Tang Yue sat in the passenger seat, the Martian stray dog was jolting forward in the dark, to be honest, Tang Yue had no bottom in his heart, at least he was completely disoriented, no one could accurately determine the direction in the state of complete obstruction, at first he still knew where the south was and where was the north, but after the rover made two turns around in the dark, Tang Yue was completely dizzy.

However, the old cat showed confidence and did not hesitate to turn the car at all.

The Martian Stray Dogs' headlights can only illuminate a distance of about five meters in front of them in a dust storm, and they are at least thirty kilometers away from the target.

"Ditch!"

"See." The old cat clenched the steering wheel, "But it's not deep, let's run over it directly." ”

The Martian stray dog galloped in the dark dust storm at the highest speed, this was an almost crazy behavior, Tang Yue and the old cat could not see the situation five meters away, once there was any obstacle blocking the way, with the clumsiness of the Martian stray dog, there was no time to react.

"Why don't your eyes have night vision? Are you a beggar's version? Didn't have an option at the factory? Tang Yue asked loudly.

"Don't talk nonsense!" The old cat pointed to his eyes, "My tricks are much brighter than yours!" ZEISS lenses! Huawei P400! High-performance low-light night vision! ”

"Then you can't see anything!"

"What kind of night vision devices do you use in this damn weather, you have to be blind!" The old cat shouted, "It's a sandstorm!" There is a huge amount of dust suspended in the air, almost blocking the light! Night vision devices are used for a fart! ”

"Ditch! Ditch ditch ditch ditch! ”

"See!" The old cat yelled and slammed the steering wheel, and the body of the Martian stray dog immediately moved sideways, avoiding the deepest part of the ravine in a rather thrilling posture, the wheels ran over the sunken ground, and then bounced up again, Tang Yue was so pinned out of the seat that he hit his head on the cab frame.

"Have you read Wang Xiaobo's "Red Breeze Running in the Night"?" Tang Yue leaned on the frame of the car and shouted.

"When has it been since you were still running around at night? Can you divide the time and occasion without paying attention? We are now wild dogs running at night! The old cat also shouted, while slamming on the brakes and steering at the same time, a giant basalt more than two meters high suddenly appeared in the light, Tang Yue and the old cat were shocked, if it hit head-on, it would be a reproduction of the tragedy of the Titanic, the Martian stray dog showed its reliable side at the moment, relying on the strong grip of the wheels in situ Shenlong swinging tail, a disabled old husky ran out of the demeanor of the German black-backed shepherd.

"It's a pity that there is no red whisk and no Li Jing here, and there is no love story of escaping together, only one person, one cat and one dog who lives in the world!" The old cat avoided the obstacles in the middle of the road and continued to accelerate, and the stray dog surged forward in the storm.

They're headwinding against the wind, and the sand is coming in front of them, but the Martian atmosphere isn't dense enough to create significant air resistance, and the stray dogs' turtle speed doesn't need a streamlined shell to reduce drag.

"I mean, we can pray to Mr. Wang Xiaobo to bless us! He will bless us! Tang Yue held on to the frame of the car, if it wasn't for the seat belt that tied him tightly to the seat, he would have been turned upside down, the old cat didn't know what nerves he had, he picked some potholes and walked on the ground, the rover jumped all the way, and at the most exaggerated time, it almost left the ground at the same time.

"Downhill! Downhill ——! ”

The head of the Martian stray dog slammed down, Tang Yue's eyes widened, and there was a steep slope in front of him, I don't know how long, the lights couldn't see the bottom of the slope, and the Mars rover took him and the old cat all the way down,

"Don't shout, beware of biting your tongue!" The old cat gritted his teeth and replied, "I'm afraid Mr. Wang Xiaobo won't be able to help us at this time." ”

"Then ask Lu Xun, Mr. Lu Xun once said that Tang Yue and the old cat will definitely be able to successfully reach their destination!" Tang Yue said, "There will always be someone who can bless us." ”

"When did Mr. Lu Xun say this?"

"At half past two in the afternoon of October 20, 1892, Mr. Lu Xun was studying in the Sanwei Book House and skipped class when he walked over the low wall on the side of the road in Baicao Garden!"

"How do you confirm it?"

"How do you falsify?"

The Martian stray dog rushed down the slope, followed by the salt lake-like flatland, and Tang Yue noticed that the gravel on the ground was getting smaller and smaller, and the amplitude of the body shaking was getting smaller and smaller.

"Do you know how far we've run?" The old cat asked.

"You drove the stray dog like a roller coaster, how do I know how far I've run?"

"Five kilometers." The old cat replied, "From the time we set out until now, we have walked five kilometers and a quarter of a kilometer to be exact, and we are still twenty-four kilometers and seven hundred and fifty meters from our final destination, and that coordinate is now about fifteen degrees east of us directly in front of us, so we need to deviate slightly to the left." ”

Tang Yue was taken aback.

The old cat swore by it, and the distance was calculated quite accurately, not like it was fooling him, but how did it do it? In such harsh weather and geographical conditions, the sun and stars cannot be seen, and the fingers cannot be seen when the hand is stretched out, the sextant and the star catalog are useless, and any accurate measuring tools have to be blinded.

"We bring our own rulers, wheels." The old cat explained, "The diameter of the wheel of the Martian stray dog is about 0.75 meters, and one turn is 2.36 meters...... Two...... One! Listen carefully! ”

Tang Yue sat on the chair, as soon as the old cat's words fell, he heard a faint thud, it sounded like a certain spring was compressed to the limit, and then bounced away in an instant, this sound was not transmitted through the air, but along the metal body frame into his ears, the sound was extremely faint, it was difficult to detect.

Tang Yue continued to concentrate, this voice was really regular.

"From the time we set off to the present, the wheels of the stray dogs have turned a total of 2,240 times, excluding the twists and errors in the middle, which is five kilometers." "The stray dog's battery has 70 percent power left, which is barely enough, and it should be able to get us to our destination." ”

"Does this lamp drain power?" Tang Yue asked.

"Quite a power drain."

"Can you turn off the lights?"

"Turn off the lights, we'll all have to go into the ditch." The old cat shook his head, "These dog eyes are the only thing in our hands that can deal with dust storms, in this kind of ghost weather, night vision devices are useless, infrared ones are useless, and shimmering ones are useless, what we need is light bulbs!" Big bulbs! The bigger, the better! In the face of sufficient brightness, any weather is vain, and God says there must be light! ”

Tang Yue glanced down at his Mingguang armor, the remaining power of the battery was still in the green safety range, and the independent working time of the extravehicular suit was only eight hours, and within eight hours, he had to complete this task, otherwise he would die from the extravehicular suit running out of power.
