Zheng Yuanli turned on the electric light next to him, but even so, the room was still a little dim.

He noticed that the gloomy single room contained a small desk that had not been removed, as well as a small locker and a single bed, and that there seemed to be signs of a poster on the wall. The mere fact that there is a poster shows that the original owner is a person who deliberately labels himself and hopes that others will recognize him as a certain person.

And this recognition is often related to group belonging. So, he is likely to be subordinate to someone. This explains why, when a tall tattooed man appears in Kings Cross, a goatee man follows him.

In that case, the idea of going to the site of the Kings Cross explosion should have been proposed by a tall tattooed man. He was one of those in the know, and his conscience was wounded and was wavering.

In this room, Zheng Yuanli preliminarily judged that it belonged to the man with a goatee.

And the posters on the walls, if you guess it correctly, used to be death rock or something. The reason why he chose such a poster is not necessarily because he likes this kind of music, but simply because he thinks that if he likes this kind of music, his friend tattoo man should be more accepting of him. That's why this guy added this kind of poster to his room.

However, there is a gap between people, and the more dependent people are, the more insecure they will be.

What's more, the goatee man, in addition to his four roommates, also has a necromantic in his room. It's hard to guarantee that he doesn't have mental problems.

So, if nothing else.

Zheng Yuanli put his hand on the head of the small bed and pushed hard.

Bang~

The cot was pushed to the other side of the room.

A pool of blood was found under the removed bed.

If nothing else, this is the mark left by the goatee's attempt to self-destruct after using drugs.

With these bloodstains, it's a spell medium that's much better than dust. Enough to find out where the goateeed man is now, and cast a spell on him.

After all, blood is the currency of the soul. Even the name can be changed, although it has been a while, and the spirituality has weakened, but it is only the degree to which the person is found.

Key traces were found.

"Yo, yes, it's very accurate, and I found the key clues all at once."

"Well, in fact, if you look carefully, you can find it."

"I'm not afraid of ruining the scene for you to give the detective, in case there are any clues that you need and then leak them out for you. My job is to help you protect the site. ”

"But... It's you who call yourself the Great Detective. ”

"Okay, I'll ask my brother if there's a knife and a test tube, these two things are always needed to collect clotted blood."

"Go ahead, basically people can find it. You collect it first, and I'll go to the attic and look at it myself. ”

"I haven't seen the attic either, because it's more eerie."

"Can you really call yourself a great detective like this?"

"I'm a pragmatist. As long as it can solve the problem, don't care about the process in between. ”

With that, Luna ran downstairs, and from upstairs she could be heard looking for her brother for a knife and a test tube. It seems that Lancelot actually had these two things with him, but in the car. The two of them were going out to get it.

Zheng Yuanli found an iron and white-painted ladder next to the goateached man's house, which should be the place to borrow the upper and lower attics.

Now that the remaining four people have already studied it, there is no doubt that judging from Zheng Yuanli's current judgment, these five people will not be the masterminds of the matter, and their ability and psychological quality are not enough to instigate such a plan.

What really made Zheng Yuanli feel relieved was the fifth person.

In this attic, what clues will he leave for him?

Zheng Yuanli put one hand on the ladder, and the iron ladder transmitted the winter chill into his palm. It didn't make him feel scared, but he had a hint of excitement about to face a difficult problem.

He strained his arms and glared at his feet.

I climbed the ladder hard.

Eventually, it took a lot of effort to get up to the top of this ladder.

Greet him.

It's one, empty.

Attic.

A cursory look at nothing but dust. There is no trace of anyone living here.

But that's just a cursory look.

There is nothing in the world that does not leave a trace, just like every time you drink water, your lips will leave a lip print on the cup, who would have guessed that even that has your DNA code. Therefore, if you can't see it roughly, then look closely, and if you can't see it carefully, then take a magnifying glass.

Traces that cannot be seen with a magnifying glass can be taken to the laboratory.

In the world, there is no trace that cannot be found after taking time. However, there are still issues of efficiency and ethics in the process of analyzing these traces.

Zheng Yuanli stepped into this attic, a room that he must not jump up. Because if you jump up, you'll hit your head.

The lighting in this attic was as dim as the other rooms before, and it was even more gloomy. This may be because the heating in this house has been stopped, and the neighbor will not install heating in the attic, and the only heat source is the slightest heat from the wall, which is naturally more gloomy and cold.

Zheng Yuanli took a closer look around, he looked down at the floor, the floor in the attic was old and had not been replaced. Maybe the owner didn't think that the attic would be able to live in it.

And this attic, judging from the way Zheng Yuanli climbed it himself, the people who live here probably don't even have beds. So how strong is the will of the people who live here?

According to Zheng Yuanli's current conjecture, none of the other four people have the wisdom to handle the serial bombing case. Then the mastermind can only be this person.

Zheng Yuanli searched carefully and found a slight burn mark in the center of the floor. This is supposed to be the trace left by the timer of the trial production of TNT bombs by the people who lived here.

According to the clues given by Luna before, TNT's timer is homemade.

TNT explosives need to be ignited with an open flame.

I don't know where I can get this knowledge, but I want to make my own timer and set an appropriate time. Zheng Yuanli believes that this person must need to do experiments.

That's why he chose to live in the attic. Although most laboratory environments will do this kind of experiment on fireproof board to avoid fire, this is not a laboratory after all. The person who did the experiment was also a layman, so that person did the experiment on the floor.

The same traces, in the room, after Zheng Yuanli carefully searched, there are still four places.

Zheng Yuanli's heart should have described everything clearly. However, time seems to be running out.
