Playing bad and eating melons: The whole court is laughing? No, no

"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 wonder if he's home at this time. My lord, my grandson has a very good relationship with him..."

Jiang Yueyang understood the meaning of her last words and said to her cryptically, "Auntie, our government always adheres to evidence when handling cases and will never wrongly accuse any good person. But since ancient times, human hearts are unpredictable, and good and evil can be determined by a single thought."

The old woman also understood Jiang Yueyang's implication and nodded with a heavy face.

Jiang Yueyang then looked at Prince Yan, "Your Highness, please go next door and bring Cao Wenhao over."

Prince Yan nodded subconsciously, but paused halfway through. He looked at Jiang Yueyang with a hint of 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 files before, and now I'm asked to go next door to bring the suspect over. If that's not running errands, what is it?"

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 just worried 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 responded obediently, "I understand."

After saying this, he walked out.

Jiang Yueyang raised his chin towards the two clerks and said, "You two should go too and keep an eye on His Highness."

"Here!"

After they left, Jiang Yueyang continued to check the door of the room and found a bit of black fluff in the hole of the door latch.

She carefully picked up the strand of fluff and asked softly, wondering, "What is this?"

Bai Ze and the other two heard her voice and slowly walked over.

The system thoughtfully answered: [It is the velvet left by repeated friction of black silk thread.]

Jiang Yueyang's eyes lit up, and she speculated, "So, the murderer likely used black silk thread to tie the door latch, then pulled the latch from the outside after leaving, locking the door from behind. This would make it appear that the deceased locked the door from the inside. 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 in the hole of the door bolt from repeated rubbing of silk thread. I suspect the murderer used silk thread to tie the door bolt, then passed the thread through this hole, and finally used the thread to pull the bolt from the outside and lock the door."

"Can you do it?" Wen Jinnian asked.

Bai Ze: "You'll 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 inside the room while Bai Ze pulled the thread outside. After repeated attempts, he successfully locked the door.

"There was no silk thread left at the scene. How did the murderer take the silk thread away?" Bai Ze asked loudly.

Jiang Yueyang thought for a moment and said uncertainly, "Try pulling it hard and see."

Hearing this, Bai Ze immediately pulled hard at the silk thread in his hand. The thread broke, but the part tied to the door bolt remained on the 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 latch 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 incident?"

"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 without getting a 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. I was just about to go look for someone when Wenhao from next door climbed over the wall and asked me what happened. Then 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."

"That's right!" Bai Ze suddenly said, "The murderer must have taken the silk thread from the door latch 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 have medical skills and know how to make people sleep?"

"Asleep?" the old woman asked in confusion.

Seeing this, Jiang Yueyang immediately asked, "Auntie, have you thought of something?"

"My grandson has been afraid of blood since he was young. He gets dizzy when he sees blood, and sometimes even falls asleep in serious cases."

Hey!

Everyone suddenly felt a ray of light shining over, dispelling all the fog.

The murder mystery had been solved, and the bloodstains on the victim's clothes matched. As long as more evidence was found, or the murderer confessed, the case would be closed.

At this moment, the King of Yan's men arrived before his arrival, 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.

Jiang Yueyang walked out and asked, "Doesn't he live next door? What took you so long to come back?"

"This kid said he had a stomachache and stayed in the toilet, which delayed him for a while."

"Are you feeling down in your stomach? What a coincidence?" Jiang Yueyang squinted and looked at Cao Wenhao.

Cao Wenhao smiled ingratiatingly, "I dare not lie to you, sir. My stomach really feels uncomfortable."

"Really?" Jiang Yueyang walked up to Cao Wenhao and stopped, looking at him with a half-smile. "I happen to know some medical skills. Can I take a look at you?"

Cao Wenhao's pupils trembled, but he quickly declined with a smile, "I dare not trouble you, sir. I am much better now."

Jiang Yueyang just wanted to scare him, not to check his pulse. He nodded and said, "In that case, come with us back to the Supervisory Office."

Cao Wenhao was shocked. "Why...why should I follow you back to the Supervisory Office? I have done nothing wrong."

"This officer has determined that the deceased, Li Jinxian, was murdered. Mr. Cao, as the last person the deceased saw before his death, is a major suspect."

"I didn't kill anyone!" Cao Wenhao immediately defended himself.

Jiang Yueyang smiled slightly, "I didn't say you killed anyone. I just suspect you did."

"Does your Excellency have any evidence?"

"With evidence, it's no longer a suspicion." Jiang Yueyang raised the corner of her mouth slightly. "Mr. Cao is a scholar and should be familiar with the laws of Daxia. As a suspect in this case, he should cooperate with the government investigation."

Cao Wenhao moved his lips, but had nothing to refute.

The next second, he caught sight of the old woman in the room and hurriedly said, "Auntie Li, Brother Li and I are close friends, and I would never harm him. Besides, you know me best. Please help me explain to the adults how I could possibly kill Brother Li."

Hearing what Cao Wenhao said, the old woman suddenly became angry and rushed forward. Bai Ze quickly stopped her.

The old woman stared at him with red eyes and screamed, "Besides me, you're the only one who knows that my grandson is afraid of blood! You killed him, you killed him!"

"Auntie Li, what are you talking about? What does Brother Li's death have to do with his fear of seeing blood?" Cao Wenhao became more and more uneasy.

Jiang Yueyang smiled and said, "You'll have to ask Master Cao about that."

"The little one doesn't know."

"It's okay, you'll know." Jiang Yueyang raised her chin towards him, "Please."
