The Singapore Aerospace Administration (SASA) and the European Space Agency (ESA), the two major space exploration agencies.

It was the first department to notice the "mysterious tracks" phenomenon.

After receiving the "emergency alerts" issued by the two agencies, the Republic of Mauritius Space Agency (RFSA), the Xia National Space Agency (XNSA), as well as the space agencies of the island countries, India, Brazil and other countries, also collectively paid attention to the mysterious track in space.

They all aimed their scientific satellites in space at a certain direction.

They were all extremely surprised.

Scientists from all over the world are discussing this and putting forward various opinions.

The mainstream view at the beginning was the "comet theory".

"A comet traveling at 800 kilometers per second, nearly three million kilometers per hour? If it hits Blue Mercury, it would easily penetrate the planet's crust like a sniper rifle popping a watermelon, causing an earthquake or tsunami exceeding magnitude 12."

"Will the scene in the movie really happen in real life? Considering that the diameter of the mysterious celestial body may be over 100 meters, we will have to send multiple space shuttles to the vicinity of the mysterious celestial body, drill multiple holes in its surface, and then use nuclear bombs to blow the mysterious celestial body into fragments no larger than one meter in diameter to ensure the safety of Blue Mercury."

"But putting aside the fact that we no longer have a usable space shuttle, even if we did, we wouldn't be able to maintain relative stability with a mysterious celestial body at 800 kilometers per second. Drilling and blasting on the surface simply isn't feasible."

"The only way is to launch multiple nuclear missiles into space, aiming them at the incoming mysterious celestial body and shattering it with a close-range explosion. The explosion must be close enough, ideally at the moment of impact. Otherwise, in the absence of air in space, the nuclear bomb's detonation will only produce light and heat, without a shock wave. If the distance is too far, it won't be able to produce significant destructive power."

"But do the nuclear arsenals of other countries have such space nuclear missiles? At the speed of the mysterious celestial body, it will reach Blue Mercury in four days. Do the missile experts of various countries have enough time to transform ballistic intercontinental nuclear missiles into space nuclear missiles? While ensuring sufficient accuracy, can they also detonate at extremely close range? Can we on Blue Mercury immediately produce such space nuclear missiles? And ideally, at least ten of them?"

"What? Can't get it out right now? Even the Star Country doesn't have such a missile in its missile arsenal? Temporary modification would take at least ten days, four days is not enough. What? Aren't your Star Country soldiers omnipotent in the movies? Why are they suddenly failing now?"

"We in Mao Country do have a solution. That's to use a high-thrust carrier rocket to launch a nuclear bomb and place it where the mysterious celestial body must pass. It will act as a 'space mine' and detonate the nuclear bomb as soon as the mysterious celestial body approaches."

"Also, the national space station is about to be scrapped, but it still has plenty of fuel. We should precisely adjust the station's orbit so it's close to where the mysterious celestial body must pass. As an obstructing object, it would be best to cause a collision between the two. Given the mysterious celestial body's kinetic energy, even a collision with an object the size of a basketball would unleash a force equivalent to tens of thousands of tons, like a bird hitting an airplane—enough to shatter the mysterious celestial body."

In a short period of time, scientists from the Mao country came up with two better methods, which were simple, crude and highly feasible.

However, since there are two Singaporean astronauts stationed in the International Space Station, the second option was rejected by Singapore.

As for the first option, Mao Guo can do it himself.

Two more days passed.

After noticing the movement trajectory of the mysterious celestial body, there were obvious fine-tuning, deceleration and other fancy operations.

Scientists from all over the world remained silent.

The strong sense of crisis was relieved a lot, but my body was shaking even more violently.

"God, I think God's power is at work, slowing down the mysterious celestial body!" A scientist from India suddenly said excitedly.

"Judging from the sudden brightening of the mysterious celestial body, it must have slowed down on its own, activating some kind of deceleration device."

"In just ten hours, the speed dropped by 400 kilometers per second. The deceleration exceeded 1G, and it lasted for such a long time. It couldn't have been a common chemical deceleration, it could only have been a nuclear power device."

"Every time its trajectory adjusts its position, it becomes the optimal adjustment point, forming the shortest route to Blue Mercury."

"I don't want to hear it anymore. Don't say anything! God said that humans are the only intelligent race in the world, and all the stars in the sky exist to set off humans. This can only be a miracle performed by God, it can't be anything else." The scientists from the three Indian countries almost collapsed.

…

May 28th.

The pictures taken by the Halley telescope were transmitted back to the ground.

Almost all scientists were trembling and on the verge of collapse.

"Feuillet's paradox has finally been broken."

"To be able to cross a distance of several or even dozens of light years and reach our galaxy, their technological level must be at least two hundred years ahead."

"What are their intentions? Friendly or hostile? Kind or hostile?"

"Are they here to make friends with us? How should we approach them?"

"We must prepare for all-out war. Their vanguard has already arrived. What follows will be a war of conquest and resistance. The people of Singapore will defend freedom to the death!"

A military representative from Star Country clenched his fist and said angrily that Blue Mercury has its own rules and this is not a place where anyone can keep their word.

…

May 29th.

In the command and control rooms of many national space agencies, the images played on the big screens are now focused on the relatively flat terrain in front of the moon. A square-shaped space object, like a long building block, with a huge body and a length of more than 500 meters, approaches the moon, slowly slows down, lowers its altitude, and stirs up a cloud of dust covering an area of ​​more than several square kilometers.

Even on that night in the Eastern Hemisphere, some ordinary astronomy enthusiasts, operating astronomical telescopes with medium to high magnification focal lengths, noticed the unusual sights on the surface of the moon and stars, and could not help but open their mouths in amazement.

…

now.

On the surface of the moon, in a relatively flat basin.

After all auxiliary engines are shut down.

Inside the bridge control room.

"Captain, the Fright-class transport ship 'Dreadnought Bank' has completed landing. Please issue the next level of instructions."

"Send out a combat team to provide security around the area. Send out a work team to gather nearby materials and complete the propulsion medium supply mission. Also, the signal officer should gather information and monitor the target planet's movements."

The man in black armor stood with his hands behind his back.

"Yes!" replied the subordinates.

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

"Oh, upon learning of the arrival of the Fright-class transport, were the natives frightened?"

The man in black armor said with some amusement.
