On the morning of November 17, Beijing, Wulian Building, Underground Research Center.

Zhang Fei tiredly walked out of the laboratory in charge of his father, passed through two protective doors, entered the first-level central security area of the scientific research center, and came to Dong Xuecheng's office. When she entered the door, she saw that not only Dong Xuecheng was in the room, but Sha Pingping was also sitting in Dong Xuecheng's office, patting his stomach and burping, he should have come over after breakfast. Sha Pingping has been under house arrest in a scientific research center recently, and according to Zhang Fei, let him learn more and see more here. When Sha is bored, he often comes over to chat with Dong Xuecheng. Sha Ping has rich experience, has seen a lot, and has a lot of stories in his stomach, and Dong Xuecheng likes to chat with him when he is tired to relieve the tense nerves during the experiment.

Dong Xuecheng saw Zhang Fei push the door in, stood up and asked, "How is it, what is the result of Lao Zhang's experimental retest?" ”

Zhang Fei frowned and shook his head.

"What? Flawed? Experiments proved ineffective? ”

"Nope! There were no problems at all with the experiment. The results of the experiment confirmed that in some special circumstances, some people do have the ability to perceive murderous energy. Zhang Fei obviously didn't like this conclusion.

Sha Pingping didn't stand up when Zhang Fei entered the door like Dong Xuecheng, he was still sitting on the sofa with a big thorn, crossing Erlang's legs, his legs that were on the ground were still shaking rhythmically, showing his dissatisfaction with Zhang Fei with his actual actions. But Zhang Fei obviously didn't care much.

"Is the result of this experiment important? Where is the importance? Sha Ping didn't understand why these two men were taking the conclusion of the experiment so seriously.

Zhang Fei glanced at Sha Ping and said: "You are a detective, when you don't understand, go to find clues, find the answers yourself, don't always think about taking shortcuts." After training Sha Pingping, she turned her head and continued to say to Dong Xuecheng: "The technology of shielding internal force particles has been successful, I have already sent someone to test the situation at the scene, and when they send the data from the scene, you can copy it." You go back and ask the people below to arrange the experimental site and equipment first, and when the materials arrive, start the experiment. Your next step will be to develop the usefulness of this shielding technology. ”

Dong Xuecheng nodded in agreement. At this time, a experimenter in a white lab coat knocked on the door and came in, he looked around at the three people in the room, and then focused on Sha Ping, and stopped talking.

Zhang Fei didn't mind and said: "It doesn't matter, Lao Sha is not an outsider now, just say anything about it." ”

"Mr. Zhang, Director Dong, Qi Yunsheng's memory collection equipment had a flash at 8:12:15 and 837 milliseconds this morning, and the flash time lasted for one millisecond. After inspection, the monitoring and maintenance personnel did not find any problems with our machines, and it can be determined that the external devices on Qi Yunsheng's body caused this flash. ”

Zhang Feiteng stood up suddenly, and then she realized her gaffe and slowly sat down again. She glanced at Dong Xuecheng and Sha Pingping, and said, "Okay, we know, you can go out." Oh, by the way, I'm going to check Qi Yunsheng's equipment in person for a while, and before that, you don't have to copy the memories in the device, I'll check it myself. ”

The experimenter said yes and walked out.

Sha Ping took Zhang Fei's performance in his eyes and savored the meaning of her behavior.

At this time, Dong Xuecheng stood up and said: "Okay, you talk first, I'll take a look at the situation of Qi Yunsheng's equipment first, and find out the reason for the flash." Researchers are like this, and when they have a new situation, they can't resist their curiosity. With that, he hurried out.

Zhang Fei stepped forward to close the door and locked the secret lock, she adjusted the glass of the large window to an opaque state, and then she turned around and looked down at Sha Ping who was sitting on the sofa and said, "You should know why I imprisoned you here, right?" ”

"Cut! It's not because I know too much. Sha Ping still sat there with his legs crossed, looking up at Zhang Fei.

"Another reason is that you're too smart. If you're too smart, you'll discover a lot of secrets, and at the end of the day, you really know too much. Zhang Fei smiled and said.

"Thanks for the compliment!" Sha Ping owes himself on the couch.

"Before the Battle of Jingshen Road, you were reluctant to give Qi Yunsheng's address to Yin Zhaojing, until Yin Zhaojing threatened your daughter, and you decided to cooperate with him to find Qi Yunsheng's location. But you have been chasing Qi Yunsheng for the past two years, and you want to get rid of him quickly, so this is very unreasonable, and your attitude before and after is contradictory. There must be something going on in the middle, you must have deduced part of the truth, so your attitude towards Qi Yunsheng will change. I wonder what you found? When did you find out? How did you deduce it? Zhang Fei asked.

"Mr. Zhang, where do you start! At that time, I was just grateful to Qi Yunsheng for helping me find my daughter. So I don't want to hurt someone who just helped me, because I don't really have a say anything about him. ”

"Sand Detective, you and I are not stupid, don't pretend to be confused in front of people who understand. You must have deduced the origin of the Qi Yunsheng incident, didn't you? In this way, if you can tell Qi Yunsheng about it, I will give you the freedom to send you out on a mission, and no longer detain you in this place where you don't see the light of day, how about it? Zhang Fei said with a smile on the corner of his mouth.

Sha Ping's heart was overjoyed, he knew that Zhang Fei couldn't lie to him, so he raised his eyebrows, raised his head and asked, "Can you go anywhere?" Around the world? ”

"It depends on your abilities. If you can reason about it all, then there is no limit, you can go anywhere! ”

Sha Ping sat upright, put down his crossed legs, and said in a detective posture: "You mean Lang Tianya's true identity?" ”

Hearing this, Zhang Fei couldn't help but laugh and said, "Yes! Tell us what you found and how you deduced it? ”

"I'll start with the reasoning process. The first is that the personality is wrong. I only started tracking Qi Yunsheng two years ago, and before I started tracking him, I studied the case file about him as usual, and I felt that something was not quite right. You know, I was involved in his earliest Wudang Mountain case ten years ago. At that time, I had a preliminary personality analysis of Qi Yunsheng, when he was a teenager, Qi Yunsheng was a child who lacked moral concepts, had a stoic personality, was decisive in killing, did not care much about money, and had a slight sadistic tendency. But when I studied his recent case files, I found that this notorious Qi Yunsheng was an indecisive claw in his bones. This person looks forward and backward, and is a bit of a mother-in-law, collected a large bag of tatters that he was reluctant to throw away, and often repaired clothes and processing tools by himself, he was not short of money but was not willing to spend money, obviously this person has gone beyond the scope of frugality, and it is not an exaggeration to say that he is a money fan. These traits do not match his teenage personality traits at all.

The second is his taste. Before the Battle of Jingshen Road, in an unfinished building, I pretended to care about my daughter's affairs and forced him to have an interview with me. That time, I deliberately ordered a large table of dishes, and deliberately arranged that half of the dishes were spicy and half were not spicy. He was obviously quite hungry at the time, and ate a lot. But he didn't touch those spicy dishes with a single chopstick, only picked those dishes that were not spicy and ate them. Qi Yunsheng, as a Hubei native, doesn't eat spicy food, is this normal? I came into contact with the Hetou Village case in Wudang Mountain ten years ago, and I have not forgotten the contents of the case file, and the witness record of the proprietress of the small restaurant in Hetou Village clearly recorded that most of the dishes ordered by Qi Yunsheng were spicy.

"During the interview, he was not strong at all, his eyes were flat and sharp, he kidnapped a person surnamed Jin, but he didn't even move a finger surnamed Jin, which is also not in line with Qi Yunsheng's slight sadistic personality tendencies in the case file."

Detective Sha no longer looked at Zhang Fei, but looked up at the ceiling blankly, and then said: "Of course, it is also possible that he changed his taste later, from eating spicy to not eating spicy." The character may also be sharpened by reality and corrected its sadistic tendencies. So I re-searched the cases involving Qi Yunsheng in the past ten years, and carefully studied the location and chronology of these cases. Guess what I found? ”

Zhang Fei didn't answer, just waited there for him to say it himself.

Detective Sha asked and answered: "Qi Yunsheng has traveled all over the country in the past ten years, but in addition to Taiwan Province, there is another province that he has never set foot in, which is also abnormal. ”

"Which province?" What Sha Ping said was really unexpected by Zhang Fei.

"It's Shandong! He has been to Hebei, Henan, Anhui, Jiangsu, and other provinces around Shandong, but he has bypassed Shandong alone, is this normal? ”

Zhang Fei still didn't speak this time.

"He obviously deliberately did not pass through Shandong. I also used my mobile phone to record Lang Tianya's voice, and later I gave it to a dialect expert for analysis, and he said that although the voice was very good in Mandarin, it still couldn't hide the flavor of Shandong's dialect in individual syllables. I asked him if he had a Hubei accent in his voice, and he said that he didn't have any Hubei accent at all. He did not enter Shandong, first, because he was afraid that he would not be able to control his desire to go home, and second, because he was afraid that his arrival would bring disaster to his hometown.

"So Lang Tianya is not Qi Yunsheng at all, Qi Yunsheng died in a car accident ten years ago, Lang Tianya is the child named Duan or Gen! The student who was interning at the second automobile at the time. He didn't kill anyone ten years ago, and we've been hunting down an innocent person, and he's been hunting for ten years! ”
