Xu Xin suddenly felt that the whole thing had become extremely complicated, far beyond his previous imagination.
He thought that the information he obtained in the Crystal Palace was the truth.
But now it seems...
The truth is much more than that.
In fact, the fact that so many humans are sent from the past to the future to participate in this somewhat strange survivor plan already explains one thing.
At least now, in this world thousands of years later, alien invaders definitely have the ability to travel through time.
But when did they start to possess this ability? Did they possess it before invading the Earth, or was it an ability that they developed during the millennium of development
Thinking of the self with blood tattoos on his face that he had just seen in Shi Wanyun's memory, Xu Xin already had his own ideas in mind.
At least in that time and space, three hundred years after the invasion, alien invaders could travel through time and space.
Otherwise, it would be impossible for him to see that photo in this time and space.
If you want to be bolder, then...
These alien invaders may have already reached the point where they can control time and space.
Before they invaded Earth, they had the ability to travel through time.
It's just that it may not be used normally, and even if it is used, it is top secret. After all, the ability to travel through time and space is a double-edged sword. Once something goes wrong, it will cause the collapse of time and space.
Therefore, the enslaved humans at that time had no idea that the other party had this ability.
They studied hard and finally, relying on the technology given to them by the alien invaders, they figured out a way to travel through time and space.
But as humans who are exposed to time travel for the first time, they know very little about it and are unaware of its taboos.
And in this case, they had very serious consequences.
The future direction of the world has changed drastically, and the space and time they are in is also facing collapse.
The collapse of time and space is very obvious. The flow of time and spatial distance will be distorted. Those alien invaders must have noticed this.
These alien invaders who have long possessed the ability to travel through time and space are familiar with this phenomenon and know the cause of this time and space chaos. They know that it is someone who has traveled through time and space and has excessively influenced the past, causing the future they are in to collapse!
Knowing the causes of the crisis, they took appropriate countermeasures.
This countermeasure is most likely the same as that taken by Xu Xin's imaging team at the time.
Go back to the past.
They cannot let everyone disappear with the collapse of time and space, they need to let some people go back to the past to find out the truth about the turbulence of time and space.
Their mission is to prevent themselves in another time and space, the invaders from another time and space, from repeating the same mistakes.
"The same person cannot exist in the same space and time..."
Xu Xin thought to himself.
"So... are the individuals who return to the past all young individuals of the new generation... Or, are they also like this side, sending away the self in the past time and space, and then returning to the past."
Thinking of this, a somewhat terrifying idea suddenly came to his mind.
Now he knows that the Xu Xin in the image and himself are two completely different people.
What he does will not affect the other person, and the other person will not affect him.
And the alien invaders probably know this too.
Since they are different individuals, if they do not affect each other...
Then wouldn't it be better to just kill myself in this world and take my place
This is the easiest way.
Methods like sending someone to the future are just too troublesome.
Xu Xin and his team did this because they didn't know whether their past selves in this time and space would affect them. Moreover, they were also preparing to take back the world in the future.
But alien invaders don't need to go to such trouble.
They only need to send the new generation of individuals back to the past and kill themselves without the other ninjas knowing, and they can directly replace them.
As for the fact that they do not exist in this time and space, will they cause the world to reject them and dissipate
Didn’t Yingying also not disappear, and even persisted for a thousand years
They... maybe there is a special way that allows them, who do not belong to this time and space, to survive in this world.
If that's the case...
Among the alien invaders living on the other side of the Earth, perhaps a small part of them are...
Invaders from that collapsed time and space!
And the one Shi Wanyun saw might be one of them!
Because it has a photo of Xu Xin with bloody marks!
Moreover, its self-talk was also heard by Xu Xin.
Oh, there should be no blood lines on his face now, right
This clearly means that it has seen the Xu Xin of the past, the Xu Xin with bloodshot eyes on his face at that time.
It... Obviously, like the image of Xu Xin and Yingying who took Wen Xi away, it came from that collapsed time and space!
Xu Xin rubbed his eyebrows in annoyance.
It feels like... things are really getting more and more difficult.
"The more you understand... the more difficult it becomes." He sighed softly.
"... Can you explain what you meant by going back to the past?" Shi Wanyun suddenly asked.
Xu Xin's mumbling just now caused a huge wave in her heart.
Back to the past, the past time and space...
She stared into Xu Xin's eyes, waiting for his answer.
Xu Xin looked at her.
He felt that he could now trust the person in front of him.
He could indeed tell her the truth as he knew it.
But before that…
"Did you rest well?" he asked.
"Okay, I'm full of energy now." Shi Wanyun nodded.
"Show me what happens next, and I will tell you the truth as I know it."
"good."
Shi Wanyun came up immediately.
…
Shi Wanyun visited many places in the residential area of No. 5.
Except for her pavilion, which was not allowed to be entered, she visited all other places.
She found the source of the stream.
It is the very edge of this area, gushing out from the wall like a fountain.
"Although the space of the World Tree is not small, this place is also considered the core area." No. 5 has been following her, taking her to wander around the garden. At this time, he gently tapped the boundary wall of the entire area with his hand and said, "Do you know where this is?"
"The core area... Could it be the trunk of the World Tree?" Shi Wanyun guessed.
"That's right." No. 5 smiled, "This is the trunk of the World Tree, the heart of the entire World Tree."
“… No wonder there’s water flowing.”
"Well, this water flow is not artificial water, but water drawn from the World Tree." No. 5 leaned over and scooped up a handful of slightly cold water. "This water is not ordinary water, but water filtered by the World Tree. The water quality is very clean, and it also contains the ability to gradually change the body."
As she spoke, she lifted the water to her lips and sipped.
Then he raised his head, shook his hands gently, and said with a smile: "This water alone has the ability to eliminate fatigue and prolong life."
"Is he that strong?" Shi Wanyun was a little unconvinced.
“You can try it.”
Shi Wanyun also squatted down, scooped up a handful of water and sipped it gently.
It was very sweet, and even though she wasn't very thirsty at the moment, the taste of the water still made her eyes light up.
At this moment, the introduction also appeared in her mind.
World Tree Spring Water (Purple): This is spring water that can be drunk directly. After being filtered and blessed by the World Tree, the water quality has undergone a drastic change. It contains some of the energy of the World Tree. Drinking it can eliminate physical and mental fatigue and prolong life.
"Purple-level water?"
This really surprised her.
"Purple level...? Ah, it's the ability of a survivor, right?"
No. 5 was a little confused at first, then said with relief: "I remember now, I was also able to see the grades of some props back then. It was almost fifty years ago, and I have forgotten a lot."
Shi Wanyun looked at her with some surprise: "You can't see the grade and introduction of the items now?"
"Of course." No. 5 responded with a chuckle, "This is only an ability you get during the survival selection. It disappears after the selection. Come to think of it, I was a little uncomfortable with it back then."
"Is that so... Will my ability disappear in the future?" Shi Wanyun's eyes moved slightly.
She wanted to ask No. 5 if she had any special abilities and whether her special abilities had disappeared.
But the words came to my lips but I didn't say them.
Although her special ability is not a combat ability, it can be considered a trump card. If she asks this question, it is equivalent to telling the other party that she has special abilities.
Moreover, since the other party has never asked about special abilities, he probably doesn't know about it.
Speaking of which, among this fifth batch of survivors, those with special abilities are also rare.
"It will definitely happen." No. 5 walked along the stream with Shi Wanyun. "Our first four batches of survivors were all like this, and the fifth batch should be no exception."
"... You all should have a tree house at that time, right? Your tree house was later..."
"No." No. 5 said, "There is an area specially designed for us to live in, and there is also a world tree."
She looked around and asked, "Do you still need your little tree house?"
really…
The area she owns is more than enough to plant a hundred or eighty tree houses.
Shi Wanyun felt even more conflicted.
She really... wanted to own such an area...
But the prerequisite for owning such a paradise is to kill Xu Xin.
"Well, it's almost time to send you to where you should go."
“… Yeah, okay.”
Although she was not ready yet, Shi Wanyun had no choice but to follow No. 5.
The direction she was walking in was the attic that she had never entered.
Looking at the scenery around her, she slowly let go of the worries in her heart.
Until then... let's consider it.
The monster also said that her mission was to kill Xu Xin, but if she failed to complete the mission, she would need to lurk beside him and look for opportunities.
We'll see what happens then...
…
"Have you already decided to kill me at this time?"
Xu Xin suddenly asked.
He opened his eyes.
The two of them still had their foreheads touching. Shi Wanyun did not close her eyes, but stared at him in a trance.
Seeing Xu Xin open his eyes, she immediately looked away: "You are my savior, I..."
Xu Xin laughed: "I don't believe it. That place is not only for you, but also for me."
Shi Wanyun pursed her lips, raised her head, no longer pressed her forehead against Xu Xin, and said with a slight tilt: "... a little bit, just a little bit."
Xu Xin turned his head to look at the World Tree outside the window, and then looked at Shi Wanyun with interest: "I now doubt very much that if we had not planted this World Tree, you would not be on my side."
Shi Wanyun was silent for a moment, and finally nodded gently: "This is... the most important reason. This world tree has shown me the possibility of human beings. Perhaps human beings can really defeat that kind of monster and turn the tables."
Xu Xin shook his head and said, "You are really honest."
"I just don't want to lie to you anymore." Shi Wanyun looked at him and said, "When this world tree appeared and the mysterious voice began to sow discord between the various regions, I knew that this tree was definitely extraordinary."
“What would you have done if I hadn’t grown this tree?”
"… You have subdued me, but it seems that you have no intention of killing me as long as I obey. I will continue to lurk around you and look for an opportunity."
"Looking for a chance to kill me?"
"… Um."
"You're being honest. But I understand."
Xu Xin looked at the World Tree outside.
"Being the owner of a garden like this and being able to command most of the people, this kind of life is beyond the lives of 99% of people a thousand years ago, not to mention in this dangerous world."
Now, he is even more looking forward to the growth of the World Tree.
No wonder it is called the World Tree.
He was also wondering why there were so many World Trees. In his impression, shouldn't there be only one tree called World Tree in each world
Now it seems that the name "World Tree" is not as exaggerated as he imagined.
It is called this name because this tree itself is equivalent to a small world!
"No, you don't understand." Shi Wanyun pursed her lips and looked at Xu Xin, "You don't understand."
"… What do you mean?" Xu Xin looked at her puzzledly.
"The information I'm going to get next is the key to changing my mindset." Shi Wanyun said, and without waiting for Xu Xin to ask, she grabbed his arm and stuck close to him.
She looked at Xu Xin and said, "I, Shi Wanyun, am not so mean as to kill my savior just for a comfortable place to live."
Xu Xin looked at her deeply and closed his eyes.
…
No. 5 took her to the attic.
"What you are about to see is one of our core secrets, and it is also a secret that you must keep."
No. 5 suddenly stopped and stopped Shi Wanyun who wanted to go further inside.
"Remember, you must never tell anyone else about what happened here, even if it's someone here, even if it's No. 228, whom you're familiar with."
Her words were serious.
"Number 228 is not possible either..." Shi Wanyun was a little nervous.
This is really a core secret.
She has only been here for one day, and she has already known such core secrets. She is under a lot of pressure.
"I understand." She nodded.
"Okay, follow me."
No. 5 walked towards the door of the pavilion. She did not reach out to push the door, but the door slowly opened as she approached.
A wave of hot air came over me, mixed with a strange smell.
And everything in the attic made her slowly open her mouth.
What is in the attic is totally different from what it appears to be.
From the outside, the attic looks like an ancient Chinese building, very elegant.
But the interior...
It is a strong sense of steel flood!
Complex, giant machines were running in front of her, making sounds of operation.
She walked in, and the smell of metal mixed with blood became stronger.
It made her hold her breath for a moment.
However, that was not what she cared about.
“This… This is…”
She raised her hand and pointed forward.
On the wall in front of us were two large transparent capsules more than two meters high, neatly arranged with mines.
Each capsule is filled with a transparent pale red liquid, and inside the liquid is…
One by one, sleeping in strange shapes...
A monster that makes people physically uncomfortable.
