Gao Liang looked very depressed.

In other words, in the world of academic masters, it is unreasonable to meet Gu Chen twice in a row and be unlucky both times.

The first time I lost face, and the second time I got myself involved in a lawsuit, it was terrible no matter how you looked at it.

Therefore, it is not a loss at all for him to speak out.

But Gu Chen couldn't understand it this way.

Between Gao Liang and the thief, someone must have failed to explain correctly.

Which of the two was the last to leave Zhu Ruiping's room is a key factor in the current investigation.

Officer Wang and Li Ke still refused to give up, so they continued to ask Gao Liang and the thief for various details in order to find the so-called breakthrough.

But Gu Chen didn't dwell on it any longer.

When he entered Zhu Ruiping's apartment for the first time and was about to leave and go to the monitoring room downstairs, Gu Chen once saw a light beam flashing through the peephole of the door of the resident's room opposite.

It is certain that there was indeed someone on the opposite side at that time.

It was just that Gu Chen at that time was anxious to find the surveillance footage, so he put this matter aside for now.

Now that the two major suspects have been arrested, Gu Chen simply left the room and walked directly towards the apartment opposite.

Lu Weiwei noticed from the corner of her eye that Gu Chen had left, and hurriedly chased after him: "Junior Brother Gu, where are you going?"

"Look across the way." Gu Chen said.

"Opposite?" Lu Weiwei was a little confused. After a moment of slow reaction, she said, "Yes, why don't you ask the residents opposite, maybe they will know something."

Thinking of this, she quickly caught up with Gu Chen and together they came to the gate opposite.

“Tuk-tuk-tuk.”

Gu Chen knocked on the door opposite.

However, after knocking several times in succession, there was still no movement on the other side.

But judging from the light at the cat's eye, it seems to be inhabited.

"Is anyone at home? We are the police and we have something to disturb you." After Gu Chen called out, he started knocking on the door again.

Lu Weiwei also started to follow Gu Chen's rhythm and prepared to knock on the door together.

But just as she was following Gu Chen's rhythm, before her fist hit the door panel, she heard the door lock click and someone unscrewed it.

As the door opened a gap, a white-haired old man slowly poked half of his head out and asked weakly: "Excuse me...is there something wrong?"

Gu Chen smiled and said: "Uncle, we are the police. The household that lives opposite you had a murder tonight. Do you know about this?"

"I know." The uncle didn't shy away and said directly: "There are so many police downstairs and in the room opposite, how could they not know about it."

"Then do you know the residents opposite?" Lu Weiwei also quickly asked.

The old man hesitated for a moment, and then said calmly: "The owner's surname seems to be Zhu, and he is the major shareholder of Zhu's Tea Company. I seem to have met him several times before, but we have not interacted with each other, and he does not often live here.

"

"Very good." After learning about this situation, Gu Chen first encouraged the old man, and then asked: "Have you seen anyone coming to the other side tonight? If so, can you recognize him?"

Although Gu Chen said this, he didn't have much hope.

However, the old man said calmly: "I heard a violent movement in the opposite room before, so I went to look at the cat's eye and found a black figure rushing out from the opposite room."

Lu Weiwei's eyes widened and she quickly asked him: "Then... what happened next?"

"Then?" The old man scratched his cheek and recalled for a few seconds before adding: "Then I discovered that the person who just rushed out of the room suddenly turned around and rushed in again, and then heard a voice from the other side.

There was a loud noise and the sound of things breaking, and then the black figure rushed out again and left immediately."

Lu Weiwei was a little excited by the clues suddenly provided by the old man.

This is a key clue in the case. There are actually witnesses. Happiness cannot come too suddenly, so Lu Weiwei quickly asked him: "Uncle, have you seen that person's face clearly? If you are asked to identify it, can you?"

Do you recognize it?"

When the old man heard what Lu Weiwei said, he immediately waved his hand: "I can't see clearly. The sensor light in the corridor is broken. It's dark outside and the light is very dim. I can't see the other person's face clearly. I can only

Saw a dark shadow."

"Uncle, can you...can you think about it carefully? Maybe you can see it clearly?"

Lu Weiwei wanted to insist a little longer, but the old man's answer was still simple: "I'm sorry, comrade police, if it were you, you probably wouldn't be able to see clearly. If you don't believe me, come and take a look for yourself."

The old man was also afraid that the police would misunderstand him, so he simply opened the door and invited Lu Weiwei and Gu Chen into the house to check.

After closing the door, Lu Weiwei first observed the scene according to what the old man said.

The door to the room opposite is now open, and the light is slightly brighter. The faces of several colleagues standing at the door can be clearly seen.

Then Lu Weiwei opened the door again, ran quickly to the opposite room, and closed the door slightly.

Then she "swooshed" again, quickly returned to her previous position, and closed the door of the old man's house again.

"Sure enough, it's really dark." Lu Weiwei was a little frustrated, and then asked Gu Chen: "Junior Brother Gu, why don't you stand outside and let me take a look."

"Okay." Gu Chen also cooperated, opened the door directly, and came to the elevator entrance in the passage.

The door was opened again. Lu Weiwei shook her head at Gu Chen, feeling a little frustrated: "Junior brother Gu, the old man is right, I really can't see clearly."

Gu Chen returned to the room, carefully observed the situation at the old man's house, and asked him: "Uncle, are you the only one living in your house?"

"Yes." The uncle was quite cooperative.

"Before, we were working on a case in the room opposite. Have you been peeking at us through the peephole of the door?" Gu Chen asked again.

The old man nodded honestly.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Then why didn't you come out and explain it to us before?" Lu Weiwei also slapped her head, a little troubled.

The old man murmured: "Aren't I scared? My daughter bought this apartment for me to live in. My wife passed away early, so I live here alone and usually have no one to talk to."

"But just tonight, there are so many things happening across the street. I... I'm afraid, so I don't dare to come out. I can only hide at the door and observe you silently. I want to see how you work."

The old man was still very straightforward and informed Gu Chen and Lu Weiwei of the situation directly.

Gu Chen also expressed his understanding, and then recorded what the old man just explained in a notebook.

"That is to say, you saw a dark figure rushing out of the room opposite, and then he rushed back, and you heard a loud noise and a broken sound, right?" Gu Chen asked him.

"Yes." The old man nodded and said, "This man was walking in a hurry and seemed quite anxious. I was wondering at the time and didn't know what was going on inside. But I was an old man at home and I didn't dare to open the door.

Not long after that, I heard the sound of someone wearing high heels appearing from the opposite side."

"Moreover, the other party seemed to scream, and then I heard what sounded like the police, and then the police showed up."

Seeing Gu Chen record quickly, the old man said again: "I only know so much, and I don't know if I can help you."

"It's already very good." Gu Chen finally finished writing after a few "swish"s, and then smiled and said: "Uncle, thank you very much for your cooperation with our police work. Thank you very much."

In order to express his gratitude to the uncle, Gu Chen stood up straight with a snap and gave him a standard hand gesture.

Seeing this, Lu Weiwei followed Gu Chen's example and saluted the uncle.

Then the two of them returned to the scene of the crime after instructing the uncle to close the door before going to bed and remember to lock it.

Officer Wang and Li Ke's questioning continued, but it seemed to have no effect. They just made an extended explanation and investigation based on the previous questioning.

Seeing Lu Weiwei and Gu Chen return to the scene, Officer Wang couldn't help but curiously asked: "Lu Weiwei, Gu Chen, where did you two go just now?"

Gu Chen said: "There is an old man living in the room opposite. He said that he saw someone coming out of Zhu Ruiping's room in a hurry tonight."

"What?" Li Ke was also stunned, and quickly asked: "What happened next? Did you see that person's face?"

"No." Lu Weiwei said directly, and then began to explain to everyone the notes she and Gu Chen had just made about the old man.

At the same time, Gu Chen also began to squat on the ground.

He tore out a page from his notebook and began to investigate the broken glass at the scene.

"According to the old man's story, the mysterious black figure rushed out of Zhu's house in a hurry, then turned back in a hurry and broke the mirror."

"But if the man in black was the murderer, why did he go back after committing the crime?"

"Is there any trace of the scene that has not been cleaned up?"

Using a master's level of logical reasoning, Gu Chen began to quickly organize and splice all the information in his mind, and soon made some positive progress.

Gu Chen raised his head and glanced at Gao Liang and the thief. His eyes suddenly lit up: "Yes, this is it. I know who the murderer is."

Gu Chen quickly searched for some broken glass.

"Here it is, here it is, and here, yes, this is it."

Gu Chen was so happy that he wanted to give up...

If it weren't for the old man's previous tips, I might have overlooked this important clue.

It was also when he saw Gu Chen squatting on the ground, trying to push some glass fragments into a pile with folded paper.

Li Ke curiously asked Gu Chen: "Gu Chen, you... what are you doing?"

"I know who the murderer is." Gu Chen said excitedly while still sorting it out.
