When I walked into the mountain demon, I glanced at the strange stones around me, very much like the rockery in the backyard of the rich family, it was obvious that these stones were not naturally formed, their shape was still different from the karst style of Yunnan, and then I saw that this was a depression, several meters lower than the surrounding number.

I would venture to guess if it could be the crater that was smashed by the huge meteorite that fell back then, and the extremely high temperature burned the surrounding area like this.

Compared with the surrounding raised stones, the huge mountain demon in the center is like a behemoth, looking at it this way, it is as high as a ten-story building, hundreds of meters wide, at this time, there is no grass and trees to set off and cover, the whole is exposed, and the surface layer is actually a layer of patina.

I understand! In the legend told by Antique Lee, the villagers used a meteorite with a very high metal content to create three large bells, which are supposed to be the fragments of this large meteorite.

Later, I learned that this meteorite is called meteorite copper, and its copper content is more than 50 percent, which is hundreds of times that of the earth's natural copper ore. Obviously, the huge meteorite in front of us has a better copper content, and when viewed from such a close distance, it looks like a large copper lump covered with patina.

Li Xiaobai and Zhang Kailong were speechless, such a large meteorite is really rare!

"Little brother, you come with me!" The chief steward whispered and walked to the side.

We didn't have time to think about it, so we hurriedly followed.

After walking half a circle around the meteorite, she stopped in front of a rift.

It's said to be a crack, but it's actually enough to accommodate a fat man in and out.

"That's where they got into the mountain demons—" said the archsteward.

I don't know if the so-called "they" refer to the ancestors of the Jade Girl Village, or the foreign treasure thieves.

The chief steward knows about the existence of this rift, so grandma must also know, maybe there are still a lot of secrets that have not been told to me!

We also walked along the rift.

After walking more than ten meters, there are obvious traces of human activities on both sides of the rift, and someone may have transformed it by the crack, no need to ask, this person is Dayu nine times out of ten.

As you walked, the cracks became tunnels, and the sides and the roof of the cave became very smooth, as if someone had polished them with gauze.

"Look! Is that...... That's a door! Zhang Kailong exclaimed.

Although my eyesight is good, there are too many distractions in my mind at this time, and I keep scanning the sides without paying attention to the front.

Hearing Zhang Kailong's shout, I looked for prestige, and there was indeed a door standing in the distance. It was a huge bronze door, at least three or four meters high and three or four meters wide.

"It's the bronze door again!" Chen Laosan also saw it and exclaimed.

According to Chen Laosan, when he was young, he also saw another equally huge bronze door under the Yellow River, so there are at least three huge bronze doors in the world.

In addition to the same huge bronze doors, these three bronze doors are also out of the Yellow River (this valley was once the Yellow River Ancient Road), not to mention ancient times, even today, if you want to cast such a huge metal door, you have to use a lot of tools, so it can be judged that the people who cast this kind of door have mastered advanced smelting and casting technology.

Could it be Dayu?

Think about it, when Uncle Shi took us into that strange place, the name of Dayu was engraved on the huge banyan tree, and this is the tomb of Dayu......

But if it is Dayu, there is also a contradiction, because the big banyan tree located at the junction of impressions is also engraved with the name of Chiyou. Chi You is a person of the same era as the Yellow Emperor, it can be seen that in his generation, the bronze door already exists, how can it be made by Dayu, who was born hundreds of years later?

In this way, the person who can make the bronze gate is at least no later than the time of the Yellow Emperor - suddenly I thought of two generals, the minister and Pangu.

The general once said that the four of them learned some skills from their masters, Nuwa's ability is probably to create life, which is equivalent to the mother of mankind, and Fu Xi is proficient in divination and gossip, and has also invented a lot of things to use, and the general has never said what he and Pangu have learned.

But recalling the content of the conversation between the two of us, he once mentioned that Nuwa's success in mending the sky was manipulated by him, in other words, the real person who mends the sky is the general, and he also smelted the Xuanyuan sword, which shows that the casting level is extraordinary.

Could it be that these bronze doors were cast by the generals?

Another possibility is Pangu.

There are very few records about Pangu in the history books, and almost all of them appear in the wild history, one of the main reasons is that Pangu hung too early, and after "standing up to the sky", he chose to integrate himself into the earth and became a hero.

What did Pangu learn? Could it be the superb smelting technology? In addition, Pangu was a giant, and in that era, if he wanted to cast such a huge bronze door, it should have come from the hands of giants.

Walking through the bronze door again, I was once again impressed by the breathtaking temperament, and I saw that the façade was still engraved with that strange pattern and symbol.

Sure enough, it's the same bronze door! I exclaimed in my heart.

The door is closed, how can it be opened?

I looked around a lot, and there was no other way than the folding door, and since someone had entered it before, there must be a way to open it.

"Xiao Zhen, take it out and try it?"

I was pondering, Chen Laosan whispered.

The moment the three jade pendants were taken out, everyone's eyes were attracted, and the jade pendants turned red, the kind of bright red.

"There's a reaction!" Li Xiaobai exclaimed.

After I posed the jade pendant in the shape of Tai Chi, I held it with both hands and slowly leaned over.

The door gradually made a "squeak" sound, and the two doors slowly cracked into a gap.

The others gradually leaned in, and everyone held their breath and looked inside the door.

It is clear that there is an ancient tomb inside, and it is a very bullish imperial mausoleum, either the bones are piled up, or the burial goods are piled up in a mountain.

Speaking of this, I can't help but say a few words, in the thousands of years of history of China, there are countless tombs of large and small emperors, and there are more than 1,000 clear records, but there are not many that have not been excavated, in addition to the well-known tomb of the Qin Emperor and the tomb of Wu Zetian, the tomb of Genghis Khan, the tomb of Li Yuanhao, the founding emperor of Western Xia, and the Ming Tombs, in fact, people still ignore a king, that is, Dayu.

Dayu is the first king of our country, and there are naturally countless burial goods in his tomb.

The bronze door opened, but I didn't expect that there was only more than 300 square meters of space inside, and after looking around, there were bronze walls all around, neither inner doors nor gaps, that is to say, what we saw was all the space in the bronze door.

"What a treasure!"

Li Xiaobai didn't dare to approach at first, but when he saw us staring blankly inside, and there was nothing to do, he squeezed into half of his body.

Li Xiaobai pointed to a corner inside the door, where there was a pile of gold, silver and jade, but my eyes flashed and stared at the middle of the hall inside the bronze door.

There is a platform about two meters high and three meters wide, and you can see at a glance that this platform is made of bronze.

I muttered to myself, "Is this a coffin?" Is Dayu's coffin?
