This cave hall is deeply sunken, the top of the hall is level with the position where Yang Jing is standing now, but the bottom of the hall is seven or eight meters deep at the feet.

Obviously, from the location and depth, it is clear that this cave hall is the heart of the entire cave. This cave hall and the four sections of the cave outside together form a "Hui" shaped structure, and the four sections of the cave full of traps outside are the outer circle of the word "Hui", and this cave hall is the small "mouth" inside the word "Hui".

Yang Jing approached the rock wall at the entrance of this cave hall, looked at it for a while, and then reached out and touched the rock wall, then shook his head in surprise.

If I'm not mistaken, this cave hall was actually carved out of the mountain!

In other words, if the four sections of the cave outside were the product of natural formation and slightly artificial modification, then it is very likely that this cave hall was completely hard-hewn out of the mountain!

By this time, Yang Jing was almost convinced that there was no doubt that this cave was not built by Yuechengzi at all. He just found the place and took it for himself.

It's just that such a huge project, what did that bull fork figure do?

Combined with what he had guessed in the cave hall outside, Yang Jing estimated that this cave was most likely built by an emperor of the Tang Dynasty!

The ancient emperors of China often began to prepare for their posthumous affairs as soon as they ascended the throne, accompanied by the enthronement of a generation of emperors, and on the other hand, the construction of the vast imperial tombs.

And an imperial mausoleum often takes years or even decades to build. There are many short-lived emperors who began to build their own mausoleums after ascending the throne, but most of the mausoleums could not be repaired until they died......

If this cave was really an imperial mausoleum, with the level of construction at that time, it would have taken at least ten years to build this mausoleum!

With a slight breath, Yang Jing slowly stepped on the steps that extended down from the entrance and walked to the bottom of this cave hall.

The staircase was clinging to the rock wall on one side, and when I went down and took out the battery lights, the bottom that had been looking a little blurry on the top was all lit up all at once.

The length and width of the entire hall are more than ten meters, which is about the same size as the first cave hall. In the very center of the bottom of the hall, there is a raised square stone platform, next to the stone platform there is a stone tablet more than one meter high, and on the stone platform a completely decayed skeleton sits there, between the two thigh bones of this skeleton, there is a jade box less than a foot in circumference......

This jade box should have been held in the lower abdomen before the skeleton was alive, but when the flesh decomposed, this jade box naturally fell between the legs.

A complete skeleton holding a jade box in its hand, what does this mean?

It goes without saying that this jade box is absolutely of extraordinary significance to this skeleton.

This situation made Yang Jing extremely excited, and the scene in front of him obviously showed one thing, that is, the thing contained in the jade box was very likely to be the heirloom jade seal!

Yang Jingqiang suppressed the excitement in his heart, and walked quickly to the skeleton, only to find that this skeleton was not only holding this jade box, but also had some other things in the skeleton.

On the stone platform on the back of the bones, a hosta fell, and one end of the hosta was carved with Taiji Yin and Yang fish, which was obviously not a hairpin used by ordinary women, but a hairpin worn by a Taoist priest.

In addition to this hosta, there is also a dusty jade handle on the arm bones of this skeleton, and the beast hair on the dust has long since rotted without a trace, leaving only such a dusty handle. Since the dusting handle is also made of jade, the handle is not rotten.

At the left arm bone of the skeleton, there is also a yin and yang ring made of jade.

Obviously, what remains of this remains is an indication of the identity of this skeleton - this skeleton was a Taoist priest during his lifetime.

Because whether it is a hosta with a yin and yang fish carving, or a dust whisk without animal hair, or a yin and yang ring with two rings together, they are all ornaments worn by Taoist priests.

In other words, the identity of this skeleton before its death can already be called out - Yue Chengzi.

If this skeleton was really Yuechengzi before his death, then the jade box between the bones and hands must contain the legendary heirloom jade seal.

Although Yang Jing was very excited, he was not in a hurry to get the jade box, but after stabilizing his mind, he carefully looked at the stone tablet next to the stone platform.

This stele is the same as the stele outside, it is carved in the inscription, Yang Jing recognized it for a long time, and then translated the content carved on this stele.

These contents surprised Yang Jing.

The stele is roughly like this.

In the first year of Tianyou, that is, in 904 A.D., Yuechengzi traveled the world after leaving the Shangqing Temple of Wangwu Mountain, and inadvertently got a secret volume, knowing the general location of a mausoleum built by Wu Zetian, the emperor of Wu Zhou more than 200 years ago, so he took six years to find this mausoleum suspected to be built by Wu Zetian, the empress of Wu Zhou, in the third year of Tiancheng, that is, in 910 years in the park.

This time point is consistent with the time mentioned on the previous stele, but the previous stele is not so detailed, and this stele is detailed how Yue Chengzi discovered this Wu Zetian mausoleum.

Seeing this, Yang Jing smiled. This cave is indeed an imperial mausoleum of the Tang Dynasty, and it is also the mausoleum built by the legendary Wu Zetian for himself.

After all, Wu Zetian took the world of the Li family and set up the capital in Luoyang, which is obviously Wu Zetian had a ghost or a shame in his heart at that time. Since Wu Zhou even changed the capital, it is very likely that Wu Zetian did not want to be buried with Li Zhi after he died after he ascended the throne and became the empress, so he built his own mausoleum under Daimei Mountain.

But in the end, this mausoleum Wu Zetian was not used. Although the empress was seriously ill, the dragon changed, and Wu Zetian returned the imperial power to the Li family, but Li Xian, that is, Tang Zhongzong, was Wu Zetian's third son after all, so after Li Xian ascended the throne, after the death of his mother Wu Zetian, Wu Zetian and his father Li Zhi were directly buried together.

After Wu Zetian's death, he was buried by his son in Qianling, and he was buried with his husband Li Zhi, so this mausoleum naturally has no use.

According to the scale of this mausoleum, it is not that a female emperor like Wu Zetian can have the ability to build such a powerful mausoleum, and I am afraid that another person will not have such financial resources. Of course, the emperors of the Tang Dynasty after Wu Zetian had the ability and financial resources to build such a mausoleum, but the mausoleums of the Li family were all built in the Eighteen Tombs of the Tang Dynasty, and it was impossible for these emperors to build a mausoleum under Daimei Mountain without letting go of the ancestral tombs.

In this way, Wu Zetian didn't know how much manpower and material resources were spent to build this mausoleum, but in the end he didn't use it, but it was cheaper to Yuechengzi.

The next thing that the inscription says is how Yue Chengzi got acquainted with Li Congke, how he was valued by Li Congke, and how he was summoned by Li Congke to Beijing after Li Congke ascended the throne and became the late emperor of the Later Tang Dynasty.

It focuses on the process of how to get the national seal.

After Yue Chengzi drank the wine given by Li Congke, because he secretly took the antidote he configured, he was not poisoned on the spot, but saw Li Congke with his wife, children and old mother, sitting on the Xuanwu Tower with the jade seal of the country in his hand, and then ordered the guards of the forbidden army to set fire to the Xuanwu Tower.

Because Li Congke threw himself into the fire, the entire Luoyang Palace was in chaos, and the palace maids and eunuchs in the palace took advantage of the chaos to loot many treasures and escaped, but no one came to Xuanwu Tower because of the fire.

After the fire was extinguished, Yuechengzi secretly found the jade seal that had not been burned, and then quietly slipped out of Luoyang Palace and returned to Yuechengguan. However, because the residual poison has not been cleared, Yue Chengzi has not been known for a long time, and finally moved all the precious things rewarded by Li Congke during the Zhongguan Zheng period of the Tiantai Dangsi into this Wu Zetian mausoleum, and then left a stone tablet in the cave hall outside, and restarted these organs, and finally came here alone, after carving this stone tablet, holding the jade seal of the country and waiting for the arrival of death.

There is no doubt that this skeleton was left by Yue Chengzi, and the jade box contained the heirloom jade seal that had been missing for more than a thousand years.

However, in the inscription, Yue Chengzi also mentions some other things, such as if there is a junior who comes here, please dispose of his remains properly. There is also a very important information that Yue Chengzi knew that this mausoleum full of organs was a mausoleum prepared by Wu Zetian for himself, but he did not completely explore this tomb, and he did not enter the main tomb. The rewards he had received from Li Congke were placed in a burial chamber with him.

Seeing this, Yang Jing couldn't help but sigh.

This Yue Chengzi is also a generation of heroes, and he thought that such a sinister trap was arranged by him, but now it seems that he guessed wrong. These traps were all set by the empress Wu Zetian.

But it's no wonder when you think about it. Although Wu Zetian was domineering, she single-handedly established the Wu Zhou Dynasty and became the only empress in Chinese history, but she was a woman after all, and she was married to the Li family. So after she won the world, there must be a ghost in her heart.

Perhaps it was because there was a ghost in his heart that Wu Zetian was worried about this and that when he built his mausoleum, he was worried about this, so he built his mausoleum with a lot of mechanisms......

Yuechengzi is just a magpie's nest.

However, Yue Chengzi was able to insist on hiding the jade seal of the country after drinking the poisonous wine, no matter in any way, he was credited to Huaxia. If it weren't for him, no one could tell what would happen to the jade seal of the country. But with Yuechengzi, although the jade seal of the country has been missing for thousands of years, it finally returned to the hands of the Chinese people!
