"Huh?" After hearing the sheriff's answer, Mu Fei was stunned for a moment, "You don't think so?" But ...... "This guy just talked for a long time, didn't he mean that he thought the murderer was human?"

"I'm just saying that the possibility that the murderer was an ordinary human cannot be ruled out." The sheriff replied coldly, "Of course, I don't rule out the possibility that the murderer is a demon. ”

"What do you mean?" Mu Fei was a little confused.

"I don't guess the identity of the killer until it's confirmed." The sheriff said, "If I used to say that the murderer was a human, but now, now that I know that there are demons in this world, I can't rule out the possibility that they are demons." ”

Mu Fei admired this man's adaptability a little, ordinary people will subconsciously reject things like demons, even if they know the existence of the other party, thinking that that kind of thing is far away from their own lives, and it is impossible to have anything to do with themselves.

But the man in front of him naturally accepted the existence of demons and incorporated them into his own thinking.

"In our line of work, if we fix the identity or scope of the murderer in our minds in advance, it is easy to affect our future investigation, and even affect our judgment and observation." The sheriff frowned and looked at the river, not knowing what he was looking at.

"I see." Mu Fei nodded, this should be regarded as the other party's professional habits, doubt everything before determining the truth, and feel that everything is possible in the process of investigation, so that the thinking will follow the direction where the clues point, rather than following the direction that he has predetermined in his mind in advance. This also allows him to be more objective and impartial in the process of investigation.

This sheriff is indeed a rare excellent police officer.

"By the way," the sheriff suddenly turned to Mu Fei and asked, "Did you see something just now?" "So focused on one direction that I didn't even notice a person squatting next to me, I guess I saw something useful.

After being reminded by the other party, Mu Fei remembered that he had indeed seen something by the river just now.

I looked in the direction I had just looked, but I saw that the thing was gone.

"Why can't you find it? It's possible to be washed underneath. Mu Fei said to the sheriff, "I'll go look for it." ”

With that, he walked downstream. After walking a few steps, I noticed that the sheriff had followed.

"Let's take a look, maybe you kid really found the clue." The sheriff said.

"But...... Would you like to investigate this with me? "Wouldn't the police have any opinions? Isn't it generally necessary for police investigations to be kept secret?

"Anyway, we have the same goal, so it's faster to check together." The sheriff did not have the slightest sense of secrecy, and said as a matter of course, "If the prisoner is a demon, I will leave it to you, and if it is a human, then it is my duty." ”

After Mu Fei heard this, he didn't say anything more, since the other party could think so openly, what did he have to worry about? Anyway, no one in the guild said that they were not allowed to investigate with people outside.

As they spoke, the two of them walked downstream together.

"Mr. Sheriff." After walking for a while, Mu Fei spoke.

"Zhang Jin." The sheriff spoke lightly.

"Mr. Zhang." Mu Fei changed his words when he heard this.

"You can call me Zhang Jin directly." The sheriff frowned slightly, and didn't seem to like the honorific title "sir" used by others for him.

Although Mu Fei was accustomed to using honorific titles for people he didn't know very well or older people, since the other party asked for it, he didn't bother with the details of these titles, so he changed his words again and said, "Zhang Jin, what were you doing squatting there just now?" "Since we said that we want to investigate together, then the information can be shared.

"Footprints." Zhang Jin replied coldly, "I saw a few footprints there. ”

"Footprints?" Mu Fei was a little puzzled, although there were not many people by the river, there were pedestrians coming and going every day, and it was normal to have footprints. And now it has been several days since the day of the incident, and even if there were footprints left at that time, it is impossible to keep them until now.

"Those footprints were just left, and I guess it has nothing to do with what happened that day." Zhang Jin said simply.

Mu Fei didn't ask any more when he heard this, since it had nothing to do with the case, then there was no need for him to gossip.

After walking for about two or three hundred meters, Mu Fei found what he had just seen in the grass by the river. The two of them picked it up and saw that it was a piece of cloth with a pattern.

"What is this?" Mu Fei was a little disappointed, and what he found after looking for a long time was a useless rag, which really frustrated him.

"This ......" Zhang Jin took the rag in his hand and looked at it over and over, and only after a while did he frown and say, "I can't be sure, but I feel that this fabric is very waterproof, and it shouldn't be on ordinary clothes." ”

Mu Fei took the rag from Zhang Jin's hand when he heard this, pinched it with two fingers and rubbed it gently, sure enough, the rag felt very strange, and it was definitely not the fabric on ordinary clothes.

Looking at the patterns on the rags, a flash of inspiration flashed in his mind, and he looked at Zhang Jin and said, "Do you think this is the one on the swimsuit?" ”

"Swimsuit?" Zhang Jin frowned and thought for a while, "It's really possible, I'll take it back and let the people from the appraisal department confirm it." As he spoke, he shoved the rag into his pocket.

"Even a swimsuit doesn't mean anything." Mu Fei looked at the river and said.

"No, there's a lot to tell." Zhang Jin said lightly, "How many people do you think will come to this river to swim in this season?" Also, unless it's deliberately cut with a sharp blade, a normal swimsuit won't break so easily. ”

When the other party said this, Mu Fei was shocked, not to mention that it was only early summer, and the temperature was not too high. In fact, even in the hottest Futian, not many people have been able to swim in this river in recent years. For no other reason, the river has been polluted by some factories upstream, and the water has become so muddy that it has long been unsuitable for people to swim in.

The so-called swimsuit party held by Fang Gongzi was just a group of people wearing swimsuits messing around in the yacht, and no one would really swim in the water at all.

If the rag was really a swimsuit, it was probably the one worn by someone who disappeared that day.

Mu Fei looked at Zhang Jin's expression, saw the other party frowning and looking at the river, and secretly thought to himself that although this person said that he wanted to take it back for identification, he must have made up his mind in his heart.

"Let me ask you," Zhang Jin was silent for a moment and suddenly spoke, "Is it possible for a demon to live in water?" ”

"I haven't heard of it." Mu Fei shook his head when he heard this, "But I think it shouldn't work." Since demons are similar to humans, they should not be able to survive in the water for a long time, but he is not sure if there are any high-level demons who have the ability to live in water, so he does not say enough.

Zhang Jin nodded slightly when he heard this, frowning as if he was thinking about something.
