Chapter 408 Looking at each other
"You are right. Even if the murderer successfully breaks through the secret room, he must 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 board.
Therefore, the murderer thought of a way to replace the screw. "
"What?"
Su Xinghuo said in surprise: "What's the point of this? 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.
Because of 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 of the bolt, and put the magnet down to attract the nut on the bed.
Subsequently, 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.
Hang the nut up slowly and put it on the spring.
Afterwards, the murderer took another thin iron rod with a 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 rod, and there was no difference at all. "
After Li Ang finished speaking, the audience fell silent.
The guard of the Prince's Mansion, Sikong Ji, 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.
嗡—
The seemingly solid screw was stretched forcibly under the pull of force, 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 unusual. 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 Fu'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 returned to the Sea Charm temporarily to pick up personal belongings, and happened to hear the rustling sound.
That should be the process of Chen Qiwei using mussels and replacing the screw.
As for why you didn’t do it until yesterday,
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.
The replacement of the screw at this time 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 Si Wang must use drawstrings to fix the quilt, that is to say, his lying position is predictable.
When the nut is almost screwed to the end, use a magnet tied with a rope to hold the nut down for a certain distance, and then pull out the spring to expose the hole of the bolt.
Now it's time for the murder weapon to appear. "
Su Xinghuo closed his eyes, took a deep breath, ".Rapier."
"Exactly."
Li Ang nodded and said: "The rapier in Chen Qiwei's room is heavy, flat, and sharp, and its diameter is just enough to pass through the bolt hole.
If my guess is correct, Chen Qiwei disassembled the blade and hilt of the rapier ahead of time, and used a thin wire to bypass 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 thread around the handle of the knife, tied it into a knot, then lifted it high, hung it above 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 blade of the sword fell down, just killing the heir king lying on the bed. "
Li Ang said: "The blade of the sword is not diminished, and it smashed 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 asked subconsciously.
"The blood leaves 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 board can ask him to perform the designated sword dance.
He was worried that during the process of killing the heir king, the rapier would be bumped, and later a passenger asked him to perform the rapier sword dance, 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 killing each 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 to this cabin, but the occupants of rooms 7 to 14.
Continuously interrogated and cross-examined, and regarded the last person who entered and exited Room No. 9 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 skate mechanism,
If it wasn’t a coincidence, the passenger couple 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 pinches the nut with one hand, slowly rotates it, and removes the nut from the spring screw.
Then he puts his finger on the bottom of the screw and props 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 has been lying on the ground, trying to hear the conversation downstairs, until now.
