Tang Yue and Mai Dong waited all night, until the sun rose and the sky was bright, and the old cat did not send any news.

Only then did Tang Yue confirm that the old cat was really wrong.

But what can go wrong with an old cat? It's an experienced resident crew member of the Kunlun station, driving a rover, carrying enough solar panels, not oxygen, no fresh water, and no food, how can it run into such trouble on uninhabited Mars? There's not even a roadblock in this hellish place.

Tang Yue became more and more anxious.

"No, Tang Yue, there is no response in the channel." Mai Dong tried to call the Martian stray dog again, "Still can't contact Mr. Cat." ”

"What could go wrong with it?" Tang Yue pinched the pen in his hand, mechanically pointed the tip of the pen on the table, he imagined in his mind all the difficulties that the old cat might encounter, and overturned them one by one, "Even if you encounter unsolvable troubles, can't you connect a letter...... Could it be that the car overturned? ”

The old cat, the god of the stroller in the autumn famous mountain, will there be a day when the car rolls over?

Tang Yue couldn't imagine how to drive the Martian stray dog over, the stray dog is an electric tractor that is as slow as a turtle climbing, with large wheels, low chassis, low power, and natural insulation with all kinds of wonderful stunts, and it can surpass the flying pigeon bicycle at full speed, and the control mode is simple like a bumper car in an amusement park, even if you find Schumacher to let him sit in the cab, he can only stare at the throttle of this old scooter.

Unless you deliberately push it into the pit, stray dogs can't turn it over.

"Unless it overturned and broke the communication antenna, it wouldn't have been able to go so long without contacting us." Tang Yue turned his head to look out the window, at this time the old cat was still ninety kilometers away, this distance was nothing on Earth, but it was like a moat on Mars - Tang Yue thought about going to find the old cat himself, but the life support system did not allow him to do so.

Wearing the Mingguang armor, Tang Yue could only be active outdoors for eight hours at most, and the power and oxygen would be exhausted if it took a long time.

Eight hours obviously can't cross 90 kilometers on foot, and Tang Yue will only hang on the way halfway when he goes out rashly.

The loss of contact can be big or small, to say that it may be just that the communication antenna on the Martian stray dog is malfunctioning, the old cat and the Mars rover itself are safe and sound, and they are rushing back to Kunlun Station at full speed, but it is possible that even the cat and the car have an accident, the old cat drove the stray dog off the cliff, and the car was destroyed and the cat died.

There was only endless noise in the communication channel, Tang Yue turned the knob and searched repeatedly on various frequency bands, but found nothing, this kind of silence that sank into the sea was the most disturbing, and he couldn't even receive the shortest call for help, which meant that the other party was either not online or no longer alive.

"What the hell is wrong with you, this damn cat...... Send me a comma! Send me a comma......"

Tang Yue got up and paced back and forth in Kunlun Station, his hands moving his joints, he rubbed his hands repeatedly, looking out while warding off the cold.

Tang Yue...... Maybe Mr. Cat's communication system is just malfunctioning, and it's on its way back? Don't be too anxious...... Mai Dong comforted him, "wait." ”

It's really worrying to wait like this, but Tang Yue can't do anything, he can only stay in Kunlun Station, circling like a bear in this area of dozens of square meters.

The OGS cabinet is spitting out cold air, and the indoor temperature at Kunlun Station has dropped to minus 20 degrees Celsius overnight, and the temperature may rise after the sun comes out, but it is also fluctuating below zero.

Tang Yue had already put on all the clothes he could wear, wrapped in a blanket and living the RTG.

"Calm down...... Calm down! Tang Yue sat down again and took a deep breath, "Mai Dong, you calm down first, Mai Dong, you calm down first, you can't solve any problems in a hurry." ”

"I'm calm, it's you who need to be calm, Tang Yue." The girl blinked.

"Okay, okay...... I'll calm down first. Tang Yue pressed his forehead and forced himself to calm down, "Let's now analyze the situation that the old cat may be facing at the moment, and see if we can help." ”

Mai Dong nodded.

"It lost contact with us, and one thing for sure was that there was a problem with its communication system." Tang Yue said, of course, it is also possible that the old cat has a brain convulsion and disappeared, and deliberately does not contact the space station, but this possibility is very small, and Tang Yue does not consider it.

"What caused Mr. Cat's communication system to malfunction?" Mai Dong asked.

"The communication system on the Martian stray dog is the backup of the Kunlun station, which is very reliable, the robustness of the whole system is very high, and the use time of the Martian stray dog is almost equal to that of the Kunlun station, but the communication system has never had any problems." Tang Yue replied, "Just the day before the old cat set off, I also checked the stray dogs, and the communication system at that time was normal...... So the likelihood of a spontaneous failure is low. ”

"So it's an external factor?"

Tang Yue nodded, "There is a high probability that it is due to external forces, such as strong mechanical impact, high temperature, strong radiation, and man-made destruction......

Tang Yue and Mai Dong both had an ominous premonition in their hearts, since the cause of the failure of the communication system was external factors, and the communication system was installed inside the rover, and it was damaged by a violent impact, then wouldn't the external Martian stray dog itself and the pilot old cat be more dangerous?

"On the surface of Mars, high-temperature radiation and man-made sabotage can be ruled out, and the most likely is a rollover." Tang Yue continued, "If it really overturned, then it would definitely not be able to push the heavy Martian stray dog right, so the most appropriate way to deal with it at that time should be to abandon the rover and return to Kunlun Station on foot alone...... But the old cat also has to be charged, so it also has to carry enough battery plates with it...... Damn it! ”

Mai Dong held his breath.

If Tang Yue's inference is correct, then the old cat is dragging the solar panels at the moment, walking alone in the wasteland.

"But it's just a possibility, it's just a possibility!" Tang Yue shook his head and eliminated the assumptions in his mind, "If the severity of the accident is higher than we thought, then it is very likely that the old cat will be destroyed along with the rover - it may have escaped but was severely disabled and incapacitated, and it may have died on the spot...... Damn it. ”

The second assumption is too terrible, Mai Dong can't imagine, what is a severe disability and incapacitation? Did you break your legs and lie there helplessly waiting to die?

"Mai Dong...... Mai Dong! ”

"Huh?" Mai Dong was startled and came back to his senses.

"We can't wait any longer, we have to understand the current condition of the old cat!" Tang Yue said, "You have to help me!" Do you hear that? Only you can help me! ”

"How can I help?"

"First we need to find the old cat!" Tang Yue replied, "There is a camera on the space station, and you are in orbit to scan the bottom ......"

"But the scanning telescope and high-precision camera are all in the Dawn module, and they have all been destroyed."

"In addition to the Dawn module, there are cameras in other cabins!"

"Yes...... However, it is not used to survey the surface, and the accuracy is not high. "And you can't plan path scanning, and you can't automatically identify them." ”

"It doesn't matter if we can't scan automatically, we'll do it manually." Tang Yue pointed at Mai Dong and then at himself, "It doesn't matter if you can't automatically identify it, let's use our eyes!" ”

"We all have to find the cat!"
