Plague Doctor

A kerosene lamp with a strange shape was hung on the dilapidated wall, and the lampshade was stained with some old blood stains, making the hazy light seem to be tinged with blood.

This is a small basement with a low ceiling and piles of debris everywhere, some of which have bent the old wooden floor, as if the wooden boards would be broken if one stepped on it. There is a long wooden table in the middle of the basement. The light from the candles flickers, reflecting the extremely turbid color of the table. It will only become like this when it has been stained with a lot of dirt, and the dirt has penetrated every wood grain. ...

Right in the middle of the table was the corpse of a strange creature, filled with a foul stench, and there seemed to be a figure standing beside the table...

Gu Jun wanted to see clearly, but these phantom lights and shadows became erratic and faint. What he saw in front of him was still the dissecting table, and he was in the gymnasium.

"The tissues of this lung seem to be bird air sacs." Wang Ruoxiang said in surprise, her eyes widened, "It's just bigger."

"It's so strange." Cai Zixuan wrinkled his slightly red and swollen eyes. What he said was really the voice of the teachers and students in the audience, and the situation on the dissection table was played on the big screen.

There are six enlarged membranous sacs growing on the outside of this lung, all of which are connected to the bronchi. The walls of the sacs are covered with capillaries, showing the vitality of the past.

Looking at those airbags, Gu Jun felt a throbbing feeling in his heart... Such a structure is really amazing.

Human beings always claim to be the spirit of all things, and the human body is indeed very exquisite, but it is not perfect, but has many defects, and some organ structures are not as easy to use as those of other earth species.

The lungs are one of them. The human lung is a two-way lung, and the air enters and exits through the same path, and it also needs to do the work of exchanging and storing gas, which makes the newly entered air diluted by the residual hypoxic air in the lung, which is inefficient. Moreover, the air bubble wall is still very fragile, prone to emphysema.

But the lungs of birds are different. It has front air sacs, lungs and rear air sacs. These three parts have a clear division of labor. The lungs are only responsible for passing air, and the air sacs are only responsible for storing gas but not for gas exchange. In this way, fresh air can continue to come and go in the lungs at a constant speed, and oxygen-containing air passes through the lungs with each inhalation and exhalation, which is very efficient. This is the "double breathing" of birds.

It is also because of this that birds can fly in time and reach higher altitudes than humans.

Humans may be able to say that "different species have different needs", but now, this humanoid creature on the dissecting table has a bird lung.

"Take it off and have a look." Gu Jun condensed his mind, held the scalpel with a pen-like gesture, and bent over to cut off the pleura, nerves, and blood vessels connected to the lung, as well as the tube belts attached to the surrounding parts of the air sac, And maybe lung roots and lung ligaments, a bunch of tissue.

Because this is not drawn on the incomplete map, he must be careful in every operation, not to cut any pipes. It's not just because Professor Qin and the others are watching, it's also a requirement for the completion of the task anatomy.

After Gu Jun took out the lung intact, he and Wang Ruoxiang and Cai Zixuan will dissect it.

Everyone can observe more clearly, and the more they look at it, the more they are amazed by this lung, almost every artery and vein has a delicate and gorgeous design.

"This kind of creature should be able to climb higher and dive deeper." Cai Zixuan said with emotion, "These lungs work so efficiently."

"I want this lung." Wang Ruoxiang said, "It must be very suitable to take part in the good voice."

But soon, she wanted the creature's heart even more.

After the three people dissected the lungs, they started working on the mediastinum, and then the pericardium. Gu Jun then used a scalpel to cut off the large blood vessels in the pericardium, and took out the heart. This heart is one size larger than the human body. Although it is a lifeless mass now, it must have beat with strength when it was alive.

They continued to observe and dissect the heart, and they were amazed again.

The human heart is not perfect either, with one rather nonsensical flaw in particular—each region of the heart is fed by only one artery, and in the case of the right atrium and ventricle, only the right coronary artery. If this artery is blocked, the right atrium and right ventricle will be starved of oxygen, and then myocardial infarction, heart attack...

Regardless of whether humans were created by the Creator or evolved, this shabby design deserves a bad review.

You need to know that they don’t need to be heterogeneous. Many mammals that are also earth species, such as dogs, have multiple blood vessels in different paths to supply blood to the dog’s heart. If one is plugged, the others can be put on top. So dog's lungs may not be a good thing, but dog's heart is.

"There are four coronary arteries supplying blood to each of the four heart chambers." Wang Ruoxiang counted and exhaled softly, "This will lead to a very long life."

The teachers and students in the audience also murmured and sighed again and again.

But Professor Qin and the others looked serious. These strange organs are not something worthy of praise.

"Professor Gu, is it possible that this is caused by a human disease?" Xu Hai asked in confusion, Zhang Haoran and He Yuhan also couldn't figure it out, is this still a disease?

"Students, I don't know." Professor Gu sighed sincerely, with a little confusion on his old face, what have he been studying for so many years?

On the other side, Gu Jun continued to concentrate on the operation, and cut off the coronary arteries in the heart one by one.

Every time a piece was dissected, his heart sank a little more, and he gradually felt the mood of the notes on the incomplete atlas. He was amazed at the structure of this creature, and felt... panicked at his own structure. There is no defect in the lungs, no defect in the heart, are there no defects in other organs?

subconsciously

Complicated emotional entanglement, suddenly, Gu Jun's head felt a little heavy, and a phantom light and shadow flashed in front of his eyes.

He felt that he was in that dark and cramped basement again, and there was a murmur reaching his ears, it was that kind of strange foreign language...

It was still a little blurry, but this time he could see it more clearly. On the dirty long wooden table was a humanoid corpse with dark skin and long limbs. The chest had been dissected, and the bone was thrown aside. With this piece of blood.

There was a rusty iron plate beside the table, and a heart was placed on the plate, its black and red blood flowed out of the plate, fell to the table, and dripped on the floor.

Gu Jun vaguely saw that the figure standing by the table was holding something that looked like a pen, leaning over to draw something on a stack of yellowed parchment on the table... It was the dilapidated Structural Atlas! But in this illusion, it's still whole new.

While comparing the corpse on the table, the man drew a structural diagram on the paper, made annotations, and wrote notes.

He was mumbling something while writing, and he couldn't read his face or understand his words, but he could hear his surprise, hesitation, panic, and bewilderment...

The further down the note was written, the stiffer the man's posture became, and the more lifeless his tone became, he slowly repeated his words over and over again, as if he was about to die.

When he uttered the fourth time, it was also the time to write the fourth time on the map.

Gu Jun felt a pain in his heart, suddenly seemed to understand this sentence, and understood the meaning of the four lines repeated at the end of that note.

"Are they better than us?

Are they better than us?

Are they better than us?

Are they better than us? "
