In fact, to be honest, this mechanism is a very simple mechanism.

The rock wall in this niche is actually a thick stone slab, which is raised by fine sand below. The base of the stele is the key hub to control the fall of fine sand. As long as the base of the stele is lifted up, the fine sand below the slab will pass through the passage below the base and eventually fall into a hole further below.

Because the rock wall stone slabs have no support from fine sand, they will slowly descend, and eventually reveal the cave behind the stone slabs.

As the stone slabs slowly landed, bubbles of large and small continued to gush out of the holes and rolled towards the top of the head. This phenomenon made Yang Jin a little happy. The fact that so many bubbles appeared meant that the cave behind the stone slab was most likely not allowed to flood water due to air pressure.

Sure enough, after five or six minutes, the stone slab, which was more than two meters high and one and a half meters wide, completely fell down, a dark hole appeared in Yang Jing's sight. Not long after Yang Jing swam in slowly, he saw that the hole that had been facing the slanted upwards had not much water. The water only spread about two or three meters away from the entrance and then stopped abruptly.

This phenomenon directly shows that the cave behind the stone slab is a breathable cave, so that the strong air pressure can be maintained and the water pressing the reservoir cannot enter the cave.

Because of the energy to protect the body, Yang Jin didn't have to worry about the occurrence of decompression disease, and he didn't need to decompression to walk directly into the cave in a diving suit.

However, since it was confirmed that this cave was an impenetrable cave, Yang Jing did not dare to pull out his mask and trachea. Anyway, the high-pressure air in the compressed air bottle can support himself to breathe for a long time. Even if it is not enough, there are two compressed air bottles filled with air in the storage space.

Sitting on the ground, he pulled down the flippers on his feet, threw them into the space, and then took out a pair of shoes from the space to change them. Then he turned on the diving light and continued walking along the passage.

This passage is an upward passage that is nearly forty degrees, with a height of more than two meters and a width of more than one and a half meters. Judging from the cave rock walls, this cave is naturally formed and not artificially dug. Obviously, more than a thousand years ago, Yuechengzi probably discovered this natural cave and thought it was very good, so he built a Taoist temple here.

Facts have proved that Yue Chengzi has a good vision. At least after Yang Jing entered this cave, he couldn't help but sigh at the wonders of nature.

The naturally formed cave is getting wider and wider as it goes inside. After Yang Jing thought that it was more than fifty meters away, he finally arrived at a cave hall with a radius of more than ten meters.

Before, when looking for the treasure of the last Tsar, Yang Jing had encountered a hall larger than this hall, so Yang Jing did not feel so surprised. It was just that in this hall, Yang Jing discovered a very special existence.

It was a stone tablet, two meters high and more than one meter wide. The stone tablet was carved with some strange fonts.

Yang Jing just had a vague impression of this font, and seemed to have seen it somewhere. But what Yang Jing could be sure of is that these fonts are definitely not ancient characters such as oracle bone inscriptions, large seal scripts, small seal scripts, and fonts such as running scripts and regular scripts, but a very rare font.

Looking at the dense and strange fonts carved on the stone tablet, Yang Jing thought for a long time before he suddenly realized that this font was not a Chinese character in the usual sense, but an extremely rare and mysterious aquatic text.

It is actually more appropriate to use another title to call these mysterious words on this stone tablet, that is, "scattered text".

This extremely mysterious vanishing text, also known as water books, also known as ghost books, and anti-books, is a legendary text written for dead people to read.

Shui Book is an ancient cultural symbol used by ancient Shui people, similar to oracle bone inscriptions and bronze inscriptions, recording ancient Aquarium astronomy, geography, folk customs, religion, ethics, philosophy, aesthetics, law, anthropology, etc.

Experts and scholars believe that "Shui Book" is equivalent to the "Book of Changes" of the Han people. It has profound content and is an encyclopedia of the Shui people and an important part of the cultural treasure house of the Chinese nation. In March 2002, Water Book was included in the first batch of "Chinese Archives and Documents List".

The reason why this kind of text is also called "Zhengwen" or "Ghost Book" is that it refers to its font structure. Although some characters are imitating Chinese characters, they are basically written in reverse, writing in reverse or changing the writing style of Chinese characters. Why is the characters "Shuishu" different from Chinese characters? Their writing is opposite to Chinese characters. These questions make people puzzled by the world.

The second reason is that in ancient times, the ancestors of the Shui people were persecuted by the ruling class. According to legend, their ancestor "Lu Duogong" created "ghost books" to oppose and retaliate against the rulers.

Later, Taoism learned from others' strengths and adopted some texts from Shui Book. In combination with the methods used by the "ghost masters" of the Shui Book, some systematic divisions were made. Some of the texts of Shui Book were taken out separately to form the current "scattered text", which is a text specifically written for dead people to read.

Among the geography techniques in the third inheritance skill set that Yang Jing obtained some time ago, there was a special geography. Since Yang Jing obtained geography, he naturally learned how to identify geography. However, Yang Jing has never seen geography in reality, so he just felt that this kind of geography is familiar, but he couldn't remember where he saw it.

Now that she recognized the sacred text carved on the stone tablet, Yang Jing immediately began to recognize these texts.

"In the first year of Tianyou, I went to Shangqing Temple on Wangwu Mountain and traveled around the world. At that time, the world was in chaos and turmoil. In the third year of Tiancheng, I accidentally discovered this cave and was amazed at its magical skills. So I built Yuecheng Temple outside and lived in seclusion here. In the fourth year of Tongguang, I met Li Congke, the commander of the Tang Puqiu City Commander..."

Obviously, the words engraved on the front of this stone tablet are some of the early experiences of Yue Chengzi.

In the first year of Tianyou, it should be 904 AD, which was the last year used by Emperor Zhaozong of Tang Dynasty. As for the third year of Tiancheng, it refers to the year name of Li Cunxu, the founding emperor of the Later Tang Dynasty. This year should be 910 AD. In the fourth year of Tongguang, it was the last year used by Li Cunxu, and it was also the last year of Li Cunxu's reign.

Yang Jing also understood the meaning of this sentence very well. In fact, Yuechengzi himself told that he started his master from Shangqing Temple in Wangwu Mountain in 904 AD, and then began to travel around the world. Then he discovered this cave here in 911 AD, and felt the turmoil and chaos in the outside world, so he built Yuecheng Temple here and lived in seclusion here, and then met Li Congke in 926 AD.

Because it involves the imperial seal, Yang Jing was not idle while waiting for diving equipment in Luoyang, but carefully read the history of that period, so he is still very familiar with the history of this period.

During that period, the Tang Dynasty lost the world, and the heroes emerged, and the world collapsed. The whole of China was ruined.

Li Congke was the adopted son of Li Siyuan, the second emperor of the Later Tang Dynasty. In the third year of Tongguang, that is, in 925 AD, Li Siyuan was ordered to go north to resist the Khitan. Because his family was in Taiyuan, Li Siyuan submitted a petition to appoint Li Congke as the commander of the Yanjing Inner Court. Zhuangzong was unhappy and appointed Li Congke as the commander of the Tuqi Metropolitan Commander and stationed in Shimen.

The following year, the Weizhou army rebelled and Li Siyuan rushed to Luoyang. At that time, Li Congke led his subordinates from Quyang and Yunxian to Changshan in Hengshui, met with Wang Jianshe, and crossed the Yellow River to march southward. Therefore, Li Siyuan's army was in great force.

Li Congke's experience coincides with what Yue Chengzi said. It is estimated that Li Congke, who was the commander of the Tuqi Capital, met Yue Chengzi when he went south to cross the Yellow River in 926.

In the same year, Li Siyuan ascended the throne and became the second emperor of the Later Tang Dynasty, and even appointed Li Congke as the governor of Hezhong. Yuechengzi's Yuecheng Temple happened to be within the jurisdiction of Li Congke. In other words, when Yuechengzi met Li Congke eight years before Li Congke became the last emperor of the Later Tang Dynasty.

In this way, Yang Jing even figured out the relationship between Yue Chengzi and Li Congke.

"......... In the first year of Qingtai, I was invited by my emperor to join Luojing as the official of Taizhong of Sitian. In the third year of Qingtai, the traitor Shi Jingtang raised an army, but Luojing was in danger day and night. In the face of danger, the emperor ordered me to meet and ask for a plan to withdraw the army. However, how could I pacify the world just a Taoist, how could I pacify the world? The emperor became increasingly anxious. In the intercalary November, Shi Jingtang's army was at the city of Luojing. The emperor wanted to do something to self-destruction, but he was unable to persuade him.

When the emperor brought the imperial seal and the empress dowager, the empress, and the prince climbed the Xuanwu Tower, he gave all the ministers poisoned wine, and I was also listed. Fortunately, I had been practicing medicine for many years and was prepared. I did not die immediately after drinking the poisoned wine, so I saw that my emperor was burning himself.

When the fire was extinguished, I took the imperial seal from the fire, quietly left the palace, and returned to the Taoist temple. However, the poisonous wine was very toxic and the remaining poison was not clear. I knew that my life would not last long, so I built a mechanism outside the cave to close the cave.

The inner cave has a seal of the imperial seal and the gifts given by our emperor over the years. It is blocked by stone gates and protected by organic traps. I erected this monument with the sacrificial text. If my descendants want to enter the inner cave, they must first obtain the inheritance of my Tao before they can know how to enter the cave. If you forcefully break into the inner cave, you must be buried here!

When you meet three left one, six left one, two left one side, nine progress one side, one cross the trap. Five steps one down, nine steps one jump and one squat, thirteen steps one right two feet, one finish in one go, passing the flying blade. Four left four press, eight right lift, twelve forward, three feet forward, and three feet forward, and one rolling stone. Four front four back one, two left front three, three back one right three, five front one first one first seven, and one cross the arrow. Qian pushes Zhen lift, Gen right turn Kan turn left to break the dragon stone. "

The stone tablet ended here, but Yang Jing was thrilling to see it.

He really didn't expect that Yue Chengzi's scheming was so insidious. There was no doubt that the imperial seal fell into the hands of Yue Chengzi, but Yang Jing really didn't expect that Yue Chengzi had set up so many mechanisms in this cave in order to protect the imperial seal!
