Whether it is a new type of battery or a composite material, it can make Chengyuan's science and technology crystallization company make a lot of money in the cooperation with the above.

Compared with the former, Cheng Yuan prefers composite materials. After all, the latter is more widely developed and is also more useful than batteries in the field of application. Moreover, Cheng Yuan's future scientific and technological inventions also need to cooperate with the developed industrial base.

"Zero, extract the graphene composite steel metal material within the matrix. ”

This composite steel is made of fine tubular graphene that is fused into ordinary alloy steel at high temperatures to form a honeycomb structure with the same stability as diamond. The strength of this new composite gold material is 500 times higher than that of alloy steel of the same weight! And it also has strong resistance to compression, friction, high temperature corrosion and so on.

The emergence of this composite metal may make all military enterprises in China have a big change of equipment, but Cheng Yuan believes that the country will not hesitate to invest a lot of money in it after verifying the performance of composite materials.

Because of the losses suffered by industrial backwardness, people who pay attention to this aspect must have a deep understanding, as long as there is hope, they will not hesitate to put everything they can put into it!

After extracting and printing the data, Cheng Yuan carefully put it away.

Compared with the preparation technology of graphene, this composite material is the big head.

Since graphene was studied, countries around the world have been developing this material, trying to integrate it with various materials and enhance the properties of other materials through graphene.

Although the preparation technology in Cheng Yuan's hands can produce high-quality multi-type graphene in large quantities, this only reduces the existing sky-high price of graphene, and allows researchers to conduct experiments more extensively.

Time always passes inadvertently, and when Cheng Yuan comes back to his senses, he finds that the sky outside has completely darkened. Coming out of the office, he found that the company's employees were still busy, Cheng Yuan's heart moved slightly, took out his mobile phone and looked at the time, today is the 23rd, that is to say, in three days, it will be the day of Dabai's global release.

Cheng Yuan's spirit was shocked, and he was a little excited in his heart.

The early sale of Dabai has already brought them unparalleled popularity around the world, and he can imagine what a hot situation will be when the global release is going to be this time.

At the beginning, nearly 10,000 units brought him billions of profits, although the price of synchronous sales was not as high as when he snapped up, but his base was even larger, Cheng Yuan couldn't believe what kind of huge wealth he would bring to himself on the first day of synchronous sales!

Holding back the excitement in his heart, Cheng Yuan did not disturb the work of the employees and quietly left the company.

When he returned home, Cheng Yuan just opened the door, but unexpectedly found that in addition to his parents and little sister, there were two more middle-aged couples in the house, as well as two young women and a young man in his early twenties, a total of seven people.

Both parents and little sister were sitting on the sofa, but the father looked embarrassed at this time, saw Cheng Yuan coming back, smiled at him, and then lowered his head and smoked a puff.

Seeing his father's movements, Cheng's mother glared at him unhappily, then got up and came to Cheng Yuan, and said to Cheng Yuan with some complaints: "Xiaoyuan, why did you come back so early today, and you didn't make a phone call in advance, and you haven't cooked any meals now." ”

The mother's voice was very loud, but the meaning contained in the words made the faces of the men and women change slightly, but they quickly adjusted their mentality, as if nothing had happened, looked at Cheng Yuan with a kind smile on their faces, and nodded.

Cheng Yuan glanced at those people lightly, then smiled and said to his mother: "The company's affairs are not busy today, so I came back early." ”

"By the way, who are they?" Cheng Yuan whispered in his mother's ear.

These people who came to the house were dressed quite classily, and they were not ordinary people at first glance. But this is also where Cheng Yuan is puzzled, their family seems to have never had anything to do with such a family. So he's curious about these guys.

Hearing Cheng Yuan's inquiry, Cheng's mother snorted lightly and said in a low voice: "They are your father's own brothers!"

"Really!?" Cheng Yuan was suddenly startled, and looked at the people in disbelief.

What kind of rhythm is this, he has never heard of any relatives in his family since he was a child, and since he can remember, every New Year is spent with their family and Guo Xiaolian's family.

Whether it is father or mother, neither of them seems to have taken him and his sister to visit relatives during the New Year!

Cheng Yuan's startled action made Cheng's mother poke Cheng Yuan's chest with her finger angrily, and said angrily: "Naturally it's true, is it still fake?"

Cheng Mu said, as if she remembered something, her eyes turned red, and she pursed her lips and walked quickly towards the inner room.

Cheng Yuan saw that his mother's eyes were red, and his heart suddenly became angry, from his mother's actions at this time, he guessed that these so-called 'relatives' must have done something to make his mother sad before.

What did he study hard for since he was a child?

It's not for the whole family to live a good life, parents don't have to worry about those trivial things every day, and they don't have to be anxious about the tuition fees of the brothers and sisters!

When he was a child, he couldn't make money and could only comfort his parents with transcripts and awards, and when he saw his parents holding the transcripts in his hands with a happy face, he felt that all his efforts were worth it!

But now, his initial goal has been achieved, as soon as these so-called 'relatives' come, it makes the mother feel uncomfortable, as a filial son, can he not be angry, can he not be angry?

However, when he thought that they were his father's own brothers, he couldn't scold them without saying anything, and if this matter got out, whether it was right or wrong, his reputation would definitely be damaged.

After Zheng Jia's 'indirect' cultivation for several months, Cheng Yuan also understood a lot of things.

glared at a few people coldly, Cheng Yuan didn't say a word, and walked directly towards the inner room. These relatives who had never seen each other suddenly came, and Cheng Yuan knew with his toes that it must have something to do with his company.

Fortunately, he just wanted to make his parents' life easy in the future, not to be worried about those trivial things, all the company's things he never mentioned at home, after all, the company's in and out of hundreds of millions of funds, such a large amount of him was afraid that after letting his parents know, there would be more pressure in his heart.

Therefore, as long as he does not let go, even if his father agrees to anything, it is useless.

When her sister Cheng Xin saw that her mother and brother's expressions were wrong, she quickly got up from the sofa and ran after her. Although she was still young, she also knew that her mother and brother didn't seem to like these people very well.

Cheng Yuan and the three left, and the atmosphere in the living room suddenly became awkward.

"This kid, the misunderstanding of us is quite deep, the third child, you have to help us explain. Opposite Cheng's father, a middle-aged man who looked more than ten years younger than him smiled awkwardly and broke the silence.

Beside him, the noblely dressed woman also accosted her, with a gentle smile on her face, and said softly: "Yes, we are all a family, who can be closer to you than us?"

As soon as the two spoke, the rest of the people chimed in.

"The third brother, it's not that the second brother said you, it's not that the family doesn't enter the door, you have to talk to Xiaoyuan well, we are here to help. ”

Another middle-aged man who looked younger said: "You see that it is not easy for Xiaoyuan to support such a large company by himself, and the two of you can't help, and Xiaoxin is young." This company relies on outsiders to help, who knows if those people will swallow your family's money. ”

"Don't say anything else, our Xiaopeng is an accountant, let him help your family Xiaoyuan manage the accounts, and he is not afraid of outsiders making fake accounts or something, isn't it?" The man patted the shoulder of the young man next to him and said earnestly.

"And your two nieces, they are both graduates of prestigious universities, and they have absolutely nothing to say in management. ”

Father Cheng raised his head and glanced at a few people complicatedly, and said in a muffled voice: "It's useless for you to tell me about this, Xiaoyuan has his own ideas, I can't control it, and I don't want to care about it." After a pause, he said again: "His mother is not feeling well, I'll go and see, you guys go first, I'll mention this matter to the child." ”

Cheng's father's words made several people pause, and they looked at him fixedly for a long time, and the middle-aged man who spoke first sighed and said, "Okay, think about it, the brothers are here to help you, don't think about him too much." After speaking, he took people to leave Cheng Yuan's house.

Father Cheng watched them leave silently, the sadness on his face was even worse, and he sat on the sofa for a long time, and finally turned into a long sigh.
