Ask Sword

You're right. Even if the murderer succeeds in breaking the secret room, he still has to find a way to restore the secret room before others notice it.

Li Ang said: Without using spiritual power, it is almost impossible to re-tighten the detached nut on the screw through a thick layer of wood.

Therefore, the murderer thought of a way to replace the screw.

What?

Su Xinghuo said in surprise: What's the point? The nut should be screwed tightly or not.

The murderer doesn't need to really tighten it, he just needs to make the bolt look like it is tightened.

Li Ang smiled and said, First, the murderer used mussels and vibration to make the nut fall off.

Due to the angle, the nut will inevitably fall on the soft, flat bed, and will not roll around and fall into the corner.

The murderer pulled out the screw rod, tied a vertical magnet to the string, passed through the hole in the bolt, and put the magnet down to attract the nut on the bed.

Then, the murderer put a tight spring that looked like a screw but was actually hollow inside into the hole.

The spring is hollow inside, and the murderer can use a bent needle or a tool such as tweezers to pass through the spring and hold the nut.

Slowly hang the nut up and over the spring.

Afterwards, the murderer took another thin iron rod with similar diameter and length, and inserted it into the hollow spring to make it fit tightly. From the outside, it looked the same as an ordinary screw, and there was no difference at all.

After Li Ang finished speaking, the audience fell silent.

Sikong Ji, the guard of the Prince's Mansion, took a deep breath, Where's the evidence?

Li Ang stepped on the bed, reached out and pinched the bolt outside the upper left corner of the bed, and pulled it hard.

Hum——

The seemingly solid screw, under the pull of force, elongated forcibly, revealing the essence of the spring, exposing the thin iron rod hidden inside.

No wonder.

The captain suddenly realized, I had clearly broken all the bolts on the ceiling before, because it couldn't be broken no matter what, so I didn't find anything abnormal. It turned out that there was an iron rod hidden inside.

That's right, I only wanted to understand all this after hearing Master Dai's words just now.

Li Ang nodded and said: Master Dai Fu said that yesterday afternoon, the couple who lived in Room 5 on the upper floor wanted to return to the Sea Charm to pick up their personal belongings, and happened to hear the rustling sound.

That should be the process of Chen Qiwei using mussels to replace the screw.

As for why you waited until yesterday to do it,

Exotic mussels are a specialty of the island and can only be obtained after the boat docks.

At the same time, most of the passengers on the ship went to the island to play, including the king who was afraid of the curse and often stayed in the cabin. He couldn't help being lonely. He went to the deck in the afternoon and looked at the lively island.

At this time, the replacement of the screw is the least likely to be noticed.

After replacing the bolts, Chen Qiwei waited for the night to fall.

There are strong winds and waves at night, so King Si will definitely use drawstrings to fix the quilt, that is to say, his lying position is predictable.

Chen Qiwei first pulled out the thin iron rod in the middle of the spring, and used tweezers to repeat the same trick, unscrewing the nut bit by bit-this process does not require mussels, and there will be no noise, which will wake up the king or the people in the nearby room. resident.

When the nut is almost screwed to the end, use a magnet tied with a rope to suck the nut down for a certain distance, and then pull out the spring to expose the hole of the bolt.

It was time for the murder weapon to show up.

Su Xinghuo closed his eyes, took a deep breath, . Rapier.

That's right.

Li Ang nodded and said: The rapier in Chen Qiwei's room is heavy, flat, sharp, and its diameter is just enough to pass through the bolt hole.

If I guessed correctly, Chen Qiwei disassembled the blade and hilt of the rapier in advance, and used a thin wire to go around the groove at the end of the blade to form a structure similar to a meteor hammer.

Then he passed the rapier through the bolt hole, dropped it, and began to shake. Dr. Su, can you lend me the scalpel and surgical thread?

Su Xinghuo took out the scalpel and sutures from the medicine box,

Li Ang took it, quickly wrapped the suture around the handle of the knife, tied it into a knot, then lifted it high, hung it over the pool of blood at the head of the bed, and shook it from side to side holding the thin thread.

The weight of the rapier itself, the length of the rope, and the range of shaking are all superimposed. When the shaking range of the blade of the rapier reaches its peak, the murderer suddenly releases a length of thin wire.

The falling blade of the sword just happened to kill the king who was lying on the bed.

Li Ang said: The blade of the sword remained undiminished, and it smashed into the cabinet clock next to the wall, so the clock will display the ugly time.

As for the water on the ground, the murderer poured clean water down along the bolt holes to clean the blade.

Why don't you draw the sword up and wash it?

Singer Shi Yajing subconsciously asked.

The blood has left traces. If the blood splashes on the ceiling during the process of drawing back the long sword, it will be exposed instantly. Therefore, this method can only be used.

Li Ang said: Chen Qiwei himself is a sword dancer, and the passengers on the ship can let him perform the designated sword dance.

He was worried that during the process of killing the heir king, the rapier was bumped, and a passenger asked him to perform the rapier sword dance afterwards, which would expose himself.

Simply do nothing, pretend to be injured some time in advance, and can no longer perform the sword dance during the next voyage.

The whole process is interlocking and murderous step by step.

After the captain and the crew found out that the king was murdered, the first thing they suspected was not him who had never been in the cabin on this floor, but the occupants of rooms 7 to 14.

Constantly interrogating and cross-examining, the last person who entered and exited Room No. 9 was regarded as the number one suspect,

Everyone fell into his logical trap unconsciously.

If it wasn't for the door of Room No. 9 being closed too tightly, vetoing the possibility of the ice skate mechanism,

If it was not a coincidence, the passengers and couples in Room 5 upstairs accidentally heard the sound of Chen Qiwei shaking the bolts with mussels,

This time he will successfully escape suspicion and sanctions.

Li Ang pinched the nut with one hand, slowly rotated it, and removed the nut from the spring screw.

Then he put his finger against the bottom of the screw and propped it up.

The whole process encountered no resistance, and with a snap, the screw fell to the floor of Room 3,

Li Ang's eyes, through the bolt holes, met those of Chen Qiwei who was lying on the floor of Room 3—he had been lying on the ground, trying to hear the conversation downstairs until now.
