Lu Fan and Xiaomeng continued to search the corridors, checking classroom by classroom, everything they found so far was exactly the same as the description of the person during the day, the voice seemed to appear out of thin air in the room, there was no one, could it be that there was really a ghost?

Lu Fan shook his head, impossible, there will be no ghosts in this world, right... How should the matter in front of him be explained? What reasonable explanation can be placed here? Lu Fan's thoughts began to float again, but nothing appeared in his mind. Pen ~ fun ~ pavilion www.biquge.info

"Ping-pong, ping-pong, ping-pong" has been maintained with this voice for a long time, with a gentle rhythm, Xiaomeng's mood has gradually stabilized, and Lu Fan is carefully looking for the source of the sound.

Anyway, the other party can see it, and if the posture is stupid, it is better to be stupid, the two of them deceived themselves like this, holding one side of the wall with their hands and squatting forward like a train, "Lu Fan, what do you think this voice looks like?" Xiao Meng pulled Lu Fan's clothes behind him, and slightly relaxed the previously suppressed voice.

Lu Fan just got up at this time and looked into the classroom, like a battlefield scout, "How do I know..."

The classroom was still the same as before, empty, he sat down, and continued to answer, "However, it is quite similar to the beating of the heart, you listen"

Xiao Meng sat down like Lu Fan and listened carefully.

The rhythm of this sound is similar to that of the heart, and it always rings twice at a time, one big and one small, just like the contraction of the heart, the only difference with the sound of the heart is that it is the iron sound of ping-pong, not the fleshy thump.

"Could it be, what kind of machine ghost is it?, that kind of big robot with an iron heart, after death, it will become a ghost" Xiao Meng made this assumption with a worried face, which made Lu Fan cry and laugh.

"Xiaomeng, let's not talk about the existence of ghosts, the kind of iron-hearted robot you said is completely unscientific, okay? Robots can still accept using circuits as energy, why do you want to make a heart? It will bang bang, can modern technology make mechanical lifeforms?" Lu Fan sneered, and showed off his knowledge, he must have forgotten the books that Xiao Meng once asked him to read, she herself wrote them all, what she saw and heard was more than a hundred times more than Lu Fan, an otaku, but he was just a little afraid of ghosts, and it was because of his huge knowledge that Xiao Meng would have such worries.

"No, who said that, there are really that kind of big robots, and I've seen several of them" Sure enough, Xiao Meng said such a thing very seriously.

At this time, Lu Fan's eyes were about to pop out, and his face was incredulous, "Is there really one?"

"Hmm" Xiaomeng nodded, "It's in my house, there are several, and they're very obedient, but it's a pity that they can't speak and their heads aren't very good."

The head is not good? What does this mean, these robots have autonomous consciousness? Lu Fan was shocked, what kind of terrible black technology is this? They are all about to make Gundam, and sure enough, the really powerful technology is not accessible to ordinary people? Or is this something that only Xiao Meng's family has? Lu Fan's eyes gradually focused on Xiao Meng's face.

"Xiaomeng," Lu Fan opened his mouth to inquire, "Is this kind of robot you said common?"

"If I've seen it, there are four in total now, and there were two more before, and I dismantled and played with them."

Lu Fan only remembered at this time that Xiaomeng's identity didn't seem ordinary... Why did I forget it, and I actually thought of her as a stupid little girl.

"If you dismantle the robot, no one will teach you a lesson..."

"It's true that someone said a few words, but it's not a big deal."

At this moment, Lu Fan's perception of Xiaomeng's identity is much clearer again, I'm afraid it's similar to the princess, only six robots were dismantled casually, and there was nothing wrong, Xiaomeng's status can be imagined.

At this moment, the sound that had been ringing suddenly stopped, Lu Fan and Xiao Meng glanced at each other, and slowly stood up, in the process of talking just now, the last trace of fear between the two disappeared.

"Why did the voice stop" Lu Fan looked around, but didn't find any changes, it was still pitch black, the difference was that his eyes gradually adapted and became brighter and brighter.

Xiao Meng also shook her head for some reason, and the two continued to stay in the corridor and circle, just when they were at a loss, there was a change again.

A loud bang sounded on this floor, startling both Lu Fan and others.

The sound came and went quickly, but it disappeared all of a sudden, followed by the previous ping-pong sound.

The long rhythm sounded, and the nerves that Lu Fan and Xiaomeng had just tensed were relaxed.

"What is it?" Lu Fan didn't react for a while, the sound just now was very similar to the sound of water vapor evaporating when it met heat, but this kind of resonance beyond common sense was really weird, it was almost like the entire building was resonating, and then Lu Fan noticed that the sound of ding dong seemed to be beating on the soul, so that he unconsciously merged with the long and peaceful rhythm, and it may be for this reason that Xiao Meng was no longer afraid.

Although this voice filled the entire space before, it still gave people a relatively weak feeling, and it wasn't until the loud bang just now that Lu Fan was furious, and he didn't notice this matter, and if it was really the whole building resonating, then it should be more than the second floor.

"Xiaomeng, let's go to the other layers to have a look, okay?" Lu Fan wanted to verify this idea, even if it was a matter of knowing and not having any effect, Lu Fan also had to verify it, and the final truth was often a combination of several inconsequential small details.

Xiao Meng also seemed to have discovered this and nodded to Lu Fan.

The two of them retreated to the open-air staircase outside, still the same iron door and opening method, but now is not the time to take care of such a trivial matter, Lu Fan and Xiaomeng walked into the third floor together.

As a result, it was the same as the second floor, and the rhythmic sound was heard everywhere, this building had a total of six floors, and after carefully searching every room on the third floor, nothing was found, but it proved that the building was indeed resonating.

"Xiaomeng, the whole building vibrates together, I think there must be a vibration point that drives the whole" Lu Fan squinted his eyes and looked around.

Xiaomeng also expressed the same opinion, "Well, but it's not clear where the vibration point is, otherwise, let's check the whole building."

"Good!"

Lu Fan and Xiao Meng's eyes were full of excitement, and the two could be said to be on par in terms of curiosity, and Xiao Meng even licked her lips excitedly.

Step by step, they went upstairs.
