Chapter 9

　　Lin Yuan followed Xu Yang's gaze and saw the sleeping pills on the dressing table. However, she didn't care about what Sijia was eating, was it

　　Lin Yuan shook her head in disbelief and Xu Yang asked, "Who is the person who came with you?"

　　Lin Yuan still said, "No one, I came alone."

　　"So where are the photos?" Xu Yang pressed forward step by step, "No photos, no jade hairpins. Are you talking nonsense? What is your purpose, to interfere with the police's investigation?"

　　"No, no," Lin Yuan denied in a low voice. She fell back and sat on the bed. Suddenly, the wall behind the dressing table made a sound. Xu Yang walked over in surprise and moved away from the dressing table. Behind it was a secret door, and the dark passage led somewhere.

　　Xu Yang walked in, followed by Lin Yuan. At the end of the passage was another door. Xu Yang pulled hard, but the door remained motionless. The two of them retreated to the Yu Si family. Xu Yang said, "So, that's how you entered the house."

　　Lin Yuan didn't understand yet. Xu Yang took her downstairs and said, "Think about it. Did you enter this building last time you came?"

　　Lin Yuan felt a bit blurry as she said, "The back of the photo shows Unit 7, so I should have entered Unit 7."

　　After speaking, Lin Yuan looked at the sign and saw that it was indeed the number 7.

　　Xu Yang explained, "The order of unit buildings here is as follows: the first row is from left to right, with units one, two, three, and four in sequence. The second row is reversed, with units eight, seven, six, and five from left to right. What you think of as unit seven is actually unit six, and there is a passage between unit six and unit seven. That is to say, you enter unit six's 402, and when you fall asleep, you are moved from the passage to unit seven's 402."

　　"Why, why?" Lin Yuan felt incredulous.

　　"In order for me to see you."

　　"But I remember when I entered the building, there was a sign that read '7'," Lin Yuan recalled.

　　"It's this number that makes you ignore everything else. You only pay attention to the building number of the unit you entered, rather than the number of buildings in this row. Can you remember how many buildings you walked through before going up?" Xu Yang said, taking off the sign, which was hanging and not nailed down.

　　Lin Yuan shook her head and said, "I didn't pay attention, but I know there is a 'chalk outline' of a corpse in front of the building door."

　　Xu Yang said, "I still find it strange that Yu Si lives in Unit 7. How could he fall off the roof of Unit 6? It seems that this conspiracy is not simple."

　　The two of them walked towards Unit 6, intending to explore the truth.

　　Xu Yang knocked on the door of 402, and the person who opened it was actually Yu Qing. Xu Yang said suspiciously, "Aren't you staying at a hotel?"

　　Yu Qing and Yu Si have very similar appearances, except that Yu Si has straight black hair, while Yu Qing's hair is dyed brown.

　　Yu Qing said, "Staying in a hotel every day is too expensive."

　　"Is that right?" Xu Yang sneered, "Is this rented or bought?"

　　Yu Qing exclaimed in surprise, "This is my sister's house. How could I possibly rent or buy a house again?"

　　Lin Yuan and Xu Yang exchanged a glance. If Yu Qing was not pretending, then she, like Lin Yuan, had been guided into the wrong room.

　　But what is the purpose of that guide?

　　Xu Yang said calmly, "There are still some doubts about Yu Si's death. I need to double check."

　　Yu Qing exclaimed "Oh" and said, "You can check at will."

　　Xu Yang looked around and found that the layout here was exactly the same as that of Room 402 in Unit 7, ranging from large furniture to small dishes. Without prior knowledge, it was impossible to distinguish them.

　　Entering the bedroom, the same bed, the same dressing table, the same jewelry, and even the placement of sleeping pills were the same. Xu Yang approached the bed, groping for the trigger mechanism, but never succeeded. Is the way he opened the secret door different from the one in Unit 7?

　　Lin Yuan walked up to the dressing table and looked at the pile of jewelry, not noticing anything unusual. When she looked up, she actually saw Yu Si in the mirror.

　　Lin Yuan suddenly turned around, but behind him stood Yu Qing.

　　"What's wrong?" Yu Qing asked as she approached Lin Yuan. Lin Yuan smelled a fragrance that reminded her of Yuan Yu. She took a step back and touched the edge of the dressing table, making a sound behind her. Lin Yuan turned around and saw the hidden door behind the mirror.

　　Xu Yang also walked over upon hearing the sound. He moved away from the dressing table and, as soon as he opened the secret door, both of them called out at the same time

　　Lin Yuan woke up, realizing that she had a dream of investigating with the police, but was startled to wake up. In the secret door, Lin Yuan saw her brother, staring at her own brother.

　　He had a dagger inserted in his chest, and the blood flowing out had dried up and turned black.

　　Lin Yuan dared not think anymore, but her body trembled uncontrollably. The alarm clock showed it was 3 am, and she couldn't help but call her brother.

　　The music played for a while and the phone was connected.

　　"Hello?" was a woman's voice, which Lin Yuan felt somewhat familiar with. Thinking back, it seemed like Ye Mei's voice, but it sounded a bit off.

　　The other party didn't respond, so they hung up the phone. Lin Yuan looked at the dialed number, yes, it was his brother's number. Ling Chen at three o'clock, was it Ye Mei by his brother's side?

　　Xu Yang sat up in shock. It had been over three years, and this was the first time he had dreamt of Xiaoxuan. What he saw was her body.

　　Her eyes are open, her face is filled with fear, and a sharp knife is inserted into her heart

　　Xu Yang didn't want to think back and took out his necklace, staring blankly.

　　Three years ago, Xu Yang was handling a case in another city. One night, Xiao Xuan called, but Xu Yang was on a mission and didn't answer. When he tried to call back after the mission was over, it showed that it was turned off. He thought Xiao Xuan had already gone to sleep, but it wasn't until the case was over that Xu Yang found out that Xiao Xuan had gone missing.

　　At Xiaoxuan's house, Xu Yang found a note in Xiaoxuan's handwriting, which read: "At 3 am, I woke up from my sleep and couldn't remember my dream clearly. When I turned off the lights to continue sleeping, I felt a pair of eyes staring at me. I was so scared. Xu Yang, why haven't you answered the phone yet..."

　　For over three years, Xu Yang never stopped searching for Xiao Xuan, but he never heard from her. How could he have such a dream today?

　　Lin Yuan and Xu Yang arrived at the old dormitory of the Postal Bureau coincidentally. They all wanted to know if Room 402 in Units 6 and 7 was really connected.

　　The person who opened the door was not Yu Qing as imagined, it was just an ordinary resident, and the decoration in the room was completely different from that of Unit 402 in Unit 7.

　　The two of them left Unit 6 and arrived at Yu Si's home again. There was no hood on the bed, and the wall behind the dressing table was also intact.
