The Grammatical Investigator in Conan

There are four supernatural events mentioned by the old man Otonashi, namely, a will-o'-the-wisp in the building, blood in the toilet, a figure outside the window, and a woman burned by the TV.

The woman with TV burns has already seen it. If someone is responsible, the others should not be left behind.

Qin Zhibo pushed the door open and entered the toilet on the second floor. The dim light made the toilet look extremely dirty.

The toilet was full of insect corpses and spider webs, and a melodious smell of ammonia wafted from the toilet bowl covered with yellow dirt.

Maybe it’s because the older generation doesn’t like flushing the toilet, which is why there’s such a strong smell?

Qin Zhibo flushed the toilet casually.

Wow——

The water in the tank flowed into the toilet, and the originally colorless and transparent water immediately turned red.

Toru Amuro happened to walk in at this time and saw the red color in the toilet.

"Teacher, do you have hematuria?"

Considering that Qin Zhibo has reached the age of soaking wolfberry in a thermos cup, Toru Amuro believes that his suspicion is reasonable.

Qin Zhibo: "."

Qin Zhibo, who was suspected of having a problem in that area, was furious, "Idiot, how could I not close the door when I went to the toilet?"

"And this amount is even more outrageous than bloodletting. It seems that someone specially arranged it."

With that said, Qin Zhibo opened the lid of the toilet tank, but there was a colorless and transparent liquid inside.

However, Qin Zhibo, who had studied chemistry in junior high school, immediately thought of a possibility.

"It's phenolphthalein reagent"

Hui Yuan Ai's voice drifted faintly from the door, speaking Qin Zhibo's thoughts before he could.

Haihara Ai walked to the edge of the toilet, stared at the red liquid inside that was gradually flushed into the sewer, and said: "The phenolphthalein reagent turns pink when it encounters alkaline liquid, which is quite similar to this color."

"And the smell in the toilet. Normally, it wouldn't be so strong and pungent when there is a vent. This is a special smell that only chemicals have."

"Based on the principle of phenolphthalein changing color when exposed to alkali, it should be alkaline ammonia, which is ammonia water."

As a scientist who specializes in the field of biochemistry, Haibara Ai is very familiar with these extremely basic chemical knowledge.

It can only be said that the person who plays this trick has met a master.

But as soon as she showed off her professional knowledge, Huihara Ai regretted it.

I saw Toru Amuro looking at him with surprise in his eyes, obviously shocked by what he said.

Haiyuan Ai was stunned for a moment, but his brain immediately reacted and he quickly learned some of Ke's traditional speaking skills to save the situation.

"I heard this from the science teacher at school. We even did experiments in class!"

"The smell of ammonia made the classroom stink all afternoon."

Haihara Ai explained for a while and tried to pass the test in a cute way.

But Toru Amuro, who has read countless people, is not easy to fool. He can feel that there is a hint of deliberateness in Haibara Ai's performance.

But what bad thoughts can a little girl have?

At this time, Qin Zhibo came to the rescue and touched Hui Yuan Ai's head lovingly.

"Xiao Ai knows so much!"

"First go to Grandpa Otonashi to borrow a phone and tell Dr. Narumi that he is safe."

Qin Zhibo made an excuse to send Hui Yuan Ai away, then turned to Amuro Toru and said, "The pretender should be in the apartment. Let's find him together."

"Oh" Toru Amuro, who couldn't figure out Haibara, could only turn the page and responded seriously: "Yes, teacher."

At this moment, other people in the apartment heard the sound and gathered in the corridor in front of the toilet.

When Toru Amuro told the story about the toilet water turning red, the graduate student named "Mudan" walked into the toilet without believing it.

"Not at all." Graduate student Mudan denied as he stretched his head to take a look inside the toilet.

"Already rushed down." Qin Zhibo replied.

"Really?" Graduate student Mudan took a look at the toilet tank and didn't see the expected pigment, but he still insisted on his scientific theory angrily.

"Someone must have done it!"

The resident named Yotsuya who looked like a toad sneered twice, "Maybe it's true."

Bancho, who has a sad nose, also echoed, "The fun has begun."

In Qin Zhibo's view, the two people had similar personalities and seemed to be very interested in supernatural events such as ghosts.

The motive is currently unclear.

Several people were discussing whether the supernatural incident was true or false. After reporting that they were safe, Haihara Ai walked out of the room and happened to see the east window of the corridor.

Haibara Ai did not scream this time, but her eyes widened in disbelief.

Qin Zhibo noticed something was wrong in Hui Yuan Ai's eyes, and when he looked in the direction of his gaze, he also discovered the strange scene.

Outside the glass window, a strange figure slowly emerged from the void.

Its outline is extremely vague, but its human form is vaguely visible.

The jagged edges of this human figure are swaying like fire, similar to the ice and fire man in the forest, but in the real world, it seems like a real spirit.

This is

Toru Amuro's eyes widened in disbelief, because this scene almost confirmed that ghosts did exist.

If ghosts exist, then the ones who killed those two people were also ghosts?

Toru Amuro really didn't want to draw such a conclusion unless it was absolutely necessary.

But the evidence is right in front of you, even if you don't want to admit it anymore.

Just when everyone was surprised, Ban Ming sneered twice.

"Finally, the ghost who wants revenge appears."

"That of the woman who died in the park four years ago."

Before Ban Ming could finish his threatening lines, Qin Zhibo took the lead and put his head in front of the glass.

"Tsk~ It's just some moths."

Hearing Qin Zhibo's words, everyone's eyes widened in surprise, "Moth?!"

"Yes, it's just a moth. If you don't believe me, come and take a look."

Under the guidance of Qin Zhibo, everyone gathered in front of the glass window.

As the light got closer, it became clear that the black shadow above was created by moths covering the glass window.

But even so, people with trypophobia still can't stand the sight of moths gathering together.

"But, but, why do moths gather into human forms?" Yotsuya Toad asked in confusion.

Pancho was a little panicked at this moment, and explained tremblingly: "There should be some kind of force that makes these moths gather like this, right?"

Qin Zhibo was noncommittal, but old man Otonashi came out yawning.

Chemicals such as ether still have a great impact on the old man's body. After a while, he walked out of the room and joined the discussion.

"Is it the wronged soul of Tian Zhilei who was burned to cokes four years ago and cannot be reincarnated?"

Qin Zhibo thought for a moment and asked, "Is this Tian Zhilei the name of the woman who died in the park?"

"Yes." Old man Otonashi nodded, "The police found a tooth mold on the charred corpse and confirmed the identity of the deceased."

Hearing this, Qin Zhibo smiled slightly.

Whether it is a ghost causing trouble, you only need to ask the ghost himself to know.
