Jiang Yicheng's shuttle was inserted diagonally into the atmosphere of "Blue Amber", and the tremor of the body was more pronounced after entering the troposphere. At an altitude close to the ground, the shuttle changed its attitude, and the side engines rotated 90 degrees, and the body slowly fell while jetting downward, until the lowered bracket "stepped on" the land that did not belong to humans for the time being, splashing a circle of rose-colored dust.

Barrage: I hear the sound of landing!

Barrage: A big hole was smashed by an orange on the ground [funny]

Barrage: Landing success (1/1)

Jiang Yicheng opened the hatch, and the difference in air pressure between the inside and outside caused the hatch to make a slight scratching sound. She then throws the drone out of the capsule, leaving it suspended in the air with the camera facing her.

"Well, friends, we've reached the surface of the blue amber now." Jiang Yicheng rolled out of the hatch and jumped to the ground but fell because of the habitual overexertion of his muscles when he landed, "Oops...... Blue Amber's gravity is still a little uncomfortable. ”

Barrage: Ahhhhh I feel sorry for an orange mother who loves you!

Barrage: Teleport over and hold my family with an orange~

Barrage: Can you not be so in the front circle? What is Survival Challenge Wrestling?

Even jumping from the cockpit of the shuttle more than three meters above the ground and wrestling is really nothing to Jiang Yicheng. Almost immediately, she got up and looked back at the shuttle. The shuttle's engine re-ignited, lifted off vertically, changed its attitude, and soon disappeared into the blue-purple sky (1).

"Okay, my shuttle is gone...... Now I'm alone in the central part of the Equatorial continent of Lamber, where the temperature is currently 315 Kelvin, or 42 degrees Celsius. Jiang Yicheng looked around, and the drone's lens also recorded the surrounding environment, "You may not be able to see it from the screen, but the sunlight here is really strong...... The suit is not actively temperature controlled, and I'm feeling hot right now – the landing site is a bit less friendly. ”

The land of "Blue Amber" is dark blue with a hint of purple when viewed from space, but the place where Jiang Yicheng landed is similar to the savanna on Earth (2). At this time, it is a season similar to the dry season, and the ground is covered with a layer of light blue "thatch" with long leaves, which resembles a grass, and the ground is flat, so that you can see the taller "trees" dotted around and far in the pasture.

"To be honest, I'm a bit of a ...... now," Jiang Yicheng muttered, and then said to the camera, "There is no developmental research on Lanper, so our understanding of the native life system here is very limited. To be on the safe side, I'll have to find a 'Gai'er for myself. ”

Barrage [Green]: For newcomers, the lid that an orange says refers to shelter, which is one of the four elements of survival in the wild.

Barrage: The Four Elements of Survival - Talking and Singing [Dog]

Barrage: Thank you for the green word science!

Barrage: The Four Elements of Survival - Eating□ Drinking, Gambling [Funny]

Barrage: Why are there memes everywhere?

"I see that I have friends who have the four elements of popular science, and I want to mention it." Jiang Yicheng casually explained while observing the surroundings, "The shelter in the four elements of survival in the wild is also the meaning of shelter, and I am used to calling it 'Gai'er'. The other three are water, fire, and food, with fire being necessary to expel native animals, which is necessary for safety. ”

"But if you're not a professional, in a biosphere that doesn't originate from the earth and you don't know much about it, try not to drink natural water, especially not to eat native organisms. This channel of mine is to show an ideal situation with the help of a combination of antibiotics, and you should never imitate it without professional guidance. ”

Barrage: Got it~

Barrage [purple]: Understood~

Barrage: Got it~

Barrage: How to send a color barrage? Blue purple looks good [star]

Barrage [Green]: The color barrage is exclusive to old fans_(:з"∠)_

Jiang Yicheng has taken the route of cooperating with the platform from the beginning, and has not opened a channel for fans to reward, so the audience experience in her channel can basically only rely on the viewing time, sign-in and message, etc., and the proportion of color barrage is relatively small. Those who meet the standards of old fans are basically those who have watched it for at least half a year, and they are at least real "experts" who have watched five or six episodes of survival challenges in a row.

However, when you first land, it is dangerous to pay too much attention to the message.

As a habitable planet that produces life independently, the axis of rotation of "Blue Amber" is also basically parallel to the axis of rotation (3), which leads to the regular rotation of the liquid inner layer, thus forming a magnetic field similar to that of the Earth, which plays a centralized role in shielding cosmic rays. Therefore, the division between the north and south poles of "Blue Amber" is natural, and Jiang Yicheng's drone's built-in magnetic pole positioning system can also help her judge the basic direction.

Jiang Yicheng squatted down and grabbed a handful of soil from the roots of the light blue "thatch" with his hand, which was wrapped in a hazmat suit and gloves. The topsoil has a very low moisture content and a light rosy color, presumably due to the small amount of iron ions in it and the pigment left behind by the decay of native organisms. The soil beneath the topsoil is a little wetter and darker, but not far enough to extract water from it using simple physical methods.

Barrage: The color of the soil looks good [than the heart]

Barrage [Green]: Shocked! The famous interstellar explorer One Orange wants to eat soil on an alien planet!

Barrage [Blue]: Don't mess around, this is to analyze the soil moisture content......

The area is indeed very much like a savanna, and the "thatch" around it is very dry, and it is almost impossible to get water from these organisms that seem to be classified as plants.

Jiang Yicheng looked into the distance, and although at first glance she was surrounded by almost identical "savannas", she still noticed that the scenery was somewhat different in the south-east, where the surface vegetation was lighter in color, and there seemed to be some plants between the "thatch" on the bottom and the "trees" on the upper layer.

"I'm going to go that way first. Since I landed along the morning and dusk line, it was the morning of the 'day' for Lamber, and there were still four or five hours of light to find or build a suitable 'lid'. Jiang Yicheng pointed to the south-east direction in the distance as he spoke, and the camera of the drone also turned over.

"The gravity of the blue amber is about nine-tenths of that of the earth, and this gap is actually relatively easy to get used to. For example, the elevator in an ordinary house can reach an acceleration of one meter per square second in the deceleration section, so the gravity in the elevator is equivalent to almost 0.9G, which is similar to the gravitational feeling on the surface of the blue amber. ”

Barrage: An orange said that it felt similar on the surface, but in fact, he fell as soon as he arrived at the place hahahahahaha

Barrage: Falling Orange [Squint]

Barrage [Blue]: Orange Fall [Funny]

Barrage: Is Sister Yicheng's real name called Yicheng?

Barrage: No, my real name seems to be called 袆成......

Barrage [yellow]: Mr. white characters in front, 祎 read yi, 袆 read hui ah [sweat] (4)

Barrage: I'm blind, what's the difference between these two words [Khan]

Barrage: Earlier, what do you know about corneal laser vision correction surgery?

Jiang Yicheng walked towards the light-colored grassland in the south-east direction. There is a vacuum layer on the bottom of the boots of the protective suit, but you can't feel the heat on the ground, but the shoulders and back of the composite fiber fabric are exposed to direct sunlight, and they are already faintly heated. It was not long after the "sun" came out in the morning, and Jiang Yicheng couldn't help but worry a little about what to do when it was really noon.

In fact, although the star orbiting "Blue Amber" is much hotter than the surface temperature of the sun of human civilization, its mass is smaller, and the total radiation power is slightly lower than that of the sun. However, one of the criteria for a habitable planet is that it is located in the "Goldilockiel Belt (5)" of the star, and if "Blue Amber" can be recognized as a habitable planet, it means that its average surface temperature is "just right". And the equatorial region where Jiang Yicheng is now is the hottest place, and it will obviously be much higher than the temperature that can make people feel comfortable.

But heat isn't the most serious problem for interstellar explorers in protective suits.

Although they can also feel hot, humans are one of the few animals on earth with an excellent heat dissipation system, and protective clothing can help people evaporate heat through sweating to avoid thermal radiation sickness. However, sweating a lot in order to dissipate heat will accelerate the loss of water in the human body, so Jiang Yicheng must find a "cover" that can avoid direct sunlight as soon as possible, or find a water source that can be used to cool down.

Exegesis:

(1) Blue-violet sky: According to Rayleigh's scattering law, when the linearity of the scattered particles is less than the wavelength, the scattering intensity is proportional to the fourth power of the frequency, so the sky will show the color of visible light at the short-wave end. The Earth's sky is blue due to the weak violet light emitted by the sun and the strong absorption of violet light by the outer layer, and the stellar emission spectrum set in this paper is more blue-violet, so the sky is blue-purple in the human eye.

(2) Savanna: a vegetation environment formed by tropical seasonal arid climate, usually covered by herbaceous plants in the lower layer and sparse canopy in the upper layer; The savanna is considered to be the environment where the ancestors of humans lived.

(3) Regarding the direction of rotation and the direction of revolution: if the celestial body has not been violently impacted, its rotation direction is determined by the direction of rotation during the accretion disk period when the celestial body was formed.

(4) Yi, which means "beautiful", is mostly used in personal names; 袆, which means "the sacrificial garment of the ancient queen; the knee covering of the ancient court clothes".

(5) Goldilocks zone: the "Goldilocks-zone", also commonly known as the "habitable zone", refers to the ring area in the star system that allows the presence of liquid water on the surface of the planet and the temperature is moderate, and a galaxy may not have a "Goldilocks zone".

"Goldilocks" is derived from the fairy tale "Goldilocks and the Three Little Bears", in which Goldilocks prefer "just right", and is often translated as "Goldilocks" (possibly a mistranslation from Stephen Hawking's popular science book The Grand Design).
