"Lambda Orion, among the constellations of China, belongs to Alcedo One of the twenty-eight constellations. It is located above the middle of Betelgeuse and Betelgeuse, with an apparent magnitude of 3.39..."

Lang Tongguang continued to talk about astronomy: "The apparent magnitude is the level of a star visible to the naked eye. The smaller the value, the clearer you can see. The larger the value, the darker the star.

"In a clear and clear night sky, under normal circumstances, the visible magnitude of the human eye is 6.

"In other words, Lambda Orion is visible to the naked eye.

"However, the premise is that the night sky is clear and clear, the modern night sky is worse, so sometimes the stars of magnitude 3 are not easy to see.

"Let's continue to look at the computer-synthesized surface map of the Star Beast Mother Star. This is what the Star Beast Mother Star looked like a thousand years ago. Let's see what is special."

Fang Yuan carefully observed for a while, and replied: "There is no deep wind and big rift."

Lang Tongguang nodded with satisfaction, and said: "I remember your military research team has been to the Deep Wind Rift Valley, right? Yes, there is no Deep Wind Rift Valley on this planetary map.

"The reason why there is no Deep Wind Rift Valley in the picture is that it was not photographed, but that it did not exist. From this point, it can be seen that the Deep Wind Rift Valley did not exist a thousand years ago, but it was created later.

"As for the cause of the formation of the Deep Wind Rift Valley, if you are interested, you can check the information yourself. I won't talk about it here."

As for the reason for the formation of the Deep Wind Rift Valley, all military research students who had been to the Deep Wind Rift Valley knew about it.

The Deep Wind Rift Valley was caused by Luohu's halo-class aircraft that descended on civilization when it made an emergency landing.

Regarding this paragraph, there is still a secret level, and it has not been decrypted, so Lang Tongguang did not continue.

Next, Lang Tongguang explained some content about astrometry.

The get out of class was announced at 9:40 in the evening.

After class, Fang Yuan ran into He Minghao again on the steps in front of the building.

"You should be the reason why I joined the military scientific research class?" He Minghao took the initiative to speak.

"Well, I heard." Fang Yuan replied casually.

"Neither the future of the country nor the destiny of mankind should be placed in the hands of one person. You should understand this." He Minghao put his hands in his pockets and tried his best to express kindness, but there was still a sharp edge in his eyes.

"I'm just curious. When I went to the lecture last time, it seemed that someone said that they didn't like to join the military before entering the military scientific research class. Now this is ‘really fragrant’?" Fang Yuan grinned.

He Minghao frowned. Although he could hear that he was ridiculing, he couldn't be happy as the object of the ridicule.

Moreover, he did say that he didn't want to join the army, so he didn't enter the military research class.

Now I have entered the military research class again, and it is really fragrant indeed.

"The school leaders talked to me and selected them. Of course, I did agree..."

He Minghao looked up at the sky and sighed: "Sometimes life cannot be done according to my own wishes. In fact, joining the army is not my ideal state. But the elders and mentors think that the country needs me, so I have to shoulder this responsibility. ."

"Then I wish you success, sincerely." Fang Yuan smiled.

"Fair competition. I think our goals should be the same." He Minghao raised his fist.

Fang Yuan could see that the other party is already graduating from university and has mature thoughts. There is no problem in standpoint. Firstly, he is standing on the side of the country and then on the side of humanity.

In the main sense, the two sides are consistent.

As for competition, in the crisis era of the earth, whoever is stronger is the most correct choice.

Both sides gave a light punch, then each turned and left.

...

the next day.

The Planetary Defense Conference was held in the East China Sea.

The meeting place was at the Planetary Defense Council Building of Donghai City.

Two weeks ago, the Eastern Naval Academy of Sciences has released some evidence of the existence of meteorite civilization, and indicated that the meteorite civilization left a message.

This is the third civilization that mankind knows after encountering the star beast civilization and the soul of Palerce descended from the civilization.

Moreover, this civilization left a message.

This news is shocking news for all countries on the earth.

Therefore, in this planetary defense conference, almost all countries that can be named have come to participate.

The military research class was sitting in the northeast corner of the conference hall. There were 38 people in the class, most of whom came.

The five members of Fang Yuan's team formed a small group, and they had been talking quietly before the meeting.

Representatives from various countries entered the venue one after another.

At ten o'clock.

Fang Zhenguo went to the stage on behalf of the headquarters, took a document, put it on the podium, cleared his throat, and said: "Delegates, welcome to the East China Sea and participate in this planetary defense conference..."

After the opening remarks, representatives of other countries asked aloud: "Two weeks ago, you released the news that there was a civilization in the solar system. Is there any evidence?"

"Don't worry, we are holding this meeting today. This is what we are talking about. Please look at the big screen." Fang Zhenguo clicked on the remote control of the presentation.

A star map was released on the big screen, showing the solar system.

Regarding the star map of the solar system, everyone is very clear, basically it can be seen at a glance.

Fang Zhenguo shone a spot with a pointing ray, and said, "Everyone should be aware that this is the asteroid belt of the solar system. More than 600,000 asteroids have been discovered there. According to scientists’ estimates, all asteroids and cosmic dust add up. , Will exceed 20 billion.

"The meteorite civilization we announced is in the orbit of the asteroid."

After saying this, there was a discussion on the spot.

Since this meeting involved astronomy, delegations from various countries brought domestic astronomers.

After discussing for a while, the representative of the island country Koji Kawamura raised a question: "According to our astronomers, the total mass of all asteroids in the asteroid belt is not as large as that of the moon. It is impossible to breed a civilization in that location."

"What you know, would I not know?"

Fang Zhenguo glanced at him, blocked him back with one sentence, and then said: "As for the speculation about whether there are planets in the asteroid belt, I don't want to repeat it. I only talk about the key content of meteorite civilization.

"The message left by the meteorite civilization shows that they have encountered an attack from a higher civilization called the Purger civilization. This message was left over ten days before the civilization was destroyed.

"This [country novel www.yanjuexiangcun.com] information has a total of more than 20,000 words. It records the general condition of the meteorite civilization and the process of encountering the purge civilization attack, and finally leaves a warning.

"From the information left by the meteorite civilization, we can know that the meteorite civilization is a carbon-based civilization, living in an earth-like planet, and the orbit of this earth-like planet is near the asteroid belt."
