Zhao Dezhao took a deep breath and laughed: "Brother Li, I know you have such a good face, but handling the case is either nonsense. I don't know, but I don't know. There is no need to show off my strength for Zhaozhou's most clever reputation."

Zhao Dezhao didn't believe that Li Yi could discover the secret of the secret room in such a short time. The room was sealed, the doors and windows were locked, and there was no possibility of secret passages.

It can't be said that there are no clues, it's simply clueless.

Even if the gods come, they can't figure out why in such a short time.

Anyway, Zhao Dezhao had no clue at all, and he didn't think Li Yi would be better than him.

Li Yi ignored Zhao Dezhao. He stepped down from the chair and picked up the door bolt that was violently destroyed by Yun Zhaozhao: "Let's see you guys."

Yun Zhaozhao and Chu Ping came over, and Li Yi continued: "There are signs of being burned by fire on this door."

Zhao Dezhao said suspiciously: "What can such a weak trace mean?"

Yun Zhaozhao and Chu Ping were also confused.

Li Yi pointed to the door again: "There is a trace of a thin line tightening on the door."

Yun Zhaozhao stepped on the bench and saw a trace of the once-existing dust in the door.

Li Yi turned around and reached out to grab Yun Zhaozhao's head.

"What are you doing?" Yun Zhaozhao took a step back.

"I borrowed a piece of hair for you." Li Yi made a move to pull it out.

"What are you doing for borrowing my hair?" Yun Zhaozhao's eyes were full of alert.

"Don't let it go." Li Yi rolled his eyes and then pulled Chu Ping's hair.

Chu Ping also went to hide and stared: "I will accept my body, hair and skin, and I won't borrow it!"

Li Yi pursed his lips: "It's very important to solve the case."

"Since that's the case, then pull it away." Chu Ping stood there, letting him pull off a piece of hair about one and a half feet long.

Chu Ping still wanted to see Li Yi slap this rich child in the face.

"Hiss." Chu Ping exclaimed. The hair was connected to the scalp. It was thick and hard, very tough, and a little oily. It hurts when it was pulled off.

"Can the case be solved with just one hair?" Yun Zhaozhao was very surprised.

Zhao Dezhao looked even more dissatisfied.

Li Yi ignored her. He went to the next room to get a new door bolt and a bowl of oil lamp, wrapped the hair around one end of the door bolt, then closed the door, and hung the door bolt in the groove behind the door.

Li Yi used an oil lamp to ignite one end of his hair, and at the same time, Li Yi let go of his hand.

With a "click", the door bolt stuck into the groove.

The flames burned their hair slowly, and the flames gradually faded away. The hair had not yet burned out but had broken, falling slowly under the door bolt.

"What are you doing?" Yun Zhaozhao tilted his head, only to think Li Yiqi was strange.

Chu Ping also tilted his head: "What are you doing for burning it?"

Only a trace of clarity flashed in Zhao Dezhao's eyes. He clasped his hands and exclaimed: "So that's it! So that's it!"

Yun Zhaozhao frowned: "So what's going on?"

Zhao Dezhao said excitedly: "The method of committing the crime is actually very simple, not as complicated as imagined. The murderer just used a thin line object to wrap the door bolt, then walked around the door, closed the door and burned the object outside the door.

In this way, when the fire burns all the thin lines, the door will automatically be stuck by the door bolt. There is nothing else except the traces of the fire on the door bolt and the dust on the door. This house is like a secret room."

Yun Zhaozhao was stunned, then woke up: "So that's it! It's so simple!"

Yun Zhaozhao felt like she was pulled by a knife and her eyes were opened.

Chu Ping said in confusion: "But, my hair is not burned clean. Isn't the murderer afraid that the hair will not be burned clean. What will be left behind but will make a mistake?"

Li Yi said, "So, the thin thread used by the murderer must be extremely flammable. I took your hair before, just a small demonstration."

I thought my hair was the key to solving the case... Chu Ping secretly said, "Since it's just a demonstration, why don't you use your own hair?"

Li Yi rolled his eyes: "Doesn't it hurt to pull his hair? Are you stupid?"

Chu Ping: "..."

Then you can grab me!!!

Chu Ping matched several traces one by one and found that there were no omissions. Only then did he believe that Li Yi had really solved the mystery of the secret room.

Chu Ping laughed and said, "I'll just say that the top ghost is fake. It's still a case committed by people. The saying that ghosts and gods commit crimes is simply absurd."

Li Yi expressed contempt for this swinging materialist.

Not knowing what he thought of, Yun Zhaozhao and Chu Ping suddenly looked straight at Zhao Dezhao.

Zhao Dezhao touched his face, then was stunned. After hesitating for a moment, he stepped forward and bowed to Li Yi.

"What is this for?" Li Yi was startled and hurried to help him.

Zhao Dezhao did not move and said with a serious expression: "I just didn't recognize Mount Tai just now, and I looked down on Brother Li. I hope Brother Li won't be surprised!"

Li Yi said: "It's okay, it's okay, what Brother Zhao said before is not unreasonable."

Zhao Dezhao shook his head and insisted on bowing: "I have always said what I said. Since Brother Li has solved the mystery of the secret room, he should be my teacher. Please accept Dezhao's bowing!"

Inadvertently, he revealed his real name.

Li Yi was amused and crying. Zhao Dezhao was quite serious, but he was a gentleman who could make friends with him.

Li Yi quickly helped him up: "No need to do this, people have their own strengths and weaknesses. I just happened to be good at this. When I encounter something I don't understand in the future, I still need to ask Brother Zhao."

"Brother Li is modest." Zhao Dezhao's face also looked good, and he couldn't help but look up at Li Yi in his heart, no longer despised him before.

Yun Zhaozhao said: "Since the mystery of the secret room has been solved, how should we lock in the murderer?"

Li Yi opened the door and grabbed the trembling guy in: "What do I ask, what do you answer? If you are talking nonsense, don't blame me for sending you to the county government for a board."

The guy said timidly: "Just ask me, I will tell you everything."

Li Yi coughed: "Do you know, who has entered and left the Zhuangyuan Building today?"

The guy said: "Because of a murder case, there are few tourists from the Zhuangyuan Building today, and there are not many people who have gone upstairs. There is no one except a few of the men in the yamen and Mr. Zhang who came to see the paintings in Dongcheng."

"Who is this Zhang Yuanwai?" Chu Ping asked.

The guy quickly explained. After hearing this, Li Yi shook his head. This Zhang Yuanwai was the middle-aged Confucian scholar who was watching the painting.

When this person left, Manager Wan was still alive and had no time to commit the crime.

Li Yi said in a deep voice: "Think about it carefully, isn't anyone else going upstairs except for us yamen servants?"

"It's really gone. The villain has been guarding the stairs. If someone else goes upstairs, the villain will definitely see it."

Li Yi rubbed his chin: "So, except for us who have gone up the third floor, the only suspects are the yamen on the fourth floor of the crime scene."

Yun Zhaozhao suddenly said, "There is another one. I also saw a prison guard named Tao Peng going up the fourth floor. He is the man of the Wang Zhuanzhu."

"Oh? The man of the King's Bookkeeper?"

Yun Zhaozhao nodded and said, "He said he was going to get the King's Shoes, but I stopped him."

Li Yi was thinking. After a while, he remembered the thing that Manager Wan had "added his strength" and looked at the clerk: "Have you ever said something or did something strange before going upstairs to bed?"

"Strange thing..." the guy thought for a while and said, "It's there! He laughed as he went upstairs and said something shady to himself.

It sounds like… ‘It’s time for me to develop, it’s time for me to develop’ or something.”

Should I develop?
