Wu Han returned to the hotel, entered the mustard seed bag, and found Xiao Yuanying still curled up in the corner. Wu Han felt a little heartache for this little thing, and he held her in the palm of his hand in the past, and said softly, "Are you afraid, is it okay for big brother to play with you?" Could it be that Wu Han forgot her age? Her age may be as long as the history of Huaxia. Xiao Yuanying couldn't understand what Wu Han said at all, and just observed Wu Han with his eyes. Wu Han smiled and thought, "It's me who was too careful, it seems that she really forgot everything." Wu Han began to tease this little yuan baby for a while, and after passing on some spiritual power to her, he was ready to start his plan in this mustard seed bag. What made Wu Han depressed was that there was no mobile phone signal in this mustard seed space.

Wu Han returned to the room and took out the two mobile phones, then disassembled one of them to reveal the main control CPU, and then input the spiritual power into it. Now Wu Han's control of spiritual power is quite proficient, and he can freely control the strength and direction of spiritual power, which is all practiced by expanding the meridians and acupuncture points. Wu Han was shocked by the dense transistors of the CPU, tens of billions of transistors are arranged in a regular manner here, he doesn't know anything about electronics, how to realize his ideas. Wu Han's research on stamens mainly has two purposes, one is to understand the stamen, to crack the secrets of foreign high-end stamens, so as to upgrade the domestic stamens, profit from it, kill Hongxing, and strengthen my Huaxia. One is to train yourself through the operating mechanism of the stamen and the complex computing environment, so as to lay a solid foundation for a thorough understanding of your own body and the human organism. In the past, tens of billions were just a number for Wu Han, and there was no specific concept. But now Wu Han really sees this number, and can't help but admire the greatness of mankind and the progress of science and technology. There are twice as many transistors here as there are humans in existence, and if each transistor only stays for a second to observe and understand, it would probably take four or five hundred years. Wu Han withdrew his hand that had input spiritual power, thinking that the slices should not be as complicated as the operating mechanism of the brain. Now that research has proven that the brain is divided into several blocks, each with a different function and role, the same should be true for the stamens. Wu Han put his finger on the stamen piece again, and began to operate the various functions of the mobile phone with his other hand, using spiritual power to sense the corresponding functional blocks on the stamen. Wu Han was cautious and highly concentrated, because the speed of electricity was too fast, and the area of the stamen was too small, he tried many times, and found that with his current ability, Wu Han could not track it at all. Wu Han thought for a while and planned to try it with the accompanying method. In the past, Wu Han only absorbed and converted electricity, but now he has to accompany it but not absorb it, which also makes Wu Han have a headache. As soon as the electrical signal came, Wu Han's body subconsciously absorbed all of it, leaving no time for thinking and controlling. Wu Han finally used spiritual power to separate his body from the stamen pieces to solve this problem. Wu Han restarted the phone and felt the power-on state of the CPU after booting, these blocks of electricity operation are the blocks responsible for the most basic operation and use of the mobile phone, and it should also be said to be the core block. Once you've identified the core block, start using the various features of your phone. It was found that some of these functions can be implemented directly through the buttons, and do not need to go through the CPU. After some functions reach the CPU, the area where the main control area is energized is very small, and then the support feedback to the corresponding functional area is considered to be completed. There are only a few functions, and the operation is very complicated, and the transistors in the main control area flash out quickly in pieces and pieces, although the spiritual power can follow, but they can't remember the position at all, the frequency of appearance, and the number of repetitions, which is the area of each transistor. can only be calculated by area, if it is based on the number, Wu Han may not be able to remember the explosion of his head. Wu Han thought about it for a while and decided to block some of the transistors in the main control area when performing these operations to see what reaction would occur. In the few places where it began to be blocked, some functions could not be performed or were not fully executed, and Wu Han tried to write down the specific location and function of this place. Wu Han did not use a pen or other recording tools, but used his brain to forcibly memorize to exercise the function of the brain. Blocking also inevitably has a crash, restart, blurred screen, data confusion, but there is a part of the transistor, after the blockade has no effect on any operation of the mobile phone, Wu Han named it Area A. Wu Han was a little curious, what are these transistors used for? Wu Han experimented repeatedly, and found that the transistors in the A area would be triggered when performing calls, voice, video, chats, communication recording, positioning, navigation, and other operations, but would not. Wu Han thought about what these functions have in common, which can trigger this A area. Individually, some of these features are indeed common to others. But on the whole, it can't be connected at all. In the end, Wu Han had a bold speculation that this may be the legendary backdoor, specially designed to steal personal privacy. Only personal privacy can link these unrelated functions, and blocking these functions in this area A will not be affected in any way. Thinking about this and continuing to think along this line, there should be a place to receive at the back door, how can you find a place to receive it?

Thinking of this, Wu Han used his spiritual power to light up the entire A area and observed it carefully. Wu Han mainly observes the incoming and outgoing circuits, and each function enters a different channel, but two channels are out, leading to the other two transistors, which Wu Han named B and C. When Wu Han triggered Area A, he directed the accompanying electricity to Area B, and with a pop, a puff of black smoke came out, and the phone was scrapped. This strengthened Wu Han's judgment, this must be the back door, and this B area should be the area used to teleport out, and the other area doesn't know what to do yet.

Wu Han took out another mobile phone and searched for it in a targeted manner. Soon I also found an area similar to Area A and Area B, and the same situation occurred in the past exploration, and the mobile phone was scrapped. Wu Han thought that this area might only be triggered by specific circumstances, or it could only be triggered if the other party opened and received it. If it's the first case, it's better to solve it a little bit by actively sending it, but if it's the second case, it's passively triggered, how should it be solved? Wu Han couldn't figure it out for a while, so he could only buy two more mobile phones with the same model as today tomorrow and continue the experiment to see which situation it was.

Wu Han thought that if it was really a backdoor, it would not affect ordinary people like him in the first place, and even if the information was leaked, it would not have a big impact. However, if it is used by state officials, because it is some important and sensitive department, it may be an important piece of information that will determine the fate of the entire country. Wu Han wondered if he should tell these relevant departments about this discovery? What are the names of these departments? Where can I find them? How can I say it? I am not sure if it is not? It seems that I can't find it publicly, and I can't tell them how I operated. There are a lot of problems again, Wu Han wants to solve them one by one if there are problems, and there will definitely be a way.

In the next few days, Wu Han spent almost all of his time in the room except for going out to buy a mobile phone and replenishing his spiritual power. Playing with Xiao Yuanying for two hours a day, mainly to teach her to speak. Wu Han remembered that he should give this little yuan baby a name, and a book title flashed in his mind "Lori Cultivation Plan", although I haven't read it, but I also want to raise her, so it's called Lori. Wu Han pointed to himself every day to say Wu Han, and pointed to Xiao Yuanying and said Lori. This little thing is really smart, and it took three days to understand the meaning. As soon as Wu Han summoned her, he shouted to Wu Han and Wu Han, and took the initiative to float to Wu Han's palm, unwilling to leave. In the past few days, Xiao Lori has been able to have a simple communication with Wu Han, and her demand for spiritual power is getting bigger and bigger. The rest of the time, Wu Han was completely immersed in the study of the stamen of the mobile phone.

During this time, Wu Yong sent everything back, and almost all of the things were not the original, but all of them were replaced with new ones. Fortunately, the metal piece was not replaced, and Wu Han didn't care too much. One is because Wu Han was completely immersed in the mobile phone test and didn't have the heart to care. One is that even if you want the original, the other party may not be able to take it out at all. Wu Han guessed that Wu Yong wanted to find clues about his spiritual power through his items, and whether Wang Jianxin had left him something to hide in it, so these things should have either been disassembled or broken. Wu Han put away the metal pieces and gave the rest to the shopkeeper. This time, Wu Han will definitely not let Ji Kexin leave the only thing for himself, leaving his side, this is Wu Han's most precious thing.

After many days of experiments, Wu Han found that the first activation of the two mobile phones was the C area, and the activation method was similar, basically when operating various functions, there were more sensitive words, such as some special terms that often appear in the government, military, and science and technology. When a certain number of times or days are reached, Zone C is turned on, and then these operations are encrypted and stored. The opening method of the B area of the two mobile phones is different, one is transmitted at a regular time at 24 o'clock every day. But it's not static, it will also be triggered randomly, when the words involved are very sensitive or there is a lot of related content, it will also start the B area for transmission, and the relevant content stored on the phone will be deleted every time it is transmitted. One is opened by the other party, and after opening, it is quickly transferred, and then the backup is deleted and closed.

Wu Han can't trace the transmission of data, and all he can do these days is to be busy cracking encrypted files. Encrypted files can't be played at all in the phone, Wu Han locks the storage area through the storage of the stamen, Wu Han is called D area. The method used by Wu Han is the simplest and most primitive method, but it is very effective, that is, only one number, English letter or Chinese character is manipulated at a time, and then the changing state of the encrypted file is observed. This work is very time-consuming, which is nothing to Wu Han, the key is to memorize the changed state, and then interpret it according to the changes in the document. Today, Wu Han found the shopkeeper and asked him to operate on his mobile phone, say a paragraph or write a few words and send it out, of course, behind his back. Then Wu Han analyzed what the store owner did and what the specific content was through the document. The shopkeeper didn't know what Wu Han was doing, and he didn't have anything to do anyway, and he was very curious, so he cooperated with Wu Han to operate over and over again. At the beginning, Wu Han could only interpret half of the information, but as the number of times increased, more and more correct, and more and more accurate. The shopkeeper is also becoming more and more curious about how Wu Han understands his operation without looking at his mobile phone. Wu Han and the shopkeeper said that he was inventing a decoder that could interpret any information, how powerful it was. The shopkeeper didn't understand these electronic things, and he was stunned for a while, and couldn't stop nodding. In the end, I felt that it was almost over, so I invited the shopkeeper to have a meal and comfort the shopkeeper. I didn't expect the shopkeeper to be able to drink, two people and a case of beer, a meal of five thousand years from ancient to modern China and foreign countries, and at the same time I learned some of the situation of the shopkeeper. The owner of the shop is called Jia Zhilin, who was laid off a few years ago, and opened such a small hotel with the industry left by his father. It stands to reason that the shopkeeper went to the sea to do business relatively early, and there is no cost, basically all the money invested by his parents. Now I should make some money, but the owner of the store has basically changed in the past 20 years, and the store is still the same as it was 20 years ago, but the TV has been changed and WIFI has been added. The proprietress also took her daughter and left with a person who was laid off together ten years ago, because the family was making money. Wu Han also wondered, why? If he doesn't pursue money and doesn't cherish his wife and daughter, is he too lazy? He doesn't want to do anything, or is there some other reason, but Wu Han can't ask it, after all, it's the shopkeeper's private matter. The shopkeeper seemed to have something to say, but he stopped talking, talked about something else, drank a box, and ended the battle.

I've been tired for a few days, and the experiment is almost over, Wu Han wants to relax today, so that Xiao Loli can get to know the world well. I'm ready to go for a walk on the street and take a stroll around. The current outdoor temperature has reached more than ten degrees below zero, but it has no impact on Wu Han now. Even if you wear a T-shirt and shorts, you won't feel cold, Wu Han still wears winter clothes, Wu Han doesn't want people to be judged as an alien or a monster. I wore a hat so that little Lori was inside. This allows her to see the outside without anyone noticing.

Wu Han came to the commercial street to hang out, and he didn't have any special purpose, he just wanted little Lori to see more. When Wu Han saw his favorite snacks, he ordered them on the hour. I picked up ten of the big skewers, and the one I ate was fragrant. Little Lori couldn't eat, so she could only stare dryly, and really scratch Wu Han's hair angrily. Wu Han saw that she was angry and grabbed her hair, okay, and the boss asked for a roasted red sausage again. Little Lori was angry, and a flash of lightning struck Wu Han's head, Wu Han was nothing, and he was very useful. Little Lori couldn't stand it, and almost lost her soul. Wu Han hurriedly sent the little Lori to the mustard seed bag, found a bathroom and plugged in the door, and immediately went in. Wu Han used his spiritual power to inspect this little primordial baby, and found that the primordial infant had become extremely unstable, much smaller, and the blue halo was so faint that it was almost invisible. Wu Han desperately injected spiritual power into the little Lori's body, and the spiritual power was exhausted, and the little Lori saw a little improvement, but at least it couldn't dissipate immediately.

Wu Han held the little Lori in the palm of his hand painfully, and began to think that he should find her a body.
