Lao Chen took Xu Tian back to the car, the snowflakes were still falling outside, the temperature had dropped a lot, the stagnant water on the ground had condensed into ice flowers, Lao Chen, who was sitting in the car, closed his palms and rubbed them a few times, and when he just pulled the car door, the skin on his hands was almost sticky with the sticky frost.

"How? See what's wrong? Lao Chen asked Xu Tian.

"That woman is amazing, but I can tell the difference between reality and dreams." Xu Tian sat in the co-pilot and said with his head buried.

"What did you experience in there?"

"Dr. Lin used the surveillance footage to give me the illusion, I don't know what her purpose is, but I care about the content of the dream, just when I broke out of the study and fell down in the hallway, I did have a dream, in the dream I saw two familiar adults."

"Who is it?"

"Red Sister and Duke Cat."

"What? Duke Cat? ”

"Although he is a little younger than the face of the cat mansion, he is still an old man, and there is a boy and a girl who are traveling with the cat duke, I don't know what this dream means, and why do I have such a dream?"

"Is the red sister you are talking about the mother of Siyan and Sitong?"

"That's right! There is also a crying little girl who is walking with Hongmei, who should be Sitong or Siyan when she was a child. ”

"Don't underestimate Dr. Lin's hypnosis, most of the cases that Dr. Lin helped the police handle in the past were that the suspect confessed to the modus operandi after receiving hypnosis, although I think it is also a little incredible, but I still believe that Dr. Lin's hypnosis has a certain influence on people's will."

"By the way, there's one thing I need you to make sure, did you see the swallow go in before I entered the psychiatric clinic?"

"I didn't see the swallow, if I saw the swallow go in, I would definitely stop you, the previous case more or less involved a little swallow, and the swallow is still a patient of Dr. Lin, the most important thing is that the serial case of the previous girl's murder has not been closed, if I see the swallow and Dr. Lin approaching again, how can I not tell you?"

"That's very strange, I obviously saw the swallow next to your car, and Dr. Lin finally confirmed that I did see the swallow next to your car, and I am sure that the swallow must have appeared next to your car, but then the swallow should have entered the psychiatric clinic one step ahead of me, and you should have seen the swallow."

"Are you suspicious of me? I can assure you with personality that I really hadn't seen a swallow before you fainted in the hallway. ”

"Does the psychiatric clinic have a back door?"

"As far as I know, not."

"That's! All the windows of the psychological clinic are welded with iron fences, and it is impossible for a swallow to jump out of the window to enter the psychological clinic, which can only indicate that there was a swallow in the psychological clinic. ”

"You mean there are two swallows too?"

"I don't think it's such a coincidence, the people we suspect are leaking information to us in different ways, as if deliberately telling us that there have always been two identical people, Mr. Jin, Yanzi, and even Dr. Lin has information about this."

"Dr. Lin, I know that she can't have twin sisters, and as for Teacher Jin and Yanzi, the whereabouts of these two people are indeed very strange."

"Let's rule out Mr. Jin first, at least I think the swallows in front of me should not be two people, if there are two swallows, then there is no need for her to play this trick in front of me, because she is doing this trick in front of me is like telling me that there are two swallows."

"I think so, too, there must be some way for swallows to get mixed up in the psychiatric clinic."

"You never left when I was unconscious in the hallway, didn't you?"

"Definitely not, and you weren't in a coma for too long, just two or three minutes."

"But Swallow later came out of the room opposite Dr. Lin's study, and I remember clearly that room was the reception room where the girl was killed last time, and that room had an iron fence welded to the outside of the window, and that we were both blocking the door at the time, so it stands to reason that Swallow could not have walked into the reception room from us."

"I know very well every room in the psychological clinic, there is indeed a welded iron fence, and there is only one corridor in the entire psychological clinic, the living room outside is like the front desk of the psychological clinic, I have been sitting on the sofa in the living room, and there is no second way to enter the reception room in the psychological clinic, the swallow really flew into the reception room from the outside iron fence like a flying swallow."

"That's not right! There must be some way, but it doesn't matter how to find the swallow in the reception room at the moment, the most important thing is why they do this kind of thing, the swallow doing this kind of thing in front of our eyes can only increase their suspicion, they must have their own ideas in doing this, or some other purpose, we have to figure out this matter. ”

"I very much agree with you, from a criminal psychology point of view, every action of the suspects has a purpose, and they will definitely not do meaningless things."

"But at the moment I don't have a clue, why do I do this? What is the purpose of adding suspicion to themselves? This question must be clarified. ”

Xu Tian fell into thought, and when he couldn't solve the puzzle, Xu Tian had to exchange angles with the suspect in his heart, and Xu Tian imagined himself as a swallow.

Xu Tian thought in his heart, if he was a swallow, then what was the point of doing these things? First of all, we have to analyze Yanzi's thoughts, this matter is definitely not decided by Yanzi himself, the instigator behind it must be Dr. Lin, but why did Dr. Lin let Yanzi do such a thing? Is the answer to mess with Xu Tian's nerves? It won't be that simple, because Dr. Lin is a very powerful psychiatrist, if you want to mess up other people's nerves, Dr. Lin will have many methods, and she doesn't need to do this kind of behavior to increase Dr. Lin's suspicion, so since Dr. Lin did this, it means that there must be her purpose.

The answer is close at hand, but Xu Tian just can't touch it.

Recalling the first time he saw Yanzi tonight, Xu Tian vaguely remembered that Yanzi had said some words, and Xu Tian still felt that Yanzi's clothes were very eye-catching.

Thinking of this, Xu Tian raised his head suddenly, and at this moment, Xu Tian, who was sitting in the co-pilot, happened to be looking out of the window in front of him, and Yanzi was standing in front of the car and smiled at Xu Tian. No, it wasn't a smile, it was a mockery, and the swallow seemed to be conveying something to Xu Tian.

"Hey!" Lao Chen patted Xu Tian on the shoulder. "Have you figured out the answer?"

"Huh?" Xu Tian was stunned for a moment, and when Xu Tian looked at the front of the car again, the swallow was gone. ”

"Did you figure it out?"

"Of course! This is a very clever method, and it would be a very terrible method of murder if it were used in a criminal offence. ”
