Gu Qingyu didn't know whether to listen or not, so he only said, "Increase the scope of the search, and search the room where everyone lives." ”

There can't be only that part of gunpowder, and the introduction can't disappear so cleanly.

If you haven't found it for so long, it only means that you haven't been careful enough, or the scope is not large enough.

There must be something left too late to deal with.

While they were arguing, Li Jin just looked at the pile of black scum.

It seems that there is not only an explosion, but also a burning.

Is it liquid oxidized or solid?

Splash alcohol or gasoline on it beforehand and then ignite it?

Do you mix it with black powder to make the device explode?

Li Jin suddenly realized, "Cotton." ”

"Huh?" The crowd was puzzled.

Gu Qingyu smiled, "The introduction is cotton, now find a place where all the cotton is." ”

Listening to his words, looking at him who was not surprised at all, Li Jin suddenly felt that he seemed to know early on that cotton was flammable, and it was impossible for him not to know the formula of black powder, so why didn't he say it? I'll wait until she finds out.

What exactly does he want to do?

After confirming the introduction, there seems to be some hope, and there is still some reluctance to fight.

"Third floor, search?" Chen Rufan asked.

Everyone was stunned.

Because when I first came, I was told that the third floor was not allowed to go up, it was Li Jin's private space.

What is Li Jin doing on it? Why don't you allow others to go up?

Gu Qingyu first glanced at Li Jin, then turned around and left, "Search the second floor first." ”

Everyone began to look for cotton one room after another, and the final harvest was a bumper harvest.

In everyone's room, there is cotton.

The two girls don't talk about it, makeup remover cotton and cotton swabs.

It's all used for makeup.

A large bag of cotton was found in Wang Er's room, and Wang Er explained with an ugly face, "Believe it or not, I like sports, so there will be large and small wounds on my body, and this cotton is used by me to smear safflower oil." ”

Sure enough, next to the cotton, there was half a bottle of safflower oil.

Chen Rufan and Lin Qian both have a small medicine box with a few small packets of cotton for stopping bleeding.

Their explanation was that no one could guarantee that they would not be injured when they came out for a trip, so they prepared a small medical kit.

It seems normal.

The clues that were finally found pointed to everyone.

After working for so long, even if they found the introduction, it was useless, and everyone felt a little tired of powerlessness.

Li Jin sighed, the road of finding an explosive device was impossible.

The murderer was so clever that he pointed all the suspicious suspicions at everyone present.

I'm not afraid that I'm suspicious, but when someone else is exactly the same as me, I'll see how you can catch me.

"Unexpectedly, Mr. Lin Qian, can you tell us what is the relationship between you and Chen Wanyi?" Gu Qingyu held a mobile phone in his hand and shook it at Lin Qian.

The screen of the mobile phone is on, and everyone can see that the lock screen of the mobile phone is a silhouette of a handsome boy, which is a photo of Lin Qian.

And this mobile phone is Chen Wanyi's.

Lin Qian glanced at it and looked indifferent, "I'm not familiar with her." ”

Gu Qingyu sneered.

Wang Er opened his mouth, a little surprised, but also a little reasonable, he was short-tempered, and he didn't get angry for the first time.

They stayed on the second floor, with Chen Wanyi's room at hand, and the strong smell of blood grew stronger and stronger, making people more and more frightened as time passed......

"This smell of blood is really big...... Chen Rufan touched his nose and felt that it was a little too pungent.

"I feel like there's something wrong with the timing of death." Suddenly, a small voice sounded low, it was Qin Xiaoyu.

"How?" Gu Qingyu's voice did not fluctuate, but his thin lips were pursed.
