The bright light instantly filled the whole room, and the crowd downstairs gradually dissipated.

Xin Chen found Lin Fan's deep eyes for the first time, and she brushed the broken hair next to her ears, "Is it that cigarette?" Smoke is poisonous? ”

"It shouldn't be, think about it, that cigarette was handed to Zheng Bin by Wu Xing himself, their plan is cautious everywhere, and they will definitely try to avoid exposing themselves, after all, it is very risky to do so, and the cigarette is pre-coated with cyanide, chemicals, and substances, it is not 100% guaranteed that Zheng Bin can smoke that one, because I noticed that the pack of cigarettes has been placed on the coffee table, and they all take cigarettes from it, there are too many uncontrollable factors in this method, so it should not be their best choice, they must choose one that others are difficult to detect, But a foolproof approach. ”

"What's that method?" Xin Chen followed Lin Fan back to the living room.

"Have you noticed that Zheng Bin has a habit of playing cards?" Lin Fan sat down where Zheng Bin was sitting at that time and made a gesture.

"Habit?" Xin Chen began to recall the few times she had the experience of playing cards with Zheng Bin, "Habit, what kind of habit" She was sorting out her memories while muttering to herself, wow, like a lightning bolt in her brain, "Ah, I remember, he likes to hold playing cards." ”

"To be precise, he will pick up the poker when he is excited to play cards," Lin Fan found the poker they used at that time from under the coffee table in the living room, two sets of loose cards, the card box has long been gone, Lin Fan put the cards on the coffee table one by one, "The one on the left is the one I just started playing, and the one on the right is the one I bought later, have you noticed any difference?" ”

"What's the difference?" Xin Chen carefully observed the two decks of poker, "I remember, this one, Wu Xing seems to have made marks on the back of several cards, and it seems that a few of them have been taken by Zheng Bin, and there is saliva on them......"

"Well, what you said is a situation that we all know, but the most critical thing you didn't notice is that there are fewer cards in the second deck, a big king, a small king and a billboard, and the first deck of cards is all." Lin Fan unfolded the cards.

Looking at Xin Chen's thoughtful look, Lin Fan continued: "Why did Wu Xing do things on the back of the first deck of poker? He didn't want to make a lot of money at all, but to urge everyone to change to a new deck of cards, but he didn't want this new deck of cards to be the murderous poker he had been preparing for a long time. ”

"Wait, didn't you go downstairs and buy the second deck of poker?"

"That's his trick, he has already bought out the other brands of poker in the store downstairs in advance, and there is only one brand left, so I can only buy this kind of brand at that time, only in this way can he facilitate the later drop, at the same time, this practice is also more hidden, even if someone finds that the poker is coated with cyanide, chemicals, and substances, others will not suspect him first, because that deck of cards is what I bought.

He should have prepared the same brand of poison poker in advance, and changed hands when I entered the door and took the cards in my hand. ”

Xin Chen frowned, and then said: "But I still don't understand, if you poison poker, even if you don't hold it like Zheng Bin, won't everyone else have the opportunity to contact cyanide, chemicals, and substances on your skin?" ”

"No, that's where Wu Xing's plan is tight, and that's why the second deck is missing three cards. Do you know why Wu Xing insists on playing the Fraud Golden Flower and not playing anything else, because the Fraud Golden Flower does not need a king! Because of Wu Xing's previous complaints, coupled with the only selectivity, this provided guidance for Zheng Bin's habits.

Wu Xing was the first to hand the poker to Zheng Bin at that time, and at the same time he also emphasized that he continued to play the fraud Jinhua, so Zheng Bin must have taken out two kings and billboards in advance when he took the cards, and put them aside, but he didn't know that these two kings were the death sickles that sent him away, and as for the billboard, it must have played an isolation role to prevent other cards from being stained with cyanide, chemicals, and things.

Wu Xing deliberately lost to Zheng Bin for many games, and while Zheng Bin was excited, he subconsciously urged his habits, and he involuntarily picked up the three cards that did not need to be wasted.

Because the dose of cyanide, chemicals and substances smeared on the playing cards is not large, Zheng Bin will have 5-20 minutes of reaction time after contact, and when it was judged that Zheng Bin's mouth has been almost touched, Wu Xing immediately terminated the game and began the second part of the plan. ”

Listening to Lin Fan's inference, Xin Chen secretly reenacted the situation in his mind in chronological order. The more I think about it, the more I am afraid, such a plan is advancing step by step, every sentence contains Wu Xing's means, and every action hides Wu Xing's murderous intentions.

"No, I'm going to go to the team," Xin Chen's expression was painful, "I'm going to ask him in person in front of everyone in the team." ”

"No," Lin Fan grabbed Xin Chen, who was walking out quickly, "Not to mention that we haven't even found key evidence, let's just say that the attacker hiding in the dark hasn't even found his identity, your rash action like this will not only startle the snake, but also push yourself to the brink of danger." ”

"So what to do, do you just watch the case end with the kidnappers' revenge?" Xin Chen glanced in the direction of Zheng Bin's fall in the study.

"Sister Chen, you heard about me, I now have a general countermeasure, but I need your help."

"As long as I can restore the truth, I can do whatever you want." Xin Chen said in a firm tone, but suddenly thought that the boy who exuded a strong male aura at the moment seemed to be a pervert, and what he said would inevitably cause him to misunderstand, so he added, "But it is limited to investigating the case, if it is something else, don't think about it." ”

Lin Fan's brain was running rapidly at the moment to think about the next countermeasures, and was suddenly thundered by Xin Chen's last words, just like an overclocked CPU was suddenly poured with a bucket of cold water, the span of the girl's thinking jump was really large, and it seemed that she would never be able to keep up, "Sister Chen, your misunderstanding of me seems to be a little deep, I am that kind of person." ”

"Hmph, I admit that you are smart and a natural detective, but great detectives often have quirks, such as Sherlock Holmes has manic depression, he often smokes **, and he also practices shooting at home; Poirot is fastidious, unpretentious, and vain; Kaneda Ichikosuke used to be an alcoholic, and he was extremely unhygienic; And I suspect that you are definitely the same as Kaneda Ichikosuke and his grandson Aichi, a big pervert, and you, you still have fetishes......

"What, I have a fetish...... Lin Fan felt that he was petrified in an instant.
