Lu Shiyan nodded with a gloomy face.

"Carbon dioxide also helps combustion. With this string of events, everything makes sense."

Gu Qingcheng nodded: "How could there be so much carbon monoxide in this room? This is definitely not a simple matter."

Lu Shiyan said, "My dear wife, don't worry. Leave this matter to me. I will find out who is so bold as to put the children to death."

They returned to the living room hand in hand.

At this moment, the house was already full of people, and their faces all looked very bad.

Only three aunts and Lu's mother were not there. The other women were upstairs taking care of the children.

Seeing Lu Shiyan and Gu Qingcheng coming over, Mr. Lu asked straight to the point.

"Shi Yan, what do you think about this?"

Lu Shiyan had already felt something was amiss, and combined with what he had just learned from Gu Qingcheng, he was now certain.

"Someone wants to harm us."

Mr. Lu nodded: "I think so too."

But there was one thing he couldn't figure out: "Who on earth could be so bold as to openly set fire to a full moon banquet with so many people? Is this to provoke us?"

Father Lu was also puzzled: "Our family has always been kind to others and has basically never offended anyone. Besides, all the people we invited today are familiar with each other, so it should be even more impossible for them to set the fire."

Mr. Li said, "Yes, and the fire burned too fast. I felt that there was no smoke one second ago, and I thought my eyes were blurry. The next second, it was like it was burning like crazy."

This was a good opportunity for Lu Shiyan to interrupt the conversation. He quickly said, "Grandpa, I also think that grandpa is quick to say this. There are hundreds of people at the scene. Under the watchful eyes of everyone, any little bit of smoke can be quickly discovered."

"That means it took only a minute from the time we discovered it to the time it burned like that, and there was nothing in the room that could burn."

Everyone fell silent again.

Li Jiadong raised a question: "Could it be that something was added to help with combustion?"

Li Jiabing has experience in handling cases in this area: "I have heard the Minister of Public Security talk about this before. It was similar. It took only two minutes from the start of the fire to the raging fire. After the case was solved, it was found to be a high-IQ case. The criminal used carbon monoxide as an accelerant, hoping to use the rapidly burning fire to destroy the evidence at the scene."

Lu Shiyan suddenly felt that his uncles were really smart. They brought the topic to this point before he said anything else, and it was effortless.

He quickly added fuel to the fire: "Grandpa, I also support what my second uncle said. If someone wants to harm us, they will definitely not use arson. Even if a fire starts, it will be put out quickly."

Li Jiahuan: "Yes, grandpa, your status and position in Jiang City are extraordinary. Anyone with a bit of brains wouldn't dare to be so brave. I also think what Shi Yan and my second brother said makes sense."

Lu Shiyan continued: "Oh, Grandpa, I suddenly thought of a key point."

Mr. Lu: “You say!”

"Do you remember that Qingcheng said she felt dizzy and wanted to sleep, so I took her upstairs?" Lu Shiyan was a little excited. He didn't expect that the excuse he made up at the beginning would come true at this time. "I suspect that there was this carbon monoxide in the room, and Qingcheng smelled it and felt dizzy and sleepy."

Everything fits right.

Gu Qingcheng felt that if she didn't say anything at this time, it would be unfair to Lu Shiyan for all his efforts.

She pursed her lips and said, "Yes, Grandpa, I slept for a long time this morning, so it shouldn't be possible for me to feel sleepy during that time."

“It does smell a bit disgusting.”

Now the truth of the matter is moving in the right direction.

Lu Shiyan and Gu Qingcheng looked at each other, with a hint of pride in their eyes.

Mr. Lu takes this matter very seriously. It is as if someone is doing evil under his nose, and he must make the other party pay ten times the price.

Lu Shiyan volunteered: "Grandpa, let me take care of this matter."

Mr. Lu nodded.

"Okay, Shi Yan, I'll leave this matter to you. You must catch the real culprit."

"Don't worry." Lu Shiyan clenched his hands. He knew better than anyone how dangerous today would be if his wife had no space.

He didn't dare to imagine what kind of accident might happen to her and the children.

…

At the same time, in a house near the Lu family.

There was a loud "bang".

A slap was given.

"What's wrong with you? Didn't I tell you to only release carbon monoxide? Why did you light a fire? Do you know how much trouble this fire will bring us?"

The woman thought it through carefully. She originally thought that if she only released carbon monoxide, which has no smell or color and only diffuses in the air, no one would notice it.

It can be said that it is done without anyone noticing.

But why did it catch fire?

The woman kneeling below also felt aggrieved.

"I... I don't know why it suddenly caught fire. That thing helps with combustion."

A lot of gas was released, so it must have caught fire by accident.

The woman standing above snorted coldly.

"You were burned, but why were Gu Qingcheng and those eight things unharmed? How did you do it?"

"I...I don't know either..."

She was also very depressed: "Damn it! She must be lucky!"

As soon as the words were spoken, there was another "pop" sound.

A slap hit her in the face.

"Okay, the most important thing now is to get us out of here. I think you know what to do. I don't want you to have to clean up after you, otherwise I'll make you pay for it!"
