My Partner is Shiina Mashiro

Seeing that Xiao Ai was about to draw his gun again, Conan said hastily.

"Actually, the case is not as complicated as we imagined. We were all drawn into it by our own redundant thoughts."

"What we have been struggling with is "how do prisoners ignite highly volatile gasoline without hurting themselves"..."

Conan's words paused here.

"Then what if I say... the gasoline was ignited by Hikigaya Hachiman himself?"

"Actually, it's not surprising to think so... The director of the Sobu High Security Department once testified that he once found a plastic hose in the small pavilion in the Sobu High Court, and that plastic hose is now It is placed in the duty room of the security department, and if I am not mistaken, there must be Yuigahama Yui's fingerprints on it."

"So what do you think the plastic hose will be used for?"

"Plastic hose?" Xiao Ai said, "Generally speaking, plastic hoses should be used to transport certain liquids."

"Well, it's for transportation." Conan nodded, "I think it should be used for transportation of gasoline. That method uses the so-called "siphon principle."

Conan pointed to the habits on the bottled coffee that Xiao Ai was drinking, and continued.

"Insert the pipe into the fuel tank of the car first, and then take a deep breath, so that the gasoline will flow into the lower oil drum under the action of atmospheric pressure. The oil thief that the owner of the milk tea shop was looking for before, I think it should be Yui Hihama is right."

"Weird plastic hoses, lost drugs in the chemistry lab, oil thieves, and finally, the lost keys of Haruichiro the dog..."

"This is the so-called chain of evidence, right?"

Xiao Ai gave the answer instead of Conan.

"Yes, isn't this chain of evidence quite perfect?"

Conan drew a straight line on the notebook, and then filled the content above the line.

"Since a few days ago, Yuihama Yui has secretly collected gasoline and chemicals, and hid them in that deserted small foreign building. That night, Yuihama Yui sneaked into Sobuko and went to that small foreign building The mixed gasoline she prepared was taken from the building."

"After that, he opened the basement door with a key stolen from Haruichiro's office, walked in and was caught on camera."

Conan said while writing, when the content was filled here, Conan's face was a little indescribably confused.

"Later, Hikigu Hachiman used some method to bypass the surveillance video and entered the small room."

"Maybe Yuhihama Yui and Hikigaya Hachiman intended to use those chemical substances to increase the flammability of gasoline, but he definitely doesn't know how volatile the mixed gasoline he made is..."

"So in the process of dumping gasoline, the small room was filled with flammable gas very quickly."

"It's easy to analyze the next situation, let me try it, I can do it too."

Xiao Ai finished Conan's pen, and after getting Conan's consent, she spoke.

"When Yuigahama Yui or Hikigaya Hachiman ignited the gasoline, they were already sticking out in the sea of ​​flames."

"Actually, there should be another question here."

Xiao Ai drew a circle on the straight line filled with content.

"At this time, Hikigaya Hachiman and Yuigahama Yui should be able to escape. The door of the small room is actually only a few steps away from them."

"When they came to the small room, the door should have been opened, because if Hikigaya Hachiman and Yuigahama Yui found that they had accidentally closed the door like Kouichiro Haruichiro, they would definitely terminate their plan, otherwise It is tantamount to self-immolation..."

Xiao Ai thought for a moment, and just when Conan was about to explain his doubts, Xiao Ai snapped his fingers and answered his own question.

"When Hikigaya Hachiman and Yuihama Yui ignited the fire, the door was open, but after he ignited, the temperature in the small room rose rapidly, and the hot air flowed up, causing the air pressure in the room to drop. The door of the room and the upper part of the room The air vent formed convection. At this time, due to the effect of air convection, the door closed with a bang."

"Sometimes when the window is opened in the room and there is a strong wind outside the window, the door of the bedroom will be closed at once. This is the principle. I should be right?"

Xiao Ai spoke confidently, and gave Conan an expression of "I'm very good, please praise me" while speaking.

"You guys are quite smart."

Conan nodded with a smile.

"Theoretically speaking, this way, the oxygen in the room will be less and less, and the flame will gradually stop..."

Conan answered Xiao Ai's words, simulating the situation that Yuihama Yui and Hiki Valley Hachiman might encounter at that time.

"However, a man and a woman surrounded by the fire were terrified and wanted to find a way to escape from the place, so they ran to the water tank and opened the lid, but the entrance to the water tank was too small for adults to do anything. go in."

"After the lid of the water storage tank was opened, the basic structure of the small room was changed, and fresh air was allowed in, which made the fire grow bigger and bigger."

It's sad to say, a man and a woman who originally hoped to escape, but they didn't know that it was the door of the water storage tank that completely cut off their way of escape.

"Actually, even if you don't get burned to death, if Officer Liu doesn't show up in time..."

"Probably choked to death."

As a pharmacologist, Xiao Ai is no stranger to combustion. She knows that in the event of a fire, only a small number of people are directly burned to death by the flames, and most of them are directly choked to death by the smoke and dust caused by the flames.

"There was so much smoke and dust at the scene, if brother Liu Sen hadn't appeared, they would have been choked to death." Xiao Ai said, "The only difference is that their corpses can be preserved a little better, not as Now it's turned into a black charcoal like this."

"Yeah, in fact, Hikigu Hachiman does have a chance to survive." Conan said, "That brand new fire extinguisher can explain the reason."

"He must have tried to use a fire extinguisher but had no idea how to use it. Didn't even know that the safety plug had to be removed before using the fire extinguisher..."

Conan's voice lowered, even if he hadn't experienced it himself, just imitating everything that Hikigaya Hachiman and Yuigahama Yui had experienced in his mind was enough to make him shudder.

"Perhaps Hikigaya Hachiman pushed Yuihama Yui to the door with all his strength, and after Hikigaya Hachiman knew that there was no hope of extinguishing the fire, he must have been terrified and fell into a state of madness...I'm afraid the blunt head of his head The gunshot wound was caused by him hitting a wall while trying to escape."

"Yuhihama Yui was choked by thick smoke in front of the door and fainted. Hikigaya Hachiman watched the fire getting bigger and bigger, so he could only hide in a corner of the room, and finally, right there... was completely burned by the fire. "

"It's really a cruel way to die. Just thinking about it is enough to make people have nightmares at night."

"So, according to our reasoning, what is the reason why Hikigaya Hachiman and Yuigahama Yui lit the fire in the small room?"

Xiao Ai was not as sentimental as Conan, she raised her own doubts.

"As for their motives, I still don't know, and further investigations are needed. Maybe by that time, the reason why the vacuum flask was left at the scene can also be investigated. What's more, Hikigu Yawata's mobile phone has been Corrupted, but there may be a chance to extract some data from it."

"So there are not many doubts left?"

"You are right in saying that."

"Thank you, Mr. Detective."

Xiao Ai smiled at Conan, and Conan was stunned by that cute and cute appearance.When he came back to his senses, Conan saw Xiao Ai stretching out her hand in front of him with a smile.

"Pleasant to work with."

"Ah, how about a happy cooperation?"

The two little hands overlapped for a moment, and the two blushed at the same time quickly turned their heads away.

Conan looked at the back of Xiao Ai with some fear, and he gave a slight sigh of relief when he didn't see any phantom behind Xiao Ai.

Xiao Ai feels a little subtle, she has a feeling now, if it wasn't for Liu Sen's sudden appearance, maybe it would be a good thing to follow this little detective.

Chapter 250 The Fifth Detonated Zong Wugao

Going back to each house to find their own mothers, Xiao Ai rejected Conan's proposal to visit Dr. Ali's house. Taking advantage of the time when the policeman guarding the small room in the basement of Sobu High School had not yet recovered from anesthesia, the two elementary school students came forward one by one. Finally, he secretly left Zongwu Gao, which was heavily guarded.

Although there are still mysteries in the case that have not been solved, now is not the time to continue the investigation.Back at the house where Liu Sen lived in this dungeon world, Xiao Ai rested for a while, washed her hands and went to the kitchen.

Compared with the two "kitchen destroyers" Zhenbai and Gilgamesh, the tea-haired girl's cooking skills are obviously much better. When Xiao Ai has not left the organization, whenever she feels lonely, she will always use delicious food To help myself forget about missing my sister and parents, and thus I have developed a good cooking skill.

The body changed back to the appearance of childhood, the height of the stove was a bit high for Xiao Ai, stepping on a small stool, so that his little hands could touch the kitchen utensils next to the stove, Xiao Ai in an apron She really looks like a good wife and mother.

Cutting the meat, washing the rice, putting it in the pot, and stewing it, Xiao Ai was doing the cooking work with ease. After a while, the porridge was cooked. Slowly pour the meat porridge into the thermos.

Carrying the thermos bottle with some difficulty, when Xiao Ai opened the door of the room and was about to set off, a drizzle began to fall from the unbeautiful sky.

Holding an umbrella in one hand and a big thermos bottle in the other, passers-by on the street saw Xiao Ai struggling and showed their kindness one after another.

Pedestrians wanted to help Xiao Ai, but Xiao Ai still politely refused them one by one—even though she had been out of the organization for a while, Xiao Ai was still quite wary of unfamiliar strangers.

Cloaked with rain all the way, when Xiao Ai felt the hospital where Liu Sen and the others were staying, half of his body was already wet by the rain.Xiao Ai didn't care that much, the reason why she rushed to the hospital with so much effort was because Mu Mu Shisan sent her a text message - Liu Sen, who had been in a coma for several days, finally woke up.

Since the shooting accident a few days ago, Mu Musan, who was very annoyed by his subordinates' ability to handle affairs, simply led the team to guard the hospital in person, and now Liu Sen finally woke up, and Mu Mu Thirty finally woke up. It was a little relieved.

After chatting with Mu Mu Shisan for a few words, Xiao Ai, who looked anxious, finally saw Liu Sen lying on the hospital bed, and the police officers guarding Liu Sen's ward also thoughtfully left time alone for Liu Sen and Xiao Ai.

Xiao Ai sat on Liu Sen's bedside, unscrewed the thermos bottle filled with hot porridge, took out a spoon, and was thinking of asking Liu Sen if he wanted something to eat.Liu Sen didn't say much, and he didn't take his eyes off the TV he was watching.

Xiao Ai's hand holding the spoon stopped, curious to know what Liu Sen was watching. The variety show of Shimai TV was playing on the TV. Liu Sen looked at the men and women in the program with great interest, without taking his eyes off it. .

"Xiao Ai... Tell me, why do Japanese people have such big brains?" Liu Sen couldn't help asking while looking at a game playing on the screen.

"Big brain?"

"Well...why do you have to study how to use chips to eat noodles?" Liu Sen muttered to himself, "I'm so drunk, chips are so soft...you can hold noodles There's a ghost."

Xiao Ai thought for a while, "Probably to please the audience?"

"Well, it seems to be the case. Thank you for reminding me. Sure enough, people cannot avoid pleasing others in this world."

Xiao Ai blinked her eyes, lowered her head slightly, and did not answer Liu Sen's words.

At this time, a luxury airliner crossed the night sky. Looking from the small window of the ward, everyone in the ward, large and small, could clearly see the flight path of the airliner.Liu Sen was lying on the hospital bed, watching the passenger plane approach and then go away, with a delicate and complicated expression.

Xiao Ai looked at Liu Sen and asked in a low voice.

"Brother Liu Sen... what do you want to say?"

"Nothing to say... I just think it might be better to be like a machine and not care about others' opinions once in a while."

"...much better?"

"Yeah, live the way you are, is everything in the past really important?"

Liu Sen raised his right hand slightly, but the expression on his face was distorted when he just raised it, as if he had forgotten that it was just a short while before he was hit by 30 yuan metal fragments. The heart is less than five centimeters, so surviving is already considered a miracle. If you want to move around at this time, Comrade Liu Sen is simply trying to die.

The truth is this, Liu Sen also knew his physical condition, but he still struggled to raise his right hand, opened the concealment barrier, and took out a blank piece of paper from his arms.

"I don't care what happened in your past life, I only know that you are my sister Hui Yuanai."

Liu Sen said seriously, Hui Yuanai, who took the blank paper, froze in place.

"I can't explain things that are too specific now. If you think it's not a bad thing for me to be your brother, just write your name on it."

"Actually, there's no need to worry... It's okay to wait until you think it through before making a decision."

"...No, don't think about it." The brown-haired girl shook her head, because there were no pencils in the ward, Xiao Ai simply bit her index finger.

Yin Hong's blood dripped on the white paper, Xiao Ai wrote her name on the white paper without hesitation, it was not Miyano Shiho but Haibara Ai, after the name was signed, Xiao Ai could be said to be completely in harmony with each other. Say goodbye to your past life.

The huge and complicated information flow exploded in Xiao Ai's mind, and when the information flow was completely stabilized, even Xiao Ai's psychological quality was not bad, it was still difficult to accept this fact.

"Brother Liu Sen, you, Sister Zhenbai, and Sister Jill actually came from another world?!"

Xiao Ai cried out in surprise, and quickly covered her mouth tightly again.
