Xu Wen doesn't have much interest in mystery stories, but as a modern person, he has inevitably come into contact with some.

Murder in a closed room is one of the most common types of mystery novels, and he has read several of them alone.

Memories of the past now came back to his mind one after another, and he looked around, trying to match the two sides.

The core key to killing people in a secret room is the "secret room", and many times, the way to crack it is also on this.

Is it a real closed environment where the inside and outside are all sealed and no traffic is allowed on both sides, or is it a fake secret room that is forged by some means?

Xu Wen looked into all the details of the house he could think of, and finally came to a conclusion.

"This is not a secret room. ”

He repeated his words, all eyes on him.

"It's really hard to fasten the door bolt from the outside, but what if the prisoner was prepared, designed a mechanism in advance, and used the mechanism to achieve this purpose?"

Organ?

The two masters of Song and Qin are both masters, and the trick starts from Luban, which is a branch of carpentry.

When Xu Wen talked about the mechanism, three or four feasible design solutions immediately came to their minds.

But after thinking for a while, they both shook their heads at the same time.

"Mechanisms don't come out of nowhere, they have to have parts. In such an empty room, a mechanism has already been discovered!" Master Qin said quickly.

Xu Wen didn't speak, but casually took out a piece of charcoal from the toolkit and drew a design on the table.

Master Qin shook his head as he looked at it, this kind of design was similar to what he thought, and it still couldn't solve his previous question.

However, after Xu Wen finished drawing this mechanism, he added a few extra things to it.

Master Qin's movements stopped, staring straight at the pattern on the table and not moving.

"Makes sense. Xu Wen drew to the end, and Master Song, who was silent, suddenly spoke.

"You mean, you can add an extra set of things to the outside on the mechanism, so that as long as someone is outside to reel in the line, the original mechanism can be pulled out from the outside?" Master Qin also saw it.

"Yes. And it was a hectic situation at that time, everyone's attention was focused on Senior Brother Zhou's body, and it was not easy for anyone to find out if the organ was taken away. Xu asked.

Master Qin looked at Liang Guming and Wang Jinzhu, and the two shook their heads blankly, indicating that they really didn't pay attention to anything at that time.

"Where's the evidence?" Master Song asked simply.

Not being noticed can also be interpreted as non-existent, and whether the matter is as Xu Wen said depends on whether there is evidence.

Xu Wen glanced at Zhou Zhicheng and invited, "Senior Brother Zhou, please do me a favor." ”

"Hmm. Compared with the first start, Zhou Zhicheng is much calmer now, he agreed, and stood beside Xu Wen.

Xu Wen's hand tugged at the room and said, "Now I need to know the size of some things, senior brother tell me." ”

If you want to know the size of things, what's the use of calling Zhou Zhicheng?

Some people were a little puzzled, but Qi Kun, Liang Guming, and Wang Jinzhu's eyes all lit up.

"The width of the window?" asked Xu.

"Two feet six inches. Zhou Zhicheng replied instantly.

"The height of the window. ”

"Three feet. ”

The height of the pane. ”

"There are two kinds of them, namely three inches and five inches and seven points. ”

"The width of the beds. ”

“......”

Xu Wen kept asking questions, and Zhou Zhicheng kept answering. From beginning to end, he stood still and did not move, without any intention of passing over, purely by visual inspection!

Almost everyone was surprised, except for the three candidates in the left wing last year.

Song Qin and the two looked at each other, Master Song picked up the ruler and measured them one by one without saying a word, and all the data were correct!

Zhou Zhicheng only relied on visual inspection to achieve the accuracy of the ruler!

The juniors and disciples of the class didn't expect Senior Brother Zhou to have such a hand, and Lu Cheng suddenly remembered the sad and regretful expression that the master occasionally looked at when he looked at Senior Brother Zhou.

Yes, such an apprentice has been abolished, and anyone will have to feel terrible.

When Xu Wen went back to his own world this time, he went through a round of evil supplements and read a lot of books, a considerable part of which were about the history of craftsmen.

He knew that there were people in ancient times who had such an ability, and they were basically great craftsmen who left their names in history, and passed down a lot of works and anecdotes.

When Xu Wen heard that Zhou Zhicheng was the biggest advantage of being the head of the quasi-object, he remembered such a legend, and now he directly called him to try it, which was really extraordinary.

Some old carpenters have been working for a long time, and can develop the corresponding sensitivity and intuition, and will have a certain perception of data. But it is still uncommon to be accurate to score like Zhou Zhicheng.

What's more, Zhou Zhicheng is so young, it is purely a talent to have such a performance.

Today, Zhu Gantang and the others came here to restart the case, in fact, they mainly came to Xu Wen, wanting to solve the "misunderstanding" and open the deadlock for both sides.

Now seeing Zhou Zhicheng show his talent, they are really a little sad.

On the other side, Xu Wen's work continues. He filled in the data he had reported one by one on the paper, and suddenly felt that something was wrong.

He vaguely had a feeling that the data he wrote down was not reported by Zhou Zhicheng, but came out of his mind!

He was stunned for a moment, and instead of speaking immediately after writing a piece of data, he looked to the other side and paused.

He was looking at the table, noticing its thickness. He swept his gaze up and down, and immediately got a data: ten centimeters, that is, three inches and three points.

Next to the table was a bench with a rectangular surface, two feet five inches long and six inches six inches wide...... Probably because of the wear, the eight inches to the left of the bench are a little narrower, with a three-millimeter depression.

Xu Wen was stunned - I also have this ability, when did I have it, why didn't I feel it before?

"Xu asked?"

It may be that he was stunned for too long, and someone next to him called him.

Xu Wen came back to his senses, resisted the urge to measure with a ruler and then make a confirmation, and continued the work just now.

According to the data reported by Zhou Zhicheng, Xu Wen made simple calculations and made marks in several places in the house.

Finally, he went all the way to one of the windows, tapped the lattice with his pen, and said, "Go and look outside." ”

A group of people followed him out of the window, where there was a swaying green bamboo, with a Taihu Lake stone underneath, and the moss and green grass next to it mixed into a piece of green.

Xu Wen bent down, groped carefully for a while, and said, "Found something." ”

He turned and stretched out his hand, and a small wooden strip lay on his hand, one large and the other small, clearly a wooden wedge.

"It's a clip, and it's used to fix the mechanism. Xu Wen said, "In the end, use the remote control to pop the card out, and the mechanism will automatically retract and fall out of the window, and the suspect can take it away when the time comes." ”

He looked around while talking to himself, and finally he pointed to a place and asked, "Who was standing in that position when Qi Kun came out of the inside to open the door?"
