Xu Ying has a sister-in-law, which makes Li Wenxi more comfortable.

"So? What's going on over there with Xu Xin?" Li Wenxi asked hurriedly.

"Well, it's like this..." Xu Ying told Li Wenxi her experience on the ground without reservation.

She also felt a little guilty about her behavior in deceiving Li Wenxi here. As long as she could satisfy Li Wenxi, she would basically do it. This is why she took the risk to bring the news about Li Wenxi to Xu Xin.

"That's it..." After hearing this, Li Wenxi breathed a sigh of relief, "That Crystal City is really that powerful, that's good. I'm afraid that without my resources, they won't even be able to protect themselves...

"

As she said this, she glared at Xu Ying again, a little angry.

"How could I not consider this aspect!" Xu Ying immediately said unjustly, "I have been holding back until now, just to wait for the Crystal City to be discovered by my brother, and you will have little impact on them even if you leave.

You brought them back! How could I want my brother and the others to die!"

"So, you can tell me now why you know so much, right? If you don't tell me, you won't even think about me helping you."

With that said, Li Wenxi got off the bed, stood up, walked to the window, and looked out.

Although she had seen the scenery outside many times, it still made her pupils tremble every time.

She currently lives in a five-story single-family villa, and her bedroom is on the third floor of the villa.

The yard of the villa is very large, planted with various ornamental flowers and plants, and has swimming pools, pavilions and other facilities.

A very upscale place to live.

She looked up and forward.

It was a scene that was both familiar and unfamiliar to her.

In the distance, row upon row of high-rise buildings and extremely modern elevated highways made her almost feel like she had returned to her original world.

If she hadn't looked up and saw instead of the sky, but a piece of spar shining with white light, she would really have thought she had returned to her original world.

This... is the underground world.

The city Li Wenxi is currently in is a super big city located underground, with an area that is even as large as a small country on Earth back then.

Of course, in the face of the earth whose surface area has expanded a hundred times, the area occupied by this city is really minuscule.

Otherwise, it would not have given birth to the last branch of humankind in these thousands of years, and it has not yet been discovered.

Xu Xin's guess was correct. Li Wenxi's current location was the location of the surviving human race.

While talking in the tree house, Xu Ying had already told Li Wenxi the truth about this world. Now Li Wenxi already knows that this is the earth a thousand years later, and also knows their current situation.

The city's development has been going smoothly.

When the site was initially selected, the city chose a location rich in resources.

The rich mineral and oil resources brought many different kinds of animals that can be cultivated, and the food and oil crops that can be grown also

Growing rapidly under the illumination of the crystal dome, this underground city glowed with intense vitality at that time.

Relying on abundant resources, over the course of thousands of years, the population of the underground city has doubled from about 100,000 people at the beginning to a rate of doubling every hundred years.

Today, there are hundreds of millions of people.

When Li Wenxi heard this number, she was stunned.

While she was still shocked by the news that this was a world where humans had become extinct in a thousand years, Xu Ying told her that there was a branch of humanity underground with hundreds of millions of people!

This can no longer be called a branch. You must know that until the Song Dynasty, China did not have a population of more than 100 million! This can be said to be a very prosperous civilization!

She really didn't expect that a branch of humanity that was lingering underground could develop to such an extent!

But then I thought about it. It has been a thousand years, and it has abundant resources. It has not been discovered and invaded. It would be abnormal if it does not develop.

Of course, the gap in technology also places great restrictions on development. At least a thousand years have passed, and she has not felt that the technology in this underground world is much more advanced than her time.

It's basically the same as it was thousands of years ago.

However, a large population is a huge burden.

Xu Ying told her that the resources of this underground human world have been almost exhausted, and the population of hundreds of millions is consuming resources too fast.

The crystal blocks above the dome that emit bright white light have now basically exhausted their own energy and are much dimmer than before.

The consequence is that not only the growth rate of crops will be greatly slowed down, but the crystal block itself may not be able to survive for many years, and it will be completely dim within a hundred years.

In other words, if this human race does not return to the ground, it will directly perish within a hundred years!

The few upper-level humans who knew the secrets of this world began to rack their brains to think of ways to return to the ground.

But now that resources have been exhausted, it is almost impossible to even return to the ground, let alone the almost irresistible danger after going up.

Of course, bringing Li Wenxi here was just Xu Ying's own idea.

Li Wenxi can discover metal mineral resources, and her arrival can relieve the current pressure.

"Because I have a special status! In fact, I am not familiar with the people here, but they should listen to what I say." Xu Ying raised her lips proudly and said, "Sister-in-law, you must not know,

What do I represent here!"

"Your identity is indeed different..." Li Wenxi had already set her sights on the most conspicuous landmark in the entire city.

The weirdest thing in the whole city is not what you can see when you look up, which can illuminate this large area like a spar roof during the day, but...

In the center of the city, those two giant statues are as tall as the surrounding tall buildings!

"Those two statues outside, why are they the statues of you and Xu Xin?" Li Wenxi pointed to the statues outside, turned around and said in surprise, "I only saw it after you left. What is going on in this city?

Why are there statues built for you and Xu Xin?"
