Early that morning, the New Mars Central Base received a radio signal from Luo Fan. The signal was obviously sent from a large radio telescope and was very clear.

The signal is carried by low-frequency radio, with a cycle of one minute and thirty seconds, with a fifteen-second interval in between, repeated three times.

Its content was clearly self-analyzed and compiled, with each signal beginning with universal scalar quantities such as the speed of light in a vacuum, absolute zero, etc. As long as the receiver had a correct understanding of the universe, they could interpret the entire signal through these headers.

This is a method commonly used by primitive civilizations when a third type of contact occurs. The United Nations of Earth also used this method in ancient times.

But now, they prefer to directly send two armed research vessels to the newly discovered galaxy, and then kindly notify the indigenous civilization there.

Open doors, free trade.

"Hello, friends from outer space. We are the Luofan people, the native life forms born in this galaxy. We noticed that you are building some equipment on the third planet. Can you tell us why?"

Translating the signal was naturally not a problem for Bai Yi. In fact, he had already mastered the language of the Luofan people through their Internet. So he picked up the virtual pen and began to reply.

Luo Fanxing

MASA Headquarters

As the first to discover extraterrestrial visitors and also the one with the most extensive space experience, MASA naturally became the chief executive unit of this exchange operation.

At the behest of the United Nations, MASA used the country's largest radio telescope to send communication signals to the third planet.

For them, all they can do now is wait.

At that moment, half of the massive screen in the MASA control room displayed the various conditions of New Mars. The increasing intensity of sunlight reflected represented the gradual replacement of New Mars's rusty red surface with a silvery-white metal. According to MASA's estimates, within three months at most, that metal would cover the entire surface of New Mars.

The other half of the screen showed more than twenty Lofan people of different genders, races, ages and skin colors. They were the Secretary-General of the United Nations and leaders of various countries on the planet.

Due to the cautious attitude towards outsiders, the backgrounds of most of them show that they are in a safe bunker.

"It's been almost an hour since the signal was sent. Taking into account the time for radio transmission and translation, it's almost time for a reply."

MASA Director Pop silently calculated the time, his hand holding his coffee trembling slightly. Nearing 60, he had begun to gain weight, and his long-standing gray hair was beginning to fall out. His cloudy eyes were fixed on the wall-sized main screen.

Receiving stations in various regions have pointed their antennas at the new Mars, but so far, all they have received is silence, with only the rustling of the ever-lasting background radiation of the universe.

Suddenly, the originally silent and monotonous noise curve began to fluctuate violently like a frightened snake, and the signal curve began to boil like a pot of water.

"Signal received, the source is...the target planet!"

Someone shouted, with excitement in their tone.

"Immediately! Translate immediately!"

Pope ordered excitedly, not even noticing the coffee spilling from his hand.

"Um... no need for translation."

The translation team looked a little embarrassed. "The reply was written in plain text, and in the most common format."

"What?" Pope was a little surprised.

"Let him out."

The content of the reply was immediately displayed on the home screen.

"Dear Luofan people, I am the third generation self-evolving AI border guard of the Galactic Alliance, number 9527. You can also call me Bai Yi."

"I have come to your system to deal with a great threat that will face the entire galaxy in the foreseeable future."

"The Galactic Alliance arrived in this system approximately a thousand years ago and contacted your ancestors approximately 600 years ago, when you were still in the late feudal era. If you have any questions, here are some excerpts I found in your database. I believe you can find your own answers from them."

"Also, I suggest we establish a two-way real-time communication channel, rather than having to wait an hour for a reply like we do now. I'll prepare the relevant communication equipment. If you agree, please let me know during our next communication."

At the end of the article, Bai Yi attached a link, which contained some information that Bai Yi had excerpted from the Luofan database about the contact between ancient aliens and his ancestors.

The relevant content is quite detailed, but thousands of years have passed, and except for the descendants of some of those who originally came into contact with it, other Luofan people just regard it as a strange story in the market.

Back on New Mars, Bai Yi had begun preparing communications equipment after receiving his reply. He didn't believe the people of Luofan would refuse the opportunity to experience superluminal communication. Of course, he couldn't actually give them a tachyon communicator. All he had to do was place three modified communications satellites in Luofan's synchronous orbit. These tachyon satellites would receive electromagnetic signals in a designated frequency band and convert them into tachyon beams for transmission to New Mars. They would also translate information sent from Mars into electromagnetic waves and transmit them back to Earth.

"That's it," Bai Yi said, controlling the robotic arm to load the three satellites into the shuttle's cargo hold. Now, all he had to do was wait for a nod from the other side. In three minutes at most, the shuttle, equipped with its jump engine, would have the first satellite installed.

As he said this, he wrote another letter and placed it in the shuttle's main engine. As long as all three satellites were deployed, the letter would be sent to MASA.

This is what he wrote in the letter.

"Dear Luofan people, hello. I have deployed communication satellites in your synchronous orbit. Their positions at the zenith are as follows. From now on, please use the following electromagnetic frequency bands for directional transmission and reception. Please see the attached letter for the relevant communication protocols. Theoretically, if you perform the above operations correctly, the communication delay between us will not exceed 5 seconds."

"This delay is sufficient for Landlord."

Bai Yi put away his pen and smiled as he looked at the letter in front of him.

Just now, he received a message from MASA, confirming their agreement to construct a tachyon satellite in Luofan's synchronous orbit. After all, for a civilization of their level, establishing communication with another civilization, especially a much more powerful and potentially benevolent interstellar civilization, is a once-in-a-lifetime opportunity.

Even if you cannot cling to the other party or gain direct benefits from them, it is also very good to simply ask about the crisis that threatens the entire galaxy and figure out the current position of your own civilization in the galaxy.
