Tang Yue looked in the mirror, wearing a silver tin foil thermal blanket on his body, squeezing his eyebrows and eyebrows, and dancing his teeth and claws.

He combed his hair back hard into a big back, trying to put on the style and demeanor of Leonardo Dioccapri or Chow Yun-fat.

"Old cat, don't you think I've always looked like that...... That old-school Hong Kong actor? The handsome one who exploded acted in a police movie with Jackie Chan. Tang Yue recalled, "It's called Wu ...... Wu ......"

The old cat sat down behind him and glanced at him.

"Wu Mengda."

Today is Tang Yue's ninety-eighth day on Mars.

It has been three months since the disappearance of the earth, the earth is still silent, the communication system of the Kunlun station is turned on day and night, but still does not receive any information from the outside world, in the past three months, the old cat has spent a lot of time and energy guessing and analyzing the cause of the disappearance of the earth, and trying to track the trajectory of the Orion 1 spacecraft.

Orion No. 1 was the spaceship that Lao Wang and the others were on, and it had to return to Earth a few days earlier than Tang Yue.

Tang Yue should have returned to Earth on that spacecraft - it is very rare for the Mars scientific expedition team to return to Earth in two batches, but there is still an important scientific research and observation mission to be completed in Kunlun Station, and the old cat alone is short of manpower, so Tang Yue stayed to assist it, and when the mission is completed, Tang Yue will return to Earth in the Orion 2 spacecraft.

At the same time, he also served as the escort of Orion 2, and a large number of active experimental samples in the Orion 2 spacecraft needed special care.

Who would have thought that the delay in leaving for a few days would actually save Tang Yue's life.

Orion 1 and 2 are more than 10 years of service of the old spacecraft, outstanding achievements, but old, originally according to the earth's plan, after the end of this mission, Orion 1 and 2 spacecraft return to Earth together, will be retired together, the next time as a carrier of the Mars expedition spacecraft, will be the new Orion 3 and 4.

This delay of a few days also saved Orion II.

If it had departed at the same time as Ship One, it might have disappeared by now.

"Mr. Cat! Tang Yue! Mai Dong popped up on the screen, "Good morning! Have you had breakfast? ”

She was still as energetic as ever, and after three months, her hair grew longer, and Mai Dong wore a simple ponytail.

"Good morning, Miss Mai Dong." The old cat sat at the other end of the hall, waving his paws from afar, and he had to groom every morning when he got up.

"Good morning, girl." Tang Yue nodded, "How many sunrises are you over there?" ”

"The seventh."

"What did you eat this morning?"

"Hmm...... Tuna, cheese and orange juice. The girl's fair face and neck were sweaty, and she stroked the hair from the corners of her forehead, "I just rode five kilometers. ”

"What a petty bourgeoisie."

"Tang Yue, what did you eat this morning?" Mai Dong asked.

"Me? My breakfast is a mix of East and West. Tang Yue thought for a while, "Laoshan white flower snake grass water with canned Swedish herring." ”

Three months ago, Tang Yue sent enough supplies to the United Space Station, and Mai Dong's food was not to worry about for the time being, but energy and nutrition were only a part of maintaining good health after all.

Human beings are creatures that evolved on the earth, and their body structure has long been adapted to the gravity of a G, and a long-term weightless environment can bring various problems, especially the muscular, cardiovascular, and sensory nervous systems.

In long-term space missions, the physiological and psychological changes of astronauts have always been a hot research problem, due to the long-term microgravity state, so the loss of calcium in human bones will be accelerated, bone decline, gravity-resistant muscle groups will be in a state of disuse for a long time, muscles will continue to atrophy, the number of red blood cells in the blood will also decline, resulting in a weakened cardiovascular regulatory ability.

These problems were highlighted during the long mission period of the Mars landing, which seriously threatened the health of the astronauts.

Medical experts on Earth have specially designed a set of physical training programs for the Mars mission to combat the decline in physical fitness in a weightless state, and the Orion spacecraft and Kunlun station each have a set of training equipment, requiring the team members to do a full amount of training every day, such as Tang Yue, he has to run three kilometers on the treadmill every day.

There is still a bit of gravity on Mars, and there is complete weightlessness on the United Space Station, and Mai Dong needs a greater amount of training than Tang Yue.

"Tang Yue, what are you going to do next?" Mai Dong asked, "Do you want to move solar panels?" ”

Tang Yue nodded, he took off his robe, changed into clothes, and prepared to wear the Mingguang armor.

More than 40 solar panels have broken one, three months ago in the sandstorm, they didn't have time to put the panels back indoors, the next day Lao Mao and Tang Yue found that the power of two panels had dropped, the two worked hard to repair one, but the other one was really not repaired.

The old cat deduced that this was due to the fact that the battery board was exposed to the low temperature environment for too long, coupled with the sand and dust invading the internal circuit of the battery board, resulting in a short circuit.

Now they still have forty batteries left, but fortunately one less solar panel will not affect the normal operation of Kunlun Station, the old cat warned Tang Yue that ten is a cordon, once the number of damaged panels exceeds ten, then the normal power supply of Kunlun Station cannot be guaranteed, and they will have to turn off some functions in Kunlun Station.

Food, fresh water, batteries, don't know which one runs out first.

This is a bit similar to the short board effect, Tang Yue's remaining life and the length of that short board are equal.

"After the solar panels were moved, I had to check the status of the various systems at the Kunlun station, which was just a bunch of trivial things." Tang Yue said, "If I move fast enough, I may still have time to sit at the door of Kunlun Station and watch the sunset." ”

"What is the sunset like at Kunlun Station?"

"Sometimes it's red." Tang Yue replied, "Sometimes it's blue. ”

"Blue?" Mai Dong was surprised.

"The old cat said that the sun looks blue because the dust at the bottom of the Martian atmosphere scatters blue light with a shorter wavelength." Tang Yue shrugged his shoulders and passed the old cat with his clothes in his hand.

He saw the cat sitting on its lap, paws on its knees, motionless, eyes closed.

"What are you doing?"

Tang Yue poked the cat's head.

"Take your paws away." The old cat remained silent and whispered.

"I'm a hand, you're a claw." Tang Yue corrected.

"In my opinion, you're the five-toed, hairless, bare paws of primates." The old cat countered, "I am meditating in meditation and understanding the truth of the world. ”

"Meditate and go to Zen?" Tang Yue sneered, "What kind of Zen are you participating in?" What truth has come to be realized? ”

"I am participating in the Great Dao of Heaven and Earth, the Supreme Principle of the Universe." The old cat slowly opened his eyes, his expression was flat, like a high-level cat, "For example, the truth about why the Orion One spacecraft disappeared." ”
