On the dilapidated wall hung a kerosene lamp with a strange shape, and the shade was stained with some old blood, making the hazy light seem to be bloody.

It was a small basement with a low ceiling and a lot of debris, some of which had bent the old wooden floor as if it would break the planks with one foot. In the middle of the basement there is a long wooden table, the light of the candles flickering, reflecting the extremely cloudy color of the tabletop, only after a lot of dirt, dirt penetrated into every wood grain, will it become like this......

In the center of the table seemed to be the corpse of an alien creature, and the stench filled the air, and there seemed to be a figure standing at the table......

Gu Jun wanted to see clearly, but the light and shadow of these illusions became faint, and what he saw in front of him was still the dissecting table, and he was in the gymnasium.

"These tissues in this lung seem to be bird air sacs." Wang Ruoxiang's tone was very surprised, and her eyes widened, "It's just bigger." ”

"It's weird." 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 of this dissecting table was played on the big screen.

The outside of this lung has six enlarged membranous sacs, all of which are connected to the bronchial tubes, and the walls of the sacs are covered with capillaries, showing the vitality of the past.

Gu Jun looked at those air bags, and there was a feeling surging in his heart...... It's an amazing structure.

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

The lungs are one of them. The human lung is a two-way lung, and the air comes in and out by the same path, and it also needs to do the work of exchanging and storing gases, which makes the new air diluted by the residual anoxic air in the lungs, which is inefficient. Moreover, the bubble wall is also very fragile, and emphysema is prone to occur.

But the lungs of birds are different, they have anterior air sacs, lungs and rear air sacs, and these three parts have a clear division of labor, the lungs are only responsible for letting air through, 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 oxygenated air passes through the lungs with every inhale and exhale, which is very efficient, which is the "double breathing" of birds.

As a result, birds can fly for long periods of time and reach higher altitudes than humans.

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

"Take it down and take a look." Gu Jun condensed his mind, held the scalpel with a pen gesture, and leaned over to cut off the pleura, nerves, and blood vessels connected to the lungs, as well as the tube belts where the air sacs were attached to the surrounding parts, and maybe the lung roots and lung ligaments, a bunch of tissues.

Because this was not drawn on the incomplete map, he had to be careful not to cut any of the tubes in every operation. It's not just because of Professor Qin that they're staring, it's also a requirement for the completion of the task's anatomy.

Wait for Gu Jun to take this lung intact, and then dissect it with Wang Ruoxiang and Cai Zixuan.

Everyone can also observe more clearly, and the more they look, the more surprised they are by this lung, which is simply a delicate and gorgeous plan for every artery and vein.

"This creature should be able to climb higher and dive deeper." Cai Zixuan sighed, "This lung works too efficiently. ”

"I want this lung." Wang Ruoxiang said, "It must be very suitable to participate in The Voice." ”

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

After the three of them finished dissecting the lungs, they moved down to the mediastinum, and then the pericardium, and then Gu Jun used a scalpel to cut off the large blood vessels in the pericardium and take out the heart. The heart was one size larger than the human body, and although it was a lifeless mass now, it must have been beating with strength when it was alive.

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

The human heart is also imperfect, especially with a rather nonsense flaw - there is only one artery for each area of the heart, and the right atrium and right ventricle are supplied by only the right coronary artery. If this artery is blocked, the right atrium and right ventricle will be deprived of oxygen, and then the myocardial infarction and heart attack will occur......

Regardless of whether humans were created by the Creator or evolved, this shabby design must be badly reviewed.

You don't need to be an alien, many mammals of the same species on Earth, such as dogs, have multiple blood vessels in different paths to the dog's heart. If one is plugged, the others can be topped. So the dog's lungs may not be a good thing, but the dog's heart is.

"Each of the four heart chambers is supplied with four coronary arteries." Wang Ruoxiang counted and exhaled lightly, "This will be a long life." ”

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

But Professor Qin looked serious, these strange organs were not something worthy of praise in them.

"Professor Gu, could this still be a human lesion?" Xu Hai asked incomprehensibly, Zhang Haoran and He Yuhan couldn't figure it out, is this still a disease?

"Students, I don't know." Professor Gu sighed sincerely, his old face was a little more confused, what had he studied for so many years?

On the other side, Gu Jun continued to bury his head in the operation, dissecting these coronary arteries on the heart one by one.

With each section, his heart sank a little more, and he gradually felt the mood of the notes on the mutilated map, both amazed at the structure of the creature and felt for his own construction...... Panic. If there is no defect in the lungs, there is no defect in the heart, is there no defect in other organs?

In particular, what about its brain?

The reason why humans can dominate other species and suppress tigers and lions is because of intelligence.

What is the level of intelligence of this creature?

If the human body has no advantage, and the brain has no advantage, then ......

Complex emotions were entangled in the subconscious, and suddenly, Gu Jun's head was a little painful, and the light and shadow of the illusion flashed in front of him.

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

It was still a little blurry, but this time he could see it more clearly. On the filthy long wooden table lay a humanoid corpse, dark-skinned and with long limbs, its chest dissected, the slab tossed aside, and the bloody glow of kerosene lamps and candles.

There was a rusty iron plate on the side of the table, and a heart was placed in it, and its black and red blood flowed out of the plate, falling down the table, dripping on the floor.

Gu Jun vaguely saw that the figure standing at the table was holding something that looked like a fountain pen, leaning over and drawing something on a stack of yellowish parchment on the table...... It's the old structural map! But in this illusion, it is completely new.

The man looked at the corpse on the table as he drew a diagram of the structure on a piece of paper, made annotations, and wrote down notes.

He muttered something as he wrote, unable to read his face or understand his words, but could hear his surprise, his panic, his confusion, his confusion......

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

When he muttered the fourth time, he also wrote it on the map for the fourth time.

Gu Jun's heart ached, and he suddenly seemed to be able to understand this sentence, and knew what the four lines of different text repeated at the end of that note meant.

"They're better than us?

Are they better than us?

Are they better than us?

Are they better than us? ”
