Siheyuan: I have a system and I smile with satisfaction

Ni Daguo said in the beginning, "Chief Ma, I am not a professional. I just like to read books. Expert Hao may have said a lot of good things about me, but if you really can't find anything, you can't blame me."

The old man stood up straight, patted his chest and said, "Don't worry, I won't complain. I'm already very happy that you can come."

Chief Ma actually didn't hold out much hope. Many experts had come to check, but even a well-known expert in the industry like Hao couldn't find the cause. Asking Ni Daguo to check it out was like trying a last-ditch effort. What if?

This is the possibility that we are blocking.

Ni Daguo knew what was going on, but he still had to pretend to check it out.

After he left that night, he never came back.

He didn't know what it was like at night. Although he had strong mental power, he didn't have night vision. Without glasses, he couldn't see what was underground.

Even if you can see through it, you can't feel it like during the day.

Watching it in broad daylight gives a completely different feeling.

This tiankeng is really huge, and the area of ​​an entire palace is not small.

Not only is there an indoor palace, there are also places to play, such as the imperial garden, playground, indoor hunting ground, swimming pool and so on.

It's like a palace.

Ni Daguo put the palace into a warehouse without looking it over carefully, but there were quite a few flower beds and flower pots, and there were still some seeds and roots of flowers and plants in them.

But because the palace was moved underground, there was no one living there, no one to take care of it, and without the sunlight, it gradually became quiet.

Including the steps, there are seeds and roots of these flowers and plants.

After the enemy spies blew up the tunnel entrance, some steps were destroyed, and some of the seeds and roots of these flowers and plants fell to the ground.

At this time, it actually grew out.

It is indeed an example of a thousand-year-old seed still being able to grow.

These vegetation are obviously different from those in the world today. You have to know that these are species from thousands of years ago.

After thousands of years of changes, either extinction, mutation, or hybridization, etc., it has become completely different from before.

This place has been carefully fenced off for fear of being destroyed.

This is really worth studying.

Ni Daguo opened his mind and gradually began to search for the names and origins of these vegetation.

Sure enough, after searching, he found out that he had read an ancient book, which was one of the books he got on the black market, and there was a description of these vegetation.

It was a short-lived dynasty thousands of years ago, which was buried in official history for unknown reasons.

But it does exist in unofficial history.

However, this ancient book truly records everything that happened at that time. Later, the last emperor fled here. The palaces were both above and below ground.

Mutually connected.

Later, after changes, the buildings on the ground disappeared, and the underground palace closed automatically and became a crypt. Some of the bones inside also indicate that this was actually a tomb, the final cemetery after the fall of a dynasty.

Ancient books also provide detailed records of the vegetation at that time, with illustrations.

When Ni Daguo told this story, Section Chief Ma was stunned.

"How do you know this?"

Ni Daguo said without any special expression: "I said, I used to read books in a rather chaotic manner, I don't know when I read it, I thought it was a wild history legend, but unexpectedly, it turned out to be true. Now it fits. Didn't the history experts say that there were some incoherence in that period of history? That's the history, and it just happens to be coherent."

Section Chief Ma was excited. They had been studying for several months but had not been able to figure out what these vegetation were.

According to Ni Daguo, this was vegetation that only existed in the imperial palace at that time. The dynasty was autocratic and did not allow outsiders to grow it.

A rare species that is only available in the imperial palace.

This makes sense. The reason why there is no such vegetation in any records of later generations is that the imperial palace must have been completely destroyed before the royal family fled.

There is also a seemingly true record in history that says a fire destroyed all records of the former imperial capital.

Not only was it destroyed by humans, but it was also probably set on fire.

We can also deal with the situation where these vegetation are being extinct.

Who would have thought that it would reappear a thousand years later.

"Can we still find the book?" Section Chief Ma asked even more excitedly.

"I'll go back and look for it, maybe I can find it, but if I can't, you can't complain." Ni Daguo reminded again.

Chief Ma naturally said he would not complain. After all, Ni Daguo was able to tell what species these plants were, and the time was probably enough to get the job done.

This is the veil that can lift the veil of that history.

Someone nearby took note of everything Ni Daguo said.

Ni Daguo walked down the earthen steps and thought about the marble steps he saw when he first came here. When he got to the underground palace, the steps were all made of white marble.

Now it's all soil.

Then, Chief Ma showed Ni Daguo the broken marble. Ni Daguo nodded and said that these should not be difficult for Expert Hao, and he should be able to figure it out in time.

Sure enough, Expert Hao and his team have determined the approximate age, a thousand years ago, probably between one thousand and fifteen hundred years ago.

This is also consistent with what Ni Daguo said about the vegetation being from that era.

Ni Daguo walked down the stairs and counted the number of steps. They were all built according to eighty-one steps.

It implies the number of six lines. All the things below were collected by Ni Daguo in the warehouse. Naturally, nothing would be left behind. It was a whole.

However, the underground palace was built in an excellent geographical location, with an underground river passing through it. The underground river has long dried up, but Ni Daguo saw the dry well built in the underground palace of the warehouse and the traces of streams flowing through.

It is also possible that water from the river above was once directly introduced here.

Before the royal family was destroyed, this was also their hiding place.

But after more than a thousand years of changes, these traces can no longer be detected on the surface.

Or maybe the detection equipment is a little bit lacking.

Ni Daguo put on the glasses given by the system and observed carefully this time.

Even if this underground palace cannot be given to them, it would be considered as a reward if they could discover something.

Everyone else thought that it was because the sunlight was too strong, and Ni Daguo was doing it to block the glare. Only Ni Daguo knew the purpose of it.

With the help of glasses and the traces of water flowing in the underground palace in the warehouse, Ni Daguo drew places where there may have been underground rivers or surface rivers.

This busy schedule took three days.

Sometimes Ni Daguo glared at Expert Hao, because he knew that it was impossible for him to go back so quickly after arriving.

When the painting was finished, Ni Daguo pointed at these places and said, "Dig it and see what you can find."

The places shown in the painting include not only the location of the underground palace, but also outside the underground palace, after all, the rivers are connected.
