When Gu Qiao woke up the next day, he found himself lying in Tan Yuhe's bedroom. He scratched his head. Did he remember that he fell asleep on the sofa last night?

Putting on the slippers, he went to the bathroom to take a shower, washed himself by the way, tidied himself up, and then came to the living room.

He was sitting on the sofa in the living room, looking at Tan Yuhe's busy figure in the kitchen, everything seemed so comfortable, except of course that the unfinished case was a bit sad.

While Gu Qiao was thinking, Tan Yuhe took the freshly prepared food and put it on the table in the living room, calling him to eat.

"What time did you go to class today? I forgot." Gu Qiao asked Tan Yuhe holding a slice of bread with a bite in one hand and a glass of milk in the other.

Tan Yuhe raised his hand and looked at his watch: "9 o'clock, it's 8:30 now, there is still half an hour."

Gu Qiao: "I'll see you off. I just happened to be researching the shadow of the girl in red."

Seeing Tan Yuhe nodding, he immediately speeded up his eating. In less than 5 minutes, he put down his chopsticks and watched Tan Yuhe eat.

"By the way, why was I in your bedroom this morning? Where did you sleep?" Gu Qiao seemed to have just remembered that he woke up in Tan Yuhe's bedroom this morning.

Tan Yuhe paused holding his hand holding the milk: "I carried you there. Isn't the air conditioner in the second bedroom broken? I was afraid that you would be too hot to sleep at night, so I made do with the night on the sofa. I already called you this morning. Get someone to fix the air conditioner, and it should be fixed when we come back tonight."

If Gu Qiao knew that he was carried back to the bedroom by the princess last night, the man would probably fight him desperately.

"Ah, I'm so sorry that I let you, the master, sleep on the sofa all night." Gu Qiao rubbed her nose, her tone a little embarrassed.

"Don't be embarrassed, send me to Rongcheng University today, just make amends." Tan Yuhe put down the cup, stood up, picked up the coat hanging on the stool, and was about to go out. Gu Qiao followed behind with the car keys back.

After arriving at Rongcheng University, Tan Yuhe was almost late, and the two parted ways at the school gate. Tan Yuhe went to the classroom, and Gu Qiao went to the girls' dormitory.

During class time, there were not many people in the girls' dormitory. In addition, the aunt who guarded the gate had a deep impression on Gu Qiao, knowing that he was a policeman, so she let him in directly.

Gu Qiao followed the house number to find Wang Huiyan's dormitory, and opened the door with a slight push. After entering, he found that the room was still the same as they left before.

He walked to the place where the girl in red appeared that day, and looked around. He could see everything in the dormitory at a glance, and there was nothing suspicious at all. He sat on the chair in front of the desk with some disappointment, thinking about waiting for Tan Yuhe to finish teaching. Tell him to come and have a look.

Not long after, his cell phone rang. When he lowered his head to pick up the cell phone, something on the opposite side suddenly blinked his eyes. While picking up the cell phone to connect, he squinted his eyes and looked at the window on the opposite side of the building.

Tan Yuhe's voice came from the receiver: "Are you still at Rongcheng University? I know what happened to the shadow of the girl in red!"

Gu Qiao also saw clearly at this time, there was something dazzled his eyes in the opposite building, and he said to the phone: "I know too! I'm in Wang Huiyan's dormitory now, hey, you didn't go to class?"

Tan Yuhe hurriedly replied: "Don't move now, I will find you later."

After he finished speaking, he hung up the phone, and Gu Qiao also sat on the chair, looking at the things in the window facing the opposite floor and this dormitory.

After waiting for about 10 minutes, Tan Yuhe arrived, and the first thing he said when he opened the door was to ask Gu Qiao: "Do you know what happened to that shadow?"

Gu Qiao pointed to the opposite side, motioning him to look at it for himself, and when Tan Yuhe saw the black camera-like thing, he let out a soft breath: "I guessed right, it's a projector, the principle of a projector It is a convex lens imaging, so that the object presents an upside down magnified real image on the light screen!"

Hearing this, Gu Qiao asked suspiciously: "Light screen? But that girl was floating beside the bed at that time, where is the light screen?"

"No, it's not by the bed." Tan Yuhe pointed to the door of the dormitory and continued: "It's by the door! Because the door is next to the bed, we thought that the girl's hair was floating by the bed!"

Gu Qiao patted her thigh: "That's right, the door is a light screen! That means the person in the opposite building is the one who made the girl in red and hung Liu Si's body in the haunted house?"

Seeing Tan Yuhe nodding his head, he grabbed Tan Yuhe's arm and walked out: "Since we've found someone, go to the opposite building and have a look, what's the ink still here!"

When the two left the dormitory, Gu Qiao thought of a question: "Hey, shouldn't you be giving a lecture? Why did you come out?"

Tan Yuhe replied calmly: "I temporarily ended get out of class with another teacher, and my class has been changed to the afternoon."

Would he say that he was in the middle of the class, suddenly noticed the projector in the classroom, rushed out of the classroom and returned to the office for a temporary class?of course not!

After arriving at the opposite building, Tan Yuhe discovered that this was the teachers' dormitory in the school. The architectural styles of the two dormitories were almost exactly the same, because Wang Huiyan's dormitory was on the fourth floor, and the floor opposite her should also be on the fourth floor.

They found out from the uncle downstairs that there was only a female teacher named Li Mei living on the fourth floor. Looking at the photo of the teacher, Gu Qiao suddenly felt that he seemed to have seen this person before.

Looking at Tan Yuhe with a serious face next to him, he suddenly remembered that the last time Tan Yuhe sent him a message asking him to come to Rongcheng University, he also saw the female teacher chatting and laughing with Tan Yuhe.

Walking to the door of the female teacher's dormitory on the fourth floor, Tan Yuhe knocked lightly on the door, and soon the door was opened. Seeing Tan Yuhe and Gu Qiao, the person who opened the door didn't seem too surprised, she said lightly: "Professor Tan ,You came."

Tan Yuhe pursed his lips: "Why did you do this?"

"For what? I really can't figure out why you are so smart? Of course I am for Tian Tian." Li Mei hugged her shoulders and leaned against the door frame, her tone still did not fluctuate much.

"What is the relationship between you and Tian Tian?" Gu Qiao was a little puzzled: "I read your profile just now, you are 28 years old this year, if Tian Tian hadn't passed away, she is only 22 years old now, how can you have an intersection? How did you make the figure disappear suddenly in the surveillance of the haunted house?"

Hearing Gu Qiao's question, she opened the door: "You go in and take a look and you will know what we are related to."

After entering the door, the goal is a row of neat photos. The people inside are Li Mei and Tian Tian. There is a large easel in the living room, and the painting on it is also Tian Tian. I saw a delicate picture in front of the TV. The album, the cover of the album, is a kiss photo of Li Mei and Tian Tian.

Gu Qiao looked at Li Mei in surprise and asked, "Are you... a couple?"
