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

"Did they really kill Uchida-san?!"

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

"Now I just have a guess, I'm not completely sure yet."

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

"Wait until I investigate further..."

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

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

Mao Lilan glanced at Ishikawa, who still looked unashamed, with a hint of reluctance, then turned to Kudo and said:

"Shinichi...how to investigate?"

"Can I help?"

Even if she doesn't use her fists, she instinctively wants to contribute to the case.

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

Said without hesitation...

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

"Hey...you, what are you doing there?"

As soon as he saw Kudo Shinichi approaching the fire escape, Ishikawa's expression changed slightly.

He said with a gloomy face and a stern look:

"This, this is a crime scene, please don't run around."

"oh?"

Kudo Shinichi’s footsteps did not stop at all:

"I really can't tell..."

"As a bad boy, do you still have the consciousness to help the police guard the scene?"

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

Perhaps because he was taught by Miyano Shiho before, this great detective has learned the strangeness of yin and yang:

"There's no suspense in this kind of suicide scene, so there won't be any problem if I just walk around, right?"

"..." Ishikawa choked hard.

He looked stiff and wanted to say something, but in the end he stood there hesitant to speak.

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

The iron ladder has been rusted into disgrace.

When you step on the steps, you can hear the frightening trembling sound of the iron ladder every time you take a step up.

The rusty handrail of the guardrail was even more unusable. It seemed like it would fall down at any time if I used my hand to support it.

"Shinichi!"

Mao Lilan shouted worriedly.

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

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

But Kudo Shinichi was still moving upward resolutely, with only concentration in his eyes.

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

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

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

"Sure enough, this door is completely rusted."

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

He gently rubbed his chin thoughtfully, then lowered his head and searched carefully on the small platform at the top of the iron ladder.

But Kudo didn't find anything here.

He just observed the guardrail gap here from a close distance.

After a little comparison of the length and shape, he was more certain that the guardrail that fell next to the body fell off from here.

"Not enough clues..."

"It seems I have to look elsewhere."

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

And his investigative behavior further aroused Ishikawa's attention:

"Hey... brat, can you please stop this??"

"Don't run around the death scene. Do you think you are some kind of detective?"

Ishikawa scolded Kudo Shinichi so fiercely.

But Kudo actually laughed softly:

"Your intuition is very accurate."

"I am indeed a detective..."

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

"Kudo Shinichi?"

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

Aoki, who had been keeping his head down and silent, suddenly raised his head, his face extremely pale:

"Are you the famous high school detective?"

"Well, that's right."

Kudo Shinichi nodded seriously and smiled kindly.

Ishikawa, Aoki: "......"

The two of them were mumbling and speechless, and their expressions were extremely wonderful.

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

Lin Xinyi was still squatting next to the deceased, carefully observing the various scars on the body's surface.

"Mr. Lin Xinyi."

Kudo Shinichi asked directly to Lin Shinichi, who had just touched the corpse:

"What is the surface temperature of the deceased's body? Is it hot?"

"Oh?" Lin Xinyi raised an eyebrow.

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

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

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

And if the deceased was thrown from a building after death, or has been dead for more than a period of time, the heat on the surface of the body will quickly escape into the environment, and it will not feel warm to the touch.

But this is actually most people’s basic impression of corpse temperature.

The reality is often different:

"The corpse of the deceased is still hot, and there is residual warmth on the surface of the corpse."

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

Unlike the dawn when I first met Kudo, Tokyo is still relatively hot now:

"The higher the ambient temperature, the slower the body temperature decreases."

"And when the body temperature drops to the same level as the ambient temperature, the temperature will almost never drop again."

"The current ambient temperature is not much lower than the human body temperature. Therefore, it is impossible to accurately judge the time of death of the deceased if we only rely on the residual heat felt by touching the corpse surface."

And Kudo Shinichi quickly caught the implication in his words:

"In other words, the deceased may not have died just now?"

"That's understandable."

Lin Xin nodded, and as he spoke, he was ready to share his findings:

"Actually, I have already..."
