"The ability to infect and bond other organisms and continue to grow is the main manifestation of the survival state of the banyan tree, and we don't know how far it can eventually grow."

Professor Qin continued to explain to the audience, "When we put the banyan tree in the vacuum laboratory and drain almost all the air, it will die in about half an hour. After we observed it, we found that all of its hearts stopped beating, the blood and black fluid throughout its body stopped circulating, and the corpse phenomenon began to appear, just like after the termination of normal life, which needs to be preserved with formalin. This is its state of death. ”

"In a state of death, its black liquor becomes inactive and is not contagious. When a creature approaches it, it can still have an unconditioned reflex, which is to make a sound as you have just seen. X-rays have been observed that the sound is squeezed by multiple organs in its throat, and the words spoken are presumed to be the last words spoken by the deceased before losing self-consciousness. When their eyes are closed, the reflex ends. As for the principle of this unconditioned reflex, it remains to be studied. ”

The large screen plays the relevant X-ray video, and everyone can clearly see how the vocal cords, trachea, and esophagus of the banyan tree are strangely squeezed.

The video has annotated text that reads "The tenth day of death", such a long time, and the tree in front of me has been soaked in formalin, can there still be unconditioned 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 and Xu Hai heard this, they immediately felt that they had grasped the key point!

"Like, very like." Wang Ruoxiang rolled her eyes and thought divergently: "Will those black liquids make the skin function as receptors?" As soon as you get closer, it may be stimulated by your breath gas, and its afferent and efferent nerves are still alive, so this reflex can appear. ”

"I think so too." Gu Jun thought and nodded, "This is indeed another creature. ”

The scratching reflex is quite an experiment with a heavy mouth. They had to first cut off the head of the experimental frog and remove the brain, at which point the frog was of course dead. But after a short time, when they smeared the skin of the frog's abdomen with pieces of paper stained with low-concentration sulfuric acid, the frog would use its hind limbs to scratch the smeared area, just like a corpse.

This is because the frog's undamaged spinal cord also has nerve centers that have multiple reflex arcs in the body, and they react when stimulated.

How can the banyan tree still howl when it dies, it may belong to this nature. It's just that the "short-term" after its death is very long for humans, and the external stimuli required for the reflex are the proximity of living beings.

"Scratch reflex." Professor Gu, who was listening to their discussion, hummed and said a little cold joke: "I was excited that there are really ghosts in the world just now." ”

Because Professor Qin said that this was an unconditioned reflex, Gu Jun was not the only one in the audience who thought of scratching the reflex, and many teachers and students muttered about it.

Everyone was still amazed, but they could finally use modern medicine to understand the freak thing, less scared, more shocked.

At this time, Sun Yuheng of the Qingyun University team raised his hand and asked, "Professor Qin, may I ask what is the situation that the pathogen you said is related to the banyan tree?" Is it a virus? How do they spread? ”

These three questions are also what every teacher and student present wants to know, especially the first question.

It's a pity that Professor Qin replied: "I can't say more about the pathogen here. This is a virus, and fortunately we have found that there are only two ways for it to spread, one is biological contact with the banyan tree of the pathogen, and the other is direct skin contact with the active black liquor of the patient in the mourning stage. ”

After listening to the answers to the last two questions, everyone breathed a sigh of relief, so that as long as the source of the banyan tree is extinguished and the patient is isolated and controlled, the situation will not be very bad.

The most feared are viruses like SARS that can be transmitted through respiratory droplets in close proximity, or even the Ebola virus, which can be transmitted through the air.

In contrast, although the ficus disease is a little more terrifying, it is the viruses that have the potential to break out like the Great Plague of the Black Death in the Middle Ages in Europe.

Many teachers and students have made up their minds that mankind has defeated SARS and controlled Ebola, and they are not afraid of a single banyan disease!

"It's probably not just Anaphylla that we're going to face in the future." Professor Qin's calm and solemn words pulled them back to the edge of hell, "You all have to be mentally prepared, this may be just the beginning, not an accident. ”

Just the beginning? The hearts of the people sank incessantly......

"I believe everyone understands the purpose of this competition." Professor Qin paused, "There are some things that are not suitable for the public to know at the first time, or even never need to know, otherwise it will cause some unnecessary panic and the entire social order will be affected." So the state has a secret department like ours. But now...... I can say that things are changing, and now we need more people to run our work. ”

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

Thinking about it, such a swagger made hundreds of them know about the existence of Banyan Disease, although there is no evidence such as mobile phones to take pictures, even if they spread it on the Internet, there is no picture and no truth, and it is regarded as a story and deleted in seconds.

But this kind of posture, so that they have a certain degree of knowledge, really needs them to participate, even if it is not directly to join the secret department.

Sure enough, Professor Qin continued, "It's a pity that not every single one of you has the qualifications we value. It was the first test just now, and about 1 in 10 people could pass. These students will be able to take the next assessment. Other people can participate in the general skills program, and the state has different arrangements for you, which acts as a bridge between our department and the general hospital. ”

The old man said solemnly: "So it can also be said that you have all been hired." The country needs you, and it needs more talents. This is not the only selection contest like this, and your ascent path will not be blocked, so work hard. ”

Professor Qin's eyes gradually looked at the seats of Dongda, looked at Gu Jun in the middle and back rows, and said: "As for our department, the qualifications we want, one is will, and the other is medical technology, both of which are indispensable. Okay, let's rest for a while. ”

Gu Jun thought, the situation must have been quite serious, the matter of Longkan, Laisheng Company was suddenly ready to move, and the banyan disease was ......

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

When the words fell, Professor Qin and the judges walked to the aisle, and the staff finally pushed the big iron cage back.

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

Sometimes, ignorance is a blessing.

Most of the students have a good idea of whether they have passed this round of assessment. Some people understand that they really don't have that kind of qualifications, if they stand next to the alien banyan tree like Gu Jun just now, their legs will be scared, and they don't want to join that secret department even if they have the opportunity.

Others hope and desire to enter the next round, into that mysterious world. Gu Jun is one of them.

After a while, the shortlist was announced on the big screen, and the names of the students were listed on it, and hundreds of people in the audience looked at it intently.
