middle of the entire brain, which is scattered into countless filaments like the tentacles of a jellyfish, and weaves into a huge fluorescent cage, as if the entire brain is enveloped and imprisoned in it forever.

Su Yu suddenly shuddered, she remembered the feeling of being unable to control herself, she quietly looked at the brain in front of her that had lost her freedom, as if she was looking at her former brain.

"It turns out that the brains of zombies are like this."

The students were shocked by what they saw, and Mao Yun's explanation came at the right time:

"This is the brain of zombies, and the green ones are the culprits that make humans zombies - ergot mutant."

She paused deliberately, drawing the attention of her classmates to her next words.

"Students, look at this green mutant ergot, it is the mother bacteria of the whole brain, and the place where it parasitizes is the corpus callosum of the human brain, which is a fiber bundle composed of fibers connecting the left and right cerebral hemispheres, but you little flower bones don't seem to understand very well."

Mao Yun pointed to the green ergot fungus: "Let's put it this way, it is parasitic on the intersection of nerves connecting the left and right hemispheres of the brain, thus controlling the entire brain, and therefore the entire nervous system of humans." ”

"Then why is it called ergot?" Some classmates asked.

“Good question!” Mao Yun pointed to his finger and praised: "Because this fungus did not appear out of thin air, it has existed for a long time." But in the past, it only parasitized in the ovary of gramineous plants such as rye, wheat, barley, oats, and goose crown, and then turned the ovary of these plants into their sclerotia, shaped like wheat grains, so it was called ergomycetes. ”

"There are many cases in history, people eat wheat parasitized by ergot fungus and have insanity, unable to control their own behavior, and even attack other people's symptoms, the famous St. Anthony's fire, you should have talked about it in the zombie history class, right?"

Mao Yun got a negative answer from the confused faces of her classmates, and she sighed in disgust: "This old monster Yu hasn't talked about this chapter yet." ”

"About the history of St. Anthony's fire, it is equivalent to a professor to tell you, we still focus on the category of zombie biology, the green ergot fungus you see now is a mutated ergot, it no longer parasitizes on herbaceous plants, it has chosen the strongest overlord on the earth - human beings as its parasite, and the most important thing is that it is very intelligent to parasitize the callosum of the human brain, we still don't know why it mutates this way, and how it mutates."

"However," Mao Yun's eyes flickered: "Regarding this, there is a research team that seems to have achieved some preliminary results, but because the person in charge of the research team has disappeared, the entire research has to be stopped." ”

"The person in charge is missing again?" Hao Tian said quickly: "I heard that the inhibitor research team is also like this. ”

Mao Yun glanced at her, was silent for a moment and replied: "Yes, it is their group, I heard that the person in charge of their group accidentally discovered the truth about the mutation of ergot bacteria when he was conducting inhibitor research experiments, but the results disappeared before they were published, and the experimental data and papers disappeared with her, and both studies were stalled, and even the inhibitors did not enter the final clinical trial stage." ”

After Mao Yun finished speaking, she lowered her eyes a little sadly: "The person in charge is called Xin Ai, and he used to be my student...... Very good girl......"

"It's a shame." She let out a long sigh.

The students were infected by this sadness for a while, and they all lowered their heads and looked at the green mutant ergot fungus in silence.

Su Yu and Hao Tian regretted the suspension of the study because they had seen the benefits of infection inhibitors to people.

Besides, if the truth about the ergot mutation is discovered, is it one step closer to eliminating the zombies?

However, why would a good person disappear with her research results at such a critical moment in research and development?

Su Yu suddenly had a chaotic thought in his mind - didn't anyone want the zombies to disappear? Even at the expense of killing researchers with great research results?

Once this kind of thought is generated, it can no longer be dispelled, and Su Yu suddenly remembered the long-standing school motto:

Block the gates of hell with my flesh and blood.

That girl, Zinn Ai, was doing this.
