He Bilin silently followed Tao Yuda's footsteps.

Is the gap really that big?

He Bilin recalled his last experience in a holographic theater.

I vaguely remember that before entering the holographic theater, the so-called mimicry is marked on it.

Among a number of simulation scenarios, the simulation of the earth's environment has the highest degree of simulation.

95%.

This is also the reason why He Bilin chose to experience it.

only……

Looking back now, although the scenery I saw was extremely stunning, it always felt indescribable.

Perhaps, this is the breath of freedom that Academician Tao mentioned?

Can a 5% difference reflect such a complex difference?

He Bilin suppressed the doubts in his heart and turned his head to look into the distance.

[Earth] The main port is open, and Xuannv II slowly sails towards the endless deep space outside the port.

Directly facing the port, is a yellowish-colored planet.

That is their destination - Ross 2, the new home of mankind.

...

Rose 2 Star.

Central City.

Lu Yongchang sat in the office and looked at the outdoor projection screen with relief.

In the blue sky, long rainbows pass by.

Each long rainbow represents a Xuannv No. 2.

After 242 years of turmoil, running around, war, and human civilization, we finally got a stable and stable development environment again...

"Drip—drip—drip!!!"

A harsh sirens rang out in his office.

In just a moment, the originally bright office was covered with a bloody bright red!

The next moment, a holographic projection was projected in front of Lu Yongchang!

【warn!】

【Unknown signal was detected!】

[Signal source: Ross 154]

【Signal frequency: 1420 MHz】

【…】

In the bright red holographic projection, the black handwriting looks particularly shocking.

Lu Yongchang's originally soothing mood instantly dissipated.

He suddenly stood up from the chair, his eyes full of horror!

1420 MHz communication frequency!

It has always been a signal band for humans to search for information about alien civilizations!

The reason is very simple.

1420 megahertz is the frequency of a famous spectral line for the emission of neutral hydrogen atoms - the 21 cm spectral line.

As the most common and richest element in the universe, every advanced civilization that has developed to a certain level will be extremely familiar with this nature.

On the other hand, 1420 MHz is an area where radio signals are relatively quiet.

In this signal frequency band, the intensity of various background radiation is almost the smallest.

Therefore, if you want the signal you send is not overwhelmed by the noise emitted by celestial bodies and can be received by advanced civilizations that have developed to a certain level, 1420 MHz is an excellent signal frequency choice.

And now!

In the direction of Ross 154, a signal of this frequency actually came!

I believe there is no need to say more about what this means.

Recalling the unusually brilliant phenomenon more than 60 years ago...

At this moment, Lu Yongchang only felt his whole body trembling and a chill behind him!

"zero!"

Without any hesitation, Lu Yongchang issued an order directly: "Stop all work!"

"Notify Zhao Zijie, the human fleet, the first-level combat readiness state!"

"The whole army will immediately enter the state of radio silence!"

port.

As a harsh alarm sounded on the public communication channel, the open port in the distance slowly closed.

At the same time, the dark blue flames at the tail of several Xuannv II, who were about to take off, quickly extinguished.

Red warning lights began to flash.

"What, what's going on?"

He Bilin, who was born after the Battle of Proxima Centar, was stunned for a moment.

Because of the lack of necessary experience, his brain stagnated for a moment before he came to the answer.

It seems...the fleet is in danger?

"He Bilin!"

As the familiar voice sounded in the team's communication channel, a huge force came from his side.

Even with the electromagnetic boots helping to fix his body, he was still staggered by this force.

He barely stabilized his body and once again sucked the electromagnetic boots on the ground, he turned his head and looked aside.

"Academician Tao?"

When he saw the familiar person, He Bilin's panic suddenly became less. He asked in a hurry: "Academician Tao, what happened?"

"Why……"

Tao Yuda looked extremely serious and there was no smile on his face.

"This is……"

"Level 1 combat readiness alert."

"Usually, it will only ring when encountering other civilizations!"

Listening to the sound coming from the headphones, He Bilin subconsciously held his breath.

As Tao Yuda finished speaking, huge holographic projections unfolded in the air.ъìqυgΕtv.℃ǒΜ

【warn】

【Unknown civilization signal detected】

[All ships, first-level combat readiness status]

Unlike "old fried dough sticks" like Tao Yuda, he has never experienced such a thing since he was born.

"Then...what should I do?"

Thinking of the Battle of Proxima Centar recorded in historical documents, his voice trembled slightly and he asked in a low voice: "What should we do?"

Tao Yuda turned around and walked quickly towards the direction of the command center.

"Conductor Zhao Zijie is still on Earth, so let's go to the command center."

After a moment of pause, Tao Yuda's voice sounded again.

This time, his voice was filled with solemnity and helplessness.

"Be ready."

"The stable life of human beings may be over before it even begins."
