"Old history."

"Huh?"

"Are you going to come out again after you go back this time?" Liu Peijia's tone was very casual, his shoulders swayed with the pace of the walking car, he did ask casually, I don't know whether it was deliberate or unintentional, Liu Peijia behaved casually, as if he was just talking to others on the bus, "Or retire and quit?" ”

"Retired." Stong looked ahead, put his hands on the steering wheel, it was rare to have a steering wheel in this era, "Don't do it, work hard, it's enough to do one thing in a lifetime, I will retire when I go back." ”

"What can you do when you go back?" Liu Peijia said, "Rotten life, what else can you do besides driving a boat?" ”

"And it can show people." Steng raised his hand and rubbed the front windshield of the walking car, there was a dark stain on the glass, but he wiped it with his finger and found that it was not on the inside, the windshield of the walking car was two centimeters thick, the three-layer structure was quite solid, and the internal interlayer could heat the surface temperature of the glass to 20 degrees Celsius, and the rain and snow on Titan would evaporate immediately when it touched the glass - the low ambient temperature also had such an advantage, saving the wipers.

Stong took a closer look at the dark stain on the glass, and saw that it was in the glass interlayer, probably a broken heating wire.

"Guarding the streets or something, there will always be a place where someone needs to work."

"Now you don't need to be a doorman to sweep the streets." Liu Peijia said, "Middle-aged men are not as good as dogs. ”

"We're not as good as dogs for a long time." Stun said leisurely, "If there is still a place on Earth and Mars, how can we be sent to this place of the hell?" A good horse with a good saddle, a good ship with a good sail, and as for our broken ship, it can only be matched with us old things...... Great? Dabai, how far are we from Half a Foot Lake? ”

"There's still 1,600 meters to go." Dabai's voice sounded in the headphones.

The crawler made a scraping rustle as it crawled through the snow on six short legs, and the engineers had anticipated the situation when they designed the bike, where neither the wheels nor the tracks were capable of moving in the heavy snow in a low-gravity environment, and only long legs could crawl around the planet.

The car's high beams swept around, and the car walked in the snow like a sneaky iron cockroach walking in flour.

The car's connection to Cassini Station was unstable, and Stong had to drop a communication buoy every time he walked the distance.

"It's snowing so much, it's a shame it's nighttime, but if it's daytime, we should be able to see the widest snowfield in the world...... Can you imagine a flat snow field the size of hundreds of square kilometers? ”

Shi Teng's upper body leaned forward slightly, looking into the distance.

"Actually, the walking cart should be loaded with a sled." Liu Peijia said.

"It's useless to load up the sled." Ston shook his head, "It's all fluffy snow, it's not compacted, you think you can slip up?" ”

"We're out of Cassini Station." He hammered the center console again, and the millimeter-wave radar of the walking car was almost destroyed, the display flickered, and received all kinds of chaotic echoes, "What's wrong with this radar......

The walking vehicle is equipped with a millimeter-wave radar on the body of the vehicle, which is used to detect the surrounding environment in low-visibility conditions, and it can simultaneously obtain the three-dimensional spatial information and velocity vector of the target.

Under normal circumstances, the walking car can construct a three-dimensional image of its surroundings while moving, which relies on thousands of electroscan millimeter waves radiating to the surrounding area, which are reflected back after touching the obstacles, telling the walking car what they have touched - although the walking car is blind, but a blind man with thousands of guide sticks, each stick is nearly infinite in length, it pokes all the sticks in all directions at the same time in one second, and each stick will touch a point. An almost infinite number of points can be built into a surface, and a walking car can tell you where you are.

But the car's radar is gone, its stick is not working.

"How far can this radar be effective?" Liu Peijia glanced at it and frowned, it may be because of the heavy snowfall, there are always large patches of virtual shadows on the monitor.

"Five kilometers at most." "But the radar must be broken, and the clutter can't be filtered......

"And what is this?" Liu Peijia pointed to the large halo on the monitor, "Such a large volume is like a mountain." ”

Stern's tilt of the head showed a large white halo on the radar display, the edges were blurred, and it was about two kilometers to the northeast of the walking car.

Liu Peiqi raised his head and looked out the window, he couldn't see anything in the snowy night with extremely low visibility, but according to the radar, there was a very large object two kilometers ahead.

Liu Peijia estimated the size of the shadow, and the length of this thing must be nearly 100 meters.

"It's snow." Shi Teng patted the center console hard, and the monitor flashed and went out, "This broken car, it's not saved, it stands to reason, whether it's rain or snow, or clouds and fog, it should be filtered out, but there's something wrong with this radar, I don't know what's wrong, and the clutter can't be filtered out......"

Liu Peijia helped to shoot the center console together, and the monitor was lit up again.

This time the radar echo was gone, and it was empty where the shadows were supposed to appear.

Conversely, a few kilometres southwest of the pedestrian car, there was a large shadow.

"See? This radar is a convulsion, and it is displayed randomly. Stong pouted, "There's something here for a while, there's something there, I'm surprised." ”

Shi Teng and Liu Peijia chatted with each other, and the walking car staggered into the depths of the night.

The other side.

"How are they?"

"The signal is pretty stable." Mu Mu stared at the computer screen, "Da Bai is reporting the point, the walking car is still four hundred meters away from the half-foot lake, so far, everything is going well." ”

Dabai was monitoring the movement of the walking car, and after Dabai resumed his work, Mumu and the others gave it most of the tasks, and in the current situation, AI is obviously more reliable than the human brain.

Relying on the communication buoys scattered around Cassini Station, Dabai can impose his orders on all machines, and although it is no longer as powerful as it once was, it is still strong enough to serve as the backbone of the crew.

"Dabai, how much power is left in the walking car?"

"Seventy-nine percent." "According to the current use rate, the walking cart is expected to work for three hours and five minutes." ”

Mu Mu nodded and leaned back.

Ge Zi and Dai Yue had already gotten into their sleeping bags to rest, and now she and Zhuo Zhi were standing guard.

Mu Mu is a communications engineer on the prospecting ship Hades and is known for its long standby time.

"Dabai, you have to bring them back to me safe and sound." Mu Mu looked up at the roof of the laboratory and exhaled, "Who made you in the first place?" ”

"That was a long time ago." Dabai said.

"Whoever made you." "They all hope that one day you will come in handy, and if we can be successfully rescued, I will bring you back to Earth and put you in a museum...... Dai Yue? What are you going to do? ”

Dai Yue got out of his sleeping bag and was about to go out with his notebook.

"People have three urgencies." Dai Yue said, "Please give me a bucket." ”
