Xu Mang just clicked on this e-book, but a virtual box appeared in front of him, which said very simple... Whether to accept the current knowledge or not, and there is still no reason to refuse, because there is no option to refuse.

[Do you accept the full content of the "Information Theory"?]

[Yes] [Yes]

Xu Mang looked at the content in front of him with a confused face, in the past, this was a real need to copy by himself, and the process of copying was quite painful, he needed to keep reading by himself, and with a large number of skill points to speed up the process, usually... Watch every day and every night for a few days.

It used to be like that,

Especially when I was in college, it took me almost a month to enter the field of physics as a liberal arts student, and at that stage... It was very painful, even if Xiao Man, who was already his girlfriend at the time, called, he didn't have time to pick it up.

Fortunately, the relationship was relatively stable at that time, and if the relationship was not so strong, maybe my wife would be gone... Yang Yang and Man Man may have been born to other women... Of course, this is only if.

"Wife?"

"I used to self-study college courses... It took almost a month, and you were snubbed at that time, did you want to break up with me at that time?" Xu Mang turned his head, looked at Xiao Man, who was doing yoga, and said cautiously: "I remember that you were quite dissatisfied with me at the time, right?"

"Humph!"

"You're embarrassed to say... Every time I look for you, you say that you are not free, you have to read a book..."Yang Xiaoman thought of what happened in his college days, and instantly said angrily: "Fortunately, I loved you very much at that time, otherwise... Otherwise, with my suitors all over the street, how could there be a place for you. ”

I...

So what to do,

Who let you have this cabbage planted by me.

Then

Xiao Man got up and came to Xu Mang's side, and then threw himself into his arms, but because he had just exercised, he had a little sweat on his body, which was quite fatal to Xu Mang, in fact, he had a little bit of cleanliness.

"Hey, hey, hey!"

"Sweating so much... Don't lean on me, okay?" Xu Mang said helplessly: "Go away, go away..."

Hearing Xu Mang's words,

Yang Xiaoman was instantly unhappy, and said with a pout: "Aren't I also sweating at night... You didn't hold me tightly, but now you can't? What kind of standard do you have? Can you get a face?"

Xu Mang:( ̄△ ̄;)

This... How can this be mixed up!

It's clear that there are two concepts.

"Ahem!"

"Yang Yang and Man Man are here, is it a shame to say this kind of thing?" Xu Mang said angrily: "It's almost thirty people... There is no woman's virtue at all, you used to soak in the pig cage, do you understand? Go take a shower!"

The next second,

Xu Mang was beaten... It's just that kind of gentle fist, and the situation is a little unbelievable, just when the emotions of the two of them gradually heated up, they suddenly found that Xu Yang and Xu Man were staring at the two of them with big eyes.

Xu Yang:(°ー°〃)

Xu Man: (°ー°〃)

What's going on?

Why do mom and dad hug each other?

But it seems that Mom and Dad hug each other every night, is this a pastime for Mom and Dad?

There was a big question mark in the little head, and the two little guys couldn't figure it out, and then Xu Yang turned his head to look at his sister, and the next second he hugged his sister, feeling... Nothing special.

“...”

“...”

I have to say,

Parents are the best mentors for children, Xu Mang and Yang Xiaoman looked at their son and daughter, and the two of them who were about to run for three at the moment were full of embarrassment, don't look at the child so young, in fact, both of them understand it quite well, but the current vocabulary is not enough to express it.

"Oops!"

"You are sisters and brothers, why are you fighting?" Yang Xiaoman hurriedly got up from Xu Mang's body, pulled away the squirming sister and brother, and said angrily: "The two of them were fine just now, but they suddenly fought..."

Xu Mang shrugged his shoulders and said solemnly: "Yang Yang... You're a boy, you can't bully a girl, don't you hear? Look at Dad... I'm often bullied by your mom, of course... This is dad loves mom, in short, you can't bully girls, especially the girls you like, right... And their own loved ones. ”

"Anything else..."

"You'll do it yourself. Xu Mang said.

Then

Yang Xiaoman exploded in an instant, and said angrily: "Are you talking about human words?

Words fall,

Yang Xiaoman glared at his son and scolded angrily: "You are not allowed to bully girls in the future, I know that you are fooling around outside, you stinky boy is dead!"

afterwards

Xu Mang didn't bother to care about his wife's education of children, he silently opened all the knowledge of "Information Theory", and it only took a few seconds for Xu Mang to find that the content of "Information Theory" had appeared in his mind.

And with all the in-depth analysis of the content, I have to say... The fifth level of intelligence is a qualitative leap, whereas it used to be a quantitative change.

Wait a minute!

Isn't it possible to do a comprehensive dissect of any problem?

Xu Mang glanced at the sister and brother who were on the side, who were trained by their mother, silently got up and went to the study, and then locked the door, and then sat in front of the computer and reopened the email.

Then

Xu Mang found that there was a lot of virtual content on the side of the information sent by Professor Yuan Fei, and after clicking on these virtual contents, he saw that it was an explanation and analysis of this question, and with his understanding of this aspect, he couldn't find any flaws at all.

Strong!

It's too strong!

It turns out that the so-called fifth-level intelligence is not cosmic knowledge, it is a faster way of learning, not a direct copy of civilization, and if you want to improve the height of the current civilization, you still need to rely on your own efforts and creation.

"Ugh..."

Xu Mang sighed, he felt that he was too naïve before, thinking that by raising his intelligence to the fifth level, he would be able to enter a new civilization and expand the knowledge of human beings to the entire galaxy, but now even if the system is the system, it will not be able to improve the entire civilization in an instant.

The ascension of civilization requires a gradual process.

Half an hour later,

Xu Mang has completely solved the problem of thousand-kilometer-level quantum key distribution, which is much faster than solving this kind of problem before, but it requires a very large amount of knowledge support, otherwise this ability will still not be available.

In a word...

Knowledge is power!

"Let's talk about it tomorrow!" Xu Mang stretched his waist, and then sniffed his clothes, why did he suddenly have a little aroma... I've never worn perfume before, what is going on?

In a flash

Xu Mang thought of why, it must be Xiao Man... She had just finished yoga before, and was in a state of sweating, and then she was hugged like that.

rise

Xu Mang opened his study and walked downstairs slowly, seeing Yang Yang and Man Man sitting on the sofa and staring at the TV seriously... Xiao Man's education is quite effective, at least after a criticism, the two little devils are honest in an instant.

"Wife?"

"How did you educate?" Xu Mang came to the kitchen and asked Xiao Man, who was doing it, "This... That's a good result!"

"Of course it's a beating!"

"I'm actually quite confused... Why are you not afraid of beating?" Yang Xiaoman held a kitchen knife and said while chopping vegetables: "It's useless to scold... I'm annoyed. ”

Words fall,

Yang Xiaoman suddenly drove the kitchen knife to the side of Xu Mang's neck, and asked solemnly: "Do you want to make a *child* at night?

Xu Mang: ???

...

HKUST,

Professor Yuan Fei and other colleagues were working on the issue of 1,000-kilometer quantum key distribution, and although they approached Xu Mang, the news they received was not so good, and Xu Mang took a negative attitude towards the plan of the University of Science and Technology.

Also...

Not to mention Xu Mang, even if it's Yuan Fei and the other professors, including the entire team... are a little worried about this plan, after all, this is an unimaginable thing in the world, 3,000 kilometers of quantum key distribution, what is this concept?

No one can do it!

"Huh?"

"Academician Xu didn't say... Can it be solved in a week?" an expert present asked curiously: "Now that a week has passed... When is he going to help us out?"

"How is that possible!"

"Academician Xu is in Rui *dian, how can he solve it for you now?" Yuan Fei smiled bitterly: "And now Academician Xu is very busy, he has a lot of things on his hands, let's not bother him..."

Hearing Yuan Fei's words,

Everyone couldn't help but sigh, indeed... Academician Xu's current identity is not what it used to be, and it takes a lot of face to ask him for help, and this time I was able to contact him entirely because Professor Yuan Fei and Xu Mang had cooperated before.

presently

One of the difficulties of this project was the bit error rate, and Yuan Fei and several others had an initial solution, which was to systematically optimize the existing equipment, including the use of cutting-edge signal capture, alignment and tracking systems, as well as synchronization technology.

But...

These optimization techniques can only solve the superficial phenomena, and the deep things cannot be perfected.

Of course, this is only a small problem of many problems, as well as the practical application problems of transforming into high security, the speed of key generation, the compatibility of wavelength with telecom optical fiber networks, the integration of optical fiber networks and quantum communication networks, and so on.

These need to be addressed... But Huaguo's current technology doesn't seem to be able to do it.

"What should I do?"

"It will take at least ten years!" Yuan Fei smiled bitterly: "And this is still the most ideal stage, every problem... It takes a year, and after ten years, it will all be solved, but there will definitely be various problems, and it will be confusing again. ”

Words fall,

Professor Yuan Fei sighed and said silently, "Let's work together..."

suddenly

The phone rings,

Yuan Fei frowned, he was not very happy to answer the phone at this time, but he picked up his mobile phone and took a look, and found that it was Academician Xu calling.

"Shh

"Academician Xu is calling!"
