Shen Shaokun and Han song were the only people in the room that day. Shen Tianfeng and his wife saw the quarrel with their own eyes. Then Shen Shaokun pushed Han song, causing death.

If the murderer killed someone in the room, how could they not see it?

Can you make people run away?

"No!" Li Yifan shook his head slowly and said with a smile: "you are all trapped in a misunderstanding. Who told you that the murderer killed people in this room?"

"Ah?" The crowd was stunned.

Han Shaocheng and others are directly confused. They didn't kill people in the room. How did the murderer kill people?

"You fall into the habitual thinking that the murderer must do it himself at the moment of the victim's death. In fact, it is not that the murderer escaped from this room, not to escape after killing, but to take away the weapon! " Li Yifan explained with a smile.

"Take the weapon?"

Shen Shaokun's eyes widened. "Do you mean that the murderer secretly took away the murder weapon while there was no one else in the room, and then escaped from the window after someone had already died? At last he left the weapon in the grass? "

"That's right!" Li Yifan nodded with a smile, "you have a good brain. That's it! The murderer is not so bold. He kills in front of people, so he can't be caught? He went into the room, just to take away the murder weapon, so as not to be detected the cause of Han Song's death and found on his head! "

People suddenly realized, "so it is!"

But soon Shen Tianfeng put forward another doubt, "that's not right. This room has been closed since the murder. Outsiders can't get in at all. How did the killer get into this room? "

"Yes! The windows are locked from the inside. They can't be opened from the outside. If you want to come in, you can only come in from the gate! " Shen Shaokun couldn't help echoing.

"It's about the identity of the killer. I'll explain it to you later." The corner of Li Yifan's mouth stirred up a meaningful smile, and his eyes swept over the faces of all the people. The look of all the people was overwhelming.

People look strange. When is it that he is still playing tricks?

At this time, Shen Kang asked curiously, "regardless of the identity of the murderer, how do you know for sure that the murderer must have taken the weapon before he ran away from the window, instead of just after he killed, he ran away from the window?"

As soon as this doubtful point was raised, everyone could not help nodding.

"Yes! How is the timing determined? "

They want to know how Li Yifan determined when the murderer left the room.

Li Yifan laughs and shows his hand helplessly. "This is not very sure. Do you think that if the murderer was in the room when he was killing, Shen Shaokun and Han song would not find him? What's more, if it's really the same as you guessed, the murderer should hide in the room when he kills. This room is so big, where can he hide? "

An explanation made people suddenly, but at the same time, they were not amused.

They are really confused to ask such a silly question.

Yes, when the murderer was in the room, they were not blind. Besides, when the murderer hid in the room, he would leave footprints and other marks.

Both the police and Zang long have checked the room, and there is no suspicious trace at all.

In other words, Shen Shaokun pushed Han song to death, and the murderer was not at the scene at all.

"Then it can be proved that the murderer actually killed in other places? But it's not right. If the murderer is not at the scene, how can he kill? " People can't figure it out.

Li Yifan picked up the filament and poured it into the air. The filament immediately changed from soft to straight.

"As you have seen just now, when this filament is hard, just like a silver needle, it penetrates deep into the vertebral point on the back, which will lead to sudden death."

"Yes, that's what you said."

"But even if this thing can replace silver needle to achieve the same acupuncture effect, if no one is applying the needle, there is no way to kill people?"

"Yes! Isn't Shaokun the one who killed people with a needle? "

All the people began to talk, and they were all puzzled.

Li Yifan listened to their comments and said with a smile, "what you said is true. It's impossible that Shaokun stabbed him with a needle, or he would have been seen long ago. But suppose, in fact, this glass wire has been pierced into Han Song's back from the very beginning, and just when he quarreled with Shaokun, Shaokun pushed him. When Han Song fell down, the fiber wire, which was not deep enough, suddenly went deep, leading to a sudden death? "

When this remark came out, everyone was shocked.

The crowd glared, and they all gasped for air in the next moment.

"Yes! If Han song falls down suddenly, when his back touches the ground, he just pushes the silver needle into the meat. If it's deep, won't he die? "

"So it is! No wonder, no wonder! "

They all suddenly realized, as if they understood everything.Soon, Han Shaocheng thought of something deeper. He turned his head and stared at Li Yifan, "that is to say, Han song had been watched by people earlier, and was secretly injected. Is there a premeditated plan to blame Shen Shaokun for his death?"

Pop!

"Smart!" Li Yifan snapped his fingers and said, "in fact, he is a burden that has been used by others. He tried to kill him and gave him an injection. Then he didn't know that he had a conflict with Shaokun and was killed. I don't think he knows how he died until he dies. "

"Damn it Han Shaocheng's face suddenly became very gloomy, "who is going to murder him like this?"

"Ha ha, who knows," Li Yifan's eyes narrowed slightly.

Han Shaocheng fixed his eyes on him, "since you can find out the cause of Han Song's death, you must know who the killer is! Han song is my most outstanding apprentice. I must avenge him! "

"Well, Han Tianyi, don't be angry. Don't be impatient!" Li Yifan's face was covered with a smile, and he picked up the filament. "Han Tianyi is not curious, why such a thin thing as hair can kill people?"

Han Shaocheng suddenly stagnated, and other people were confused.

To tell the truth, they still don't know whether the filament is the murder weapon mentioned by Li Yifan.

They also saw for the first time that someone could kill with such a small and fragile thing.

"It seems that Han Tianyi doesn't know," Li Yifan said with a stronger smile. "Let me explain to you. In fact, this is not an ordinary fiber. I have just carefully observed it for a long time. If I am right, it should be the fiber in some electronic products, such as the fiber in the earphone cable. "
