Great Swordsman Ke Xue.

Chapter 543 Seeking the enemy in the void
The detectives knew very well what the lack of any poison residue in the beverage cup meant. Not only did Shimizu Koji lose his status as a suspect, but the case was also completely out of control.

There is no poison in the drink, so where is the poison? !

"Inspector Megure?! Then, where was the poison found?!"

Kudo Shinichi couldn't help but ask first, and Mori Kogoro and Hattori Heiji followed closely behind, and the pressure instantly fell on Inspector Megure.

Inspector Megure didn't expect that one problem would be solved before another one arose. Why are these guys so annoying?
Being watched by many people, Officer Megure's expression gradually became a little embarrassed. "Well, according to the feedback from the forensic personnel, it seems that no traces of poison have been found so far."

The expressions of Kudo Shinichi and Hattori Heiji were as if they were struck by lightning, and Shimizu Koji was almost taken away just now, and Kazuha was misunderstood, but neither of them showed such expressions.

Koji Shimizu frowned slightly, and glanced at the somewhat nervous Mai Hongjo inconspicuously, but suddenly a sentence that he didn't pay much attention to just now flashed through his mind.

"I put the poison in the ice."

Before, he only cared about the reason why Hong Shang Mai killed people. As for the method of poisoning she explained, Shimizu Koji didn't pay much attention to it. Now that he thought about it, he suddenly discovered
interesting.

It seems that he was too anxious and hid the liquid poison in the ice. Although Koji Shimizu thought this was a bit far-fetched, it was not impossible to succeed, and it was already a successful case.

Thinking of this, Shimizu Koji's eyes flashed, and he took the initiative to step forward, "In this case, I should be clear of suspicion. However, if the murderer did not use the drink, how did he poison it?"

"Officer Megure, the poison is potassium cyanide, right?"

"Ah, yes, what's wrong, brother Shimizu?!" Inspector Megure looked faintly expectant.

But Koji Shimizu did not do as he thought. He did not start to solve the problem like his younger brothers Kudo or Mori.

"If I remember correctly, cyanide poisons are fast-acting and are one of the fastest-acting poisons that can kill people. This can rule out the possibility that Mr. Urata was poisoned outside of school."

Everyone held their breath and looked at Shimizu Koji quietly, and Mai Hongjo in the crowd couldn't help but become nervous. She couldn't understand why Shimizu Koji was doing this.

She couldn't help but wonder if this strange boy, Shimizu Koji, had changed his mind and was planning to expose her identity.
Seeing that most people were aroused, Shimizu Koji smiled and turned around and said, "Conan, how long does it take for cyanide poisons to take effect?"

After hiding in the crowd for a long time, Haibara Ai, who was happy to be free, raised her eyebrows when she heard the words and walked out silently. At this time, many people noticed that Conan, who usually ran around, was so well-behaved today.

This was also Shimizu Koji's little idea. In order to solve the problem once and for all and avoid being suspected by Xiaolan later, he called out Haibara at the last minute.

Just now, when Koji Shimizu went to talk to Mai Hongo, although he didn't bring her directly with him, she followed him, but Mai Hongo didn't notice it.

When Ai Haibara learned of Shimizu Koji's plan, she did not raise any objections in the end, which made Shimizu Koji happy. At least his family Shiho was not a foolish person who blindly believed in laws and justice. However, considering Ai Haibara's growth experience in the organization and what he had seen and heard in the past six months, it was completely predictable that she would make such a choice.

"Potassium cyanide is a highly toxic drug. If an average person takes 50 mg, they will die. This process usually only takes a few minutes, so even if it is discovered, it is too late to provide emergency treatment."

"But this type of drug is difficult for ordinary people to make, and even if they buy it, it is difficult to buy it directly."

Haibara Ai probably guessed what Shimizu Koji was going to say, because Shimizu Koji had told her before that after he went to the Metropolitan Police Department, he would put the blame on the crime to an unknown killer.

Anyway, without evidence, it’s not up to them to decide.

Although it was the first time that Haibara Ai helped to cover up the truth, she had no objection because not only herself but also her sister. If they really accepted the so-called legal sanctions, they would probably have to die many times. Even if Japan did not have the death penalty, they would still be sentenced to hundreds of years in prison.

A group of adults, as well as students who were still watching nearby, all cast curious glances at Conan, who was transformed by Haibara Ai. Haibara Ai was not at all stage-frightened, and directly ignored Kudo Shinichi's constant winking at her. She just paused for a moment, and continued in a cold voice:
"So, generally speaking, this drug is used to kill people. In addition to fully prepared murders, there is also a special situation where people hire someone to kill someone."

Hiring a killer?!

This word is both familiar and unfamiliar to these detectives. What is familiar is that such things are not uncommon, but what is unfamiliar is that they have hardly ever encountered such a situation. They usually only deal with the police, victims, and murderers. As for the killer, it cannot be said that they have never heard of it, but they have never seen it either.

"Hey, hey, hey! Conan! Where are you from——"

"It was me, Officer Megure. I told him. This kid just asked me these questions out of curiosity. Haha."

Before Inspector Megure could finish being surprised, Kudo Shinichi came to his senses and quickly stood up. However, as he spoke, he subconsciously walked over and wanted to touch Conan's head. This seemed normal to outsiders, but Haibara Ai swung her hand and directly knocked Kudo Shinichi's hand aside.

Fortunately, no one paid attention to such details, and Kudo Shinichi was embarrassed for a second but then recovered.

His explanation successfully made everyone present start to think: Is it really possible to hire someone to kill someone?
Hattori Heiji and Maori Kogoro were still a little reluctant to accept the detective's intuition. Maori Kogoro was also a little serious today. After all, it was his daughter's drama performance that was ruined. Uh, although -

Well, good destruction!
"So, this incident is most likely a murder for hire?" Inspector Megure said to himself.

And Shimizu Koji immediately followed up and said, "This is just a guess, but Officer Megure, you can ask the forensic personnel to check the body again to see if there are any scars like pinholes. If there are, then it is very likely."

After Shimizu Koji said this, no matter what the detectives thought, the matter seemed to be settled. Even Kudo Shinichi began to believe it if such a wound was really found.

Of course, such a wound existed. When Koji Shimizu walked back to the scene and passed by the corpse, he had already made arrangements.
