Ke Xue: The secret was discovered by Xiaolan!

"Big brother, are you the high school detective Lin Yan?"

Ayumi Yoshida pointed at Lin Yan with her index finger, an expression of excitement and surprise on her face.

"That's right, I'm Lin Yan. "

Lin Yan gently patted Ayumi Yoshida's little head.

"Ayumi, is he famous?".

Kojima Motota came to Ayumi Yoshida and looked at Lin Yan with puzzled eyes.

"Of course it's famous, my mom is a big brother fan. "

Ayumi Yoshida patiently explained to Motota Kojima.

"What are the fans?".

"Is it okay to eat?".

Motota Kojima touched his head and said suspiciously.

"Stupid, fans are almost star chasers!".

"You can't eat it. "

Mitsuhiko Tsuburaya patted Motota Kojima on the shoulder and explained to Motota Kojima.

"Big brother, I remember we haven't met before, how do you know us?".

Ayumi Yoshida looked at Lin Yan curiously and asked.

"While in line just now, I saw a couple of you sneaking in through the sewers. "

Lin Yan explained to Ayumi Yoshida.

Hearing this, Ayumi Yoshida and the others were suddenly a little embarrassed.

"Did you see anything falling down here just now?"

Lin Yan looked at Ayumi Yoshida and the others curiously.

"Big brother, we just heard something falling down over there. "

"It's so dark that we didn't go to see it. "

Ayumi Yoshida pointed in the direction in the distance and began to say to Lin Yan.

"Little sister, thank you. "

Lin Yan thanked Ayumi Yoshida.

"Big brother, can you give me an autograph?"

"My mom is a fan of yours and I want to surprise her. "

Ayumi Yoshida took out a pen and a small notebook from her clothes and proposed to Lin Yan.

Looking at Ayumi Yoshida's well-behaved and cute appearance, Lin Yan couldn't bear to refuse.

"No problem. "

Lin Yan took the pen and notebook from Ayumi Yoshida's hand.

Lin Yan flipped through the small notebook and saw that on this small notebook, Ayumi Yoshida recorded a lot of interesting things.

Lin Yan wrote his signature on a new page.

"Here you go. "

Lin Yan then handed the small notebook to Ayumi Yoshida.

"Big brother, thank you. "

Ayumi Yoshida took this small notebook as a treasure and was very happy.

"Xiaolan, you leave here with these children. "

Lin Yan said to Mao Lilan.

"Okay. "

Maolilan nodded and agreed.

"Kid, there's a murder here, come out of here with me!".

Maolilan's tone is very gentle, which makes people can't help but feel good.

"Okay. "

Ayumi Yoshida and the others nodded and followed Mao Liran out of here.

Lin Yan walked in the direction that Ayumi was pointing.

In that place, Lin Yan found some fallen pearls, piano strings with iron hooks, and Kishida's head, which had fallen inhumanly.

Lin Yan wore gloves and collected some piano threads with pearls and iron hooks.

Kishida's head, Lin Yan did not move.

A few minutes after Lin Yan left, Kudo Shinichi found the place.

Kudo Shinichi didn't meet Ayumi Yoshida, and the time to find clues was a few minutes slower.

Lin Yan and Kudo Shinichi entered from the opposite direction of the tunnel and just didn't encounter each other.

......

When Lin Yan came out of the tunnel, Officer Twilight had already arrived.

"Brother Lin Yan, I feel relieved to see you here. "

Officer Twilight was still worried about how to solve this case, but when he saw Lin Yan here, his heart suddenly felt a lot easier.

In the past year, Lin Yan has helped Officer Twilight solve many cases.

"Don't worry, Officer Twilight, I've already investigated this matter. "

Lin Yan said confidently to Officer Mudu.

"Officer Twilight, in Ms. Aiko's bag, found a bloody murder weapon. "

Miwako Sato looked at Aiko vigilantly to prevent Aiko from breaking out and hurting people.

"No, I'm not a murderer. "

Aiko was in a very flustered mood, she didn't expect things to be like this.

"Brother Lin Yan, it seems that there is no need for you to appear today. "

"The killer has been found!".

Officer Twilight patted Lin Yan's arm and proudly showed off to Lin Yan.

Officer Twilight thought to himself, "My subordinates still have capable people, even if they don't rely on detectives, they can solve the case quickly." "

"I'm really not a murderer, and I don't know how this dagger ended up in my bag!".

"Please believe me!"

Aiko was even more flustered and defended herself.

Most of the people present didn't believe Aiko, and they all felt that Aiko was the murderer.

"The murderer is this woman, arrest her. "

Gin didn't want to waste too much time here, and said to the police with a blank face.

"Aiko, why did you kill Kishida?".

"Isn't your relationship very good?".

Reiko subconsciously stayed away from Aiko and said suspiciously.

Aiko was a little desperate at this point, and she didn't know how to prove her innocence.

It was at this time that Aiko saw Lin Yan.

"Lin Yan, you promised me before to help me find out the murderer of Kishida. "

"I know you're a great detective, and now you're the only one who can help me!".

Aiko is like a person who has fallen into the water grasping a life-saving straw and sees Lin Yan as her last hope.

"Ms. Aiko, don't worry, I will never go back on what I promised. "

Lin Yan smiled confidently at Aiko.

Seeing Lin Yan's smile calmed Aiko's heart a lot, and at this moment, Aiko felt that the million yen was worth it.

"Officer Twilight, the person who killed Mr. Kishida was not Miss Aiko. "

Lin Yan stood up and began to speak to Officer Twilight.

Hearing this, Aiko suddenly breathed a sigh of relief in her heart.

The feeling of being doubted by everyone just now was too embarrassing.

Hitomi had a shocked expression in her eyes, and she had a bad premonition in her heart.

Xiao Hitomi thought to herself, "Lin Yan can't already know the truth of the matter, right?"

Officer Twilight still believes in Lin Yan's ability.

"Ms. Aiko is not a murderer, so who is the murderer?".

Officer Twilight looked at Lin Yan curiously, now he had no clue.

"The murderer is Ms. Hitomi-chan. "

Lin Yan pointed at Xiao Tong, and his tone was very firm.

"It can't be. "

"Hitomi can't be a murderer, you must be mistaken. "

"On the roller coaster just now, Hitomi sat in the first row, and Mr. Kishida sat in the third row. "

"On a speeding roller coaster, it's impossible for Hitomi to kill Mr. Kishida. "

Reiko stood beside Hitomi and explained to Hitomi.

"I didn't kill Kishida, you're mistaken. "

Hitomi was very nervous, but she still pretended to be calm and said.

"Lin Yan, these two ladies are right. "

"It's impossible for Ms. Kotomi to kill Kishida. "

Officer Twilight also begins to speak for Hitomi, who also thinks that Hitomi can't be the murderer.
