[September ~ October 23 of the Crisis Era, the wave of war]

In the 23rd year of the crisis era, the tide of open and secret battles between humans and betrayers has not stopped, but it has been relatively calm. During the year, mankind was completely unaware that Mars had been occupied, and it was not until September that a rash attack by the betrayers set off a new wave of struggle.

When the betrayer was also a human being before, and a member of human society, this generation happened to experience a pollution crisis, and the pollution crisis has always been a pain in human society, so much so that people deliberately avoid these topics in conversation. The nuclear contamination of that year led to acid rain and nuclear clouds, leaving humans to survive in underground cities, all of which were witnessed by all mankind. The mental blow brought about by the nuclear crisis has led some people down the wrong path, parting ways with human socialism, and turning it into a nightmare - "negative civilization"; It was precisely because of the lessons of the pollution crisis that the federal government put the "Starfield" team on trial for nuclear fusion reactions 23 years ago.

The Solar System Fleet's "Cosmos" detection system suddenly sounded an alarm, pushing the emergency atmosphere over and over again, each siren pushing the tension to another climax. There were five red-bordered buttons floating in the air, each numbered stating a different level of information, and the monitors opened each level to display the same content, each word a terrifying scream.

[The "City 1" space city was completely destroyed by an explosive attack, and it was preliminarily determined that the attack body was an antimatter bomb. It is predicted that no one in the explosion will be spared, with an optimistic forecast of 100 people surviving in the explosion area and a medium forecast of 200 survivors. According to incomplete statistics, 100 spacecraft leave the blast area every second, and about 200 people escape from the blast area and survive every second. 】

The monitor was shocked, hurriedly opened the communication network in the ship, called up a full-broadcast information window in the ship, and said: "Emergency notice: 'City 1' has been attacked, 'City 1' has been attacked, and the city is in the Jupiter region!" ”

The captain was resting when he suddenly heard the alarm, "Hurry." Wise man, the road to Jupiter. Locate 'No. 1' City. ”

The AI named Wise Man said, "Confirmed as the highest command authority." Targeted. The route has been planned. ”

The space carrier "Quantum Space" is flying towards Jupiter, followed by the space carrier "Oriental Oasis" and the "Expedition".

……

Inside the space city of the "Ark of Nature".

It is the second city on Jupiter's back, and the first is "City No. 1", all of which are in Jupiter's back. They used to exist in Jupiter's gravitational range, being Jupiter's moons, and then came to the far side of Jupiter and made a bunker home for almost a year.

In a residence on the "Ark of Nature", a piece of news is being broadcast on TV, the person watching TV is Ye Ying, next to Zhang Hongxing, the picture on the TV is switching continuously, and clear subtitles are placed below. The news is as follows:

……

[On September 4, 23 of the crisis, there was a violent explosion in the "City 1" space city, and according to the official statement, the attack body was determined to be an antimatter bomb, and the power of such weapons was comparable to that of a nuclear bomb, and it was even better. As early as three years ago, countries signed the "Treaty on the Prohibition of the Use of Antimaterial Weapons", and antimaterial weapons are also listed as prohibited weapons for war, so antimaterial weapons are currently only in the experimental stage and never appear in military strikes. Therefore, the attack on the space city should be the work of a "negative civilization". The damage caused by the military strike was enormous, and only one percent of the people in the space city survived. The video is as follows:......

The military strike has already caused serious panic among citizens, and the government is reassuring citizens in various places.

……

The ghost spaceship appeared at the exit of "City 1" Space City.

On the night of September 4, Crisis 23, a ghost spaceship suddenly appeared at the exit of the city, emitting a bright light. It flashed regularly for about a minute, and then the city government sent a battleship to intercept it. Encountered, the following is the description of the warrior Luo Wei:

Reporter: Soldier Luo Wei, what did you encounter after the fleet chase?

Luo Wei: At that time, it seemed that they encountered a fleet, which is what you call the ghost fleet, and the two sides exchanged fire for about an hour, and then the city defense unit activated the high-power particle beam cannon, destroying one of the more combat-effective ships, and then they retreated.

Reporter: You ...... at the time It's a kind of ...... in the face of war What kind of mood?

Luo Wei: I was a little nervous at first, but then I was not nervous. All good.

Reporter: Do you feel proud of the battlefield in the human world?

Luo Wei: Hmm...... Particularly proud. We, the city defense soldiers, must go to the soup for the people!

Reporter (applause): Thank you for your cooperation with our interview!

Many people are curious about the ghost spaceship flash event. Some people think that it is the deadly light of the previous UFO, and they think that this is the prototype of the UFO. Expert: There may be some kind of signal. 】

"Look at this. Look at something else, basketball CBA. Zhang Hongxing said, "I don't even want to go back to Mars, the low gravity of Mars is uncomfortable, it's better to be in the space city, the space city is man-made after all, and the gravity can be adjusted at will, as long as the city rotates." ”

"Look back at your house." Ye Ying said, "...... Oh yes, how do humans create a gravitational environment. ”

"They wanted Space City to rotate so that there would be a centrifugal force, just right to simulate the gravitational field effect. You see, it's a barrel, we're inside the inner wall, it's spinning, and we're sucked in tightly. As long as the speed is fast enough, it can simulate the gravity of the earth in the past. Zhang Hongxing picked up a water glass, pointed at it and said, "Isn't this the physics of the third year of junior high school, have you forgotten it?" ”

"Uh, hehe. That flashing video on the news, I think it might be Morse code. ”

“Maybe.”

"I'll do the math, this is...... Turn it back, the video goes back, okay, this light, long ...... Short ......" Ye Ying looked at the TV screen, holding scratch paper and writing.

"I thought you didn't understand anything, but I didn't expect you to understand this." Zhang Hongxing said.

"I'm a signal professional, why don't you understand?!" Ye Ying replied.

Half a day.

"Ah...... This one...... Oh, why is it dark, is there a power outage? Ye Ying shouted in the suddenly dark room.

“SOS…… MARS.” Ye Ying whispered, "Secret! Shocking secret! After someone has fixed the electricity, I will write my thesis. ”

"Crazy you."

……

On October 1, the fleet had just arrived at Jupiter. From Saturn, it took about fifteen astronomical units (the distance from the Earth to the Sun is one astronomical unit) to Jupiter. It was expected to arrive on September 10, but due to various reasons, it was delayed a little, so it only arrived on October 1.

"What's going on, why is it only here now?!"

'Report!' During the voyage of the Quantum Space spacecraft, the components of the engine nuclear fusion reactor maglev device deteriorated, and in order to prevent the high-temperature nuclear reaction from damaging the hull, it was repaired by traditional methods, so it dragged the whole fleet for 20 days. ”

"Hmm...... If the repair takes up to eight days with the usual procedure, how can it be delayed for 20 days? ”

"Report to Captain Dongyang, I don't know why."

Dongyang Qiyue waved his hand, and the guards went down. Suddenly, an information window caught her attention.

[Compiled electromagnetic wave information has been detected.] , the emitter source is determined to be Mars]

"That could only have been sent by a Martian human." Dongyang glanced at the planetary orbit map at this time, and saw that Mars was closest to the fleet at this time, and moved towards the same line as the fleet, "Why Mars?" ”

The AI did not give a reply. At this time, Dongyang was the only one thinking about this problem, and behind him was the cold cosmic starry sky.
