Du Wenxing touched his head with some embarrassment, "Sir, I'm just some immature thoughts."

"It's okay, let's talk about it." Wei Yiqing said warmly.

"The villain thought that if the murderer came in through the gate of the cell, the scope of this would be too great. The jailer present might be suspected."

Everyone nodded. There was more than one prisoner in this prison. If the murderer wanted to enter through the gate, these people must be bribed.

"The villain thinks that this approach is not only difficult to operate, but also easily exposed when there are too many people and mixed people. The murderer should not choose this way."

The jailers nodded quickly, they must agree, so that most people can eliminate the suspicion.

Du Wenxing continued: "Then, the villain thought of another possibility."

He looked around everyone.

"Maybe the murderer has not been in prison."

"You mean, the murderer used a hidden weapon to silence these bandits outside the window? In this case, at most one of the jailers was bought and the hidden weapon was taken away afterwards."

The person who spoke was a coroner. He seemed to think of Du Wenxing's ideas and quickly made up for his mistakes to make up for the mistakes of accidentally offending the gang of prisoners before.

"So, these bandits were also caused by the incense blowing from the outside?" Wei Yiqing said, twisting his beard.

"This is how the villain guesses. This is easier to operate than drugging food, and it saves the bribery process." Du Wenxing said.

Clear ideas and clear organization.

Wei Yiqing also admired Du Wenxing's eyes.

"So, since the hidden weapon has been taken away, and after these bandits were killed, no one in the prison can be judged that the hidden weapon taken away is somewhere in this prison!" The coroner continued quickly.

"Search!" Wei Yiqing ordered, and all the prison guards, including the prison head and coroner, took action.

Everyone felt that the truth had been found, but Du Wenxing frowned himself.

He suddenly thought of another thing in his mind, why did the murderer bribe the prison guard to hide his hidden weapon?

It seems that there is no need?!

Is this hidden weapon quite special and easy to be recognized by people?

Or to confuse the situation?

...

He suddenly felt that his thoughts might have fallen into a misunderstanding.

Soon, the search results confirmed his idea. There was no hidden weapon hidden in the prison, and the outside of the prison was searched, but nothing was found.

Everyone looked at Du Wenxing with strange eyes.

"Didi", the system's voice suddenly rang in my mind, "Released an emergency mission: Unlock the murderer's method of committing the crime; reward: 200 chivalrous values; punishment: none."

Du Wenxing was cheered up. This task is good!

Because he has found some clues.

My judgment just now was indeed wrong.

"No?" Zi Donglai asked afterwards.

"Sir, really, there is no one. We have searched carefully. There are no weapons hidden around and in the cell." The head of the prison replied, feeling quite depressed. Without finding the weapon, he could not get rid of the suspicion.

Zi Donglai: "That's strange. How did these people be killed? Is it really-" His eyes looked at the jailers who were shrinking their heads.

"No, I understand." Du Wenxing, who had been lowering his head and thinking (actually looking at the system), suddenly looked up and said.

"The murderer was the one who was killed outside the window. The prison guards were innocent and no one was the insider."

After hearing the boy's words, several jailers looked over with gratitude.

Today, these prisoners have been under great pressure of being suspicious. Every time, this young man excuses them. People's hearts are full of flesh, so how can they not be grateful!

"Oh, what do you mean?" Wei Yiqing's eyes moved and he asked in a warm voice.

"I judged that the murderer was still using something mysterious outside the window to make these bandits faint, and then used a hidden weapon to kill them-"

Speaking of this, everyone around him frowned because his statement was no different from before.

Zi Donglai was about to say something and then held back. In his impression, this young man should not do such useless things, obviously there is still some information.

Sure enough, Du Wenxing continued: "The reason why these people do not have hidden weapons on them is actually not taken away by someone. Our previous thinking has fallen into a misunderstanding. In fact, there is another situation that can achieve such an effect, such as--"

He paused subconsciously, which caused annoying gazes among the people who were obsessed with hearing. He couldn't help but shrink his neck and quickly continued: "For example, the material of the hidden weapon they used."

Material?

What material can disappear automatically?

Zi Dong came in the field, and the two coroners had already looked dazed, obviously thinking about something.

"——The murderer's hidden weapon is made of ice, ice ridges or ice cones made of ice." Du Wenxing said it with confidence.

No wonder-

That's right, a hidden weapon made of ice will naturally melt over time, and of course it will not leave any traces.

Others also suddenly realized.

"But why did the murderer do this?" Wei Yiqing, who was twisting his beard and pondering, suddenly asked, "Is this causing trouble for himself? It's Xia Tian after all. Moreover, if you use ordinary hidden weapons, even if you leave them, you may not be able to find any clues?"

Du Wenxing stopped talking, which was also something he couldn't figure out. "Maybe it's because... it's easier for this murderer to create ice ridges?" he guessed.

Zi Donglai suddenly spoke, "This kid is right. The murderer used ice-making hidden weapon for convenience."

Speaking of this, he looked at Wei Yiqing with bright eyes.

Lord Wei's eyes lit up and he said, "Let the East, what do you mean..."

"That's right, the murderer is the blood bat demon!" He said firmly, and he had obviously determined that the murderer is the blood bat demon.

"Sir, this blood bat demon practices extremely cold skills. For this person, using water to condense ice is a very simple thing, just do it with your hands."

"In the direction of the prison, there was indeed a water tank outside, which was for the prison guards to get water." The prisoner suddenly screamed, and there was a joy in his words that he had survived the disaster.

"That's right. These bandits must be related to the Blood Bat Demon. I suspect that the cloaked man is the Blood Bat Demon himself. He came here to silence him in the early morning. With this man's light skills, it was even more relaxed to steal it. Then he took water from the water tank and condensed into an ice cone. He used this as a hidden weapon to silence all these bandits and then left quietly. Now it's summer, and the prison is even more stuffy. When the body is discovered, the ice cone has long been melted."

Zi Donglai concluded.

"Didi, the mission is completed, the chivalrous value is increased by 200."
