Liang Fei paced back and forth in his office, looking extremely anxious.

Song Guo was annoyed by the way he was walking around. She raised her head and stared at Liang Fei.

Only then did Liang Fei sit down opposite of her, "You said it's been a few days already, why hasn't anyone contacted Chen Wu yet?"

Liang Fei touched his forehead with one hand and knocked on the table with the other. He was obviously very anxious.

Song Guo calmly glanced at Liang Fei, then rubbed her forehead and comforted him, "Don't worry. Since they dared to use the hallucinogen, they will definitely discuss about it again. We have already found Chen Wu, how could we not find out who is behind this?"

After she finished speaking, she winked at Liang Fei, tilted her head, and looked at Liang Fei, looking extremely mischievous.

Liang Fei looked at Song Guo's confident expression and then sighed, not being able to say anything else.

"They haven't contacted each other in the past few days. Did they alert us?" Liang Fei asked Song Guo with some hesitation.

Song Guo lowered her head in thought for a while. "No, we should know about it even if we investigate Chen Wu, but those people will definitely want to know what's going on, so they will contact Chen Wu again."

"But waiting is not a problem."

Liang Fei paced back and forth in his room. He had always disliked waiting like this, but today's matter could not be rushed.

"Then let's go to the scene and watch it again." Song Guo knew that Liang Fei was impatient, but she also had a faint feeling that there would be other discoveries.

Liang Fei nodded.

The two of them hit it off and soon arrived at the scene of the accident.

There was a big seal on the door, Song Guo felt something flash through her mind.

The dazzling sunlight shined on the glass wall across from them, giving off a blinding light.

Song Guo finally grasped the thought that flashed past her mind.

When Gong Chen was allergic, there were some unremarkable pieces of glass on the ground. When they investigated, Song Guo felt like she saw something shiny.

"There was a glass shard at the scene. We should investigate that shard." Song Guo patted Liang Fei's shoulder.

Liang Fei turned his head and stared intently at Song Guo. Her memory was truly exceptional.

"When did you see the glass shards? Why didn't I hear you say it? " Liang Fei's face was full of surprise as he looked at Song Guo, seemingly very happy with this important breakthrough discovery.

Song Guo hesitated for a moment as she thought that they would make a move soon. If Chen Wu knew that they had discovered these glass shards, he would have sent someone to clean them up.

"Alright." Liang Fei nodded. The two of them quickly assigned the direction of the investigation and split up.

Song Guo had very few people walking on the stairs until now, but the elevator had surveillance. The safest way was probably the escalator.

She began to search along the stairs until she found something shining at the corner of the stairs. She bent down to pick up the fragment and followed it to a room on the third floor where the glass had been broken.

She quickly took out her cell phone and called Liang Fei, "Where are you right now?"

By the time Liang Fei received the call, he was already panting from exhaustion, but his tone was still full of excitement when he answered, "On the opposite floor."

"I'm on the third floor at the scene of the accident. Hurry over." Song Guo hurriedly replied. She wanted to see what else was in the room on the third floor, but jumping in in broad daylight would arouse suspicion.

Liang Fei almost sprinted to the third floor. Before he could stand still, he saw that Song Guo's hand was already full of glass shards.

She pointed at the broken glass. "Look."

Liang Fei raised his head to look at the shattered glass, feeling that something was off.

If the glass had been smashed by someone, it would probably have been smashed from the outside. The glass shards should have landed in the room, but now the outside of the room was filled with glass fragments, "What did you find?"

Song Guo thoughtfully looked at the glass, "Look at the broken glass in this room, there's something strange about it. Contact the property and let it open, I think there's something fishy going on in this room."

"That's right, the traces of broken glass seems to be new. People are so particular about it now, how can they just let the glass in the house shatter?" Liang Fei also touched the broken glass.

Those cracks were all new. They should have been shattered not even two days ago. Otherwise, there would have been dust on them.

Liang Fei and Song Guo looked at each other and said in tacit understanding, "I think we've found the crux of the matter."

Song Guo excitedly said, "Hurry up and find the properties."

Liang Fei also nodded.

Song Guo took a few simple photos and ran to the property room.

The security guards in the property room watched as Song Guo and Liang Fei walked in valiantly, their eyes filled with suspicion.

Too many things had happened in this district recently, so they couldn't help but to be vigilant.

Song Guo took a step forward and went straight to the point, "Hello, may I ask who is the owner of the third floor of the building opposite us?"

The person looked down at Song Guo, as if he did not put the girl in his eyes, "For now, I have no comment."

Song Guo saw how they refused to cooperate, so she took out her ID from her pocket and showed it to the person, "We are here to investigate."

"About that, please wait a moment." The man took the identification card and carefully examined it. After comparing the photo with the other, he finally dispelled the fear in his heart.

"Okay, thank you." Song Guo replied politely.

After carefully searching the property on the computer, he said simply, "No one has lived on the third floor over there. This landlord only came to register once after buying the house. We don't have any other information."

Song Guo looked at the empty information interface and asked, "Can you give us the owner's personal information?"

There was a troubled expression on his face. He turned the computer monitor to Song Guo, pointed to the personal information section, and said, "This owner hasn't left any information yet. I'm afraid he can't do anything about it …"

"Okay, if you find anything, please contact me." Song Guo handed over a name card with familiarity.

The two of them walked out of the building with no results. Liang Fei's expression was a little ugly.

Song Guo felt that this matter was done in such a flawless manner that it should have been planned long ago.

Even though nothing had been investigated, he had a faint feeling that this matter was not simple.

"Don't be discouraged. After all, this matter will be investigated sooner or later. There is no need to be impatient." Song Guo looked at Liang Fei's dejected expression and lightly consoled him.

This man had always seemed so carefree. Why did he care so much about this case?
