The next day (Sunday, May 7)

Ten o'clock in the morning

Master Chen and a few of his colleagues are in full swing to scrape putty powder for this renovated house, laying the foundation for the next step of painting the wall paint. Suddenly, the door of the opposite house opened. A young man came over and greeted them politely, and asked, "I have some ink splashed on the wall of my house, can a few masters come and help brush it?" There aren't many splashes and won't take up much of your time. ”

Hearing that he wanted to help, Master Chen snorted coldly in his heart. It's not easy for them to work these years, the average working time is more than ten hours, and there is no rest time, where are they willing to help others do things for no reason.

But in the next second, the young man walked in, took out a few bills with a face value of 100 yuan, and gave one to each of the three construction masters.

Master Chen immediately decided to take advantage of the absence of the head of the household and secretly go to earn extra money.

"Hey! You're welcome! Master Chen said as he accepted the money.

"It's not easy for everyone, and it's right to give some money." The young man said, and then took Master Chen into his house, pointing to the wall at the corner of the living room and kitchen, where there was a dark green ink, "This is it, I'm sorry for you." ”

Master Chen thought it was a painted wall, but it was a bit troublesome to deal with. This kind of wall can be solved in two or three strokes just after scraping the putty powder, and it can also ensure that there are no traces of new brushes.

Of course, Master Chen just thought about it in his heart and didn't say it. This young man didn't understand these things at first glance, and he really made a lot of money by giving them a hundred for such a simple matter.

"Okay, it's not hard to deal with." Master Chen went back to get the brush.

The young man followed and asked, "Master, is it easy for people to see after we finish painting this wall?" ”

"Don't worry, you won't see any difference when you're done." Master Chen waved his hand to reassure the young man, then picked up the brush and returned the same way with a small bucket of putty powder.

The young man found a few pieces of paper to put on the ground, and Master Chen put the brush into the bucket and turned around, then lifted it a little, paused for about ten seconds, and directly began to paint the inked wall.

After a few brushes, the walls turned white again, but the color of the new brushes was still a little different from the other places.

"Okay, that's it, and when it's done, you won't see any difference." Master Chen said.

"Thank you." The young man thanked.

"It's all a small problem, so I'll go over and work if it's nothing." Master Chen smiled.

The young man helped Master Chen lift the bucket of putty powder: "Okay, don't waste your time, I'll help you carry it back." ”

"Oh, no, no, just a few steps to ......" said the young man who had already helped Master Chen move the bucket back, and Master Chen smiled and felt that this young man was quite sensible.

The young man finished carrying the bucket and thanked him again before returning home. Master Chan and his two co-workers smiled at each other, happy with the extra money they had easily earned today, and then continued their work.

……

Closing the security door, Zhang Yichi, who was still smiling just now, regained his composure. He walked over to the blood-spattered wall and took a closer look at the freshly painted surface.

After feeling that there was basically no problem, he sat back on the sofa, closed his eyes and rubbed the bridge of his nose, and pondered something.

……

It was past eleven forty that night.

Zhang Yichi went back to the basement again, took Lu Tao's schoolbag, glasses, and shoes home, knocked off the lenses of Lu Tao's high-count glasses, and brushed the shoes with blood stains again, and then changed into his school uniform and put on the glasses that had been knocked off the lenses.

Lu Tao's shoe size was a little smaller than his, and he took out the insoles inside, so that he was barely too crowded to put them on.

He stood in the bathroom, looked at himself in the mirror, felt a little dissatisfied, and found a cap strap again.

Glancing at the time, it was already eleven fifty, Zhang Yichi returned to the bedroom and pulled out a pair of black trousers and a shirt with a hood from the closet.

Putting these two clothes, a pair of shoes, and a bag into his schoolbag, Zhang Yichi did one last thing, that is, he turned off Lu Tao's mobile phone now and pulled out his mobile phone card.

The minutes ticked by, and it approached twelve o'clock. Zhang Yichi didn't take Lu Tao's mobile phone, but just changed into Lu Tao's schoolbag, shoes, and glasses and went out.

As he went downstairs, he took deep breaths from time to time to adjust his state and try to look normal.

Out of the unit door, Zhang Yichi was exposed to the camera. He bowed his head slightly, the brim of his cap large enough to cover his face. He began to follow the route he had taken yesterday, going out from the main gate of the community, boarding the overpass, bypassing the square, passing by the main gate of the Yonghe community, and entering the grove next to the Yonghe community.

Entering the grove, Zhang Yichi first looked around vigilantly and quietly, and after making sure that there was no one, he immediately took off his cap, opened his schoolbag, took out his civilian clothes and changed into them, and stuffed his school uniform, cap, Lu Tao's shoes and glasses into the bag.

Pulling up the hood of his shirt to cover his head, Zhang Yichi held the bag containing the school uniform in one hand and Lu Tao's schoolbag that was already empty in the other, and continued to walk through the grove, looking at the road outside from the grove.

It took some time to finally find a blind spot in the surveillance, Zhang Yichi walked out and threw the schoolbag into the trash. The trash cans should be cleaned once a day, and the bags will be taken away from this dangerous area without leaving a trace.

Zhang Yichi, who has been refreshed, walks briskly on the sidewalk next to the highway, throwing things in the garbage cans on the side of the road from time to time. deliberately made a big circle, and when he returned to the community from another gate, Lu Tao's schoolbag, shoes, glasses, and cap had all been thrown away.

When he came to the front of the No. 17 residential building, Zhang Yichi did not enter the fourth unit and went home directly, but entered the first unit.

After entering a unit, Zhang Yichi breathed a sigh of relief. When he is not monitored by the camera, his insecurity will be weakened a little.

Taking out the key, Zhang Yichi opened the door of the basement, walked in and locked the door. Then from the narrow hallway of the basement to the staircase that leads to the four-unit hallway.

When he came out, he made sure that he had left nothing to miss, and then strode up to the sixth floor and returned home.

"Whew!" With a long sigh of relief, Zhang Yichi felt a little relieved. He set aside the bag containing his school uniform and collapsed himself on the couch.

After lying down for a long time, Zhang Yichi sat up again, leaned over and picked up a notebook from the coffee table, most of his time during the day today was spent predicting what would happen next, and recording various confessions and new wording in the notebook.

The lights weren't on, he didn't open his notebook, he just held it and lay down slowly, closed his eyes, and waited quietly for the dawn to come.
