Plague Doctor

A curiously shaped kerosene lamp hangs on a broken wall and some old blood stains on the lampshade make the blurry lights seem to be bloody.

This is a small basement with very low ceilings, full of clutter, and some of the old wooden floors bent down as if stepping on one foot would break the plank. There is a long wooden table in the middle of the basement, the light of the candles shakes, reflecting the incredibly cloudy colour of the desktop. This will only become so if it has been stained with a lot of dirt and has been penetrated by the dirt in every wooden pattern...

Right in the center of the table is like a dead creature, the stench of smoky air is spreading, and there seems to be a figure standing at the table...

Gu Jun wanted to see it better, but these illusions became faint. What he saw in front of him was an autopsy table, and he was in the gym.

“These tissues in this lung seem to be avian airbags.” Wang Ruoxiang was surprised, his eyes were wide open, "but even bigger. ”

“That's weird.” Cai Zixuan's eyes were slightly reddened with wrinkles. He was the voice of all the teachers and students in the field, and there was this anatomical table on the big screen.

The outer surface of this lung grows with six vast membranous sacs, all connected to the bronchi, filled with capillaries on the walls of the sac, revealing the vibrancy of the past.

Gu Jun looked at the airbags, and there was a feeling that was pouring... such a fabulous structure.

Humans always pretend to be the spirits of all things, and the human body is indeed very delicate, but not perfect. Instead, it has many defects, and some organ structures are not better used than others on Earth.

Lungs are one of them. The human lung is a bidirectional lung, and air comes in and out in the same path, and there is also a need to exchange and store gas, which makes the new air diluted by the remaining oxygen-deficient air in the lung and inefficient. And the bubble walls are fragile, prone to emphysema.

But unlike the lungs of birds, which have anterior airbags, lungs, and posterior airbags, the division of labor between these three parts is clear: the lungs only allow air to pass through, and the airbags only store gas without gas exchange. This allows fresh air to keep coming and going in the lungs at constant speeds, and every breath of oxygenated air passes through the lungs, very efficiently, which is the bird's "double breath."

And so birds can fly in time, and they can reach higher altitudes than humans.

Humans may say, "Different species have different needs," but now, this human species on the anatomy table actually has a bird lung.

“Take it off and see.” Gu Jun stirred up his heart and held a scalpel with a pencil gesture, leaning down to sever all the pleura, nerves and blood vessels connected to this lung, as well as the ductal bands that the airbags attached to the surrounding area, and perhaps the root and ligaments of the lungs, a pile of tissue.

Because this is not painted on the residue map, he must be careful every step of the way and not cut any tube. It's not just because Professor Qin is watching them, it's also a requirement for task anatomy completion.

Wait for Gu Jun to properly remove this lung before dissecting it with Wang Ruoxiang and Cai Zixuan.

People can also see better, and the more they look at it, the more surprised they are about this lung, the more exquisite it is that every movement and vein has a gorgeous plan.

“This creature should be able to climb higher and dive deeper.” Cai Zixuan was emotional, "the lungs worked too efficiently. ”

“I want this lung.” Wang Ruoxiang said, "This must be a good sound for you to take part in. ”

But soon, she wanted the heart of this creature even more.

Once the three of them had dissected their lungs, they lowered their hands mediastinally, followed by the pericardium, and Gu Jun cut off the large blood vessels with an anatomical knife in the pericardium to remove the heart. This heart is one size bigger than the human body, and although it is now a dead body, it must be beating full of strength when it is alive.

They continued to observe and dissect the heart, adding another surprise.

The human heart is equally imperfect, especially with a rather frivolous defect - each area of the heart is supplied with only one artery, and for the right atrium and right ventricle, only the right coronary artery. If this artery is blocked, the right atrium and right ventricle will be hypoxic, followed by myocardial infarction, heart attack...

Whether human beings are created by the Creator or evolved, this cold design has to be underrated.

You don't need to be heterogeneous, but many mammals that are also species of the Earth, like dogs, have multiple blood vessels supplied to their hearts in different pathways. If one is plugged, the others can be topped. So dog lungs may not be good, but dog hearts are.

“Each of the four cardiac cavities is supplied with four coronary arteries.” Wang Ruoxiang counted and exhaled softly, "it will live a long life. ”

Teachers and students alike sighed and sighed.

But Professor Qin's face was serious, these strange organs were there, not something to praise.

“Professor Ancient, could this still be a human lesion?” Xu Hai didn't understand. Zhang Hao ran and He Yuhan couldn't figure it out. Is this still a disease?

“Class, I don't know.” Professor Ancient sighed honestly, with some more confusion on his old face, what has he been studying for so many years?

On the other hand, Gu Jun continued to bury his head and cut these coronary arteries off from his heart one by one.

Every time he cut one, his heart became a little heavier and gradually felt the mood of those notes on the map of the debris, both amazed by the structure of the creature and panicked by the structure of himself... No defects in the lungs, no defects in the heart, no defects in other organs?

Complex emotional entanglement in the subconscious. Suddenly, Gu Jun's head was a little sore, and the illusion appeared in front of him.

He felt himself in that dark, narrow basement again, and there was a muttering coming into his ear, the kind of weird alien language...

There was still some ambiguity, but this time he saw it better. There was a human corpse on that dirty long wooden table with dark skin and long limbs. The chest had been dissected. The plate bone had been thrown aside, and the kerosene lamp and candles lit up this bloody spot.

There is a rusty iron plate at the table, and one heart is in the plate, and its black and red blood flows out of the plate, falling off the table and dripping on the floor.

Gu Jun sees that the person standing at the table is holding something like a pen, lying down on a pile of yellow parchment paper on the desktop and writing what... is that old structure map! But in this illusion, it's brand new.

The man pointed at the body on the table and drew a structural chart on the paper, marked it, and wrote down his notes.

He writes while muttering, can't understand his face, can't understand his words, but can hear his surprise, panic, panic, confusion...

The further down the notebook, the more rigid the person was and the deeper the tone, the slower he repeated his words over and over, as if he were about to die.

When he mumbled for the fourth time, he wrote for the fourth time on the map.

Gu Jun's heart ached and suddenly he seemed to understand the phrase. He understood what the four lines of alien text repeated at the end of the note meant.

“They're better than us?

They're better than us?

They're better than us?

They're better than us? ”
