"It's... it's Cao Wenhao."
"Who is Cao Wenhao? Where is he now?" Jiang Yueyang asked two questions in a row.
The old woman replied: "Cao Wenhao is my grandson's classmate. He lives next door. I don't know if he is at home at this time. My lord, my grandson has a good relationship with him..."
Jiang Yueyang understood the meaning of her last words, and said to her cryptically: "Auntie, our government handles cases with great care and attention to evidence, and will never wrongly accuse any good person. But since ancient times, human hearts are unpredictable, and good and evil are just a thought away."
The old woman also understood the implication of Jiang Yueyang's words and nodded with a heavy face.
Jiang Yueyang then looked at Prince Yan, "Your Highness, please go to the next door and bring Cao Wenhao over."
King Yan nodded subconsciously, but paused halfway through. He looked at Jiang Yueyang with a little dissatisfaction, "Why do you always ask me to run errands?"
"Yes, is there?" Jiang Yueyang didn't pay attention to this.
"I was asked to go to the Dali Temple to get the case file before, and now I am asked to go next door to bring the suspect over. Isn't this running errands?"
Jiang Yueyang smiled lightly, "Your Highness, these are all work."
"But they can do all these jobs!" King Yan pointed to the two clerks waiting on the side.
"I am an investigator from the Supervisory Department!" he said angrily again.
Jiang Yueyang instinctively glanced at the two clerks and patiently explained, "I'm not afraid that the suspect will escape and they won't be able to stop him! Your Highness knows Kung Fu and can bring the person here smoothly."
"Really?" Prince Yan looked at her suspiciously.
Jiang Yueyang nodded repeatedly, "Really, go quickly, now is not the time to worry about this, you should focus on the case."
Seeing that her tone was a little unhappy, King Yan obediently responded, "I know."
After saying this, he walked out.
Jiang Yueyang raised his chin towards the two clerks, "You two should go too and keep an eye on His Highness."
“Yes!”
After they left, Jiang Yueyang continued to check the door of the room and found a little black fluff in the hole of the door bolt.
She carefully picked up the strand of fluff and asked in a puzzled voice, "What is this?"
Bai Ze and the other two heard her voice and slowly walked over.
The system answered thoughtfully: [It is the velvet left by the repeated friction of black silk thread. ]
Jiang Yueyang's eyes lit up, and she speculated: [So, the murderer probably tied the door bolt with a black silk thread, and then pulled the bolt from the outside to lock the door after he went out, making people mistakenly believe that the door was locked from the inside by the deceased. If my speculation is correct, the silk thread should be...]
As she spoke, she looked up and found a hole in the paper-covered grid. The silk thread should have come out from here.
"Si Zheng, is there any problem with the hole above?" Bai Ze asked deliberately.
Jiang Yueyang thought for a moment and replied, "I found velvet left by repeated friction of silk thread in the hole of the door bolt. I suspect the murderer used silk thread to tie the door bolt, and then passed the silk thread through this hole. Finally, the murderer used the silk thread to pull the door bolt from the outside and lock the door."
"Can you do it?" Wen Jinnian asked.
Bai Ze: "You will know if you try it."
Afterwards, they asked the old woman for silk thread and conducted experiments according to Jiang Yueyang's speculation.
Jiang Yueyang and the others stood in the room, while Bai Ze pulled the thread outside. After repeated attempts, they successfully locked the door.
"There was no silk thread left at the scene. How did the murderer take it away?" Bai Ze asked loudly.
Jiang Yueyang thought about it and said uncertainly: "Try pulling it hard and see."
Hearing this, Bai Ze immediately pulled the silk thread in his hand hard. The silk thread broke, but the part of the silk thread tied to the door bolt remained on the door bolt.
"How is it?" Bai Ze's voice came from outside.
Jiang Xun opened the door and let him in. As soon as he came in, he looked at the door bolt and saw the silk thread on it.
At this time, Jiang Yueyang walked up to the old woman and asked, "Auntie, who broke open the door on the day of the crime?"
"It was Cao Wenhao." The old woman explained in detail, "That morning, I came to wake my grandson up for breakfast, but I called him many times but got no response. I was worried that something had happened to him inside, so I wanted to find someone to help open the door..."
The more she spoke, the more she felt something was wrong. "It was him. He must have killed my grandson. At that time, I was just about to go look for someone, and Wenhao from next door climbed over the wall and asked me what happened. After that, he came over and kicked open the door for me."
"Did you notice what Cao Wenhao was doing at that time?" Jiang Yueyang asked quickly.
The old woman burst into tears and said, "No, I saw my grandson hanging from the beam and I fainted at that moment."
"That's right!" Bai Ze suddenly said, "The murderer must have taken the thread from the door bolt at that time."
"Then there is only one last question left." Jiang Yueyang looked at Bai Ze and the other two.
How did the murderer make the victim lose consciousness?
Wen Jinnian asked tentatively, "Does the murderer know medical skills and how to make people fall asleep?"
"Asleep?" the old woman asked in confusion.
Jiang Yueyang immediately asked when she saw this: "Auntie, have you thought of something?"
"My grandson has been afraid of blood since he was young. He would feel dizzy when he saw blood, and in serious cases he would even fall into a coma."
Wow!
Everyone suddenly felt a ray of light shining over them, dispelling all the fog.
The murder mechanism in the locked room has been solved, and the bloodstains on the victim's clothes have also matched. As long as more evidence is found, or the murderer confesses, the case can be closed.
At this moment, the King of Yan's men arrived before him, but his voice had arrived first.
"Jiang Yueyang, I brought the person back."
Hearing the sound, several people in the room looked outside and saw a young man in his twenties standing behind King Yan, holding his stomach.
