Ke Xue: Xiaolan delivers goods to your door at the beginning

I initially suspected that Sōtarō Gōshi was a suspect. Nagao knew Sōtarō Gōshi's secret and was therefore murdered to silence him.

However, Ling, Xiangsi Meng Zongtai% Lang suspected that (when the case was discovered, he was not in Dalinban, so he was not a suspect).

"So, Hattori-kun, your lead has gone cold?"

"No, I suspect that Yasuto's death was related to a series of murders."

"Why do you say that?"

Hattori Heiji crossed one arm over his chest and stroked his chin with the other, pondering, "A dagger piercing a wallet and then plunged into the chest... This is exactly the same method used in the two murder cases that occurred in Toyonaka City and Makikata City in the last half month..."

Who were the victims in the two murder cases in Toyonaka City and Makikata City?

"Were the two deceased in Toyonaka City and Makikata City the supermarket owner, Mr. Hidetoshi Nagao, and the waitress, Ms. Tayo Nishiguchi?"

"Hmm? I think I've got it."

Hattori Heiji was somewhat surprised: "Hayashi-kun, do you have any clues?"

"Since the murderer has appeared in Toyonaka City and Makikata City, we might as well investigate."

"Yes. Great minds think alike. Let's go together tomorrow."

Hattori Heiji was overjoyed; finally, he had a friend he could connect with on the same wavelength to work on the case with.

When the other three girls heard that Lin Xiaofeng and Hattori Heiji were going to handle a case in another city, they immediately expressed that they wanted to go too.

Heiji Hattori cleverly assigned Kazuha Toyama an important task.

"Tomorrow, Lin-kun and I are going to investigate a case, not to play, so you guys shouldn't get involved. Kazuha, tomorrow you take Ms. Suzuki and Ms. Toyama to Osaka and have a good time. Don't let them come for nothing."

Seeing that Hattori Heiji was determined not to take her along, Toyama and Hajime decided not to try and force her.

Lin Xiaofeng also didn't want Xiaolan and Sonoko to come along. His investigation of the case was a pretense; his real purpose was to find Numabuchi Kiichiro. Numabuchi Kiichiro was a very dangerous person, and there was no need to take the risk with him.

"Ran, Sonoko, you two will go to Osaka with Ms. Toyama tomorrow. Hattori and I will be there and back as soon as possible."

"Yes."

The considerate Xiaolan and Yuanzi, not wanting to make things difficult for Lin Xiaofeng, agreed.

Upon hearing this, Hattori Heiji nodded in satisfaction at Lin Xiaofeng; this was exactly how a high school detective should be.

In the evening, after taking a bath in the Hattori family's luxurious bathtub, Lin Xiaofeng returned to his room to rest.

Unexpectedly, Ran and Sonoko came looking for them immediately after they finished showering.

"Hey, hey—why are you all here!"

Since both Hattori Shizuka and Hattori Heiji are home now, it's best to keep a low profile.

Xiaolan said shyly, "Yuanzi and I have discussed it. If you can't come with us tomorrow, you have to spend the night with us."

Sonoko chuckled and said, "I felt great exercising this afternoon, let's continue tonight!"

Lin Xiaofeng, sweating profusely, said, "Then you have to promise that the noise won't be too loud. The soundproofing in these traditional Japanese houses doesn't seem to be very good."

Xiaolan and Yuanzi immediately agreed and came to Lin Xiaofeng's sides, gently embracing him.

Needless to say, tonight will be another exhilarating workout for Lin Xiaofeng...

……

In the morning, Hattori Heiji drove his father's car with Lin Xiaofeng in tow.

"Do you have a driver's license, Hattori-kun?" Lin Xiaofeng asked suspiciously from the passenger seat. He remembered that in the story, Hattori Heiji was seventeen years old, not yet old enough to get a driver's license.

"It's alright, this is my dad's car, no one dares to stop it," Hattori Heiji said smugly.

Lin Xiaofeng remembered that Suzuki Sonoko had said the same thing.

The lives of Japanese samurai and ordinary Japanese people are vastly different.

Seeing Lin Xiaofeng sitting in the passenger seat with his seatbelt fastened, Hattori Heiji asked, "Lin-kun, shall we go to Toyonaka City or Makikata City first?"

"Let's go to Mufang City first," Lin Xiaofeng said without hesitation.

Vermouth's decision to send Lin Xiaofeng to hunt down Numabuchi Kiichiro was not without clues.

The reason Lin Xiaofeng was sent was because the previous members of the organization lost track of Numabuchi Kiichiro, leaving them no choice but to send Lin Xiaofeng to fill in. Lin Xiaofeng is a detective, and the plan is to use his detective skills to find Numabuchi Kiichiro.

Makikata City is the last place where Kiichiro Numabuchi was last seen.

Hattori Heiji arrived at Makikata City 1-chome as requested by Lin Xiaofeng.

This is the home of Kiichiro Numabuchi's mother.

"What are you doing here?"

"You'll find out if you follow me."

After getting off the bus, Lin Xiaofeng went straight to Numayuki's mother's house.

After Lin Xiaofeng rang the doorbell, a tired-looking old woman opened the door.

Before Lin Xiaofeng could speak, Numabuchi's mother spoke first.

"If you're looking for Numabuchi Kiichiro, please leave. I don't know his whereabouts either."

"Numabuchi Kiichiro? Who is that!" Hattori Heiji looked at Lin Xiaofeng in confusion.

"So you're the person involved in this serial murder case," Lin Xiaofeng said calmly.

Numabuchi's mother was about to close the door when Hattori Heiji stopped her.

"Wait, even if Numabuchi Kiichiro isn't home, please let us in. Your son is involved in a series of murders and is in a very dangerous situation. Please allow us to investigate."

"Who are you?" asked Numabuchi's mother.

Heiji Hattori grinned and straightened his baseball cap: "I am Heiji Hattori, the high school detective from Kansai."

Hattori Heiji then pointed at Lin Xiaofeng: "He is Lin Xiaofeng, a high school detective from Kanto."

Upon hearing that the two were detectives, Numabuchi's mother let them go.

The two entered Numabuchi's mother's house and found it to be very messy and chaotic.

Numabuchi's mother said to the two, "Before, some people came to my house looking for my son. I told them my son wasn't here, but they wouldn't believe me and made a mess of the house."

Lin Liufeng's father gave Hattori Kyuheiji a dirty look, and then said to Numago Awakening's mother, "Why don't we help you clean up?"

Heiji Hattori immediately understood Lin Xiaofeng's meaning. Under the guise of cleaning, he conducted a thorough investigation of Numabuchi's mother's house: "That's right... not only is it messy, but there's also a lot of dust on the walls, ceiling, and windows."

Numabuchi's mother didn't think much of it and said gratefully, "Thank you so much."

The two immediately split up to clean Numabuchi's mother's house, turning it upside down in search of all the clues.

After cleaning up, Hattori Heiji actually found a clue and quickly called Lin Xiaofeng over to check on the beggar.

"Lin Jun, come here quickly, look what I found!"

Hattori Heiji called Lin Xiaofeng over and took out a photo he had found in the cabinet.

"This photo is..."

Lin Xiaofeng looked closely and realized that the photo was a group photo, a group photo of six people.

In order, they are Yusuke Sakata, Hidetoshi, Tayo Nishiguchi, Yasuto Noboru, Kiichiro Numabuchi, and Shizuka Hattori.

154. Aunt Jinghua is so beautiful, she definitely can't be the murderer.

"How come my mother has a photo with Yusuke Sakata, the three victims, and Kiichiro Numabuchi? What's going on?"

Hattori Heiji interrogated Lin Xiaofeng.

Lin Xiaofeng was equally surprised; he hadn't expected to get involved with Hattori Shizuka.

"I think we'll have to ask Numabuchi's mother to get the answer."

After finishing cleaning the house, Hattori Heiji and Hayashi Kofu went to the living room to question Numabuchi's mother about the photograph.

After thinking hard for a while, Numabuchi's mother remembered the background of the photograph.

“I remember now, this is a photo of my son and his fellow students from the same driving school many years ago. I remember that my son failed his driving test that time and threw a tantrum at home.”

"Is there anything strange about this photo? Is it related to the serial murder case my son is involved in?"

"If you can't explain it, then forget it..."

Numabuchi's mother's emotions crumbled.

Hattori Heiji was at a loss. Three of the six people in the photo were already dead, and it was easy to conclude that one of the three people still alive in the photo was the murderer.

Hattori Heiji looked at Numabuchi's mother seriously and said solemnly, "Auntie, I don't know the truth yet. I can only tell you that Numabuchi Kiichiro is involved in a serial murder case. As a detective, I will definitely bring you the truth."

"Thank you..." Numabuchi's mother said sadly.

"Auntie, this photo is magical. Can I take it with me?" asked Reiheiji.

“Okay.” Numabuchi’s mother nodded.

Hattori Heiji turned around and found that Lin Xiaofeng had already left the Numabuchi residence. He quickly said goodbye to Numabuchi's mother and caught up with Lin Xiaofeng.

"Lin Jun, why are you in such a hurry?"

"nothing."

Lin Xiaofeng remained expressionless. His current task was to execute the son of the mother of the swamp abyss, so he naturally had no good intentions about staying in the mother of the swamp abyss's house any longer.

"Where do we go next?" Hattori Heiji asked.

"We are looking for Numabuchi Kiichiro," Lin Xiaofeng replied.

“Of course I know I need to find Numabuchi Kiichiro, but the question is, where do I even begin?” Hattori Heiji asked.

"do not know."

"what?"

"Hattori-kun, you're a detective too. Don't always rely on me. Use your own brain."

"let me see……"

Hattori Heiji calmed down and thought about it carefully, and soon came up with a solution.

“I need to contact my dad and issue an arrest warrant for Numabuchi Kiichiro. In addition, I also need to investigate whether my mom and Sakata Yusuke are related to this serial murder case.”

"You're right. However, when the body of the quiet man was dumped, your mother was at home, so Toyama and Kazuha can provide an alibi for her, and she's not a suspect."

Numabuchi Kiichiro has been missing for a long time, and when Noya Yasuto's body was dumped, he should not have been in Osaka.

The prime suspect is actually Yusuke Sakata. He was at the scene when Yasuto Nono's body was dumped.

"It's unbelievable. Yusuke Sakata was an excellent detective. I really can't understand why he would kill the three people in the photo."

"Go back and ask your mom, maybe she knows something."

"Ah."

Hattori Heiji drove Lin Xiaofeng back to Osaka before dark.

Hattori family.

Shizuka Hattori had already prepared dinner and was waiting for her son and his friend to come home.

Kazuha Toyama spent a day in Osaka with Ran and Sonoko before heading home. By the end of the day, the three girls had become good friends, friends who could now call each other by their first names.

"Mom, I'm back."

As soon as Hattori Heiji got home, he went straight to his mother, ignoring his childhood friend who was waiting for him.

"Heiji, what's wrong? Why are you in such a hurry?"

Hattori Shizuka, who had been sitting quietly, stood up and questioned Hattori Heiji.

"Mom, do you remember this photo?"

"photo?"

Hattori Heiji took out the old black-and-white photo and questioned Hattori Shizuka.

Lin Xiaofeng stood aside watching, wanting to know how Hattori Shizuka would respond.

Hattori Shizuka took the photo, thought about it for a while, and then remembered it.

“I remember now, this is a photo of me and other students when I was young, as a driving school student. At that time, I wasn’t married to your father yet. All six people in the photo, including myself, were learning to drive with the same instructor.”

Then, Hattori Shizuka's expression turned regretful.
