Although it is almost a generally accepted basic criterion, the higher the purity of the base material, the fewer impurities and the more outstanding its properties. Even for alloy materials, the purity of the raw materials is a very important indicator when developing the material formulation. However, it is precisely because there is never a material in the world that does not have a trace of impurities, so the purification of materials will become a profession.

Purification is easier said than done. There are chemical, physical, biological, and thermodynamic principles and a whole bunch of formulas at work. Therefore, all the industrial powers in the world have spent a lot of manpower and material resources on this. There is no big trick to this basic subject, only time and hard work can be summed up, and maybe a little luck.

China set off too late, and the foundation is very insufficient. Coupled with the particularity of ideology, Western countries can be said to be strictly guarding against China's technological progress. In this kind of subject that purely relies on accumulation, the current achievements are already miracles created by the patriotic enthusiasm of Chinese scientific and technological workers. If it weren't for Shen Yiyi's usable "god man" against the sky, she really wouldn't dare to dream of any breakthrough in this matter.

And now, with Xiaobao, a real "little genius", Shen Yiyi can't help but want to try his golden finger.

Seeing that Xiaobao agreed to his proposal, he only needed to go back and ask the research team to prepare a few plans to determine the direction of work and abstract them into mathematical models, Shen Yiyi was also very relaxed. She and Zhu Bowen chatted with each other, and by the way, after walking all the roads that people of her level could walk, they began to walk back.

Zhu Bowen is the only one he can rely on in this environment, and he can be regarded as a familiar big sister, so what Shen Yiyi said has a considerable soothing effect on him. What's more, Shen Yiyi alternates Cantonese and Mandarin from time to time, and even uses some English words according to the habits of Hong Kong people, these intentional actions make Xiaobao feel at ease on the first night after leaving his hometown.

When I get back to my grandfather's compound. Shen Yiyi directly asked Xiaobao to go back to his bedroom first to get ready. As soon as Xiaobao came home, her grandmother had already asked Shen Chong to vacate the room where they had stayed when they were children, and used it as Xiaobao's dormitory during his time in Beijing. So speaking of which, Zhu Bowen's children will have their own foothold in Da Nei from today. Of course, in the blink of an eye between words, in fact, there must be an old man and an old lady's staff running around behind it. Find someone to stamp it. This is not an ordinary residential area, and the security level here is very high. If you want to live in, it is inevitable to have a political trial or something. This is that Old Man Shen used his old face to vouch for Zhu Bowen, otherwise he would have to be blocked out of the country by virtue of his identity as a Hong Kong compatriot.

Shen Yiyi walked in front of his mother and grandparents one by one, found a stool and sat down. Everyone else in the family left, so his mother stayed behind to accompany her in-laws, and it seemed that she was going to interrogate herself three times.

Shen Yiyi just wanted to say something, but the old man Shen Haijiang opened Chrysostom first.

"Xiaobao's school has already been arranged below, so let's put it in No. 4 Middle School." Shen Haijiang said unhurriedly. That's the beauty of power. Beijing No. 4 Middle School is a school that ordinary people can get into, but the old man said a word. Students like Xiaobao can go in and study. If ordinary Beijing citizens knew about this, they would definitely be jealous and envious of a few words about "using power for personal gain" or something.

Shen Yiyi didn't think that Beijing No. 4 Middle School was so remarkable. From her previous life to this life, every school she wanted to go to was not bad, and she was admitted by herself...... Maybe we have to subtract the time when Comrade Shen Jianguo used his own family members of the army to get Shen Yiyi to Shenyang No. 11 Middle School.

But even that time, in the end, Shen Yiyi relied on his own ability to go to Tsinghua University after only one year. Whether this is more than Shen Yiyi from the eleventh, or more than Shen Yiyi brought to the eleventh, it's really hard to say.

So, although there is a request from Zhu Eva to help her watch the children and take care of the children almost in exchange. Shen Yiyi really didn't feel anything special about Beijing No. 4 Middle School. Schooling is only one aspect, and the more important education is often done outside of school. For example, at the homes of classmates.

She believes that with Xiaobao's small head, and the fact that she will live with him from time to time in the future, she believes that Xiaobao has no problem with learning under her nose. So for her grandfather's explanation, she just said "oh" lightly.

Yang Rui looked at her daughter's expression that she didn't take to heart, and glanced at her in-laws with some apprehension. She knew the status of this four. If it weren't for his own daughter's struggle. Now she is among the top spears in the prestigious schools, otherwise she would have to sigh why her daughter has not enjoyed this kind of prestigious school treatment when she hears it.

She was a little afraid that Shen Yiyi's indifference would make her in-laws feel that this little granddaughter didn't know what to do, and then blame her for being a mother. But on the other hand, the old man and the old lady are very accustomed to Shen Yiyi's cold expression. This was a bit unaccustomed to her, who had never lived with her in-laws in the first place.

The grandmother of the Shen family didn't bother to talk about these other things. She doesn't care about Xiaobao's schooling. Of course, the old lady would take care of the little child brought back by her little granddaughter, but she was more interested in asking about the roses.

"One by one. What about the flowers you got back? Why don't you take it out and find a vase to plug it in? ”

The old lady looked very interested in helping her little granddaughter arrange flowers, and she was very enthusiastic.

Yang Rui muttered in her heart: "Old lady, what are you doing?" Are you encouraging this child to fall in love now? ”

However, her daughter-in-law, who has only been in the house for more than two years, is still not familiar with the two old men, so she can only put any thoughts in her heart and dare not say them directly.

Shen Yiyi has been with her grandparents for a long time, and she already knows each other's tempers quite well, plus she knows in her heart how the second elder is pampering herself, so she can show her personality without any scruples in front of the two old men, of course, she will also pay attention to the proportions.

"That bouquet of flowers, I threw it on the windowsill." Shen Yiyi said casually.

"On the windowsill?" The old lady cried out, as if something undesirable had happened, "Yiyi, this is the first time someone has given you roses, you should put them in a vase, put them on the table, and smell them every day." How can you just throw it aside? ”

Shen Yiyi looked at his grandmother's look like this, and felt as if it was grandma, her old man was even more energetic than herself.

Maybe it was because Shen Yiyi's eyes looked at the old lady that the old man also felt that his wife was too active today, and Shen Haijiang couldn't help coughing and reminded his wife not to go too far.

Grandma Shen also realized that she seemed to have substituted herself into the identity of her little granddaughter, and those feelings just now brought her back to the good times of her youth, imagining what her mood would be like after a young man who liked her confessed to herself with a bouquet of flowers.

At this time, Shen's mother Yang Rui interjected. She also saw that her mother-in-law was a little embarrassed, and in order to relieve the encirclement, she, the daughter-in-law of others, took the initiative to take over the conversation.

"One by one, there are no outsiders here anyway. In front of your grandparents and mother, you sue us, is the bouquet of flowers you received today a gift from Wang Kai? In what name did he send the flowers? Have you ever ...... with him?"

Shen Yiyi looked at his mother and asked himself with a stern and serious look, just like the director of education in the school. She replied to her mother in the same strict manner: "That's good, I'll officially tell you, that's right, this is the flower that Wang Kai gave me." In what name, it's a birthday present to wish me a happy birthday. If you want to ask me about the relationship between me and him, it is a good friend and a business partner. That's it, nothing else. ”

The mother and daughter's questions and answers made the atmosphere a little tense, but they finally figured out what everyone wanted to understand.

Or Shen Haijiang nodded: "The operation of the company that that the Wang family kid has been doing with you during this time is not bad, right?" I heard your uncle say that your garment factory has become bigger and bigger, and that the sales volume in half a year has exceeded 60 million, so won't it be more than 100 million this year? It seems that that kid from the Wang family really has some ability, and he is better than those guys who can only take the approval and pour it around. ”

Shen Yiyi saw that his grandfather had diverted the topic, and knew that at least the grandfather of the second elder did not want to ask about this issue. Knowing that he already had at least one ally, Shen Yiyi replied cooperatively: "I didn't expect my uncle to care so much about my company." That's right, I asked Wang Kai to report this number. This year, we want to report the national famous brand, and then rush to the seat of the All-China Federation of Industry and Commerce, so there are some quantitative requirements for sales indicators to meet. ”

Shen Haijiang nodded: "Being able to bring a small factory to such a big one, you can be regarded as fighting for our Shen family." And I'm even happier that you have invested all the money you earn in the country's scientific and technological progress. This spirit of benefiting the country and the people is what Lao Wang and I value the most. (To be continued......)
