"Conan, turn the words Guchuan University 90 degrees clockwise and look again."

Reminded by Bai Yan Zhenyu, Conan turned the piece of paper transcribed the campaign advertisement horizontally, looked at the words "only three leaves" on it, and suddenly realized: "Guchuan University actually refers to Da only three leaves."

"Yes, I didn't expect it... Conan, look here."

Bai yanzhenyu sighed. Unexpectedly, when he squatted down to check whether the rope was fastened firmly, he accidentally found a circular scorch mark on the railing, and there were traces of paint falling off near the scorch mark. He quickly asked Conan to come and watch.

"Strange... Wait, don't you say..."

Conan watched carefully for a while. He seemed to think of something. He turned his head and ran to the place where the gun sound came from, and carefully looked at the railings in the nearby area.

When Conan found that there were similar traces on some railings, his face showed a clear color and said with a confident smile: "I see. In this way, we can control the time and everyone's actions. No wonder he wanted to find the detective of the service department to come here."

Just as Baiyan Zhenyu was about to ask Conan what he knew, a tennis ball flew from behind and hit Conan on the head.

Baiyan Zhenyu and Conan looked around and found Xiaolan's face with a slightly angry expression coming from the far direction.

After arriving at the two, Xiao Lan complained discontentedly: "Conan, why do you love to run around so much? It scares people every time, and brother Zhenyu. It's not very safe outside. How did you bring Conan out?"

"Sorry."

Baiyan Zhenyu and Conan looked at each other, resolutely apologized to Xiaolan, and then followed Xiaolan back to the restaurant.

On the way back, Bai Yan Zhenyu asked curiously, "Xiaolan, where did you get that tennis ball?"

While walking with Conan, Xiao Lan explained, "this is tennis. I found it under a table when I was looking for Conan in the restaurant. I also asked who it is. Everyone said they didn't know."

Conan pushed the glasses on the bridge of his nose, pretending to be naive and asked, "sister Xiaolan, uncle shazaki, what did he say when he saw the ball?"

"No," Xiao Lan shook her head and replied, "before I showed it to him, he went to the bow with his father. At the same time, they shouted and said that a gunshot wound from a long time ago was found on Mr. Xijiang's shoulder blade."

Hearing this, Conan's pupils narrowed and asked eagerly, "Uncle Maori, where were the others when they left the restaurant in order to find the man named da caisan?"

Looking back, Xiao Lan replied, "everyone is in different places, but they all came back when Dad returned to the restaurant."

"I see. I know the whole story now..."

Conan's mouth made a radian, then quietly fell behind and told Bai yanzhenyu the result of his reasoning.

"Unexpectedly, the murderer turned out to be him. It's really like..."

After hearing Conan's reasoning, Bai yanzhenyu suddenly showed an expression of enlightenment. Then he returned to the restaurant with Xiaolan and gathered the people together to expose the real murderer according to Conan's plan.

……

In the restaurant, Ji Beizhu lit a lady's cigarette, took a sip and asked suspiciously, "brother Baiyan, have you really solved the case?"

Baiyan Zhenyu nodded and admitted, "yes, I have solved the truth of the whole case."

Group leader shaizaki frowned slightly, pointed to the body of Xijiang Shijiu in the bow of the boat and said in surprise: "you shouldn't tell us that the murderer wasn't Xijiang Shijiu?"

"No, the killer is really Xijiang Shijiu. That's right."

Bai Yan Zhenyu smiled and explained: "he did, as we had guessed before, hide on the ship after pretending to be dead at the beginning, in order to wait for the opportunity to kill. What he wanted to kill was Mr. whale well."

Ji Beizhu looked at Bai Yan Zhenyu meaningfully and asked, "tell me, who was the person who was burned to death?"

"That man is Mr. Kameda."

Baiyan Zhenyu's tone was very positive and explained: "at the beginning, Xijiang first asked Mr. kuota out to kill, and then put his body in the box at the stern of the ship."

"Then he went back to everyone, lit a fire and burned the flag on the mast. When we all ran to the deck to check the situation, he burned the box."

"When he put Mr. Kuroda into the box, he didn't put on clothes for him immediately because he wanted to wait for Mr. chimazaki to give up looking for the mysterious old man Dacai San. If he helped him put on clothes, it would take a lot of time and be easily exposed."

After hearing Bai Yan Zhenyu's explanation, the people fell into meditation, and then leader shazaki, who valued the evidence, asked, "do you have any evidence for that?"

"The burnt corpse's arms will be placed on both sides of his cheeks, which is the best proof, because when placing the corpse, if you can straighten your hands upward, even if the corpse becomes stiff after death, it will be much more convenient to wear clothes."

"As for his watch, the band will come loose because Crab River's watch can't completely match Mr. KuoDa's wrist."

"Before the ignition, Crab River asked Mr. Jingjing to meet at the stern of the ship. If it goes well, you can slander him as the murderer. After all, the people who appeared at the scene of the murder before the crime will always be the first to be suspected."

Ji Beizhu didn't quite believe Bai Yan Zhenyu's explanation. He asked, "well, why did he deliberately make everyone think he was dead?"

Baiyan Zhenyu glanced at Ji Beizhu and said inexplicably, "this is to make him feel scared at the first time when he appears in front of the next target, Mr. Jingjing, because after all, he betrayed his brother twenty years ago."

After hearing this, Ji Beizhu was silent. Maoli xiaowulang asked, "Zhenyu, who is the old man named Dacai San?"

Baiyan Zhenyu took his eyes back from Ji Beizhu and replied, "that's a false identity created by the murderer to scare people. There is no such person at all. You can see the scars on the chest of Xijiang, which can prove that he is Dacai San, the dark shadow planner who was thought to have been buried at the bottom of the sea 20 years ago!"

"It's impossible. Don't talk nonsense. This man can't be Dacai San..."

Hearing Bai yanzhenyu's reasoning, Ji Beizhu suddenly stood up, trembled slightly and told a secret.
