Ask Sword

How did the murderer commit the crime?

Su Xinghuo asked hastily, Random suddenly came to his senses, there was a more important question, Who is the murderer?

hehe.

The answer had already surfaced in his mind, Li Ang beckoned to the ship's receptionist without haste, told him a few words, let him go get something,

Afterwards, Li Ang waved his hand and said, To answer this question, we must first clarify something.

This puddle of water on the ground next to the bed.

He came to the water stains and squatted down, saying: After the ice skate theory was proved to be unfeasible, the water stains became more suspicious.

Who caused the water damage? Why do water spots remain?

The murderer. To cover up the traces?

Singer Shi Yajing asked uncertainly.

That's right.

Li Ang clapped his hands, Before the king died, he lay obediently in the bed fixed by the belt, the kettle and the water cups were all on the table far away, obviously he didn't spill the water on the ground for drinking.

It can only be the murderer trying to cover up the traces.

So, what kind of trace?

If the murderer left fingerprints at the scene, he could just wipe them off with a cloth, making the iodine crystal fingerprints appear invalid.

If the murderer left hair at the scene, he should pick it up and take it away.

If the murderer was wounded and bleeding at the scene, he was worried that someone would use his blood for a blood type test to find out his identity. Then he should wrap up the wound and take a rag to wipe off his own blood on the ground.

However, what remained at the scene was a puddle of water. The blood stains left in the water did not come from the murderer's wounds, but from the victim, namely the heir Xia Yuanjia.

You mean, the murderer cleaned the murder weapon and left water stains?

Sikong Qiu, the guard of the Prince's Mansion, squinted his eyes and asked: But, why?

Since the murderer can come and go without a trace, and enter and exit the secret room at will, why can't he take the murder weapon out of the room and clean it up again? Or simply throw the murder weapon where no one can find it.

It's simple, he can't do it.

Li Ang smiled and said: Last night was the bonfire festival on the island, even though it was windy and rough, there were still many aborigines and foreign tourists on the island, sitting on chairs inside the house watching the Sea Charm by the light of the fire, chatting while drinking.

The talisman lights on the ship are bright, and when the murder weapon falls into the sea, there will be movement and it will be discovered.

What's more, the place where the Sea Charm docked was very close to the shore, so even if the murder weapon was thrown into the sea, it would be easy to find.

Therefore, cleaning the blood on the murder weapon directly in the room is almost the best solution.

If I'm not mistaken, the murderer originally hoped that the plasma gushing out from the wound on Si Wang's neck would soak the entire bed and drip down along the side of the bed, turning the water stains into a pool of blood, thereby eliminating this flaw.

It's a pity that he didn't expect that King Si's life enjoyment was more extravagant than he thought, and the water absorption performance of the sheets and quilts was so good that it sucked up all the blood.

Let the water content in the water stain be far more than a few blood streaks.

And this kind of behavior also represents one point-the murderer is not as powerful as we expected.

Li Ang glanced over the faces of Fei Lian, Su Xinghuo and others, and said calmly: He can't enter and leave the room at will, and he can't disappear out of thin air. He must wait until the time when everyone on the Sea Charm lands on the island before he can start his murder plan.

To be precise, he never actually entered the room.

Everyone asked in disbelief: Didn't you really enter the room?

I haven't entered the room, how could I kill Yuan Jia?

Su Xinghuo said in a deep voice: The alarm symbol in the room is intact, no spiritual power fluctuations have been detected, the doors and windows have not been damaged, and there is no hallucinogenic ingredients in the wine. It is impossible. Yuan Jia was persuaded by the murderer to commit suicide Bar?

Li Ang smiled slightly, stretched out his finger, and pointed to the top of his head, Look, everyone, the only part of the secret room that is not sealed is on the ceiling.

That is, the holes for the eight bolts that fasten the bed in room three upstairs to the planks.

Hole for the rivet?

The captain froze for a moment, then suddenly realized, No, I touched these eight bolts before.

Their screw caps are firmly in place and fit snugly against the ceiling.

In the upstairs room, it is impossible to tighten or unscrew the nut through the wooden floor.”

No, it's okay.

Before Li Ang finished speaking, the receptionist went back and forth, with a strange expression, holding two things in his hand, which were a set of bolts of the same type used in the rooms in the VIP area, and a pile of mussels placed in an iron basin.

These mussels are the delicacy used by the aborigines on the island to receive foreign tourists. They kept vibrating in the iron basin, knocking the metal basin to clang.

Trouble.

Li Ang expressed his gratitude to the receptionist verbally, reached out to take the bolt, and showed it to others, Look, everyone, the nut and the screw rod of this bolt are firmly fixed together and indestructible.

Without touching the nut, the bolt can be unscrewed by passing through the mussel.

While talking, Li Ang took out the most vigorous mussel from the iron basin, and put its shell on the top of the screw of the bolt.

Feeling out of water, the mussels trembled more violently,

The bolt is vibrated and vibrates at high frequency,

And the nut, unexpectedly loosened automatically, rotated, and moved towards the end of the screw.

Under the incredulous eyes of everyone, with a snap, the hexagonal nut fell out from the end of the screw and hit the ground.

The high-frequency vibration of the mussels is transmitted to the bolt, causing the nut and the screw to vibrate at the same time.

The friction force that originally fixed the two is reduced. Eventually, the nut, breaks away from the screw.

Li Ang said: After the nut falls out, the screw can be pulled out,

In this way, there is a hole between the upstairs room and the downstairs room that can pass through.

This is the first part of the Chamber of Secrets.

He silently added in his mind that if he had an electric toothbrush in his hand, he didn't even need the exotic mussels. Just press the electric toothbrush on the surface of the bolt, and the bolt would vibrate and separate.

Dai Xu's complexion suddenly changed, and he subconsciously said, Wait a minute, you mean, Chen Qiwei, who lives in Room 3 upstairs, is the murderer?

Like him, Chen Qiwei also worked on the ship. The two had known each other for several years, and the other party had no grievances with Xia Yuanjia, so how could they kill him?

Before Li Ang could answer, Fei Lian squinted his eyes and asked, Isn't it? Even if we do this, we can loosen the bolts and make holes in the two rooms.

But when we entered the room during the day, all eight bolts were well secured to the ceiling with no missing nuts.

Could it be that the murderer upstairs, after unscrewing the nut through the board,

Re-tighten the nut through the board?
