Ten years later.

Spring 2085.

In the high mountains of southwest China, a radio telescope with an area the size of 30 standard football fields is located here.

The "dirty bomb" incident more than 50 years ago caused a large area of ​​pollution, but this is not within the pollution area.

Therefore, as one of the few high-sensitivity, large-scale radio telescopes on the earth, the "Sky Eye" has been renovated, expanded, and replaced with reflecting units several times, and it is still going strong today, half a century later.

Not only that, its scientific research work is still running in an orderly manner.

Not far from the huge reflecting surface, there are several white buildings. This is the main control room of "Sky Eye". Although it is late at night, the main control room is still brightly lit.

"Director Yan, data related to the interstellar clouds observed by the beam receiver and the high-density nanohertz gravitational waves in related areas are being transmitted.

It’s estimated that it will take another 10 minutes!”

"Well, pay special attention to Fermi high-energy radio waves and nanohertz gravitational waves. These two are the data that Academician Yan has focused on.

It is the most obvious trajectory signal left by a large interstellar battleship after its jump voyage."

"clear!"

The young engineer's eyes have been staring at the data on the quad screen in front of him. The huge screen in front of the main control room is simultaneously updating the deep space environment image that has been transformed by the system...

"The receiver is automatically distinguishing the type of received signal, the system resolution is 3.8 mm, and the data is being imported into the radiation model.

Oscillator mode receiver frequency coverage, 70-3000mhz band!

The band data has been imported successfully and will be matched with the previously determined parameters. The matching is completed with a matching rate of 99.99%. It is confirmed to be the trajectory signal left by the star battleship group!"

As the analysis of relevant data was completed, the yellow warning lights on both sides of the main control room also lit up, and its "wuwu" sound once again attracted the attention of other engineers.

Everyone put down what they were doing and collectively looked at where Mr. Yan and the others were.

Those warning lights were installed later, specifically to detect the navigation trajectory of the mechanical civilization fleet group, after ten years of normal operation.

Everyone has become accustomed to his presence.

Even so, it still attracts the attention of most people every time it sounds. They know that this means that the huge alien fleet sailing towards the solar system is coming towards them along a fixed route...

"Upload the data to Planetary Defense Command immediately!"

"yes!"

The young engineer immediately started operating on the keyboard. Looking at the rapidly advancing transmission progress bar, the engineer turned his head.

"General Engineer Yan, I have always had a question in my mind. I don't know whether I should ask it."

"Xiao Lin, tell me!"

"We have been observing this track for ten years. In fact, anyone who knows a little bit about astronomical observation knows that in the universe, seeing and seeing clearly are completely different things.

Take our celestial eye as an example. It can even observe galaxies millions of light-years away, but it can only be seen because of time and signal transmission speed issues.

In fact, we are seeing interstellar data from millions of light years ago. Now, some of the observed objects no longer even exist.

Specific to the fleet of mechanical civilization, we can only observe the wake of its sailing, which was a long, long time ago. Does this still have reference value for our current military deployment?

What I mean is, maybe mechanical civilization will arrive in the solar system tomorrow, but we are still looking at its trajectory hundreds of years ago!

Although I don't understand military affairs, I also know and can clearly see that immediacy is an important reference condition for military deployment.

To see clearly, radio telescopes and optical telescopes are not enough. What they really need is observation data from deep space exploration early warning devices.

Moreover, deep space detectors are all array-type, and they are also equipped with relay base stations. Quantum transmission ignores the distance factor.

If we spread detectors throughout the galaxy, we can truly see any external invasion."

After speaking, the young scientist shook his head in confusion. It was not that he was emotional about his current work, but he was worried that it would delay the war!

"Of course there are deep space detectors, but have you considered how much effort is needed to achieve the level you mentioned? How many detector arrays are needed?

This is equivalent to materializing a distance of tens or hundreds of light years. Such a cosmic-level project may require a more advanced civilization to accomplish.

The data we have transmitted over the years is actually very important because they are all indispensable correction parameters.

Only when that prediction model reaches 100% accuracy can the Black Armored Legion accurately determine the interstellar airspace where the opponent's huge fleet may appear based on it.

However,,,perhaps these data will not be needed in the future, because the interstellar coordinates of this observation are already close enough to the solar system.

Going forward, we should be able to see the deep space detection array directly, right?"

After speaking, Chief Engineer Yan looked at the progress bar that had been transferred. He didn't know how that leader-like figure would react after seeing the data...

...

When the detection data of the "Sky Eye" was transmitted here at the Mars Research Institute, Chu Ge, Yan Tianhao, and Commander Wang were all here. After receiving the information, Yan Tianhao immediately entered the radiation model.

Five minutes later, Yan Tianhao turned his head and nodded vigorously towards Chu Ge.

"Okay, regarding the window period, our verification period is a bit long, but after the last 10 model predictions and actual route verification, we have confirmed its reliability.

Tianhao, let [Huoyi] supercomputer calculate the most advantageous ambush coordinates!"

After Chu Ge finished speaking, Yan Tianhao immediately took action. He began to import the coordinate points of the Black Armored Legion's deep space detectors and the positions of the early warning arrays set up by the reconnaissance ships into the supercomputing server...

"It's out! M15 star cluster!" Three minutes later, Yan Tianhao shouted loudly.

"M15? Why is it so familiar?" Commander Wang muttered again.

"The M15 cluster, also known as the Pegasus dwarf galaxy, is a satellite galaxy of the local galaxy group M31 Andromeda. You should really be familiar with it.

The tantalum star is one of this dwarf galaxies, but this dwarf galaxy is not on the ecliptic plane, so its distance is not as far away from us as the main galaxy it orbits."

After Yan Tianhao finished the introduction, he looked at Chu Ge. The latter remained silent and seemed to be making his final decision.

"Kane, in my name, issue a message to all members of the Planetary Defense Council and the headquarters of the Black Armored Corps, saying that the combined fleet will begin to assemble tomorrow, March 11, 2085.

In addition, in order to commemorate this most important interstellar battle in human history, let us use the most popular "Battle of the New Age" to define this interstellar war.

Since it is a new era, without abolishing the original AD calendar for the time being, a new calendar method will be used to herald the restart of all human affairs and sail away!
Chapter completed!
