Snakes are definitely good at sneaking in.

The secret door in the castle is not seamless, and there must be ventilation openings in the secret passages.

Those places are inaccessible to people, but snakes can easily climb in.

Fei Chi has almost explored all the secret passages and mechanisms, and in some places, it is estimated that he has not even explored the palace to increase the generation.

After listening to this, Chi Feichi explained to Fei Chi, "You go to the restaurant first, and come back immediately after seeing Mamiya Masudai enter the restaurant, and I'll wait for you at the secret door in the second room on the second floor...... By the way, in the future, don't provoke the little girl who says that you are stupid and stupid, and if you go down with a bottle of chemical potion, you will be lucky to die with a skeleton left.

Fei Chi suddenly stood up and stared at Chi Feichi, looking dumbfounded.

So terrifying? Deceitful...... No, the snake liar, right?

Chi Feichi didn't say anything extraneous and opened the door of the bathroom, "Action." ”

……

In the restaurant on the first floor, the old and the young sit at the table.

"Wow! It's so hearty! ”

Yuan Tai couldn't take his eyes off the food.

A maid entered the door, went to the side of the palace and whispered, "Master Man, we can't find Mr. Chi anywhere." ”

"You guys look for it again," Mamiya nodded blankly and looked at Dr. Asasa, "Then let's eat first, Mr. Chi and their side will let the servants go to find him." ”

"Huh?" Dr. Asa hesitated, "But ......"

"It's okay, he's going to find the little boy who is hiding, and if he finds him, he'll bring the child to dinner." Mamiya is accustomed to compiling Chi Feichi's 'daily whereabouts'.

Gray Yuan was shocked, and thought that Chi Feichi was seen when he went to look for Conan, and quietly observed the expression of Miyaman: "......"

This uncle is also an expressionless and indifferent face......

Mamiya's expression did not fluctuate.

Sure enough, it's completely easy to get acquainted with Chi Feichi's whereabouts or something.

He was a little numb, and if the scientist couldn't find the treasure, he would leave......

No, can't give up!

But it's so hard to persevere......

On the side, Manomiya Masuyo, who was in a wheelchair, felt bad, although she knocked out the glasses imp who entered the secret door and locked it up, but Chi Feichi lived in the castle for a while, and it was hard to guarantee that he would not find anything.

No way! She's going to have to check it out!

"Help me get the food to the room, I'm going to the room to eat."

"Grandmother?" The nobles of the palace were a little surprised.

"Hmph, what scientist friend, I think he wants to find a smart guy to solve the puzzle, and he only lives here for the treasure of the castle," Masumiya Masuyo pushed the wheelchair and turned away, "My daughter came back and told me, I want to talk about her well, how can she be deceived by this kind of guy!" ”

The nobles of the palace were a little embarrassed, but when they looked up, they didn't seem to be angry, so they didn't say much.

"Help Mrs. Tai bring the food." Mamiya just explained to the maid with a flat face.

Gray Yuan Wai has been quietly observing the family, the old lady has forgotten that her daughter has died from time to time, and the grandson sees his grandmother scolding his stepfather, just ask a word, and the palace is even more eccentric, looking at the face is haggard and frightening, as if he doesn't care about anything else except the castle treasure, he can't help but approach Dr. Asasa and whisper, "Doctor......

"Huh?" Dr. Asasa also cooperated to lower his voice, "What's wrong?" ”

"Wait a while, find an opportunity to quietly call the police, Edogawa is afraid that something has happened, Chi Feichi is going to look for him," Gray Yuan mourned in a low voice, "Be vigilant, don't trust this family." ”

Even the nobles of the palace were excluded by Gray Plains.

It's not that she doesn't believe Chi Feichi, but she suddenly feels that the nobles of the palace don't seem to be normal......

"Huh?" Dr. Asa was unexpected.

"Don't you think this family is abnormal?" Gray Yuan lamented, "In comparison, Chi Feichi seems to be the only normal person. ”

Dr. Asa thought back on the experience after entering the castle, looked at the two people at the table again, and nodded, I don't know if it was a psychological reason, he suddenly felt that the atmosphere here was strange, and he could only sympathize with Chi Feichi silently.

It's not easy, it's not easy to get out of a place like Aoyama No. 4 Hospital, and it's like this for people who are temporarily staying......

"Let's eat first." Mamiya turned his head to greet the crowd, and if he knew what Ai and Dr. Asa were thinking, he would probably jump up from his chair excitedly.

He's the only normal person in this family, okay!

But......

In the atmosphere of the three children eating happily, Mamiya Man talked about the fire in the castle, the complicated appearance of being distracted, tangled, and haggard from time to time, and the behavior of the nobles of Mamiya eating silently, all fell into Dr. Asasa's eyes, and Dr. Asa was more and more sure that he felt right.

And before the palace returned to his room, Chi Feichi and Feichi had already entered the dark passage.

Fei Chi tracked the breath of fresh blood left by Conan all the way, wrapped around Chi Feichi's neck, and pointed the way.

Chi Feichi didn't use a flashlight or other light sources, only listened to Fei Chi's words, and walked leisurely in the dark passage, and his footsteps were inaudible.

At the same time, Mamiya Masudai returned to the room, always feeling uneasy, opened the secret door and entered the secret passage, and checked several secret passages entrances.

It's a pity that when Chi Feichi was in action, she had the habit of reducing and cleaning up the traces left by herself, and the traces of entry and exit were not something she could find.

After looking around, Mamiya Masudai didn't find anything abnormal, and went to Guan Conan's dark room again.

In the dim and stuffy space, Conan was already awake, but he was tightly tied by a rope, and when he heard the sound of the mechanism being opened, he could only fall to the ground and move in a different direction, looking at the place where the sound came from.

The door opened, and the glare of the flashlight hit him directly, stinging him from opening his eyes.

Manomiya Masuyo looked around the dark room with a flashlight and retreated.

"Hey......!" Conan shouted, but the only thing he could do was the sound of the door closing in the darkness, frowning in thought.

He thought just now that the other party was afraid of something unexpected and couldn't wait to come and kill people, but now it seems that the other party would rather him die a natural death.

And the other party's actions just now were as if he was sure that he was still there, or looking for someone......

Someone is looking for him!

And maybe you've already made it inside!

Dr. Asasa? Gray Plains? Or those three children...... No, most likely......

Behind him, there was a faint sound of a mechanism.

How could it be the back? There's a mechanism in the back?

Conan was puzzled, silently moved, and then moved in another direction.

In the darkness, Conan was as conspicuous as a glowing light bulb in the hot eye detection of Fei Chi, and he could even see his movements clearly, "Two steps to the left, six steps ahead, you can feel the head of the imp when you crouch down, and the imp fell to the ground and moved to face us." ”

Conan's eyes weren't infrared detectors, he just listened to the door sound in the dark, and then fell silent...... No, if you listen closely, there seems to be a slight noise.

It's just that the sound is so soft that he can't tell what's going on.

About five or six seconds later, a hand pressed on his head, and Chi Feichi's usual calm voice sounded above his head.

"Conan, are you awake?"

"Hmm......" Conan breathed a sigh of relief and whispered, "That person has just been here and has already left, and this is a closed dark room. ”

After listening to it, Chi Feichi didn't understand, "So ......?" ”

Conan was stunned for a moment, according to Chi Feichi's brain, he should understand what he meant, and took the initiative to explain, "It's okay to turn on the flashlight now, as long as she doesn't come in, she shouldn't find out, I'm tied up......"

Help him untie it, you have to be able to see it, right?

Chi Feichi: "Flashlight? I didn't bring it. ”

Conan choked, and came to the tunnel without a light source......

Wait a minute! In other words, Chi Feichi came all the way in the dark?

"...... on my watch"

'There's a small flashlight that can illuminate, untie me first' Before he could say these words, Conan felt Chi Feichi's hand touch the rope on his wrist accurately: "......"

"What happened to your watch?" Chi Feichi asked.

"No, it's nothing......" Conan looked at the darkness in front of him, and wondered a little if there was something wrong with his eyes due to the strong light of the Manomiya Masuyo flashlight just now.

In the case that Conan couldn't hear it, Fei Chi continued to talk to Chi Fei Chi about the situation, "The dead knot, it's relatively tight, it is estimated that it can't be untied, use a knife......"

"Don't move." Chi Feichi reminded him, took out a switchblade from his pocket, and opened it.

Conan was puzzled, feeling a chill between the two wrists that were tied behind his back, and then the sense of restraint disappeared, and he reacted that Chi Feichi was cutting the rope with a knife, and his scalp suddenly exploded, and he didn't dare to move.

Fei Chi: "There is also a position where the master's left hand is shifted to the left about twenty centimeters...... Stop, the rope is broken, and the next knife will pierce this imp in the back, okay, the last one is behind the imp's ankle ......"

Conan felt the rope break again, "I can ...... the rest"

Chi Feichi had already cut the last four-knotted rope according to Fei Chi's prompt, "What? ”

"It's not ......" Conan sat up, and while struggling, he pulled the rope around his body with three inner and outer loops, and still couldn't help but ask, "That...... Brother Chi, am I blind? ”

Chi Feichi was silent for a moment, "What do you say?" ”

Conan chuckled in his heart, and then suddenly reacted, he seemed to be stupid, untie the rope, and confirm it himself?

Turn on the flashlight on your watch, find that you can see, be silent for two seconds, and turn your head to look at the pool.

"How did you touch it?"

"That's how I touched it...... Chi Fei paused, picked up Conan, quickly entered the secret door where he came before, and closed the mechanism.

Conan's watch was still illuminating the crack in the closed door, and he suddenly noticed that there was also a line of light on the opposite side of the darkroom that was gradually expanding, and he couldn't help but turn his head to look at Chi Feichi.

Although I didn't see the person who opened the door on the other side, it is estimated that the only person who will come to come is the one who lives here in place of Mamiya Masudai......

If it weren't for Chi Feichi's quick reaction, it is estimated that they would have been blocked inside.

But that's a bit too fast, isn't it?

Pick up his time, the time to the secret door, and calculate the time when the secret door closes, almost before the other party arrives at the secret door, Chi Fei found out later?
