Wang Cheng crawled out of the cave, and he found himself in a room.

The room is not big, the size of a single room, only ten square meters, and the furnishings are simple.

A desk, there is an oil lamp on the desk, the light is white but not dazzling, it burns quietly, and the flame emits a calm fragrance.

"Deep Sea Shark Oil!"

Wang Cheng smelled this familiar smell, and thought that when he first entered the underground royal tomb of the wood country, the everlasting lamp in the royal tomb was also the lamp oil made of the grease of the deep-sea shark people.

This lamp oil is worth 10,000 gold, not only does it not go out for many years, but the aroma released by the burning of lamp oil for a long time can easily make people enter a state of emptiness, which is conducive to cultivation.

There were two bookshelves on either side of the room, but the space on the shelves was not a single book, only some powder.

Wang Cheng also noticed that there was only a pile of powder left on the desk, and there was no book in sight.

"It's all weathered?"

He remembered a documentary he had watched, which was dedicated to the tombs of kings, and once the underground tombs of kings buried for thousands of years were opened, the originally well-preserved books inside would be quickly weathered.

The mausoleum of Zhaogong has survived for nearly a thousand years, and it is difficult to preserve cloth and paper, but it is very likely that the bamboo slips will be preserved intact.

It's just that the gold-eating insect has already opened up this place, and after such a long time, it is even more impossible for Shujian to stay, and even if he stays, who knows if he will be bitten by the gold-eating worm?

"It's a pity!"

Wang Cheng shook his head, the book that can be used as a funeral companion must be precious.

As he stepped out of the room, his vision widened.

It's a space the size of a football field.

It is nearly 200 meters long from east to west and nearly 150 meters wide from north to south, and is rectangular in shape.

The bottom is thirty or forty meters high from the sealed soil, so some buildings were built.

This is the main body and burial chamber of this underground royal tomb, that is, the underground palace!

The light in the dungeon is very good, and there is a huge luminous sphere under the sealed soil, like a small sun, illuminating the entire dungeon as if it were day.

Wang Cheng stood in a long corridor, and there were also "single rooms" on both sides.

Not only on both sides, but also on all sides, there are such rooms on each side.

And one by one, there are as many as nine layers from the bottom to the top, quite like the Longmen Grottoes.

The difference is that the Longmen Grottoes were built on the outside, but here they are built on the inside, and the grandeur of the latter is far above the former.

Wang Cheng himself stood on the sixth floor, looking ahead, and everything in the underground palace was in full view.

The place that catches the eye is the underground dark river, because it is located in the underground palace, this dark river has become a bright river.

The river is still flowing quietly, even after a thousand years, even if it is ten thousand years, it is still the same.

In the direction of the river, there is a mound of earth, but it seems more appropriate to call it a "mountain".

Although it is only a few tens of meters high, it has a roof, a slope, and a foothill, which is connected with the ground of the underground palace.

There were a few plants planted on the hillside, but there were almost no alive, all that was left was a few trunks, and for some unknown reason, all of them died.

The surrounding mist sets off the hill like an overseas fairy mountain.

"This is the Imperial Tomb?"

Before this, Wang Cheng had never seen the true appearance of the underground palace in the emperor's mausoleum, and this was the first time he had seen it, which was really beyond his expectations.

It's not as extravagant as imagined, some are just the vicissitudes of time, the reluctance of a generation of emperors to the mountains and rivers, and some are just the majestic and the guidance of a person in power.

Suddenly, Wang Cheng's eyes focused on the top of the mountain, where a huge coffin was displayed.

"The coffin is on the top of the mountain?"

Wang Cheng was confused, he only hated that he usually read few books, if Yang Si could probably see some doorways by his side, there would definitely be a source for placing the coffin like this.

After thinking about it, he still didn't go to the top of the mountain immediately, but continued to investigate along the corridor.

There were quite a few rooms on the sixth floor, each one furnished like the one he had entered.

A desk, an oil lamp, two bookshelves, and nothing but dust.

"Every single one?"

Wang Cheng walked through the entire corridor on the sixth floor, but he didn't find a complete book, which made him very disappointed.

He jumped down from the sixth floor to the fifth floor, where he entered a room with the same furnishings as the sixth.

Originally, he thought that there was nothing left on the fifth floor, but unexpectedly, there was something preserved in the room he entered.

There are a lot of cloths in the space of the bookshelf, some of which are already in tatters, and some of which are still relatively well preserved.

Wang Cheng took a piece of cloth from the bookshelf and carefully unfolded it, and what caught his eyes were rows of ancient characters, some of which he didn't even recognize.

In fact, he didn't specifically study ancient characters, he was able to know because there were many ancient books in the Martial Arts Pavilion of Ninghou Mansion, and he knew some of them by consulting others and even Mengdai guessing.

"The position of the Great Sima is in charge of the nine laws of the establishment of the state, and the king of the state is in peace. Conquer the country and make the country right; Set up servants to discern their positions, so that they may be ...... by the nations."

Wang Cheng picked a few sentences that he could fully understand, and immediately knew that the content recorded in this silk book was the "Gift of the Great Zhou" that Zhaogong had spent ten years working on.

He summed up the reasons for the outbreak of the "Chengkang Rebellion", and believed that the Zhou people did not know how to be polite when this turmoil occurred, although there were also classes such as ministers, scholars, and doctors, but the division of their rights and responsibilities was not clear.

Zhao Gong thought that it was because these nobles did not understand their duties and interfered in the affairs of the court that caused turmoil, and if everyone performed their duties, such a thing would not have happened.

After reading this volume of silk books, Wang Cheng entered the next room and also found a few relatively well-preserved volumes.

After the entire fifth layer was investigated, he almost knew the content of the silk books included in the fifth layer.

The silk books included in the fifth layer are divided into three categories, one is naturally "The Rite of the Great Zhou", the other is "Statecraft", and the other is "Summoning the Public Living".

A few years before Zhao Gong came to the fiefdom of Wuyuan, King Kang often sent people to ask for his opinions on matters of governing the country.

Over time, he compiled these statecraft into a book. In his old age, these books could not be loaded in several carriages, and finally accompanied him to the royal tomb.

Among these three types of silk books, "Notes on the Summoning of the Public" is the most inconspicuous, but its value is not below the first two.

It is said to record the life of Zhaogong, but in fact, most of the content is his discussion with his disciples, and the content is all-encompassing.

There are astronomy and geography, ancient and modern anecdotes, life thinking, family and country, and more than half of the dozens of rooms on the entire fifth floor are included in these.

Although Wang Cheng is a science student, he is highly educated, and he knows very well that these silk books contain great value, which can be described as the hard work of Zhaogong's life.

"It's a pity!"

He couldn't help but sigh lightly, such a precious thing can only be buried deep in the underground palace now, and it will dissipate with the years, which is regrettable.

Except for "The Gift of the Great Zhou", most of these silk books are solitary, and as a result, many of them have been weathered and can never be reproduced in the world.

On the fourth floor, the tightly arranged rooms are still in the same style as before.

On the bookshelf are stacks of bamboo slips, which are well preserved, but the inscriptions on them are much older, and Wang Cheng basically does not know them.

But thinking that these books can be buried in the Zhaogong Mausoleum, it must be very precious, so I opened the eye of perspective and used the function of not forgetting to "scan" all these words into my mind.

Jumping to the third floor, there are several bronze tripods in the single room, and some more ancient characters are engraved on the walls of the tripods.

Wang Cheng is completely illiterate, and he is very familiar with these words, but he doesn't know any of them.

I turned several rooms in a row, and there were mostly bronze tripods in it, and there were also some fragments of clay pots, which were also engraved with words.

"Jin Wen?"

Wang Cheng remembered the history of the evolution of Chinese characters explained by his Chinese teacher when he was in middle school.

From the oracle bone inscriptions recorded on oracle bones and animal bones, to the gold inscriptions recorded on bronzes, and then to the seal scripts recorded on bamboo slips...... The evolution of writing has also been accompanied by a change in the tools used to record it.

It is not so much the evolution of writing as the evolutionary history of human culture.

After the entire third layer was turned, Wang Cheng had an extra bronze alchemy furnace half a meter high in his hand.

It's not that he doesn't want other things, it's that those tripods and kettles are very heavy, and he can handle them, but it's too difficult to leave with them.

This alchemy furnace was the smallest of all the things in the third layer, and as for those clay pots, they were not in his consideration at all, although they were antiques, they were of little use to him.

However, he wrote down the words engraved on these things.

Second floor.

Bookshelves appeared in those private rooms again, but instead of books, some animal bones and armor were placed on the shelves.

"It's Oracle!"

Wang Cheng thoughtfully, quickly finished the second layer, he picked a few pieces of animal bones and tortoise shells, and came to the first layer.

On the first floor, there are no single rooms, replaced by flat walls with murals painted on the walls.

Standing at the bottom of the floor, he looked up and saw a three-dimensional picture of the entire underground palace in his mind.

Wang Cheng's expression changed drastically, it turned out that the entire underground palace was not boxy, but large at the bottom and narrow at the top, it was actually a pyramid-like structure, and the things placed on each layer had an extraordinary significance.

First floor: murals

The second layer: tortoise shells, animal bones

The third layer: gold inscriptions, pottery shards

Fourth layer: bamboo slips

Fifth layer: cloth

Sixth layer: paper

7th Floor:

8th Floor:

Level 9:

A noun suddenly flashed in Wang Cheng's mind, and he blurted out: "Nine-story Demon Tower?? ”

He was shocked, and all that appeared in his mind was the plot of the movie "Nine-Story Demon Tower", as well as some demons and monsters and other hoodoos.

"Impossible!"

Wang Cheng shook his head, what kind of person is Zhaogong, how can he be involved with these evil things?

Suddenly, he thought of something and immediately looked back at the mural behind him.
