He kept muttering, "How could this be," as he ran down recklessly.

"Hey, hey!" Xiao Xiao failed to stop Lao Zhang, so he could only watch Lao Zhang run into the darkness with the only flashlight.

The remaining three were dumbfounded.

"Why is he like this! We can't see anything without a flashlight. Zheng Qing'an was anxious and angry.

Xia Qingyang immediately instructed them to hold on to the wall to stand firm, so as not to accidentally fall down.

"Lao Zhang? Lao Zhang, you answer me! In the dark, Xiao Xiao held on to the handrail of the stairs and shouted a few times.

Didn't get any response.

At this moment, even the calmest Xiao Xiao panicked: "There is one thing to say, I think that killing is now. The corpse's kitchen is stronger than this ghost staircase......"

"Please, don't say it!" Zheng Qingan said that he did not want to hear it.

In the darkness where they couldn't see their fingers, the short breathing of the three of them was particularly clear and heavy.

Zheng Qingan sat down against the wall, and kept muttering about the ghost.

Xiao Xiao also tried to talk to the director team for help through the camera on his body, but unfortunately there was no response.

Feeling that his teammates' psychological defense line was gradually collapsing, Xia Qingyang raised his chin slightly, feeling that the time was almost up.

"Actually, darkness is not necessarily a good thing."

"What did you say?" Xiao Xiao's attention was not concentrated, and he didn't hear what Xia Qingyang said.

Xia Qingyang repeated: "For us, darkness is not necessarily a bad thing. ”

Zheng Qingan also raised his head. However, in such dark conditions, they could only see the fluorescent strips on their teammates' clothes, and they couldn't see each other's faces clearly.

Xia Qingyang explained: "Regarding ghosts hitting the wall, there is a saying that people's sense of direction is disturbed and they can't distinguish the direction clearly, so they will keep going around in circles in the same place. ”

Xiao Xiao: "I've heard this. I've also heard people say that when you encounter a ghost hitting the wall, you close your eyes and walk by feeling, and maybe you can get out. But we're on the stairs now, not flat ground, so we don't meet the conditions. ”

"It's better to try than to wait."

Xia Qingyang's words seemed to have magical power, which inexplicably comforted the two teammates.

Why don't you just try?

It's just a black light, and it's no different from having your eyes closed.

"Yes, yes." Zheng Qing'an hesitated for a moment, stood up and said, "I have also heard of a method, saying that in this case, singing red songs will be more likely to drive away evil spirits...... Shall we give it a try as well? ”

Red Song?? Xiao Xiao choked, and just said don't make trouble, but Xia Qingyang actually said that she had also heard this statement.

"That's it, let's grab the handrails and go up while singing red songs together, and see if we can get out." Xia Qingyang made the final decision.

Xiaoxiao: ......

is another two-to-one advantage, Xiao Xiao can only obey.

After choosing a good song and starting to sing, the two female guests knew why Xiao Xiao was reluctant-

Because he's a sound idiot.

And it's not your average music nerd.

“…… My motherland and I can't be separated for a moment~cut~"

As soon as Xiao Xiao sang, Zheng Qingan covered his head with a headache: "To be honest, I think the motherland wants to separate from you after hearing it." ”

Xia Qingyang affirmed: "Exorcising evil spirits, very exorcism." ”

Xiao Xiao felt a little aggrieved in his heart, but it's like this anyway, so break the jar and continue singing.

"My motherland and I can't be separated for a moment ~ cut ~

Everywhere I go, there is a praise ~ song ~ ……”

The trio formed a temporary choir that was not very tacit, and while singing, they tentatively took steps upward.

Not to mention, singing red songs really works.

Probably because the lyrics and tunes are full of righteousness, after singing it aloud, the fear in my heart was suddenly shaken away. There is even a bit of an urge to go on the field to kill the enemy and defend the country.

After discovering this effect, Xiao Xiao was a little happy to sing louder and louder.

Xia Qingyang understood at this moment what it meant to have a magic sound and what it meant to ask for hardship.

Regret, the person concerned just regrets it very much.

Thankfully, they quickly came to an end.

"Stop." After Xia Qingyang stepped up the last step of the stairs, he stopped, "I touched the corner of the wall, we should have walked up." ”

"Huh? But I haven't gone a few steps. ”

Xiao Xiao and Zheng Qingan both couldn't believe it.

They hurriedly followed Xia Qingyang's footsteps and walked up to the last step.

The faint moonlight poured in through the dusty window, allowing the three of them to finally see a little light.

It was finally confirmed, and this should be the second floor.

"Good fellow, it's kind of coming up." Xiao Xiao let out a sigh and wiped the cold sweat from his face, "By the way, I figured it out, what we just experienced may be the legendary 'Penrose Ladder'." ”

As soon as he arrived in a safe place, Xiao Xiao's brain was running again.

The Penrose Ladder, also known as the Penrose Ladder, is a ladder that always goes up or down and never reaches the end, and is also a famous geometric paradox.

It usually takes the form of people going in circles forever, going up forever, only to go back to square one over and over again, which is really similar to what they just experienced.

"But I remember that the Penrose Staircase was a plane trick that took advantage of poor human vision and could not have been realized in a three-dimensional world." Xia Qingyang touched his chin thoughtfully, directly piercing Xiao Xiao's confidence.

Xiaoxiao: ......

He just wanted to find an explanation to comfort himself! Don't be so serious! Do you really have to admit that they were ghosts hitting the wall just now?

"Hey, I don't understand those advanced ones, anyway, now that I've passed the test safely, it's better than anything else." Zheng Qingan waved his hand, "If you want to find clues, just look for clues, I want to find a place to rest first." ”

With that, she turned around and went to find a chair or couch to sit on.

At this moment, Xia Qingyang suddenly grabbed her arm.

Zheng Qingan was startled, and was about to speak, when she saw Xia Qingyang "shh

Following Xia Qingyang's gaze, Xiao Xiao also looked behind Zheng Qing'an.

Then, as if he had seen a ghost, Xiao Xiao was full of excitement-

I don't know when, just behind Zheng Qing'an, a doll with loose hair and a dirty skirt appeared.

I saw the doll tilting its head, looking directly at Xia Qingyang and Xiao Xiao with its pair of black eyes.

The appearance of the doll is exactly the same as described in the diary.

"What's wrong with you two?" Zheng Qingan didn't know why the two people in front of him suddenly seemed to have pressed the pause button, neither making a sound nor moving.

Is there something behind her?

"Don't look behind...... Xiao Xiao's reminder was still a step late, and Zheng Qingan had already turned his head to look.

Then, unsurprisingly, there was a scream that pierced the sky:

"Ghost, ghost!"

With Zheng Qing'an's scream, the doll's eyes suddenly turned from black to red, her hair became longer like a waterfall, and she threw herself at the three of them with a cruel smile.

"Come play with me——!!"
