Half an hour was not so much about preparation, but as time for Lu Qianfan to solve the mystery. Tang Jie did not tell him the location of the meeting, indicating that Lu Qianfan needed to deduce the meeting place by himself. Lu Qianfan used his smartphone to look through the situation book and on-site photos sent by the client, as well as the inquiry transcript of the office, and felt that he should become a primary school student who saved the world with football.

"Is there an unknown monster in the city?" Before Lu Qianfan scratched his head in time, he put his hand down and turned to frown to indicate that he was thinking. You can't scratch your head, and if you scratch it again, you'll be bald. There is an energy barrier set up at the boundary of the city using magic energy stones, up to 8,000 meters in the air and down to 50 meters underground, making it difficult for demonic beasts to enter the city. However, there are always some strange monsters that can jump over the energy barrier. The City Defense Team was established to deal with these monsters, but there are always some bizarre things that make it unclear whether they are the ghosts of the monsters, so the City Defense Force will hand over this kind of thing to a private office that takes on any task to investigate. As long as the investigation by the private office confirms that Warcraft is the culprit, then the City Defense Force can be dispatched.

This time the commission seems to be a bit complicated. A teacher at Seongnam Jingxue High School was witnessed dead, and some students even took pictures. However, when the patrol arrived, the teacher's body was mysteriously missing, and the teacher himself could not be contacted. But the next day, the teacher returned to class unharmed. The patrol took it all as a prank on the students, and after a verbal warning, it was over. But two days after the incident, an explosion occurred in the laboratory of Jingxue High School, and a student was caught in the explosion and fell into a deep coma, but the injured student was the student who took the photo. After that, the school husband reported that there was a monster infested, but after three days of continuous searching, the city defense team found no trace of the monster, so the matter became an unsolved case and handed over to the Laughing Shadow Office for processing.

"It's a miracle to be able to find doubts in this bit of material. I'm not an intellectual-minded character, am I? Lu Qianfan's fingers took it off the moment he touched his hair. Hold back, scratch it again and you'll be bald. One by one, he scanned the photographs of the scene and the interrogation records from the patrol, feeling that he had found nothing. "Mom, this picture!" Lu Qianfan looked at the photos taken by the students of the scene of the teacher's death and felt that he was blind. "It's so black, you can see a corpse inside?" He maxed out the brightness of his phone's screen, and specially downloaded a mobile phone PS to adjust the sharpness, brightness, and contrast of the photos. But until the end, he could only see a blurry human figure in the photo. "It doesn't look like it's P." Lu Qianfan looked at the picture of his P and said.

"All in all, just know where to go." Lu Qianfan turned off his mobile phone and walked towards a hotel in the south of the city.

At five o'clock, Lu Qianfan appeared at the door of the Shanshui Fashion Restaurant on time. When the meal was approaching, people came and went at the door of the restaurant, and it was very lively, but Lu Qianfan still easily found Tang Jie carrying a briefcase in the crowd.

When he saw Lu Qianfan, Tang Jie nodded with satisfaction. "The time is jammed."

"Briefcase? You're too old a cadre. Lu Qianfan said casually.

"Less poor mouth." Tang Jie said: "We are running out of time, the surveillance of Shanshui Fashion Hotel will automatically cover the video from seven days ago, and we have to verify our suspicions within three hours." ”

"Seven days? Is it so short? Lu Qianfan took out his mobile phone, stood at the door and easily connected to the hotel's WiFi. Tang Jie took out the tablet from his briefcase and said, "The patrol team found that the person was still alive, so they didn't do more investigation. According to the teacher's description, he came to the Shanshui Fashion Hotel at around 7:30 for a light meal. After confirming with his friend, the patrol did not delve further. However, from my investigation, the teacher did not find these friends in his previous relationships. ”

"Relationships?" Lu Qianfan raised his eyebrows. "It's not good to hide your secrets, partner."

Tang Jie slid his fingers on the tablet, and said expressionlessly: "It is not difficult to find people who can drink and eat with him from his social software address book, work circle and life circle within half an hour, and it is not a private thing." It's easy to see that the names of these people are all appearing for the first time. ”

Lu Qianfan looked at the information sent by Tang Jie and said, "Mother, this guy's circle of friends is too extensive. That's a rough look at nearly 2,000 people, right? You figured it out in half an hour? ”

Tang Jie said as he walked towards the hotel: "He lives alone, he has not disclosed his private information in social software, he has not participated in offline gatherings, and his actual interpersonal circle is actually very narrow. I only need to check his classmates, colleagues, relatives and neighbors, plus his social friends who have been in contact with him more than twice. There are six hundred and thirty-two people in total, and it is not difficult to read them in fifteen minutes. ”

"Awesome."

"Nothing difficult." Tang Jie said, "Let's go, let's go talk to the front desk." ”

"What for?"

"Check the surveillance." Tang Jie squinted at Lu Qianfan, not understanding why he suddenly asked such an idiotic question.

Lu Qianfan asked: "How is the performance of your tablet?" ”

"Three generations full of stars, top match."

Lu Qianfan said: "Enough." Lend it to me and I only have my phone with me. ”

Tang Jie frowned and handed the tablet to Lu Qianfan. Lu Qianfan took the tablet and quickly tapped it a few times, as if he was typing something. After a while, Lu Qianfan returned the tablet to Tang Jie. "There are so many people that I need to implant another facial recognition system."

"You have access to their surveillance system?"

"The level of defense of this security system is not very high. As long as you can connect to their hotel's WiFi, you can crack it in a while. Lu Qianfan raised his eyebrows proudly, and then said with a bitter face: "But the passenger flow of their hotel is too large, and I need half an hour to enter a face recognition system." Hopefully we'll find that guy for the rest of the time. The time frame is seven to eight p.m., with three above-ground entrances and one underground parking entrance...... One by one, you can see the Year of the Monkey ......" Lu Qianfan wanted to take back the tablet from Tang Jie's hand, but saw that his tablet was placed in front of him. "I'll go, what are you going to do, the strongest brain?"

After Tang Jie adjusted the playback speed of the surveillance to eight times the speed, he called up the pictures of the four entrances at the same time. "I said, you remember. Once we find a suspected target, we will screen it. ”

"I ...... Go! Lu Qianfan was almost stimulated by Tang Jie's genius to scold. He hurriedly turned on the voice input system. Lu Qianfan has just prepared here, and Tang Jie has already started to report there. "Seven minutes and thirty-one seconds, the main entrance is ...... to the left"

Tang Jie stared at the tablet, his two eyes did not blink, and his eyes moved up and down quickly like a robot. Lu Qianfan learned from his appearance and tried it too, feeling that his eyes were sour to death in less than a minute. "Is this kid a robot?" Lu Qianfan was afraid of disturbing Tang Jie, so he muttered in his heart.

At the door of the crowded hotel, Lu Qianfan and Tang Jie, two teenagers, stood at a distance of one step and looked at each other for a long time, like lovers who had finally met across the sea of people.

Lu Qianfan glared at the rotten girl next to her with stars in her eyes, interrupting the description that was floating in her heart. With such an ambiguous description, how can it reflect the strongest brain of the genius boy Tang Jie? After almost eight minutes, Tang Jiajie put down the tablet and moved his sore shoulders and arms. Lu Qianfan hurriedly took the tablet from his hand and said, "A total of four people have been recorded, so I'll compare the surveillance video after that." ”

Tang Jie nodded, blinking his eyes vigorously. Lu Qianfan tilted his head to look at Tang Jie and asked, "Are you using a blink to make up the frame?" ”

"If you have time to talk nonsense here, it's better to hurry up and compare. We're busy. Tang Jie said: "Don't think that if you save time to negotiate, you will be poor here." ”

"Partner, can you be kind to me?" Lu Qianfan was also helpless. While holding back his right hand that wanted to scratch his head, he thought to himself: "As the protagonist, why are you surrounded by some guys who like to put on a stinky face?" Said that the good beauties chased after them, and the evil ones slapped in the face? It's good, they are all indifferent to themselves like ice cubes, and they have to rely on their own fiery enthusiasm to melt the ice in their hearts. ”

"Is there a result?" Tang Jie didn't intend to care about Lu Qianfan's inner drama at all.

"None of the four were the teacher." Lu Qianfan followed the time they entered the restaurant and the entrance to check the surveillance, and found a clear enough frontal photo of them. "We can now be sure that the teacher lied," he said. What's next? Ask the teacher? ”

Tang Jie said: "That will only startle the snake." Until more clues are found, none of his three friends or he can have direct contact with him. Give me the tablet and I'll see if any of his three friends are coming to the hotel. ”

It seems that Tang Jie is ready to have the strongest brain again. Lu Qianfan hurriedly returned the tablet to Tang Jie and asked, "What are the names of them?" ”

"The teacher's name is Zhou Jia, and his three friends are Wu Yi, Zheng Bing, and Wang Ding." Tang Jie said: "Didn't you read the materials? ”

Lu Qianfan's eyes widened. "Is this the real name?"

"There is no need for a pseudonym in our internal inquiry records."

"No matter how you look at it, it's a fake name......" The corners of Lu Qianfan's mouth began to twitch. Zhou Wu Zheng Wang, A, B, C, D, the author's name is too arbitrary!

"It's my real name." Tang Jie said, holding the tablet in front of him again.

This time, Tang Jie had to check three people, so it took a relatively long time. However, it also took less than half an hour to reach a conclusion. After comparing and screening all the eight people on the list, he confirmed that these three people had really been to the Shanshui Fashion Hotel, and the time of entry was less than five minutes apart. "Do a full set of plays, we may have to deal with four demonic beasts at once." Tang Jie said: "Maybe it's still a guy with the ability to change shapes." ”

"Have there been similar cases before?" Lu Qianfan was curious.

Tang Jie nodded. "There is more than one time, but the demonic beasts that appear are different every time, and there is no way to form a unified countermeasure."

Lu Qianfan resisted the urge to scratch his hair, and if he scratched it again, he would be bald. "Once that's all that we're going to do, what are we going to do?"

Tang Jie said: "Since what teacher Zhou Jia said is false, it means that the student's photo may be real." The real Zhou Jia has died, and the student has been killed because he may know the truth. So, we're going to go to the scene of the crime to investigate, and then try to find clues from the unconscious students, do we still need to teach me this kind of thing? ”

"Am I pretending to be too much lately, I feel like anyone who sees me can despise my IQ." Lu Qianfan couldn't help it, but still scratched his head, looking even more silly.
