Hearing the word "killing" from Kudo's mouth with his own ears, Mao Lilan's eyes couldn't help but widen:

"Did they really kill Uchida-san?!"

But Kudo motioned to her not to show excitement with his eyes, and then whispered in her ear:

"Now I just have a conjecture, and I can't be completely sure yet."

"Don't act rashly just yet, and don't get into a conflict with those two guys."

"Wait until I dig deeper..."

"Only by finding more clues can I confirm this conjecture."

With that, Kudo pretended to be calm, and quickly pulled Mao Lilan away from the two bullies.

Mao Lilan glanced at Ishikawa, who was still unashamed, with a slight reluctance, and turned to Kudo and said:

"Shinichi... How do I investigate? ”

"Can I help?"

Even if she didn't move her fist, she instinctively wanted to contribute to the case.

"Don't worry." Kudo Shinichi said confidently, "Just leave it to me next." ”

Speaking, without hesitation...

He turned around and slowly approached the old fire ladder in the alley, welded to the outside of the department store wall.

"Hey... Y-What are you running there for? ”

As soon as he saw Kudo Shinichi approaching the fire ladder, Ishikawa's face immediately changed slightly.

With a gloomy face, he said with a grim face:

"This, this is the scene of the crime, don't run around."

"Oh?"

Kudo Shinichi's footsteps did not stop at all:

"I can't see it..."

"As a delinquent teenager, do you still have this kind of consciousness to help the police take care of the scene?"

"But didn't Uchida-san commit suicide?"

may have been educated by Shiho Miyano before, and this great detective has learned to be yin and yang:

"This kind of suicide scene where there is no suspense at all, I won't have any problems walking around, right?"

"......" Ishikawa choked hard.

His face stiffened as he tried to say something, but finally he stood there without saying a word.

Kudo, on the other hand, stepped on the fire ladder without looking back and began to climb up the stairs.

The iron ladder has been rusted to the point that it is not in shape.

With your feet on the steps, you can hear the terrifying trembling sound of the iron ladder with every step you take up.

And the rusty guardrail handrail is even more unusable, and if you use your hand to support it, it will staggering as if it will fall down at any time.

"Shinichi!"

Maolilan shouted worriedly.

Speaking of which, when she and Shinichi were traveling in New York, they once saved a guy who almost fell to his death because the guardrail fell off on this dilapidated fire ladder.

After such a thrilling experience, she was naturally a little uneasy about Kudo, who rashly climbed the iron ladder.

But Shinichi Kudo is still firmly moving upward, and his eyes are only focused.

Finally, he climbed to the top of the fire staircase.

The department store has a total of six floors, and this fire staircase was only built to the height of four floors.

After climbing to the fourth floor, Kudo Shinichi tried to touch the iron door that opened on the outer wall of the building:

"Sure enough, the door was completely rusted."

"You can't get inside the building from here."

He rubbed his chin thoughtfully, then lowered his head again, searching the small platform at the top of the iron ladder.

But Kudo didn't find anything here.

He only had a close-up look at the gap in the guardrail.

After a slight comparison of length and shape, he was more sure that the section of guardrail that had fallen next to the corpse had fallen from here.

"There aren't enough clues..."

"Looks like we'll have to look somewhere else."

Thinking of this, Kudo Shinichi quickly walked down the stairs and returned to the ground of the alley.

And his investigative behavior further aroused Ishikawa's concern:

"Hey, hey... Stinky boy, can you stop in moderation? ”

"Don't run around the scene of death, do you think you're some kind of detective?"

Ishikawa scolded Kudo Shinichi viciously.

But Kudo laughed softly instead:

"Your instincts are accurate."

"I'm a detective..."

"Shinichi Kudo from Teidan Middle School, have you heard of it?"

"Gong, Kudo Shinichi?"

Hearing the name, Ishikawa's face turned a little green.

Aoki, who had been bowing his head and not saying a word, raised his head suddenly, his face extremely pale:

"You're the famous high school detective?"

"Well, that's right."

Shinichi Kudo nodded seriously and smiled kindly.

Ishikawa and Aoki: "......"

The corners of their mouths were simmering and speechless, and their expressions were extremely wonderful.

Kudo Shinichi ignored them, but turned his head directly to look at Lin Shinichi:

Lin Xinyi was still squatting next to the deceased, carefully observing the various scars on the surface of the corpse.

"Mr. Lin Xinyi."

Kudo Shinichi asked Lin Shinichi directly, who had just come into contact with the corpse:

"What was the temperature of the deceased's body? Is there any heat? ”

"Oh?" Lin Xin raised his eyebrows.

He knew that although the way to find the problem might be different, the great detective must have noticed that something was wrong.

Asking about the temperature of the corpse is actually asking about the time of death.

If the deceased had just jumped to his death as they saw, and the body was still fresh, there would definitely be residual warmth on the corpse surface.

And if the deceased was thrown down from the upper floor after death and has been dead for more than a period of time, the heat from the corpse's surface will quickly escape into the environment and there will be no warm feeling to the touch.

But this is actually the basic impression that most people have of corpse temperature.

The real picture tends to be different:

"The body of the deceased is still hot, and the body surface is still warm."

"But it's summer, it's not sunset yet, and the ambient temperature is relatively high."

Unlike the dawn of the first meeting with Kudo, Tokyo is still relatively hot now:

"The higher the ambient temperature, the slower the corpse temperature drops."

"And when the temperature of the corpse drops to the same level as the ambient temperature, the temperature barely drops again."

"The current ambient temperature is not much lower than the temperature of the human body, so if you only start from the residual heat of the corpse surface that you feel by touch, you can't accurately judge the time of death of the deceased."

And Kudo Shinichi quickly caught the overtones in his words:

"In other words, the deceased doesn't have to be the one who just died?"

"It can be understood that way."

Lin Xin nodded, and as he spoke, he was about to tell his discovery:

"Actually, I've been..."

Before he finished speaking, Kudo Shinichi directly interrupted him:

"I see!"

I don't know what he understood.

He turned around directly, and said confidently:

"Mr. Lin, the scene will be handed over to you to protect."

"I'll go to the department store next door first."

"Uh..." Lin Xinyi's expression was subtle and he wanted to say something.

But Kudo Shinichi was already hurrying out as if he was participating in a race against someone.

"Wait!" Ishikawa's eyes flickered for a while, and he followed tightly: "I, I'll go with you." ”

"You're coming along?"

Kudo Shinichi's tone was very meaningful.

"That's right," Ishikawa said stiffly, "I... I'm also interested in detectives and want to see how you do it. ”

"Okay, it's no problem for you to follow along."

Shinichi Kudo shrugged his shoulders and said he had no opinion at all.

He continued walking, and Ishikawa followed him with a stiff face.

"That's... Shinichi, I'll go too!"

Looking at Ishikawa's muscular and burly body, Mao Liran also hurriedly followed.

She can't rest assured that this bullie, who is suspected of being a murderer, will follow Shinichi.

In this way, led by Shinichi Kudo, the three of them left this quiet alley together.

And before getting out of the alley completely...

Kudo Shinichi suddenly stopped at the entrance of the alley, turned his head, and said to Lin Shinichi with blazing eyes:

"Mr. Lin Xinyi."

"It's a bit bad to say that, but this time... Maybe it's our chance to compete again. ”

Lin Xinyi: "......"

He's not like he's competitive with people in this kind of thing.

But Kudo Shinichi has quietly immersed himself in this excitement of facing challenges:

"Let's take this opportunity to divide the ranks."

"I use my investigative methods, you use yours, to see who can find the truth of this case first."

"That..."Lin Xin stopped when he wanted to speak.

And the great detective Kudo has disappeared at the end of the alley without looking back:

"I'll investigate first."

Ishikawa and Mao Liran left with them, and only Lin Shinichi was left in the alley, Shiho Miyano, who was watching the play quietly, and Aoki, who was so nervous that he began to tremble.

"Hmm..."

"Forget it, it's better for him to investigate more."

Looking at Kudo's high-spirited back, Lin Xinyi's expression was a little subtle:

"But then again, there's nothing to compete with."

"This simple case... Look at the corpse and it will be broken? ”

He muttered to himself, his tone was very helpless.

Then, Lin Xinyi stood up from the corpse and said calmly:

"Aoki-san."

"Huh?" Suddenly being named, Aoki couldn't help but snort violently.

He raised his head and saw Lin Xinyi staring at him with a gaze as sharp as a knife:

"Is this mentality still dead?"

"Don't pretend, come to me and confess your sins."
