Donglin Galaxy.

This is the edge region of Orion's cantilever 557 light-years away from the solar system.

A dark matter spacecraft was detached from the warp and anchored on the fourth planet of the Donglin system, a desolate terrestrial planet similar to Mars.

It was named "Red Sand Star".

Zhang Beihai was in this exploration spacecraft.

"Counselor Kobayashi, are you sure it's this planet?" Captain Cook asked with some doubts.

Kobayashi Yuan nodded: "Captain, the reality of the information of the Exploration Department is this planet."

"Strange, this doesn't look like a living planet?" Cook scratched his head.

Kobayashi was not surprised: "Captain, don't use the earth as a reference. There are thousands of lives in the universe, some of which are similar to humans, and some that are completely different from humans."

Cook smiled awkwardly: "I'm too rigid."

"Then follow the established procedures and send explorers into the planet!" Kobayashi changed the subject.

"OK, Captain Zhang! You lead the team to land!"

"Yes! Captain!" Zhang Beihai saluted and replied.

Then he took 8 quantum warriors and entered the interior of the planet from the dark world.

The planet was discovered because the secret spy satellite that the Human Revolutionary Alliance had placed here before accidentally received a set of electromagnetic wave signals.

The source of the signal is the red sand star.

After Zhang Beihai and his party entered the interior of the planet, they came out of the dark world and began to search for traces of life.

At the beginning, Zhang Beihai and others' target was locked underground.

Quantum warriors can ignore the barriers of apparent matter, easily penetrate thick rock formations, and enter deep underground.

However, as time passed, Zhang Beihai frowned, because they did not find any artificial traces underground, nor did they detect any special heat sources.

three days later.

9 people meet again.

[Team Zhang, no signs of life have been found in the eastern canyon area. ]

[The same is true in the southern plateau, not to mention artificial traces, even microorganisms do not thrive. ]

Zhang Beihai frowned: [Strange, there are electromagnetic wave signals emitted regularly, why is there no trace of artificial activity? ]

Suddenly, his eyes narrowed, shouldn't it be...

He immediately reported his guess to the spacecraft through quantum communication.

Captain Cook also became solemn after listening to Zhang Beihai's report.

inside the cockpit.

"Counselor Kobayashi, what do you think?"

"Very easy, wait!"

Captain Cook was stunned for a moment, and then reacted: "You are planning to wait for that signal to appear again."

Kobayashi nodded: "Yes, our spaceship is not made of obvious matter, as long as we maintain the invisible state, under normal circumstances, as long as the civilization with low dark side technology, it is difficult to find us, let us look at each other. What do you want to do?"

"OK." Captain Cook also knew that this was the safest solution.

Soon Zhang Beihai and his party withdrew the spaceship.

18 Earth Days later.

An alarm sounded inside the spacecraft.

[Unknown electromagnetic wave communication detected, location 367, 251, 037...]

On the holographic map of Chisha Star.

The location where the electromagnetic signal was emitted was on a mountain in the southern plateau with nothing but bare rock and sand.

After the electromagnetic wave communication was launched, under the blessing of the ionosphere of this planet, the power increased by a dozen times, like a high-power broadcasting station.

"This is..." Cook looked suspicious.

Zhang Beihai reacted instantly: "I see, this is fishing."

"Fishing? Hmm! That's right, the other party is indeed fishing." Kobayashi understood: "Since the other party is fishing, it means that they are on this planet, or a nearby planet, with monitoring satellites and the like."

After thinking about it for a while, everyone reported the situation to the headquarters.

When Wang Gao heard the news, he just gave them an instruction to keep them still and not expose them in front of each other.

At the same time, he instructed other exploration teams not to expose them easily, especially planets that have no signs of life and continue to emit electromagnetic wave signals. Don't take it lightly.

The water in the three-body universe is too deep, and if one is not good, it may capsize in the gutter.

At this time, Cook, Zhang Beihai and others in Chisha Star are secretly searching the entire planetary system, and they want to find the hook of this fishing civilization.

Near the signal transmission point on the Chisha star.

Zhang Beihai and others are in the quantum state of dark matter, and they are carefully detecting here, but they have not found any transmitting equipment here.

[Strange, logically speaking, even if we use stealth technology, it has no effect on us. How can we not find it? ] A member of the team said suspiciously.

Zhang Beihai was also thinking.

[Could it be the side of the dark world? ] Another player guessed.

[Impossible, we just came out of the dark world, if there is something in the dark world, we would have discovered it long ago. ]

A group of team members discussed this strange phenomenon.

Suddenly Zhang Beihai had an idea: [Could it be a sophon technology similar to the Trisolaran? ]

[Tomoko? That's possible. ]

After having this guess, they stayed in place for more than three months, during which time the signal point emitted 4 electromagnetic waves.

Through these several monitorings, they really found some abnormal situations. The other party did use a technology similar to Sophon. There are more than a dozen neutrons here, which were transformed into special robots.

Cook and Xiaolin on the spaceship also became more and more cautious.

If they are ordinary civilizations, once they receive the signal, whether they choose to explore or directly attack here, they will expose part of their intelligence to the eyes of the other party.

After marking this planetary system as a "yellow warning area", Captain Cook drove the spacecraft to the K28703 planetary system, which is 581 light-years away from the solar system.

This planetary system is dead, but with the experience of the previous planetary system, their actions are very careful to hide.

Explore complete here.

Now if you continue to the east, you have to cross the blank interstellar area before you can enter the cantilever area of ​​​​the Centaur.

Captain Cook did not hesitate.

After all, inside their dark matter spacecraft, there is a special quantum teleportation cabin that can go back to Earth or other bases at any time.

What's more, in order to ensure safety, the Human Revolutionary Alliance does not intend to develop unmanned terrestrial planets on a large scale.

As the saying goes, if you often walk by the river, how can you not get wet shoes.

Wang Gao never thought that in the underground ~lightnovelpub.net~ of terrestrial planets, the exploration of other civilizations could be avoided.

For example, the encounter of Captain Cook, Zhang Beihai and others in Chisha Star this time made Wang Gao more vigilant. If there are hidden back-hands from other civilizations in the developed planet, then the problem will be troublesome.

Therefore, Wang Gao is more inclined to starship mode, rather than planetary mode.

The spaceship can be moved at any time, but there is no way for the planet to move quickly.

Now the Human Revolutionary Alliance occupies a total of 13 terrestrial planets, and Wang Gao has planned to build a batch of generation-level spacecraft to house humans on Earth.

In the three-body universe, guerrilla warfare is the king of survival.

If you want to occupy a fixed planetary system, unless you have the strength of singer civilization and marginal civilization, don't be delusional.

The Milky Way is currently one of the Singer's areas of control.

Of course, there is also a light particle civilization here.

These two civilizations are cosmic scavengers in the nearby star fields, and the Human Revolutionary Federation does not want to provoke them at this stage.
