During this period of contemplation, the police officers in the evidence collection team also investigated the scene.

And naturally, there were no special discoveries.

After the crowd dispersed a little, Zhou Yan also walked to the vicinity of the wooden box and started surveying without destroying the scene.

The entire wooden box was basically covered with blood, but it can still be seen that this box is the box I checked before, and the textures on the wooden boards have not changed. In other words, there is no situation where the magic group replaced the entire box with the people.

"hiss--"

Zhou Yan was embarrassed at this moment. This magic was really amazing. For a moment, he didn't even have a slight idea to crack it.

So he took out the detective notes as usual.

If you don’t decide when something happens, let’s take a look at what the brothers in the book say first~

When I opened the book, as expected, the brothers in the book began to discuss the case as usual.

【I'm so bad: This murder is really confusing】

"Uh..." Zhou Yan was embarrassed again. It seemed that the brothers in the book were also very upset about this case.

However, this may not be a murder. Maybe it was a sudden mistake in a certain link during the process of magic, which led to the tragic death of the magician.

[Song Xinzi: Zhou Yan, after Lu Renjia was "burned", he felt weightless for a second, that is, there should be an underground passage from the box where he disappeared.

Then he had a conversation with Zhenmei, one with questions and answers, so Zhenmei should still be alive at that time.

Lu Renjia touched Zhenmei's face in the darkness. He was a massage master and should not admit his mistake. Therefore, Zhenmei's head (regardless of whether the person is alive or not) should be in the box at that time, so both the mechanism and the head can go to the box to find clues.]

Zhou Yan was also stunned when he saw this message.

"Damn it? Brother is amazing! OK, I'll go and see the bonfire now."

As he said that, Zhou Yan quickly jumped off the stage and ran along the stairs of the audience toward the bonfire behind him.

During this process, he naturally did not waste time and was still watching the messages in the book.

[Lianyue Zhizhi: Zhou Yan, several key points.

1. Passerby A thinks that the fire is not hot, it is more like a blower.

2. Passerby A must have fallen into a secret passage.

3. Passerby Jia was talking to Zhenmei in the secret passage. He touched her face. Zhenmei said to him, "You have been reborn." Then he saw Zhenmei's part below his neck when he came out.]

Zhou Yan couldn't help but feel happy when he looked at the brother's message.

It seems that after so many murders, the brothers in the book have gradually become more and more professional. Now the clues are given so clear and organized.

So, this "Detective Cultivation Manual" is not only a person who practices himself, but also a person who practices the book.

Damn, after thinking about it this way, after a while, the people in the book have been cultivated into detectives who can stand on their own, and they all have the ability of [observer]. Wouldn't the people in the whole book be omniscient and omnipotent?

Then, as soon as I picked up the book, wouldn’t I have directly grasped all the cases?

Haha, if this is the case, let alone Sherlock level, it is not an exaggeration to be called the God of Detectives...

Okay, the fantasy ended here. Zhou Yan had already walked to the bonfire behind the theater and quickly pulled his thoughts back to the case in front of him.

The bonfire was placed on a temporary high platform, which was about two meters high from the ground, probably designed specifically to make it easier for the audience to see the bonfire.

Zhou Yan walked up the steps of the high platform, and then looked at the bonfire platform up close...

In fact, there is nothing to see. It is just a bonfire built with wood. It is much larger than the bonfire you usually set up during camping, because the bonfire is usually built with small branches, while the bonfire in front is made of very thick wood. In the middle of the bonfire, there is a thick wooden pillar standing upright, with a height of about 2.5 meters.

You can imagine the bonfire rack used to burn witches in the Middle Ages, which is similar to that one.

Zhou Yan knew at a glance that such thick wood would definitely not be easy to burn, and the wood is now intact and it doesn't look like it was burned at all.

So, this bonfire should be a prop.

He bent down and rubbed his hands against the wood, and found a layer of powdery stuff.

Zhou Yan stood up and asked the policeman who was still busy collecting evidence.

"Brother...what are these powders?"

The policeman was also very professional and quickly put down his work: "Hello, Detective Zhou Yan, these powders are phosphorus powder."

"Oh? Phosphorus powder?"

"Yes, we just found a blower under the bonfire. Above the blower is a bag filled with phosphorus powder, so this bonfire rack is a prop that can create [fake flames].

The specific method is to use a blower to quickly blow the phosphorus powder to about three meters above the bonfire.

When the phosphorus powder is dense, illuminating it with yellow and white lights can make it look like a shiny flame.

At the top of the wooden pillar above the bonfire, there is a heating device. When the phosphorus powder is blown near the heating device, it will start to burn and form a real flame.

But these flames are burned at a height of 2.5 meters, and there are also spray nozzles on the wooden columns to spray ammonium phosphate, so that all heat can be isolated from more than 2.5 meters, and it will definitely not burn people."

After hearing the policeman's words, Zhou Yan nodded. The fake flame was already as expected by him. After all, this is magic, so it is impossible to use real fire to roast people, right?

"Oh, by the way, we found this," the policeman said again, and then took Zhou Yan to the side of the bonfire.

At first glance, there was nothing special here, but the policeman kicked the floor with his feet.

With a bang, a piece of the floor collapsed.

It turned out that there was a small secret door here, enough for an adult to pass through.

"emmm..." Zhou Yan thought about something.

Based on the clues of a brother just now [Lu Renjia felt weightless after being "burned"], Brother Lu Renjia should have fallen into this small door at that time.

Zhou Yan lay down and looked down at the underworld.

But I found that there was nothing below...

There is no passage or mechanism, so you can only see the hollowing out below the high platform, and nothing else is inside.

Zhou Yan frowned and looked at the stage more than 30 meters away.
