Just like the various examinations and tests on the earth thousands of years ago, the alien invaders passed various forms of tests to select even more high-quality beings from this group of already relatively high-quality humans and their descendants.

The genetically modified people in the World Tree that Shi Wanyun climbed onto were those who passed the second level of selection.

But the selection is still not over.

The humans who passed the second batch of selection are like the students who passed the college entrance examination and entered university thousands of years ago.

Still not up to high quality standards.

So, there was a new round of selection in that world tree that was like a college of higher education a thousand years ago.

Third level selection.

According to the degree of success of genetic mutation, the status of humans who have entered the world tree is distinguished.

The three levels of selection are closely linked.

What is most surprising is that most of these three levels of selection are carried out by humans themselves.

Human beings who have gone through these three levels of selection have almost never met the real behind-the-scenes manipulators, the alien invaders.

These people even think that after passing these selections, they can get close to the alien creatures they consider to be gods, and can... return to their homeland, the earth.

They don't know that they are actually standing on the earth.

Perhaps, the selection is not over yet.

No one knows whether humans who have passed this third level of selection will go through the fourth and fifth levels of selection.

But what is certain is that this selection is not over yet.

after all……

As the controllers of this selection, those behind the scenes, those alien invaders, have not yet intervened.

It is the alien invaders who have the final say as to what purpose the humans who pass the selection will be used for.

Xu Xin finished speaking.

Shi Wanyun was no longer in deep fear, but looked at him with a very complicated expression.

Confused, confused, shocked, disbelieving, and...

Thoughts and a hint of enlightenment.

"What...are you talking about? Alien invaders? Are we still on Earth?"

Shi Wanyun still asked. She grabbed Xu Xin's arm and stared at him: "You said just now, was this a conjecture of yours? Or did you say that you have obtained evidence?"

The panic and confusion in her heart now overshadowed the fear in her memory.

In fact, the conjectures Xu Xin just mentioned basically coincided with her conjectures.

Except for the background of conjecture.

In her mind, this is not the Earth a thousand years from now, but another planet, or even a different world.

And the mastermind controlling all of this was not an alien invader, but what she saw...the monster that nearly caused her mental breakdown.

Thinking of this, the image of a monster appeared in her mind again.

Then fear arose in my heart again!

She shook her head vigorously.

Now is not the time to think about this!

She pursed her lips and looked at Xu Xin.

Now, she just wanted to know whether the background of the conjecture Xu Xin told was also his conjecture.

Still a fact.

"What do you think? Do you think what I said is true?" Xu Xin asked rhetorically.

"Is it true...?" Shi Wanyun murmured.

"Have you never had any guesses about this world?"

"Of course I have."

Shi Wanyun's hand that was tightly holding Xu Xin's arm slowly loosened its grip and hung weakly on the bed.

She whispered: "Everything here is too similar to the earth. The ecological environment and biological species are very similar. In addition to the initial data and prompt sounds, I initially thought that this was just a very realistic virtual world, and we were just a group of people.

falling asleep

people."

"Do you think so now?" Xu Xin asked.

"Of course not." Shi Wanyun shook his head, "Because the senses are so real, I have already worked hard to find flaws in this aspect, but in the end my result is that this is a real world."

"This cannot be a false world. If a false world can be so real and no different from the real world, then... this is no longer a false world, but a real world."

"So, I began to change my thinking. This world may be a parallel world of Earth, or a planet created according to the Earth's ecology."

Shi Wanyun looked at Xu Xin with a complicated look in his eyes: "When I saw that monster, I was actually more inclined to the latter."

"This is a planet created by an advanced intelligent creature to imitate the ecology of the Earth. Or on the other hand, the Earth we once lived on is actually an imitator, a shrunken version built to imitate this planet."

Ah this...

Xu Xin was a little startled after hearing this.

This woman's imagination is not ordinary...

Although it's not like he hasn't thought about these various possibilities, those thoughts basically just flashed through his mind.

"But now, you have given me another possibility." Shi Wanyun's eyes trembled slightly, "This is...the earth a thousand years later? Have you...obtained any evidence?"

She did not question Xu Xin.

"Evidence..."

Xu Xin is still a little hesitant now, whether to tell her the truth, whether to...

Treat it as one of your own.

In fact, during what Shi Wanyun told him just now, he basically trusted her.

Until just now, she lost her voice because of fear.

There is still a question mark as to whether her behavior just now was due to fear.

What could be so frightening that even recalling it would frighten her, a being who has experienced life and death and is considered the top among all survivors, to be like that?

If it weren't for fear, it would probably be a punishment for violating some kind of contract.

If that's the case, then she still can't completely believe it.

He may have already believed in Shi Wanyun. He believed that the other party would stand on his side if he was not controlled, but...

What if she's not out of control yet?

Did the genetic medicine he injected into her have a truly perfect effect?

Obviously, other people would have a high-speed metabolism similar to shedding after being injected with the drug, but she did not.

She herself said that this was because she had injected a genetic medicine into the World Tree.

It's just... the story she just told still hasn't come to this point yet.

Shi Wanyun looked at Xu Xin, saw his frowning and thoughtful expression, and immediately understood that the man in front of him still did not completely trust him.

Her eyes dimmed slightly: "I..."

She didn't know what to say. She had obviously tried her best to recall it. In order not to miss any detail, she even looked directly at the fear deep in her heart again.

She no longer knows how to prove herself.

A wry smile appeared on her face.

She has told too many lies before, so this can be considered retribution.

Xu Xin raised her hand and looked at her watch. It was already late at night.

"Perhaps, we should change places. Change places, change moods." Xu Xin stood up.

This is Zeng Tao's tree house. It's so late, so I won't occupy her tree house.

He just received a message from Zeng Tao every ten minutes, asking him why it wasn't over yet.

"...Where to go?" Shi Wanyun also stood up with him and asked softly.

"Go to my treehouse."

…

At this time Zeng Tao was in Lou Fei'er's tree

Inside the house, I lay on the windowsill and stared at my tree house.

"Why don't those two people come out..." Her little feet kept kicking the wall of the tree house.
