Li Xiangnian glanced at the hand-drawn map and began to take Zhang Yichi's house as a starting point and follow Lu Tao's escape route to Yonghe Community.

At the same time, Zhang Yichi was covered in cold sweat and stood by the window watching Li Xiangnian leave. Then I took the key to the basement, went out of the house, and went straight to the basement.

He hurried down the stairs and panted to open the basement room where Lu Tao's body was hidden.

It has been nearly six days since Lu Tao's death, and the body has begun to swell, with bloody foam flowing from his mouth and nose.

Zhang Yichi picked up Lu Tao, who was weak, and a corpse smell suddenly hit his face. He tensed up, his face was pale, he gritted his teeth and was silent, and began to carry Lu Tao out of the basement.

——

Li Xiangnian walked out of the main gate of the community, crossed the overpass, and arrived all the way to Yonghe Community. Here he stopped, observed the surrounding monitoring probes, and began to deliberately avoid the monitoring and walked towards the grove next to the Yonghe community.

After entering the grove, Li Xiangnian calmly looked around. After a long time, he came out of the grove, put his hands in his pockets, and looked at the sidewalk to the left and right. Whether that person is the real Lu Tao or the pretended Lu Tao, it is impossible for him to disappear in the grove for no reason, he must have come out of here, but it is not clear from which direction he left.

If this person is Zhang Yichi, then he is bound to return home.

The surveillance late last Sunday night also hid a mystery.

——

Carrying Lu Tao back home, Zhang Yichi opened the refrigerator, removed all the partitions, made enough space, and stuffed Lu Tao in.

Sitting back on the couch, sweat already soaking his clothes.

The plastic wrap blocked the emitting of the corpse smell to a great extent, but Zhang Yichi was very close to him when he was carrying Lu Tao, and he was inevitably smoked all the way. The smell of corpses was a physical and psychological smell that was almost close to the limits of human tolerance, and he thought back to the experience he had just experienced for a moment, and his stomach twitched violently.

Dinner was all spewed up.

After vomiting, he knelt in front of the toilet, exhausted.

——

Li Xiangnian originally wanted to take advantage of the victory to pursue, so he went to investigate the surveillance that night. However, his body collapsed again, so he had to arrange the plan to be done tomorrow.

He came home and lay on the bed tossing and turning, the case, his daughter, the sick ......

——

Friday, May 12.

Zhang Yichi got up in the morning and went to school.

Li Xiangnian arrived at the property in his community at half past seven and called up the surveillance in front of the residential building where Zhang Yichi was located on the night of May 7. The time starts at 11:50 p.m. on May 7 and ends at 7 a.m. the next day.

After the double-speed playback, Li Xiangnian did not gain anything. Because from 11:56 a.m. on 7 May, when 'Lu Tao' went out, to 6:50 a.m. on 8 May, when Zhang Yichi came out to school, apart from these two times, no other suspicious person had entered or left.

Could it be that your guess was wrong? There was a train of thought that was blocked, and Li Xiangnian questioned his guess.

Eventually, he decided to put the issue aside for now.

"Do you have the basement key for every residential building in your community?" Li Xiangnian asked the property manager.

"yes." The pot-bellied property manager who accompanied Li Xiangnian to see the surveillance replied, "Each resident has two keys. One opens the door to the basement, and the other opens the door to each resident's private storage room. ”

Li Xiangnian pondered for a moment: "Can I trouble you to go with me to the basement of Unit 4 of Building 11?" ”

"Okay." The property manager readily agreed, "Let me go and get the keys." ”

After the property manager found the key, the two came to the corridor of the unit where Zhang Yichi lived. The property manager opened the basement door, reached out to turn on the light, pointed down, and said, "This is the basement." ”

Li Xiangnian stepped down the steps, and the property manager followed him.

When you reach the bottom, you will be greeted by a long and narrow corridor lined with security doors on both sides of the corridor. Li Xiangnian turned to look at the property manager: "Are these the storage rooms allocated to each resident?" ”

"Storage rooms are not allocated and need to be purchased additionally by residents."

"Can you open the storage room of the residents of Unit 5 and Room 602?" Li Xiangnian asked again.

"The household didn't buy a storage room." The property manager checked the information book, "And even if we had, we wouldn't be able to open it." Because the key to the storage room is only owned by the resident, we have no right to open it. ”

"Ah......" Li Xiangnian put his hands behind his back and walked deeper into the corridor.

He hadn't gone far before he stopped and looked to the side, where another staircase appeared that stretched upwards: "What's going on?" ”

The property manager rushed over and took a look and said, "This is the basement door of the third unit. ”

"What...... What do you mean? Li Xiangnian was very puzzled, "This basement is shared by the whole building?" Isn't it used separately by each unit? ”

"The basement on our side is a whole, and the six units in each building are shared, so there are six entrances and exits in the basement." The property manager explained, "There used to be bears who came in and played hide-and-seek, coming in from one unit and going out from another. It was also because I was afraid that something would happen to the child, so the basement door was locked. ”

"Wait." Li Xiangnian heard an important piece of information, "You mean, if you come in one unit, you can also come out of the sixth unit, right?" …… Is the lock in the basement of each unit the same? ”

The property manager said: "Yes, all six units go into the same basement, and there is no point in setting different locks." ”

Li Xiangnian's eyes narrowed, and something quickly passed in his mind.

"Let's get out."

——

Li Xiangnian's previous assumption was that the person who came out of Unit 4 on the night of May 7 was not the real Lu Tao, but Zhang Yichi pretending.

However, the evidence was not sufficient, so he went to the surveillance and tried to find evidence that Zhang Yichi came back in the early morning.

Unfortunately not.

This made him think that his guess was wrong. But now the appearance of the basement makes his hypothesis valid again. What if Zhang Yichi, in order to hide people's eyes, came out of the fourth unit disguised as Lu Tao and entered from other units?

He began a thorough investigation of all those who had entered the six units of Building 11 between 11:56 a.m. on May 7 and 6:50 a.m. on May 8.

Because this time is basically early in the morning, there are few people, and the investigation is very fast.

In the end, three suspicious persons were demarcated, one entered the first unit, one entered the fifth unit, and one entered the sixth unit.

After taking pictures of the three people's clothing, Li Xiangnian went to monitor the sidewalk outside the grove near the Yonghe community. If one of these three people appears in the corresponding time period of the monitoring here, then it means that Li Xiangnian's assumption is correct.

After a close investigation, a result that made Li Xiangnian so excited that he was about to scream came out.

During the fatal time period from 11:56 a.m. on May 7 to 6:50 a.m. on May 8, a man wearing a sweatshirt, a hood, and a bag appeared on the sidewalk outside the first unit of Zhang Yichi's residential building and the grove near the Yonghe community!
