When Lin Ran and Guo Ting arrived at the police station, they happened to meet Fan Beixiao, a kid squatting on the steps of the guard room with the doorman Lao Wang at the gate of the police station, smoking, the two were talking and laughing, Fan Beixiao saw Lin Ran and immediately walked over.

"Yo! Isn't this our big beauty school flower? How did you get together with Brother Ran? Fan Beixiao saw a playful smile on the faces of the two of them, and that look was more obscene than anything else.

"Don't talk nonsense!" Lin Ran glared at Fan Beixiao.

"You talk, I'll go first!" Guo Ting's face was a little embarrassed, she turned around and hurried away after saying this.

"Brother Ran, this girl seems to be interesting to you!" Fan Beixiao saw Guo Ting's figure that seemed to be a little flustered and left, and his face was meaningful.

"Shut up, it's all about you!" Of course, Lin Ran knew why Guo Ting was blushing.

"By the way, Abei, I'm looking for you for something!" Lin Ran suddenly remembered.

"What's the matter?" Fan Beixiao asked.

"Use your miniature recorder for me!" Lin Ran said.

"Miniature recorder? What do you want that for? Fan Beixiao looked at Lin Ran with a puzzled expression, not understanding what he wanted that thing for.

The miniature recorder is modified by Fan Beixiao according to the tachograph, which can be carried with him after being modified by Fan Beixiao, and the picture is clear, and the power can be kept in 24 hours.

"What do you care so much for?" Lin Ran had a straight face, he didn't want Fan Beixiao to know that he was going to search for evidence.

"Oh!" Fan Beixiao didn't speak when he heard Lin Ran say this, and he almost guessed what Lin Ran was going to do.

Lin Ran followed Fan Beixiao to the place where Fan Beixiao worked, Fan Beixiao took out a small bag under his workbench, took out a button-like thing in it and handed it to Lin Ran. Lin Ran looked at the small button in his hand, there was a small hole in it, that place was the place where the miniature recorder was placed, and it was pinned to the clothes when it was used, which was very convenient. And there's a little red button on the back of the clasp that you can press to record what you see.

Lin Ran didn't say anything, he knew how to use this thing, so he stopped talking nonsense, turned around and put the buttons in his pocket and walked towards Wang Changhai's office.

"Wait, Brother Ran! This thing should work for you! Fan Beixiao held something that looked like an electric baton in his hand and mysteriously stuffed it into Lin Ran's hand.

"What's it for?" Lin Ran looked at the electric baton-like thing in his hand, which was not light in his hand.

"It can see your handprints! The main thing is that it can see the blood stains hidden on the walls! Fan Beixiao whispered in Lin Ran's ear.

"Holy!" Lin Ran couldn't help but scold in his heart, this game should be so perverted! Even the hidden bloodstains can be seen, sure enough, Fan Beixiao's shot must be a high-quality product, Lin Ran looked at Fan Beixiao and couldn't help but glance at him. With this thing, it was too helpful for Lin Ran.

When Lin Ran went to Wang Changhai's office, Wang Changhai happened to be there, and it didn't take much effort to come out, and Wang Changhai directly agreed.

Lin Ran didn't dare to delay for a minute, and went out of the police station and took a taxi directly to the villa. When Lin Ran stood in that villa for the second time, he felt that the air was a lot more depressed. I don't know if it's because of psychological reasons, or because of something else, Lin Ran always feels weird, a little eerie.

Lin Ran took out the miniature recorder and pinned it to his collar, turned on the switch, and after doing all this, Lin Ran bypassed the cordon and walked inside. When passing by the big tree in the middle of the yard, Lin Ran took a few more looks, and there was nothing bare on the tree, not even the crows all the time.

Just a few steps later, Lin Ran suddenly stopped, looked around, and looked at Lin Ran for a long time and didn't find anything. Lin Ran's brows furrowed, his sudden strange feeling, the feeling of being stared at, made Lin Ran feel very uncomfortable.

After looking around, Lin Ran didn't find the source of that feeling, so he gave up looking and walked towards the house. As soon as I entered the house, a disgusting smell came from the room, and even though the corpses had been dragged away, there was still a smell of decomposing corpses permeating the room.

The place where the deceased's body lay had been drawn with white lines, and Lin Ran looked around several rooms and found nothing useful. Looking for clues like this, I will definitely not find any useful clues, just when Lin Ran was worried, Lin Ran inadvertently touched a heavy thing in his pocket, and Lin Ran suddenly thought of the thing that Fan Beixiao gave him.

Lin Ran hurriedly took out the electric baton-like thing, which was a bit like the mobile phone Big Brother that he used before, and the length was about the same as that of an ordinary smartphone. There's a screen-like thing in front of this electric baton and a push power supply on the side. Lin Ran pushed the switch up, and the screen lit up, emitting a blue-purple light about one meter in diameter, much like ultraviolet light.

Lin Ran tentatively shone the blue light towards the ground, and sure enough, he found some messy footprints, and seeing this scene made Lin Ran feel refreshed. Those footprints were not very clear, and according to Lin Ran's observation, these footprints should belong to the two children in the deceased's family.

However, Lin Ran did not give up, but closed the curtains, the light in the room was much darker, and the footprints were much clearer. Lin Ran squatted on the ground and searched carefully inch by inch, trying to find something useful.

Suddenly, Lin Ran found a speckled thing, like the shape of water droplets on the floor. Lin Ran hurriedly followed the direction of the spot, only to see that there were more and more traces of the spot, gradually gathering together. Lin Ran couldn't help but gasp as he looked at the spots on the ground, because those spots gathered together looked very much like traces of blood dripping. This was definitely a major clue, because Lin Ran clearly remembered that those bodies had no obvious injuries at all, let alone bleeding. This proves that the blood stains are not those of the dead!

And the bloodstains did not disappear here, but spread inward intermittently, Lin Ran followed the traces all the way, and sure enough, he found several other bloodstains. Looking at the intermittent bloodstains, Lin Ran could be sure that those bloodstains were definitely not from this family, because there were too many bloodstains.

Lin Ran looked at the blood stains on the ground, and out of the corner of his eye, he inadvertently caught a glimpse of the white line drawn by the police next to him on the ground where the corpse was lying on the ground, Lin Ran suddenly remembered that the place where he found several other blood stains was also next to the white line, is there any connection between this? Lin Ran thought to himself.

Thinking of this, Lin Ran hurriedly walked towards the room where the strange mask was found, I don't know why, Lin Ran faintly felt that he would definitely find something in that room, this was an intuition.
