"I guess Miss Photon ran into the room and found the lights on inside. So in order to hide herself, she looked for the switches inside the house - there were three switches inside the door, two floor buttons and a light button, and I guess the second button she pressed was the light, and the first button she pressed was the first floor. ”

"Wait a minute," Reiko interrupted. "If this is an elevator, there should be four buttons: the first floor, the second floor, the third floor and the lights?"

"I guess this elevator works like this," Chiba replied. "The two floor buttons are designed like this. button 1, after pressing, first determine whether you are on the first floor by some means, if so, then go up the next level, if not, then go down to the bottom layer. button 2, determine if you are on the third floor, if so, then go down to the next floor, if not, then go up to the top layer. ”

"Cantharidin can blur people's minds and eventually lose their judgment." Chiba continued. "So when the elevator went down to the first floor, Photon passed out on the floor of the elevator, and the whole room was not all part of the elevator, some of them belonged to the floor of the floor instead of the elevator, and Photon's head fell right outside the elevator part."

"And at this time, on the second floor, Guangwei pressed the button outside the door, what does the button outside the elevator do?"

"You mean," Kenya immediately thought of the truth. "The elevator is back to the second floor?"

"Yes," Chiba said in a low tone. "The elevator went up, and Miss Photon's head was just outside the elevator, and just as the elevator was ascending, the head got stuck between the ceiling on the first floor and the elevator floor. And just like that, the force of the elevator ripped the head off. (There is actually a considerable distance between the elevator and the floor, but when the elevator arrives, it will use a mechanism to extend a thick wooden plank to cover the gap.) That's why the elevator will be able to tear the head off, not cut it off. ）

"This..." Everyone was stunned by this inference. And Qian Yu suddenly narrowed his eyes and picked up something from the ground.

"Brother Kenya," Qian Yu asked, looking at the object in his hand. "Is this Sister Shenxue's jewelry?"

"Huh?" Kenya looked at the studs in Chiha's hand and said in surprise. "Yes! How did it end up here? ”

"Please answer my question," Chiba looked through the glass of the hallway, looking in the direction of Kenya's room. "Brother Kenya, are you and Shenxue a couple?"

"Huh?" Kenya was stunned.

"If you don't deny it, then I'll acquiesce," Qian Yu said, walking to the end of the hallway, "Follow me." ”

On the first floor, under Kenya and Dr. Asasa's room.

"Seeing this familiar arrangement," Qian Yu pointed to the two buttons next to the door in front of him. "Do you have anything in mind?"

"This is also an elevator?" Kenya was surprised.

"Imagine," Qian Yu said slowly. Sister Fukayuki opened the door and saw Sister Mitsuko's head. If you are the closest person to her, she will definitely choose to go to you. If she had seen the strangely shaped blood stains on the elevator floor at that moment, she would have thought that it was an elevator, and she would have understood how Photon died, so she would have understood that the one in front of us was also an elevator. ”

Chiba pressed the elevator call button, but the door never opened.

"This..." Qian Yu narrowed his eyes and opened the protective layer of the tip of the umbrella tip at the front of the Traceless Umbrella, revealing the tip inside. "Get out of the way, I'm going to break the door!"

In the previous modification, Chiba added a lead block behind the cone at the tip of the umbrella, so that after the cone hit the target, the lead block hit the cone and hit the target again.

Qian Yu took a deep breath and poked the sharp cone into the door, and the door was poked out of a hole in response.

One, two, three, four, five, six, seven, eight. Eight small holes form a square, making the square door extremely fragile.

Qian Yu closed the protective layer, aimed the handle of the umbrella at the plank, and stabbed hard. "Hah!"

The planks shattered in response.

"Help... A weak voice came from within—it was the sound of deep snow!

"It's really like that... Qian Yu looked at the situation inside and said speechlessly. "The elevator here broke down during operation due to disrepair or other reasons. So Sister Shenxue was trapped in the elevator. ”

"Sister," Qian Yu asked through the opening. "Did you see Conan?"

"No... Didn't see him. ”

So where would Conan be??? After Qian Yu thought of this question, he immediately became anxious. "Brother Kenya, you go find tools to save my sister, and I'll go find Conan."

If I'm not mistaken, I've heard a sound coming from an elevator, then...

Chiba returned to the elevator where Photon had died, stepped on the small table inside, and knocked on the ceiling. "Conan? Conan? ”

"Is anyone stuck on the elevator?" A male voice came from behind, it wasn't Kenya's, it wasn't Koe's, it wasn't Dr. Asasa's, but Chiba just smiled.

"Uncle Hirata, you're awake!" Chiba jumped off the table. "My friend is stuck on the elevator, is there any way to get him out?"

"Right above you." Hirata smiled. "You have an umbrella in your hand, don't you? Just poke it, that plank is not locked. ”

"Hmmm... I see... ”

A minute later, Chiba brought the sleeping Conan down in a princess hug position.

。。。

It all goes back to when Conan went out.

"The corpse is intact, so there shouldn't be any killing traps in this room." Conan pondered. "Wait... The door opens after a few moments of pressing the button, and the head is ripped off with great force. What's more noteworthy is that the bloodstain doesn't seem to be very symmetrical, and the bloodstain below the neck seems to be much larger than the bloodstain above the neck, that is... Conan walked directly above the room where Photon was killed and pressed two buttons next to the door. Is this an elevator? ”

"Sure enough." Looking at the half of the blood in the room, Conan stood on the doorframe and thought with a smile.

At this moment, downstairs, Qian Yu pressed the button.

“！！！” An iron fence rose beneath it, passing less than half a centimeter in front of Conan. Then, the door behind Conan suddenly closed, and Conan, who was standing on the door frame, was slapped directly on the iron fence by the door. "Ahh (This is also the reason why Photon can only watch her head cut off and be powerless, her head stuck in the iron fence and unable to escape.) ）

When the elevator is halfway down, the iron fence also begins to retract at the same speed, remaining about 10 centimeters higher than the top of the elevator. And Conan, who was unconscious because he was slapped on the iron fence, also collapsed forward and fell on the top of the elevator, which was the muffled sound that Qian Yu heard from the room.
