Ke Xue: Shinichi and I are childhood friends.

Chapter 1216 The past 7 years ago

Hishinuma Kosuke wanted to make some excuses, but Yuya obviously wouldn't give him a chance.

Yuya pointed at the sink drain and said, "There's still some coffee smell in the sink, even though you flushed it with water."

"Also, we can go to the shop where you bought your coffee and ask the staff there to see if you really bought coffee there when the incident happened today."

As soon as he said this, Hishinuma Haosuke instantly lost all his strength and collapsed to the ground.

His face turned pale, and he murmured in disbelief: "How could it be so easy to be seen through?"

Seeing this situation, how could others not realize that Hishinuma Kosuke was implicitly admitting that he had committed murder?

Uesugi Shoko covered her mouth with her hands and asked in shock, "Hishinuma, did you really kill Genda? Why?"

Hishinuma Kosuke sneered and looked up at Uesugi Shoko: "Do you know how your brother died?"

Guasheng Xiangzi was stunned for a moment: "I, I don't know either."

Katsumata Mizuna suddenly covered her mouth and burst into tears: "Who could have thought that Kinji would commit suicide! He was in great shape during that time, and he even said that he would be promoted soon. We even celebrated in advance."

Yuya asked tentatively, "Um, who is Kinji?"

Uekusa Shoko explained, "Ah, it's my brother, Uekusa Kinji, who is also a Go player. Mizuna was dating my brother before."

Sato Miwako crossed her arms and said, "So, you don't know why he committed suicide?"

Uesugi Shoko nodded. "That's right. All I know is that someone from the Shogi League suddenly came looking for my brother, and not long after that, my brother committed suicide. Then, Kishimoto suddenly became depressed, as if he was still brooding over my brother's death."

Sato Miwako pondered and said, "It seems that there is another reason for your brother's death. It is necessary to find this chess player Kishimoto."

"Tsk!" Hishinuma Haofu suddenly sneered, "No need, he's already been killed by me."

"what?"

Everyone looked at Hishinuma Kosuke in surprise.

Hishinuma Kosuke slumped on the ground, looking up and saying, "You all know it anyway, so there's no need for me to hide it. I killed that Kishimoto guy before coming here. Calculating the time, it's about time now, right?"

"What do you mean?" asked Sato Miwako in confusion.

Hishinuma Haosuke sneered, stood up from the ground, staggered to the balcony, and looked into the distance.

Everyone followed him and looked in the direction of his sight. They saw a black chimney in the distance and black smoke coming out of a house next to it.

"Ah, it has indeed begun."

Miwako Sato was surprised: "It's on fire? Could that be Kishimoto's house?"

"Takagi!"

Takagi Wataru responded loudly and quickly contacted Inspector Yuminaga of the Fire Department.

However, his call seemed a little late, as Inspector Gongchang had already handled the matter on the scene.

After questioning, a charred body was found in the room where the fire broke out. It seemed that the person was undoubtedly Kishimoto.

Guasheng Xiangzi was shocked: "Hingzuma, why did you kill them?"

Hishinuma Kosuke sneered: "It's all their fault. They killed Kinji!"

He slowly explained his motive for the murder.

It turns out that including the already killed Genda Yasukio, Nishikido Koharu, Kishimoto Kumahei, and Uekusa Kinji who committed suicide, all four of them cheated in the shogi game.

They carried pens with tiny cameras in their breast pockets and sent footage of the game to other people's phones.

The other three people would search for the next trick on the Internet, and when they met in the bathroom or corridor, they would tell each other the next trick, allowing the contestants to win continuously.

But falsehood will eventually be exposed.

Kinji Ueokata aroused the suspicion of the Shogi Federation because he went to the bathroom too often and was called in for a talk.

When he asked the other three for help, he was met with a cold response, asking him to abide by the rule of knowing but not speaking.

Before they carried out this cheating act, they had already agreed not to tell the secret.

Once anyone is discovered, he must die to protect others.

Uesugi Kinji was forced into a desperate situation and finally had no choice but to commit suicide.

Hishinuma Kosuke and Uekusa Kinji are good friends. He realized that this matter was not simple. In the end, he found out the secret of the four people's cheating and learned the full truth from the first victim, Nishikido Kimiharu.

In order to avenge his friend, he killed three people, placed a chess board with a missing leg at the scene, and wrote a confession in Kishimoto's tone, intending to hand over the serial killer to Kishimoto Kumahei.

But I didn’t expect that a famous detective would come to today’s exchange meeting and see through his modus operandi at a glance.

on the way back.

Yuya and Haneda Hideyoshi walked in front, while Miyamoto Yumi followed behind with a resentful look on her face.

Conan smiled beside her: "Yumi-sister, why are you so angry?"

Miyamoto Yumi puffed up her cheeks and said, "Kumakichi, what can't I hear? He and Yuya are sneaking around."

Conan's mouth twitched slightly. He didn't know how to explain it, so he just forced a few cute smiles to get away with it.

In front, Yuya and Haneda Hideyoshi were asking about Haneda Hiroshi.

Yuya hinted at his relationship with Shuichi Akai and quickly gained Hideyoshi Haneda's trust - but obviously, Shuichi Akai and his second brother revealed a lot of things, otherwise he would not have believed Yuya's words so easily.

Haneda Hideyoshi also said with a smile that he didn't expect that he and Yuya were related.

Haneda Hideyoshi frowned and said, "It's been seventeen years since the incident. I didn't expect you to ask about it all of a sudden. It seems that Brother Haoji's death was not a simple accident."

However, Haneda Hideyoshi did not ask any more questions and started to tell the story directly.

"Seventeen years ago, Brother Haoji traveled to the United States to participate in an international chess tournament. However, the day before the tournament, he was attacked and killed in the hotel where he was staying."

"Back then, my father was entrusted by my current adoptive father to investigate the truth of the matter. As a result, it seems that he had provoked a powerful enemy, and the situation was extremely critical."

"My mother took me, my older brother, and my younger sister who was still in her belly to seek refuge in Neon."

"Because I have the gift of instantaneous memory and a high talent for shogi, I was adopted by the Haneda family to inherit my brother Hiroshi's unfinished dream."

"After staying in Japan for a while, my eldest brother went to study in the United States. It was ten years later when I saw him again."

Yuya was a little disappointed: "So, you don't know anything about Haneda Hiroshi's case?"

Haneda Hideyoshi shook his head. "Ever since I was adopted by the Haneda family, I've been immersed in shogi. My adoptive parents also kept silent about my father's disappearance. They're probably afraid they'll upset me, right?"

"By the way," Haneda Hideyoshi suddenly thought of something, "How is my eldest brother doing recently?"

Although he had been secretly in contact with Shuichi Akai, they had never actually met.

Given Shuichi Akai's personality, he wouldn't chat about family matters with Hideyoshi Haneda, so he wanted to ask Yuya about his elder brother's situation.

Yuya was stunned for a moment, and the image of Subaru Okiya wearing an apron and busying himself in front of the stove with potato and beef stew appeared in his mind. The corner of his mouth twitched slightly: "Well, he should be living... not badly, right? Quite leisurely, making potato and beef stew in the kitchen when he has nothing to do."

"Beef stew with potatoes?" Haneda Hideyoshi was a little confused, but he immediately laughed: "Is that so? That's good."

The two chatted for a while.

Yuya confirmed that the little girl next to Sera Masumi was their mother.

Because Hideyoshi Haneda said that their mother's original name was Sera Mary.

But he seemed unaware of his mother's shrinking.

Yuya pondered, if the name is real, then what does she mean by calling herself the sister outside the field?
