Du Wenxing touched his head a little embarrassed, "My lord, I'm just some immature ideas. ”

"It's okay, let's hear it. Wei Yiqing said gently.

"The villain thought that if the murderer came in through the door of the cell, the scope would be too big, and all the jailers present would probably be suspicious. ”

Everyone nodded, there was more than one jailer in this prison, and if the murderer wanted to enter through the gate, these people would have to be bribed.

The villain feels that this method is not only difficult to operate, but also easy to be exposed under the crowd, and the murderer should not choose this way. ”

The jailers nodded their heads busily, they had to agree, so that most of them could rule out suspicions.

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

He looked around at the crowd.

"Hopefully, the murderer did not go to prison. ”

"Are you saying that the murderer used a hidden weapon to kill these bandits outside the window? In this case, at most one of the jailers will be bribed, and the hidden weapon will be taken away afterwards. ”

He seemed to have thought of Du Wenxing's train of thought, and hurriedly made up for his mistakes to make up for the mistakes he accidentally offended these jailers before.

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

"The villain guessed that this is easier to operate than drugging food, eliminating the need to buy. Du Wenxing said.

Clear and well-organized.

Wei Yiqing looked at Du Wenxing's gaze and also admired it a little.

"Then, since the hidden weapon has been taken away, and from the fact that no one in the prison has left since these bandits were killed, it can be judged that the hidden weapon that has been taken away is somewhere in this prison!" the servant hurriedly continued.

"Search!" Wei Yiqing ordered, and all the jailers, including the cell boss and the servants, took action.

Everyone felt that they had found the truth, but Du Wenxing frowned on his own.

He suddenly thought of another thing in his heart, why did this murderer bribe the jailer to hide the secret weapon?

It doesn't seem necessary?!

Is this secret weapon more special, and it is easy for people to recognize their identity?

Or is it to confuse the line of sight?

......

He suddenly felt as if his thoughts might have gone into a misunderstanding.

Soon, the results of the search confirmed his thoughts, the secret weapon was not hidden in the prison, and the surrounding area of the prison was also searched, but still nothing was found.

Everyone looked at Du Wenxing with strange eyes.

"Dididi", the voice of the system suddenly sounded in his head, "Release a sudden mission: unravel the modus operandi of the murderer in the prison; reward: two hundred chivalrous points; punishment: none." ”

Du Wenxing's heart perked, this task is good!

Because he's already got some clues.

My judgment just now was indeed wrong.

"Really?" Zi Donglai asked.

"Lord Hui, there really isn't, we have searched carefully, and there is no murder weapon hidden around the cell or in the cell. The cell boss replied, frustrated, that he would not be able to escape suspicion if he had not found the murder weapon.

Zi Donglai: "That's strange, how the hell were these people killed, is it really-" His gaze looked at the jailers who had shrunk their heads.

"No, I see. Du Wenxing, who had been bowing his head and contemplating (actually looking at the system), suddenly raised his head and said.

"The murderer is the one who killed outside the window, and the eldest brother of the jailer is also innocent, and no one responds. ”

Hearing the young man's words, several jailers looked at him with great gratitude.

Today, these jailers have been under great pressure to be suspected, and every time it is this young man who exonerates them, people's hearts are flesh and blood, how can they not be grateful!

"Oh, how do you say that?" Wei Yiqing's eyes moved, and he asked gently.

"Little judgment that this murderer still stunned these bandits outside this window with incense and other things, and then killed them with a hidden weapon-"

Speaking of this, everyone around frowned, because what he said was no different from before.

Zi Donglai just wanted to say something but held back, in his impression, this young man should not do such a useless thing, obviously there is a following.

Sure enough, I heard Du Wenxing continue: "The reason why these people didn't have hidden weapons on them was actually not taken away, and our previous thinking entered a misunderstanding. Actually, there is another situation that can achieve such an effect, such as——"

He subconsciously paused, causing the annoyed eyes of a group of people who could listen to him, and he couldn't help but shrink his neck, and hurriedly continued: "For example, the material of the secret weapon they use. ”

Material?

What materials disappear automatically?

In the field, Zi Donglai and Qi Zuo had already shown a sudden look, obviously thinking of something.

"—The murderer's secret weapon was ice, an ice ridge or ice pick made of ice. Du Wenxing said it with great confidence.

No wonder –

That's right, the hidden weapon made of ice will naturally melt after a long time, and of course it will not leave a trace.

Others also came to their senses.

"But why did the murderer do this?" Wei Yiqing, who was twisting his beard and groaning, suddenly asked, "Is this asking for trouble for yourself? It's summer after all." Moreover, if you use an ordinary secret weapon, even if you leave a hidden weapon, you may not be able to find any clues from it?"

Du Wenxing stopped talking, which was also something he couldn't figure out, "Maybe it's because of ...... It's easier for this killer to make an ice pick, right?" he guessed.

Zi Donglai suddenly spoke, "This kid should be right, the murderer used an ice hidden weapon just for convenience." ”

Saying this, he looked at Wei Yiqing with blazing eyes.

This Lord Wei's eyes lit up and said, "Donglai, what do you mean ......?"

"That's right, the murderer is the Blood Bat Demon!" he said categorically, obviously identifying the murderer as the Blood Bat Demon.

"My lord, this Blood Bat Demon is cultivating the Extremely Yin and Cold Exercises, for this person, it is a very simple matter to condense ice with water, just do it. ”

"In the direction of the prison, there is indeed a water tank placed outside for the jailers to fetch water. The cell boss suddenly screamed, and there was a joy in his words for the rest of his life.

"That's right, these bandits must be related to the Blood Bat Demon, and I suspect that the cloaked man is the Blood Bat Demon himself. He came here in the early morning to extinguish the mouth, and with this person's light skills, it was extremely easy to steal into this room, and then took water from the water tank casually, condensed it into an ice pick, and used it as a secret weapon to kill all these bandits, and then quietly left. It's summer, and it's even hotter in the prison, and by the time the body is found, the ice picks have long since melted. ”

Zi Donglai concluded.

"Dididi, the task is complete, and the chivalrous value is increased by two hundred. ”

A voice that made him happy came from Du Wenxing's head.
