"It is the main manifestation of the survival status of the banyan tree, and we don't know how far it can grow eventually."

Professor Qin continued to explain to everyone in the audience, "When we put the banyan tree in the vacuum laboratory and pumped almost all the air away, the banyan tree would die in about half an hour. After observation, we found that all its heart stopped beating, the blood and black liquid in the whole body stopped circulating, and corpses began to appear. Just like after the life activities of ordinary bodies ended, it needed to be preserved with formalin. This is its death state."

"In a state of death, its black liquid is inactive and not contagious. When a creature approaches it, it still has a non-conditioned reflex, which is what you just saw. We observed with X-ray perspective that the sound is emitted by the squeeze of multiple organs in its throat. The words said are inferred by the last moment before the deceased loses self-awareness. When their eyes are closed, the reflex will end. As for the principle of this non-conditioned reflex, it remains to be studied."

The relevant X-ray perspective video is played on the large screen, and everyone can clearly see how the vocal cords, trachea, esophagus, etc. of the banyan tree are squeezing strangely.

The video has a marked text that shows "Day Tenth Day of Death". It took such a long time, and the tree in front of me has been soaked in formalin, can it still have non-conditioned reflexes...

Gu Jun remembered an animal experiment he had done in class and said to others: "Do you think this looks like a frog's scratching reflex?"

When Cai Zixuan, Xu Hai and the others heard this, they immediately felt that they had grasped the point!

"It looks very similar." Wang Ruoxiang turned her eyes and thought divergently: "Can those black liquids make the skin function as a receptor? As soon as you approach, your breathing gas may stimulate it. Its afferent and efferential nerves are still energetic, so this kind of reflex can occur."

"I think so too." Gu Jun nodded as he thought, "This has indeed become another creature."

Scratching and reflexes are an experiment that is very heavy. They have to cut off the head of the experiment frog and remove the brain. The frog is of course dead at this time. But in a short time, when they apply the paper piece stained with low concentration of sulfuric acid to the frog's abdominal skin, the frog will use its hind limbs to scratch the applied position, just like a zombie.

This is because the undestroyed spinal cord of a frog also has a nerve center, and there are multiple reflex arcs in the body, which will cause reflexes when stimulated.

How can the alien banyan tree still howls when it dies, it may belong to this nature. However, the "short-term" after its death is very long for humans, and the external stimulation required for reflection is the proximity of organisms.

"Tick the reflex." Professor Gu, who listened to their discussion, nodded and said a small cold joke: "I was excited just now that there are really ghosts in the world."

Because Professor Qin said that this was a non-conditioned reflex, the audience thought that Gu Jun was not the only one who scratched the reflex, but many teachers and students muttered and discussed it.

Everyone was still surprised, but they could finally use modern medicine to understand the weird thing, less fear and more shock.

At this time, Sun Yuheng from Qingyun University team raised his hand and asked, "Professor Qin, what is the situation you are talking about with the banyan tree? Is this a virus? What are their transmission methods?"

These three consecutive questions were also what every teacher and student present wanted to know, especially the first question.

Unfortunately, Professor Qin replied: "I can't say much about the pathogen. This is a virus. Fortunately, we have discovered that it has only two ways of spreading. One is biological contact with the banyan tree of the source of the disease, and the other is direct skin contact with the active black liquid of the patients in the mourning and changing stage."

After hearing the answers to the last two questions, everyone breathed a sigh of relief. As long as the banyan tree in the source of the disease is wiped out and the patient is isolated and controlled, the situation will not be very bad.

What I fear most is viruses that can be transmitted through close-range respiratory droplets like SARS, and even Ebola virus that can be transmitted through the air.

In contrast, although the banyan disease is a little scary, only those viruses may have an outbreak of an epidemic like the Black Death plague in the Middle Ages in Europe.

Many teachers and students have calmed down. Humans have overcome SARS and controlled Ebola, so they are not afraid of a strange banyan disease!

"What we will face in the future may not be just the disease of Yifang." Professor Qin's calm and solemn words pulled them back to the edge of hell. "You all must be mentally prepared. This may be just a beginning, not an occasional event."

Just the beginning? Everyone's hearts kept sinking...

"I believe everyone understands the purpose of the selection of this competition." Professor Qin paused, "Some things are not suitable for the public to know at the first time, and even never need to know them, otherwise it will cause some unnecessary panic and the entire social order will be affected. So the country has a secret department like us. But now... I can say that the situation is changing, and now our work needs more manpower to operate."

Everyone heard the point again, and the situation was changing!

I think so, so swaggeringly made hundreds of them know about the existence of Yifang disease. Although there was no evidence taken by mobile phones, even if they spread it on the Internet, there was no picture or truth. They were treated as a story and deleted in seconds.

However, this attitude makes them informed to a certain extent, and they really need to participate, even if they are not directly joining the secret department.

Sure enough, Professor Qin then said: "I'm sorry that among you, not every one has the qualifications we value. Just now, it was the first assessment, and about one-tenth of them could pass. These students will be able to conduct the next assessment. Others can participate in ordinary skill projects. The country has other arrangements for you, which is to serve as the bridge between our department and ordinary hospitals."

The old man said solemnly: "So it can be said that you have all been hired. The country needs you and more talents. There will be no only one such selection competition, and your upward channel will not be blocked. Work hard."

Professor Qin's eyes gradually looked at the seat of Dongda University, looked at Gu Jun in the middle and back row, and said, "As for our department, the qualifications we need are, one is will, and the other is medical technology. None of them are missing. Okay, let's take a break first."

Gu Jun thought that the situation must have been quite serious. In Longkan, Laisheng Company suddenly became tempted to move, and Yifang was sick...

These should not be separate events, but have a connection that he does not know yet.

After the words came over there, Professor Qin and a group of judges walked towards the aisle, and the staff finally pushed the big iron cage back.

The thing disappeared in the venue, and the air suddenly became fresher, and the teachers and students felt that the dark clouds above their heads were gone.

Sometimes, ignorance is really a blessing.

Most students know whether they have passed this round of assessment. Some people understand that they are not that kind of qualification. If they stand next to a strange banyan tree like Gu Jun just now, their legs will be scared, and even if they have the chance, they will not want to join that secret department.

Some people hope to enter the next round and enter that mysterious world. Gu Jun is one of them.
