Ziru said: "I'm not sure either. Since you say you want to retreat, go back the way you came, and see what happens. ”

Wet Wind looked up at the entrance to the upper floor, sighed, and said, "This is easy to do." Let's go. "Stand up and turn around.

Back at the entrance, Ziru said, "See if your mark is still there?"

Wet Wind took a few steps forward, and his finger touched a waist-high spot on the wall, and said, "It's still there." ”

There was a faint carving of a small flower, the same one that had been struck on the skull before. Ziru snorted and said, "Let's take a look at the next floor." ”

The three of them jumped down from the gap, passed through the corpses, and walked to the corridor, where they groped for a while and found a mark at their waists.

Ziru said: "Go down again." ”

One more level down.

This time, I searched for a long time, but I couldn't find a mark.

Others helped to find it, but there was none.

Mao Feng wondered, "Could it be that I forgot to mark this layer?"

Ziru's expression seemed to be a lot more relaxed, and said, "It's possible." Then move on. ”

One level down, there is still no marking.

Mao Feng scratched his head and said, "No, I forgot about this layer?"

Canghai said: "Brother Feng came up in a hurry just now, and it is normal to have occasional omissions. ”

Mao Feng said: "Strange, I have the impression that I should have hit every floor." ”

Ziru said: "It's only three things, and the next layer will know the end." ”

The three of them continued to walk down.

This is the fourth level downward. The three of them searched back and forth on the wall of the corridor several times, but they could not find even a trace of a mark. As if realizing something, Mao Feng said, "This is not right, I will never forget to mark three floors in a row." ”

Canghai said: "Why don't you go down and take a look?"

Ziru said: "I guess it's the same below. ”

Canghai was stunned for a moment and said, "You mean, there are no marks below?"

Ziru said: "Probably so. ”

Canghai knotted his eyebrows and said, "Why have all the towers that walked back have changed?

Mao Feng stared at Ziru and asked, "Are you sure there is no one down there?"

Ziru said while tapping along the wall: "I'm not sure, I guessed too, but I believe there is no one below." If you don't believe me, you can go down and find out. ”

Mao Feng really ran down to check. After a while, he ran up again, expressionless.

Canghai asked, "Brother Feng, is there any below?"

Before Mao Feng could speak, Zi Ru said: "No need to ask, just look at his appearance." ”

With a little sadness on her face, she saw her banging non-stop, and said, "What are you knocking?"

Ziru said: "Knock on the sound." ”

Mao Feng was a little confused, and said, "Knock on the sound, knock on what sound?"

Ziru said: "You can knock anything, as long as there is a sound." ”

The wind leans to the wall and listens. Canghai's curiosity rose, and he also attached his ears to it. I listened to it for a long time, but I didn't hear a reason. Mao Feng said: "Do you think there is a secret path here?"

Ziru said: "No." ”

"Then what are you listening to?"

Ziru said: "Spread the voice." ”

Mao Feng said: "What can you hear?"

Zi Ru said: "My Tianji Gate has a technique of listening to sound and distinguishing shapes, which can distinguish the shape of sound within a certain range according to the direction of its propagation in an object. You haven't learned, and of course you can't hear it. ”

Mao Feng said: "Then what did you hear?"

Ziru said: "The voice is vague and unclear, and the transmission is short and easy to break. ”

Mao Feng thought that she would tell some shocking truth, but when she heard it, she was immediately deflated, and pouted: "Cough, after talking for a long time, it's just useless." ”

Zi Rubai glanced at him and said, "You always think I'm useless." ”

Canghai was curious: "Why did Miss Ziru suddenly think of listening to this wall?"

Ziru said: "When you were talking above just now, I suddenly thought of something. ”

Canghai said: "What's the matter?"

Zi Ru said: "Since entering the tower, all kinds of strange changes in the tower are difficult to deal with with common sense. We've been obsessed with the structure and mechanics of the tower, and we've always wondered why these changes could have come about, but even the most skilled craftsmen can hardly do anything with such unpredictable mechanisms. So then you said a word, but you inadvertently reminded me. ”

Canghai scratched his head and thought about it, he really couldn't remember what meaningful words he said, and said, "What did I say?"

Ziru said: "You say, it's like a nightmare. ”

Canghai was stunned for a moment, then smiled embarrassedly and said, "I just said it casually." ”

Ziru Zhengse said: "No, what you said is probably right. ”

Canghai saw that she was serious, not like she was joking, but she couldn't understand it for a while, and said ignorantly: "This ......"

After all, Mao Feng has known her for a long time, and she knows her better, and as soon as she said it, she said, "What she said was an illusion." ”

Canghai was stunned and said, "Illusion? Is it the mirror image method of projection?"

Ziru said: "It's different from the mirror method. The method of mirroring is just a simple visual illusion that can be seen but not touched. The illusion we are in now is all-encompassing. Sight, hearing, smell, touch, all of them are like in a dream. Although everything is not real, when you dream, what you see, smell, hear, touch, those feelings will be fed back into your body as if they were real. ”

Canghai's eyes widened in surprise, and he reached out to touch the cold wall, felt the real touch, and said, "This is ...... How could it be, it's too real. ”

Ziru said: "It should be said that this is the most likely, otherwise such a strange situation today cannot be explained in reality." Perhaps, from the very beginning we overlooked one thing. ”

Canghai said: "What's the matter?"

Mao Feng said: "It's a three-star Dou Phantom Moon Array." ”

Ziru clapped his hands and said, "That's right, Brother Maofeng, you finally want to be with me." ”

Canghai said: "What do you mean by this? ”

Ziru walked to the group of corpses, pointed to the location of the three formations on the side of the tower and said, "The reason why we fell into the illusion realm is because the three-star one-bucket phantom moon array in this place is still in an active state, and we were hit as soon as we came in." ”

Canghai was stunned for a long time, and said, "...... them Isn't the caster already dead? Besides, this was more than a hundred years ago, how could that three-star and one-bucket Phantom Moon Array still be activated?"

Ziru said: "Have you forgotten how you discovered this place? Although the people are dead, their will is still there." ”

Canghai muttered: "I see, I understand. So, we've been in a fantasy all along?"

Ziru said: "I think it should be." All that happened in the tower only made sense if he was hit by the Phantom Moon Array. It's all because we were too careless, we didn't think about it in the first place, and no one expected that more than a hundred years after their death, the formation would still be effective. ”
