Boom!

Lu Fan landed steadily on the next floor of stairs, landing on the steps corresponding to the footprints.

On this layer of steps, Lu Fan stepped on the steps corresponding to the footprints, kept going down, and then jumped to the next step.

If you really walked out of this infinite staircase, then the three-story staircase would definitely have a connection to the classroom corridor, but Lu Fan didn't see it.

Three flights of stairs, without the slightest change, are all exactly the same.

"These footprints, no. ”

Lu Fan shook his head and did not continue.

"The phone has been checked, but there is no signal. Fu Jinglun, who was standing above his head, saw Lu Fan stop moving, so he said, "I also tried to shout, but no one responded, I put my ear against the wall, and I couldn't hear any sound." I guess we're stuck here, unable to communicate with the outside world. ”

Lu Fan also took out his mobile phone and looked at it, it was indeed no signal, as for shouting to try, Lu Fan gave up trying.

The footprints on the wall were not completed, and Lu Fan's eyes turned to the staircase handrail, which was made of steel, and between the handrail and the staircase, there was also a steel pipe as a support.

Lu Fan looked over little by little, and there was no rust on the handrails and steel pipes, which didn't seem to be a tofu slag project.

Like footprints, it is not possible to find some special steps through the rust or notches of the handrails, so Lu Fan began to visually inspect the data again, the length of the handrails, the length of the steel pipes, and the distance between each two steel pipes, and then made some calculations based on these data to determine the way to walk the steps.

After all of this failed, Lu Fan combined the data with the footprints on the wall to generate new data.

However, it still doesn't work!

"Isn't that a bit difficult?"

Lu Fan stood there.

On this staircase, except for the footprints on the walls and the handrails, at a glance, there is no more information to extract.

"Is the clue hidden?"

Fu Jinglun took out a pen from his arms and began to knock on the armrest.

Lu Fan walked to the other side and began to touch and knock on the wall with his hands.

The two of them knocked all the way from the top stairs to the bottom, and the result was very consistent, that is, nothing!

"I still don't believe I can't find it. ”

Unable to find anything on the wall or handrail, Fu Jinglun walked to the first step, squatted down, and studied the steps under his feet inch by inch.

"Is it at the back of the stairs?"

Lu Fan raised his head and looked at the top of his head.

Because all the stairs are exactly the same, it is very convenient for him to look at the back of the stairs, and he can look up.

On the back, there really is something!

In the very center, there is a cut mark about a foot and a half long, as if someone had cut it with a knife.

"Is this a trick?"

Lu Fan stared at the trace.

Of course, this trace man can do it, stand on the steps, take a knife, look up, and you can scratch it up the stairs on the next floor.

But if it's a human being, who would be so painful?

This is a school, who will bring this kind of weapon in?

"What does this mark mean?"

On the entire back, there is only that one trace, and nothing else.

Lu Fan stood there, thinking about it for fifteen minutes.

"What the hell?"

But I haven't remembered it yet.

There was a sound of footsteps overhead, and Fu Jinglun walked down, he had already checked every step under his feet.

"How?"

Lu Fan asked.

Fu Jinglun shook his head, "What about you?"

Lu Fan also shook his head.

"The three female students, they left a little before us. From the inside of the stairs for the time being, Fu Jinglun's eyes turned to the outside again, "Why can they successfully walk out?"

"You mean, the way out is on them?"

Lu Fan felt that this was really unlikely, when the girls left, neither of them followed, and the girls walked by themselves.

How did a couple of girls leave, they have absolutely no idea!

Since it's a hint, then it must be a hint for them to see, so what they don't see at all, how can it be a hint?

Of course, from those girls, Lu Fan was not completely unable to extract a little something, and when the girls went down, they were still talking.

"Oops, it's all class, hurry up. ”

"What are you afraid of, the history teacher is very talkative. ”

"Cut, that's because you have good grades, that's why you say that, we're not you. ”

Standing at the iron gate on the rooftop, Lu Fan heard a few girls say these words.

Could it be that the hint is in these few sentences?

Lu Fan muttered these words softly, trying to taste something from them.

Although Fu Jinglun can't be like Lu Fan, even if he doesn't listen deliberately, he can repeat it word for word, but he is more or less impressed, as soon as Lu Fan repeats it, he immediately knows what Lu Fan is talking about.

When Lu Fan was thinking, he was also thinking on the side.

"Damn, it shouldn't be because those are girls, so they passed?

After thinking about it, he couldn't think of it, Fu Jinglun guessed.

Of course he didn't think so, if this was the clearance requirement, then the two boys were destined to die here.

When he said this, he was just complaining.

However, an unexpected situation appeared, as soon as Fu Jinglun's voice fell, in this staircase, there was a sudden laughter!

Hee-hee~

It's a girl's laughter, and it's quite crisp!

Fu Jinglun's psychology is also strong, and in the claustrophobic environment, laughter suddenly came, and this level of horror could not startle him.

He turned his head and looked in the direction where the laughter had come from, and saw a girl in a school uniform sitting on the top step of the staircase.

This school uniform is completely different from the current school uniform style of Dawn No. 2 Middle School, and it is the kind of outdated old style at a glance.

There was no blood dripping from her body, no terrible wounds, and she looked no different from the average schoolgirl.

However, Fu Jinglun can be sure that this is definitely a ghost, not a human!

"Little sister, are you the one who trapped us here?"

Lu Fan looked at the female ghost who suddenly appeared very calmly.

"Hee-hee, yes. ”

The female ghost grinned and admitted it directly.

"What do you want?"

"I've been here for a long, long time, and I'm so bored, I'm just going to play with you. The female ghost rested her arms on her legs, her chin rested on her palms, and she laughed with two small dimples, "It's really fun to watch you look around on the stairs as if there is some treasure hidden here." ”

Fu Jinglun suddenly had a very strange feeling, the ghost in front of him was not terrible at all, but a little ······ Cute!

I actually think that the ghost is cute, the old man's juvenile heart has undergone some kind of strange mutation under the high pressure of the live broadcast?
