After Li Dongting confirmed that Chen Qidi had stopped breathing, he first took out the white gauze gloves prepared in advance from his pocket, and carefully wiped all the places that his hands had touched, mainly the sliding door of the bathroom, the door of the bathroom, the door of the large closet and the security door. The first thing to wipe is the sliding door of the bathroom and the door of the bathroom; The second step is to take out the handbag containing 260,000 yuan in the large closet, close the kitchen door, carefully wipe the doorknob with white gauze gloves, and then put the handbag at the door (the door of the first door); The third step was to take a mop from the bathroom (the mop was prepared by Li Dongting after killing Mr. Liu, after he put half a tank of water in the bathtub, he wet the mop, wrung it out, and put it in the corner of the first door of the bathroom), and put it on the security door; The fourth step is to change into your own leather shoes (the author has already explained before, when Li Dongting entered the door, Mr. Liu prepared a pair of cotton slippers, which was in Li Dongting's arms); The fifth step is to use a mop to drag the place where you go (you only need to mop about a square area at the door.) Li Dongting always wore the cotton slippers prepared for him by Mr. Liu during the crime); The sixth step is to carry the handbag on your back, put on the raincoat (when entering the door, Li Dongting hung the raincoat on the hook behind the security door), button the raincoat, put on the hat of the raincoat (and press the brim very low); The seventh step is to open the cat's eye and look into the corridor, on the premise of making sure that the gate of No. 204 is closed and there is no one in the corridor, Li Dongting opened the door with his hand through the raincoat, quickly flashed out the security door, gently closed the security door through the raincoat with his hand, and then quickly walked down the stairs.

Li Dongting left the scene of the murder very smoothly, except for meeting Shi Wenjie and Duan Dawei on the corridor of the second unit of the fifth building and the first unit of the eighth building, he did not meet other acquaintances, even if he met acquaintances, he was not worried, because he was wearing a raincoat, the brim of the raincoat was very low, and everyone he met on the road was all wearing umbrellas and walking in a hurry.

When he met Shi Wenjie, Li Dongting was not worried at all, in his opinion, Shi Wenjie was just a child, and an underage child would not pay attention to a person who passed by him.

Li Dongting's confidence was reasonable, Shi Wenjie really didn't recognize him, but he never dreamed that the problem was the scotch tape on the back of his raincoat. This can be regarded as providence!

"Aren't you nervous when you see Duan Dawei?"

"Although Duan Dawei and I live in the same unit, we never talk to Duan Dawei. Actually, if I go my own way as usual, I guarantee that there is nothing at all, as the old saying goes, be a thief with a weak heart, when I saw Duan Dawei walking in front, I subconsciously slowed down, and after Duan Dawei entered the door, I was worried that I would meet other people again, so I sped up, and I didn't expect Duan Dawei to feel abnormal. ”

"The French Open is magnificent, negligent but not leaky, if you don't show flaws in Shi Wenjie and Duan Dawei, you will also show flaws in other places."

After Li Dongting sent his handbag home, he took an umbrella and climbed over the wall into the school, and he didn't do anything in the school's computer room, he stood in the window of the computer room and heard the noisy sound coming from the community, and saw people rushing to the scene of the crime.
