Huang Yongjue and the nine-tailed fox were both looking at Tang Ding, watching how he opened the stone door.

Tang Ding has been looking for this stone gate for a while, but he still hasn't found any mechanism in front of the stone door.

Like this kind of tomb stone door, Tang Ding encountered several, all of which were organs in front of the stone gate, existing in the form of nine palace gossip, with the help of the gravity of the human body, the order of the nine stars flying and falling, in order to open the mechanism.

However, Tang Ding had already rubbed the ground in front of the stone gate with his feet, and he didn't find that there was a Qimen Dunjia similar to the gossip of the Nine Palaces.

However, if this is really where the Nine Heavens Xuannu Tomb is located, then with her achievements in Feng Shui and Qimen, she should put these things here.

When a person is in life, there is something he is very proud of, and he must want to bring this skill into the tomb, whether it is as a show off, whether it is nostalgia for his life or not, in short, he will make such an arrangement in the final analysis.

But where is the mechanism of this stone gate?

Tang Ding walked around the stone gate twice, touched the stone door with his hand, and felt the unevenness of the palm, and the palm-sized place was square, which seemed to be a large seal.

Tang Ding tried to sweep away the dust on it, but found that the dust had condensed on it.

This is due to the continuous evaporation and vapor of the limestone in the boiling water river below, and finally the water vapor and dust cover the concave and convex together, and over time, the original obvious concave and convex because the water droplets are easy to stay in the depression place, and the dust is mixed with the water droplets, and for thousands of years, the original uneven seal has been gradually filled.

Tang Ding used the dragon descending magic sword with him to clean up the unevenness that was condensed on the seal.

Tang Ding's use of the Dragon Descending Sword had already reached the realm of doing whatever he wanted, sending and receiving from his heart, cleaning the dust on this seal, and not touching any part of the seal.

However, after cleaning it out, Tang Ding found that the seal did not seem to be a seal, but like a small combination lock.

Tang Ding looked carefully and determined that this was definitely not a seal, and it looked like it should be carved with the nine-square grid of the nine palaces.

However, this nine-square grid is not the popular Qiangong, Kan Palace, Gen Palace, Zhen Palace, Middle Palace, Xun Palace, Ligong, Kun Palace, and Dui Palace, but an ancient nine-palace grid.

The ancient nine palaces are the main palace, the middle Lu Palace, the South Lu Palace, the Xianlu Palace, the Huang Zhong Palace, the large face tone, the double tone, the Shang tone, and the Yue tone.

The Nine Palaces represent the earth in Qimen Dunjia, the earth, is the foundation of Qimen Dunjia, is immovable, Qimen Dunjia is divided into heaven, earth, people, gods four plates, only the land is immovable, for the mountain.

Although the ancient Nine Palaces and the modern Nine Palaces are different in reading and writing, they are very similar in meaning.

Because the ancient nine palaces are not engraved with words, but the representative symbols of the nine palaces, which do not look exactly the same as the modern popular nine palace symbols such as heaven and earth Lei Ze, but are somewhat similar to modern seals, and can still be identified if you carefully identify them.

This is also the reason why Tang Ding almost admitted his mistake at the beginning.

With just one glance, Tang Ding was able to confirm that this Nine Palace Bagua was not as simple as a pattern, but a modern combination lock. However, this combination lock is a palm-sized mechanism integrated with the gossip of the Nine Palaces, which looks exquisite, but shocking.

The combination lock is only modern and seems simple, but the technology is extremely complex, involving logic circuits, language programming, chip control, digital decoding and other technologies, of course, these technologies are not a secret in modern times, but in ancient times this is equivalent to an Apollo program to the moon, the difficulty can be imagined.

Tang Ding didn't touch the combination lock easily, but was thinking about how to open the combination lock.

Regarding the Qimen Dunjia of the Nine Palaces Gossip, there are many people who have studied it throughout the ages.

Xu Yue of the Han Dynasty "Records of Mathematics": "Nine palaces, five element parameters, like a cycle. ”

Zhen Luan of the Northern Zhou Dynasty said: "The nine palaces, that is, two or four are the shoulders, six or eight are the feet, the left three are the right seven, the nine shoes are one, and the five are in the center." ”

Moreover, the Nine Palaces method is very changeable in its application, and it can evolve hundreds of changes. In ancient times, there were "Nine Palaces", "Nine Palaces", "Nine Palaces", "Nine Palaces", "Nine Palaces and Eight Winds", "Taixia Xing Nine Palaces", "Taiyi Altar", etc., which were widely used in many aspects such as occupation, art, arithmetic, medicine, weft, and construction.

Because there are too many evolutions in the Nine Palaces, this is quite difficult to crack.

Moreover, the Nine Heavens Xuannu is known as the originator of Feng Shui, the heavenly opportunity of the sun and the moon, the changes of the poor heaven and the earth, the vertical and horizontal thoughts, and the elusiveness of ordinary people.

There are too many changes in these nine palace gossip, and if you want to find a correct one from these changes, the probability is low. And Tang Ding wasn't sure if he would never be able to open this door once he missolved the Nine Palaces gossip, or would it release some dark arrows?

Either way, Tang Ding couldn't bear it. If this door can't be opened, Tang Ding will not have a chance to obtain the Nine Heavens Xuannu Feng Shui diagram, which means that he will probably never be able to find the news of his parents again, no matter which one it is, it will be a big loss for Tang Ding.

Therefore, Tang Ding must succeed in one fell swoop.

However, Tang Ding believes that there must be a solution to the "combination lock" made by the Nine Heavens Xuannu.

If this combination lock is not solved, how good it is to block the door directly, why bother to leave this combination lock? Since the Nine Heavens Xuannu left this combination lock, it means that this lock can be unlocked.

But how to unlock this combination lock, Tang Ding didn't think of a way.

It stands to reason that there are two most commonly used gossip in the nine palaces, one is that the middle star enters the middle palace, and the other is that the head star enters the middle palace, no matter which star enters the middle palace, this solution is completely different.

But which star will the Nine Heavens Xuannu let enter the Middle Palace? Tang Ding felt that it was possible.

If the Nine Heavens Xuannu is the originator of Feng Shui, then she can be said to be the first person in Feng Shui, this is the head star entering the middle palace.

If it is said that the Nine Heavens Xuannu is the fifth person ranked outside the Four Divine Beasts under the West Queen Mother's seat, it is the middle star entering the middle palace.

But then again, ranking fifth is not a glorious thing, and with the huge fame of the Nine Heavens Xuannu, it is unlikely that this method will be adopted. If the Nine Heavens Xuannu is the first person in Feng Shui, and the head star enters the middle palace, this seems too far-fetched, who knows if there will be a more powerful person than the Nine Heavens Xuannu in the future?

By the way, there is the number nine in the Nine Heavens Xuannu, this nine characters are very good, it is not only the name of the Nine Heavens Xuannu, but also nine is the extreme number, which not only conforms to her name, but also fits her proud character.

Therefore, Tang Ding was almost certain that the solution to this combination lock must be the Nine Stars Entering the Middle Palace.

Nine stars into the middle palace, that is, nine for the middle palace, one in the dry position, two in the exchange position, three in the Gen position, four in the departure position, five in the Kan position, six in the Kun position, seven in the earthquake position, eight in the Xun position.

Tang Ding pressed the password lock in turn in the order of Zhong, Qian, Dui, Gen, Li, Kan, Kun, Zhen, and Xun, and almost at the moment when he finished pressing, Tang Ding heard a faint sound of the machine, and then the stone door rumbled open.
