After 330 million years of destruction of life on Venus, another 330 million years later, Mars.

"Ladies and gentlemen, insert a piece of the latest news, according to the research of the chief scientist of the National Academy of Sciences, the geomagnetic field of Mars is disappearing, the reason is from the core of Mars, and the direct consequence of the disappearance of the geomagnetic field is the escape of the atmosphere, in layman's terms, Mars is running out of oxygen!" The first set of channels reported by the famous news announcer Xiaoli.

……

The eastern part of Mars, the twilight home of the Yan country.

The head of the Twilight family, Twilight: "There is a war every day, from the Kingdom of Jin to the Kingdom of Wood, and now it has bypassed the country of water and fought to the country of fire." The Yan Country is powerful, but after all, it is a small country, and the Fire Country is a big country, and one of the other people's states is larger than ours. ”

Twilight's wife, Huo Sanghua, said: "Husband, don't talk about it, watch the news." Concerned about what they do, anyway, they don't deduct our salaries, and we can give some advice on the children's elective courses at Harbin Silver Academy. ”

Twilight, the child of twilight, says, "Mom! I'm almost thirty, thirty, okay?! ”

In the hallway outside the living room, Twilight and her son Twilight get together.

"Is the door closed?" Twilight asked.

"It's closed, I said Dad, isn't this lock a dead lock, and it can't be opened even if you have a key." Twilight replies.

"Hehe, I'm afraid of your mother when I'm in love, I'm used to it. Okay, you've chosen your class, right? Twilight asked again.

"Well, it's chosen. I chose three courses: astronomy, physics, and philosophy, and I was interested in all three, and I said Dad, you also saw the news just now, Mars is almost unsuitable for human habitation. Twilight replied again.

"You believe Morningstar's words?!" Twilight asked.

"Why don't you believe it, he won the Martian Nobel Prize, or twice the Prize in Physics, the Astronomy Prize in 05, and the scientists in big countries like the Fire Country and the Gold Country who have not yet won the Mars Nobel Prize?" Twilight finally replied with reason.

After talking to her father, Twilight, who is also an astronomer at the National Academy of Sciences in Yanguo, walks on the sidewalk of the city road to Hayin Academy. Twilight's family is a family of three, his father's personality is between free and rigorous, and his mother's Huo Sanghua personality is more traditional and cares for the family, while Twilight's personality inherits his father's free and easy, rigorous, not the kind in the middle, and a little tradition, as for the Gu family, as long as it doesn't count the kind of taking out a lot of things at home and giving them away, it's still very family-friendly, and in addition, Twilight also summed up two words for himself: serious. Twilight's relationship with Morning Star is like that between Faraday and his mentor, Morning Star is Twilight's student, but he goes further in astronomy than his mentor Twilight, and has a talent for physics, so Twilight's psyche has a strange sour precipitation.

Twilight, who has asked me who I am since I was a child, has been exposed to special disciplines to study and discuss this aspect when I grew up, so I chose philosophy, astronomy, one is to be touched by my father Twilight and worship his idol Morning Star, that is just a miscellaneous work in the Academy of Sciences, Morning Star has now become the youngest president of the Yanguo Academy of Sciences, and his 'two gravity' papers have been partially confirmed, causing a great sensation on Mars.

'The first gravitational force, in which matter is trapped when it is dispersed on its side, moves closer to the center, forming an internal gravitational force, and when the planet rotates, it forms an external gravitational force. The second gravitational force, also known as static gravity, is the gravitational force formed after gravity compresses space. ’

Twilight thought about the two gravitational forces as she walked, especially the first gravitational force, which raised the war to a higher level, and the distance bullets and spinning bullets produced by the national arsenal were stronger than any existing machine gun bullets, which was also the reason why the small country of Yan dared to attack the country of gold and the country of fire. The second gravitational pull is mainly used in aerospace, and the Mayflower country is the best done of all the countries on Mars. Twilight instead focuses on the second gravitational force, which has little practical value, and dreams of using it to create ordinary warships that can fly over long distances.

A dragon bird suddenly fell from the sky and died, and Twilight picked it up from his heel and put it on the palm of his hand to watch, 'The color is bright, and there is still residual warmth, and it dies of exhaustion.' This is a simple conclusion that Twilight's mother, Mulberry, is a doctor.

Looking up at the sky, there was another dragon bird flying towards the sky. He knew that he was born with the habit of flying his head up and flying high in the sky, but he had not flown too high and died of exhaustion.

'Why are you still flying?!' ’

The dragon bird watching it was the size of an ant, and there were smaller and smaller postures, indicating that it was still struggling upwards until 'bang! It fell like a stone to the ground. Twilight picked it up again, and the more he looked at it, the more strange it became, until he remembered the report of Xiaoli, the famous announcer of the first set of channels today, that the Martian atmosphere has escaped, and Mars is running out of oxygen!

The two dragon birds did not die because of exhaustion, but because they accelerated their movement in the case of lack of oxygen, so they died of lack of oxygen! 'Hum', Twilight also has a huge death threat, he doesn't feel unaware, he also has a feeling of not breathing, he knows that this is not a mental effect, just like a certain day in autumn and winter, it is really entering a certain period.

"There are spies in the Fire Country. Don't run! ”

From afar, I heard that someone had arrested a spy from the Fire Country. Now that the Yan Kingdom and the Fire Country are at war, it is really possible to see the spies of the enemy country chasing after the city streets of the Yan Kingdom.

Twilight knew she had to stay away, he was still a student at the Ha Yin Academy, and he didn't dare to touch such a deadly thing.

"That young man, did you just see the person on your phone passing by?"

Suddenly, Twilight is stopped by someone, and he has to turn around because he has his back to the person and wants to see the photo on his phone. At this time, the person who called him knew that Twilight, who was stopped by him, was a student of Ha Yin Academy.

The person on the phone had a mogill beard and a beret on his head, and he could see that he was quite handsome when he looked closely, and after a few more perfunctory glances, Twilight said, "No, I haven't seen it." "This is the first time that the police have caught a spy, and the other party still has a gun in his hand.

The man who asked him looked at the corner behind him, and then at Twilight's full body in a silver school uniform, Twilight's demeanor really didn't look like a lie, so he politely interrupted him, and turned to catch the spy.

He stayed there for a minute, and asked him that the man was different from the policeman he usually met on the street, although he was also wearing a police uniform, he always felt that something was wrong, and he looked fierce, not like asking ordinary citizens, especially when he pointed his pistol at Twilight.

"Thank you, students of Harbin Academy!"

"Ahh!!h

Twilight, who was in a state of shock, was half frightened to death, not caring what the other person meant.

"Are you...... You're a spy! "I've just seen the photo, which can also be said to be an instant photo, how can I not recognize it.

"Don't scream!" The other party is anxious, and immediately wraps his arms around Twilight's body, then frees up one hand to cover his mouth, and continues, "I'm not a spy!" He is, I'm a native of the Yan Country, and I'm also a scientist, he wants to capture me in the Fire Country and do research for them! ”
