After careful search by Baiyan Zhenyu and Conan, the newly discovered clues mainly include the following points.

First, some newly worn scars were found at the railing binding and suspending boss Oda's body;

Second, the rope used to hang boss Oda's body is obviously a new rope, but there are many off-line or charred places on it, and a strange armor knot is tied at the end;

Third, there are some stains on the elbow of boss Oda's suit with the smell of grass, which is likely to be contaminated by falling on the grass;

Fourth, the two leather shoes on boss Oda's feet and the heel parts of the shoes are stained with soil;

Fifth, in the grassland more than ten meters away from the quintuple tower, I found the brick inlaid pin of boss ODA.

The above five clues are enough to make people suspect that boss ODA did not commit suicide, but was killed before he could hang on the top of the tower by special means.

"Although we have found these doubts, if we can't solve the method of hanging the body, the police will close the case as suicide."

After Bai yanzhenyu whispered, he turned to Conan and asked, "Conan, do you have any eyebrows?"

"Well, it is."

Conan responded absently. After thinking hard for a while, he suddenly brightened his eyes and said confidently, "brother Zhenyu, I already know the technique used by the prisoner."

Baiyan Zhenyu was not surprised because he knew Conan's ability to solve cases. He immediately asked curiously, "Oh? Who are the prisoners?"

"The prisoner is the village manager. If my reasoning is correct, I will find something there and come with me."

On Conan's leading way, the two came to the ancient well near the quintuple tower, pointed to the wellhead and the nearby lawn, and explained: "look, there are some friction marks on the moss surface of the wellhead, and there is also a trace of a rope turning out from below on the lawn. The Village Manager really killed boss ODA with that technique."

"So, what's the way?" looking at Conan who was playing riddles, Bai Yan Zhenyu couldn't help rolling his eyes at him.

"Don't worry, let's go back first and let uncle Maori tell you later."

Conan smiled and returned to the outside of the quintuple tower with Baiyan Zhenyu. He quietly raised the anesthetic watch on his wrist and was ready to start the daily persecution of Maori Kogoro in the original book.

……

While Maori Kogoro was discussing the case with police officer Henggou, the village manager went over and asked, "police officer Henggou, can I go back to the hotel? The occupation in the hotel must be panic now, and I need to go back to appease them."

Officer Henggou nodded and reminded, "well, you can go, but for the sake of caution, please leave your contact number to me."

"OK, I'll get you a business card."

The village manager took his wallet out of his arms and prepared to take out his business card. As a result, his hand slipped to the ground and revealed a large stack of banknotes.

Maori Kogoro looked at his wallet with bulging eyes and joked: "manager of the village, you also brought so much money. Aren't those all boss Oda's money?"

The village manager picked up his wallet in a panic and said, "don't talk nonsense, Mr. Maori. My wallet is completely different from the president's wallet. The money is reserved for the hotel supplier."

Maori xiaowulang scratched his head and said with an embarrassed smile, "ha ha, I'm kidding."

"Officer Henggou, just call me if you want me."

The village manager didn't worry about this topic. He took a business card out of his wallet and handed it to officer Henggou, so he was ready to leave.

Just then, a transparent anesthetic shot into Maori xiaowulang's neck, making him stagger and sit on the steps outside the quintuple tower.

"Village manager, you can't go."

"Maori Kogoro" hung his head and said, "officer Henggou, I really can't help you. I just hinted at you so many times. Why didn't you notice? This is not a suicide at all. Boss ODA was killed!"

"It's not suicide, Mr. Maori. Please tell us the truth."

Police officer Henggou had already realized that the case was not simple, but he had not found any evidence to prove his murder. After listening to the words of "Maori xiaowulang", he immediately waited excitedly for the reasoning of "Maori xiaowulang".

"No problem," promised Maori Kogoro, and then asked, "but officer Henggou, I need to reproduce the scene of the crime. Can you ask the police who are doing a favor?"

"Of course, we all listen to your arrangement." officer Henggou agreed and took his men to act according to the order of "Maori xiaowulang".

"First, lay a cloth bag of Mr. Hotan's weight flat on the grass and tie the top of the bag with a rope;"

"Then, hang the rope through the tip of the eaves on the fifth floor, tie the rope through the railing from there, and then extend to the ground."

"Finally, tie the extended rope to the iron plate on the ancient well that no one uses. As for these iron plates, put them on a steel bar so that one end can be affected by the rope."

After the police arranged the scene according to the instructions, "Maori xiaowulang" asked someone to give the rope to officer Henggou, smiled and said, "well, officer Henggou, now pull it hard?"

"Oh, OK."

When officer Henggou pulled hard, the reinforcement on the wellhead was pulled away by him, and the heavy iron plates stacked together fell into the well in an instant.

At the same time, under the traction of this huge falling force, the cloth bag connected by the rope soared into the air, and finally hung outside the spire of the fifth floor of the quintuple tower like boss Oda's body.

Henggou officer stared at the slightly shaking cloth bag and exclaimed, "the cloth bag is hanging up, just like Mr. Tian."

"Hehe, do you understand?"

"Maori xiaowulang" smiled and explained: "the reason why there are off-line or charred places on the rope is due to high-speed friction. From the position where the pin fell, it is the first scene of the murder."

Officer Henggou understood this technique and asked, "Mr. Maori, if you want to put the rope around boss Oda's neck, boss ODA will resist, but there is no sign of fighting at the scene?"

"Yes, this is a very basic problem. I'll explain it in order."

Faced with the question raised by police officer Henggou, "Maori xiaowulang" seemed very calm and began to reason in detail about the situation at the time of the crime.
