Metropolis: My IQ is 300

Chapter 148

Chapter 143 A Letter from Old Yuan (for subscription, fifth more)

Chen Fan arrived at the airport, accompanied by someone. At this time, the mask had been taken off.

“Chen, I’m sorry.”

“There is no need to apologize. It is enough to have less contact in the future. I don’t really think that the technology will be sold to you. Don’t think about it. If you use it, we will sue.”

“Uh, this…”

“You lied, idiot, it will be sold to you, don’t worry, at least, she has nothing to do.”

“It’s good if you can understand it. We take care of it very carefully. We have reached the extreme in all aspects. Moreover, protection has another meaning.”

“I understand, my sister-in-law is dead, so she will definitely blow her hair by then, and you can’t afford it. I want more than 200% of the price, right?”

Hold.

“Not too much.”

“So the trade point for import and export?”

“This… you Chen Fan, you are.”

“You said yes or not.”

“Well, yes, the trade tax point will be lowered, and moreover, land you on the land to sign,”

Chen Fan pulled the person in charge aside and said, “What information did I give you?”

“It’s used, it’s already changing people. A new faction will cooperate with you China. Don’t worry, someone will visit in the past and try to sit down until the tax on trade is zero.”

“Well, this is the best, which group of people?”

The person in charge said: “That group of people is actually easy to handle, Chen, you think, if you are a politician and you go up, will you allow the people before you to be happy? Isn’t it, if you become the principal, before Principal of “Are you waiting to see you”?”

“I’ll see you, why don’t you see, okay, I won’t talk about it with you, I just said casually, you take it seriously, anyway, I recorded it, besides, let the cube for you, in fact, it is a light bulb.”

Hold.

Is this the conspiracy of Xueba?

It’s really bad enough.

Actually, this may be politics. Chen Fan also understands a little bit. Tao Yaoyao is responsible for the details. This is impossible. Chen Fan is really not good at it.

Get on the plane and return.

Qiu Hua waited at the airport.

He received his 223 wife, and the two hugged each other.

There are many reporters here.

But Chen Fan and Tao Yaoyao took a look, and Anna next to him said, “Give you a hat.”

With their hats on, the three of them ran away.

These very irritating things really hurt the brain.

“Looking for food, looking for food, starving to death, the food over there is really unpalatable.”

Anna asked directly, Tao Yaoyao contacted here.

Found a place, sat down, Chen Fan opened a letter.

“what is this?”

“A letter written by the old gentleman, saying that if I come back safely, I can open it, and if I have an accident, I can also open it.”

Tao Yaoyao nodded, choosing not to watch.

The letter opened, it was written.

“Chen Fan, biology, I’m really happy that you can come. In fact, it’s really not easy to walk all the way and fumble.”

“In the early years, the famine could really starve people to death. I still don’t think it is enough, it’s really not enough. I think we can have more food for everyone.”

“Although the increase in output may cause the people to make no money, I still hope that everyone will hold on.”

“I don’t like the feeling of being hungry.”

The meal was brought up, Tao Yaoyao picked a piece for Chen Fan, Chen Fan took a bite, and continued reading.

“If something happens in Maple Leaf Country, go to this place and find these people. These people can protect you. These are my good friends.”

Chen Fan looked at the list, and said nothing. After reading it, he shredded the page and put it in the water glass.

Swallowed in one breath.

This is stability.

Chen Fan continued to look down.

“Hybrid rice, this time, is not the real subject. This time the subject is genetically modified technology. In other words, using your technology to conduct hybrid experiments in biology is the core.”

“In addition, you said that changing the natural growth pattern can actually be done to a certain extent, but it is difficult, really difficult, to complete the growth of a tree in more than ten days, unless you have a lot of money to lay it. ”

Chen Fan continued to watch.

“I will take you a lot of roads, see a lot of things, and there will be a lot of people with you. You are prepared, this may be a very long road.”

When the letter was over, Chen Fan put his heart down, looked at the people around him, and said, “I may follow Mr. Yuan for a while, do you want to follow?”

“Okay, I like traveling the most.”

Anna nodded, and Chen Fan said, “Not a tourist.”

“That’s okay, what do you do, can you tell me specifically?”

“I have to prepare something first, portable, I have to optimize it, and I have to equip an arm measure, and related things, have to prepare, and then trigger. This time, I am actually looking for a substance. ”

“Matter? Element? Or particle?”

“It’s a substance, a substance that can change the growth cycle. The world is in a reciprocal cycle. I think there must be such a substance, but there are not many.”

Nature is mysterious. This time, Chen Fan is challenging a more rigorous subject.

A substance that can change nature.

I found it, Chen Fan could sit there, and in almost a month, he quickly completed the desert treatment.

In other words, let the world be deserted, then the home that Chen Fan needs will actually be completed.

Do whatever it takes. After returning to Peking University, Chen Fan was locked in the laboratory.

At this time, Qiu Hua’s 5g technology conference was also underway.

“Let me create value with 5g instead of discussing how much money I made with 5g.”

Qiu Hua delivered a speech.

“4G has not been rolled out on a global scale for a long time. Is it too early to develop 5G technology? From the perspective of the development trajectory of the communications industry, other than 1G, other different generations of network standards coexist, and the more time it takes to replace It’s getting shorter and shorter. The replacement intervals between 1G, 2G, 3G, and 4G are 12 years, 10 years, and 8 years, respectively. From 4G to 5G, it is estimated that it will only take 6 years. Zhang Feng, chief engineer of the Ministry of Industry and Information Technology, said that this year In the third quarter, China’s new 4G users accounted for about 40% of the world’s new users. It is expected that China’s 4G user scale will be the same as the network scale in 2015, ranking first in the world. With the continuous evolution of mobile network technology, China’s Internet business model continues Innovation, mobile taxi rides, mobile e-commerce and other O2O services are in the ascendant. The rapid development of 4G not only makes the industry full of expectations for 5G, but also lays the necessary technical foundation for the evolution of 5G technology.

In addition to Qiu Hua’s speech, other departments also made a lot of speeches.

. ”

“China can be regarded as a pioneer in the world’s 5G technology research and development. Yang Chaobin clearly stated that Huawei will invest US$600 million in 5G technology research and innovation in the next five years. This does not include 5G product research and development after the technology is mature. , “In the future, investment at the product level will far exceed this number.”

“Xu Zhijun said that with the prosperity of the mobile Internet, smart applications and smart devices will be put into commercial use on a large scale, the amount of mobile data will increase substantially, and data traffic will create more value. Mobile networks will become as critical as transportation and energy in the future. Infrastructure, and network technology will also become an important engine for economic development.”

For telecom operators, the development of 5G technology is undoubtedly a huge piece of good news. According to data released by the Ministry of Industry and Information Technology a few days ago, the non-voice business revenue of basic telecommunications companies accounted for% of the total revenue. According to Li Zhengmao, vice president of China Mobile, in recent years, operators’ business revenue structure including China Mobile has undergone tremendous changes. Voice business revenue continues to decline, and data traffic business revenue grows rapidly. In the future, digital service business will become a new business for operators. Business growth point.

5G will create technical conditions for operators to develop digital services. Yang Chaobin said that in the 5G era, the network connection of the entire society, including the relationship between operators and other industries, will change. Operators will enter the vertical industry fields such as smart home and remote control. This will be an important growth opportunity for operators in the future. Operators can provide enterprises and users with more diverse communication services. ”

The overwhelming news made everyone understand that the real era of 5g has also arrived.

As a practical point of Peking University, these students really experienced the application of 5g technology.

A mobile phone, what is really called fast.

Really fast.

Song download is just a click away.

Watching a movie, jumping infinitely.

And an up host of station b, student He’s speech about 5g, attracted a lot of people, and even many news media used this video for publicity.

What is cross-age thinking?

Time goes forward. When 4g is not released, people’s concept of 4g is also very vague.

But after it appeared, everyone actually started to think about it, and began to discover that 4g can really be used.

With this kind of inspiration, everyone seems to understand one thing, we will be witnesses of history.

In other words, we will become true historical inheritors.

Chen Fan received three invitation letters.

The first one is an invitation from the World Information Technology Exhibition. I hope Chen Fan can come and exchange ideas, but Chen Fan rejected it.

The science and technology conference held by Chen Fan actually conflicts with the information technology exhibition. When the money enters Chen Fan’s side, don’t think that Chen Fan will take it out.

What is the core of retaining talents?

As long as there are enough global summits in China, talents will naturally remain.

Instead of kidnapping them morally.

Of course, people who are really immoral, who don’t know the weight of their own land, should leave.

The second letter is from Charlie. Charlie hoped that Chen Fan could serve as a judge of the Mathematics Association, but Chen Fan rejected it again. Of course, it was reserved.

Charlie hopes that Chen Fan can come to be a famous person.

The third, a bit interesting, is the invitation of Mensa members, the fifty smartest people in the world, to invite Chen Fan to solve the world’s public problems, which seems to have something to do with the volcano.

But Chen Fan refused.

The reason is that there is no time.

At this time, Chen Fan is learning the most basic things with Yuan Lao.

Genetically modified technology.

“. Agrobacterium-mediated transformation

Agrobacterium is a gram-negative bacterium that is ubiquitous in the soil. It can chemotactically infect the injured parts of most dicotyledonous plants under natural conditions and induce crown gall or hairy roots. The cells of Agrobacterium tumefaciens and Agrobacterium rhizogenes contain Ti plasmid and Ri plasmid, respectively, with a section of T-DNA on them. After Agrobacterium enters the cell by infecting plant wounds, the T-DNA can be inserted into the plant genome. Therefore, Agrobacterium is a natural plant genetic transformation system. People insert the target gene into the modified T-DNA region, use Agrobacterium infection to realize the transfer and integration of foreign genes into plant cells, and then regenerate transgenic plants through cell and tissue culture techniques.

At first, Agrobacterium-mediated method was only used in dicotyledonous plants. In recent years, Agrobacterium-mediated transformation has also been widely used in some monocotyledonous plants (especially rice). 2. Particle gun-mediated transformation

Using gunpowder explosion or high-pressure gas acceleration (this acceleration device is called a gene gun), the high-speed microprojectile wrapped with the DNA solution with the target gene is directly sent into the intact plant tissues and cells, and then through cell and tissue culture technology , Plants are regenerated, and the transgenic positive plants are selected as transgenic plants. Compared with Agrobacterium transformation, one of the main advantages of gene bombardment transformation is that it is not restricted by the range of recipient plants. Moreover, the construction of its vector plasmid is relatively simple, so it is also a widely used method in transgenic research. ”

Looking at the information in his hand, Chen Fan said: “These are the most advanced at present?”

“Well, the collected information you have seen is the most advanced, and it is beyond the reach of Xiaomei.”

“this is?”

“Handwritten, little by little accumulation. The so-called microinjection methods that you can find are all produced later. When there is no technology, these are the dumbest and most basic.”

Chen Fan understands the importance of tidying up what is written on this paper.

Remember after reading it, and then burn it.

This is the core.

“So, where are we going?”

“I don’t know, you choose.”

Chen Fan thought for a while and said, “I think I should be able to locate the location of that kind of material.”
