After Noah's reminder, Hasegawa Yu had already prepared himself mentally for the possibility that the blond senior would ask him questions about artificial intelligence.

But apart from visiting him to talk about things related to the song, Fūya Rei's behavior when interacting with him was no different from before.

"It seems that the seniors haven't discovered Noah." Hasegawa Yu gave an optimistic guess, "Maybe we hid it very well~"

Noah's Ark had a hunch that something was fishy going on.

Don't ask where the intuition comes from when the code is built with logic and rationality.

Artificial intelligence that has experienced fierce confrontations with insidious and cunning humans who are evil both inside and out knows one thing well.

Bourbon is silent, he must be up to something.

[Hmm.] Thinking this, Noah's Ark responded gently, "Xiaoyou, you don't have to dwell on this every day. Just keep a vigilant line in your mind."

"Okay~"

Hasegawa Yu, who always listens to others, put this matter aside for the time being.

However, there are always many small troubles in life, and when one is gone, the next one will come.

Hasegawa Yu noticed that Hagiwara-senpai's collapse value had been stuck at 75% for a long time.

Ever since Hagiwara Kenji's Houkai Value started to loosen, it has dropped by 1% or 2% every few days. It's not much, but the amount accumulated over time is considerable.

But now I haven't moved for nearly half a month.

Hasegawa Yu went to check the Houkai values of the others. Morobushi-senpai's was 86%, and the detectives of Investigation Division 1 were making the fastest progress, having reached 55%.

Unfortunately, the latter also got stuck like Hagiwara-senpai.

"I see."

Hasegawa Yu clenched his left fist and tapped the palm of his right hand. A small lightbulb seemed to light up in his head. "This is the stagnation period before major progress!"

"It's like I'm stuck on a problem for days and can't come up with the answer. Then one day, I suddenly have an epiphany and the answers to all the questions are clear. It's a huge instant achievement!"

Noah's Ark, not wanting to discourage the mermaid, thought for a moment and decided to encourage her. [There's a high possibility.]

"Is that so?" Hasegawa Yu rubbed his chin, lost in thought. "But how do I achieve 'enlightenment'?"

"What is Detective Hasegawa thinking about? He looks very serious."

"Inspector Megure." Hasegawa Yu looked sheepishly at the portly officer sitting across from him. "I've been told not to call me that. My reasoning skills are really average."

Not even good enough to be a detective.

"After all, Xiaoyou has helped us solve several cases. Isn't this just one of them?" Megure Jusan smiled and picked up the pen in his hand. "Let's take notes."

Hasegawa You cooperated obediently.

In the previous case, he only helped find the key evidence, and the police officers deduced the murderer's behavior themselves.

The police officers are really good people!

With a sigh, Hasegawa Yu walked out of the Metropolitan Police Department's interrogation room after finishing the statement.

"Hasegawa?"

Hasegawa Yu turned around when he heard someone calling him, "Section Chief Date."

"I see you again at the Metropolitan Police Department." Ida Kou walked towards the man.

At this moment, there was no one else in the corridor except them. The sturdy man had hair just slightly longer than a crew cut, a pair of very iconic thick eyebrows, and a hearty smile on his face.

The black suit wrapped around the well-trained body, showing off every powerful muscle without reservation.

It should be a very reliable image, but Hasegawa Yuu feels a little uneasy.

Since it has not been touched many times, Date Ko's collapse value is still 100%.

Attributing the strange feeling to the slight pressure caused by the full Houkai value, Hasegawa Yu scratched his head and replied, "Because there are really too many cases in Tokyo!"

Especially Beika Town.

Not counting the cases he had personally encountered, the number of cases Hasegawa Yu had seen in the past 26 years could be counted on one hand.

However, after coming to this world, it would be good if I didn't have more than two hands of cases every day.

Hasegawa Yu has limited time in a day and has not followed so many cases at once. Most of them were mentioned by Inspector Megure and others in casual conversation.

"Indeed." Ida Hang followed up his words in a calm tone, "After all, the crime rate has been rising and has never dropped. There are always criminals to be caught."

Looking at the police officer in front of him, Hasegawa Yu was not sure whether the other party's words "too many to catch" were implying that there was no need to catch them at all, or whether it was just a simple sigh.

He decided to lean towards the latter. "No, as long as you really take action and be patient, it will work sooner or later."

"From my personal experience, there are fewer cases of theft than before."

Ida Hang glanced at the small distance indicated by the orange-haired young man's thumb and index finger, and couldn't help but raise his eyebrows slightly, with an expression that was hard to tell whether it was good or bad.

He didn't comment on the young man's words, but instead said, "When I came out of the office, I saw Officer Takagi and the others preparing to go out on a patrol. Does our Detective Hasegawa want to go with them?"

Hasegawa Yu waved his hand, signaling people not to call him that. "The title of detective always feels too exaggerated when applied to me, haha."

He checked the time, and seeing that there was enough time for another case, he said, "Thank you, Section Chief Ida, for the reminder. I'll go check it out."

After watching the person disappear around the corner of the corridor, Yi Dahang lowered his eyes slightly and took out his cell phone.

The keystrokes of the Seven Crows' tune echoed lightly in the air and instantly merged into the cold walls on both sides of the corridor.

After noticing footsteps behind him, Ida Ko put away his phone after sending the email.

"Section Chief Ida." Megure Juzo, who had sorted out the materials of the previous case, appeared behind him.

"Inspector Megure."

Date Ko nodded at him, his tone casual, as if chatting, "I feel that the atmosphere in the Investigation Section 1 office has been much more lively recently than before. What do you think?"

Megure Jusan's heart suddenly skipped a beat.

"It's almost winter, so I think everyone should finish their work early and leave work early."

The portly officer in the orange coat pulled his hat down, hiding the emotion in his eyes. "Section Chief, you know, the Tianjin Police Department doesn't have heating, and many officers don't want to be cold."

"The Metropolitan Police Department can be very cold sometimes." Date Kou looked at him steadily and agreed, "I understand. I don't like the weather like this either."

Megure Jusan: "Haha, it's rare to see Section Chief Date complain about these things."

Let’s ignore for the moment the two police officers who started a conversation about the weather, which happened a few hours earlier on the other side.

An office building in Hakata.

"Finally I caught you."

Matsuda Jinpei kicked the man to the ground and stepped forward to step on his back to prevent him from turning over. "He really likes to dig holes everywhere, just like a mouse."

The man lying on the ground coughed.

Based on the current posture, Matsuda Jinpei leaned over and grabbed the man's hair at the back of his head. "There are quite a few killers here who kill people just because they don't like each other, but... you are actually from Bourbon, right?"

The man, who was forced to raise his head back, did not answer. His Adam's apple kept rolling and he coughed again, with bright red liquid overflowing from the corner of his mouth.

"Tsk." Matsuda Jinpei let go of his hand irritably. "There's no point in not answering. I'll still blame Bourbon."

It's just blowing up that guy's office, not the organization's base.

He really cares about the things on his own territory, Matsuda Jinpei sneered, but unfortunately the boss can't control him.

I’ll dare to do it again next time.

"Buzz—"

Ignoring the half-dead man on the ground, Matsuda Jinpei answered the phone and walked out of the base, stepping over the messy ground. He casually wiped the blood from the wound on his cheek with his hand, "Hagi?"

"Is Jinpei-chan going back to Beika Town?"

A cheerful voice came from the receiver, and Hagiwara Kenji said mysteriously, "As a congratulations, I have a surprise gift for Jinpei~"

Matsuda Jinpei, who was used to being well-informed by his friends, declined to comment. "Where did you put the 'gift' this time?"

"The Beika Municipal Building," Hagiwara Kenji gave the address readily. "I've researched it carefully. It's definitely more difficult than last time."

"Hmph." Matsuda Jinpei chuckled, "I can finish it in three minutes."

"Don't be so confident, little Zhen Ping."

"Boom—"

Accompanied by a deafening explosion, Jinpei Matsuda took the last step and stepped onto the concrete floor outside the office building.

Sparks fell from the upper floors and landed sporadically on the ground, but there was no combustible material around to help it "show off its skills" like its brothers upstairs, so it had to gradually go out on the spot.

Pedestrians nearby habitually avoided the building and would not take a single step towards the scene of the incident, not even showing any surprise or panic.

Matsuda Jinpei leaned against his new car and lazily replied to his friend, "Five minutes then, no more."

"Tsk, at least respect my work. Kenji-chan has been super busy lately!"

"After I unpack it, I'll tie it with a bow and bring it back to you?" Jinpei Matsuda offered a way to show respect.

Without waiting for the person on the other end of the line to reply, the man with black curly hair raised his eyes and looked at the figure walking towards him in the distance, "Another annoying guy, I'll hang up first, hagi, see you in Beika Town."

After hanging up the phone, Matsuda Jinpei decisively opened the door and got into the car. He took off the sunglasses clipped to his chest and put them on before looking out the window.

"Gin, you know I can't do delicate work, so you don't have to worry about that upstairs. I'll leave the finishing touches of the Hakata mission to you. See you later!"

What nonsense is Granvit talking about in broad daylight?

The veins on Gin's forehead bulged, and considering that the other party was in charge of the organization's weapons research and development, he closed his eyes, thinking out of sight, out of mind.

Since when did the organization have so many troublemakers?

It's weird. Sooner or later, they will be shot one by one.

Rice Flower Municipal Building.

Hasegawa Yu, who had just rubbed shoulders with the police car of the First Investigation Division, looked up and saw only a gloomy sky, making it difficult to tell the exact time.

"It's going to rain heavily."

"Really?" Takagi Wataru stopped beside the orange-haired young man, "It's okay, there's an umbrella in the car."

Hasegawa Yu: "There might be thunder."

"What's wrong, Xiaoyou, are you afraid of thunder?" Sato Miwako crossed her arms and teased the mascot, "Do you want to go home? The lightning rod in the municipal building seems to be under maintenance."

"No." Hasegawa Yu wrinkled his nose.

Speaking of rainy days, mermaids always encounter humans who fall from ships.

The mermaid princess of the North Pacific is with the humans she rescued.

Better than the ending in a fairy tale, Hasegawa Yu thought.

But this is land, not sea, so this law (? should not apply.

And he's not a princess.

Ten minutes later, the mermaid prince really did not encounter the human who fell from the ship.

But it bumped into a human falling from the ceiling.

“!!!”

Hasegawa Yu was startled and tried to shake off the dust that was raised all around him, trying to see the situation clearly. "Are you okay?"

"..." Matsuda Jinpei stood up from the ruins of the ceiling, brushed off the dust on his body, and said through gritted teeth: "It's okay."

There is actually someone here.

Hasegawa Yu walked up to the man and looked him over. "Internal injuries should make us more cautious."

Jinpei Matsuda didn't want to talk.

Seeing that no one answered, Hasegawa Yu took out a Band-Aid and tissue from his pocket and handed it to him, "Since there are no internal injuries, take care of the wound on your face first."

Upon hearing this, Matsuda Jinpei finally turned his gaze over.

He fixed his gaze on the Band-Aid in the young man's hand, which had a super cute striped puppy pattern on it, and then slowly met his clear orange-gold eyes.

After a while, Matsuda Jinpei saw through the truth at a glance.

Where did this idiot come from?
