Chapter 32

The two of them still walked back according to the distance they came from. They first took a taxi to the city, and then went to the train station to pick up the ticket. The train back was a high-speed train, and the time to get on the train was almost impossible.

The moving train is much cleaner than the old train. Lu Siyu looked at the noisy environment and said to Song Wen: "Let's go to the dining car. I'll treat you to something to drink. There is a table over there, where you can write. And At this point, there should be not many people there, so it is convenient to discuss the case."

Sure enough, as he said, now is not the time for meals. Compared with ordinary carriages, the dining car is much looser and quieter. Two people occupy four seats. There is a small table in front of it. Lu Siyu gave Song Wen an order. I ordered drinks, melon seeds and snacks, and drank the water in the thermos cup by myself.

Song Wen was a little sleepy at this time. In order not to let himself fall asleep, he opened the notebook and started to draw. When the train swayed, the control of the pen tip was much more difficult than usual, but it made the drawn lines a little more focused. After a while, Song Wen drew a girl's face on the paper. It was Lin Wanwan's face. It looked indifferent and pitiful, but her eyes were unfathomable.

The number of stops the train stopped at was much less than when it came. The train was moving forward, and the scenery outside the window kept changing. It gradually moved from the town to the fertile fields, and then passed a few caves. Song Wen finished painting the portrait of the figure. Looking up, Lu Siyu sat opposite him, opened the record book, and bit his nails habitually while watching.

Song Wen found that Lu Siyu had the habit of biting his fingers when he was thinking attentively. Now he bites the fingers of his left hand in his mouth, and writes and draws on the notebook with his right hand. Song Wen looks carefully, Lu Siyu's pair is clean On his slender, well-joined hands, all the nails were bitten by him to the level of the belly of his fingers. Under Song Wen's gaze, Lu Siyu put the notebook on the table and said, "I finally figured it out, poisoning. The matter still has nothing to do with Lin Wanwan."

"What?" Hearing this sentence, Song Wen became interested and leaned forward to look. In the book, Lu Siyu drew the relationships of the characters, with Lin Wanwan as the center, the dormitory on one side and the family on the other. The family made a family tree and marked everyone they knew so far.

"Class." Lu Siyu pointed to the picture on the notebook and came to a conclusion.

Song Wen was a little puzzled, and Lu Siyu clicked on the picture again, "The class of the dormitory, and the class of her family."

Song Wen was even more confused: "There are only a few people in total, so how did you create a class?"

"Do you remember when I mentioned the gaslight effect?" Lu Siyu asked him.

Song Wen nodded.

Lu Siyu clicked the names written on the bottom of the two sides on the picture: "If in the family, the tortured and manipulated character is the mother, in the dormitory, the tortured person may be Guo Hua."

Song Wen looked at the picture drawn by Lu Siyu. It was divided into three levels. On the family side, the first level was Lin Wanwan, the second level was younger brother, stepfather, and the third level was mother.

On the other side of the dormitory, Lin Wanwan is on the first level, Dong Fang and Ma Aijing are on the second level, and Guo Hua is on the third level.

Song Wen understood a little: "What do you mean, there are classes among these people, and Lin Wanwan is the one who manipulates them?"

Song Wen still remembered that when everyone had a disagreement about whether Lin Wanwan was a suspect yesterday, Lu Siyu said that Lin Wanwan was a manipulative personality. He has read some psychology courses and knows more about controlling personalities than others. Many people with controlling personalities are not always strong, arrogant, impulsive, but may also be innocent, innocent, or even Humble, but their hearts are arrogant, paranoid, and even suspicious. For such people, their innocent appearance is their disguise, and they cleverly hide their intentions under friendly friendship, like wolves in sheep's clothing in a crowd.
