Mr. Qian was very touched by Qian Xiaolan's concern. He laughed and comforted Qian Xiaolan:
"Don't worry, girl. Your grandpa is still young. It won't be a problem for me to beat 20 or 30 people.
If they come, grandpa will play with them to their heart's content, and grandpa promises that they will never get hurt."
As he spoke, he subconsciously reached out and touched his chest.
Not to mention, if it weren’t for his good granddaughter letting him wear this precious thing, he would have died long ago.
Qian Xiaolan didn't know that the old man was shot in the chest today, but she knew why her grandfather did that.
Because her father and many researchers have spent a lot of effort, the deep-water submarine independently developed and designed has been completed and is about to be launched for the first time.
The initial funding for the development of this submarine was very tight. Later, the two uncles not only provided a large amount of financial assistance to the country themselves, but also attracted a group of Hong Kong businessmen to make various investments in the mainland.
Afterwards, the country used all the funds to build submarines.
Even so, it's still a long way off.
Therefore, in addition to quietly providing technical assistance to her father, Qian Xiaolan also secretly donated many of the treasures in the space to the country.
The country auctioned off batch after batch of less important items and invested all the funds in it.
Finally, the submarine was successfully built.
The nuclear submarines that entered service in the past few years can be said to be the best technology of the time.
However, the "Deep Sea Shark" submarine developed by Qian Jingming not only made major technological breakthroughs.
Many previous deficiencies have also been improved.
The most amazing thing is the pressure resistance of the submarine hull. The previous ones could only dive to a depth of 300 meters, but this submarine can reach more than 5,000 meters.
What a huge change this is?
Every time the academicians of the Academy of Engineering watched this, they felt both gratified and regretful.
In order to manufacture the submarine hull, they opened a new assembly line and made it according to the precise values provided by Qian Jingming. They failed countless times before they succeeded.
If this technology had been available a few years earlier, that nuclear submarine would definitely be able to surpass Country America and Country Y!
But on second thought, it’s not too late now!
Everyone suddenly smiled with joy.
The country attaches great importance to this "deep sea shark" and no one dares to think of any mistake.
On the day of launching, the old men in Kyoto will definitely come to witness this historic moment.
Qian Xiaolan knew that her grandfather wanted to use him to attract the attention of those countries.
She knew about this because she was now considered half an insider.
The reason why I say half is because she was not invited to the secret base.
Since she had to take care of the children at all times, she was allowed to conduct some small experiments in the staff dormitory.
Gu Yanqing was recalled on the day when Guoguo's baby was one month old, and now he is running between the army and the secret base.
However, due to his current talent in modifying guns, he no longer takes long-term missions, and at most only does peripheral missions.
The scientific researchers in the secret base all valued talent and advised Gu Yanqing many times to concentrate on his research and not take any risks.
But Gu Yanqing had his own ideas. He felt that with his current skills and the advanced bulletproof vest given by Qian Xiaolan, it would be a waste and too boring to just do research.
He was not a man who could sit there quietly.
He likes challenges and the feeling of defeating his enemies.
So it becomes a brick and can be moved wherever it is needed.
Qian Xiaolan thought that Gu Yanqing would also stay by her grandfather's side to protect him, so she stopped worrying about him.
This time she got a special plant from the original plane. Ah Hu said that people there eat it as a vegetable.
Testing has shown that this plant contains particularly high levels of selenium.
She wondered whether plants could be widely planted in this world.
If you can, it would be a great merit.
Selenium is a multifunctional nutrient that is often used to treat more than 40 diseases, including Keshan disease, Kashin-Beck disease, cardiovascular disease, diabetes, liver disease, prostate disease, heart disease, cancer, etc.
Widely used in cancer, surgery, radiotherapy and chemotherapy, etc.
There are more than 40 countries and regions in the world that are selenium-deficient.
The Great Xia Kingdom even has an entire low-selenium zone that occupies 72% of its land area.
Among them, 30% are areas with serious selenium deficiency. The selenium content in natural foods such as grains is very low, and it is difficult for people to supplement selenium from food.
Selenium deficiency is also an important cause of Keshan disease and is also considered to be an important cause of large bone diseases.
Kaschin-Beck disease mainly occurs in adolescents, seriously affecting bone development and future working and living ability.
Young people are the hope of the country's future. If she can promote this plant, people will be healthier and the country will get better and better!
Qian Xiaolan did it as soon as she thought of it. After Guoguo and her grandmother went to bed, she went into the space.
First, she contacted Ah Hu and asked him to dig up some soil from around the plant. She would analyze the composition and then see if she could grow it in her own yard.
Ah Hu didn't know what Qian Xiaolan was going to do, but he was always an obedient man. Whenever Qian Xiaolan asked him to dig, he would dig it without asking any more questions.
Qian Xiaolan never cheated him and always gave him enough food.
This is enough for Ah Hu and the people in the tribe.
Ah Hu was still very efficient this time. Within half an hour after Qian Xiaolan's message was passed on, he had already put up a bamboo basket of soil and two baskets of the plants.
Erect herb, leaf-like branches clustered in 3-6 pieces, smooth stems, young stems edible.
