In order to understand the role of software, Zhang Yu obtained the basic abilities of computer programming, hacker knowledge, network knowledge and mobile phone software from the system. Pen, fun, pavilion www. biquge。 With the increase of knowledge base, Zhang Yu also has a certain understanding of mobile phone software...... Zhang Yu analyzed the process of running the mobile phone and found the suspicious programs in it.

This running program, disguised as one of the built-in gadgets of the system, is not visible as anything special even if it is opened.

Zhang Yu also downloaded the relevant software to analyze and study the process...... It soon became clear that the process had special requirements for some system permissions. The process can not only automatically start the call recording function, but also locate your own mobile phone in real time, and send the exchange information to another mobile phone with the same software installed.

Zhang Yu quickly studied the functions of the software! To say that this mobile phone software is not a high-level application, at most it is a mobile phone software similar to multi-person interaction. It's just that the maker of the software has cracked the same kind of software and added a recording function, which can be regarded as a cracked modified version of some kind of software of the same type!

The software is disguised as a certain program that comes with the mobile phone system, the icon looks very inconspicuous, and at the same time it is hidden in the folder of system functions by Guo Yutong, if the user does not carefully check each system function, it is really not easy to find that there is a special software in the mobile phone.

Zhang Yu knows that the built-in core function of this software actually comes from a two-way interactive software, not only can the other party monitor his mobile phone, as long as he makes a slight modification, he can also monitor the other party's mobile phone.

Zhang Yu wanted to say that he now has a certain basic software production ability, as well as the ability to hack and crack, he downloaded some programs, began to try to adjust the address data in the memory of the mobile phone, and soon restored the two-way monitoring ability of the software in the memory.

A location map immediately appeared on the screen of the phone...... Although Zhang Yu is a little unfamiliar with the address and location of the other party, it goes without saying that he also knows that nine times out of ten it is Guo Zixian's mobile phone.

Good boy, you dare to blatantly set yourself up.

Zhang Yu secretly calculated with an unhappy expression that he would definitely find out what Guo Zixian's plan was to deal with him. In the end, let him lift a stone and shoot himself in the foot, so that he really knew that whoever wanted to find him Zhang Yu's trouble was actually looking for his own trouble.

......

Zhang Yu was studying his mobile phone upstairs...... And Guo Yutong's throat screaming downstairs was about to smoke, but there was still no response.

Guo Yutong could only sit weakly in front of the bathroom door, and he didn't know what to do...... Now I am calling the heavens and the earth to be spiritual. The key is whether Zhang Yu went home or not! I don't know. If Zhang Yu is at home, it still makes sense for him to shout and scream. If Zhang Yu hadn't gone home, wouldn't his efforts have been in vain?

Guo Yutong can't make phone calls at the moment, no one responds to calls, and he is hungry and hasn't eaten for a day, only drank two bottles of drinks, and now he has no strength at all.

Could it be that your voice is too quiet!

Guo Yutong sat on the ground and rested for a while, and suddenly an idea occurred in his mind...... But after thinking about it for a while, I also knew that my current situation didn't seem to be able to make a louder voice, and shouting didn't seem to be a clever way.

Guo Yutong fought hard, got up again and walked around the bathroom...... I found that although the bathroom was luxuriously decorated, there were not many tools that could be used. She picked up a couple of plastic bottles of toiletries and looked at them, then shook her head, as if it didn't seem to have much effect. followed her to the recliner and turned around a few times, and found that the fulcrum of the recliner was still twisted to the ground with screws, and she couldn't use it herself.

"What can I do about this?" Guo Yutong looked around with a worried face, and his eyes lit up...... I walked to the side of the toilet and moved it with my hand, and saw that the lid of the water tank was actually moving.

That's right! This thing should be usable! Guo Yutong knocked at the same time, and felt that the hardness was still good.

Guo Yutong took the lid of the toilet tank, came to the door of the bathroom, and smashed it on the door at once...... This time I really saw the effect, not only did I smash it with a loud sound, but even the gate that hurt my hands when I clapped it was smashed out of a pit at once. followed Guo Yutong as if he had found a good way, waved the lid of the water tank, and slammed it on the door of the bathroom, hoping to let Zhang Yu in the room hear his voice calling for help.

......

Zhang Yu was upstairs, but in fact, he really couldn't hear Guo Yutong's slamming the door at all, which shows that the sound absorption effect of this house is good. However, although Zhang Yu couldn't hear it, he could see it. After taking care of the mobile phone, he found that Guo Yutong was smashing the door with the toilet lid.

This scene made Zhang Yu quite unhappy! I wanted to go downstairs and ask the other party to stop this kind of sabotage that harmed others and was not beneficial to himself. But then he stood up and didn't take a few steps, and then gave up on this idea. Since she plans to teach the other party a lesson, then she can smash it as much as she likes! Anyway, with such a thick door, it is impossible to smash it open with just a toilet lid.

Zhang Yu held back the unhappiness in his heart, and decided not to deal with the other party, turn off the lights and sleep, and come out of sight.

......

Guo Yutong smashed it for a long time, it can be said that he was tired to death, although the toilet lid can be waved by himself, but after all, it also has a certain weight, and after a long time, he is also sweating profusely, his hands are sore, and now he even smashes the skin with beautiful patterns on the outside of the door, and there is still no reaction outside, if there is no one in this house tonight, it is meaningless to smash it like this.

Guo Yutong touched the heavy solid wood bottom of the wooden door with his hand, and knew that it was impossible to smash such a heavy solid wood door with just a toilet lid...... Guo Yutong thought of this, looked at the door lock, and thought to himself, maybe he could use this toilet lid to smash the door lock.

Guo Yutong had this idea, and immediately smashed the handle of the door lock with the toilet lid in his hand...... After a few slams, the doorknob gradually tilted to the side.

Guo Yutong was excited when he saw this, and the strength in his hand also increased a lot, and then smashed it a few more times, and the doorknob was smashed to the ground at once, bounced a few times, and made a crisp sound at the same time...... Guo Yutong was almost jumping up with joy when he saw this, he knew that he could leave here so easily, how could he use so much effort, it seems that he will encounter things in the future, he must definitely face them calmly, how can he say that he is also a legal beauty, and he can lock a door!
