I teach kendo in Tokyo

This is so unscientific! ?

Kazuma growled. At this time, he was approaching the corner, picked up a folding chair by the wall and threw it back.

Kazuma wanted to buy himself some time, but the moment the folding chair collided with the incoming dart, the latter triggered a small explosion, and a large amount of irritating powder was sprayed out along with the explosion.

The living room suddenly became filled with smoke, accompanied by the violent coughing of the middle-aged couple.

"Tear gas?" So creative.

Kazuma covered his mouth and nose and whispered in praise. Although he held his breath the moment the smoke exploded, he couldn't figure out where his opponent was coming from now that his vision was blocked.

It is certain that the other party is of a completely different level from the extremely evil villain. It is possible that the mastermind behind the scenes saw that the situation was not good and took action directly.

Kazuma was on guard, regretting not bringing Masamune out. At this time, there was a very slight sound from the rear left. This sound may not irritate the eardrums of ordinary people, but it cannot escape Kazuma's heightened senses.

Kazuma turned around and unleashed a tooth thrust, using the feather duster he had just obtained. At least the handle of the duster is made of bamboo, so it can barely be used as a substitute for a bamboo knife.

The teeth of the feather duster poked at the figure behind him with the force of tearing through the smoke. The man probably didn't expect Kazuma to be able to capture his position, but he reacted very quickly and raised his left hand to block Kazuma's tooth protrusion.

Even if a feather duster were used by a swordsman, it would have the power to break bones and crush flesh, but the touch that came from that moment made Kazuma feel as if he had poked a steel plate.

"so hard!"

When Kazuma was stunned, the opponent turned around and removed the force of the tooth protrusion to the side, and at the same time, he hit Kazuma's head with a roundhouse kick.

Hearing that the voice was wrong, Kazuma hurriedly leaned back. A cold light passed across the tip of his nose, and a strand of hair was cut off.

"Holy shit!?"

How many weapons does this guy have hidden inside? Kazuma was frightened, but also angry. Kazuma let out a low roar and rushed forward with all his strength. At this time, the opponent had not yet adjusted back to his stance. Kazuma grabbed him from the waist and smashed through the door wall, fell over the edge, and both of them fell into the backyard.

There were clothes and sheets hung by the hostess in the backyard. The two people who fell in rolled over, but had no time to adjust. They roared and attacked their opponent at their fastest speed.

"Eh?"

Kazuma's fist touched his opponent's face.

The opponent's short stick also poked Kazuma's waist. The front end of the short stick flashed with lightning, but it stopped in front of his clothes.

"Police department supplement?"

"Kurosaki-kun..."

Kazuma was wearing a blue and white sheet, while Kurosaki was wearing colorful underwear on his head. In the sunny backyard, the two men stared at each other in the pile of clothes, maintaining this ridiculous posture and slowly died down.

**

Hearing that the most popular new police department in Sakurada Gate had just prevented a home invasion and robbery in its own area, the local police station under the jurisdiction of Laojie was greatly shaken, and immediately mobilized its police officers to deal with the scene.

Several Yakuza gangsters who were suspected of maliciously wounding others were taken back to the police station and detained. Since most of them, including their leader, the man in a suit, were temporarily unable to speak, the interrogation could only be conducted later.

However, the police found contraband such as knives and gasoline in the van near Aida's house. If these were used as evidence of attempted murder and were charged to them, they would probably have to go to jail for a while.

The police chief who came in person was very grateful to Kazuma, and his attempt to establish a good relationship with the upstart Sakurada clan was quite obvious. However, when he saw Kurosaki present, his face immediately changed, and he walked away as if ignoring his existence. .

At Kazuma's request, police officers from the local department quickly concluded the work of collecting evidence at the scene. After the police officers escorted the Yakuza away, Kazuma and Kurosaki accepted the hospitality of Aida and his wife in the messy living room of Aida's house.

"Alas, originally I wanted to avoid damaging the home as much as possible..."

Because the original sofa in the living room was overturned by the explosion and the spear, everyone had to sit on the tatami around the coffee table that was barely cleaned. Later, Mrs. Aida served tea, and Kazuma picked up the tea cup, looked around the living room like after a storm, and made half-truthful complaints.

"I'm very sorry. It's the official's negligence." Kurosaki, who was sitting opposite Kazuma, had black lines on his head and almost pressed his head to the coffee table. "I heard that many clinics in Tokyo have encountered accidents in recent days. I'm worried. Something happened at Aida's house, and I became anxious when I heard the noise inside... I'm really sorry, I really want to apologize to the police department."

"Forget it, it'll be fine if it turns out okay. Otherwise, I wouldn't have had the chance to see your strength."

Kazuma waved his hand magnanimously and glanced slightly at the entry above Kurosaki's head. In the fight just now, Kurosaki used at least four or five kinds of weapons, and none of them were just trying to impress others. His moves were so fast and precise that anyone else would have fallen long ago.

He is truly worthy of being the heir to Oniwa Shingen's mantle. Kazuma estimates that he will most likely not be able to defeat Kurosaki with his bare hands, but in a real sword duel, the odds of winning are mostly on his side.

"I'm so sorry." Kurosaki sighed with gratitude.

Kazuma picked up the tea cup, collected his thoughts for a while, then opened the door and asked. "Speaking of which, Kurosaki-kun, do you know Dr. Aida?"

"Yes, I have been taken care of by them since my grandfather's generation." Kurosaki nodded and looked at Aida Shunji next to him. In Japanese society, private clinics like this often also have community medical responsibilities.

If the Kurosaki family lived nearby, then most of the family members, young and old, would probably go to Aida Clinic for medical treatment.

"I see." Kazuma nodded. It is true that Kurosaki has a relationship with the Aida family, but when he heard about accidents at several clinics, he immediately thought that accidents would happen at the Aida clinic as well. There is still something unjustifiable about this.

Kazuma put down his tea cup and looked at Kurosaki, paused for a few seconds, and then confirmed in a serious tone. "Kurosaki-kun, you know about the 'Open Door Experiment', right?"

"...Opening the door experiment?" Kurosaki was asked but did not speak, but the one who made a surprised sound was Dr. Aida who was observing. "Police officer, where did you know this name? Also, what happened to the clinic one after another?"

"Well, a lot of things have happened in Tokyo recently, and I slowly connected the clues during the investigation..." Kazuma said, looking at Kurosaki, and after confirming that he had no intention of speaking, he answered it himself Use the topic to explain the cause of the incident.

From the day sleepwalkers appearing on the streets of Tokyo, to the common points confirmed by inquiry, to the door-opening experiment discovered through investigation, and finally, the fact that several clinics participating in the door-opening experiment have recently encountered unexpected disasters.

"...Aida Clinic is also a participant in the open-door experiment, so I speculate that they are also likely to attack here. Although those guys haven't had time to interrogate them, I estimate that they are most likely minions of the mastermind behind the scenes. Am I right?" Finally? That sentence Kazuma asked Kurosaki in a confirming tone.

"...The investigation was able to reach this stage in just a few days. The police department's skills are really amazing. I am impressed by this junior official." Kurosaki confirmed Kazuma's inference in a tone that was almost sighing. That "admiration" was probably the same I am truly convinced.

"Wait, so these are all true? The open-door experiment caused many people to daydream, and some people attacked the clinics that had participated in the experiment, including our family, in order to eliminate clues?" No matter how calm Dr. Aida was, he couldn't help it at this time. He panicked and said, "Damn it! I knew there was something wrong with that experiment! If I had known, I should have called the police at that time. Alas, how could I have agreed in the first place..."

"In that case, can you please tell me? What's going on with the so-called 'open door experiment'?" Kazuma stared at Aida closely and asked while the iron was hot.

When asked this, Kazuma couldn't help but feel excited. The investigation over the past few days, the origin of the symptoms of day sleepwalkers, the conspiracy of Fuzi Technology, and the root of all mysteries all lie in the door-opening experiment.

——Of course, considering the cunning nature of the mastermind behind the scenes, Kazuma does not expect to get a standard answer from Aida, but in any case, the feeling of being close to the truth is always exciting.

"Actually, I had no choice when I accepted the commission. A senior from university called me to ask for help. I don't know exactly what happened..." Under Kazuma's attention, Dr. Aida began to speak in a slightly troubled tone.

The Open Door Experiment is nominally a "social experiment" that Fuzhi Technology pays Waseda University to promote, and of course it also uses Waseda University's connections.

In Japanese society, which values ​​human relationships and ethics, it is sometimes difficult to refuse requests from senior acquaintances. Kazuma also quite understands Dr. Aida's helplessness.

According to him, the relevant information for the open-door experiment was provided by Fuzhi Technology, and Waseda University only acted as an introducer in the process.

Fuzhi Technology hyped up the door-opening experiment, but Aida and others who actually got the data couldn't see the significance at all. Although not everyone raised questions, they all shut up after receiving a large amount of sponsorship money.

Aida also started to promote it with the idea of ​​"it doesn't seem to be harmful anyway, so just treat it as a favor".

"What is the specific content of the experiment?" Kazuma couldn't help but confirm.

"The content of the experiment is actually very simple. Just gather everyone in the room, read out the handout on the door-opening experiment, then put on headphones to listen to some soothing music, and then watch some expansion films of beautiful scenery. The whole process lasts about two or three hours. Right? Rest and refreshments will be arranged at the end..."

Aida said as he recalled.

"Fuzhi Technology has no special requirements for experiments. I just need to record the names and addresses of the participants, as well as their feelings and experiences. Then, I can get a large amount of sponsorship money."

"...That's it?" Kazuma wondered. I don't know if his expectations were too high, but he always felt that this was far from what he imagined.

"Yeah, that's it. At first, I thought it was just a promotional project for the company to show off, and I didn't take it to heart. But I didn't expect that unexpected things would happen soon during the actual implementation, and as a result, I had to temporarily suspend the experiment..."

If you don't have fun with new books, why would you be interested in writing old books? I’m really happy about the new book, and the results are like this anyway. It’s fun to write something you like without having to think about the audience.
