Liu Chen quietly went down from the third floor to the second floor, and came to the room where the black shadow appeared, the corridor was outside the room, and he needed to pass through the room to reach the corridor.

There are several rooms here, and it is impossible for Liu Chen to open the door one by one to see if there is anyone, so he thought of a way to make a huge noise, which is very similar to the sound of an explosion, but because it is artificially created by Liu Chen, it will not cause any damage, just to lure the people in each room.

There was no reaction for a long time in a few rooms, and Liu Chen had a bottom in his heart, there was no one in this house, but this situation just showed that the person with the infrared night vision binoculars was a suspicious person, and this person had left.

Liu Chen opened the door of the room with confidence, and then walked through the room to the corridor outside, looking down in this corridor, he could just see the entire explosion restaurant, from this angle of vision, this suspicious black shadow should be paying attention to those policemen.

Why do you want to stare at the clues of the police's investigation, is it because you are afraid that some clues will be found by the police? Liu Chen kept an eye on it and made a bold guess, if the police did not find the clues left at the scene, then it was very likely that this clue was still at the scene, and of course it was also possible that it was taken away in advance by the black shadow who was watching.

Liu Chen used a professional laser pointer to find clues, and the concentrating effect of the laser pointer showed its advantage at this time, and no one could find Liu Chen's light.

There wasn't much in the hallway, and the search was quickly over, leaving no clues of the dark shadow at the scene, and continuing to go back to the room to check.

Through the scanning of the laser flashlight, there seems to be nothing special in the room except for some ordinary furniture, and the quilt is also neatly stacked there, and there is even a layer of dust on it, it seems that no one has lived in it for a long time.

Continued to rummage through some things in the drawer, and found nothing, Liu Chen felt a little frustrated, if he caught him as soon as he saw the black shadow, maybe the entire explosion case could be successfully solved, the current situation, I already feel that someone is manipulating and planning behind the scenes, but in case the police do not detect this layer of clues and close the case with an accident, wouldn't it let the real culprit get away with it, this is the result that Liu Chen is absolutely unwilling to accept, because two fresh and innocent lives were lost in this explosion.

Just as Liu Chen was about to leave the room and go to the scene of the explosion in the restaurant to see if there were any missing clues, suddenly a business card on the bedside table caught his attention.

He stepped forward to pick it up and took a look, this is a business card of Hongyu Group, and the business card is written with the information of Tao Guangren, the executive vice president of Hongyu Group, which makes Liu Chen feel very strange, why is Hongyu's business card here? Could it be that the owner of this household has a connection with Tao Guangren of Hongyu?

However, seeing that this business card is the latest version, and this resident should not have been back for a long time, it is very likely that this business card was left by the black shadow, and this is one of his secret strongholds.

This discovery is very important to Liu Chen, because there is a clear direction for the entire bombing case, and Hongyu Group may be the mastermind behind the scenes.

Liu Chen didn't plan to inform the police of this important clue, because the police's intervention was likely to make the situation more chaotic and hinder Liu Chen's tracking of Sun Quan, so he planned to privately investigate the relationship between Hongyu and the restaurant bombing, and the police would let them investigate it themselves.

Liu Chen left the house and quietly infiltrated the scene of the explosion again. The scene of the explosion was already a mess, except for some traces of the police on-site investigation and evidence collection, the broken stones on the ground and the chaotic dining table, you can imagine the tragedy at that time.

Liu Chen came to the kitchen, this is the core area of the explosion, the basic clues have been taken by the police, it is difficult to find anything, Liu Chen squatted on the ground with a laser flashlight and searched carefully, not letting go of any corner, after several repeated searches, Liu Chen saw a mark of a blade on the wall next to the stand where the gas tank was stored.

These traces are neatly carved on the wall in parallel, as if something needs to be placed, and there are some fine powders underneath, Liu Chen carefully opened these powders, and found that there were some black substances mixed in them, he reached out and put some of them in front of his nose and smelled them, this is a ** smell!

This **smell comes from a highly strong **powder, which is several times more powerful than the ordinary**, and under normal circumstances, after an explosion, these residual powders will burn out, and it is difficult for people to find its existence, but there are still some of this **powder left, Liu Chen guessed that it was because after the explosion of the gas tank and the shock wave formed by the explosion, a small part of the **powder was dispersed.

Liu Chen can roughly judge the murderer's modus operandi, using a gas canister explosion to hide the truth of the explosion, but the power is even greater than just exploding a gas canister, which is why a gas canister can almost level the entire restaurant, causing such serious consequences.

understands the modus operandi, so who is the murderer, and how did he get into the kitchen and install it?

Liu Chen took pictures of the clues and evidence at the scene and preserved them, and then investigated other corners of the kitchen, but did not get more clues.

As for how the murderer entered the kitchen, first exclude the chef, because the chef was blown up and killed on the spot, it is impossible for someone to blow himself up with **, and it should also be impossible for other restaurant staff present to be present, this explosion affected the entire restaurant, no one will joke with their own lives, and the person who can install ** must be someone who is not at the scene, and it is an insider of the restaurant.

Liu Chen is not so urgent about who is the real murderer, this is what the police should do, and the police will definitely conduct a detailed investigation of the restaurant staff, and then you can find out directly from the police.

Ouyang Lan is gone, and Yang Ziming, he should have the right to interrogate such a criminal case.

Liu Chen's current target is Hongyu Group, the business card left on the bedside table in the room can never be just an accident, Liu Chen believes that this business card is the breakthrough of the entire explosion case, maybe the case is not as complicated as it seems, once it is regarded as a deliberate murder case, then as long as it is through the suspect's mouth, you can quickly understand the truth of the matter.

In a house in the northern forest community, the snoring is rhythmically sounding, like a life rhythmically carrying out the last struggle for survival.

A languid body lay on all fours on the bed, and the quilt on its body slid to the ground, covering the wide slippers.

The whole room was filled with snoring, and suddenly the ringtone of the mobile phone on the bedside table broke the silence monopolized by the snoring, and the man on the bed rubbed his eyes and reached over and grabbed the phone, it was an unfamiliar number, and he picked up the phone with confused eyes.

"Hey, who?" the man asked, a little displeased.

"Look up. A low, eerie voice came from the phone.

"What? What did you say?"

"Look up. ”

"Look up, what are you looking at?" the man asked blankly, unconsciously following the voice on the phone and raising his head, suddenly, his hand shook, the whole person moved back, his eyes widened, and he saw a person sitting on the chair directly opposite!

"Who are you???" The man screamed with fear, groping for a long time before turning on the light in the room, and in an instant, the whole room was illuminated, but the man who was illuminated became even more frightened.

"Yes...... It's you ......" The man looked at Liu Chen in front of him with a trembling mouth, he was still immersed in a sweet dream, and his whole soul seemed to be drained and paralyzed.

Liu Chen put away his mobile phone, slowly stood up from the chair, and said with a wicked smile: "Mr. Tao, it seems that you have made a lot of money, living in such a luxurious community." ”

Tao Guangren asked in horror, "...... you How did you find ...... Find the ...... here."

"Is it difficult to find you?" Liu Chen asked disdainfully.

Tao Guangren shook his head hurriedly, "No...... No...... Do you want to ...... What do you have...... What's the matter?"

"I'm too embarrassed to disturb you when I talk to you and see that you sleep soundly. Liu Chen seemed to use a polite tone, but Tao Guangren heard a strong dissatisfaction.

"I didn't ...... Didn't bother, what do you want to say?"

Liu Chen took out a business card from his pocket and threw it in front of Tao Guangren, Tao Guangren took it and saw that it was his business card, raised his head in confusion and asked, "Is this ...... What does that mean? How do you have my business card?"

"Of course I won't have your business card, but the murderer does. Liu Chen's words carried a strong hint.

Tao Guangren was shocked when he heard this, and immediately understood Liu Chen's intention, but in this case, he chose to pretend to be confused: "What......? I don't understand what you mean, hehe. ”

Liu Chen saw that Tao Guangren was pretending to be confused, and scolded loudly: "Don't pretend to be garlic with me, since I found the door, you should be able to understand what I mean." ”

Tao Guangren straightened up from the bed, leaned on the back of the bed, and said embarrassedly: "I...... Liu...... Mr. Liu, I ...... I really don't know...... I don't know what you mean. ”

Liu Chen pointed out directly: "The restaurant bombing case in the middle gate of Jiangxia is your masterpiece, right?"

Tao Guangren's heart tightened again, Liu Chen's words made him feel a chill in his back, and beads of sweat even oozed from his forehead, because it was involved in the explosion, the situation suddenly became serious.

"Explosion...... Bombing, today I heard the news, but ...... But what does this have to do with us?" Tao Guangren continued to flatly deny that he had anything to do with the bombing.

"This business card was left behind by the murderer, how do you explain this?"
