This result once again strengthened the persuasiveness of the bold idea in Li Xiangnian's heart that he did not dare to say easily.

The excitement passed quickly, and Li Xiangnian's face was instantly covered with a layer of haze, because the final result of this clue was not what he nor Lu Tao's mother wanted to see. Recording the surveillance, he returned to the car without saying a word. It was noon, and the sidewalk was full of students walking together, and he stared through the car window for a long time, a little distracted.

The backs and smiles are the daughters who were close to him many years ago, Lu Tao who is moving forward in silence, and Zhang Yichi, who is still unpredictable.

"Ahem!" Li Xiangnian's face changed, and he coughed violently. He clutched his chest to suppress the discomfort as he reached out and fumbled for the medicine bottle.

To him, it's like he's struggling in an hourglass right now. When the sand runs out and swallows him up, when it will be his death. The scary thing was that he could already see with the naked eye that the sand above his head was running out.

——

In the afternoon, Li Xiangnian simulated the whole process in person according to the assumption that he couldn't let go. Coming out of a certain unit of a building, all the way to the vicinity of Yonghe Community, entering the grove to change clothes, and then avoiding the monitoring detour back to the community, entering another unit of the same building, and returning to the original location through the basement.

It's another attempt to know the answer but still choose to do it. There was still no direct evidence to prove that things were really what he had guessed, but the information he had now was enough to perfectly deduce his assumptions.

Now there is no other direction, and it seems that there is only this one ending left for Li Xiangnian.

He wants to try to find some eyewitnesses to restore the course of the incident, the cause and effect.

"Knock knock." He knocked on the door of the resident opposite Zhang Yichi's house. It's already past three o'clock, and Zhang Yichi has already gone to class, so he doesn't have to worry about startling the snake.

The door opened, and a man poked out: "Is there something?" ”

The man looked a little guarded, and Li Xiangnian took out his police officer card to show the other party. The man suddenly relaxed, but he was also puzzled why the police would find him: "You come in and sit, come in and sit, I didn't break the law, you are ......"

"Don't be nervous." Li Xiangnian just walked in and stood at the door and closed the door, without taking a step further, "I just asked you something." ”

"Oh...... You say. ”

"The other day—just last weekend, was there anything unusual about your family?" Li Xiangnian asked.

The man smiled: "I wasn't here last weekend, you also saw it, this house is still being renovated, only the renovation workers were there last weekend." Speaking of which, you're just in a hurry, I'm here today to check if there's anything to cut corners. At a different time, you specify a no-beat. ”

"Ah...... So you mean, last weekend renovation workers were there? Li Xiangnian did not give up easily, and clung to this clue to investigate deeply.

"Yes." "They must have been busy painting the walls last weekend," the man recalled. ”

"You should still have their contact information, right?"

"You're looking for them?"

"Hmm."

"Okay, I have a mobile phone number here, you can remember ......"

After getting the mobile phone number, Li Xiangnian quickly dialed it and learned that the decoration team was now carrying out renovation work in another building in this community, Li Xiangnian did not waste time and rushed to it immediately.

After arriving at the renovation site where the renovation team was located, Li Xiangnian met three workers who had been working across from Mr. Zhang's home last weekend.

After learning that the person who came was a criminal policeman, these workers told the whole story of last weekend. Li Xiangnian was quite surprised, he didn't expect that these workers had really come into contact with Zhang Yichi, but he didn't have much expectations.

After some conversation, Li Xiangnian learned about what happened last Sunday. Last Sunday, Mr. Zhang gave the renovation workers money to help paint the walls of their home. The time of brushing the wall basically coincides with the time of Lu Tao's disappearance, which makes Li Xiangnian, who has roughly guessed the true face of the case, have to wonder if there is any connection.

Li Xiangnian asked the renovation workers to carefully recall whether there was anything suspicious during this period, and the worker in charge of painting the wall mentioned a point after some recollections, that is, when Zhang Yichi asked the decoration workers, he said that the wall at home was splashed with ink, but it is difficult to imagine how the wall at the corner of the living room and kitchen was splashed with ink. The most important thing is that the ink is not like a splash, but more like a smear.

In the afternoon of the same day, Li Xiangnian found the courier who had delivered the courier to Zhang Yichi last Saturday night, and he also had a lot of gains. According to the courier, he was still quite impressed by the events of that day, because he went to Zhang Yichi's house and knocked on the door for a long time, and no one came out for a long time, and when he went downstairs to leave, Zhang Yichi suddenly gave him a call back, saying that he had just fallen asleep and did not hear the phone ringing, and took the initiative to go downstairs to pick up the express.

On that unknown weekend, the renovation worker and courier were people who had direct contact with Zhang Yichi. Each of them recalled that during their contact with Zhang Yichi, they found some unusual places, which might not be too much of a problem if they were just taken out and looked at, but if they were incorporated into Li Xiangnian's speculation, the terrible truth would emerge little by little.

casually found a noodle restaurant, Li Xiangnian ate a bowl of noodles and returned to the car. After taking the medicine, he glanced at the time, and it was just over six. Today is Friday, and students leave school much earlier in the afternoon.

After thinking about it carefully, he drove to the downstairs of Zhang Yichi's house, and didn't wait long to meet Zhang Yichi who was coming home from school. Zhang Yichi also recognized that this was Li Xiangnian's car, and did not pretend to ignore it, and walked straight forward.

"Get in the car." Li Xiangnian rolled down the window and said.

Zhang Yichi paused, didn't ask anything, opened the car door and sat in the passenger seat.

"Have you eaten? Shall I take you to eat something first? Li Xiangnian held the steering wheel in his hand and looked ahead.

Zhang Yichi fastened his seat belt: "I ate in the school cafeteria." ”

"Good. Weekend off, right, I'll take you for a drive. Li Xiangnian said and started the car.

"What do you think about this today? Aren't you going to find Lu Tao? Zhang Yichi glanced at Li Xiangnian, who looked ahead intently.

"Found it." Li Xiangnian replied.

Zhang Yichi's eyes flickered, and after a few seconds, he turned his head sideways: "...... Where is it? ”

"You should know, right?" Li Xiangnian still didn't look at Zhang Yichi, drove out of the community, and drove on the busy avenue.

"Me? I don't know? Zhang Yichi smiled.

"Actually, we all know that." Li Xiangnian's face was expressionless, the neon lights outside shone on him, and his eyes were still dim.
