With a bang, the entire ice sculpture collapsed to the ground, and I was covered in cold sweat and my hair stood on end, and my heart swelled with fear.

Before entering the stone gate, we looked around the whole stone room, except for the ice sculpture of the prophet girl, there was no one else, and suddenly there was a human voice, and there was no one to see, it was difficult not to think that it was the ghost of the girl.

Was it because I accidentally smashed her ice sculpture? Or is it that her thousand-year-old lonely soul was locked in this ice sculpture and released by me unintentionally? How is that good, holding Sheng Shiyao's hand tightly, his heart is like a drumstick.

At this moment, fluorescent handwriting suddenly appeared on the ice wall, revealing word by word, and then erasing the traces, as if someone was writing in front of the wall. I couldn't be afraid, I felt that the message on it was important, and I stared at the ice wall, and when the last word appeared and disappeared again, the room returned to calm, as if the scene was an illusion.

But the things that those words tell are deeply imprinted in my mind, as well as this fantastic scene. opened his mouth several times before he found his voice that couldn't help but tremble: "This ...... What's going on? Is it the girl's lonely soul that is manifesting? ”

Sheng Shiyao said: "It's not a lonely soul, but this strange woman cleverly set up a mechanism to seal the sound in the ice sculpture, and then the cold air flow caused by the collapse of the ice sculpture caused the handwriting that was originally engraved on the ice wall sprinkled with phosphor appeared and disappeared." ”

"You mean that sound came from this ice sculpture?" I didn't even know what to say to describe my surprise, "But how could the voice be muffled?" Sheng Shiyao leaned down and picked up a piece of ice in his hand and said, "See?" The inside of this ice sculpture is formed by countless winding paths, like a maze that we have walked through, forming a three-dimensional loop, and then the sound enters from the beginning of the loop, and its propagation will follow the loop, and if it is closed in the middle of the loop, then the sound is sealed inside. The design of both the room temperature and the ice sculpture is carefully arranged, and the entire wall is enough to keep the room temperature below freezing point and prevent the ice sculpture from melting. But because its internal structure is empty, it is easy to shatter at the first touch, and when a crack appears, there is an exit to the circuit, and the sound comes out naturally. ”

The principle may be explained in a few words, but the inside of an ice sculpture has to be hollowed out to make a maze circuit, what a process this is!

Master, I've finally waited for you......

The words that the prophet girl had left in the ice sculpture just now were circling in my mind again, and then combined with the words that appeared on the ice wall, basically many things could be coherent. What appears on the ice wall is actually a letter left by the girl to the wizard, which roughly reads like this:

The master is above, and the apprentice Yingning is below. When you read this letter, the disciple is gone, but you would rather not regret it. Ning's life should have been killed by the catastrophe, but the master pulled Ning back to the world from hell at all costs. Then he took his own life to break the sky and look at the future generations, hoping to use the heavenly machine to save your body, and finally glimpsed that the purple jade can reduce your demonic nature, fortunately the heavens, looking for good jade refers to environmental protection and your life, only sighing that I can no longer see you. I would rather say goodbye to you here, hoping that it will be cherished.

After reading this letter, I learned that the prophet girl was originally called Ying Ning, and there was a deep sadness in the words, and the wizard violated the mandate of heaven in order to save her, and seemed to go crazy and become a demon, no wonder the eyes of the wizard in the second layer of the painting were blood-red, fierce and fierce, she couldn't bear to see the wizard like this, and finally opened the eyes of heaven with her life, seeking a way to rescue. The ring mentioned here should be the one I saw on the hand of the wizard in the painting before, the purple jade ring is demonic, it sounds very bizarre, but which thing is not bizarre now?

In this way, the wizard did not die in the end, and this Ying Ning eventually returned. is a very sad story, whether there is a relationship between the two that transcends the friendship between master and apprentice, they fight each other for each other's lives, and after all, they can't live together, and the two can only exist one. When the wizard woke up and saw that Ying Ning was dead, I don't know how he felt? I must have been overwhelmed with grief.

I didn't hear Sheng Shiyao speak for a long time, so I turned my head to look for him, and saw him standing in front of the ice wall with his back to me, I don't know what I was looking at so carefully, the handwriting on the wall was gone. I walked over and was about to ask, but I was shocked by what I saw, there was a person in white silk lying in the mezzanine of the ice wall, it was almost unrecognizable to see that it was Ying Ning, her hands were naturally bent between her waist and abdomen, her eyes were closed, and her expression was serene. But it was sour from the heart, because under her eyes, I don't know if it was the melting of the ice or some reason, tears slowly flowed.

Did she cry when she thought that the mechanism had been activated and her master had finally returned?

Inexplicably, sorrow starts from the heart...... I can't understand the origin of this emotion, and I don't know if I am sad for Ying Ning, or sad for her hope that she did not wait for her master. She predicted what would happen 500 years or even 1,000 years from now, but she could not have predicted that it was not her master who opened the door of life, but us who had nothing to do with her.

Wait, how did she get inside the ice wall? Is it an ice wall with a door that can be penetrated? But this ice wall is clear and smooth at a glance, and there are no gaps to be found, is it from the other side? He turned his head and wanted to ask Sheng Shiyao, but he saw that his dark eyes were staring directly at Ying Ning in the ice wall, without blinking.

I nudged him and asked, "What's wrong?" ”

He didn't move, his eyes wandering, "I have a very strange feeling." ”

"What does it feel?"

He shook his head and said, "I can't speak, I just feel tightness in my chest and a dull pain." Don't mention that, what did you just think of? I saw that he had diverted the subject, and without asking any more questions, I told him what I had just thought, and when I was done, I asked him, "Do you think there is a door on the other side of the ice wall or something, or how did she get in?" It's really strange that such a huge amount of ice is made into ice sculptures and ice walls, and I don't know where it came from, could it be that this place was very cold thousands of years ago? ”

As soon as his hand tightened, Sheng Shiyao grabbed my hand, "Ice sculpture and ice wall!" I know, Ying Ning's ice sculpture is a hint, she is signaling that there is a mystery in this ice wall, and it is likely that the doorway that can be drilled into is the way to the outside world. I'd have to take a look at the other side, and if nothing else, the door to the ice wall was on the other side. ”

I was taken aback, "Opposite? Isn't that the door of death over there? ”

Sheng Shiyao said calmly: "It's the door of death, I think we misunderstood the meaning of the door of life and death, the door of life may not refer to the road of life, and the door of death may not be the door of death." Xiaoxiao, wait for me outside, I'll go into the door of death alone to take a look. ”

"No," I instinctively objected, "to go and go together." ”

But he said: "No matter what is in the door of death, I can get out of it with my whole body, and if I bring you more, it will increase the obstacle, you are guarding me outside the door, just in case I am locked inside, you can still find a way." ”

His persuasive reasons were always irrefutable, and I had to listen. After the two of them exited the door of death, he asked me to stand by the stone platform while he walked towards the door of death. Looking at his long figure, I had an ominous premonition for no reason, and I called out loud: "Sheng Shiyao." He paused, turned his head to look, and I hesitated to speak, "Don't go in, we can find our way somewhere else." ”

After staring at me for two seconds, he said, "Trust me, it's going to be fine." Also," he paused, "call me Ah Yao in the future." ”

There was a black line on my forehead, when was this, he still minded calling it, but the tense atmosphere was diluted a lot by his words. watched him push open the stone door and step inside, although the door was not closed, but because it was too dark inside, even if he wore a night vision device, he couldn't see the scene inside, and only saw a puff of white gas coming out.

With the previous experience, I knew that it was caused by the cold air in it escaping out, and Sheng Shiyao was wearing a gas mask, so it should be fine. I sharpened my ears to listen, but I never heard any abnormal movements, and I breathed a sigh of relief, in fact, thinking back to this ancient castle all the way, although there will be mechanisms, but they are not the kind that hurt people, but hide some real events that have happened.

I kept an eye out for movement behind the stone door as I looked around, looking for any missing spots. When I looked up and saw the black-winged bat, now that both of its eyes had been removed, the red lens behind the eyeballs looked terrifying, and suddenly I remembered something.

Five hundred years ago, the founder of Huang Xingyuan's secret art (since I don't know his real name, let's call him Huang Xingyuan) also broke into this space like us, and then saw two green glass beads at the eyes of the bat and wanted to take them for himself, so he took them down. This stone platform slowly rose, and two grooves appeared, the left side was naturally empty, because the box was still hidden in the stone chamber of the green lake, and there was a silk book on the right, which he must have picked up and looked at before taking it away. It stands to reason that he would have taken two beads, so why did one of the beads end up in the bat's eye? This is the first doubt.

If it is said that when the two green glass beads are in the eyes of the bat, its mouth will spit out the stone ring, does it mean that Huang Xingyuan has actually seen those two layers of carvings? But I always feel that the stone ring mechanism in the bat's mouth is not so easy to reveal, and the two layers of carvings hidden on the bat's body must not be so much intended to be made public, otherwise there is no need to hide it so secretly.

Based on this theory, then it is possible that there is a mystery in the placement of the green glass beads in the eyes of bats, and it is likely that the order is different, and the mechanism activated is also different. In this way, maybe there are other secrets hidden in this bat, and after Sheng Shiyao comes out, he will tell him, and try to see again, maybe the blind cat will meet a dead mouse, and find some secret door to the outside world.

Thinking of this, I couldn't help but look behind the stone gate again, this Sheng Shiyao has been in for a while, why hasn't he come out yet? If there's no danger inside, why don't you call me in? If there is danger, he should come out, why is it quiet?
