I couldn't see it when I was a child.

Now that Su Beidou is more than five years old, there are already some signs of something bad.

Compared to his peers living on Earth, he is a lot taller, and the average boy between the ages of eight and ten is about the same height as him, which is not a good thing.

Lack of muscle mass, weight loss, and rapid rise in height led to unbearable leg pain at night, and countless nights in the past two years were awakened by pain.

There are many growth marks at the base of the thighs and leg joints, which are the marks left by the skin fibers being pulled off.

Calcium and vitamin supplementation alone can only play a relieving role, in the final analysis, it is because the gravity of Mars is weak, so the growth rhythm is accelerated by external forces, even if the Su family is rich, it cannot change these physiological troubles.

Fortunately, his appearance is not disabled, he has a yellow face like his parents, his skin is fair, his facial features are gradually obvious, he has the potential to become a handsome little guy, his hair is slightly long, and he has always touched his shoulders.

There is no way, there are biological experts, mechanical experts, medical experts, geology and mineralogy experts in the base, etc., but no one has the skill of haircuts, and like his mother Zhao Xin, Su Beidou's hair is also a little naturally curly, and it looks pretty good.

The heartbeat rhythm is weaker than that of normal people, similar to the muscles of other parts, and the heart tissue muscles are enough to reach this strength on Mars, but if you return to Earth, it is likely that you will directly stop and start the countdown to death belonging to Su Beidou.

No one takes the time to exercise, so at this age they start push-ups, leg raises, and jump rope almost every day.

The adults at the base thought that this little guy who was no longer so small was just idle and bored looking for something to do, and no one guessed that Su Beidou was just trying to save his life.

He wanted to live and return to Earth alive, so he began to deliberately increase his physical strength from the time he first knew how to walk and learned that he might die unexpectedly at any time, although he didn't know what was enough, at least it was better than lying down all day waiting to die.

It's pitiful.

Since he was born, for more than five years, Su Beidou has never left the base for half a step, in the eyes of others, even in the eyes of his parents, he is a porcelain doll.

Those mercy are hidden in the eyes, so almost everyone who comes to Mars shows special friendliness to him.

Su Beidou's birth once shocked the world, and now his parents don't even dare to teach him much, and rarely mention the situation on Earth.

As for the reason, it is probably because I am afraid that the greater the hope, the greater the disappointment.

If it were possible, the couple who had been on Mars for six years for their son would naturally bring him back, but if there was no hope, they would rather Su Beidou live like this forever, even if they could never set foot on Earth......

Knowing that Su Beidou never told anyone about his guesses, he just silently spent seemingly invaluable time, trying to make his body stronger.

Usually acting like a taciturn child, in fact, the way of thinking is similar to that of an adult, which is very abnormal, because I don't want to talk about it to anyone, hiding this little secret from my parents, and the fear of death in my heart.

Living in a narrow and sealed environment, after a long time, it is inevitable that you will encounter some psychological trouble.

*******

A needle is poked into a blood vessel to draw out a small amount of blood.

Since he was born, blood has been drawn every two weeks, and the pinhole from the last time can still be seen, and a new pinhole has appeared.

Lao Chen, Chen Dafeng, a few years later, he still stayed on Mars, still the same, growing vegetables all day long, feeding those increasingly strange animals, staying in the laboratory to do some research, he is one of the people Su Beidou is most familiar with since he was born.

Sometimes, Su Beidou felt that in Chen Dafeng's eyes, he was also a guinea pig that could be used for research, but he couldn't produce evidence.

It's no wonder that he thinks about it too much, it's really that every time he takes blood and does a physical test, this guy's eyes are too bright.

It's right to think about it, since he was still an embryo, Su Beidou has been living on Mars, which can be called a unique research ontology in the whole solar system.

Chen Dafeng, as a scientific madman, has been on Mars for more than ten years in order to research, how could he let go of such an excellent research object as him, and every time he personally handles it, Su Beidou has lost count of how many times he has been drawn blood.

Then the weight was measured, blood pressure and heartbeat were recorded, grip strength, bounce strength and so on were tested, and a whole set of fixed procedures was walked down, and nearly an hour passed.

The data was entered into the computer, and after so long, Su Beidou had already learned to read the data by himself.

Except for the height is particularly prominent, the other data is still lower than the average level of children on the earth, and in terms of muscle strength, it is only about 60% of the strength, which is still the result of exercise.

To put it simply, if he fights, he may not be able to beat a five- or six-year-old weak chicken on the earth, and a teenager can break a few ribs with a single kick.

Mars is about half the diameter of the Earth, about one-ninth of the mass of the Earth, and the gravity is about 38 percent of the Earth.

"It's not bad, keep exercising. Take off the water bag, I fill it with more water, run more when I have nothing to do, and keep my squats up to make my heart move. ”

Lao Chen said with a smile on his face, most likely because he wanted to be lazy, and then added: "Come to me to help when you have time, the potatoes are about to ripen again, I taught you how to dig potatoes, sweet potatoes can almost be eaten, dig them out and I'll help you bake them." ”

Nodding, like being kept in a cage, it's always good to have something to do.

Su Beidou then asked: "When can I go out?" It doesn't take too far, just walk around, and I will definitely come back before the oxygen runs out." ”

"I guess it's not okay, your grandfather designed a small spacesuit for you, but it's too heavy, and you'll have to come back after walking a few steps out of the door." ”

Seeing Su Beidou sighing, Lao Chen was afraid that he would be sad, and after thinking about it seriously, he said again: "But you can stay in the car, as long as you don't mess with the buttons, wait for your dad to come back next time, and let him take you around when the time comes, I think it should be fine, but you can't get out of the car." ”

When a normal person wears a spacesuit for going out, it feels like carrying a rather heavy schoolbag on Earth, just right.

And he is already weak, and he will definitely not be able to bear it after adding the weight of the spacesuit, Lao Chen feels that this child has grown up in the base since he was a child, and it is really cruel not to be able to go out to see, so he is willing to do a small favor, and is ready to talk to Su Beidou's parents about this matter when the time comes.

It's already good news, Su Beidou was impatient, and urged: "Don't wait for my dad to come back, isn't Uncle Song's team there, and the car is there, I can go out now!"

“…… Alright then, you wait a minute, the people at Bald Eagle Base have destroyed the vegetable garden, come to us in the afternoon to buy food, and I'll help you ask when they're gone. ”

Lao Chen couldn't help but laugh when he said this, because he thought that this was the first time in more than ten years since he landed on Mars that there had been trade between bases.

Su Beidou is ruthless enough, just ten tons of food, and he actually asked for 40 billion Hong Kong dollars, and a ton of potatoes is 4 billion Hong Kong dollars, which is simply a money grab.

In the end, the other party actually agreed, there was no way, only this God of War base had a lot of food reserves, otherwise the people over there would all starve to death if they couldn't last two months.

After thinking about it, Lao Chen felt that there should be more potatoes in the near future, and it was still far from the landing window, since the Bald Eagle Base could not grow food on a large scale, it was estimated that he would have to buy it again......
