Tang Dynasty detective

Chapter 490 The Chamber of Secrets
"Thank you, Immortal Elder." Lan Yue made a blessing to Li Canghai.

Li Canghai ignored them and let Yu Chengen push him into the murder room.

"Let's start. Be sure to search carefully." Li Canghai said after looking at the whole room.

Yu Chengen nodded, then walked into the room and searched carefully.

Li Canghai came to the table, picked up the brass lock and looked at it.

This copper lock was found by Conan before. The shape of this copper lock is like a small stone mortar. There is a lock core thinner than bamboo chopsticks in the groove, but the lock core has been broken from the middle.

Li Canghai weighed the copper lock, and looked back at the door, where the wood that fell from the door leaf was scattered on the ground.

The door leaf was slammed open, half of the door fell to the ground, and the other half of the door was tilted.

After thinking about it, Li Canghai came to the door on his own, and carefully observed the two doors.

Due to the impact of these two doors, one broke and fell to the ground, and the other was connected to the door frame, and both were damaged to varying degrees.

There was nothing unusual about the door that fell to the ground, and the strong impact knocked off the knocker of the back door of that door.

On the contrary, it was the falling door that caught Li Canghai's attention.

Although the half door was damaged, it was not particularly serious. There was an iron chain hanging on the inside door knocker, and a ring was hanging on the lower end of the iron chain, which seemed to be the door knocker of the other half door.

Li Canghai looked at the door, and a thought suddenly flashed in his mind, but before he could catch it, it disappeared in a flash.

He rubbed the center of his eyebrows, then fell into deep thought.

From what we saw in front of us, we can make an inference. After killing Hongmei, the murderer hung her to the beam of the house, and then deliberately made the room messy. After doing everything, the murderer tied the door knocker with an iron chain. Then locked the door with a brass lock.

But here comes the question, the murderer locked the door, how to leave the room?
All the windows in this room can only be locked from the inside. He has checked the windows and found that all the windows are locked from the inside like doors, and there is no damage. It is impossible for the murderer to escape through the windows.

"The doors and windows are closed, and they are all locked from the inside. Could it be that there is a secret passage in this room?" Li Canghai thought to himself.

He searched carefully along the walls of the room for a while, but he didn't find any mechanism secret passage, so he quickly rejected this idea.

At this time, Yu Chengzhuo ran over happily, holding a half-finger-long brass key in his hand, and said: "Brother Li, I found it! It should be this key!"

Li Canghai hurriedly took the key, he inserted the key into the copper lock, it really fit.

"Where did you find this key?" Li Canghai asked.

Yu Chengzhuo pointed to a row of wooden frames near the wall, and said, "It's just under that row of wooden frames."

"Why is it there?" Li Canghai looked at the wooden frame and frowned.

The row of wooden shelves is located on the west wall. After the murderer locked the door, why did he throw the key so far away?

What's more, did the murderer leave the key there on purpose, or did he just throw it away at will?

More and more mysteries appeared in Li Canghai's mind, which made the whole case more complicated and confusing.

"Brother Li, what did you think of?" Seeing Li Canghai lowering his eyebrows in thought, Yu Chengen asked.

Li Canghai shook his head. He rubbed his brows and said, "I have no clue. Indeed, as you said, the murderer is like a ghost. After killing someone, he disappears without even leaving a trace."

After finishing speaking, he let out a long sigh, and then fell into deep thought again.

It can be said that this is the strangest case he has ever encountered.

It's not that he has never encountered a murder in a secret room. The first murder he encountered in Datang was a murder in a secret room.

After the murder, the murderer used the ink fountain rope to pull up the door latch, creating the illusion of a murder in a secret room.

However, this method of killing requires a specific factor, that is, there needs to be a gap for the Modo rope to pass through, so that the murderer can pull the rope outside the door and bolt the door.

The present case, although similar to the Xiaoyang Village murder case, is also very different.

First of all, the room is closed, and the windows have no gaps.

Secondly, the door of the room was tightly closed, and it was locked from the inside with a copper lock.

Even with Xiaoyang Village's similar method, it's impossible to do it.

Because this kind of copper lock wants to be locked, a key must be inserted, unless someone holds the copper lock with one hand and inserts the key with one hand, the copper lock can be locked.

But in this way, the person who locked the door will be locked in the house, and if he does not open the copper lock, he will not be able to get out anyway without destroying the doors and windows.

However, in the murder case before him, the murderer not only locked the copper lock in the room, but also left the room without leaving a trace, which is a bit inconceivable.

Li Canghai sat at the scene of the murder all afternoon, until night fell, he didn't think of a reason, so he had to go back to rest.

After dinner, Conan came to Li Canghai's room.

Li Canghai poured him a cup of tea and said, "Brother Conan, in your opinion, who is the murderer of this murder case?"

Conan propped his chin with his hand, and pondered: "Based on what we have so far, we can't confirm the identity of the murderer. I asked people in the Zhang family. Although Hongmei is Zhang Wenyuan's concubine, she is kind and has no disputes with others. Never heard of feuding with others. No one seemed to have a reason to kill her."

Li Canghai nodded, and after thinking for a while, he said, "Brother Conan, do you think Lan Yue and the others are murderers?"

"I have suspected this too, but as far as I know, Hongmei, Lanyue and the others have a very good relationship. They are not like other big families who intrigue and cheat for favor. It is precisely because of this that they have always won Zhang Wenyuan's attention. Huanxin, apart from them, Zhang Wenyuan never took concubines again. Until a month ago, Zhang Wenyuan met Yu Yanrou and redeemed her, planning to take her as a concubine after building Baihualou," Conan said.

"From this point of view, it is true that Lan Yue said that they love sisters. Has Yu Yanrou's identity been found out?" Li Canghai asked.

Conan shook his head and said: "At the moment, I only know that Yu Yanrou is the flower head of Fendai Pavilion. She and Yu Chengzhuo are brothers and sisters. The two were originally rich children, but because they were deceived by bullies, their family fortunes fell. Yu Yanrou lives on the street , and later entered Fendai Pavilion as a prostitute, because of her orchid quality and heart, and was proficient in piano, chess, calligraphy and painting, she soon became the oiran of Fendai Pavilion. Bewitched by Rou, he offered money to redeem her body, and wanted to take her as a concubine."

"The Yu family is down, doesn't it mean that Yu Chengzhuo doesn't know?" Li Canghai asked in surprise, rubbing his nose.

"Yu Chengzhuo was studying far away in Chang'an, so he didn't know what happened at home. It wasn't until he returned home a month ago that he learned that his parents had died and his younger sister was living in a brothel. Yu Chengzhuo went to Fendai Pavilion and learned that Yu Yanrou had already died. He was redeemed by Zhang Wenyuan and brought back to the Zhang family, so he came to the Zhang family to find someone. Since the two are biological siblings, Zhang Wenyuan did not make things difficult for him, but treated him with courtesy and let him stay in the Zhang family."
