12 years old lacks 2, what does this mean exactly? Zhou Kun has been worried about this in recent days. My father was a programmer and couldn't have written anything that didn't make sense, and the only explanation for doing so was to keep it secret.

12 years old? This should be the first suspicion. Missing 2 should be the second. Zhou Kun judged.

So next, Zhou Kun frantically searched for topics related to the age of 12. Mother Sun Ying was very happy, and she recalled the days when she was 12 years old with Zhou Kun, but after thinking about it for a long time, there was nothing special, nothing more than the life of junior high school.

The new students aboard Galileo gradually began to get used to this kind of life after contacting their families. Zuo Lan and Liu Shujuan have a full schedule of time every day, and everyone knows why they do it. Occasionally, the freshmen take a half-day vacation and go out to buy some things, but fortunately, there are still a lot of things on the Galileo, plus Xu Suyu has sponsored some more, which is enough to support more than 3 months.

Behind the scenes, the freshmen began to take Xu Suyu for granted that she was the captain's wife, and of course, they only dared to talk behind their backs, who knew what the ending would be if Zhou Kun knew. Pan Wei got started quickly, everything was done in an orderly manner, Zuo Lan thought of Du Tao, and inevitably felt some bitterness in his heart.

On this day, Zhou Kun suddenly wanted to go back to his original high school to find inspiration, so he took Xu Suyu to his alma mater, and the school was on vacation along the way, and there was no obstruction, and the two easily came to the astronomy room of Tianyi Middle School.

It's business as usual. Tianyi Middle School has not changed much because of the special case of Zhou Kun's test-free admission, and in the final analysis, Zhou Kun's quota has nothing to do with the school.

Xu Suyu's eyes lit up as she looked at it, and she kept chattering. Zhou Kun had to explain patiently one by one. The girl's curiosity made him feel unusually heavy and tired.

In the astronomical room, two people take turns looking at celestial objects, some of which move very fast, some very slowly. Zhou Kun patiently explained each planet, which was what he was most interested in.

"The earth revolves around the sun for one year."

"The farthest orbit of Uranus is about 84 years, and Saturn is 29 years."

Xu Suyu was a little puzzled, "Why does it take so long?" ”

"Because they're far from the sun, relatively speaking, maybe because they're a little more massive."

"What about Jupiter?"

"Jupiter 12 years." Zhou Kun said casually.

Wait, 12 years? 12 years old? In fact, Jupiter's revolution is less than 12 years.

"I see, haha!! Su Yu, I understand. Zhou Kun shouted happily.

"How happy are you?"

"I can't say it yet. I'll tell you later. Zhou Kun smiled and said to Xu Suyu, Dad should be going to Jupiter, but where exactly is he going? Missing 2, just referring to Jupiter itself? Or a moon of Jupiter? Europa 2.

Although Xu Suyu was very unhappy that Zhou Kun kept it a secret from him, he could understand it to some extent, being with the person he liked was like this, and he would be happy when he saw him.

The two of them were tired of being in the astronomical room for a long time, and finally reluctantly went back.

Zhou Kun, who arrived home, hurried to the battleship Galileo again. After supporting everyone, Zhou Kun turned on the three-dimensional combat display screen, and the coordinates were transferred to the universe. The largest one, Jupiter.

Europa, one of Jupiter's farthest moons, is said to have been discovered by Galileo during the prehistoric civilization, also known as Galileo's moons. Because of its proper distance from Jupiter, it has long been considered a habitable planet by humans. Entering the ephemeris era, Europa has undergone significant changes, the weakening of the sun, Jupiter's original separate system is more perfect, although there is a lack of light, but human beings still believe that the atmosphere and a large amount of water are suitable for human survival, especially after the development of the artificial sun, this possibility is stronger. Compared with the exploration of the stars, some humans believe that Ganymede is more worthy of exploration and transformation.

Zhou Kun muttered to himself as he watched all this, and he was deeply sure that this was the meaning of the characters left by his father on the last page of the notebook. Not bad, decrypted!

This day happens to be the last day of the 38th year of the ephemeris.

The freshmen of the Galileo clearly felt Zhou Kun's emotions, although they didn't know why, but emotions were contagious, so everyone became very happy. Zuo Lan muttered a little, but she didn't know what she was talking about.

Liu Shujuan's eyes flickered, as if she had guessed something, she bit her lip and did not speak.

With two months to go until the New Year, each new student is given a few days to wander around the strange city and send a message to his family when he is free.

The days went on like this.

But Zhou Kun never appeared again. Although Sun Ying didn't say anything, her heart was very open, and this kid had figured out something nine times out of ten.

----------------

Lao Qi and Li Changgen were a little helpless, governing the city was not their specialty, but the minister didn't seem to have the intention of sending someone else to take over. The coalition government's sneaks didn't pay much attention to the fact that the Ministry of Emergency Management had taken over several cities, and the result was a good thing for them.

"The minister seems to be eating very accurately." Lao Qi sighed, "But it's us who are suffering now." ”

"General Qi, it's true. Recently, some low-ranking officers have come to me every day to complain, and they are good at solving problems, and governing cities is not their strong point. You said you wanted something professional, and they all did it, but now. Li Changgen sighed helplessly.

Two people with big eyes and small eyes.

There are currently three cities included in the Ministry of Emergency Affairs, and the office is set up at coordinates latitude 31 and longitude 120. As a result, the city has more resources, which means that people in the city are better off.

On the streets, because of the appearance of the new life of the Galileo, it gradually gained some popularity, and people began to be willing to walk on the streets.

The Ministry of Emergencies even procured some New Year's necessities, adding a touch of joy to the city.

-------------------

Xu Suyu grinded from Sun Ying to Zhou Kun's residence and touched it alone.

"Okay, what are you doing behind my back?" Xu Suyu was a little sullen and didn't see anyone for three days.

After entering the house, he didn't talk nonsense, Xu Suyu quickly walked around Zhou Kun's house, but found nothing. Zhou Kun was a little puzzled, what's wrong? Did you get sick?

"Say, what are you doing all these days?" Xu Suyu asked with a serious face.

Zhou Kun hurriedly replied, "It's nothing, just look at the nebula map and study it." ”

"Really?"

"Of course."

"Well, I'll take you for now. It's almost the New Year, and you have to prepare me a New Year's gift. ”

Zhou Kun looked confused, New Year's gift? I've never heard of this stubble.

Xu Suyu saw Zhou Kun's expression and felt displeasure in his heart, turned his head and left.

PS First Update. It's finally awkward. Finally there is an answer.
