Altar? Needless to say, the stone tool in front of me must have existed in ancient times, and I immediately thought of the kind of activity that was sacrificed with fresh life, and I couldn't help but feel a chill in my heart.

But I heard Sheng Shiyao say: "It's not what you think, this altar is not used for sacrifice, and there is no resentment on it." It is a celestial altar that rotates every few minutes, producing some kind of magnetic induction that causes the medium in the air to change. As for the utility of its existence, and why it is in this cave, I still can't figure it out. ”

Hearing him say this, the choked breath in his throat was finally smoothed, but don't tell me what kind of resentful spirit is operating when the stone tool turns on its own, it will be really terrifying. Sheng Shiyao suddenly walked towards the stone tool, so frightened that I hurriedly grabbed him from behind, and just when he looked back at me, the copper-like flashlight in my hand shone on his face, and his gaze fell on it.

"What is this? Where did you get that? ”

I handed it to him and replied, "That's what I found here, I guess it's a flashlight or something, but it's so exquisitely made that it doesn't rely on electricity, but on the heat energy generated by rotational friction, which causes the metal on the head to glow." ”

After he took it, he looked at it for a while with the pill flashlight he brought, and finally concluded: "This is an antiquity, the copper on the outside belongs to bronze, but the metal of the lamp head has never been seen, I don't know what material it is." Normally, metals emit light by heat and the temperature reaches 10 percent, but this metal emits light only by the heat generated by rotational friction, and the surface of the metal is not hot, which is really unbelievable. ”

It was rare to hear him praise something like this, and I couldn't help but ask with some excitement: "That means I have chosen a treasure?" ”

But he splashed me with cold water: "Whether it is a treasure or not remains to be confirmed, for the time being, you can put it away for the time being, use the flashlight to light it first, and then use it when the battery runs out." I silently put the object in my pocket.

Sheng Shiyao was about to walk towards the stone tool again, and just as he was about to stop it, he heard him say: "If we don't study it, we won't be able to get out." ”

My heart sank, and I asked in surprise, "Why can't I get out?" Didn't you just come in? "I had experienced his ability to tear apart the rift in the miasma area of the Dian Island cave before, so when I saw him emerge from the crack in the wall just now, I didn't ask for details except for shock, it should be that he followed the soul sound to find this place, and then also used the secret technique to tear open the rift. His soul sound, the object of use is not me, it is Shadow Moon.

"I can come in because you and Shadow Moon are in this rift space, and they can sense me, and now that I'm here, who is on the other floor to sense me?"

The reason is so simple, that is to say, he also fell into this predicament in order to save me.

Sheng Shiyao squeezed my palm and said lightly: "It has nothing to do with you, you don't need to blame yourself, I was careless, I thought this cave was nothing special, so I let Zhou Tong come in to hone it, but I didn't expect that there was something hidden inside." And since this altar can disturb people's minds, even if you stay at the entrance of the cave and don't follow up, you will be attracted to it by a certain magnetic force it creates. ”

As he spoke, he approached the stone tool, but not too closely, but stood on the periphery and watched its movement with a flashlight. As I stood next to him, I noticed some patterns on the stone plates, and I couldn't help asking, "What is that?" ”

"Sacrificial symbols. The celestial altars of each dynasty had special symbols that represented the language of communication with the gods to be worshipped. ”

I remembered that he was also a shaman in his previous life, and he must have presided over rituals, so he was familiar with these cultures. I don't know that he might read this symbol, but I heard him deny it in a low voice: "I can't read it, because every wizard has his own unique way, unless he is a member of a race, he can follow the sacrificial symbols of his predecessors." ”

"Could it be that the rotation of this stone tool has something to do with the sacrifice?"

Everything has a cause and effect, and it is impossible for a thing to run on its own for no reason, even Zaixuan's magnetic field theory must follow a certain law. The behemoth in front of him, which rotated every few minutes, was not driven by a wraith, so it must have been for some reason.

Sheng Shiyao pondered for a moment, "And wait for me to observe carefully before making a judgment, you must remember to follow me and don't leave even half a step." I nodded vigorously and grabbed his hand tightly for safety. He slowly walked around the stone tool with me, and when he saw a few white bones in the ground, he paused, but he didn't stay long, and continued to start. Until a week of detouring, when I returned to the original point, I didn't see any other white bones.

Because I was standing on the periphery, I didn't know much about the periphery of the stone tools, so I could only stare at the position of the chassis, but I found some clues. It seems that at the very bottom of the archetypal stone tool, at the four corners of the opposite side, there is a pattern carved with a fist-sized figure that is also round. But the light was too dim for me to see what the pattern was.

After Sheng Shiyao stopped, I told him what I had found, and his eyes focused on the bottom, and the natural light also focused there, and then I saw the pattern clearly, and it turned out to be a little gossip. I only heard Sheng Shiyao's slightly surprised voice: "Five elements gossip? ”

I instinctively retorted, "Where are the five elements?" Aren't there four gossip patterns at the bottom? ”

But I saw him raise his hand and shine the flashlight on the center of the real plate, "The fifth one is there." "I stood on tiptoe and looked around, and sure enough, the gossip was much bigger than the bottom four, but because of the light and angle, it was not easy to be spotted at a glance.

"Xiaoxiao, have you ever heard of the gossip of the five elements?"

I looked sideways at him, and saw that his face was deep, and he was going to test me again? After thinking about it, he replied truthfully: "I only know that the five elements are gold, wood, water, fire, and earth, and I can't remember the gossip clearly, but I only remember the three trigrams of Qian, Kan and Kun." "I've never studied any of this scholarship, but I just know something about it out of common sense.

He whispered: "The five elements are indeed the five things of gold, wood, water, fire, and earth, but this is different from the matter we usually know, this line represents the 'kinetic energy', and the forms that express kinetic energy are these five kinds. As for the gossip, it is actually a continuation of the five elements and yin and yang, which is Qian, Kan, Gen, Zhen, Xun, Li, Kun and Dui, or divides all things into eight trigrams.

The original of Bagua was Wuji, and Wuji refers to the land of chaos. Legend has it that Pangu opened the sky, split the infinite, the light rose, the heavy fell, and then there were two yi, and the two yi also refer to the two qi of yin and yang, yin turned into water, and yang was fire, so water and fire are the essence of the two qi. Then down is the four directions, the four sides are two by two into the image is the four elephants, and the four sides plus the four elephants become the gossip, which is the origin of the five elements of the eight trigrams. ”

After listening to it, I couldn't help but sigh, "You know so much." ”

A low chuckle came, and he raised his eyebrows slightly: "The Book of Changes is the most basic course in Feng Shui, and the Five Elements Bagua is very useful for the position and side hexagrams, as well as Feng Shui, so I naturally understand it." Soon he changed his tone again, frowned and said, "It seems that this heavenly altar is very mysterious, and the way of this hexagram is very strange." The main hexagram is at the top and the secondary hexagram is at the bottom, in order to borrow the main hexagram to control the sub-hexagram, is it said that its self-rotation is because of the five elements of the eight trigrams? ”

I can only say that I can't help this, and while he was meditating in that time, his eyes wandered to see if there was anything else to discover, and inevitably noticed the white bones underneath. Hey? What is that?

I pulled Sheng Shiyao and motioned him to see that there seemed to be something in the corner behind the bones. The light gathered, a little far away, and only a black mass was seen, but there was indeed an entity there, and after a few steps closer, it could be recognized, as if it was a sheepskin bag. Maybe it's because it's been put for a long time, not to mention the ashes, and it's become a black mess.

Theoretically, it is speculated that this sheepskin bag should belong to one of these five people, and it is also a loss of skin, if it is a cloth bag or something, it must not all be corrupted. Just look at the corpse completely corrupted into white bones, and there are no clothes left, it should have been many years.

Sheng Shiyao wanted to squat down in place and untie the sheepskin bag to check, but I looked at the white bones next to me and felt really uncomfortable, so I suggested that he take it aside and look at it again. He looked at me, but didn't say much, just picked up the leather bag and went to the side, and then untied the mouth and poured out the contents inside.

It was found that there were scattered objects inside, some of which were suspected to be carved knives, there were parchment booklets, and a few charcoal pens, and the rest were small objects, and one of them was a round copper object that was very eye-catching, and was almost immediately picked up by Sheng Shiyao to inspect it. I couldn't help but ask, "What is this?" You can see that there seems to be a pointer pointing downwards on it, and the periphery of the circle is divided into small squares, each of which is engraved with words. I can understand these words, only a few words are mixed with traditional Chinese, and even Meng Dai guessed that it should be the words of the sexagenary.

"It's the compass."

Compass? I've seen him measure Feng Shui with a compass, his one is boxy, there is a circle in the middle, and the circle is densely distributed small characters, and in the middle is a small compass-like thing, which is so simple?

After a pause, he explained in a low voice: "Judging from the text and shape, this should be a copper compass from the Ming Dynasty, and the words engraved on it are twenty-four directions. His gaze swept the ground and fixed on the mouth of the skin, where a round wooden box had tumbled. With a slight rotation, the lid opened, and when I looked into it, I realized that it seemed to be a compass as well.

In the center of the wooden box is a deep circular groove with water in it, and there are 24 places around the disc like a copper compass. After Sheng Shiyao took a closer look, he nodded and said affirmatively: "That's right, this is the Ming Dynasty navigation sea compass, and the small objects on the ground are all some navigation necessities." The reason why sheepskin bags are used for stuffing is also because the sea is so humid that things can't get wet. If I'm not mistaken, these men should be the crew, and maybe even one of them is the captain, and this sheepskin bag belongs to him. ”

I couldn't help but turn my eyes to look at those white bones, I thought it should have been many years earlier, but I didn't expect it to be traced back to the Ming Dynasty, wouldn't it be five or six hundred years ago.
