I looked at it several times and made sure that there was no clerical error on Monceau's drawing of this spiral staircase, because the whole spiral ladder was drawn with great precision, and it was clear that Monceau was careful and careful enough when drawing it.

There must be a reason why the spiral staircase in the castle is broken, and the spiral staircase here is too deep.

I heard Yunshang say on the side: "Didn't we find a paper roll from the prison cell, take it out and take a look, I'm still curious about what is drawn on it, or what is written." ”

I smiled at Yunsheng: "Why is my girl so talkative today." ”

Given that we are not in a safe environment, we need to be as silent as possible in order to better hide ourselves.

But since she entered the reverse city, Yunshang has often tried her best to find topics to talk about, which is not like her usual appearance at all.

Yunshang naturally understood what I meant, she sighed, and said with some concern: "I don't know what's wrong, since I entered this place, I've been worried for a while, I've never been like this before." ”

In this reverse city, there must be something that can affect Yunsheng.

I still smiled at Yunshang: "Don't worry about it, maybe you've been too tired lately, and you can't adapt to it mentally." ”

Yunshang pouted: "I'm okay, since you entered the Inland Sea, you have been spinning continuously, and you have never rested from beginning to end, sometimes I am really afraid that you will exhaust yourself." ”

I felt that Yunsheng should not have finished her words, because at the end of these words, she suddenly turned her head quickly and looked towards the doorway behind us.

"What's wrong?" I saw that her face was a little surprised, so I asked casually.

Yunshang frowned slightly: "Just now, there seemed to be a very loud sound in this doorway, but I didn't really hear it." ”

Isn't it a contradiction that it is a very loud voice, but it is not really angry?

What's more, I didn't hear any loud noises at all.

At this time, Yunshang took the initiative to explain: "That's it, that is, it seems to be a very small sound, suddenly amplified, and it seems to be a very loud sound, and it suddenly becomes weaker, oops, I can't tell, anyway, the voice is very unreal, it seems to have appeared, and it seems to have never appeared." ”

Seeing that Yunsheng's face became more and more anxious, I reached out a hand, lightly placed it on her wrist, and comforted: "It was a dark sound, and I heard it too." ”

Between words, I probed Yunsheng's meridians with my hand, and her meridians and soul were very stable.

OK.

Yunsheng's eyes widened and asked me, "Uncle Xiao, you won't be lying to me, did you really hear that voice?" ”

I flickered seriously, "Of course I heard that." Girl, do you remember when we first entered the Inland Sea, those illusions we saw, they seem to be real, but in fact they are all virtual, in this reverse city, there is also a power similar to the whispering of the deep sea, it will affect people's minds, make people hallucinate, you must remember, but everything that is not real, ten ** are illusions, don't be confused by them. ”

Yunshang nodded: "I understand." Uncle Junior, did you hear a commotion just now, like the sound of a bunch of keys colliding with each other? ”

As soon as I heard the words "what you just heard", I knew what Yunshang was going to say later, so in order not to reveal the stuffing, I took advantage of the stall where she was talking and reached into the backpack with my backhand, and found the metal box containing the paper rolls from inside.

Can't let Yunshang know that she is the only one who can hear the sound, otherwise she will be even more nervous.

For example, when you are walking at night, you see a woman in a white dress standing in front of you, and you think that woman is very strange, so you ask your companion, "Hey, do you see that woman?" As a result, your companion said: "There are only two of us on this road, where did the woman come from?" ”

Come on, feel it, this feeling is not particularly devastating.

As soon as Yunshang finished speaking, I carefully unfolded the paper roll.

I saw that only a very short sentence was written on this eighteen-open old paper: Don't look back!

It was written in English, and each letter was large and the handwriting was very distorted.

Looking at the words on the note, Yunshang and I both had doubts on our faces.

Don't look back, what do you mean? Why did the man who escaped from the cell leave such a passage, and to whom was this passage for?

Knock, knock, knock, knock......

Here Yunshang and I were frowning at the words on the note, and at this moment, a dull footstep came from the doorway.

This time, the voice is very solid, and it should not be an auditory hallucination.

Yunshang looked at me in surprise, and I made a silent gesture at her, then quickly put away the note and map, and pulled Yunshang to hide by the doorway.

Judging by the sound of footsteps, it should not have been the evil corpse I put down to wake up, and when it walked, it was much louder than that.

After waiting for three to five minutes, a slender figure came out of the doorway, and when I looked closely, it was one of the prisoners, and in his hand, he was still holding a bunch of keys that hung on the corpse.

I immediately reacted that the sound Yun Sheng had heard before was not an auditory hallucination, but the sound of the prisoner snatching the key from the corpse.

It was so strange that Yunshang could hear the sound of keys hitting each other at such a distance.

Yunshang's sense of hearing seemed to be suddenly strengthened at that moment.

The prisoner has lived in the dark for a long time, and it is said that his eyes are no longer able to adapt to the light on the spiral staircase, and such light can make him lose his sight for a long time at least a flash, but strangely, this guy adapts to the bright light faster than me, and after he rushed out of the hole, he was stunned for only two seconds, and then he fell on all fours and crawled towards the bottom of the spiral staircase.

I felt as if he was going to save someone, otherwise why would he take the jailer's key with him on the way out?

Don't look at his limbs are almost dry, but the crawling speed is quite fast, in the blink of an eye, he jumped out for several meters, I quickly thought about it, and decided to follow him to see the situation, so I pulled Yunshang and chased after him quickly.

About every time you run down the spiral staircase for more than 50 meters, you can see an arched doorway in the wall, and in each doorway is an empty room, but there are no evil corpses in the room.

Repeatedly encountering these incomparably similar doorways along the way gives a feeling of constant repetition.

It's like encountering a ghost hitting a wall, no matter how you go, you end up spinning in the same area.

At that time, another impulse floated in my heart, which was to look back and see the way I had been.

As soon as this impulse appeared, the words on the note quickly appeared in front of my eyes: Don't look back!
