The drill bit touched the carapace, grinding out a squeaky sound, the drill bit gradually penetrated deep into the carapace, and some fine powder appeared at the drill hole.

Everyone watched intently, even the aliens.

Ye Han didn't know what the alien thought, but the alien struggled with all his might, and a series of sawing sounds like wood came out of his mouth.

No one understands alien language, but if you think about it with your ass, there must be nothing good in the alien's mouth...... No matter who is put in the alien position, the heart will be full of resentment, and it is normal to scold a few words.

Ye Han originally wanted to restrain the alien by hand, so as not to affect the researchers with his struggle, but this mobile hospital bed was much heavier than expected, plus he was tied firmly, no matter how hard the alien tried, his body was always motionless, and it did not affect the work of the research staff at all.

Well, the institute must have thought of this a long time ago, so it deliberately equipped a suitable mobile bed.

As the drill bit deepened, the researcher became more and more cautious in his movements, for fear that he would drill deep if he was not careful.

After exactly two minutes, the drill bit finally penetrated the carapace, and the researcher who operated the drill let out a sigh of relief and cautiously removed the drill bit, and dark red blood immediately gushed out of the hole.

The researcher immediately put the vacuum tube in and drew blood from the borehole.

But there was only a little blood gushing out of the borehole and there was no movement, and it was clear that there were no blood vessels under the borehole.

The researchers are also very helpless about this, no one knows the body structure of the alien at the moment, so naturally it is not clear where the blood vessels are.

When Xu Jiaye saw this scene, he said without hesitation: "Change to a coarse one!" ”

The researcher immediately complied, replaced it with a drill bit the thickness of a nail, and re-operated it.

This time, the borehole was much larger, and the amount of bleeding increased significantly.

The researchers shoved the needle of the vacuum tube directly into the borehole, and the alien blood slowly filled the vacuum tube.

After absorbing enough blood, several researchers hurried away with blood samples.

At this time, blood was still leaking from the borehole, and the researcher in charge of the borehole did not know what to put on the borehole, and stuffed something into the borehole to block the borehole.

Ye Han's cheeks twitched, this is to stop the bleeding for aliens? This style is too rough for his grandmother, right?

It's not that he pities the aliens, but he simply feels that he can't play with the limited experimental object so quickly.

At this time, Xu Jiaye said again: "Keep checking!" ”

The people who were originally around the aliens all retreated and replaced with another person.

Ye Han's eyes were sharp, and he saw that the person's ID hanging on his chest had his name on it: He Qiang.

He Qiang looked the aliens up and down, and the aliens who struggled to no avail seemed to have resigned themselves to their fate, and honestly lay there without moving.

He Qiang seemed to have seen enough, took out a tape measure made of unknown materials, opened it and compared it to the alien: "One meter sixty-two tall!" ”

Another researcher immediately jotted down the data.

He Qiang continued to measure the alien's head: "Record, head length 22, width 14, height 18, no hair!" ”

Speaking of this, he took out a very inconspicuous little hammer and knocked on the door of the alien's head, making a stiff bang: "The hardness of the braincase is good!" ”

Putting away the hammer, He Qiang took out a mini flashlight again, opened it and shone it into the alien's eyes, and the alien's pupils instantly constricted.

He Qiang was surprised: "It's interesting, their pupils look round, but they are actually petal-shaped, it's really strange!" ”

When Ye Han heard this, he immediately glanced at the alien's eyes, and sure enough, that pupil was not round, but like a flower, with a very regular shape, but there was no way to accurately describe its shape.

He Qiang looked at Xu Jiaye: "This kind of eye is too strange, how did they evolve?" ”

Ye Han said: "It doesn't have to be natural evolution, maybe they changed it later." ”

"Makes sense, too!" He Qiang nodded, changed the angle of the light, and observed the changes in the pupils, he found that the pupils of aliens were very interesting, and the "petals" in different positions did not change together, but changed according to the changes of the light source.

He Qiang couldn't figure out the reason, but he knew that there must be some unknown reason why alien eyes evolved like this.

He Qiang didn't dwell on this issue, he continued to check down: "The nose is flat, double holes!" ”

"A pair of ears, the pinna is slightly larger, and the position is a bit forward...... It may have evolved to cope with the low-pressure environment! ”

Ye Han didn't bother to mention the issue of natural evolution again, let the research institute study it casually!

At this time, He Qiang found the alien's mouth, he took out a small hammer, stuffed the hammer handle into the alien's mouth, and pried the alien's mouth open with a light pull: "Wow, its lip structure is similar to a shutter, soft and retractable...... There are teeth in the mouth, and the front is flattened, which is conducive to cutting; The coarse flat at the back is easy to grind...... Didn't find a tongue! ”

After He Qiang checked his facial features, he moved his gaze to the alien's neck, and he put a hammer against the alien's head, making the alien turn his head left and right: "The range of movement of the strength is 210 degrees......"

Ye Han took a few steps back, leaned over to Xu Jiaye's side and whispered, "Director Xu, I want to ask a question!" ”

Xu Jiaye immediately said: "You say! ”

Ye Han said: "Why do aliens look so similar to humans?" ”

Xu Jiaye was a little confused: "Where is it like?" He doesn't agree with that at all.

"It's like everywhere!" Ye Han said, "A head, a torso, hands and feet, this is too coincidental, right?" ”

Xu Jiaye looked suddenly: "Hey, you said this, this should be a law of nature, to put it simply, there is a certain similarity in evolution...... How can I tell you? Most creatures can be divided into heads, chest, abdomen, and limbs, and there are some natural laws here! ”

"What kind of pattern?" Ye Han broke the casserole and asked to the end.

Xu Jiaye was a little difficult, but quickly said: "Let's take an analogy, in order to facilitate movement, the legs are all long and lower; In order to facilitate the work, the hands are long and topped; The head either has an upper edge like a human or a front like a wolf, both for ease of observation; The position of the facial features is not arbitrarily long, and the two eyes are three-dimensional because of what they see; The two ears are convenient for judging the direction of the sound source...... That's probably what it means! ”

Ye Han thought for a while and said, "I seem to understand!" ”

He remembered that when he was a child, he had a cold, one nostril was blocked and he could not breathe, and the other nostril could still breathe normally, which should also be a sign of adaptation to the environment.

And the laws of nature are not only useful on Earth, but also on other planets, so aliens can grow like this.

Well, there is nothing wrong with Xu Jiaye's answer, it must be a full score!
