First of all, it is not like other types of poisons that can be thrown directly into strong acid, and decompose by the strong corrosiveness of the latter, because cyanide, chemical and material will generate hydrogen cyanide extremely toxic gas when it meets acid, which can cause death in an instant. Secondly, due to the strong coordination of cyanogen, it cannot be preserved in metal utensils, so its storage is generally selected in glass bottles and placed in a darker place.

Based on the above two reasons, the first thing Lin Fan observed after entering the house was the several rooms on the shady side of Wu Xing's house, according to the structure of the house, it should be the kitchen, bathroom and study in turn, the doors of these rooms were closed, and nothing could be seen, so Lin Fan pretended to have diarrhea, if he could find an opportunity to investigate, it would be the best, if not, he would just test Wu Xing's reaction.

Without waiting for Wu Xing to reply, Lin Fan quickly pushed open the bathroom door while secretly observing Wu Xing's reaction, and he just glanced over here and then naturally talked to Xin Chen, not here? Lin Fan thought about it, after all, the bathroom space is small, and it is often excused by outsiders, so it is indeed not an ideal hiding place.

After exploring the bathroom and not finding what he wanted, Lin Fan estimated that the time was almost up before he put water to rinse, and then walked out slowly, but he did not immediately sit back in the living room, but walked to the kitchen next to him, "Brother Ang, your house is really well decorated, much more beautiful than our house." As he opened the kitchen door, a strange smell of fumes and green onions hit him.

"Lin Fan, don't move, I don't know any politeness." Xin Chen blamed on the side.

"It's okay, after all, I'm still a child, I just moved a little later, and I'm afraid that the smell of the decoration will be big, so I closed the door," said, Wu Xing opened the door of the study, "This one is for the study, but Xiao Chen, you know me, the old man is a rough one, he doesn't like to read, he just puts on a show, and the two rooms here are the master bedroom and the second bedroom," Wu Xing walked over, "You can look at it casually, in fact, my decoration style is mainly set according to Xiao Chen's taste, haha." ”

Listening to Wu Xing's hearty laughter, Lin Fan seemed to see a hint of banter in his eyes.

The clock in the living room was swinging to 12 o'clock, Xin Chen glanced at Lin Fan, turned to Wu Xing and said, "It's noon, why don't we go out for a meal, talk while eating." ”

"Okay, there's a store downstairs that does good food, I just found it." Saying that, Wu Xing picked up the key and led the two of them out.

Lin Fan's original plan was to come to Wu Xing's house to investigate first, and then let Xin Chen trick Wu Xingyu out under the pretext of having lunch, and he himself took the opportunity to sneak in and search for evidence, of course, the premise of all this must be based on two points, one is that the door of Wu Xing's house is a handle lock that does not reach the super B-level lock cylinder, and the other is that he will not lock the door after he goes out.

The first premise objectively exists, after all, more than ten years ago in Ningxi, most of the anti-theft doors in the community were handle locks, and most of the lock cylinders could not reach Class B; And the second premise must be artificially created.

"Oops, my phone was left on your couch." Xin Chen said to Wu Xing, who had already taken a few steps.

"How can you be a good criminal policeman?" Wu Xing counted Xin Chen's words, so he had to reflexively open the door.

When Wu Xing locked the door for the second time, Lin Fan spoke: "Eh, Brother Ang, I'm sorry, my backpack is still in your room, I originally wanted to come back to pick it up after eating, but it turned out that my stomach was really uncomfortable, so I didn't eat together at noon, the doubts I found were those I said in the morning, anyway, Sister Chen knows it, you can study it at noon." ”

Wu Xing threw the key to Lin Fan: "Sister Chen, Sister Chen is so affectionate, no wonder I even learned the fault together, haha." ”

Lin Fan opened the door, took his schoolbag under Wu Xing's gaze, and then closed the door vigorously, "Let's go." ”

The purpose of this is mainly to take advantage of people's inertia, if a thing is repeated several times, but find that it has little meaning, then the human subconscious will produce inertia, Wu Xing may be swayed by this kind of heart, so the last time he did not lock the door.

Originally, I wanted to learn Conan just now, and blocked the chewing gum on the lock of Wu Xing's door, who knew that Wu Xing had been staring at him, so he had to give up, and now it seems that he can only use the tools in his backpack, Lin Fan hid in the corner, secretly observing Wu Xing and Xin Chen, until they walked into a Hunan restaurant at the entrance of the community, he quickly turned around and ran towards Wu Xing's house.

Randomly pressed a house number, the voice-activated door opened quickly, Lin Fan climbed to the fifth floor in one breath, and estimated that there was no one in the neighbor's house opposite, Lin Fan buckled the cat's eye on the door of Wu Xing's house, and twisted it down vigorously one by one, and a hole with a diameter of nearly 6 centimeters immediately appeared on the door, and then Lin Fan took out the slender I-shaped lever in the backpack, stretched the thinner one into the hole, and let the side of its I-shape stuck above the handle in the door, and then Lin Fan nested the thicker other lever on the other side of the thinner one. With a hard pull down, the simple lever torque easily opened the door of Wu Xing's house, and Lin Fan pushed the door in.

Xin Chen in the Hunan restaurant felt extremely tormented at the moment, in order to give Lin Fan a longer time to infiltrate, she had to make a false deal with this murderer with a beast heart, feeling the playful gaze of the man opposite, Xin Chen suppressed the anger in his heart: "Wu Xing, what do you want to eat, you can order it, I will invite you today." ”

"It's really rare, Xiao Chen actually invited me to dinner, you have never looked at me before."

"Wu Xing, you are far away again, let's discuss the case." Xin Chen frowned.

"What is there to discuss in the case, the above is almost finalized: the kidnappers intended to obstruct the detection, deliberately retaliated, broke into the house and poisoned the house, what else do you want to discuss," Wu Xing's face suddenly became hideous: "Just that kid, after a few casual words, I really think I am a great detective, and I want to learn from Sherlock Holmes?" I don't want to think about who gave him that name, stupid! ”

Xin Chen looked at Wu Xing opposite, and suddenly there was a burst of inexplicable worry in his heart.

"Xiao Chen, I really want to be good to you, I advise you, there are some things you don't touch, you don't have the ability, you don't have the obligation, don't set yourself on fire!"

"What do you mean?" Xin Chen held back the uneasiness in his heart.

"How old is that kid Lin Fan this year?" Wu Xing suddenly changed the subject,

Xin Chen didn't react for a while, but his sudden heartbeat was violent and he couldn't breathe.

Wu Xing looked at Xin Chen with interest, and he grinned: "You said that burglary can sentence him for several years?" ”

"What!" Xin Chen stood up in shock, the blood in her whole body boiled, and then her whole body was cold and lost her blood, "You, what are you talking about, I don't understand!" ”

"Hehe, don't you understand, too, a guy under the age of 16 can't be sentenced to burglary, so I prefer the other," Wu Xing's face was covered with a terrifying smile: "Burglary died accidentally." ”
