The three of them listened to the prompt sound in surprise, looked at the open sensor door, and tacitly made the same action.

"Yangyang, your card permissions have been modified?"

"I didn't know, I actually came in! It's actually in! Hahaha! Yang Yang smirked.

Before he finished laughing, he heard the familiar voice of the uncle on the radio, "Meng Chaoyang, please take your two friends to the monitoring building quickly, yes, it is the tallest building in front of you." "It was broadcast three times in a row.

As soon as he became a thief, he was caught, and Yang Yang led the two of them to the tallest circular building in the middle of the area in frustration.

The monitoring building lives up to its name, standing on the top floor of the building, the entire CAS building complex can be seen at a glance, looking into the distance, the entire Jianyi security zone is also in full view, it is easy to do this before the end of the world, and it is very powerful to do it after the end of the world.

The buildings in the Jianyi area are generally not tall, and they have successfully reduced the attacks of high-altitude mutant birds, but the monitoring building of the National Academy of Sciences does not adhere to this design concept, and the building is extraordinarily high, but no one finds it abrupt.

Taking the elevator to the office area on the top floor, Meng Zhang, Yangyang's uncle Meng Zhang, who had a one-sided relationship, warmly received the three of them, thinking that they would be criticized but received the opposite treatment, which made Yangyang uneasy all the way, for fear that the uncle would settle accounts after the autumn.

Meng Zhang seemed to be the supervisor here, and led them to visit the entire building with a smile, and even visited some of the work experiment areas, which greatly satisfied Yangyang's long-term curiosity. You know, the experimental area has always been closed to outsiders, let alone visiting.

Returning to the main control room on the top floor again, Meng Zhang sent everyone back, leaving only one person, the person turned the chair in front of the screen, and when he saw the front, Chang'an almost screamed, and the man smiled when he saw it, "Do you think it's my brother?" Hahaha, it's not twins, but it's always recognized as the same person, and sometimes it's very distressing! “

Yang Yang pounced happily and shouted, "Brother Jinglu! I miss you so much, if you don't go out to see me, you will know that you will your computer! “

Meng Zhang said with a smile on the side, "Yangyang, don't make trouble, this is Wei Jinglu, Wei Jingxing's younger brother." Didn't Miss An sigh at the strength of the CAS system? This is the lead programmer of the entire system. ”

"So young!" Chang'an sighed, are all computer geniuses particularly young and promising?

"Jinglu was a computer genius and a hacker before the end of the world...... Well, then it served the country. Meng Zhang introduced.

"Meng Zhang! You're not finished, why do you keep talking about the past! Wei Jinglu protested dissatisfiedly, who hasn't been young anymore? Although he is only twenty-two years old now.

"Haha, only by understanding the black history can we know the current bright history."

"Uncle, I found out that you always like to bully Brother Jinglu, be careful I tell grandpa and mother!"

"Yes, what am I afraid of with my aunt's support? Hahaha! “

"Yes, yes, I surrender, the old man and his sister-in-law are my nemesis!"

Watching their family catch up, Chang'an pulled Shen Yu to the side to look at the screens on the wall to have fun.

On the screen is a group view of the entire Jianyi security zone, as well as surveillance video images from all over the place, and Shen Yu told her what the unfamiliar place is.

Chang'an pointed to a residential area and asked Shen Yu, "What kind of place is this?" “

"It's the Qu family, the Qu family has been strong in Jian'an recently, is there any problem?"

"No, I just saw a man in black coming out of there, and I was curious and asked."

"Men in black? Are you sure? ”

"Of course, I can't be mistaken, I don't believe it, but go back and look at it." After speaking, Chang An pulled a chair and sat down, and began to operate on the keyboard for a while, and on the big screen in front of him was the slow-motion image just now.

"See? …… No, I'll slow down any longer, look! Isn't it? Chang'an froze the picture, and there was a dark shadow on the screen that was almost blurred.

"It's a phantom created by the refraction of light! It's an optical illusion! I don't know when, Meng Zhang, Wei Jinglu and Yang Yang came over, Meng Zhang stared at the phantom on the screen and said.

"Absolutely not!" "Not sure." Chang'an and Wei Jinglu retorted at the same time.

"I'll try." Wei Jinglu also sat down next to him as he spoke, expertly typing on the keyboard.

"Wait, change it here, type this." Chang'an said as he followed the modification on the keyboard, and after entering a long list of characters, Wei Jinglu began to add again.

The three people next to him were completely ignored, and finally Chang'an hit the enter key, and the two couldn't help but high-five and celebrate, this kind of chess meeting opponents and confidants feels good.

"Brother Jinglu, Sister An, you cooperate so well! Balls...... The feeling of flying with wings! Yang Yang was impressed and admired.

There was a knock on the head immediately, "Bear child!" Is Chinese taught by PE teachers? Will it be described! Yang Yang rubbed his head and protested, "It hurts!" Uncle, why do you keep knocking me? My Chinese grades are not good in the first place! ”

"Look again!" A figure dressed in black clearly appeared on the screen, and the picture seemed to be playing a series of photos.

"However, there are so many people coming and going in the surveillance, what is the point of you going to such great lengths to prove that this phantom is a figure?"

Everyone suddenly realized that it really didn't make sense, and it was better for a child to understand it.

Chang'an doesn't think so, this is definitely an extremely meaningful thing. "Wei Jinglu, can you call up all the shots of this man in black appearing in Jian'an City?"

"All?" "All?" Wei Jinglu and Meng Zhang spoke at the same time, this is a bit of a lot of work! If you start with the installation of this system, how can it be nearly a year's amount, 24 hours a day, think about this workload is quite amazing.

"What, can't you?"

"Miss An misunderstood, what we mean is that it is undoubtedly a needle in a haystack to retrieve all the images, even if it takes a lot of time to check the last week, not to mention that you want to check all of them?"

When Chang'an heard this, he was puzzled and said, "Isn't it fast to search with images?" I see that you don't have an image verification program set up in your source system? Is it difficult to expand this process to a city-wide search? ”

Seeing that everyone was puzzled, Chang An sat down and continued to type on the keyboard, and the characters jumping on the screen were dazzling, until a waiting prompt appeared on the screen, and ten seconds later, the screen showed 128 search results, so much?

"Shen Yu, come over and take a look, what are these places?" Chang'an moved his position and motioned for Shen Yu to sit down and look at it together, Shen Yu glanced at the half of the chair vacated by Chang'an and sat down naturally.

Meng Zhang pushed the empty chair in his hand and opened his mouth, and pushed it to sit down next to Wei Jinglu without a trace.

In the 128 videos, there is not only the man in black, but also another person, the enchanting king, that is, Ye Zhiqing, the owner of the Blue Night Bar.

Chang'an called up a sketch map of the whole city of Jianyi, and every time Shen Yu read out the name of a place at a point in time, Chang'an marked it with different colors on the map, and after a while, the map was about to become a color dot painting.

A few people couldn't see why, is there any special significance for the frequent haunts of people in black everywhere in Jian'an? If people don't do things that violate the law and discipline, can they still stop them from visiting relatives and friends?

As for the other person who also appeared in the search results, everyone couldn't figure it out, Ye Zhiqing, the owner of the Blue Night Bar, basically stayed at home, what connection did he have with the man in black?

"Could it be like this: the man in black occasionally goes to the Blue Night Bar to drink, and when the surveillance captures his image, Ye Zhiqing appears in the camera? Isn't there someone else in front of you who appears in the camera? ”

"Well, that's possible, too." Chang'an has another guess in his mind, but it just needs to be determined.
