The Star National Space Agency (SASA) and the Ouzhou Space Agency (ESA) are the two major space exploration agencies.

It was the department that first noticed the phenomenon of "mysterious tracks".

After receiving the "emergency alert" issued by these two agencies, the Damao National Space Agency (RFSA), the Xia National Space Agency (XNSA), and the aerospace agencies of the island country, India San, Baxi and other countries also collectively paid attention to the mysterious trajectory in space.

They have pointed the scientific satellites in space at a certain direction.

They were all extremely surprised.

Scientists from all over the world are talking and putting forward a variety of opinions.

At first, the more mainstream view was the "comet theory".

"A comet that flies 800 kilometers per second and travels at a speed of nearly three million kilometers per hour? If it hits Blue Mercury, it will easily penetrate the crust of Blue Mercury like a sniper rifle bursting a watermelon, causing an earthquake or tsunami of more than 12 magnitude. ”

"Is a scene in the movie really going to happen in reality? Considering that the diameter of the mysterious object may exceed 100 meters, we have to send multiple space shuttles to the vicinity of the mysterious object, drill multiple holes in its surface, and then use nuclear bombs to blow the mysterious object into multiple pieces of debris no more than one meter in diameter to ensure the safety of Blue Mercury. ”

"But let's not say that we don't have a space shuttle available, and even if we do, we can't keep a relatively stationary space with a mysterious celestial body at a speed of 800 kilometers per second, and the plan of drilling holes and blasting on the surface is not feasible at all."

"The only way is to launch multiple nuclear missiles into space, aimed at the incoming mysterious celestial body, and blast the mysterious celestial body in a close-range explosion, and the explosion distance must be close enough, preferably the instant explosion of the collision, otherwise in the environment where there is no air medium in space, the power of the nuclear bomb explosion is only light and heat, no shock wave is generated, if the distance is too far, it will not be able to produce greater destructive power."

"But are there such space nuclear missiles in the nuclear arsenals of various countries? At the speed of a mysterious celestial body, there are only four days left to reach Blue Mercury, can missile experts from various countries have enough time to transform a ballistic missile-type intercontinental nuclear missile into a space nuclear missile? While ensuring sufficient accuracy, it can also be detonated at a very close range, can we, Blue Mercury, come up with such a space nuclear missile right away? And the number should be more than 10 pieces. ”

"What? Can't take it out for the time being? There are no such missiles in the arsenal of the Star Country? It takes at least ten days for a temporary renovation, and four days is simply not enough, what? Aren't you Star Country soldiers omnipotent in the movie, why did you suddenly drop the chain now? ”

"There is a way on our side of Mao, that is, to use a high-thrust carrier rocket to launch a nuclear bomb, place it in the necessary place of the mysterious celestial body, and use it as a 'space mine', as soon as the mysterious celestial body comes, the nuclear bomb will be detonated immediately."

"In addition, the national space station is about to be scrapped, but the remaining fuel in the space station is still sufficient, it is better to accurately adjust the orbit of the space station, and also let the space station close to the mysterious celestial body, as an obstruction object, it is best to let the two collide, and with the kinetic energy of the mysterious celestial body, even if it collides with an object the size of a basketball, it can burst out with 10,000 tons of equivalent energy, like a bird hitting an airplane, enough to smash the mysterious celestial body."

In a short period of time, scientists from Mao Guo thought of two better methods, which were simple and rude, and had high feasibility.

However, due to the presence of two astronauts stationed in the International Space Station, the second plan was rejected by the star country.

As for the first option, Mao can operate it on its own.

Two more days later.

After noticing the trajectory of the mysterious celestial body, there are obvious fine-tuning, deceleration and other fancy manipulations.

Scientists from all over the world were silent.

The strong sense of crisis has disappeared a lot, but the body trembling is even worse.

"God, I think there is a divine power at work that slows down the mysterious celestial body!" A scientist from the three countries of India suddenly said with some excitement.

"Judging from the sudden brightening of the mysterious celestial object, it should have slowed down on its own and activated some kind of deceleration device."

"In just ten hours, the speed has decreased by 400 kilometers per second, and its deceleration is more than 1 G, and it lasts so long that it cannot be a common chemical energy deceleration, it can only be a nuclear energy device."

"Every time its trajectory adjusts its position, it is the best adjustment point, connecting it into the shortest distance to Blue Mercury."

"I don't want to listen, I don't even want to say it! God said that human beings are the only intelligent race in the world, and all the heavens and stars exist to set off human beings, which can only be a miracle performed by the gods, and cannot be anything else. "Scientists in India and the three countries almost collapsed.

……

May 28th.

Images taken by the Harley telescope are transmitted back to the ground.

Almost all scientists are shaking with their hands and feet and on the verge of collapse.

"Fei You's paradox has been broken after all."

"If you can cross a distance of several light years or even dozens of light years and come to our galaxy, the other party's technological level is at least two hundred years ahead."

"What are their intentions? Friendly or hostile? Kindness or hostility? ”

"Are they here to make friends with us? How do we engage with them? ”

"We must prepare for an all-out war, their vanguard has come, and the next thing should be a war of conquest and rebellion, and the people of the Star Kingdom will defend their freedom to the death!"

A military representative of the Star Country clenched his fists and said angrily, Blue Mercury has the rules of Blue Mercury, and this is not a place where whoever comes can talk and talk.

……

May 29th.

In the command and control halls of many national space agencies, the pictures played on the big screen are focused on the relatively flat terrain in front of the moon star, a square shape like a long building block, a huge body, more than 500 meters of space objects, after approaching the moon star, slowly slowed down, reduced the altitude, and kicked up a burst of dust with a range of more than several square kilometers.

Even at night in the Eastern Hemisphere that day, some ordinary astronomy enthusiasts, operating astronomical telescopes with medium and high magnification focal lengths, could notice the abnormal scene on the surface of the moon and stars, and suddenly couldn't help but open their mouths wide.

……

Now.

The surface of the moon star, in a relatively flat basin terrain.

After all secondary engines are turned off.

Inside the bridge control room.

"Captain, the Scare-class transport ship 'Intrepid Bank' has completed landing, please give the next order."

"Send out combat squads to do a good job of guarding the surroundings; Send a team to collect some materials nearby to complete the task of replenishing the propulsion medium, and in addition, the signal officer pays attention to collecting information and paying attention to every move of the target planet. ”

The black-armored man stood with his hands in his hands.

"Yes!" A group of subordinates replied.

"Captain, the electromagnetic signal receiving device suddenly received a large number of signals, including prime codes and other communication information...... Those indigenous people are initiating exchanges. The signalman suddenly reported.

"Oh, when you heard that the Fright-class transport ship had arrived, were those natives frightened?"

The man in black armor said playfully.
