Looking out of the porthole at the left side of eternal day, Proxima Centauri's parent star looks like the sun, with the sun blazing in the sky.

Ruan Lin exclaimed: "This is ten times bigger than when we look at the sun on Earth!" Unfortunately, the brightness of this star can only be felt at such a distance. ”

Next to Proxima Centauri are the constellations Centauri α β 0.02 light-years away from Proxima Centauri, and from Ruan Lin's perspective, they are about half the diameter of the Full Moon on Earth when viewed from each other.

The rays of three stars shine on Proxima Centauri B at the same time.

Ruan Lin walked to the hatch: "They are a very stable three-body system, but for this civilization, their mother star is not their source of life, it is the biggest threat to survival!" ”

The ship slowly came to a halt on the surface, and he waited with several robots accompanying him for the moment when the hatch opened.

At the same time, below the surface of Proxima Centauri B, countless Kahn people stopped what they were doing and watched the live broadcast at the same time.

In a low, white building, several Kannes were glued together, staring at the computer screen in front of them.

"Look at their ships! Karn is on top! When will we be able to build it? We're moving to another planet! Damn underground, I've had enough! ”

"What do they look like! Isn't it the same as us! ”

"I'd love to take a picture with this ship! Much more handsome than in the movie! ”

"The elders say they are called Earth Civilization, what does Earth mean? Their planet? ”

At this moment, Ruan Lin's field of vision gradually became broader, no longer the silver-white paint inside the spaceship, and as far as the eye could see, the surface of Proxima Centauri B was like Mars! Everywhere there are intricate small peaks and reddish surface rocks. The external gravitational force is almost 1.3 times that of the Earth.

"Kahn bless you! Dear Earth Civilization! Welcome to the Horn Star. ”

Ruan Lin understood the meaning of this sentence as soon as he heard it, and he had completely mastered their language.

They are about 1.6 meters tall and have two fully evolved front paws, a pure white body, heavy scales on their back and face, lizard-like eyes, orange overall, and their pupils are erect.

This was Ruan Lin's first impression of the civilized creatures, almost no different from what he had imagined. Except for their pure white appearance.

They lowered their heads and put their front paws together towards their chests.

One of them seemed to be holding a camera and a microphone, aimed at Ruan Lin.

Ruan Lin said in a strange pronunciation tone: "Thank you for coming to greet us, we are a well-meaning civilization!" ”

Then he followed their greeting and lowered his head and put his hands together on his chest.

These creatures of the Kann civilization suddenly smiled: "Please follow us, our civilization buildings are all under the ground, and our Great Elder has been waiting for you for a long time!" ”

"Thank you for your hospitality!" Ruan Lin began to set foot on this planet that humans had long wanted to explore with several robots.

As they led Ruan Lin to the Dawn and Dusk Circle Cracks, he was able to get a closer look at them: they were all made of steel, about 300 meters long and 200 meters wide, and these cracks were like "zippers" in the center of the planet, connecting the surface and the underground.

"We've built 30 openings on the planet to connect our underground to the surface! Please wait for us to open the connector! Among them, the Kaen people who walked in the forefront said this, and they couldn't help but look proud.

"Okay! I can't wait to have a friendly exchange with your civilization! Ruan Lin took the initiative to show a friendly side of curiosity.

This is indeed a large-scale project for them who have just entered the information age. From the dialogue, it seems that they do not have a national division, but practice the "elder system" of the church.

There is also such a system on earth, and it is one of the systems of the Christian church on earth.

One of the Kannes walked into the semi-circular white building, and the "zipper" on the surface was slowly unfolding.

These Kaen people stood on both sides and bowed their heads: "Distinguished guests, please first!" ”

I saw that after the opening was opened, I looked down at an elevator car. Its length and width are almost the same as the length and width of this zipper.

Ruan Lin muttered in his heart: This elevator goes to register for the Guinness World Records, and the ironclad ranking can break the record.

This elevator car does not have any seals, and there is an escalator in the center for going up and down. Ruan Lin walked down with the robot behind him, and they followed.

The surrounding Kane people looked at the survey robots with extremely strange eyes, wanting to say something, but they didn't speak.

After 10 minutes of descending the elevator, the elevator car is no longer surrounded by rock formations and dust beneath the surface.

Ruan Lin saw an extremely shocking scene: looking down from the current distance, Proxima Centauri B's underground had almost been dug through nearly 10 kilometers! As far as the eye can see, the upper floors are empty. Their urban architecture as a whole is relatively uniform, like silver-white rectangles rising from the ground, each with blue glass windows, and the maximum building height is about 800 meters, and these underground buildings stretch out into view.

Ruan Lin noticed an anomaly: now his body temperature was only 29 degrees, and the surface of the city they were on was at least 15 kilometers away from the surface of Proxima Centauri B.

For every 100 meters of depth on Earth, the temperature rises by about 3 degrees Celsius.

The closer you are to the core, the hotter it gets, which should be something that every planet has in common.

With this question in mind, Ruan Lin arrived at their surface, only to see countless Kaen people standing on both sides of the elevator to surround Ruan Lin and his party, and the place became as noisy as a large music festival. They scrambled to take pictures of Ruan Lin's appearance.

Ruan Lin smiled on the surface, but complained inwardly: Now I can understand how the pandas in the zoo feel.

One of the Kannes closest to Ruan Lin, who was about 1.1 meters tall and looked to be very young, asked a question in a loud voice: "Respected Earth civilization, can you teach us how to build a spaceship?" ”

After he asked this question, the Kannes, who could not see the end, stopped shouting.

It seems that they really want to have ships.

Ruan Lin was stunned for a moment, maybe this was the question he wanted to raise, or maybe this was already planned by the upper echelons of their civilization.

Either way, he decided to take the initiative to show his kind side: "Of course! I'll be on your planet for a while, and I'll teach you the art of building ships!" ”

The Kane people were instantly agitated, and some of them had begun to cry uncontrollably.

The first few Khanes began to salute, and it was like a tidal wave, and countless Khanes bowed their heads and crossed their hands.

It seems that they also have a wonderful story...
