As early as the prehistoric civilization, humans brought back the first lunar soil from the moon. It was a composition rich in various metallic elements, which seemed to be a great fortune at the time. These can be applied to human exploration in the universe.

Over the next few hundred years, everything that could be mined on the surface of the moon was transported back to Earth. And thus started the fifth industrial revolution in human history, also known as the space industrial revolution.

As a product of modern industry, limestone has been fully utilized in all walks of life under the leadership of the coalition government. Whether it is used in metal refining in a vacuum environment, alloy processing, etc., it has a wide range of functions. Of course, these are limited to the military, and have not yet been popularized for commercial and civilian use.

The conference room of the Galileo Research Center.

Greystone was confirmed again.

"Don't underestimate two pieces of greystone, enough to transform the Galileo." Zuo Lan said excitedly. This is a fact that she and Lin Yu have confirmed.

One room of greystone. Zhou Kun's mind flashed in an instant, these resources are a pity. Although I want to take some more, it will be a big problem.

Lin Yu said with some excitement, "The shell of the Deep Space Fortress is using these gray stones. Ordinary alloys or other metal elements are quickly alienated by the generated magnetic field waves under the action of anti-gravity, affecting the physical properties. With Greystone, the Galileo is enough to be the best warship. ”

Xu Suyu didn't understand these very well, but instinctively excited because of Zhou Kun's excitement. "Why would such an important strategic material appear on an ordinary spaceship?"

This is also everyone's question, Zhou Kun glanced at the more than ten core personnel present, "This matter is over, top secret." ”

At the end of the meeting, Liu Shujuan found Zhou Kun, "Zuo Lan's recent mood is not quite right, since the beginning of the school to visit Du Tao, the whole person is restless. ”

Zhou Kun didn't know anything about this, "I also went to see Du Tao once before, and I heard from the inspection doctor that the situation is getting better and he is expected to wake up early." ”

Liu Shujuan sighed and frowned, some words were difficult to say. This stupid man's emotional intelligence is too low, I originally thought that he would understand this mentions, but now it seems that it is better not to say it.

"I mean, since Valentine's Day, she's suddenly like she's changed."

Valentine’s Day? What happened to her on Valentine's Day? Zhou Kun didn't understand, and the incomprehension in his heart was directly expressed on his face.

Liu Shujuan found that it was easy to talk to Zhou Kun about her feelings.

"In the second half of the first year, there will be three months to go to other schools, what are your plans?"

Zhou Kun shook his head, "We Galileo will definitely act together, and I will bring this up with the school." ”

"It's about career choices, everyone's situation is different, and of course everyone's choices are different, how can it be possible." Liu Shujuan wanted to persuade Zhou Kun.

"Oh."

"Your career choice cannot be anything other than the captain, and the corresponding colleges are only the National Defense University of the United Government and the Military Science and Technology College." Liu Shujuan said seriously, "These two are military academies and belong directly to several major fleets. The National Defense University is more inclined to the comprehensive strength of individuals, and the Military Science and Technology Academy emphasizes military capabilities. ”

Zhou Kun only understood a little at this time, and he was a little grateful in his heart, his current situation seemed to be more delicate, and he might need the nod of the coalition government to which institution to go to. However, judging from Liu Shujuan's introduction, it seems that she is looking forward to going to the Military Science and Technology Academy.

"What about you? Where are you going? Zhou Kun couldn't help but ask. As the only two reserve candidates for captain on the Galileo, Liu Shujuan's choice is also very important to herself.

"Military Science and Technology Academy." Liu Shujuan said generously.

"Hmm......" Zhou Kun touched his chin and looked up.

……

The Camry spacecraft incident finally died down under the consultation of Zhang Yanming and Zhou Feng, and the two sides reached a tacit understanding based on the principle of exchange of interests. At Zhang Jingjing's strong request, not holding Zhou Kun accountable was one of the contents of the negotiations.

Zhou Feng in turn severely reprimanded his precious son, "You rabbit cub, make trouble for Lao Tzu all day long." If Lao Tzu steps down, what are you going to do? ”

Zhou Heng saw that the old man suddenly changed the direction of the wind, so he inquired left and right, "I see." That's fine. Zhou Kun walked and looked, my father promised to let you go, but I didn't agree. ”

Although Zhou Feng knew his son's temperament, he couldn't always be by his side all day long, so he arranged for someone to send this living treasure back to school.

Zhang Jingjing and Zhang Ji, brother and sister, tried to find Zhou Kun several times to express their gratitude, but they all returned in vain.

"Where does he run all day long?" Zhang Jingjing was a little curious, he was awarded the rank of second lieutenant about the same size as himself, and the school held him as a treasure, what kind of person was he?

Zhang Ji knew his sister's thoughts, and he didn't persuade him much. So the brother and sister made an appointment to visit Principal Sima De.

"Hello, Headmaster. ......" Zhang Jingjing generously talked about the reason, and Principal Sima De said in his heart, did this kid have shit luck? The daughter of the branch president of the Chamber of Commerce seems to have a good impression of him.

"The Zhou Kun you mentioned is the captain of the Galileo training ship." Sima De said, "He doesn't usually live in the dormitory, and this is also my fault, since our school gave him the Galileo training ship, he has been there most of the time." ”

"Don't worry. In a while, the exchange student activity will be coming, and I estimate that he is very likely to choose the National Defense University. Then you'll see each other again. Sima De said in his heart, with this kid's virtue, there is a chance that it will be the world's top military academy. Besides, he knows a fart, and he doesn't have to be arranged by the school.

Zhang Jingjing and Zhang Jisi's brothers and sisters were in a good mood when they heard this, and asked again and again, "Principal Sima, you must arrange for Zhou Kun to come to our school." My family and school are urging me to go back to school, so I will leave. ”

Watching the brother and sister leave, Principal Sima De laughed a few times, Zhang Yanming, you are going to bleed heavily this time. Thinking of this, Sima De personally contacted Zhang Yanming.

"Lao Zhang, our Zhou Kun saved your precious son and daughter, you don't mean it at all?"

"Huh? Principal Sima. Thank you so much, I am arranging to go to your school to thank you, but I didn't expect you to get in touch in advance. You also know that the Chamber of Commerce is busy investing in the moon right now. ”

The two old foxes were idle.

Zhou Kun naturally didn't know this. At this moment, his attention was focused on the exchange students. Which school to go to first depends on your own positioning, if it is only limited to military wars, it is a bit narrow. If you really have to choose, the National Defense University seems to be more suitable for you.
