A certain number of frigates are arranged on both wings and the rear side of the Expeditionary Fleet. The main legion of the Phantom Fleet flew first in front of the fleet and opened a safe distance from it. This safe distance meets the requirements of the frigate's rapid return to defense, and can also prevent the main body of the rear fleet from being involved in an unexpected battle situation.

There are a total of six Phantom Frigates, and nearly 800 warships form a wedge-shaped combat readiness formation directly in front of the Expeditionary Force. Nearly 100 Phantom Reconnaissance Ships are scattered and scattered on the outermost edge of the fleet, responsible for information reconnaissance tasks, forming the first defensive barrier of the Expeditionary Force.

As time passed, the Expeditionary Fleet finally gradually approached those asteroids.

"It's so fucking weird! How could I meet such a large-scale asteroid here, and there were three consecutive appearances."

The Third Phantom Reconnaissance Fleet is responsible for the front reconnaissance mission of the Expeditionary Force. The soldiers all felt that these asteroids appeared a bit abruptly. According to previous experience in space flight, it is extremely rare to encounter three large-mass asteroids at the same time, just a few light years away from the stars.

"All reconnaissance ships are on high alert and monitor closely!" Yu Liang, captain of the Third Phantom Reconnaissance Fleet, also felt that it was very inappropriate, and he emphasized repeatedly along the way.

The threat of asteroids is not to collide with the fleet. The fleet can fly safely from the asteroid without even adjusting its direction.

Because the Expeditionary Force has been flying in the fourth dimension of four-dimensional space, there is no need to worry about colliding with any celestial bodies in three-dimensional space. During the previous stealth journey, the reason why the fleet needed to change its route and orbit between stars was to avoid being detected by the other party because it was too close to the possible cosmic civilization.

For a civilized world that has mastered four-dimensional space technology, even if there is a three-dimensional space, it can still try to detect the movements in four-dimensional space. Just like a ship sailing in the ocean and is on a two-dimensional plane. Although it cannot contact fighter jets flying in the sky, the existence of fighter jets in the sky can be observed through detectors.

The universe civilization that has not mastered four-dimensional space technology is like a steamer with only a horizontal field of view. They don’t know and cannot look up at the sky, so they naturally cannot find the plane passing by from the sky.

In other words, if this unknown cosmic civilization does not have four-dimensional space technology, the expeditionary force only needs to drive straight in the fourth dimension and pass by them like ghosts without being discovered at all.

This may be the reason why humans who once lived on Earth never observed advanced cosmic civilizations. Perhaps, advanced cosmic civilizations have passed by us many times and leisurely observed our every move, but at that time, we were like ants, but we could not "look up" to see their existence.

Of course, it is almost impossible to directly attack the newly added targets in the four-dimensional space from three-dimensional space, because the target position observed and aimed in the three-dimensional space is actually inaccurate. A shot hits the past, like hitting a phantom.

This is also one of the reasons why the Expeditionary Fleet dares to pass by the universe civilization. If the other party does not ambush the military forces in the four-dimensional space in advance, even if the Expeditionary Fleet is discovered, they can only let them leave without staring at them.

"Captain Yu, I think these three asteroids look brighter." A soldier in charge of monitoring said casually.

"What did you say!?" Yu Liang seemed to have keenly captured something from this sentence.

"Well, I mean these asteroids look brighter than the ones that appear in the average deep space."

The soldier's scalp tightened, but he didn't expect that the captain would have such a big reaction.

"Brighter!?" Yu Liang glanced at the data from the monitoring system and said expressionlessly, "It's indeed brighter."

"That's it, that's it." The soldier was relieved when he heard that the captain who had always been strict thought so, and quickly echoed.

"wrong!!!"

Yu Liang suddenly shouted, but the soldier was almost scared by this fierce shout.

"The light emitted by such a dim red dwarf should be extremely limited, and the reflectivity of these three asteroids is too high." Yu Liang made a judgment immediately, "There is a problem! There must be a problem!"

"Enable high-power detector!" Yu Liang ordered decisively.

"However, we are prohibited from using it on the upper peak"

Before the young soldier could finish his words, he suddenly got a slap on his forehead.

"What are you talking about? Hurry up! I'll take care of the problem!" Yu Liang said without any objection.

"yes!!!"

Five minutes later, the combat command room of the Third Reconnaissance Fleet suddenly fell into a dead silence.

What was presented to everyone was a scene that was enough to make people suffering from intensive phobia feel broken. Yu Liang saw countless dark bright spots floating around the orbits of the three asteroids, almost everywhere, as if surrounding the routes ahead of the expeditionary fleet.

Dark bright spots have a smoother surface and become the target of reflecting the light of stars. It is the light reflected by these dense dark bright spots that increase the brightness of the asteroid by a series when entering the field of observation.

“What are these!?”

"Is it interstellar gravel?"

"No, no, the surface is too smooth!"

The soldiers were speculating.

"It's made of metal!!" Yu Liang widened his eyes, "It's an artificial object! All are artificial objects!"

"How is this possible? This, this number is at least a few billion!" The soldiers fell off their chins in shock.

"Quickly, report to General Sergei immediately!!"

Yu Liang made a quick decision and sent the highest-level alarm signal to the Central Command Center of the Expeditionary Force!

"Woo~Woo~Woo~"

After the message from the reconnaissance ship arrived, the next moment, all the flying units of the Expeditionary Fleet suddenly alerted!!

In the Central Command Center of the Expeditionary Fleet.

"I was discovered after all!" Yuan Shichen said quietly with a cold face.

"Leader, what exactly are those dense things?" Sergey asked seriously.

"The cognitive differences between different cosmic civilizations are too large and cannot be determined for the time being. However, the larger one may be some kind of trigger weapon."

"Space mines, billions of space mines!?" Sergei asked in surprise.

"Maybe it's not a simple space thunder." Harashi-chan added.

"Chief, should you take a detour or continue moving forward?" Sergei asked loudly, "Please give orders!"

"Doing? Other directions may not be smooth. Let the frigate explore the other party's reality first!!" Yuan Shichen ordered.

"yes!!!"

"Guys, get ready for battle!!" Sergei shouted and turned to the combat command center.

"The first, second and third Phantom Frigate takes the lead, and the other combat units support the two wings!!"

"yes!!"

When combat instructions are issued, a group of military staff and commanders are responsible for formulating combat tactics and strategies, while specific combat operations are handed over to computer systems for operation.
