"How so? If that's the case, who would have killed Azhu? Conan asked, confused.

"It's actually these things that killed Azhu." Li Canghai took out a blank piece of paper and unfolded it.

Everyone looked at the paper and found that there were some bamboo and hemp ropes painted on the paper, and everyone showed puzzled expressions.

Li Canghai said: "These things were found in the bamboo forest opposite Azhu's room, a curved bamboo, and half a human-high bamboo, and a bamboo that was cut from it, and these hemp ropes. ”

"These are just ordinary bamboo hemp ropes, nothing special, right?" Conan knew what he had found in the bamboo forest, but in his opinion, those things were the most common things, and he could not have imagined that they would be related to the murder in any way.

"Yes, it is precisely because these are the most ordinary things that they will not attract everyone's attention, because no one will think that it is actually these things that killed Azhu." Li Canghai said deeply.

Everyone looked left and right around the piece of paper, but they didn't have any clue and shook their heads.

"Actually, I was able to figure out the murder methods of these murders, a large part of it was because of Brother Nan, if he hadn't taken me out for a walk, I wouldn't have figured it out." Li Canghai said.

"Me?" Conan was stunned, feeling a little inexplicable.

"Yes, at first I was confused, no matter how I thought about it, I couldn't figure out what the connection between these things was, but when I was investigating, I happened to find a cut bamboo in the bamboo forest, and the direction was exactly the door of Azhu's house, and I just thought it was a little strange at that time. It wasn't until today, when I saw a vaudeville show in town, that I figured out the key. Li Canghai said.

Conan touched his chin and looked at the piece of paper intently, but he still couldn't see why, so he frowned and asked, "What's the key to this?" ”

Li Canghai said: "Brother Nan should still remember that when the girl performed the empty-handed feather arrow, the arrogant man took out some parts and formed a crossbow on the spot, right?" ”

Conan nodded and muttered, "I naturally remember this." Don't...... Is that so? ”

Conan's eyes instantly became solemn, and his expression looked quite surprised.

Li Canghai knew that Conan had figured out the key, so he nodded and said, "Yes, just as Brother Nan thought, the murderer used these to make a simple and powerful crossbow. ”

"What are you talking about? Why can't I understand? Zhang Wenyuan touched his nose and asked suspiciously.

Li Canghai didn't remember to answer everyone, but clapped his hands, and several family members walked in with some bamboo strips and bamboo strips.

"These are models of the things I found in the bamboo forest, and maybe you will understand a little bit more when you look at them."

As he spoke, Li Canghai bent the bamboo strips, tied them with hemp rope, and put the cut bamboo face up, and quickly assembled a simple small bow and crossbow.

Everyone looked, only to see that the bow and crossbow were all made of bamboo hemp rope, the cut bamboo is the launch trough, the bent bamboo tied with hemp rope is used for charging, there is a small gap under the launch trough, the gap falls with the rope, and the rope used for the charge is connected together, and is wrapped around the bamboo erected behind.

The shape of the whole bow and crossbow is simple, but the use of only a few hemp ropes, but the effect of force is exerted to the extreme, which can be said to be ingenious.

Li Canghai had studied physics in his previous life and had some understanding of 'force', but Rao was like this, and he had to experiment more than ten times in the room before he succeeded in combining these unrelated things into a crossbow.

Looking at the bow and crossbow on the table, everyone was amazed, and they couldn't help but wonder a little, can a crossbow composed of such a simple thing really be used?

Li Canghai saw the doubts in everyone's hearts, he ordered someone to find a chopstick, then put it in the groove, looked at everyone, and said, "Now, you can see the power of this crossbow." ”

As he spoke, Li Canghai gently hooked his fingers, and several hemp ropes moved at the same time, directly releasing them from the bamboo in the back, only to see the bamboo chopsticks in the groove rush out in an instant, and swoop into the fruit in the opposite fruit bowl. At the same time, the crossbow also collapsed.

Everyone was taken aback at the same time, and they were stunned on the spot, looking at the scattered bow and crossbow in amazement, and they couldn't speak for a long time.

"Brother Li, what's going on?" Conan asked, surprised.

Li Canghai said lightly: "Pull the simple longbow made of bamboo into a full moon, and then put the launch trough on it, and then block the hemp rope of the full moon with bamboo, set up the mechanism, and wait for the mechanism to start, and the bamboo knots placed in the bamboo trough will **** away." And the entire bow and crossbow is built on balance, so that after exerting force, it will instantly fall apart and scatter in the bamboo forest. In this way, no one would have thought that the murder weapon that killed Azhu was actually a simple bow and crossbow. ”

After hearing this, everyone looked at each other, such a subtle killing method is simply incredible!

"Wait a minute, I'm a little puzzled, even if the murderer set up this bow and crossbow as you said, how did he set up the mechanism? How do you know when Azhu will open the door? Also, what about the painting next to Azhu? Conan asked.

"In the bamboo forest, in addition to these things, I also found a puddle of water in the agency's information area, if we guessed wrong, it must be ice water. The killer tied ice cubes to the rope that triggered the mechanism message, then calculated the time, and when the ice melted to a certain amount, the mechanism was triggered. And that painting flew out at the same time as the bamboo that killed Ah Zhu, so when she killed Ah Zhu, that painting would appear next to her. Li Canghai paused, frowned, and said: "As for how the murderer calculated that Azhu would open the door at that time, I think it should be that the murderer informed her in advance and asked her to open the door at a specific time!" ”

"Although this plan is feasible, there are many uncertain factors, if the ice melts early, or the ice melts slowly, or Azhu does not open the door, wouldn't this series of arrangements made by the murderer fall short?" Conan asked pensively.

Li Canghai nodded, frowned, and said: "Judging from these, the murderer should be very familiar with Ah Zhu's living habits, and he knew that Ah Zhu would ask the maid to boil the medicine at that time, so he came up with these." What's more, these are inconspicuous in the first place, even if there are all kinds of accidents as you said, but who would have thought that a piece of bamboo could be used as a murder weapon?
