The old cat squatted on the floor in front of the OGS cabinet, clutching a screwdriver in his paws and staring at the motherboard with two cat's eyes.

Tang Yue rummaged frantically in the hall of Kunlun Station, and finally he threw a cup lid on the table and sighed, "No, I've searched all the places I can find, and I can't find a replacement at all...... I don't know where the last replacement chip is, most likely it may have been crushed and compacted and brought back. ”

All the garbage generated in Kunlun Station will be taken away after treatment, this so-called treatment is crushing and compacting, first violently crushed, and then compressed into tens of centimeters square, semiconductor chips such a delicate and delicate thing can not survive this level.

"What about other alternatives?" The old cat turned his head.

"Where are there any alternatives?" Tang Yue shook his head, "In this broken shack, everything is manual, and Gree air conditioners are considered high-tech...... Now it's just a matter of seeing if you can find a working processor in the workstation chassis. ”

Tang Yue and the old cat began to disassemble the computer case.

The most important thing in the workstation chassis is the processor, but there may not be a chip suitable for the OGS cabinet temperature control system, every processor in the Kunlun station is highly specialized, and it cannot be mixed, Tang Yue knows this, he actually doesn't have much hope, but he has to find it before he is willing to die.

"Can this piece be demolished?"

"No, if you dismantle the computer, it will be scrapped."

"Where's this one...... Hell, it can't be plugged in at all! Old cat, do you have an electric soldering iron and solder? ”

Tang Yue and the old cat were busy for more than two hours, they disassembled the chassis of the workstation, hoping that there could be some parts on it to repair the OGS cabinet, the final result was very disappointing, but it was also expected by Tang Yue and the old cat - the processor used in the OGS cabinet and the workstation are not of the same type at all, and the interface is not uniform.

The old cat and Tang Yue sat on the floor and put the chassis of the workstation back.

"It's getting colder." Tang Yue wrapped the clothes and blankets on his body tightly, and retracted his feet into them, "How hot is the temperature now?" ”

"-3 degrees Celsius." The old cat replied, "It's still slowly declining." ”

"It's cold." Tang Yue shuddered.

"But the temperature here is still 50 degrees Celsius warmer than the outside." The old cat tapped the table leg with a wrench, "The shell of Kunlun Station helps you retain most of the heat, but if you continue to follow this trend, by dawn, the indoor temperature at Kunlun Station will drop to minus five degrees, and by tomorrow night, the temperature here will drop to minus fifteen degrees Celsius." ”

Tang Yue shuddered, if the temperature control system cannot be repaired, then the indoor temperature at Kunlun Station will continue to drop, the temperature here will drop to minus fifteen degrees tomorrow night, then it will drop to minus twenty-five degrees the night after tomorrow, he can't imagine life at minus twenty-five degrees Celsius, under that temperature, the plant will not survive at all, the plan to plant tomatoes can be regarded as a soup, and he will be wrapped like an Eskimo, or put the bright light armor on his body forever.

What's even more terrifying is that the temperature will continue to drop, and the heat conduction will always be transmitted from high temperature to low temperature until the temperature inside and outside Kunlun Station is the same.

The lowest temperature outside can break through minus 80 degrees Celsius, a temperature that Tang Yue has only seen in a liquid nitrogen cryogenic freezer...... He doesn't think he'll survive in a liquid nitrogen freezer.

"Without this processor, can you fix the temperature control system?" Tang Yue couldn't sit still.

"The processor is at the center of the temperature control system." The old cat plugged the processor back into the card slot of the motherboard, "The temperature detection unit transmits the information to this chip, and then it gives feedback and gives instructions to the temperature adjustment unit, it is the brain, without the brain, the temperature control system cannot work." ”

"Workstation hosting?" Tang Yue said, "Simple negative feedback automatic control, the performance of the computer is more than enough!" ”

One person and one cat began to try to connect the temperature control system with the workstation, Tang Yue found scissors and tape, and the old cat copied the soldering iron and solder, and used a useless data cable to cut the interface and take out the copper wire.

They made a very rudimentary data interface, one end plugged into the computer case, and then two extremely thin copper wires were carefully soldered to the pins of the motherboard, one for data input and the other for data output.

When everything was ready, the old cat turned on the computer and entered the test program, "Ready?" ”

Tang Yue nodded, opened the OGS cabinet, "Start heating up!" ”

The two were silent for a few seconds.

The old cat stared at the screen, his wrung eyebrows slowly collapsing, "No response...... Failed. ”

"." Tang Yue was very disappointed, they were busy all night, and in the end they were all doing useless work.

In the simple shack of Kunlun Station, there are only a few things with a higher degree of automation, if it is on Earth, Tang Yue can find a computer city to repair the temperature control system of the OGS cabinet, but on Mars, they can't get a simple chip.

Tang Yue felt more and more cold, the clothes and blankets on his body couldn't bear it, he turned around and went back to the crew compartment, moved the sleeping bag out, and then got into the thick sleeping bag, lying on the ground like a big caterpillar, only one head was exposed.

The old cat pinched the processor and stared at it, not saying a word.

"Old cat, do you know the Ötzi Iceman?" Tang Yue asked.

"Ötzi Iceman?" The old cat replied absentmindedly.

"A very famous mummy, it is an ancient man 5,000 years ago, who died in a glacier in the Alps, and the body was preserved intact by the ice and snow, and it was not found until the nineties of the twentieth century." Tang Yue explained, "The cause of Ötzi Iceman's death was an arrow wound, he was hit by an arrow in the shoulder, and it is possible that he died while fleeing, so it is possible that he died in a chase." ”

"Oh." The old cat squinted his eyes and looked at the chip in his hand.

"If the temperature control system can't be fixed, then I'll probably end up like him, a mummy lying in a sleeping bag." Tang Yue sighed, and the white water vapor disappeared in the dim light, "You said that if some intelligent beings discovered me in a million years, would they also display me in the glass case of the museum, labeled Martian Iceman?" ”

"Possibly." The old cat responded without being salty, did not look away, and looked a little distracted.

Tang Yue was a little surprised, why was this scab cat silent at this moment? Nothing is interesting.

"Old cat?"

"Shut up." The old cat's pupils slowly expanded, reflecting the processor in his paws, "I don't have the slightest interest in what Ötzi Iceman and Martian Iceman are, and I don't care if you will be displayed in a glass case in a museum for a million years, and I don't think the label on your body will be a Martian Iceman, but a Martian Ice Monkey...... I'm thinking about the problem, a very important question. ”

Tang Yue was stunned.

"What's the problem?"

The old cat twisted his head and put the processor on the table, "How to fix the temperature control system of OGS." ”

"The problem is that it can't be fixed anymore, haven't we already used all the methods?"

The old cat tilted his head and said, "No! ”

Tang Yue was taken aback, "What? ”

The old cat slowly erected a paw, "There is another way...... One last resort! ”
