When Zhen Lan was in class, only Duan Guoyu could observe the specific situation, but now the get out of class was over. Xiao Zheng Taiyi came out of the classroom with the abortion and fell into the eyes of the grey machine who was responsible for monitoring the corridor and the open area in front of the classroom. However, this task seemed simple, but in fact it was quite difficult to complete.

First of all, it would be fine if the get out of class was over. You should know that it is the end of the last class in the morning. Students and teachers are pouring out of the classrooms, and it is difficult to observe a person at any time in the corridors and corridors, not to mention that Zhen Lan is short, and as long as he is willing, he can slip through the crowd and not be discovered.

Fortunately, Zhen Lan didn't seem to have such an idea. When his thin figure appeared in the passage in front of the teaching building, Huijie finally breathed a sigh of relief. He wiped the sweat that did not exist on his forehead. Huijie once again understood that he was indeed not suitable for such a job that required great patience and eyesight. If it weren't for the automatic link generated by using technical equipment to receive the signal from Zhen Lan, Xiao Zhengtai suggested that Xiao Zhengtai had brothers near him, it would be easier to let him and the mother insect do such a job.

"First mate, Lanzi went in your direction, I lost my target..." In the communication headset, the gray machine reminded Zhen Lan of her whereabouts.

"Where is the last place he appears?"

“To the east, the slope protection downstairs of the Foreign Language Building.”

"Damn it, that location is a magnolia tree that has been around for more than 30 years. Now it is blooming and gathering. Everyone is willing to go there. The angle is not the same as the treetops and people!! I am now in the toilet on the fourth floor. The angle here is not good. I am now stepping on the partition and the old sewage pipe and stylus, and I look at the head. Let me see that the treetops are still the girls in the toilet next to me!!"

In the headphones, the first mate was extremely depressed and entangled. The amateur call and performance between them made Captain Yang and Colonel Zheng, who were listening nearby, look helpless. The three of them were definitely first-class experts when fighting and killing monsters, but they had specialties in their profession, so the tracking job was still a bit immature. Even the first mate, who was known as the strongest among the four, was just tracking and tracking the vehicle driving. This person to the person...

"Don't make noise. The machine immediately moves to point e to observe the flow of people to the east. Pay attention to the road between the Foreign Language Building and the Economic Management Building. Pay attention to concealing yourself. First mate, you don't need to change your location, but find a way to find a better viewing angle. Be sure to keep an eye on the passage downstairs of the Foreign Language Building. Also, although Zhen Lan is small and easy to hide in the crowd, the team of people following Lan Zi has not yet finished work. They have experience following Lan Zi now. If necessary, don't stare at Lan Zi and them!!"

""I understand~!!"

Duan Guoyu's new order instructions were quickly heard from the headphones. The three observation points were indeed too few, and the three were not professional. Not only should they be careful not to be noticed by the target, but they should also be careful not to be noticed by the special trackers of the flower family to always grasp Zhen Lan's movements, and not give the technical equipment they already have... This is indeed a bit difficult. And we must also consider the attention gift created by walking on the street like a absolutely eye-catching person, so Duan Guoyu reminded the player to pay attention to places where no one or few people passed. The actual observation effect would be reduced. Fortunately, Duan Guoyu's mind was quick, and after quickly adjusting the observation points, he also reminded the two of them to start with the trackers.

Sure enough, Duan Guoyu's efforts were not in vain. A minute later, the new news came from the headphones made everyone feel a little relieved.

"Brother Duan. I have moved to point e to observe, and I saw the target... He is turning to the second canteen in the southeast." Since there is no need to do ultra-long-distance observation like Duan Guoyu. The bag of the gray machine does not have a long telescope like Duan Guoyu. It is just an army-specific telescope that acts as its auxiliary observation tool. It quickly put away these things. The gray machine quickly ran through the long corridors and four-story stairs, and reached the next observation point after crossing two buildings.

"First mate, change the investigation location, the machine can only see the back of the second canteen. I need you to go to the direction of the No. 18 dormitory opposite the second canteen and observe Zhen Lan's direction at any time."

"I understand! Where are you, brother Duan?"

"I don't move now. I can see the side door of the second canteen. The grey machine. When you confirm that Lanzi enters the second canteen, you will go to the International Exchange Center building. I need to have a supreme point there to observe it. Note that there are two small flat heads on the top floor where they are doing large monitoring of the entire school. If necessary, you can use their equipment."

"I understand!! But it seems that Lao Zheng didn't tell these people about our actions today. If they refuse or have any excessive reaction..." Huijie naturally knew that it would be a good thing to be able to use these people's equipment. Through their special identities and special technical means, these people can not only connect the school's public surveillance network, but also use the height of the building as a supplementary observation point. It is really a good place for global surveillance. But after seeing these people like thieves who are not as good as they treat class enemies these days, Huijie really has a good impression of these guys who follow him every day.

"Uh...I don't think there will be any problem. If they have any overreaction... don't take action too much, just let them sleep..."

"clear!!"

Hearing Duan Guoyu and Huijie's idea of ​​his equipment and personnel naked, Colonel Zheng in the equipment car smiled bitterly. He naturally understood the intention of Duan Guoyu's words and Huijie's dissatisfaction with these trackers and wanted to avenge his private revenge, but if he immediately notified the person at that point, he would have one of the observation targets to come up with you... Isn't that prove that he is monitoring their communication?! And if he doesn't tell the two people above... I guess he will suffer a little and be knocked down by Huijie and fell asleep...

Not long after, when it was confirmed that Zhen Lan approached the second canteen for dinner, a machine came to knock out the two people at the surveillance point, and had already seen Zhen Lan's call through the surveillance probe in the canteen. It seemed that Colonel Zheng was planning to use these two colleagues in exchange for the content of the subsequent communication.

Zhen Lan's meal speed is neither fast nor slow. At this time, the three brothers also took out some snacks from their pockets to cushion their stomachs. This was the lesson learned by the brothers in the few tracking operations before. The whereabouts of the stalkers were more abnormal than those being stalked. If you have the opportunity and time to enter the catering water, you must seize the time. If you have the opportunity to go to the toilet, you will be even better. Because who knows when the next time you will give yourself a rest, eat and go to the toilet. Therefore, even if you have the conditions to observe in the car, you must prepare some food and drinking water in the car, and of course some empty mineral water bottles to solve the problem of urgency in urine in an emergency.

The benefits of Duan Guoyu letting the gray machine take over the monitoring center soon emerged. After lunch, Zhen Lan's whereabouts of students who did not live in school became a relatively difficult problem. According to the itinerary given by Zhen Lan himself, he still had to stay in the school this afternoon, which means that during the two hours of noon, there was no dormitory nearby to rest Zhen Lan. Either stay in a classroom or read books in the library to pass the time. These two methods are the only way to do when the brothers were still fishing men.

But now the brothers are no longer struggling to spend a few dollars on the Internet fee as before, so Zhen Lan may choose to go to the Internet cafe or even a cafe at the school gate to spend time. When it is impossible to judge the target and the destination, blindly following and tracking is indeed quite painful and easy to expose himself. However, now, as long as Zhen Lan remains in the public area, Duan Guoyu can make up for some places that cannot be seen by the surveillance probe through his own and the first mate's eyes, which is enough to understand Zhen Lan's whereabouts.

It was just surprising that Zhen Lan, who had lunch, did not choose to go out to surf the Internet. She did not choose to pass the time in the cafe and milk tea shop, nor did she go to the library or classroom he liked to go to. Instead, she walked slowly along the campus avenue to a corner and sat down in the corner of the green flowerbed on the side of the road.

When he sat down, Duan Guoyu, Gray Handheld and the first mate all complained secretly. This angle was so fucking so hard that it was so painful that it was entangled. The flowerbed was not tall or short. If an ordinary person sat on it, he would definitely reveal his whole head, but if it were Zhen Lan... If his body shrank a little, he couldn't even see his hair... and what was even more painful was that Zhen Lan sat there seemed to be waiting for something, and her little head looked out from time to time. There was no way to make the first mate who wanted to get close to the past.

Seeing Zhen Lan unexpectedly not going to the library, the tracking seemed to be deadlocked. Although Duan Guoyu had no choice, fortunately Zhen Lan's observation did not seem to be alert to someone, but was waiting for something. As long as Zhen Lan did not notice his three brothers coming to follow him, everything could continue!

It just depends on the person Zhen Lan was waiting for. Although the first mate found a place to observe Zhen Lan from afar and could observe him directly, this purposeless waiting really tests everyone's patience. You must know that among the four people, Zhen Lan's patience is not only far better than anyone else, but also in previous training, it was specially trained specifically for a long-range sniper. She wore a thick Geely suit and lay in a place where mosquito bites in hot weather without moving for a day without moving. This kind of training is not something that ordinary people can tolerate!!

"Brother Duan, it's been forty minutes. Otherwise, it wouldn't work. I'll call Lanzi back with one phone call. We will attend the top ten tortures of the Qing Dynasty. I don't believe that Lanzi can stand it!!"

Although he was blowing cool and cold wind in the air-conditioned room now and did not have to bask in the sun like Duan Guoyu and the first mate, the gray machine was more anxious than anyone else at this moment. The long-term bored waiting had already exhausted his patience. However, the top ten tortures of the Qing Dynasty he mentioned were not the tricks of treating the enemy, but some of the punishment methods between his brothers.

"It's useless. You have been with Lanzi for the longest time. You know Lanzi's personality better than us. As long as you have seen him change things he believes?"

Duan Guoyu denied the suggestion of losing the gameplay. Among the four brothers, the gameplay has the hottest temper. Although the first mate is a bit fierce, his temper is actually gentle. Zhen Lan... Although he is the youngest, his temper is also the most stubborn, and the things he has basically not changed. Hearing Duan Guoyu's reminder, everyone had to suppress their anxiety and continue to wait patiently for Zhen Lan to get up or the person he was waiting for. The nearby Zheng Datong and others were passing the orders of Zheng Datong. They continued to maintain a distance and posture that was exposed but seemed to be uninterrupted as before.

Unfortunately, thirty minutes passed, and it seemed that the person had delayed something today. It was also possible that he had changed the road. When the time reached the thirteen-forty point, Xiao Zhengta finally stood up, and a look of disappointment flashed across his face. He looked around and looked around. Since it happened to be the time for the students to have lunch break, there were not many students and vehicles passing by on the spacious road. Then he looked at the low-key but specially made watch on his wrist. After walking two steps towards the classroom, Xiao Zhengta still suddenly turned around and walked quickly in another direction.

"Damn it!! Zhen Lan is going to go to the roof! The first mate will follow you quickly!"

"That's a big deal, he can see me as soon as he gets on the roof!!"

The sudden turn and quick steps of Xiao Zhengtai caught people off guard. What's even more terrible is that after Zhen Lan turned around a building, he jumped a few times while there was no one there and then jumped to the roof. In this way, not to mention that the machine in the temporary monitoring center suddenly lost its target, even the first mate was in an exposed place that was easily observed from above, so he could not catch up with him, but could only find a place to hide and hide.

The two of them lost Zhen Lan's figure at once, making the situation extremely complicated. The four of them were very familiar with the move that Zhen Lan had just disappeared. If it were on weekdays, the brothers could catch up with their own speed and strength. Among the four, Zhen Lan had the slowest speed and the least strength, but in this way, she would definitely reveal her position and let Zhen Lan notice it. In the absence of being able to quickly keep up, if she wanted to find Zhen Lan's whereabouts again, she could only rely on luck and some character. At this moment, the three people could finally realize the mood of the followers of the flower family when they were often thrown away by several people like this. Although it cannot be said that there were a thousand grass mud horse beasts running wildly in their hearts, there should still be eight hundred beasts...

"The machine detects directly from the windows. Pay attention to the between buildings and the edges of the windows!"

Duan Guoyu's new order was immediately passed. The location of the grey machine was not only the highest point of the whole school, but also a serious room. Although the dark glass blocked the strong light outside, it just gave the best observation and obstruction conditions for indoor people. This is also a very important reason why the trackers of the Huajia family chose this place. However, the path is one foot high and one foot high. It is precisely because this place is a natural and excellent location for outward observation, Duan Guoyu and others naturally had special and targeted training during training. Hearing this, the technicians in the nearby electronic equipment car were able to record the first most valuable and important information on their laptops. It turned out that although they also judged that these people would walk on the roof, they could never find the target. It turned out that they had already understood how to best avoid observation from such places.

Duan Guoyu's reminder made the somewhat anxious gray machine know what he should do. After observing the possible location of Zhen Lan, his scream came again: "I saw Lanzi. He was on the east side of the Electric Science Building, wisp, jumped to the report center, turned northeast, and went down to the treetops, now outside the wall on the east side, the house on the right side of the Yuanlai Hotel, wisp, he came down to the wall and walked, I lost my goal! His last direction was to the west!!"

"The first mate immediately goes west, and if Lanzi appears there, report immediately! Pay attention to the road next to the hotel. If Lanzi walks north from there, report immediately. I stare at the east side of the fence!"

"clear!!"

A series of commands were quickly conveyed in the communication between the three. On the electronic equipment car, Captain Yang and Zheng Dazheng nervously surrounded the map in front of the simple table, constantly marking what Duan Guoyu and others said. Soon, the locations mentioned by Duan Guoyu just now were circled and the locations where Zhen Lan was before were all marked by Captain Yang. This map was the same as the map information in Duan Guoyu and the others. Zheng Dazheng marked the call time on it after Captain Yang marked the location. After a while, by connecting these points with dotted lines, Zhen Lan's possible walking route, distance, and speed clearly appeared on the map.

Seeing the actual time, distance and other numbers on the map, these strength, speed and jump distances that have completely exceeded ordinary people all made Captain Yang and Captain Zheng look a little shocked in their eyes. Although they have also seen the skills of Duan Guoyu and others in the strengthening base of the Zanghua Family, and have a certain understanding of their speed and strength, no one believes that it is their true level under their full strength...

But while the two were still shocked at the true level of these people, from the speakers broadcast at Shishi, Duan Guoyu suddenly heard the voice that was even more incredible than them:
Chapter completed!
