Winter break is coming soon, and the final exams are coming as scheduled.

When the last final exam was over, Yunmiao and his friends began to prepare for the holiday.

The music school where Shuiyin works is also on winter vacation, but Shuiyin is busier than ever. She has to go to her teacher's home every day to receive dual guidance from Li Suyun and Xu Yanqing.

The coming of winter vacation also means that Yunmiao begins to let herself go without the daily supervision of her mother.

Yunmiao sometimes rehearsed with her teammates, and sometimes she and her sister went to Xu Yanqing's home with her mother to see her mother's "learning" progress. She lived a happy life.

On New Year's Eve, Shuiyin and her two children canceled all activities and started cleaning their already clean home.

Yunmiao and her grandfather posted couplets and hung lanterns together. It was a peaceful and joyful scene celebrating the New Year.

At noon, Shui Yanfeng, who had been hiding in the laboratory for a long time, also drove back to Yun's house.

The two old people were watching TV, chatting, and drinking tea in the living room. Shuiyin and Yunmiao's grandma were busy in the kitchen with the New Year's Eve dinner.

Yaya would run into the kitchen from time to time and ask for delicious food from her mother or grandma.

Yaya smiles like a flower every time she enters the kitchen. When she comes out, her little mouth is oily and her eyes are like crescent moons. Today is the happiest time of the year. Judging from her appearance, she probably doesn’t even need to eat dinner.

.

After Yun Miao took the time to ask her grandfather about the progress of the experiment, Yun Miao's little mind began to come alive.

He returned to his study quietly, then took out his cell phone and called Xie Yiyi.

"Sister Yiyi, how is the development of mobile phones now? To what extent?"

"I also want to tell you that the professor and his students are making rapid progress. The music ring tones you mentioned are currently being tested, and they will all be tested in another month. However, the only drawback is

It just consumes a lot of power and the standby time is too short.”

Hearing Xie Yiyi's answer, Yun Miao wanted to laugh out loud.

"As expected, God helped me. Today is a double blessing."

Xie Yiyi didn't understand and didn't know what Yun Miao was talking about.

"Sister Yiyi, the time for our revenge has come. You have to be prepared, when the time comes we will kill him until the sky is dark."

Yun Miao was in a good mood. The depression in her heart could finally dissipate.

"Wait a moment."

Xie Yiyi returned to her bedroom, closed the door, and then asked: "Yunmiao, are we sure now?"

"Sister Yiyi, you can celebrate the New Year with peace of mind. After the New Year, you can investigate the competitors named Xu. The so-called enemies of enemies are friends. We can definitely join forces with the enemies of our enemies. I have the patent for a new type of energy-saving battery in my hand. I think they must

If they are interested, we can also ask them to help us make batteries for mobile phones, making money and taking revenge without delay."

After hearing Yun Miao's explanation, I knew that Yun Miao already had a trump card in his hand.

"Okay, I understand, I will arrange for someone to do it."

After hanging up the phone, Yun Miao thought about it, picked up the coat on the bed, and walked out of the study. Going downstairs and coming to the living room, Yun Miao saw his grandfather and grandpa playing chess, so Yun Miao came over.

"You want to go out?"

Old Man Yun looked at his grandson holding his coat, indicating that he was about to go out. He asked in confusion.

Where are you going on New Year's Eve? Who is not busy with New Year's Eve dinner at this time? Is there anything to see?

Yun Miao glanced at the kitchen

direction, and then sat on the sofa nearby and said: "Grandpa, the new project studied by grandpa has made great progress and can basically be put into production for civilian use. I originally wanted to give Li Wenhe their real estate project as compensation, but

, now that grandpa’s project is successful, I want to give a small part of it to them.”

The two old men put down the chess pieces in their hands and looked at Yun Miao curiously.

"Grandpa, grandpa, my industrial line cannot be too long. I can only seize a few core industries in the future. Although grandpa's new research project is also the core of the future, it does not match my strategic deployment. Although

We can also make money, but I can't hold all the money-making industries in my hands. This is also not conducive to the management of the company. Instead of doing this, it is better to take it out and let our allies participate. While we fulfill our commitments, we can also let

They share risks for us and can even protect us from wind and rain. We can’t make enough money.”

Old Yun took a sip of tea, looked at Yun Miao, and then at his in-laws.

"Can your scientific research results really be put into production?"

Old Man Yun asked curiously.

Shui Yanfeng nodded, "Basically, it's possible, but it's only limited to civilian batteries. Others are not yet available, and it will take some time and continued investment in research."

Old Man Yun nodded. In the battery industry, there are many manufacturers in the country and the uses are relatively wide. However, the gap in economic benefits and the competitiveness of peers is also relatively large. Therefore, he is not optimistic about the allies mentioned by Yun Miao.

, acceptable.

Seeing his grandfather's expression, Yun Miao knew that his grandfather was not optimistic about this industry. Then Yun Miao began to explain: "Grandpa, I will plan the industrial layout and future market strategy for them. This is a rising industry.

, there is a lot of potential for the future.”

"Oh, tell me."

Old Man Yun had an expression that said, "Don't fool me."

"Grandpa, batteries are widely used in UPS, electric vehicles, scooters, automobiles, wind energy and solar energy systems, security alarms, etc. It is called the new energy industry."

Before Yun Miao could continue, Old Yun interrupted Yun Miao.

"Wait a minute. Electric car?"

Yun Miao nodded, "Yes, electric car."

"But it seems that China has just begun to invest in research."

With the development of modern science and technology and the improvement of human life quality, oil resources are facing a crisis, and the earth's ecological environment is deteriorating day by day. When every country sees the crisis, new energy industries are born. Oil, no matter what is underground,

No matter how much is buried, sooner or later it will be used up. Wind energy, solar energy, tidal energy, etc. have all begun to be invested in in-depth research.

"Grandpa, the project that grandpa is researching is a new generation-changing new energy project. The real difficulty of electric vehicles is the battery. But grandpa has solved it now. You said... what a huge project this will be.

Market? Aren’t there fewer bicycles now and no one rides them? Then let them upgrade the industry, from bicycles to electric vehicles, how many bicycle factories will be saved, and how many workers will be saved who are on the verge of losing their jobs?”

Old Man Yun listened very seriously. After his grandson finished speaking, Old Man Yun asked the most important question.

"How much does it cost?"

"Well……"

Yun Miao also forgot to ask about this. He only cared about being happy and forgot about the cost.

"Fuck me"

If the cost is too high, let alone revenge for Xie Yiyi, even those words just said are all nonsense.

"outside

male……"

Yun Miao looked at Shui Yanfeng eagerly, hoping that grandpa could quote him a price he could accept.

"The current cost price per gram is 300 yuan."

Shui Yanfeng quoted the price.

Yun Miao slapped her forehead.

Old Yun looked at his grandson unkindly. This kid was just trying to trick his teammates.

"A battery costs ten kilograms, and it costs 300 yuan per gram. How much do you plan to sell it for?"

Before Yun Miao could say anything, Shui Yanfeng rescued his grandson.

"Lao Yun, you can't calculate the accounts like this. Moreover, what I just said is the current cost price."

Hearing what his in-laws said, Old Man Yun turned his head and looked at Shui Yanfeng again.

Yun Miao also showed an expectant look in her eyes.

"Lao Yun, the battery you are talking about is a lead-acid battery or a dry battery. But graphene batteries are relatively light. And the cost will become lower and lower with in-depth research, until it is acceptable for civilian use. I guess

It only costs a few dollars per gram.”

Hearing what Shui Yanfeng said, Old Man Yun couldn't help but curiously asked: "What kind of graphene are you talking about? Can it really be so cheap? What's the benefit of that?"

Yun Miao blurted out without her grandfather having to answer.

"If graphene can really be so cheap, this new battery can compress the charging time from several hours to less than a minute. In the future, when one-minute fast-charging graphene batteries are industrialized, it will bring about a revolution in the battery industry.

changes, thus also promoting the innovation of the new energy automobile industry. Battery technology is the biggest threshold for the vigorous promotion and development of electric vehicles, and the battery industry is at a stage where the development of lead-acid batteries and traditional lithium batteries has encountered bottlenecks. The development of graphene energy storage equipment

After successful development, if it can be mass-produced, it will bring new changes to the battery industry and even the electric vehicle industry. Grandpa, this is a trillion-yuan sunrise industry. By then, all the cars on our roads will use electric energy technology.

Economical, environmentally friendly, and energy-saving.”

"so smart?"

Old Man Yun was shocked.

Yun Miao nodded.

"The new battery made of graphene material will be smaller in size and weight, and the energy storage density will be increased dozens of times, improving the driving efficiency of the vehicle. Grandpa, what do you think it will be like?
