In ancient times, the capital of a dynasty only had a population of several hundred thousand. The population of Chang'an City in the Tang Dynasty was conservatively estimated to be only one million.

And on this earth that was invaded a thousand years later, in addition to the underground human base, there was such a prosperous city!

However, I think so.

Since the mortality rate of the 23rd and 4th batches is not high, there may indeed be a lot of remaining humans.

Moreover, the most important thing is that if the previous batches of survivors were of the same age as theirs, it would be too easy for them to reproduce.

They are all young people between the ages of 18 and 30. They are very energetic in this regard. After there is no life crisis, they can even give birth to the next generation within a year, causing the population to skyrocket.

……etc.

Could it be that this is the reason why all the survivors are people of this age group?

Do you just want them to reproduce quickly and give birth to more humans?

"No. 228 also said that it has been nearly fifty years since the first batch of survivors came to this world. Those people are already in their seventies or eighties. Many of them have become great-grandfathers and great-grandmothers, and four generations live under the same roof."

"Although she has not seen the first batch of survivors, she has come into contact with the descendants of the first batch of survivors. There are several great-grandsons and great-granddaughters of the first batch of survivors on the World Tree."

When Shi Wanyun spoke, a faint smile appeared at the corner of his mouth, and his voice became much softer.

She seemed to have a good impression of the city, and even said that she was yearning for life in that city.

Xu Xin's eyes drooped slightly.

really……

She still didn't know the actual situation of this world, and thought it was another planet, or even a different world.

Even Xu Xin himself, if he didn't know the truth about this world, would probably feel relieved after learning that there is still a city in this world composed of humans and senior survivors.

At least, in this world, human beings still have a destination, and they still have a large number of companions. This feeling.

but……

Knowing the truth, he would not be so optimistic.

He didn't believe that the alien invaders who wiped out mankind thousands of years ago would do anything good.

"This city is called the City of Hope, as the name suggests." Shi Wanyun looked at Xu Xin, "People in the City of Hope generally believe that the people who brought them here are more advanced than humans.

Other intelligent creatures, but to them, this high-level intelligent creature is like a god, making them powerless to resist."

"However, their current comfortable life also makes them think that the survival they experienced was a thrilling selection, and only those who succeed in the selection are qualified to contact the advanced creatures in this world.

Only by living in this world are you qualified to serve them."

"They are very proud of this. Everyone has a very devout and even fanatical worship of this advanced intelligent creature and their so-called god."

Xu Xin's heart moved slightly.

This point is basically consistent with what Xu Xin said about the image in the Crystal Room.

Most of the people who were controlled by the alien invaders at that time had extremely fanatical worship for them, a worship that was almost impossible to betray.

As for Xu Xin and his team, there are only a very small number of people who are immune to mind control.

"So, every year, there will be a fierce selection in the city to select the best group of people in the city to go outside the city to serve the real masters of this world, the group of higher-level command creatures, the gods in their hearts

.”

Xu Xin showed a clear look: "That towering tree?"

"Well, but that's just one of them." Shi Wanyun looked at the World Tree that was still growing outside the window and said softly, "There are many such trees on the back side of the planet, and they are of different levels, and what I am looking for is

The one I went to is one of the highest levels."

She smiled softly: "No. 228 is very proud of this matter."

Xu Xin didn't want to laugh at all.

There are many World Trees on the back side of the planet?

From this point of view, selection in human cities is somewhat similar to the college entrance examination in the world thousands of years ago.

It is a relatively universal selection.

All people of appropriate age can participate. Those who fail will not be admitted to college, but those who are selected are eligible to go to college. And colleges are also divided into good and bad.

The World Tree that Shi Wanyun went to was one of the highest-level "schools".

"However, it is a pity that even those who were selected and came to the World Tree, most of them have never really seen any advanced intelligent creatures. Even though No. 228 has a relatively high status, they still have not seen their master, but

I just heard about it."

Having said this, Shi Wanyun's pupils trembled slightly.

A trace of fear flashed in her eyes, and she couldn't help but clench her hands in front of her, trembling slightly.

Then slowly, tremblingly, he exhaled a breath.

"You...have seen it." Xu Xin said softly.

"...Hmm." Shi Wanyun sniffed and nodded slightly, "I've seen that... monster."

As she spoke, her hands unconsciously grabbed Xu Xin's arms.

Her hands were trembling uncontrollably.

Xu Xin could also see that there was a dense layer of goosebumps on her exposed wrist.

…

That morning, Shi Wanyun was woken up by the adult.

Next to the adult, in addition to No. 228 with a reserved look, there was another girl, the girl who had greeted her before, and the hair on her body was covered with worms.

"Help her change her clothes within ten minutes." The adult's voice was very cold.

Shi Wanyun did not resist, and allowed the two girls to take off the pajamas prepared for her on the 228th last night, and then put on some very gorgeous-looking clothes one after another.

"Is this going to..." Shi Wanyun looked at the mature woman and said doubtfully.

"The master is very interested in you, so he wants to see you." The tone of the adult woman's words to her became softer, which was in sharp contrast to the coldness before, "Although the master does not care about our appearance,

But we can’t slack off.”

"Master..." Shi Wanyun murmured.

Is she about to meet the real owner of this place?

2

The 28th also told her last night that it was an extremely glorious thing to meet the master here, but it was also an extremely difficult thing. Among the people she knew, except for the supervisor, no one else

Qualifications to meet the host.

Unexpectedly, she, who had just come here, would be summoned directly?

Next to her, No. 228, who was arranging her clothes, was also stunned and even stretched his neck a lot.

The other girl was also so shocked that her "black hair" twisted wildly and even got wrapped around Shi Wanyun's arm.

Shi Wanyun's body trembled and he almost kicked the girl away.

Holding back her physical discomfort, she asked these two people to help her put on this cumbersome outfit.

She looked at the mirror aside.

She looked like an exquisite doll at this time.

The adult looked at Shi Wanyun and nodded with satisfaction: "That's right. You two have done a good job. You can use the genetic medicine first next time."

The latter sentence was said to the two women No. 228.

The two women suddenly woke up from the shock just now, with surprise on their faces: "Thank you, Mr. Supervisor!"

"Okay, we should go."

The adult woman nodded to Shi Wanyun, turned around and walked out of the room.

The clothes on his body were not very comfortable and even felt restrictive, which made it difficult for Shi Wanyun to move for a while.

"Follow me quickly!" No. 228 immediately urged, her eyes already filled with envy and jealousy, "Oh my god, you can meet the master the day after you come here! Follow me quickly, hurry up, Wan
