Jiang Yicheng found some "worms" that seemed to be useful, but the problem of water sources was not solved.

Even though these worm-like roots feel quite watery to the touch, the liquid squeezed directly from an alien plant — and possibly an animal — contains too many other dissolved substances to be dissolved.

Jiang Yicheng picked up a trumpet-shaped leaf that she pulled out from the ground, and put it upside down on her head: "Looking at the shape of this leaf, you can directly wear it as a hat to avoid direct sunlight shining on the protective clothing and causing heat." ”

Barrage: I'm sorry I laughed [funny]

Barrage: Oh, my dear Orange, you're such a genius [applause]

Barrage: 2186 (1) Fashion new products are released⊙ω ⊙

Jiang Yicheng glanced at his image on the screen and felt that this was not funny at all. Isn't this like an elongated version of a hat? Or it's similar to the old man of the Earth era who put a lotus leaf upside down on his head.

Many people in the era of interstellar travel have lived in space bases and space stations with only artificial ecosystems for a long time, and some people were even born on Mars, moon bases, and asteroid belt space stations, and have never been to Earth in their lifetime.

But for Jiang Yicheng, they are all young people. Unlike many interstellar explorers born in the era of interstellar navigation, Jiang Yicheng was really born in the age of the earth and was taught to "revere nature" since he was a child.

After the development of brain-computer interfaces to enable consciousness uploading, many people at that time chose to upload consciousness to supercomputers as the body gradually aged. Later, with the realization of artificial womb technology, these people who "died" in the supercomputer were "born" in new bodies and "resurrected" again. This process is known as "intergenerational alternating consciousness transfer", but it is often referred to colloquially as "reincarnation".

The main purpose of "reincarnation" is to save educational resources. For a social system as developed as human civilization, it takes ten to twenty years of education to generate a new population before it can truly become a usable labor force. And if we can "resurrect" the consciousness stored in the supercomputer, we can save the link of basic general education, and only need professional training to let them hold a certificate to work.

Since human civilization still exists in the real universe in the final analysis, governments and enterprises need ordinary people to come out of the virtual world of supercomputers and devote themselves to the construction of the real world. As a result, the "Consciousness Transfer Law" was introduced, which stipulates that a person's consciousness must not stay in the supercomputer virtual world for more than ten years, and those who have not entered a new body after ten years will be forcibly "born".

Jiang Yicheng's "reincarnation" was not forced to be born, she finished reading "Curvature Drive", "Interstellar Navigation Based on General Relativity" and other pre-courses in the spacecraft designer industry when she was in the virtual world, and she got a good number and could be born in a developed area of the earth. Before she went bankrupt and owed debts, she could be said to have had a smooth life, but she couldn't stand the ups and downs of fate......

But these are all off-topic.

As an "old" person born in the age of the earth, Jiang Yicheng knows that he can't complain about the sky. And her background in the age of Earth also made her more cautious in her interstellar expeditions, not superstitious about the function of protective clothing and helmets, but inclined to observe the environment and take advantage of everything available in the environment - which could save her life in the event of an accident.

With an upside-down leaf on her head, Jiang Yicheng changed her direction.

This time she chose to go to the hills to the south. Despite their distances, hills are able to block cold air on the plains, making them prone to precipitation. Moreover, the hills mean local ecological changes, and the species of organisms will be different from other places, where she may find other useful things to build a cover for herself.

"It's hot." Jiang Yicheng said into the drone's camera as he walked, "It's almost noon on the day before Lan Po, and you can see that my shadow is getting shorter and shorter...... The sun was very harsh, and if I couldn't find a source of water, I had to find a shady place to rest for a while. ”

Barrage: I feel sorry for my sister [crying]

Barrage [Yellow]: Forward a tRNA, give an orange a transport~

Barrage: Oh my god, what's the front post?

Barrage: Don't block the subtitles, okay?

Although human civilization has been unified, languages have not yet been fully integrated. However, with the help of weak artificial intelligence (3), the voice during the live broadcast can be converted into text and translated by Jiang Yicheng's spaceship's AI, so as to automatically generate personalized subtitles that can be understood by each viewer. For the audience's comments, the spaceship AI will do the same.

But for someone to spell tRNA with symbols, this can't be translated. And the barrage is too long to block the subtitles, which will definitely be disliked by others.

But maybe it was the "transport" RNA that really transported Jiang Yicheng, and when she walked in front of the hill, she really found a waterhole on the sunny side of a rock.

The waterhole looked like a puddle, but Jiang knew that the rest of the ground had completely dried up in such a hot environment. And the fact that it can maintain a certain water level indicates that it is likely to be connected to the groundwater system – which means that the waterhole should not be stagnant.

"Friends, let's take a look at what is going on inside this pool......" Jiang Yicheng switched the screen signal to the camera built into her helmet, and now the audience saw the same picture as she saw.

She squatted down and poked her head into the waterhole slightly, Jiang Yicheng and the audience of the live broadcast could see clearly that there was a layer of blue-purple "foam" floating on the surface of the waterhole.

"It should be a relatively low-level creature on the blue amber." Jiang Yicheng scooped it with his hand wrapped in gloves, and the foam felt like a sponge cushion, and there were very rough fibers in it to the touch, not like something that could be swallowed. And after all the blue-purple "sponge mats" were fished out, the remaining water looked fairly clear.

"Looks like there's a natural well down there." Jiang Yicheng turned the picture back to the drone lens to avoid 3D vertigo when the audience watched it, "Because the formation environment is similar, the structure of the blue amber is similar to that of the earth." The earth's crust is mainly composed of silica, and there are no heavy metals that are highly toxic to humans in the relatively abundant element (4...... So this water source should be available. However, when it is uncertain whether the native organisms are highly toxic, they still need to be filtered and boiled before drinking. ”

Barrage: Wait, what about suddenly finding out that my sister hasn't lit a fire yet?

Barrage: The front is not in a hurry, one orange is stable, and you can even go without drinking water for two days and not making a fire for three days [funny]

Barrage: Meng Xin, ask, can the atmosphere of other planets be lit on fire [question mark]

Barrage: It's said that it's a habitable planet in the narrow sense, and the living system is a carbon skeleton with an oxidizing atmosphere......

"I see that some friends are concerned about the issue of making a fire, what ...... about this matter" Jiang Yicheng glanced at the scorching "sun" in the sky, "It's too hot now, I plan to build a shed first." ”

As she spoke, she put down the "sponge mat" in her hand and walked to a tall "tree" next to her.

This is not a taxonomic "tree" with rhizomes and leaves and a hard trunk, and it may not even be classified into a taxonomic system similar to that of Earth's plants. Compared with the "woody plant" in the human impression, it is more like a tall fern, with a vascular similar transport support tissue, and basic differentiation, but the overall complexity is still far less than that of the seed plants on the earth.

"This tree grows beautifully (5)." Jiang Yicheng said with a smile, although she knew that the current audience would probably not know about this stalk.

She held the middle of a leaf more than two meters long, and rotated it vigorously to unscrew the leaf from the incompletely differentiated stem: "The trunk of this leaf is quite stiff and can be used as a support." ”

And when Jiang Yicheng was concentrating on building a shed, her audience chatted in the barrage again.

Barrage: An Orange Ancestral Craft - Making Gaier [Funny]

Barrage: Feel that there are fewer people in the barrage?

Barrage: There's an orange doing homework......

Barrage [blue]: It's normal, one orange's live broadcast has been going on for seven consecutive days, and there can't be a lot of people active all the time.

Barrage: Huh? Is it possible that the live broadcast is also turned on when you sleep???

Barrage [Green]: Front, don't be too depraved by your thoughts [squint]

Barrage: Don't say it, there are really people who specialize in watching sleep live broadcasts (not me)

Barrage: Watch Sister Orange work and really eat~

Exegesis:

(1) Here is a tribute to Liu Cixin's "China 2185", and by the way, I will also give Amway.

(2) This is the secondary structure of the tRNA, the black square indicates the empty, and the arrow direction indicates the 5' end to the 3' end. tRNA, also known as transfer RNA, is a major biology student who forwards tRNA at the end of each year to "transport". (I spelled it myself.,I can align it on the mobile APP.,I can't help it if the web version is not aligned)

(3) Weak artificial intelligence: The difference between weak artificial intelligence and strong artificial intelligence is that weak artificial intelligence does not have the ability to reason and solve problems independently, and does not have "self-awareness"; All of the so-called "AI" in this article is weak artificial intelligence.

(4) Crustal element abundance ranking: oxygen> silicon> aluminum> iron> calcium> sodium> potassium> magnesium>......

The order of element abundance of the earth as a whole is: iron> oxygen> silicon> magnesium> nickel> sulfur > titanium>......

Heavy metal ions are mainly toxic because they are easy to form complexes with biological macromolecules. However, heavy elements cannot be formed by fusion for mesomassive stars, and are mainly formed in supernova explosions, so they are less abundant overall.

(5) "Pretty Warning" stalk, from Huanong Brothers.
