Vol 2 Chapter 614: Use of the software

In order to understand the role of software, Zhang Yu obtained the relevant primary skills of computer programming, hacker knowledge, network knowledge and mobile phone software from the system. With the increase of the knowledge base, Zhang Yu also has a certain understanding of mobile phone software... Zhang Yu found the suspicious programs in the process of running the mobile phone.
This running program is disguised as one of the built-in gadgets in the system, and even if it is turned on, nothing special can be seen.
Zhang Yu also downloaded the relevant software to analyze and study the process... It was quickly discovered that the process had special requirements on some system permissions. The process can not only automatically initiate the call recording function, but also real-time positioning of the mobile phone, and send the exchange information to another mobile phone with the same software installed.
Zhang Yu quickly learned the function of the software! To say that this mobile phone software is not a high-level application, it is at most a mobile phone software similar to the multi-person interactive class. Just the maker of the software, cracked the same kind of software, and added a recording function, which is considered as a modified version of a certain type of software!
The software is disguised as a program that comes with the mobile phone system. The icon looks very inconspicuous. At the same time, it is hidden by Guo Yutong in the folder of the system function. If you don't carefully check each system function, it is not easy to find yourself. A special software has been added to the phone.
Zhang Yu knows that the built-in core function of this software comes from a two-way interactive software. Not only can the other party monitor this mobile phone, but it can also monitor the other party's mobile phone as long as it is slightly modified.
Zhang Yu said that he has a certain basic software production ability and hacking ability. He downloaded some programs and began to try to adjust the address data in the running memory of the mobile phone. He quickly restored the two-way monitoring capability of the software in the memory. .
A positioning map immediately appeared on the screen of the mobile phone... Although the location of the other party's address is somewhat strange, it goes without saying that it is the phone of Guo Zixian.
Good boy! Actually dare to blatantly give yourself a cover.
Zhang Yu’s expression is uncomfortable, and he will definitely find out what Guo Zixian has to deal with. Finally, let him lift the stone and lick his own feet, let him really know that whoever wants to find him Zhang Yu’s trouble is actually looking for his own troubles.
......
Zhang Yu studied the mobile phone upstairs... and Guo Yutong’s nephew called downstairs smoked, but still did not respond.
Made Guo Yutong can only sit in front of the bathroom without power, do not know how to do it ... ... now is called every day should not be called the ground is not working. The key is that Zhang Yu did not return home! I don't know. If Zhang Yu is at home, there is still some meaning in his own voice. If Zhang Yu didn't go home, wouldn't he be in vain?
At the moment, Guo Yutong was unable to call the phone. No one should be asked. He still had no food for a day, and he only drank two bottles of drink. Now there is no strength.
Is it that your voice is too small! Can't hear it outside?
Guo Yutong sat down for a while, suddenly suddenly in the brain... But after thinking about it for a while, it seems that there is no way to make a bigger voice in his current situation. It seems that it is not a clever way to scream.
Guo Yutong was strong in spirit and stood up again and walked away in the bathroom... I found that although the bathroom was luxuriously decorated, there were not many tools available. She picked up a few bottles of plastic bottles with toiletries and looked at them. She shook her head and seemed to have little effect. Followed by her, she went to the recliner for a few laps and found that the fulcrum of the recliner was still twisted to the ground with a screw, and I could not use it myself.
"What can I do?" Guo Yutong looked at his face four times and followed his eyes. He walked to the side of the toilet and moved it with his hand. The lid of the water tank was actually active.
correct! This thing should work! Guo Yutong knocked at the same time and felt the hardness was still good.
Guo Yutong took the lid of the toilet tank and came to the door of the bathroom. He suddenly slammed on the door... This is really the result, not only the sound, but even the door that hurts. It was also suddenly pulled out of a pit. Following Guo Yutong, it seems that he found a good way to wave the lid of the water tank and slammed it on the door of the bathroom. I hope that Zhang Yu in the room can hear the voice of his help.
......
Zhang Yu is upstairs. In fact, he really can't hear Guo Yutong's slamming sound. It shows that the sound absorption effect of this house is good. However, although Zhang Yu could not hear, he could see it. After getting the phone, he found that Guo Yutong was using the toilet lid to knock the door.
This scene! To say that Zhang Yu is quite uncomfortable! Originally wanted to go downstairs ~ EbookFREE.me ~ let the other party stop this detrimental behavior. But then stood up and took a few steps, then gave up on this idea. Since I am going to teach each other, how can she love it? Anyway, such a thick door, I want to rely on a toilet lid, it is impossible to open.
Zhang Yu resisted the unhappiness in his heart and decided not to take care of each other, turn off the lights and sleep, and see no eyes.
......
Guo Yutong has been stunned for a long time. It can be said that he is too tired to die. Although the toilet cover can swing, he has a certain weight. After a long time, he is sweating with his hands, his hands are sore, and now he has a beautiful pattern outside the door. The outer skin was broken, and there was still no reaction outside. If the house didn't come back tonight, it would be meaningless to go on like this.
Guo Yutong touched the heavy wood base of the wooden door by hand. He also knew that it was impossible to open such a thick solid wood door by a toilet lid... Guo Yutong thought of this, looked at the door lock, and thought about it. I think, maybe I can use this toilet lid to open the door lock.
Guo Yutong had this idea, and immediately took the toilet lid in his hand and slammed it into the handle of the door lock... After a few clicks, the door handle gradually came to the side.
Guo Yutong’s excitement was broken, and his strength increased a lot. After a few more squats, the doorknob was slammed to the ground and bounced a few times. At the same time, it made a crisp sound... Guo Yutong saw I am almost happy to jump up. I know that I can leave here as soon as I can. I have to spend so much effort. It seems that I have to face things in the future. I have to calmly face it. I am also a legal woman. Can also make a door to lock up!
