In the middle of the night, Xu Tian lay on the bed and couldn't figure it out, these things that happened in these days made Xu Tian think a lot, and after Xu Tian's inference, Lao Chen and they must have intentionally contacted Sitong.

Buzzing......

The phone rang suddenly, startling Xu Tian, Xu Tian didn't plan to answer the phone, but the person who called was Lao Chen, Xu Tian had to slide the answer button with a lazy finger.

"Officer Chen, is there any progress in the case?" Xu Tian said.

"Xu Tian, can you come out for a while? I'm right outside your door. Lao Chen said in a low voice.

"Say it on the phone! I'm a little inconvenient, Sitong is scared at home, I don't want to go out. ”

"Oh well! But be careful, I guess you've figured it out, right? ”

"Don't you ......," Xu Tian sat down, got out of bed, and stood by the window.

"Yes."

Suddenly, Lao Chen's face appeared outside the window, and Xu Tian was so shocked that he almost dropped the phone on the ground.

"Officer Chen......" Xu Tian hurriedly opened the window.

"I still think it's better to tell you in person, today I went to Yi Shuai's house to investigate." Lao Chen stood outside the window and said.

"How did it turn out?"

"It has nothing to do with Yi Shuai's case, it's just that a mentally abnormal neighbor reported a fake case." Lao Chen lowered his head and pondered for a moment. "It can't be said that it is a false case, that is, the neighbor Aunt Wang claimed to have heard the crying from Yi Shuai's house."

"Have a mentally ill neighbor?"

"That's right! When I just started talking to Aunt Wang, she said that she saw the kitchen of Yi Shuai's house turn on the light, and at that time I felt that something was wrong, because after we checked the scene at Yi Shuai's house, we asked the property to turn off the electricity of Yi Shuai's house, which was the electric switch pulled out in the meter box, and then the Aunt Wang's speech was full of loopholes, and she also claimed that her wife was sleeping in the room, snoring or something, but their home was unusually quiet. ”

"I understand, everything was reported by Aunt Wang because of mental abnormality, right?"

"Yes, I have contacted the property and the street office, Aunt Wang does have a little mental illness, but I feel that this Aunt Wang still knows a little bit of the truth, I just went upstairs and found that Aunt Wang's house was wide open. After I entered the house, Aunt Wang kept saying that she was afraid, and it stands to reason that if Aunt Wang was afraid, why did she leave the door wide open? This is completely inconsistent with the psychology of fear of people. ”

"Aunt Wang is deliberately hiding something, right?"

"Your guess is right, I found out afterwards that Aunt Wang was deliberately covering up the door of the room without couplets."

"I understand, there is indeed a custom of not posting couplets when a relative dies in the family, why should Aunt Wang do this?"

"I consulted Dr. Lin just now, and the answer she gave me was that maybe Aunt Wang missed her deceased wife very much and didn't want others to know that her wife had passed away, so she made that kind of move."

"And what do you mean by saying these things to me?"

"Haven't you found out yet? Sitong's anomaly. ”

"Sitong? What do you think is unusual about Sitong? ”

"I know, Sitong told you that I heard a woman's cry."

"You...... Are you listening to me? ”

"I'm sorry, I installed a bugging device the last time you let me sneak into your house, but I wasn't the one who was listening on you."

Xu Tian suddenly closed the window and closed the curtains.

Xu Tian...... You come out and we'll talk. Lao Chen shouted outside.

At this time, Xu Tian's thoughts were very confused, in fact, Xu Tian had already noticed that something was wrong with Sitong when he was in the cat mansion, when Sitong said that he saw a huge cat staring at the room on the window. At that time, Xu Tian felt strange, because Sitong said this, Xu Tian also deliberately followed this clue, but in the end, Xu Tian did not connect this clue with the case.

And the first time Dr. Lin came to the office, when Dr. Lin and Lao Chen told Xu Tian that Xu Tian was a test, but was that really the case? No matter how you imagine what Dr. Lin said at that time, it felt a little too simplistic, was that really a test for yourself?

Teacher Jin was hospitalized next door to Sitong's ward, as well as Lao Chen's words just now, plus Sitong's actions and words tonight.

"No...... No way! Xu Tian squatted by the window and struggled in pain, but everything was already obvious, Dr. Lin was not testing Xu Tian himself at all, but kept approaching Sitong.

Buzzing......

Lao Chen called, but Xu Tian didn't want to answer at all, after hanging up the phone, Lao Chen called again, Xu Tian couldn't care about the phone, got up and staggered out of the bedroom, and walked towards Siyan's room.

Xu Tian turned on Siyan's computer, and sure enough, the surveillance that Xu Tian asked Siyan to dismantle before was not removed, but was replaced.

Before turning on the backup of those surveillance videos on the computer, Xu Tian had basically expected what he would see.

Do you want to click on it? Xu Tian struggled in his heart.

As long as you click on these videos, all the good times will be shattered in an instant, and at this moment, Xu Tian seems to remember a lot of things.

Including the envelope with catnip that he found on his desk after returning from a tourist attraction in the north before, Xu Tian still thinks that Fang Lu found an opportunity to put it, but did Fang Lu have time to do that kind of thing when he came to the office?

Xu Tian knew this answer very well in his heart, and he should have thought of it at that time, the truth should be very simple, and only Sitong returned to the office in advance.

"Xu Tian......" Sitong walked in from the living room.

"Sitong, tell me, it's not true, right? What the hell are you doing with me? ”

"What's wrong with you? It's been very weird when I went home before, is there something uncomfortable? ”

"Don't do that, okay?" Xu Tian suddenly grabbed Sitong's wrist. "Sitong, I've always trusted you."

"What's wrong with me? What are you doing so fiercely? Sitong's eyes moistened.

Xu Tian relented again, all this should not be Sitong's fault, Xu Tian himself understands this, but what makes Xu Tian unacceptable is Sitong's condition.

Knock knock knock...... Knock knock knock......

The knocking was very loud, and it was obvious from the sound that there was more than one person knocking on the door.

"Someone is coming, I'm going to open the door." Sitong's eyes were blank, wanting to get rid of Xu Tian.

"No, you can't open the door!" Xu Tian yelled.

There was the sound of twisting the key at the door, and the moment Si Yan stepped into the office, Xu Tian felt that the whole world had collapsed.

It was not only Siyan who came in, but also Lao Chen, Dr. Lin, and Li Zhitong.

"What are you here for? Do you want to take Sitong with you? Xu Tian said.

"It's time for a real showdown with you." Siyan stared at Xu Tian and said.
