At this time, Lu Ji sat on the edge of the octagonal well circle in the center of the patio, and he took the Tibetan scripture map handed over by Yi Susu and looked at it carefully. The Tibetan scripture picture is painted on a yellow silk cloth, and the picture is drawn on an acquired gossip, and there is a line of words written below: the ninth day of the first month, the hidden dragon should not be used.

Lu Ji pondered for a long time, and it seemed that it was just an ordinary gossip diagram and a sentence from the Book of Changes, which was the most common sentence for people who had come into contact with the Book of Changes, and they couldn't see the mystery.

At this time, Yi Susu, who was on the side, saw Lu Ji sitting on the edge of the well and was fascinated, afraid that he would accidentally fall into the well, so he reminded: "Mr. Lu, you have to be careful, don't fall into the octagonal well." ”

"Octagonal well..."

As soon as Lu Ji heard these three words, he immediately stood up and carefully observed the octagonal well.

"The general well circle is either round or hexagonal, why is this well octagonal?"

Gongsun Yu has always felt very strange, in fact, Lu Fu also thinks it is strange, so Gongsun Yu said: "I remember that when I was in Phoenix Market, Brother Lu also asked Master, but Master did not answer this question at that time."

Lu Ji seemed to be ignited, and looked back and forth around the mouth of the well, which was in an octagonal shape, about five feet wide, and about two feet wide on each side. Suddenly, I saw him slap his right leg vigorously with his right hand, and said loudly: "Yes, brother, Su Su, you come and see." ”

While beckoning Gongsun Yu and Yi Susu to come over, Lu Ji pointed to the octagonal well and said, "Look, this octagonal well doesn't look like an acquired gossip map. ”

Gongsun Yu and Yi Susu immediately understood that the acquired gossip map drawn on the Tibetan scripture map was this octagonal well.

Lu Ji continued: "Actually, when I first came to the hospital, I noticed this octagonal well, and at that time I also asked Ci Qian if the image was not like the acquired gossip map, and Ci Qian also said that it is estimated that the previous master liked to study the gossip formation, and it turned out that the mystery was here." ”

"Then the ninth day of the first month, what does it mean that the hidden dragon should not be used?"

Yi Susu is still a little puzzled, although it is said that the gossip map has been found, but what does this sentence represent?

Lu Ji seemed to have a plan in his heart, and pointed to the octagonal well: "You see, this octagonal well is made of rope bricks, and the lower part of the well circle is very regular. ”

Gongsun Yu and Yi Susu still didn't quite understand what Lu Ji said, and they couldn't see it when they stared at the octagonal well, so Lu Ji turned the gossip diagram on the scripture map to the same direction as the octagonal well and said: "Come and see, just take this direction, compare it, is it like the pole gossip map." ”

Finally understood, Gongsun Yu and Yi Susu looked very excited, and Yi Susu hurriedly asked, "Sir, which direction is the ninth day of the first month?" ”

Lu Ji smiled and said: "This gossip of the day after tomorrow was created by Xibohou Jichang when he was imprisoned by King Shang and studied Fuxi gossip in prison, and according to Fuxi gossip; On the ninth day of the first month, the hidden dragon should not be used to be the first line of the Qiangua, the Qiangua is in the northwest direction in the gossip of the day after tomorrow, you look at the northwest corner of the octagonal well, whether the rope bricks are all built into six bars, counting from top to bottom, the sixth bar is the ninth day of the first month.

Yi Susu still couldn't figure it out, so he continued to ask: "What does the sixth bar in the northwest direction mean?" ”

At this time, Gongsun Yu finally understood, only to see him pat his forehead and say, "I understand, this rope brick should be a mechanism, let's find a wooden stick and try it." ”

Just as he wanted to look for it, Lu Ji had already walked over to the well with a wooden stick in his hand, and poked the Jomon brick at the ninth position of the brick wall in the northwest of the octagonal well. Lu Ji felt that this brick seemed to have signs of loosening, so he poked it hard, and then a miracle appeared, this piece of the first nine Jomon bricks was violently poked by Lu Ji, and it turned around, and it was concave on the one hand, and it was convex on the other, as if there was a shaft in the middle of the brick, and at the same time, the brick wall that was about five feet high under the Jomon brick was also slightly concave, and Lu Ji pushed the slightly concave brick wall with a wooden stick, and then saw that the brick wall opened inward like a door, revealing a hole about five feet high and two feet wide.

It turns out that the sentence prompted by the Tibetan scripture map: the ninth day of the first month, the hidden dragon should not be used, in fact, it is hinting at the location of the mechanism to open the cave door, this brick should be able to rotate with a push before, and at the same time, the cave door is wide open, it is estimated that no one has used it for many years, so it has to be so strong just now to open it.

After discovering the entrance to the cave, everyone was excited, but how to get in? Isn't the structure complex inside? Lu Ji had lived in Beibi Mountain before, and often went into caves to explore, but Gongsun Yu and Yi Susu had no experience in this area. I saw Lu Ji bring a wooden ladder, put one end into the hole, and the other end leaned against the edge of the well, holding a torch lit in his hand, and climbed down the ladder to the mouth of the cave.

Lu Ji squatted at the entrance of the cave with a torch in his hand, and saw a secret passage that was sloping downward, so Lu Ji beckoned Gongsun Yu to go in and see, and told Yi Susu to wait outside.

Gongsun Yu also picked up the torch and climbed in along the ladder with Lu Ji. The secret passage slowly leans down, but the slope is not large, at first they have to walk with their waists, but the more they walk, the more they feel that the height of the secret passage is higher, and they are about three zhang away, but they feel that the secret passage is much wider, and the height is also as high as one person, and the secret passage has become flat and does not need to go down again.

There is a wooden ladder here, and Gongsun Yu thought to himself that it was estimated that when the master Yi Wuji escaped from Chang'an City overnight with Yi Susu in his arms, he went down the secret passage and stayed here. They continued to walk four or five zhang away, there was a door in front of the secret passage closed, Lu Ji was busy pushing hard, a miracle happened, the door could actually be opened, so the two of them each held a torch and walked in, but felt that the inside was cheerful, Lu Ji and Gongsun Yu were busy holding the torch and shining around, but saw that it was a secret room, the secret room was square, and the length and width were about more than zhang.

The secret room was full of rolls of bamboo slips, densely piled up on the four walls, Gongsun Yu estimated that there were about three or four hundred rolls of bamboo slips. In the center of the chamber was a table with a brass lamp on it, and the oil in the lamp had dried up, and it was evident that no one had been here for a long time.

Is this the legendary "Bian Que Medical Sutra"?

Gongsun Yu took out a roll in the pile of bamboo slips on the south wall and opened it to see, only to see that there were some diagnosis materials written on it, which was probably Canggong's medical register, and then opened a roll in the pile of bamboo slips on the north wall, only to see that it was written:

The six verses of Tibetan Elephant Theory, the festival of sixty-six, to become one year old, people to ninety-nine system, counting people also have three hundred and sixty-five sections, thought to be heaven and earth. The festival of sixty-six, the ninety-nine system, so the degree of the sky, the number of qi. Those who are in the sky, so they make the sun and the moon, and those who count the qi, so they are also used for the purpose of Ji Huasheng. The sky is yang, and the earth is yin; The sun is yang and the moon is yin; There is discipline in the line, and there is reason for Zhou. There is one degree in the day, and thirteen degrees in the month. Therefore, the three hundred and sixty-fifth days of the month are old, and the surplus is surplus. The end is at the beginning, the table is in the middle, the rest is at the end, and the day is over......

After reading it, Gongsun Yu used his modern memory and thinking, desperately thinking about where this "Six Sections of Tibetan Elephant Theory" came from? Like I have seen it before, you must know that it is estimated that it is in contact with ancient things, and his current mind has less and less modern memory and thinking, and finally came up with it for him after racking his brain, it turned out that this "Six Sections of Tibetan Elephant Theory" is from the "Yellow Emperor's Neijing" of "Su Wen", but the "Six Sections of Tibetan Elephant Theory" in "Su Wen" can have the Yellow Emperor asked, Qi Bo answered, a question and an answer formed, and this bamboo slip was written on it not.

Gongsun Yu opened another volume, and it was written: The envoy of the twelve viscera, the heart, the official of the monarch, and the gods. The lungs, the officials of the prime minister, govern the festival. The liver, the officer of the general, is out of the way. The brave one, the righteous official, decides to come out. Those who are in the middle, the ministers and officials, are happy. Those with a spleen and stomach, the official of Cangli, have five flavors. The one with the big intestine, the preacher of the word, changes out of the way. Those with small intestines, the officials who are sheng, turn into things. The kidneys are strong officials, and they are skillful. The three cokes, the officials who decide to blaspheme, and the waterways are out of the way. The bladder, the official of the state capital, the liquid is hidden, and the gasification can be released. Those who have these twelve officials shall not lose each other.

This volume of Gongsun Yu doesn't need to think about it to know that it is also from "Su Wen", the original name is "Linglan Secret Classics", so I memorized it when I was in college, so I still remember it.

At this time, I heard Lu Ji shouting: "Brother, come and see, there is a secret passage here." ”

Gongsun Yu looked in the direction pointed by the lander, and there was originally a door in the northwest corner, and the door panel was also made of bricks, but it could be pushed open by pushing hard, revealing a secret passage.
