Everyone who was approached to the church received a cipher paper, a 6 by 6 grid full of letters, forming a strange cipher table.

Except for the uncle, everyone else is the table attached to the email, and after comparison, it is found that the content is not the same, and the more special thing is the 3 times 3 nine-square grid framed with bold black line in the middle.

The letters in the nine-square grid are arranged inconsistently, but they are very regular, with "SA" in the center and the surrounding letters rotated clockwise or counterclockwise.

Gao Cheng is not a cryptographic expert, so he can't see why, but he didn't think about cracking the password by himself, just taking advantage of this time to keep in touch with the outside.

The Nagano Prefecture police had no further information, so he had to ask Xiao Ai to check the high schools of these people, as well as that Hihara Taisheng.

High school classmates who haven't seen each other for many years are gathered at the scene of Yasuo Hihara's death, presumably because of something related to these people's high school days.

Surveying from high school, there are no problems in this direction.

Not a particularly difficult case.

"Aren't you going to Kyoto to deliver something?" Xiao Ai purchased a batch of experimental materials and was about to get busy when he received a call from Gao Cheng and asked strangely.

"Halfway through, I came across a case...... Anyway, help me check the high schools of these people first, I have already sent you the specific list, this case is likely to be a serial homicide, and I feel that someone is not far from being killed. Gao Cheng said cautiously.

He came to this kind of ghost place because he thought that there would be a case, and if he let the murderer succeed when he knew that something would happen, he would be too sorry for his current identity.

"Don't think about any codes yet," said the hat girl Furuura Yue shivering coldly, "Is there any way to keep warm?" You can't freeze like this overnight. ”

"It's really cold today."

"Then find something to burn and light a fire in this jar at the door to keep warm."

The uncle took action and put aside the secret word for the time being.

Regardless of whether there is any case or not, if you don't want to find a way to survive this night, you will have to freeze to death.

"This church is so big, and the wind blowing through the cracks is swishing, so you shouldn't have to worry about lack of oxygen."

"Take out the water and food you are carrying, and divide the ......"

"I remember Joto, you always bring some sweets, right?" The uncle unconsciously became the backbone of the backbone, and he thought of Gao Cheng's habit when he had an idea, "It's best to have sweets to replenish energy at this time!" ”

"You think too much," Gao Cheng said speechlessly, "I was confiscated when I came, and now I only have small biscuits on me." ”

When the young people heard this, they opened their backpacks one after another.

"Don't worry, I brought a lot of snacks, just let me know if you want to eat."

"I've got more water."

"I brought mints......

"I'll forget it?" Glasses man Kawasaki still drinking water? The sullen one doesn't seem to fit in, "I have my own water?" It should be fine if you don't eat for a night. ”

"You guy's cleanliness isn't good yet, are you?"

The church is dilapidated though? But barely sheltered from the wind and rain, and after a while, charcoal fires burned in the chapel? Plus food and water are available, and staying up all night is no problem.

Walking inside from the chapel is a conversation room and a warehouse? And a kitchen and toilet? On the second floor were the study and bathroom, as well as the rooms of two priests and nuns, and Gao Cheng took a cursory look around and found no traces of other human activity.

So? The planner who summoned everyone was now among those people.

Ground floor toilet? Kawasaki turned on the faucet and watched the spray of water suddenly become happy.

"There's still water here." Gao Cheng was surprised.

"Although the church is abandoned, the cemetery still remains," Kawasaki laughed, "for the grave sweepers?" Water is normal, but I was worried that the pipes would freeze. ”

"You guys seem familiar with this place? Have you been here before? Gao Cheng asked.

"yes, you used to come here to play when you were a kid? There is a well-sized plaza next to the church that can be used to play baseball. ”

Kawasaki bit the handkerchief with his mouth and began to carefully wash his hands? Is it true that he is a person with a habit of cleanliness? Washed several times before drying your hands with a handkerchief? Put back on your black gloves.

After Kawasaki left, Gao Cheng tested the water temperature, which was bitterly cold.

This kind of weirdo should be a technician, how can he become a bank clerk?

Immediately after the convenience, Gao Cheng noticed that the door in the tool room in the toilet was not locked, and there were traces of opening, and the lower part of the frame was slightly scratched by something.

Judging from Kawasaki's actions just now, it is clear that no one has been to the toilet before, and even if someone comes, there is no reason to enter the tool room.

"Click!"

Gao Cheng stepped forward to open the wooden door of the tool room, but suddenly heard a faint sound, and the moment his pupils suddenly opened to the side, he only saw a crossbow arrow flying out from between the tools, almost penetrating his eyebrows.

Shout!

Gao Cheng's gaze swept over the crossbow bolts embedded in the toilet wall, and looked at the inside of the tool room with a depressed expression.

A ballista on the ground was facing the outside, tilted upwards, and the wooden door was connected with a rope on the bracket, which would be triggered immediately as soon as someone opened the door, and everyone in the church except for Conan and the woman, no matter who came over, it would cause a fatal blow.

This kind of place has been set up by someone, and if it weren't for him who opened the door, someone would have been killed......

In the chapel, Mori Kogoro brings everyone together again to discuss it, because when he closes the door of the chapel to block the wind, he finds a new cipher paper.

Along with the cipher paper was a piece of paper with a diagram of the structure of the church.

"If you want to offer to me, go to the following places, come one by one, and collect the words of sacrifice for me...... Hihara Taisheng. ”

Does that mean there are other coded papers in the church? Damn, which bastard is making such a joke? "Uncle Maori was angry.

Anyway, his follow-up commission fee seems to have been lost again.

"By the way," Nishino, a young man with coral head, looked left and right, "Why didn't you see that boy named Joto?" He's supposed to be with you, right? ”

Without waiting for the uncle to reply, the glasses man Kawasaki took the initiative to explain: "He was still there when I came back from the toilet. ”

"I always feel a little worried, or ......"

"Is something wrong?"

Only then did Gao Cheng go back to the chapel, but he didn't reveal anything about the toilet, as if nothing had happened.

Just now, Xiao Ai sent him the information he had collected by email.

Now that we have a comprehensive understanding of the incident, all that remains is to find the murderer.

"Why have you been around for so long?" The uncle complained and continued to discuss, "Now it seems that there may be other cipher papers in the church, so let's look for them first......

"The above seems to mean that we want one place for each person, so let's allocate it first." Someone suggested.

"It's like a game."

"How about guessing the boxing?"

"Let's draw lots, Kawasaki has napkin boxes, just like when I used to choose a captain."

"I miss it."

The woman in the hat tore off a page of white paper from her notebook, folded it into nine equal parts, and cut it along the creases.

"Everyone, write your name on the paper," Coral Head divided the 9 equal pieces of paper to everyone, "forget it, children, and put it in this tissue box after writing." ”

"Is that okay?" The uncle was the first to finish writing, with a stinky face, and he was not interested in the nostalgia of these people at all.

At this time, I am still in the mood to play games.

"Maori?"

Coral Head saw the words on the note, his body paused slightly, his voice trembled, and he looked at the uncle and Gao Cheng standing at the back again.

"Maori and city households, shouldn't it be ......?"

"That's right!" Kannori Wakida snorted and said, "These two are the most famous detectives in Tokyo, Takanari Shiroto, and some people say that Sleeping Kogoro can easily see into people's hearts!" ”

The corners of Gao Cheng's eyes twitched slightly.

The mention of him was too bland, without any embellishment.

However, now that the detectives have appeared, will the prisoners continue?

He already somewhat understood the plan of the [Dragon Teng] prisoner, which was to arrange for someone to go to the toilet to search, thus triggering the death of the trap.

In this case, the person who can do it is the person who draws lots, and whoever jumps out may be a prisoner.

"Alright," Coral Head quickly returned to normal, and after collecting the note with his name written on it, he said to the others, "Let me be the captain at the time." ”

"No problem."

Gao Cheng's complexion was delicate.

This really jumps out......
