That fake Moon Shadow Fuxian had deliberately approached Wu Zhiyuan, wanting to get the whereabouts of the treasure map, it seemed that all of this was for the treasure map, could it be that they imprisoned the Moon Shadow Fuxian and wanted to use her as a threat?

Thinking about it, Wu Zhiyuan felt that there was only one possibility. After a moment of silence, he jerked to the Moon Shadow Immortal and asked, "Do you have any twin sisters?" ”

Hearing Wu Zhiyuan's question, Moon Shadow Fuxian couldn't help frowning, she pondered for a moment and replied, "I was picked up by my master from the shore of Fuxian Lake, and I told you about this before. When I grew up, Master never told me about my life or any relatives, and I don't think she knew anything about it. ”

Wu Zhiyuan thought about it, and felt that the fake Moon Shadow Fuxian was exactly the same as the real person in terms of appearance, figure and even voice, if it wasn't for the fact that he discovered her virgin body, I am afraid that he would be kept in the dark in this life. If these two people are not the same mother, can there be other methods of transfiguration? Then he asked: "Do you know that kind of disguise technique in this world, which can make two people look exactly the same in body and voice?" ”

"Transfiguration?" Moon Shadow Fuxian said softly, and at the same time reached out and lifted the steel ring around her neck, the steel ring was very heavy, and her shoulders were a little unbearable after sitting for a long time, she continued, "Legend has it that there is such a disguise technique, which can make two people's bodies look exactly the same, but if you want to make two people's voices exactly the same, I'm afraid it will be difficult to do it. ”

Wu Zhiyuan nodded, and did not continue to ask, he sat down next to Moon Shadow Fuxian, and reached out to lift the steel ring on her neck, wanting to relieve her of the pressure on her shoulders, this steel ring weighed dozens of catties, made of pure steel, and it was extremely hard.

"If the Yuan Qi cultivation reaches a certain level, you must be able to break this steel ring with your bare hands, but it's a pity that it's ......" Moon Shadow Fuxian looked down at the steel ring around his neck, his expression gloomy, and his words came to an abrupt end here.

"What a pity?" Wu Zhiyuan faintly felt that there was something wrong with Moon Shadow Fuxian's words.

"It's a pity that my vitality cultivation is not enough, and I can't do anything about this steel ring." Moon Shadow Fuxian sighed.

As soon as she finished speaking, Moon Shadow Fuxian grabbed Wu Zhiyuan's hands, her expression suddenly became excited, her eyes were moist, and she said eagerly: "Brother Zhiyuan, you better go quickly, I have this thing around my neck, I can't get out of this pit no matter what, you go, leave me alone." ”

Wu Zhiyuan hugged the Moon Shadow Fuxian, stroked her back, and said softly: "In this life, the two of us will die together, you see this pit, closed on all sides, only there is an exit at the top, but the mechanism is outside, and now it is tightly sealed, we won't go out at all." ”

Before Wu Zhiyuan's words fell, Moon Shadow Fuxian's hand shook violently, she pushed Wu Zhiyuan away, shrank back against the wall, and said in a loud voice: "There is a way, there is a way out!" ”

Wu Zhiyuan didn't know where to go, but when he saw the Moon Shadow Fuxian, he reached out to get the torch on the ground not far away, but his body was imprisoned by a heavy steel ring, and he was restricted by chains, so he tried it but couldn't reach it, Wu Zhiyuan hurriedly went over and picked up the torch and walked in front of the Moon Shadow Fuxian.

"Look here!" Moon Shadow Fuxian grabbed Wu Zhiyuan's hand holding the torch, brought the torch under the wall with a large gap at the bottom, and pointed it with his hand.

Wu Zhiyuan fixed his eyes and saw that there were a few words at the bottom of the wall near the edge of the big gap, the font was seal script, carefully identified, and found that there were four words, each word was the size of an adult's fist, arranged up and down, carved into the wall stone deeper, and it was vaguely recognizable over the years.

Wu Zhiyuan didn't know much about seal script, this font had been rarely used a long time ago, and it could only be seen in calligraphy works.

Wu Zhiyuan muttered out, but he didn't recognize the first word no matter how he looked at it, he looked at the Moon Shadow Fuxian, who narrowed his eyes and stared for a long time, and suddenly said a word: "Wall!" ”

"Wall?" Wu Zhiyuan was stunned for a moment, and immediately recited together, "Outside the wall? What does that mean? ”

"I'm not very sure if this word is the word 'wall', but I also recognize the three words 'outer heavenly machine', and judging from these three words alone, I guess that there must be a hidden heavenly machine outside this stone wall, maybe it is the exit, the person who left the word here is hinting to later generations, this stone wall is the weakest, is the exit of this pothole."

Wu Zhiyuan listened to Moon Shadow Fuxian's words, glanced at this wall in disbelief, and found that this wall was no different from other walls except for a large gap at the bottom near the ground that could be climbed into, how could it be said that this wall was the exit? Besides, there are no stone cutting tools today, and this wall is undoubtedly a dead end.

"Look at this wall is no different from other walls, not to mention who left the words, what the words he left meant, we have no way of knowing, just guessing out of thin air, I'm afraid it may not be correct." Wu Zhiyuan voiced his concerns.

"The person who left the words will never harm us, otherwise he would not have done such a meaningless thing in the last moments of his life." Moon Shadow Fuxian said categorically.

Wu Zhiyuan was stunned, not understanding the meaning of the Moon Shadow Fuxian's words, and asked, "You mean that the person who carved these four words died in this cave?" As he spoke, he looked down at the nearby bones, and suddenly noticed something like a hammer under the fragmented bones, and hurriedly bent down to pick it up.

This is really a hammer, the hammer handle is a whole body, all iron, I don't know how many years have passed, the surface of the hammer has a thick layer of rust.

"This hammer also proves their identity." Moon Shadow Fuxian said slowly.

"They...... Who are these dead people? Why are the corpses piled up here? Wu Zhiyuan asked puzzled.

"They are the craftsmen who dug this hole and even the so-called 'extra-wall machine'." Moon Shadow Fuxian said, "They completed their mission, and then they were brutally slaughtered by their masters, and then their corpses were dumped, and this is the place where the corpses were dumped. ”

When Wu Zhiyuan heard this, he looked around at the situation in the pit, and saw that white bones were piled up everywhere, which was extremely miserable.

"According to the four words on this stone wall, I guess there must have been a person who did not die at that time, and before he died, he carved these four words on this stone wall, because he expected that someone would definitely enter this corpse pit in the future, so in order to take revenge on his master, he divulged the heavenly secret outside this pit."

"It's not very reasonable, how could that craftsman have predicted that someone would fall into this hole in the future?" Wu Zhiyuan questioned.

Moon Shadow Fuxian smiled slightly, although her face was pale, but still delicate, she said softly, "Because outside this pit is a tomb. ”

"Grave?" Wu Zhiyuan asked in surprise.
