"Just to blow up that train?" Belmode asked.

"Well, she needs to make a big move in Japan to attract the rats that are biting her.

And I just wanted everyone on the train to have a little accident, so I hit it off and asked her to blow up the train. ”

Bai Heqing said as he took out his mobile phone and glanced at it.

Kiel messaged him.

"You're really big-hearted."

"Don't worry, she is absolutely professional in the explosion area, her homemade bomb is very identical, unique in the world, I estimate that the police at the scene should have reacted to it now......"

"So what? Who the hell is she? ”

"International Indiscriminate Serial Bombers – Lamia."

“……”

On the other side, at Teitan University, under the deliberate impetus of Mizumi no Nai of Rin Suzumura, Conan quickly unearthed the truth about Takasugi Yuto's death.

The murderer is Takashi Himuro.

Takashi Himuro, although this person is a cleaner at Teitan University, but in fact he came to Teitan University only two days ago, and the time point is the second day after Takasugi Yuto returns to university.

After two days of observation, Takashi Himuro discovered that everyone in the seminar room, except for Takasugi Yuto, would go to the cafeteria during their lunch break, so he found a suitable time and place for his murder.

And his killing method is also very ingenious, because Takashi Himuro does not use any special poisonous drugs at all, but the nitrogen that is the most abundant in the air.

The oxygen cylinder with the logo on the coffee table in the seminar room is actually a high-purity nitrogen cylinder disguised by Takashi Himuro.

One of the amazing features of the human lungs is that if the oxygen concentration in the air inhaled by the lungs is lower than the concentration in the body.

In order to readjust the oxygen concentration, the lungs draw oxygen from the body.

At such times, if a person continues to breathe in this low-oxygen air, the lungs will continuously draw oxygen from the body in order to maintain the oxygen balance inside and outside the body.

In this process, the person will gradually fall into a state of hypoxia until he dies of hypoxia.

In general, for an adult man to suffocate because of this characteristic of the lungs, it takes at least 13 minutes to remain in this state.

Takashi Himuro took advantage of this and infiltrated the unoccupied seminar room the night before yesterday when Yuto Takasugi and Rin Suzumura went to the cafeteria for dinner together.

This is also the only time that Takasugi Yuto has been away from the seminar room for a long time in the past few days since he returned to school, and taking advantage of this opportunity, Takashi Himuro quietly dropped a bottle of oxygen cylinder that Takasugi Yuto had put in a drawer.

At that time, Takasugi Yuto should have had a total of seven oxygen cylinders, five of which were newly bought, one was already in use, and one old one was still in a drawer.

According to the usage habits of normal people, Takashi Himuro replaced the old bottle with a high-concentration nitrogen cylinder.

So, this morning, Takasugi Yuto, who didn't know anything about it, woke up and put on this disguised nitrogen cylinder, and then took a breath.

At this moment, due to the sudden rush of high concentration of nitrogen into his lungs, Takasugi Yuto instantly fainted due to lack of oxygen.

This is also the phenomenon in the eyes of Rin Suzumura and others, Takasugi Yuto fell asleep again after waking up to take oxygen.

Of course, this is not enough for an adult male to suffocate to death.

Therefore, after Rin Suzumura and the others left the seminar room during the lunch break, Takashi Himuro sneaked into the room again and used the string of plastic bags with small holes at the bottom that Conan found in the seminar room to cover the unconscious Takasugi Yuto's head, temporarily creating an airtight space.

Then, he inserted the nozzle of the nitrogen cylinder into the plastic bag through a small hole, and continued to spray nitrogen into the head of Yuto Takasugi in the plastic bag.

It continued like this for at least thirteen minutes, and due to the impermeability of the plastic bag, for at least thirteen minutes, the unconscious Takasugi Yuto repeatedly inhaled a large amount of nitrogen.

Due to the huge difference in oxygen levels inside and outside his body, his lungs pumped out the oxygen from his body little by little on their own, until he gradually fell into a state of hypoxia and eventually suffocated to death.

This is the truth of his choking.

And afterwards, the reason why Takashi Himuro was able to know exactly when Rin Suzumura came back and skillfully used her to stage the scene and call the police was not that complicated.

Mainly because Rin Suzumura sent a text message to Takasugi before she returned, and she meant to tell Takasugi that it was time for Takasugi to get up and eat.

Conan learned from the officers of the Forensic Bureau that Takasugi Yuto had indeed received the text message on his mobile phone, and that it was still read.

But judging from the time on the text message, Takasugi Yuto had suffocated to death at that time, so the one who really saw this text message was actually Takashi Himuro, who was still in the seminar room at the time.

After seeing that Rin Suzumura was coming back, he hurriedly cleaned up the scene, left the seminar room and returned to a nearby corridor, waiting for Rin Suzumura to find out about Yuto Takasugi's death, and then pretending to be attracted to help Rin Suzumura call the police.

At the same time, the police also found the receiver and transmitter of the bugging device on Takashi Himuro's body and under the sofa in the seminar room, respectively, which seems to have been quietly installed by him the day before yesterday after Takasugi Yuto left the seminar room......

In addition, the washing sprayer that Takashi Himuro was carrying with him was also found to contain a high concentration of nitrogen.

He seemed to be thinking that a bottle of nitrogen might not be enough to spray for thirteen minutes, so he filled the scrubber sprayer with a high concentration of nitrogen.

This is also what Rin Suzumura said, the reason why the air conditioner this morning was not cleaned at all, the detergent was all changed, what did he take to clean it?

"Mr. Himuro, is there anything else you'd like to say?"

In the seminar room, the sleeping Kogoro leaned back on the sofa, and with his deep voice, everyone in the room turned their eyes to Takashi Himomuro.

The "woo ......" technique was exposed one by one, and Takashi Himuro's face finally showed a panicked look.

On the side, after seeing that Maori Kogoro finally found the murderer, Mizuki Mercyna, disguised as Rin Suzumura, showed a look of "I can finally get off work".

Then, she immediately switched to a cold and fierce expression, and suddenly turned around and walked to her desk in the corner.

"What's wrong, Rin-chan?"

Meguro was the first to notice her anomaly and asked.

Shui Wuren didn't answer him, still silently walked to the desk, took out the appearance of something she had prepared from the drawer, and then quietly hid it in her sleeve.

【Suzumura? 】

Looking at Rin Suzumura, who suddenly lowered his head and walked towards Takashi Himuro, Conan, who was hiding behind the sofa, suddenly had a bad premonition in his heart.

"Suzumura-san?"

Finally, Wataru Takagi also noticed something abnormal, and he subconsciously stepped forward, wanting to stop Rin Suzumura, who was still walking towards Takashi Himuro.

However, it was already too late.

After getting close to the right distance, Mizuno suddenly accelerated, rushing straight towards Himuro Takashi at a great speed, and then raised his hand and stabbed the fruit knife hidden in his sleeve into his abdomen.
