At present, Su Meng's spacecraft is heading towards the planet at a speed of 100 kilometers per second, Su Meng uses laser ranging to measure the distance from the planet, and then calculates the diameter of the planet, which is twice as large as the earth, more than 20,000 kilometers.

Su Meng is 50 million kilometers away from there, and it takes almost six days to get there.

Su Meng came to the front of the console and began to operate.

Today's task is to analyze the atmospheric composition of the opposite planet, at a distance of 50 million kilometers, using spectroscopic analysis instruments to analyze the atmospheric composition of the planet, which is already extremely accurate.

Previously, the analysis of vital activities was carried out in the infrared band, but now it is in the visible and ultraviolet bands.

After about nine hours, the results of the analysis were all out.

On the opposite planet, the atmosphere is dominated by inert nitrogen, with 22% oxygen and trace amounts of carbon dioxide.

The impact of this planet on Su Meng was great, and this was the first time she had seen the second planet of life besides the earth.

Su Meng plans to leave her sister on the spaceship after waiting there, and then go to the surface of the planet to explore by herself, catch a few natives, and build a lighthouse on this planet if the conditions are right, and it will be much more convenient when she comes here in the future.

This galaxy is at the edge of the Milky Way, and the interstellar space here is very empty, so the matter is very precious, and the most important thing Su Meng has to do when he goes here is to store enough material.

However, Su Meng was not ready to take the material on the planet, her ideal target was a planet about 130 million kilometers outside the orbit of the planet, which was very desolate and similar to Mars.

Su Meng was going to go to this planet to stay for a while, and then go to the target planet to collect materials when he left.

After staying in space for decades, Su Meng is also uncomfortable, if she doesn't go to the planet to relax her nerves, I'm afraid she will get sick, after all, her life is eternal, and immortality brings more longing and deeper emotions.

The star of this galaxy is an ordinary yellow star 1.8 times larger than the Sun, 2 billion years younger than the Sun, and is in a more active phase.

There are six planets in the galaxy, three of which are rocky and three are gaseous.

About five days later, Su Meng's spaceship was only tens of thousands of kilometers away from this living planet.

Looking at this living planet at this distance, it already occupies half of Su Meng's horizon, it is really too big, Su Meng can even see some artificial creations on the surface of this planet through optical telescopes, but he can only see the general outline, which seems to be some huge outlines similar to ancient cities.

Su Meng looked at her sister in her arms, I don't know if there is danger on this planet, so Su Meng wants to leave her sister on the spaceship.

There is air suitable for survival in the rest area, and my sister doesn't need to be able to hold her breath to stay there very comfortably, Su Meng hugged her sister to the rest area, and then stopped time to slow down, waiting for her to wake up.

Su Tian woke up two hours later, and Su Meng told her that they had come to a living planet, but the specific situation had not yet been discovered.

"Sister, I'll go down and investigate it myself, and you can control the miniature detection here to take a look." Su Meng commanded.

Su Tian nodded obediently, and she was unconditionally willing to obey her sister's request.

The miniature detector made by Su Meng uses the technology of the earth, has two drive engines, and the energy source is a miniature nuclear battery, one nuclear battery can supply the probe for continuous activity for a month.

Su Meng kissed Su Tian's forehead, touched her hair, and then left the rest area with the miniature detector body with four spiral wings.

Soon Su Meng came to the outside of the spaceship, and at this moment Su Meng's spaceship entered the synchronous orbit of the planet, which is much more stable than other orbits, which can prevent accidents.

Su Meng flew towards the planet with a miniature probe, and her speed of flight reached more than 300 kilometers per second, and about ten minutes later, Su Meng entered the atmosphere of the planet.

As soon as he entered the atmosphere, he immediately felt great resistance, which made Su Meng have to slow down his flight.

Su Meng flew towards the surface of the planet at a speed of one kilometer per second.

Su Meng's chosen target was a piece of land in the middle of the ocean, with seven huge cities and countless small buildings.

The rotation period of this living planet is 36.4 hours, and a day here is at least half longer than a day on Earth, and a year here is more than 800 days.

This living planet has two moons, and both of them are barren vacuum worlds, so Su Meng didn't have the idea of landing on those two moons first.

The planet's orbital inclination is only 3 degrees, and the change of seasons is not so noticeable here.

When Su Meng got closer and closer to the ground, she felt that the temperature here was about 19 degrees.

A minute later, Su Meng finally stepped on the ground.

The gravity of this planet is a little smaller than Su Meng thought, only 1.2 times that of the earth.

There was a kind of grass half a meter high growing on the ground, the sky was as blue as washing, and the white clouds were fluttering, Su Meng had the illusion of returning to the earth at this moment.

However, the white moon hanging on the edge of the sky, which was the size of a millstone, made Su Meng exhale softly, knowing that there was no more earth and that human beings had been extinct for a long time.

At this time, Su Meng heard the sound of snorting not far away, so Su Meng's heart moved, her body became completely transparent, and then she flew up.

Su Meng had already released the probe before landing, and now the probe was suspended more than ten meters next to Su Meng, and when Su Meng disappeared, the probe stopped moving.

"My sister is invisible, and I can't see it anymore." Su Tian, who was tens of thousands of miles away, was remotely controlling the detector, and when she saw her sister disappearing, she hesitated for a while, and then controlled the miniature detector to choose a random direction and leave here.

After Su Meng was invisible, he flew in the direction where the voice came from, and soon Su Meng came to the front of a camp composed of tents.

Su Meng saw that in the middle of the camp, many creatures with a height of about one meter ** were standing there, they were gathered together in twos and threes, and some were lined up, as if they were practicing.

So Su Meng knew that this must be an indigenous military camp.

These creatures have four arms and two legs, and a tail about 1.7 meters long that drags on the ground, their facial features look like water chestnuts, and their skin is all white, a bit like the skin color of Westerners on Earth.

They also have hair, but they don't grow long, and it seems that because of the barracks, their hair is the same. It's all the kind of hairstyle that sticks up in the sky, and it looks extremely weird.

Su Meng listened to the fluctuations in the air with super senses, some faint syllables, but they were very changeable, it seemed to be the language of these creatures.

Su Meng began to use his analytical powers to learn these languages, and after about ten minutes, Su Meng mastered the pattern of about 600 syllables.

Of course, if you want to really learn their language, Su Meng still needs to find someone to learn.

However, the military camp was obviously not a good place to study, and Su Meng flew over this military camp of about 30,000 people and flew towards the city located north of the military camp.

Soon after, Su Meng came to the outside of the city, she flew directly into the city, landed in an unnoticed corner, and changed her body to make herself look like the woman here.

With a tail and four arms, it feels really weird.

Su Meng created a dress that was copied through super senses and wore it on his body.

The clothes worn by the women on this planet resemble those of the ancient Han Dynasty, but because the people here have four arms, there are some changes in style.

Su Meng changed her face slightly, making herself more like a woman in this world.

Then Su Meng walked out of the alley and came to the street.

The street is very lively, many people are talking, shopping, and there are people selling things, of course, these people sell things, Su Meng can only understand 80%, many things, Su Meng doesn't understand what they are for.

Su Meng walked to the front of a stall and picked up a tube-shaped flute-like instrument, which seemed to be carved from some kind of high-end stone.

The stall owner said a word to Su Meng, Su Meng couldn't understand the meaning, took a look at it, analyzed the structure and principle of the instrument with a super sense, simulated it in his mind, and then put the instrument down and continued to walk forward.

There are a lot of people talking on the street, and Su Meng is constantly analyzing the other party's language, especially when someone is buying and selling things, which is of great help to Su Meng to learn the language here.

After walking the street for about half an hour, Su Meng came to a stall selling food and spoke a few syllables in the language for the first time.

The stall owner nodded indifferently, and one of the four arms made a gesture to please see, responding with a few syllables.

The corners of Su Meng's mouth showed a meaningful smile, and she completely understood what the other party meant.

Su Meng pursed her lips, she has mastered 70% of the language here now, and she can communicate simply.

Su Meng said in the language here: "I like this fruit very much, how much does it cost?" ”

The stall owner responded, "Beautiful lady, only 2 iron coins each." ”
