The old cat dragged Tang Yue in, closed the hatch, removed the life support system of the Mingguang armor, and pulled him out of the spacesuit.

The old cat asked Tang Yue to sit down against the wall to rest, then squatted in front of him and pinched Tang Yue's toes hard, "Foot cramps?" ”

"Pinch your uncle, it hurts!"

Tang Yue shrank his feet, slapped the old cat's paws, pinched his calves, and slowly massaged his muscles.

"It's okay." The old cat spread his hands, "I thought you were paraplegic and half-paraplegic...... If you're really paralyzed, I'll throw you out to fend for yourself. ”

"Can you talk about humanitarianism?" Tang Yue rolled his eyes.

"It's humanitarianism for me to throw you outside, you can't live more than three minutes outside Kunlun Station, you die quickly, and there is no pain." The old cat said, "Believe me, you won't think about the days of collapsing and slowly dying and rotting in Kunlun Station, this kind of life is really better than death." ”

Tang Yue kneaded his knee joint, he just had a sudden pain in his knee, and he stumbled under his feet before falling to the ground.

The old cat walked around him twice, leaned over and lifted Tang Yue's arm, looked up and down carefully, a pair of cat eyes turned around, and sniffed.

"What are you doing?" Tang Yue was furious by it.

"Keep your head down." The old cat pressed one paw on the top of Tang Yue's head, pressed his head down, and then pulled up the collar of his clothes.

"Look up." The old cat dragged Tang Yue's chin, pushed his head up, leaned over and touched Tang Yue's neck, and looked carefully, as if he was looking for a suitable place to put a knife before killing a pig.

"Holy, what the are you doing......"

Before Tang Yue's words were finished, his face was pinched by the old cat.

"Ahh

Tang Yue obediently "Ah-".

The old cat pinched one of Tang Yue's front teeth, stared at it for a long time, nodded, let go of Tang Yue, took a step back, sat down in the chair, and raised Erlang's legs.

"There's something wrong with your body."

Tang Yue was confused, "What's the problem?" ”

"Judging from the current symptoms, the calcium and vitamin C supplements in your body are insufficient, I just checked it, you have symptoms of subcutaneous bleeding, bruises on your back and arms, and swollen gums, which is a typical manifestation of vitamin C deficiency, do you have joint pain? This may also be caused by a lack of vitamin C. The old cat replied, "Calcium deficiency can lead to fatigue and cramps, and spasms in the limbs." ”

The old cat was serious, Tang Yue raised his arm, and sure enough, he saw bruises and bleeding spots on the skin on the inside of his arm, which he thought was bumped into when wearing the Mingguang armor.

Tang Yue is not from a medical or physiological background, he is not as sensitive to the details of nutritional supplements as the old cat, in the current situation of lack of food and clothing, Tang Yue can only ensure that there is food every day at most, and the energy supplement can be satisfied, as for the details of iron, zinc, copper, selenium, eighteen trace elements and eight essential amino acids, it cannot be taken into account.

The team doctor in the previous expedition team was Maxwell Thorpe, commonly known as Lao Mai, an expert in aerospace medicine and physiology, and he has always been responsible for the nutrition of astronauts during the Mars landing mission. The Mars landing mission is a two-year long-term spaceflight, but the crew of the Orion spacecraft cannot receive regular supplies from Earth like the ISS, and it is difficult to get treatment once they are sick, so the physical health of the expedition team members has always been a problem.

Lao Mai has formulated a very strict physical health care plan for the players, including what to eat, how much to eat, how to eat, and physical training methods, which are to prevent calcium loss, osteoporosis and muscle atrophy in the body.

"How many vitamin tablets are left?" The old cat asked.

"Half of it was given to Mai Dong, and the rest was almost eaten." Tang Yue replied.

The lack of vitamins was obviously a problem with the food, Tang Yue recalled his recipes for nearly a month, the first two months of his food was quite abundant, but as the large pieces of rehydrated food and canned food gradually ran out, Tang Yue had to start eating a lot of energy bars and compressed biscuits.

The vitamin content of energy bars and compressed biscuits is obviously not as good as that of canned vegetables and fruits.

But he didn't expect the consequences to come to the fore so quickly.

"A severe deficiency of vitamin C can lead to scurvy." "The radiation dose on Mars is too high, and because of the lack of adequate atmospheric and magnetic field protection, it is full of high-energy charged particles from space and the sun, as well as secondary particles produced by the atmosphere and soil, mainly neutrons and γ rays - which do not exist on Earth." ”

"In a high-radiation environment, antioxidants such as vitamin C are depleted quickly in the human body at a much faster rate than on Earth." The old cat continued, "If you eat compressed biscuits on earth for three months, the symptoms will not be as severe as they are now, and I think if you continue to follow this trend, you will not be far from scurvy." ”

Tang Yue certainly knew what scurvy was, and in the seventeenth century, sailors on expeditions would suffer from scurvy due to a lack of vegetables and fruits, a disease that could cause joint pain, subcutaneous bleeding, and even death in severe cases. But in modern society, scurvy caused by a lack of vitamin C has been extinct, because this disease can be cured by eating more oranges.

But on Mars, where birds don't...... Finding an orange is as hard as finding an alien spaceship.

In a sense, the crew of the Orion spacecraft is in the same situation as the sailors of the Age of Discovery, except that the sailboat has become a spaceship, and the ocean has become space, but what has not changed is the difficulty of material supply, whether it is the sixteenth century hundreds of years ago, or the middle of the twenty-first century, when science and technology are highly developed, the shelf life of tomatoes and oranges will not exceed two months.

The scurvy, which had long been forgotten by people in the pile of historical papers, actually found Tang Yue 60 million kilometers away.

There are so many problems in people, Tang Yue thought that he would starve to death before.

Now that I think about it, this idea is purely redundant.

Before he starved to death, he could die of scurvy, kidney failure, heart rate disorders, and even some inexplicable allergies.

Tang Yue took out a white medicine bottle from the drawer and put it on the table.

"This is the last bottle of multivitamin tablets."

The old cat unscrewed the cap and glanced at it.

"With so many pills, how long will it take you?"

"It won't last long, no more than a month at most." Tang Yue replied, "If you eat more canned food and less biscuits in the next period of time, then the time can be a little longer...... But there is not much left of the canned food, and I will eat it again. ”

The old cat was a little worried.

A month later, Tang Yue ate all the vitamin tablets and canned fruits, then his vitamin intake would be greatly reduced, and all kinds of physical problems would follow.

These small problems, which can be completely ignored on the earth, will be magnified hundreds or thousands of times in the harsh environment of Mars, turning into insurmountable problems, and may even endanger Tang Yue's life.

The old cat was walking around the hall of Kunlun Station, and it had to find a way to replenish these nutrients that Tang Yue lacked in time.

"What to eat for vitamin C?"

"Oranges."

The old cat talks about oranges, but where can he find them on Mars? There are so many supplies in their hands, and the old cat can't conjure oranges out of thin air.

"Except for oranges?"

"Tomatoes."

The old cat sat down and frowned, "Tomato...... Tomato...... Where the hell are tomatoes in this place? ”

"Mr. Cat? Tang Yue? Mai Dong connected to the channel at this time, "What are you talking about?" I just heard tomatoes? ”

"We're looking for tomatoes." The old cat replied.

"Tomato?" The girl took a tomato in her hand, leaned in front of the camera and shook it, "There are tomatoes here, look at it." ”

"We're looking for tomatoes at Kunlun Station." The old cat said, "Tang Yue is now lacking in vitamin supplements, and he has to eat more oranges and tomatoes." ”

"There are no tomatoes in Kunlun Station, you can grow them." Mai Dong suggested.

The old cat and Tang Yue were stunned.

"Species?" Tang Yue asked, "Where will I grow tomatoes......

"It doesn't matter." The girl was ready to go, "I'll teach you!" Bao Jiao Bao Hui! ”
