Mamiya Mitsumi and Tian Tian Katsuo said that there was still work to be done, one went back to the room, and the other went to prune the flowers and plants.

The juvenile detective group led Xia Muxing and Nana upstairs.

"Why are Brother Muxing and Nana dressed so formally today......." Mitsuhiko looked at what Xia Muxing and Nana were wearing, "Didn't we come out for a spring outing today?" ”

Brother Mu Xing is okay, the casual suit with a thin waist, because it is a more relaxed occasion, so the buttons are not fastened, and inside is a gorgeous silver cross printed t-shirt, printed on the chest, about the size of an adult's palm.

Classmate Xia is more exaggerated, a whole set of small black dresses, dressed as if he is going to a banquet, if you come to spring outing, shouldn't you wear more dirt-resistant clothes?

Mitsuhiko looked at the friends around him, most of them were wearing dirt-resistant jeans and dark jackets, and Edogawa-san and Graybara also wore peaked caps.

"Well." Xia Muxing followed his friends upstairs, and then asked Conan, "Conan, what would you think if you saw me and Nana wearing like this outside." ”

Conan actually wanted to complain about Xia Muxing and Nana's dress, but he was preempted by Mitsuhiko, and now when asked by Xia Muxing, he seemed to realize something, "Adults are wearing casual suits, and there are even casual shirts with prints on the inside, which proves that they are not so formal occasions, or people usually don't pay much attention to those."

Children dress very seriously, this style of evening dress, well-dressed, at first glance is custom-made by large companies.

The accessories also fully consider the overall temperament coordination, using top hats, black lace-ups and other outfits, plus their own good looks, more like the kind of idol star who debuted in elementary school.

I think there are two options for this kind of obviously child-oriented dress, which will be to take the child to the stage event, or go to a solemn occasion to receive the award.

Attending stage events, there should be the cooperation of makeup artists and others, and just two people may be too busy.

I'm more inclined to go and claim the prize. ”

Ayumi's eyes lit up and she looked at Conan adoringly, "Conan-kun is amazing!" So much information can be analyzed. ”

Conan shook his head and said with a smile, "How can it be so powerful." This is obviously Brother Mu Xing reminding me. ”

"Oh? So what is it? Gray Yuan Wai smiled slightly, it was relatively rare to see Conan being instructed.

"He led me into the trap of mental inertia,...... No one would have thought that someone would really wear such a formal ...... Participate in the spring outing of elementary school students, although the location was later set in this castle, there is no problem with wearing it like this........" Conan laughed dryly, although he said so, but can you really meet people like Brother Mu Xing in society.

If I really saw Xia Muxing and Nana wearing this in the city, I would never have imagined that they were going to participate in the spring outing, and they were driving a sports car, and they felt that they couldn't fit anything camping.

Xia Muxing saw that Conan had made up so many things in his brain, and he was also under a lot of pressure, what to mention, thinking too much!

"It's just a matter of keeping a love for life and making it full of rituals." Xia Muxing smiled and touched Nana's head dotingly, "You can dress up beautifully, wear your favorite skirt and play with friends, and don't be afraid of adults scolding if you get dirty, this should be the children's favorite parents." ”

"I also brought three spare dresses that I could change if I got dirty, a white lolita style, a blue tomboy style, and a gray cool girl dress."

Ayumi and Gray Hara, who were beside him, glanced at each other, and their eyes communicated.

If I go home with my clothes very dirty, I will be scolded by my mother, QAQ.

If I get my clothes dirty, I have to wash ....... myself, which is a nuisance.

Then the two looked at Xia Muxing at the same time, their eyes full of longing.

Wow! What kind of fairy brother is this! I'm so envious!

Conan looked sideways at the two girls with shiny eyes, and Nana, who was beside Xia Muxing, pretending to be calm on the surface, but the corners of her mouth couldn't help but rise and betrayed.

I'm envious too, okay! I'm not envious of that dress! I'm envious of being able to play dirty!

Again, it's useless for you to be envious, people will have an exclusive maid to help take care of it when they go back! I remember that Uncle Suzuki said at the last party that he sent a maid named Maki Yumi.

"I prefer that I have an older brother who can make eel rice." Yuantai is a pure foodie.

"Brother Muxing's cooking is also a must." Conan added. "Last time, I made us a big table of Chinese food, and there are a lot of particularly delicious dishes that I can't name."

Gray Hara glanced at Conan, "This is not the reason why Edogawa-san, who patronized and ate, and even forgot to ask the name. ”

"It's so delicious that I forgot, isn't that a reason?" Conan half-moon eyes, as long as I don't feel embarrassed, the embarrassed person is not me. "Again, do you know what those names are?"

"Mapo tofu, sweet and sour pork ribs, spicy shredded pork, soup dumplings, sesame dumplings, fish-flavored shredded pork, fish-flavored eggplant......." Gray Yuanai's face was calm, and he reported the names of the dishes one after another.

"I haven't heard much of it, but I'm hungry......" Motota touched his stomach.

"We're on the third floor, do you still have the puzzle?" Mitsuhiko stopped in front of the door of a certain room and turned to look at everyone, "This house is located on top of the chessboard, and you can see the scene on the chessboard. ”

Everyone was walking and walking, and suddenly they talked about food, didn't they come to decrypt it?

Xia Muxing felt that someone seemed to be peeping at the corner of the corridor, but he didn't know which person in the castle was.

"Of course we have to see, after all, the puzzle is related to the treasure of this castle." Xia Muxing pretended not to find out, pushed open the door, and walked in.

Don't care about those people, adding them together is not a threat to you, and now it's best to prioritize decryption.

There are two windows in the room, the right window is on the right side of the center line, and the left window is only 10 centimeters from the wall.

On the walls hang old-fashioned clocks with hour hands pointing to 10 and minutes pointing to 2.

"Let's quickly slide down the position of this chessboard and chess pieces, and just half of the drawing, we saw Brother Muxing coming." Mitsuhiko and Ayumi pushed open the window, pulled out their notebooks, and continued to draw.

"Let me see." Motota squeezed in the middle, grabbed the window edge with both hands, poked his head out of the window, and stared hard at the chess board below, as if he could see the answer to the puzzle by staring at it.

"Motota! It's crowded! Mitsuhiko and Ayumi were squeezed away by Motota, who was standing in the middle of the window.

Xia Muxing walked over, "There seems to be a window next door!" And the view is not bad, maybe you can see what the mystery is over there. ”

Hearing this, Kojima Motota moved, gave up the window here, and strode to the next door, "I'll go next door and have a look!" ”

"He's so cheating...... Conan laughed dryly, then looked down at the notebook in his hand.

"How's it going, do you have a clue?" Xia Muxing didn't go to join in the fun with the children, and came over to ask Conan, in order to push the speed of the case, he could only spoil it.

Conan scribbled with a pen and seemed to be trying to decipher the way "Trying, the black pieces on the board are in the shape of a rotating arrow, and the white pieces are scattered parts, I plan to use ......."

Just now Xia Muxing said that he was not good at solving puzzles, although he didn't believe it, but Conan planned to talk about his thinking.

“EGG，HEAD。” Xia Muxing hooked the corners of his mouth, leaned over, and whispered in Conan's ear, "Egg-Head." It refers to intellectuals who can only say some crooked reasoning. It also refers to intellectuals who only care about reading books all day long, ignore world affairs, and think that they are knowledgeable. ”

Conan, who was thinking about ".....", knew the answer to the riddle fiercely, and he instantly made up the process of reverse deduction in his brain.

He's trying! He's right! But he just started! was cut off by Xia Muxing's words!

And say you're not good at solving puzzles! You later, just one glance, how did you solve it! I even shared my thoughts with him! Brother Mu Xing must be snickering at me!

The detective stopped breathing.

Angry!

A full three seconds later.

"Brother Muxing, you ......" Conan was angry, it felt as if you were watching a detective movie with relish, speculating on clues with interest, and suddenly someone rushed over to spoil the answer, which made you bored and made you want to shoot this spoiler to death.

But you can't, because you also know that this person hasn't seen it, it's just that this person is much faster than you.....

Seeing Conan's appearance, Gray Yuan Ai also became interested, came to Conan's side, glanced at Conan's notebook, and reversed the process through the answer given by Xia Muxing, "...... I see. ”

"What, have you untied it?" Mitsuhiko and Ayumi heard someone say that they came around with a drawn notebook, and they looked expectant, "Who solved it?" ”

"Give me ten more seconds, and I'll be able to unravel it in no time." Conan grabbed his hair and sighed in frustration, "Defeated again, obviously I came first....."

"Chess is arranged using English letters and numbers." Xia Muxing opened his mouth to explain, "We can find a chess piece, use it as the origin, and set its position as the starting position. ”

Xia Muxing pointed to the white knight on Conan's notebook, "The position facing the knight is the starting position of the chessboard, arranged horizontally A~H, vertically arranged 1~8, and arranged from top to bottom did not form meaningful words, so I tried to arrange them from bottom to top again." ”

"The single thing that was formed in the end was the Egg-head." Gray Yuan added calmly.

"Egg heads?" Mitsuhiko wondered, "What a strange word." ”

"Poof....... It's funny, do you mean a bare head! Ayumi mended her bald egg face and laughed.

"It is a proverb that refers to a person who is stupid in reading and thinks he is very knowledgeable, or an intellectual who can only speak crookedly." Nana popularized science for her two elementary school friends.

"Ahhh Help me! ”

Suddenly, Genta's voice came from the next room.

Xia Muxing rushed out as soon as possible.

What's the matter, the murder was committed in the room in broad daylight?

Xia Muxing rushed into the next door, and suddenly found a pair of hands on the window, tightly holding the edge of the window.

stepped and sprinted, and dragged Yuan Tai, a little chubby dun of nearly 100 catties, up, and it was quite heavy, "What's the matter, did anyone attack you?" ”

Conan, Nana and others also hurried over, looking anxious, and stood in a circle around the frightened Yuantai.

"What's the matter, Mrs. Yuan, did someone push you?" Conan instantly made up a bunch of clues in his mind, and quickly looked around the layout of the room, could it be that Yuan Tai saw something that should not be seen? Someone is going to kill him?

It can't be that Yuan Tai accidentally fell down by himself, right? That's stupid too.

"Uh......." Yuan Tai was a little embarrassed, "I was staring too much just now, my body stretched out too far, and I fell down......"

"Thank you so much, Brother Muxing." Yuan Tai turned his head and grabbed Xia Muxing's right hand hard, "It really scared me to death, just now I leaned out, and then I didn't catch it, and then I suddenly lost weight, and then I grabbed it randomly, and then I grabbed it to the edge of the window, and then, I thought I was going to fall to death......"

Yuantai's words were a little incoherent, but everyone understood his general meaning.

Conan was speechless, isn't it Yuantai, are you serious?! The index of recklessness on the yuan is once again raised to the upper limit of the value.

Yuan Tai looked really scared, her back was wet with cold sweat, and her eyes were still a little dazed.

Xia Muxing was also speechless, this bear child.

Forget it, comfort him, Xia Muxing patted Yuan Tai on the shoulder, "It's okay, you must be careful next time, it's too dangerous." ”

"Woo, Brother Muxing, you saved my life......." Kojima Motota snorted and cried.

"Learn this lesson and don't be so naughty next time." Gray Yuan Ai didn't know where to get two tissues and handed them to Kojima Motota, "Brother Muxing is not here every time, and you may not be able to catch it every time." ”

"What! I also want to solve puzzles to help everyone find the treasure! Kojima Motota took the tissue and wiped his nose, a little dissatisfied.

Gray Yuan's calm voice suddenly rose, "Then you will drop it again next time?" ”

"No, no, no, no." Thinking of the scene where he almost fell to his death just now, Kojima Motota's head shook wildly.

"We've just solved the puzzle!" Mitsuhiko patted Motota's shoulder and walked to the next room, "Come here, I'll tell you about it." ”

"It was Brother Muxing who solved it, and of course Conan said that it was about to be solved at that time." Ayumi reminded as she followed.

"I know, I was about to say it!"

Gray Yuan Ai glanced at Conan and Xia Muxing, who were observing the room, shook his head, and followed.

Nana glanced at Xia Muxing, and Xia Muxing gave a vague look to protect Xiao Ai and the others.

Nana understood and left.

Wait for a few friends to leave.

Conan just spoke, "Brother Muxing, have you found out?" ”

Conan looked at the window, and then at the clock on the wall, thoughtfully.

Xia Muxing also looked around at the layout of this house, just now the matter was urgent, and he only had time to drag Yuan Tai up, so he didn't have time to take a closer look.

The window on the right, ten centimeters from the wall, also has an old-fashioned pendulum clock and several bookcases full of books.

It can be said that the next room is almost mirrored by the wall in the middle.

But the windows are too close to the wall, and the distance between me and the next door is at least several meters, which is basically impossible for two windows with a 10-centimeter partition wall.

Explain that there is a space in the middle of the wall, and it is large.

"There's something wrong with that clock." Xia Muxing pointed to the old-fashioned clock with the pendulum.

Conan nodded, "Yes, I've heard that castles used to have this similar setting, as long as you turn the minute hand and set it to a fixed time, the secret door will open and enter the secret passage." ”
