In Jiang Zi's eyes, Titan is a planet without mountains, it is wider than any plain on the earth, the liquid forms a standard horizontal plane under the action of gravity, he stands in the middle of the knee-deep lake, feels that he is an old farmer standing in the paddy field planting rice, minus 180 degrees Celsius liquid alkane is the water in the rice field, but unfortunately there is no seedling in his hand - the ancestral rural plot of the Chinese inexplicably comes to mind, really all the time thinking about farming.

The thermal insulation effect of Tiefutu is undoubtedly extremely amazing, and there is probably no second set of protective clothing in the world that can withstand the low temperature on Titan, which strongly supports the huge temperature difference of 200 degrees Celsius.

"Buy a match, buy a match." Jiang Zi was spinning in place, he was really bored, Dabai didn't come back, Tiefutu showed that five minutes had passed, but he subjectively felt that fifty minutes had passed, "Does anyone want matches?" Does anyone want matches? Lalala, lalala, I'm a little match seller for girls......"

The sky began to snow one after another, I don't know what kind of snow it was, Jiang Zi stretched out his hand, the snowflakes fell in his palm for a long time, different weather on Titan will snow differently, because of the low gravity and low temperature, sometimes rare frozen clouds will be formed, frozen clouds are formed by the sudden solidification of droplets in highly saturated clouds, crystal branches grow rapidly in extremely low temperatures, snowflakes are joined with each other before they can fall, they grow rapidly from top to bottom, and finally grow to the ground, and finally form a huge ice crystal foam, The foam is filled with air and is extremely light – the main component of Titan's atmosphere is nitrogen, which has a boiling point of minus 195 degrees, so it is always in a gaseous state.

The director once said that they are like fragile low-temperature aerogel, frozen clouds can continue to grow on their own basis, Jiangzi has seen dozens of kilometers long frozen clouds, they are like a city wall across the ground, the color is a faint yellow, a poke is a hole, but the growth of frozen clouds is not endless, when the ice crystals at the bottom can not withstand the mass of the upper layer, the frozen clouds will collapse, this phenomenon has a special term, called "cloud collapse".

Frozen clouds are hard to grow enough to collapse because they are too fragile, and Titan is a planet with a harsh climate, and when the wind blows, there are no clouds.

"Is there anyone coming to buy matches?"

Jiang Zi let out a long howl, but no one responded.

Selling matches on Titan is undoubtedly a world-destroying feat, and if Andersen wrote this fairy tale set in Titan, then when the little girl slips the first match, the whole city will have to follow her to meet her grandmother. But the only person on Titan wandering around is probably Keir Horton, who would be scared to death if he appeared in the fog and staggered to Jiangzi for matches.

However, instead of being alone on this vast planet, Jiang Zi would rather have someone to keep him company, whether he has been dead for years or not.

"Does anyone want to buy matches—"

Jiang Zi turned around and continued to howl.

"Yes." Someone replied coldly.

"Holy!" Jiang Zi was frightened, "Dabai, can you not suddenly appear?" Do you know how scary this is? ”

"Mr. Stationmaster, the positioning has been completed." Dabai said, "I have already planned the route back to Cassini Station, please wait a moment, Dr. Liang Jing is on his way." ”

Soon Jiang Zi saw Liang Jing, the crimson figure appeared in the thick fog, looking around with his headlamp, Liang Jing obviously did not have such rich experience in outdoor activities as Jiang Zi, he staggered and fell into the lake, fluttering and getting up, quite embarrassed.

Jiang Zi stepped forward to help him up, Liang Jing shook the lake water on his body, and patted his pants, "This road is too difficult to walk." ”

"Because there are fewer people leaving." Jiang Zi said, "There was no road in this world, but when there were more people walking, it became a road." ”

"Big White!" Liang Jing shouted, "What should we do next?" You just said you've pinpointed us, give us a roadmap! ”

As soon as he finished speaking, the two of them saw the road map on their helmets.

"The two of them are two thousand four hundred and seventy-six meters away from Cassini Station in a straight line." Dabai said, "I have projected the specific path into the helmet of the two of you, please check." ”

Liang Jing and Jiang Zi supported each other forward, they were only 2,500 meters away from Cassini Station, there were no obstacles on the half-foot lake, they could walk in a straight line.

"Dabai, what is Chef doing at this time?" Jiang Zi asked.

"Mr. Wan Kai is watching the ball game in his room." Dabai replied, "It is the critical moment of deciding the winner, and it is recommended that you do not disturb him." ”

"Watching a fart ball game, we're working hard outside, he's watching the ball in the house?" Jiang Zi said, "Pick him up for me!" ”

There was silence in the headphones for a few seconds, and Wan Kai's voice rang out: "Stationmaster! Lao Liang! Are you all right? When will I be able to come back? ”

"It's not good." Jiang Zi pulled Liang Jing and trudged hard in the lake, staring at the path map on the screen to make sure he was on the right route, "I encountered a howling, the car was scrapped, we are walking in the half-foot lake, there are still five miles away from you, at least half an hour to walk." ”

Wan Kai was taken aback.

"People don't matter, do you? You and Lao Liang weren't hurt, were you? ”

"I didn't hurt anything, but I was scared enough." Liang Jing said, "I finally saw what a banshee howling is, it's terrifying. ”

Wan Kai laughed, "It's good to get used to it, I haven't been chased by a banshee on Titan, it's an incomplete life." ”

"What about acquiescence? How's the tacit give? ”

"Mo Yu's condition is very stable, she is completely out of danger, I removed her from the ICU, and the girl is now sleeping in her room." The chef said, "That girl slept like a pig, and I think she's gained a few pounds in the past two days." ”

Jiang Zi Liang Jing and Wan Kai walked and talked, they all needed other people to dispel this terrible loneliness, the further they went, the more Jiang Zi and Liang Jing felt cold and lonely, the never-ending lake and thick fog, only the path map on the helmet mask was telling them that this was the right direction, Jiang Zi and Liang Jing were talking louder and louder, this mentality was like singing songs to cheer themselves up when walking alone at night.

"It's almost there, maybe a few hundred meters away." Jiang Zi said, "We're tired, we have to rest well when we go back, are you ready to eat?" ”

"It's been ready for a long time."

Liang Jing stared at the road map on the mask, the point of light that represented himself was close to the end, he finally breathed a sigh of relief, he was about to return to the station, he couldn't wait to pounce on the soft sofa and bed, and massage his soreness and numb hands and feet.

Liang Jing looked up, expecting to see the tall buildings of Cassini Station appear in the thick fog.

"Don't do any more love fried eggs for dinner." Jiang Zi said, "You can be the king of the dark cuisine world with this dish." ”

"I prepared sweet and sour pork ribs for you, as well as white chopped chicken......"

The communication suddenly blurred, and Wan Kai's voice quickly disappeared into the noise of electricity.

"Wan Kai? Wan Kai? ”

"Chef?"

Understanding and Jiang Zi shouted at the same time as he pressed his helmet.

"Wan Kai! Wan Kai! Chef! Great? What's going on? Great? Great? ”
