Chapter 143 The Return
Early the next morning, Yu Fan took a car to the Behavior Analysis Department of the XA Municipal Bureau to find Chen Jianyang and Guo Na.In the past, when Chen Xingyang asked Yu Fan to help, he would be picked up by car, but this time Yu Fan asked him to come by himself, which really surprised Chen Xingyang.

Yu Fan stood waiting at the gate of the Municipal Bureau, while Chen Xingyang ran out from inside to guide Yu Fan in.After not seeing Chen Xingyang for a few days, Yu Fan found that he had become more energetic, which may be the reason why he was radiant after being promoted.But then again, Chen Xingyang has always been full of energy. This kind of carefree personality is completely opposite to Yu Fan's sensitive personality.

Chen Jianyang looked at Yu Fan overjoyed, and when they met, they gave him a big hug.

Yu Fan spoke first: "Where's Guo Na?"

Chen Xingyang let out a smirk, and said: "Oh, I've been thinking about our beautiful little Guo since I came here. I found out last time I was in LZ. You are very boring."

Yu Fan smiled embarrassedly and said, "None of your business, I'm just asking. By the way, how is the case going? Did I catch your last train?"

Chen Xingyang's expression was not as turbulent as before, he restrained himself a little, and said: "There is progress, but there are still a lot of troubles, let's not talk so much, I will show you our new office space." Yu Fan walked in.

Behavior Analysis is here.

But this surprised Yu Fan. This is just a room on the second floor of the basement of an old building in the city bureau. The air is full of musty smell. This room looks like it was remodeled from a warehouse.The entire Behavior Analysis Department consists of one hall and one room. The hall is about 15 square meters and has a large screen.The room is about 360 square meters, very narrow, and this small room inside should be Chen Xingyang's office.Yu Fan used to think that this is such a tall office space, there should be several rows of computers and a large [-]-degree screen.The result is so low...

Guo Na was cleaning the table. Obviously, she knew that Yu Fan was coming, so she specially cleaned up a desk for Yu Fan.In addition to Guo Na, there was another young man typing away, who seemed to be a secretary or a clerk.The Behavior Analysis Department, which sounds tall, has only four people including Yu Fan.

Yu Fan complained: "Didn't you say you were promoted? But why do I feel that you were sent to the frontier?"

Chen Xiangyang is still full of confidence: "It's good enough to set up a department for us alone, what else do you want? After all, this is just the beginning, and I feel quite content with such a big place for us, freedom. Don't look at it In the basement, the mobile phone signal is not bad."

Yu Fan smiled wryly.

Guo Na looked up and saw Yu Fan, and greeted him kindly: "Brother Yu, you are back."

Yu Fan looked at Guo Na and said affectionately, "Guo Na, thank you."

Guo Na looked at the table, and said with a smile: "Brother Yu, you are too polite, I know you are coming today, and I will clean up a table for you.

Yu Fan also smiled slightly, and said, "I mean, thank you." While speaking, he gestured for a small piece of paper with his hands.

Only then did Guo Na realize that Yu Fan was referring to the small pieces of encouragement that Guo Na asked Amao to bring to Yu Fan in the past few days.

Guo Na blushed, nodded slightly, and whispered, "Brother Yu, you're welcome."

Chen Xingyang was next to Monk Zhang Er, puzzled, and teased: "What are you two talking about? What little secret?"

Yu Fan changed the subject and said, "Okay, Lao Chen, let's get down to business, where is the progress?"

Chen Xingyang's expression became serious, and he signaled Guo Na to turn on the big screen.Chen Xingyang told Yu Fan while playing the video: "In the past few days you have been away, we have interrogated hundreds of people and arrested some key members scattered in XA. This organization has basically been wiped out by us. , only their chairman has not been arrested, and this person is named Liu Yan."

Yu Fan: "There is only the last one left. It will be a matter of time to catch him. Ask more people who have been in contact with him, and you should be able to get the information you want."

Chen Xingyang sighed, and said: "The blame is here. This Liu Yan is extremely low-key. Except for their boss Jiang Rantan, no one has seen this Liu Yan. Even many people have never heard of it. Ran hydrocarbon said that Liu Nian usually contacted him through a single line, and he didn't know where Liu Nian was."

Yu Fan had a flash of inspiration: "Single-line contact, isn't this the same as Hong Chashi's contact method?"

Chen Xingyang nodded: "Yes, Jiang Ranhan keeps saying that they are an ordinary MLM organization. But I always feel that it is not that simple. Moreover, Jiang Ranhan himself said that he has never heard of any Hongchashi, no I know what that is." While speaking, Chen Xingyang played the video of interrogating Jiang Ranhan on the screen.

Yu Fan raised his chin, watching the video and thinking.

Guo Na added next to him: "Brother Yu, we have also considered another possibility. Do you think there is no such person as their chairman Liu Yan at all? Could this be a fictional character created by Jiang Ranhan?"

Chen Xingyang followed Guo Na's words: "In this way, this cunning Jiang Ranhan can lead us by the nose and let us keep investigating a person who does not exist at all. And fabricating such a fictitious behind-the-scenes man can also To a great extent alleviate their crimes."

Chen Xingyang and Guo Na seem to make sense in their analysis.

"No, Liu Yan really exists." Yu Fan interrupted the reasoning of the two, staring straight at the big screen.

Chen Xingyang didn't understand why, and asked, "Old Yu, how do you know?"

Yu Fan said calmly, "Because Jiang Rantan doesn't drink water."

Chen Xingyang and Guo Na stared wide-eyed, confused by Yu Fan.

Yu Fan explained: "When a person is lying, the blood circulation in the oral cavity is accelerated, and the water in the cells will be lost rapidly. When the internal environment of the human body is short of water, the osmotic pressure increases, which stimulates the hypothalamic osmoreceptors and transmits them to the cerebral cortex to make us produce Uncontrollable thirst. At this time, no matter who is drinking water, but you see..." Yu Fan pointed to the big screen.

Chen Xingyang and Guo Na turned their heads and stared at the big screen.

Yu Fan: "A cup was placed in front of Jiang Ranhan, but he talked non-stop for more than ten minutes without drinking a sip of water. First, it shows that his thoughts are coherent and he doesn't need to drink water to procrastinate his thinking The following plot is basically a memory rather than a fabrication. Second, he has no sense of tension at all, so he will not be thirsty, and he will not use the action of drinking water to relieve anxiety. So I think this is not a lie at all state."

Chen Xingyang thought about it carefully, and it really made sense, but Chen Xingyang asked again: "Then what should we do next?"

Yu Fan smiled and said: "When you find that there is a dead end ahead, take a step back, the sea and the sky will be brighter."
