"Moreover, the source of the light is also very strange, the jade room is completely closed, where did the light we saw on the other side just now come from?" The excitement passed, and now all that's left was questions. （）

There was no light source in the jade room, and it was closed, the light from the outside couldn't shine in at all, the group was trapped, Tang San walked around like ants on a hot pot, his eyes stared straight at the jade ground, after looking at it for a long time, he suddenly said "Huh", the ground and wall of the jade room were actually made of jade bricks, and because the jade was a solid color, the gaps were almost invisible, and it looked like a complete plane.

Tang Sancheng studied the jade bricks on the ground for a long time, and realized: "This is the Nine Palace Grid." “

"Nine-square?" Xiao Ning also saw it, but he couldn't see anything.

The nine-square grid originated from the Hetu Luoshu, which is two mysterious patterns handed down in ancient China, and has always been regarded as the source of Heluo culture and the source of Chinese civilization, known as the "Cosmic Rubik's Cube".

According to legend, in ancient times when Fuxi, the Yellow River in Mengjin County, northeast of Luoyang, emerged from the Yellow River, carrying the "river map" and offering it to Fuxi. Fu Xi evolved into gossip according to this, and later became the source of "Zhou Yi". According to legend, when Dayu, Luoyang Xiluoning County Luohe River surfaced a turtle, carrying the "Luo Shu", dedicated to Dayu. Dayu succeeded in controlling the water according to this, and then drew the world into Kyushu. According to this, nine chapters were set **, governing the society, and it was handed down and included in the "Book of Shang", named "Hong Fan". "Yi Zhi Ci Shang" said: "The river produces a map, Luo produces a book, and the sage is a sage", which refers to these two things.

On the river map, the black and white dots arranged in several arrays contain infinite mysteries; The pattern on Vena Shu corresponds to nine numbers from 1 to 9, and the sum of the three numbers on the three lines is equal to 15, whether it is vertical, horizontal, oblique, or three, people did not know at that time, this is the third-order magic square in modern mathematics, and they call this mysterious number arrangement the nine-palace diagram.

"You're saying it's also a formation?" Xiao Ning asked.

"Sort of, you see, the lines on this jade piece don't look like numbers?" Tang Sancheng asked.

After a closer look, the lines on it really outlined the numbers, and Bai Yi asked, "Can it be broken?" “

"Wear nine shoes one, three on the left and seven on the right, two or four with shoulders, eight or six for the feet, and five in the center." Tang Sancheng read as he spoke, his feet stepped on the corresponding jade bricks, as the "Five Residences Center" fell, the ground of the jade room suddenly opened, except for the jade bricks that Tang Sancheng was standing on, all the jade bricks around him sank, and there was no trace in an instant, Tang Sancheng almost couldn't stand steadily, but he finally stabilized his figure, Xiao Ning was so frightened that he stretched out a hand to go over, seeing Xiao Ning's concern, Tang Sancheng was a little happy in his heart, and when his body stabilized, he looked down: "Bai Yi, you see, the jade bricks form steps when they go down, what a wonderful design." （）“

What's even more strange is that suddenly a light came out from underneath, as if someone below was holding a searchlight and hitting it upward, Bai Yi was a little puzzled, could it be that the light just now was this? So why is the light gone when you jump in? Could it be that the mechanism was inadvertently touched, so the nine-square grid will be restored, and the light will disappear?

Thinking about it, there is only one possibility.

Tang Sancheng was in a good mood, and jumped down without waiting for Bai Yi to speak, jumping onto the sinking jade brick, and Bai Yi was so shocked that he broke out in a sweat, the design here is exquisite, how do you know that this is not a trap?

Fortunately, Tang Sancheng stood there unharmed, and Bai Yi breathed a sigh of relief: "It seems that we are going down." “

Bai Yi also jumped down, there were only two people standing on a jade brick, and the two jumped down again, the seven evils and Xiao Ning also jumped down, leaving Lei Zi there to watch, his leg was injured, and it must be bearable to jump hard, but the others actually ignored him, and they all continued to jump down, he only let go, as soon as he closed his eyes, he jumped down, this jump, drove the wound, and the pain made Lei Zi bare his teeth. （）

Tang Sancheng and Bai Yi had already jumped down three times in a row, fortunately, the jade brick was made of jadeite and thick, otherwise Bai Yi was really worried that under this jump, the jade brick would be disconnected from it, and he couldn't see the situation below, in case it was an abyss, wouldn't he die too unjustly?

There were nine pieces of jumping, Tang Sancheng saw where the light source came from, and jumped down excitedly, but the ground was thin mud, as soon as it landed, the thin mud splashed all over his body, Tang Sancheng didn't have time to turn around to warn Bai Yi, Bai Yi also jumped down, the two stared at each other, Bai Yi turned his head: "Tang Sancheng, Tang Sancheng, let me tell you what's good." “

"You're jumping too fast, what can I do." Tang Sancheng learned to be obedient at this time: "Seven evils, Xiao Ning, there is mud down there, you should be careful." “

The two of them dodged away, this was another stone room, and when they saw the words on the stone wall, Bai Yi was stunned: "It's strange, isn't it true that the jade wall and this tomb have nothing to do with Zhuang Gong?" Is it all just a coincidence? “

"What's wrong?"

"Look at the words engraved on the wall, this is not from the Eastern Zhou Dynasty, this is the font of the Qin Dynasty...... Xiao Seal, the changes of the text in history are recorded, the Shang period: the popular text is the oracle bone inscription, that is, the text engraved on the tortoise shell or animal bones, about the Pangeng period. There is also a type of gold script, which is a text engraved on bronze objects, around the time of Zujia. These two also spread to the early Western Zhou Dynasty, but it is mainly based on the golden text, to the late Western Zhou Dynasty, there is a Zhouwen, also known as the big seal, is a kind of Jinwen, the historian of the Zhou Xuan King made a unified version of the different forms of the golden font at that time, and then became the official font of the Zhou Dynasty, until Qin Shi Huang unified the text for the small seal. After Bai Yi finished speaking, he pointed to the font on the wall: "This is a small seal, do you remember, on the bamboo slips we once found, there are characters with the same shape." “

"It's weird, on the other side is the tomb of Zhuang Gong's brother and his mother, why is this suddenly the tomb of the Qin Dynasty, this is really a big move." Tang Sancheng kept muttering.

"Could it be that Bai Yi looked at Xiao Ning, "The dispute between your father and his companion is actually because of this tomb?" Otherwise, why would they have a bronze key in their hands? Could it be that there is something here that they all want to get? Zhuang Gong hates his younger brother and mother, there will definitely be no funeral goods, let your father and his companions split, the reason is insufficient, the key opens the jade wall, and leads to here, I think, there is only one possibility. “

"That jade book was actually taken out from here?" Tang Sancheng was clever.

"That's right." The Seven Evils said in a deep voice, and he pointed to the stone wall: "Look, is there a piece missing here?" “

There is a missing part on the stone wall, just recessed, and the size is about the same size as the jade book, without any consideration, Bai Yi took out the jade book and put it on the stone wall, and the silk is not bad!

As the jade book was put in, the entire stone room suddenly made a loud noise, like someone beating gongs and drums in his ears, Tang Sancheng's hearing was originally better than ordinary people, and now this sound has had a great impact on him, you know, sound can also become a killing weapon, he covered his ears and shouted: "Mom, it's noisy, it's going to die!" “

Seeing that Tang Sancheng was uncomfortable, the Seven Evils quickly took out the jade book, and the earth-shattering sound disappeared immediately, and Tang Sancheng was returned to a quiet voice, the voice disappeared, Tang Sancheng recalled the movement just now: "Strange, the sound just now seems to be a knocking stone, and the sound of impact, like a ......"

"Construction?" Bai Yi asked.

"That's right, it's like construction, what's going on, this stone room seems to have been turned into a tape recorder, can it be able to record sound?"

"It's not surprising, there have been scientists who have found that in some remote mountainous areas, every time lightning and thunder, there will be the sound of war drums beating in the mountains, as well as the sound of horses fighting, scientists believe that stones also have a magnetic field, under the action of the magnetic field, there is a recording effect, this stone room may be the same reason, this jade book is like a switch of the tape recorder." After Bai Yi finished speaking, he looked around at this stone room, compared to the tomb room, this was a warehouse, because there was a row of stone boxes in the stone room, and there were stone locks on the boxes, one of which had been opened, could it be Xiao Tianyi and his companions?
