"Planetary code?" When several members of the team heard this answer, their faces showed puzzled expressions at the same time.

"Yes, planetary code." Lang Xiaonian confirmed again.

"Oh, don't sell it, tell me quickly, what does this string of numbers represent?" Eve wanted to know the meaning of the numbers so much that she urged with some annoyance.

Lang Xiaonian saw everyone's expressions, and a smile appeared on his face.

He is a relatively inconspicuous one in the military scientific research class.

Of course, being selected into the military scientific research class is a talent that is one in a million.

However, he does have few highlight moments in the military scientific research class, and he belongs to the kind of person who is difficult to remember.

If it was in another college class, with his ability, it would definitely be the focus.

However, in the military scientific research class, it seems somewhat ordinary.

That's not to say he doesn't have merit, though.

In fact, he has many advantages, one of which is his knowledge of astronomy.

Since his father was a professor of astronomy, he was exposed to it since he was a child, so he naturally knew a lot about astronomy.

To say that it understands is actually a very modest statement.

He dared to disagree with his father on the asteroid belt, not only because he was young, but also because he had already formed his own thinking and opinions in astronomy, so he dared to argue with his father in astronomy.

In the past, in the military scientific research class, astronomy was not used, so he did not have a highlight moment.

Now, seeing the brightest stars in the military research class and asking questions to him at the same time made him feel that he had a presence for the first time in the class.

In the past, Fang Yuan felt that there were some students in the military scientific research class who were not very useful.

For example, this Lang Xiaonian, his combat power is considered strong among ordinary awakened people, but in the military scientific research class, it is relatively ordinary.

Most of the high-risk combat missions, Lang Xiaonian did not participate.

There is more than one student in a military scientific research class like him.

Most of the time, these trainees whose strength is not prominent are a bit redundant in military scientific research classes.

However, it now seems that the cadets who have been selected for the military scientific research class must have some outstanding points in themselves.

For example, this Lang Xiaonian.

Obviously, his strength is astronomy.

"How far have you learned astronomy?" Fang Yuan asked curiously.

Lang Xiaonian pushed the glasses on the bridge of his nose and replied, "It's so-so." I've read most of the books in my dad's study. ”

When he pushed his glasses, his expression looked a little shy.

People with this kind of personality are usually more humble.

Therefore, when he said "I have basically seen everything", he roughly means "memorized it well".

"Captain, don't interrupt, let him tell him the meaning of this sequence, my curiosity is about to explode." Eve saw Fang Yuan interrupt and asked an irrelevant question, and suddenly became a little anxious.

Fang Yuan glanced at Han Youwei and said, "We here, it doesn't seem that no one knows the meaning of this string of numbers. ”

Everyone followed Fang Yuan's gaze.

Han Youwei pursed her lips and smiled, lowered her head slightly and said, "I do know the meaning of this string of numbers, but I only know a little. ”

He is also a shy person, never forgetting to be humble.

Fang Yuan gave an evaluation in his heart.

Eve learned that Han Youwei knew the meaning of this string of numbers, and immediately grabbed Han Youwei's arm and shook it: "Youwei, say it quickly, you say it quickly, they are a group of bad people, and they are about to suffocate me." ”

"Okay. Then I'll say it first, Lang Xiaonian, if I say something wrong, you can correct it. Han Youwei said.

"Good...... No, not to be corrected. Let's talk about it together. Lang Xiaonian hurriedly waved his hand.

Han Youwei took the tablet and added a formula to it.

y=（x+4）/10

Everyone looked at this company and was even more confused.

Originally, there was only a series of numbers of unknown meaning on it, but now there is an additional clueless company.

Niu Dazhi's head was about to explode, he grabbed his scalp with both hands, and shouted: "Can you finish talking all at once, don't keep drawing these ghost talismans?"

"I thought I would be able to say goodbye to math after graduating from high school, what are you doing now? My head is going to explode! ”

Fang Yuan looked at this formula, suddenly thought of something, pointed to the formula and asked, "What is the unit of this y?" ”

Han Youwei replied with a smile: "Astronomical units." ”

"Here we go again, what is an astronomical unit? Can you speak human language? Niu Dazhi grabbed his scalp with both hands again, looking like he had exploded.

"The astronomical unit is the distance from the sun to the earth. We have customized this distance to 1 astronomical unit to facilitate the study of astronomy. 1 astronomical unit, equal to 149.6 million kilometers. It's a long distance anyway. Lang Xiaonian helped explain.

Since human beings live on the earth, many of the doctrines established by human civilization are based on the earth.

The same is true for astronomical units, 1 astronomical unit is the distance from the sun to the earth.

After Fang Yuan confirmed that the unit of the formula y=(x+4)/10 was an astronomical unit, he already knew the meaning of this string of numbers, and a mysterious smile appeared on his face.

Han Youwei saw the smile on Fang Yuan's face and knew that he had understood, so she asked, "It seems that you already know, it seems that you don't need to explain." ”

Niu Dazhi scratched his scalp for the third time and shouted: "He knows it's useful?" I don't know. Can you please stop doing this? Be a person. To put it bluntly, what does this string of numbers mean? If you don't say anything more, I'll beat someone! ”

Eve was also anxious, but seeing that Niu Dazhi was anxious, she was very happy and said, "Who can you beat?" ”

After she finished the beef balls, she hurriedly turned around, shook Han Youwei's arm, and said, "Youwei, just hurry up." ”

"In fact, this string of numbers represents the distance between the eight planets and the sun."

Han Youwei called up the galaxy map of the solar system and began to explain the meaning of the string of numbers: "You see, this is the galaxy map of the solar system.

"In this diagram, the orbits of the eight planets, which are eight circles, orbit the Sun in the center.

"The first circle is Mercury, which is 0.4 AU away from the Sun. Let's substitute the formula, y=(x+4)/10, think 0, 0 plus 4 and divide by 10, and the answer we get is 0.4.

Then, the second circle is Venus, and the distance between Venus and the Sun is 0.7 astronomical units, and the formula is also substituted, y=(x+4)/10, x is 3, 3 plus 7, divided by 10, and the answer is exactly 0.7.

"The third circle is the earth, and the earth to the sun is 1 astronomical unit, and the number 6 is also substituted into the formula, and the result of 1 can also be obtained.

"Every number after that, substituting the formula, can calculate the distance between the eight planets and the sun.

"But there is only one number, and the calculated orbit has no planets, and this number is 24.

"And the orbit represented by 24 is the orbit of the asteroid belt."

0、3、6、12、24、48、96……

Each of these numbers represents one of the eight planets.

However, only on the number 24, there are no planets, and some are asteroid belts, what does this mean?

When everyone thought of this question, they suddenly felt a chill.
