Ye Fan thought for a while, floated straight towards the window on the other side, and took a closer look at the same position, and sure enough, there were two identical thin line scratches.

"Fanfan, come over here and take a look. Li Qiaojing stood on the podium, looked in Ye Fan's direction, and suddenly beckoned to her.

Ye Fan's whole mind was on the scratches on the window frame, Li Qiaojing didn't understand this, she was bored and wandering at will, Ye Fan entered the classroom, she also floated in, walked around the classroom, and when she went around to the podium, she subconsciously looked at Ye Fan, but this look made her find something.

"Huh?" Ye Fan was interrupted from his thoughts, and drifted to Li Qiaojing's location suspiciously, looking in the direction she was pointing.

At first, she didn't see anything unusual, but she also knew that Li Qiaojing had been with her for so long and would not play with her at such a time, so she took a closer look, just as the moonlight was falling outside the window, and when she was dazzling, a refracted moonlight crossed her eyes.

"This is ......" Ye Fan's eyes moved, staring at the window near the front door, under the light of the faint moonlight, she could see a very shallow rectangular trace on the glass, that trace, as if there was a rectangular thing attached to that glass, so it fell on the dusty glass surface.

The traces of the rectangle on that side were very shallow, just like she couldn't find it when she stood very close, and it was also the relationship between the position and angle where Li Qiaojing was standing, and the passing moonlight reflected the slightest difference.

"This trace ......" Ye Fan raised his hand and compared the size of the rectangle, about 40 centimeters long and about 20 centimeters wide, and suddenly thought of something, and his eyes lit up: "Guillotine, yes, guillotine." ”

This position is exactly close to the top window frame, and two more thin lines are added......

Ye Fan stood on the podium, closed his eyes slightly, and the classroom in front of him in his mind was still the same as before the crime, Meng Hang and Cai Qianqian had not yet come, but the killing machine had already been arranged.

Two imperceptible steel wires crossed from the left window to the right window, hanging in the classroom, and in the dim light, a glimmer of light crossed the eyes, and when the gaze turned, a sharp guillotine glistening with cold light hung against the glass window on the left window.

There was a hole in the top of the guillotine, and a steel wire passed through the hole, hanging the guillotine steadily, like a monster that was bound and waiting to eat people.

Then Meng Hang and Cai Qianqian came in, they were a little drunk, Cai Qianqian looked at the classroom that carried her dream of setting sail with some emotion, Meng Hang accompanied her to talk about the world, from artistic life to life philosophy, and finally the lonely man and widow, dry wood and fire, did not notice that there were two thin wires hanging in the sky above the place they loved, nor did they notice the guillotine with a cold light.

Just when their interest was at their highest, the thin wire that did not have the guillotine hanging was quietly pulled, and as the thin wire slid down, the thin wire hanging the guillotine also slid with the traction, and the guillotine slid silently from the glass window to Cai Qianqian's air.

At this moment, the thin wire tightened, broke suddenly, and the guillotine, attracted by the traction of the center of the earth, fell to Cai Qianqian's neck without the support of strength......

Click!

Clean and neat, the corpse is separated.

Blood spurted out wildly, and the head rolled to the ground, too suddenly, when the head hit the ground, Cai Qianqian had not yet realized that she was dead, and her face still maintained a look of fascination with desire at the last moment.

When Meng Hang was in a high-pitched voice, he was stupefied by the sudden scene, and when he reacted, he withdrew in horror and retreated, sat down on the ground, looked at the blood-flowing headless corpse, looked at the head facing him, he fled in fright and ran out of the door.

During the time he left, a person came in quietly, took Cai Qianqian's head, and the murderous guillotine, and then left quietly as if he had never come.

Meng Hang, who had a thought, ran back again, and put the body into a black garbage plastic bag in a panic, he seemed calm, but in fact he was mentally confused, he knew what he was going to do, but he forgot the most important head and guillotine.

After cleaning up the scene, Meng Hang left with the plastic bag containing the corpse, and the door of the classroom slowly closed.

Ye Fan Huoran opened his eyes, the light in his eyes flickered, and he stroked his palm and drank lightly: "That's right." ”

It seems that Meng Hang really didn't lie, the real murderer in this case is someone else.

"But there is one more thing to prove. Looking sideways at the glass window on the right, Ye Fan muttered to himself thoughtfully.

"What else do you want to confirm?" Li Qiaojing didn't know what Ye Fan was thinking, and asked suspiciously.

The corners of Ye Fan's mouth hooked slightly, and he said, "Aunt Li, thanks to your discovery, you have solved the problem that has puzzled me for a long time. ”

Even though the balance of her psychology is inclined to believe Meng Hang's confession, but the suspicion of this heavenly guillotine has always troubled her, even if she found the traces on the window frame, but Meng Hang They have not been in this classroom for a short time, especially Cai Qianqian has a long time lying on her back, and a bright knife hangs above their heads, they will not be able to find it when they are blind.

But the mark on the glass window, which resembled a guillotine, was a good solution to her doubts, and it was hard to notice the glass at night, not in the middle of their eyes, and if they didn't look at it specifically.

"Huh. "Being able to help Ye Fan, Li Qiaojing is also very happy.

Ye Fan floated out again through the window he came in, hanging in the air, looking at the nearest street tree under his feet, about three stories high, classroom 312 was on the third floor, about the same height, there was still some distance between the canopy and the window.

Ye Fan's body floated over, stopped between the canopy branches of the street tree, and took advantage of the faint moonlight to get over, pulled out the branches, and carefully searched between the branches and the trunk.

Tonight's moonlight is not too bright, the leaves are covered, and the light is even dimest, fortunately, Ye Fan's eyesight is good, with the steady improvement of cultivation, it has almost reached the point of being able to see things at night, and this dim light does not hinder her.

Suddenly, her eyes fixed on the junction of a branch and the trunk, where there was a rather deep fracture, she gently pulled the branch, and the junction was already exposed, and it only took a little more force to break the branch.

Ye Fan leaned his face over and looked at the fracture carefully, the incision was very neat, and the surrounding bark showed signs of turning out, this was not a normal fracture, nor was it a fracture cut by a sharp weapon, if it was wound around it with a thin wire like a steel wire, pulling it back and forth could cause such a fracture.
