After rejecting me, Fei Yingli regretted it

"So who will it be? Who will be the murderer who poisoned the president with this technique? After

Qin Xiao said the murderer's modus operandi, he only had to say his name.

And Twilight Thirteen was like listening to a story, urging Qin Xiao to tell the finale.

"It's the Miss Takako Fujii who is closest to the gas switch after the crime, and the murderer of President Hida is you!"

After hearing Qin Xiao's words, Nanzawa Naozen and Iinohiro, who were still standing next to Fujii Takako, immediately bounced away.

After all, no matter how bold he is, a murderer still feels panicked standing around.

"Because before you leave the company, you put the kettle on top of the gas stove and then light the fire."

"When President Hida was halfway through counting the money, the sound of the kettle boiling suddenly sounded, and he would run out to turn off the gas stove."

"Originally, you planned to wipe off the poison when you went to work tomorrow."

"But the body was found sooner than you expected, and the police arrived here."

"So you think that if you continue to consume like this, the poison left on the gas furnace switch will be discovered sooner or later."

"You ran to the toilet and wiped off the poison from the gas switch with a handkerchief."

Qin Xiao's words did not make Takako Fujii feel a little flustered.

Instead, he calmly took out a cigarette from his pocket and lit it.

"Aren't you talking nonsense? Didn't Officer Twilight already say that that poison can't be wiped off in a short time.

After saying this, Takako Fujii spat out a puff of smoke, looking confident.

Qin Xiao could tell from her calm appearance that this was a woman with extremely strong psychological quality.

If you change to an ordinary person, you may no longer be able to bear the pressure and show flaws.

However, the case was over, when Qin Xiao said these things.

"You're right, it's really impossible to do this with an ordinary handkerchief."

"Officer Twilight, where is the iodine wine I just asked you to take?"

Qin Xiao set his gaze on Twilight Thirteen on the side.

"Oooh! In this police officer Qin Xiao.

As soon as he heard Qin Xiao's words, Twilight Thirteen immediately handed him the iodine wine he had held in his hand.

But Qin Xiao did not take it.

"Officer Twilight, can you please drop iodine wine on Miss Fujii's handkerchief?"

"As long as a drop of iodine wine is dropped, the whole case will be revealed."

Twilight nodded after hearing this.

"Miss Fujii, please give me the handkerchief you just used."

Twilight Thirteen held out her hand in front of Takako Fujii.

Takako Fujii didn't say anything, and very cooperatively handed her handkerchief to Twilight XIII.

After getting Takako Fujii's handkerchief, Twilight spread it out and placed it on the table.

"Hey! Wouldn't dropping this iodine wine on this handkerchief turn coffee-colored?

Twilight glanced at the iodine wine in his hand and muttered.

However, after saying this, Twilight thirteen dripped a drop of iodine wine on the handkerchief.

Then something magical happened.

Takako Fujii's handkerchief immediately turned coffee the moment it touched the wine.

But soon that color disappeared.

"Hmm! How did the color disappear?

Twilight wiped her eyes in disbelief, and then widened her eyes, afraid that she had seen it wrong.

"That's right, Officer Twilight, you're not mistaken. Because the sticking on Miss Fujii's handkerchief was not sweat or water at all, but sodium sulfide sulfate. "

[I really learned mathematics, physics and chemistry, and I don't have to be afraid to go all over the world!] Speaking

of this, Qin Xiao couldn't help but sigh in his heart.

"Sulfuric acid sulfide?"

Twilight Thirteen looked at Qin Xiao in surprise.

"Officer Twilight, the iodine wine you brought is used to remove the bleach of the color of the disinfectant."

"And this is also an antidote that can remove the toxicity of potassium hydrate."

"Conan just went to the bathroom to see it, and this bleach is still in the cupboard."

"That is, at room temperature, it is still a bleach with a special composition that can work."

As soon as Qin Xiao's words were finished, Twilight Thirteen activated his elder brother's fruit's ability.

"Brother Takagi! You hurry up and find this out.

Takagi, who was suddenly called, nodded and ran towards the bathroom.

"After Miss Fujii was discovered in this case, she immediately went into the bathroom when she returned here."

"After the handkerchief is dripped with bleach, the poison applied to the gas switch is wiped off."

At this time, after listening to Qin Xiao's full analysis, Fujii Takako's face immediately became ugly.

The cigarette in her mouth, the filter was about to be bitten off by her.

But her face soon changed back to its original form, and after taking a deep breath of smoke, Takako Fujii covered her head and shook her head.

"It's nerve-wracking! I didn't expect to be exposed so quickly.

After hearing her words, Iinohiro looked at her in disbelief.

"Miss Fujii, you! Is it really you?

"That's right! I killed the hateful miser in Hida.

Takako Fujii smiled dashingly, as if it was a trivial matter for her to kill Hida Manhiro.

"But why?"

Iinohiro really couldn't think of what was going on between Hida Mitsuhiro and Fujii Takako.

"My boyfriend once borrowed money from him, but because he couldn't pay it, he hanged himself."

"How is it simple, isn't it?"

Takako Fujii spread her hands, and then looked at everyone.

"But don't you usually tell us that there is something wrong with the person who borrowed the money?"

Nanzawa Shang asked puzzled.

"That's right, if he borrowed money to buy a car, a house, or gamble, I would never retaliate for him."

"But the most helpless thing is that he went to borrow money for me."

"For you?"

"I had a bad heart before, and I was treated in the hospital until I graduated from college until three years ago."

"My parents died a long time ago, and I don't have any good friends as a personality, and he is the only one who will visit me over the years."

"Every time he came, he would tell me that he would figure out the cost of hospitalization."

"When I got better and arrived at his apartment, I found that he had hanged himself, and he happened to have a loan book from Fatian Finance at his feet."

"Then you came here to take revenge?"

"That's right, I've been waiting for an opportunity to take revenge."

Takako Fujii sighed deeply.
