Reborn in that autumn

"Miss, no matter what happens, we will unconditionally trust you and support you. Even if we stay here forever, we will have no regrets, let alone any grudge against you." One of them said.

"Bah, bah, bah, what's left? Spit it out twice more. Spit it out quickly. No, it will be bad if it comes true." Ye Qiu said to several people.

"bah bah bah"

"bah bah"

"bah bah bah"

"That's pretty much it, let's move on!"

"There may be a safe journey next, but? You still have to be careful. You don't know where you will encounter the trap again." Ye Qiu saw several people spitting on the ground and continued to speak.

After speaking, he turned around and continued walking forward.

This time, Li Zichen did not mutter behind Ye Qiu, but followed Ye Qiu quietly.

The six people continued walking forward.

After walking a few steps, Ye Ran asked: "Sister, I can't tell where I'm going."

"What direction do you think we are walking in, up or down?"

"If we go down, won't we go deeper and deeper, too deep? We can't show up."

"Can you get out the deeper you go underground?"

Ye Qiubian observed the environment in front and explained again; "Most of the tombs are dug out from the ground. This is in line with people's common sense, because when they were originally built, they were deliberately buried underground. And the more advanced the tombs are, the more advanced the tombs are." , the larger the underground buildings are, the deeper they are buried, and can even form the size of a palace, which is called an "underground palace."

"Not only the tombs, but also the ruins of most ancient cities were excavated from the ground. Did people in ancient times deliberately build cities underground? This is definitely not the correct answer."

"Why are the ancient cities discovered by archeology mostly deep underground? The main reason is that the so-called ancient city ruins are actually only a small part of the ancient city, and they are the foundations of ancient buildings. Since It’s the foundation. Of course it was buried underground during construction. As time goes by, it’s natural that it will be buried deeper and deeper.”

"In principle, it's just like ancient tombs."

"In the history of human civilization for thousands of years, large-scale population movements are very common, so some cities may be very prosperous for a period of time, but become deserted a few hundred years later. Those originally magnificent buildings, After losing human care, only the underground parts will gradually remain, which are those excavated by today's archaeologists.

In some existing ancient cities, many of the first floors of buildings on both sides of the road are lower than the road surface. This is due to natural dust accumulation.

Because there were no hardened roads in ancient times, the roadbed would slowly rise over time, and the interior of the building would be taken care of, and the dust on the ground would be cleared away. Over time, the ground level on the first floor would be lower than the road surface, and you would even need to walk a few steps. Go down.

"Such a situation exists in Duogu City. Some centuries-old buildings have ground floors that are even one or two meters lower than the road next to them. However, a long time ago, they were roughly the same level."

There is also a more niche factor to mention, that is, someone will deliberately bury the ancient city pool underground.For example, under the foundation of the Forbidden City in Kyoto is the foundation of the former Forbidden City. This was obviously deliberately buried when the Forbidden City was built in the early Qing Dynasty, or it could be said that the ground was raised.
