The diameter of this Bagua diagram is more than one meter. It is a standard Bagua diagram of King Wen of Zhou, not the legendary Fuxi innate Bagua diagram.

Fuxi's innate Eight Trigrams diagram is that Gan Tian is above, Kun is below, Li Fire is on the left, Kan Water is on the right, and other Dui, Xun, Gen, and Zhen are arranged in four corners, forming the innate Eight Trigrams diagram.

King Wen of Zhou later thought about Fuxi's innate Bagua diagram and created the acquired Bagua diagram, which is the type of Bagua diagram we often see later.

The innate Bagua talks about confrontation, that is, the eight types of objects represented by the Bagua are divided into four groups to illustrate the relationship between yin and yang. The acquired Bagua talks about popularity and cycle cycles, such as water flow, to indicate the dependence and mutual roots of yin and yang, and the mother-son coexistence of the five elements.

Therefore, the innate Bagua diagram and the acquired Bagua diagram are very different.

The Bagua diagram of the acquired Bagua is that Li fire is on the top, Kan water is on the bottom, Zhen thunder is on the left, Dui Ze is on the right, Gan Tian is on the bottom, Kun is on the top, Xun wind is on the top, Gen Mountain is on the bottom, and Separate from the four corners.

According to the carved by Yuechengzi on the stone tablet, if you want to open the Dragon Breaking Stone, you must control the Bagua diagram in the order of "Tan Push Zhen Li, Gen and right turn Kan and left turn".

Yang Jing stood in front of the Bagua Diagram, carefully observed the Bagua Diagram for a while, and finally figured out what the Bagua Diagram mechanism was.

On this Bagua diagram, there is a square stone strip about ten centimeters square on the inside of each hexagram position. All of these eight stone strips are inserted into the rock wall, revealing the rock wall about five centimeters. Obviously, these stone strips should be the key to controlling this Bagua diagram.

According to the tips on the stone tablet, these stone strips should be movable. The stone strips penetrate deep into one end of the rock wall and are connected to different mechanisms. If you follow the tips of Yuechengzi to control these stone strips, the final result will be opened to lock the broken dragon stone, and finally remove the broken dragon stone weighing more than ten tons completely.

But similarly, if the operation is wrong, the outcome is very likely to cause another mechanism to attack and lock the Dragon Broken Stone directly. If you want to open the Dragon Broken Stone again, it is almost impossible.

Yang Jing calmed down and stretched out his hand to push the stone strip at the Gantian position at about 4:30. The stone strip pushed in about 20 centimeters, directly vanishing Yang Jin's palm.

After hearing a clear and audible mechanism inside, Yang Jing felt relieved. Then he grabbed the stone bar at the thunder position at nine o'clock and pulled it out with force, and pulled the stone bar out again twenty centimeters.

After a sound of the mechanism ended, Yang Jing followed the prompts to follow the instructions.

Finally, after all this, a huge "click" sound began, and then Yang Jing saw that the motionless broken dragon stone began to move to the side.

When the Broken Dragon Stone flashed through a gap, Yang Jing faintly heard the sound of water flowing from it. At this time, Yang Jing finally understood what the power source of these mechanisms was.

If you guess correctly, there should be an underground river in the space behind the Broken Dragon Stone. In addition, the annual precipitation in the Daimei Mountain area is relatively abundant, so this river has been maintained. It is estimated that Yue Chengzi had taken a fancy to this river at the beginning, so he used the power provided by the river to create so many mechanisms.

Of course, as for whether this guess is correct, you have to take a closer look after it before you can find out.

When the Broken Dragon Stone dodged about one person wide, Yang Jing finally saw a corner of the Broken Dragon Stone clearly.

This broken dragon stone is larger than previously guessed. Judging from the exposed corner, this broken dragon stone is four meters square and one meter thick, and the distance between the four sides of the rock wall is half a meter. In other words, the weight of this broken dragon stone is much larger than the fifteen tons previously guessed. According to the size of this broken dragon stone, the total weight of this broken dragon stone has exceeded thirty-three tons!

At this time, Yang Jing finally understood that this broken dragon stone should not have been transported from outside, but was directly sourced from the local material and polished with a whole piece of chiseled rock.

This stone probably spent a lot of effort on Yue Chengzi at the beginning.

However, Yang Jing did not think it was so awesome. After all, when the Egyptian Khufu Pyramid was built more than 4,000 years ago, the average weight of each huge stone was 2.5 tons, and the largest stone weighed more than 50 tons. Compared with the Khufu Pyramid, this broken dragon stone was not even a drizzle.

After waiting for about five or six minutes, the huge broken dragon stone finally moved away completely. A square stone door that was three meters wide appeared in front of Yang Jing. However, behind the stone door was still a dark area, and no other sound could be heard except for the clear sound of water flowing.

Yang Jing walked in. Under the light, the first thing that caught his eye was the small waterfall nearly two meters wide.

Yang Jing turned his body and under the light, Yang Jing saw that this was a space similar to the cave hall outside, but the area was much smaller, with a radius of only seven or eight meters.

A waterfall poured down above the rock wall opposite and fell into a pool below. Then the water in the pool flowed along the pool, flowing all the way to the wall at the other end, and hiding deeply into the dark cave.

Yang Jing began to pull out things from the storage space, mainly several battery lamps with strong brightness. This place has been closed for at least a thousand years, and the air has not flowed. Even if the generator is taken out, it may not be fired, so it is best to use a battery lamp.

As these battery lights lit up, the entire cave hall immediately appeared in front of Yue Chengzi.

When Yang Jing saw the gorgeous murals on the four walls of the cave hall, Yang Jing immediately frowned, but the guess in his heart was becoming more and more obvious.

"Is this cave really a tomb before? Otherwise, why did such gorgeous murals appear?" Yang Jing leaned closer to the rock wall and looked at the murals carefully. The more he looked, the more shocked he became.

The content of these murals is rich and colorful. Some are a group of people playing polo and many people are cheering around, some are hunting on horseback or walking, and some are some palace maids with fluttering clothes dancing...

Seeing these murals, Yang Jing could almost confirm that these murals were extremely precious murals of the Tang tomb.

The imperial tombs of the Tang Dynasty had a distinctive feature, that is, they were painted with extremely exquisite murals on the walls of the tombs. Just like the murals of the Tang tombs collected in the Shaanxi Provincial History Museum, they are the only ones in the world.

In the collection of the Shaanxi Provincial History Museum, there are many extremely precious mural treasures such as the pictures of the tomb of Prince Zhanghuai, the polo pictures, the hunting and travel pictures, the tomb of Prince Yide, the ceremonial guard pictures, and the palace maids of Prince Yongtai.

Although Yang Jing has never seen these precious mural treasures in the collection with his own eyes, he has seen them many times online. The murals in the cave hall in front of him are no worse than the mural treasures collected by the Shaanxi Provincial History Museum!

"Is this cave a tomb of the imperial tomb of the Tang Dynasty?" Yang Jing thought, rubbing his chin.

From the overall perspective of this cave, it really looks like an imperial tomb of the Tang Dynasty. Tang tombs, especially imperial tombs, were built into tombs, without tomb doors, and there were a large number of decorations in the tombs. In addition, there were many exquisite murals in the tomb chamber.

This cave is hidden in the mountains, and the entrance of the cave is even hard to find. There are so many exquisite murals. In addition to not seeing the exquisite decorations in the Shinto, this cave is in line with the characteristics of the Emperor's Tomb of the Tang Dynasty.

As for the lack of decorations in the Shinto, it is easy to understand. Perhaps it was because Yue Chengzi changed the Shinto into a mechanism trap after discovering this place? Or maybe it was simply that the person who built this Tang tomb directly converted the Shinto into a mechanism trap.

After all, Yang Jing has deeply felt the danger of these mechanism traps along the way, and is also very clear that to build such a sophisticated and complex mechanism trap, it will take a lot of manpower and material resources. With Yue Chengzi's financial resources, even if he is just a fake public service, he may not be able to complete such a huge project in just three years.

Yang Jing shook his head vigorously, not considering this for the time being, but continued to walk towards the direction of the underground river flowing.

After following the Dark River to walk about ten meters from this cave, a larger cave hall appeared in front of Yang Jing. Judging from the location of this cave hall, this cave hall is obviously located in the center of the character "叶" composed of the four caves just now.

This cave hall is not only large, but also has a deep height, with a downward appearance of seven or eight meters. A complete circle of stone mechanisms that look very complex are surrounded by the rock walls around the hall. Each rock wall mechanism has a sink divided from the underground river. However, where these sinks meet the river, there is a stone slab blocking it, and the water in the river cannot flow into the sink.

Seeing these things, Yang Jing finally breathed a sigh of relief. It seemed that his guess just now was very correct. These sinks were the source of power to those mechanisms.

When a person enters those four caves, as soon as he enters, the corresponding stone slab will rise, and then the water flows into the sink from the underground river, and uses the power of the flowing water to open various mechanisms. When the mechanism is successfully broken, these stone slabs will fall down again, blocking the flow of the water flow, thus causing the mechanism to lose its power and restore it to its original appearance...
