We have all the space treasury in hand, so mere exile is nothing.

After hearing the prefect's question, Ye Qingran said bluntly: "Gather everyone together and check whether there are any traces of injury on the arms one by one. But I can't say what the specific traces are. If the murderer notices it in advance, it will inevitably be covered up."

The prefect nodded and waved to the county magistrate: "Go and do it, the sooner the better."

The county magistrate did not dare to refute, so he had no choice but to comply.

This county government office looks big, but in fact it doesn't have many people, at least not in Ye Qingran's opinion.

All the government officials were standing neatly on the field. After a brief screening, a total of three people with scars on their arms were found.

"Roll up your sleeves." Ye Qingran stood in front of them and memorized their faces.

None of the three people objected and rolled up their sleeves obediently.

Ye Qingran looked carefully at the scars on their arms and frowned slightly.

When she sprinkled poison on the murderer, she clearly remembered that it was sprinkled on the neck and arms. The man was wearing wide-sleeved clothes at the time. If he raised his hand to wipe his face, the powder would definitely be stained on the skin of his arms.

The effect of this medicine appears slowly, and the murderer will never notice it immediately. Then whenever his body temperature rises due to exercise or stress, the medicine will react immediately and directly burn his skin.

So there must be burn marks on the murderer's arms.

But it cannot be ruled out that the murderer discovered the presence of the medicinal powder and tried to cover up the wound. It is also possible that he directly scratched off the flesh at the wound.

The three people in front of them all had injuries of varying degrees on their arms, and they had been looking at the wounds healing for several days.

It's just that their conditions don't seem to be very good, their wounds are not cleaned well, and they don't heal well.

"What's your name, and how did you hurt your arm?" Ye Qingran asked, standing in front of the first person.

This is a boy who works as a sweeper in the county government office. He is relatively young, about sixteen or seventeen years old. There is a large burn mark on his left arm. Because he did not use good medicine, the wound has worsened. The uneven skin looks... Somewhat terrifying.

He kept his head lowered and spoke in a low voice: "My name is Xiaohu, and I am the boy responsible for sweeping the backyard and chopping wood to light the fire. My arm was burned by the heat when I was lighting the fire a few days ago. I didn't kill anyone..."

Ye Qingran said nothing and carefully confirmed his wound again. It was indeed a burn, but he couldn't confirm whether it was a heat burn or a medicine powder.

The wounds caused by the two methods were very similar, and there were signs of decay around his wounds that were difficult to identify.

"What about you?"

The man standing in the middle was a little timid. He was tall and thin, but he kept his neck trembling and couldn't even speak clearly.

"My, my name is Han Shu... I am, a yamen servant in the county government office. The scar on my arm was... from when I was fighting with the prisoner..."

After he finished speaking, he trembled even more violently, as if he was about to be punished.

Ye Qingran frowned slightly: "Why are you nervous?"

Hearing her question, he just lowered his head lower and did not answer her question.

"Let me ask you, since you are a government servant, you should be good at martial arts. Why are you the only one who was injured?"

"Yes...it's because I'm the closest and they don't dare."

Ye Qingran didn't ask any more questions and looked at the next person.

The next person seemed much calmer. Although he looked respectful, he did not show any fear. He stretched his arms straight and was not afraid of inspection.

She looked at the man's wound. It was a stab wound, but there were burn marks around it. She didn't know how it was caused.

"name?"

"Dong Liao, my arm was injured because the prefect was in danger two days ago. In order to protect you, I was stabbed by a gangster in a panic. I don't know what was on the knife, and the wound became like this."

He spoke calmly and looked a little troubled, as if he didn't know how to deal with the wound.

"Then didn't you go to the medical clinic for a checkup? The wound is quite serious." Ye Qingran asked.

He sighed: "Of course I went, but the doctor said that I was contaminated with some medicinal powder. After simply helping me stop the bleeding, he said that there was nothing serious around the wound. Just remember to change the dressing."

Ye Qingran grabbed his arm and looked at it carefully for a long time, then nodded and walked aside.

Seeing this, Chu Qingyun walked over quickly and asked, "How are you doing? Do you have any clues?"

"Not yet. Although my powder was sprinkled on the murderer, to be honest, I'm not sure how much he could have been infected through his sleeves. The wounds on these people are all very similar, the only difference is that the one named Han Shu Yes, there are no burn marks on his wounds."

"But I think this person is very suspicious."

Chu Qingyun pondered for a while and continued, "First of all, his wound was not a simple knife wound, but a piece of flesh was cut off directly. Even if he had traces of burns before, there is no problem now."

Ye Qingran nodded: "Indeed, and his state is very strange. As a government servant, he has been working in the county government for some time. He should not have seen big scenes. It was just an inspection, and he was frightened. That’s it.”

"It's better to start with him first and ask carefully."

"it is good."

Han Shu was taken to a room alone. Ye Qingran and Chu Qingyun sat opposite him and asked: "Han Shu, let me ask you, the prefect was assassinated a few days ago. When you fought with the assassin, Have you seen his appearance clearly?"

"No...no."

Ye Qingran put his hand on his chin, his eyes blazing: "According to what you said, your injury was accidentally scratched by the assassin when you were fighting with him. Did your Lordships give you very little monthly money? Why didn't you even get the injury? Take good care?"

"No, it's not. I just can't bear it...it doesn't matter, I'm in good health."

"Well...then tell me what happened on the day the prefect was assassinated."

"That day when we went out to investigate, right at the gate of the county government office, a masked assassin suddenly flew over. We couldn't react, so the assassin got close... It was Dong Liao who blocked the way for the magistrate in time. In front of you, only then did you let the master be safe and sound."

He calmed down a little, "We followed the order of the magistrate and went to fight with the assassin, but, our martial arts were not as good as him, so he ran away."

"Come here, bring Dong Liao in again."

After Ye Qingran spoke up, someone soon opened the door and brought Dong Liao in and sat next to Han Shu.

"Dong Liao, let me ask you, what exactly happened on the day when the prefect was assassinated, do you still remember?"

Dong Liao frowned slightly and fell into deep thought, and then answered: "It was very confusing at the time, and I can't remember some things clearly."
