Liu Yang is very strong, but she is a woman after all, and for many nights, she hid alone in the rest cabin and cried silently.

The plan for obtaining working fluid was decided, and it was also voted by all the crew, and Liu Yang became the technical guarantee of this plan.

She felt that her hands were no longer clean and stained with the blood of her companions, but on the other side she had to be strong.

The fate of mankind is in our own hands, and there is no choice.

So she made a thick cocoon to wrap herself, and became more and more emotionally cathartic, and everything she did was cold, like a humanoid machine.

It is only after finishing the day's work, when she writes the diary she left for her daughter, that Liu Yang opens her heart and gets some respite.

She writes about the progress of her research in her diary, as well as her vision for her life when she grows up, and even the future of mankind.

And Liu Yang will also record his cold side neatly at work.

Mei Zheren has always liked bitter before sweet, but when he browsed Liu Yang's work records, he still felt chills.

"On December 29, 2122, Da Liu left us today, but he merged with the Qinglong, and the process of refining the working fluid was smooth, and the expected efficiency was fully achieved, and the Qinglong increased the brake propellant by 1.6 times."

……

"On August 1, 2123, the activities of the Abaa people resumed, and today they reflected a medium-sized rocket and began to replenish the aging Starlink satellites, which is not good news."

……

"On October 1, 2123, National Day, I helped Lao Zhang and Xiao Luo to do an examination, Xiao Luo was in good condition, and Lao Zhang's condition deteriorated."

……

"On November 6, 2123, the spacecraft of the Abaren people was launched, Lao Zhang analyzed the orbital data, and felt that the comer was not good.

……

"On December 10, 2123, observing the preparation of the launch of the Abaa people's spacecraft, Lao Zhang formulated a counterattack plan, and Xiao Luo modified the jet, and I was in charge."

……

"On December 25, 2123, the Baa people's spaceship came, Lao Zhang's plan was successful, but he also left us, and this orbit change operation lost a lot of working fluid, but in order not to worry them, I didn't say, Xiao Luo has no talent for biochemistry, I hope he can cope with it."

……

"On December 28, 2123, Lao Zhang became part of the Hall engine as he wished, and he won Da Liu again, he added 1.7 times the power to change orbits, but the total amount dropped to 4.3 times."

……

"On March 8, 2124, the Ba people were beaten and feared, and they did not commit it again, Lao Zhang is right, he is more ruthless than the enemy, and today is a holiday, I conducted an accounting, and found that even if I add 1.3 times my times and Xiao Luo's 1.6 times, there is still a gap of two years."

……

"On June 1, 2124, Xiao Luo passed the assessment of biochemical extraction, and the electromagnetic snooping of the Baa people disappeared, and when the electromagnetic shielding cover was lowered, the intelligent robot could complete the scheduled operation, and the gap was still there."

……

"On September 1, 2124, when I saw the moon, I thought that if I accelerated along the tangent of the moon's orbit and calculated the timing of turning off the Hall thruster, I could use the gravitational tide of the moon's white to raise the orbit."

……

"On December 1, 2124, it took three months to regain the high number, and finally figured out the way to change the inclination and increase the height, which turned out to be the application of the Lagrangian theorem, and the orbit can be lifted once a month in the future, and there are six years to get back 1.2 times."

……

"On June 1, 2125, the lifting track went smoothly, but it's a pity that four years were wasted, otherwise there would be no gap, what should I do, I lost my hair again today, and my teeth are a little loose."

……

"On December 1, 2125, my hair fell out, and I lost 5 teeth, and I am at risk of osteoporosis."

……

"On June 1, 2126, half of the tooth was gone, I was sure that I had osteoporosis, Xiao Luo is in good condition, there is good news, there is a lot of carbon material in the computer, and we started to disassemble all the excess computing equipment."

……

"On August 1, 2126, the last 0.8 times was made up, I did it myself, I had enough food and clothing, I turned my teeth into ionized calcium, and the symptoms were relieved."

……

"On December 1, 2126, I felt that I should use the last year or two to do some constructive work and reopen the experimental catalogue and find specimens of tardigrades and mosses."

……

"On March 1, 2127, it was discovered that the tardigrades can absorb and transfer the moss genes, which may be the reason why the tardigrades can be dehydrated and reborn, but unfortunately there is too little time."

……

"On June 25, 2127, inspired by the tardigrades, I decided to abandon something that was not life-threatening and prolong my existence, intending to have surgery 5 days later with the assistance of Xiao Luo."

……

"On August 1, 2127, I amputated my leg and recovered, with an extra year and a half of ionized calcium and coenzymes, Xiao Luo's biology and physiology have made great progress, and there is no need to move on the space station, Xiao Luo helped me get a wheelchair, which was modified with an automatic robot."

……

"On June 15, 2128, gamma rays were used to successfully mutagate a gene chain of a tardigrade, and the photosynthesis of moss can appear on the body surface of the tardigrade, is it possible to reverse the radiation resistance of the tardigrade into the moss?"

……

"On December 1, 2128, seeing the light of day, the genes of the tardigrades have many translations from plants, and if successful, the cosmic moss that can photosynthesize and absorb energy will change the future of mankind."

……

"On May 1, 2129, four days later, another amputation was performed, and I wanted to throw away my excess burden and make myself young."

……

"On September 15, 2129, this time the recovery was very slow, I reached the limit, my daughter is almost 18, I don't know if she took the college entrance examination, I regret that I didn't learn math well that year, and the structure is always unreasonable when editing genes."

……

"On March 29, 2130, I have no spirit, I don't like to move, I'm about to become that 1.3 times, but after the amputation, I wasted some of it, Xiao Luo said it doesn't matter, and then dismantle a few chips, seeing Starlink, I really hope that when my daughter gets married, her wedding dress will be full of stars, and I hope that these nasty Starlinks above her head will disappear at that time."

……

"April 2, 2130, this is my last record, I survived yesterday, don't be a fool, I'm not a joke, my diamond will not be kept, there must be some chip backup, as a dowry for my daughter! Mother will definitely be the star that shines the most, and will always accompany and illuminate her daughter's life. ”

……

"On April 3, 2130, Sister Liu also left, and I didn't follow Sister Liu's orders, so I left her behind, and she continued her unfinished experiments in the photosynthesis light of the feeding tank."

Mei Zheren finished reading Liu Yang's work diary and contacted Li Hengwang at the Xiyuan base.

"Can you find Liu Yang's family and daughter? What about the families of the other astronauts? ”

Li Hengwang hesitated for a moment before replying: "Liu Yang's lover is a fighter pilot......

The rest Li Hengwang didn't say anything, Mei Zheren had fully understood, and he let go of the question.

Li Hengwang made up the answer by himself: "Liu Yang's daughter is still in the base, inherited her mother's volunteer, engaged in biology and physiology research, and now has graduated with a doctorate and joined the Academy of Sciences. ”

Mei Zheren asked another irrelevant question: "Has the baby got married?" ”

"Not yet, I don't even have friends, I'm always not in a hurry."

"Oh, you know each other well?"

Li Hengwang was a little ashamed: "Later, she followed me and my lover to live, and we treated her as a daughter." ”

Mei Zheren nodded: "Two things, in the future, I will take her research group to try to complete the project on photosynthesis left by her mother, and I will be her grandfather when she gets married." ”

Li Hengwang immediately excused: "No, no, no, you can't mess up your generation." ”

"It's none of your business, what? Think you're taking advantage of me? ”

"That's not true, her father is also surnamed Li, and he is my cousin."

"What does it matter?"

Li Hengwang squeaked for a while and popped out a sentence: "You were originally the child's aunt, and the child's grandfather is Li Dada." ”

No wonder Wang Xuezu was sent to Xiyuan and Li Chengcai didn't say a word.

Li Dada can, it's all mixed in the aerospace system.

Mei Zheren suddenly remembered that Ruyi was cultivated back then, and the military sent a drone, which Mei Bigu disliked, and later seemed to be cheaper Li Dada.

Could it be that the drone has pitted Li Dada for the rest of his life?

The younger generations of the old Li family, the male followed Li Dada to engage in aerospace, and the female followed Li Xiaoxiao to study biology, which has become the origin of family learning.

Mei Zheren replied to Li Hengwang with a "I know" and didn't answer him again, now he is a grandchild and has no human rights.

Li Mengxing, who was far away at the Xiyuan base, didn't know that her happiness compensation package fell from the sky.

Since he is his own junior, Mei Zheren is not polite, he opened the diary written by Liu Yang to Li Mengxing and browsed it.

He has to know what Liu Yang's wish is, so that he can help her realize it, isn't the old man just a responsive function!

"Mengxing, mom hopes that you will also be like mom in the future, it can help us find the mystery of life, the continuation of life, women understand it most thoroughly."

"Daughter, my mother thinks that whether it is biology or medicine, ignoring mathematics is still a big shortcoming, and the number of biology and medicine is not enough, my mother just learned that our favorite moon white has such a great impact on us humans, and the effect of moon white gravity on human beings is far from clear, I hope you can one day unveil the veil of moon white mist."

"Do you remember what your mother told you about the tenacious tardigrades? Mom discovers that the tardigrades are closely related to mosses, and if you solve them, you can get a glimpse of the mystery of the tardigrades' immortality. ”

"Girls should be brave and strong like tardigrades to face their own lives, your mother is not by your side, you must practice the skills of tardigrades to adapt to various environments, so that you can face all kinds of challenges, daughters are as soft as water and as strong as water, good at water."

"Today, my mother completed the implantation of photosynthesis on the body surface of the tardigrades, and then I found that if the plants have the survivability and anti-radiation characteristics of the tardigrades, then the energy regeneration and utilization of human beings will reach a new level, and I hope that in the future, as long as there is sunlight, there will be endless marshmallows."

"Mengxing, do you dream of your mother? Mommy dreams of you again. Now Mom is picking stars for Dream Star, Mom wants to pick off the stars in the sky and embellish them on your wedding dress, Dream Star will definitely be the most beautiful bride in the world, if Mom is not there then, please look up at the starry sky, Mom will be the brightest one, always watching you in the sky. ”

Mei Zheren turned on the lighting array of the photosynthesis laboratory, took out a diamond from the lampshade, and gently placed it in Liu Yang's military merit medal box.

"Child, grandpa will take you home to watch Mengxing's wedding, and grandpa will ensure that Mengxing's wedding dress is brighter than the entire starry sky."
