This discussion lasted for a long time.
Three hours later, Xu Xin came out of Ji Chaoyang's room.
Chang Yin followed Xu Xin out of the house.
Chang Yin also knew that there might be very serious danger here in the near future, so he decided not to let Xue and Xiao Hong come over for the time being.
Xu Xin and his friends were unsure about the dangers that might come in the future, so he naturally wouldn't let Xue and Xiaohong take the risk.
But he himself will stay first.
Because he has the power to control the stone statue, he can help resist attacks from possible alien invaders in the future.
"I won't live inside this World Tree anymore. I'd rather live in the Crystal City outside." Chang Yin said to Xu Xin, "A hundred days in this World Tree is equivalent to one day outside. I don't want to be away from Xue and Xiao Hong for that long."
"Yeah, that's fine."
The stone beasts are also outside, and the long seal can be left outside so that they can be controlled at any time.
Outside the World Tree, Chang Yin controlled the group of stone behemoths into the area covered by the canopy of the World Tree and entered the Crystal City.
Then, these stone statues fell down one by one in the Crystal City, like huge stone statues in the Crystal City, motionless.
Changyin randomly chose a crystal house.
"I'll just stay here." Chang Yin said to Xu Xin.
"Okay, if anything happens, just let the statues outside move, and we'll know."
Xu Xin did not give Chang Yin the authority to enter and exit the World Tree at will.
Although he felt that Chang Yin himself was trustworthy, he still hadn't figured out where his petrification ability came from.
Therefore, even though the group of petrified beasts that Chang Yin can control is a very powerful force for the World Tree, Xu Xin cannot regard him as his own for the time being.
Back in the villa in the World Tree, Xu Xin sat on the sofa and sighed deeply.
"Ah, you're finally back. It's been two days." Li Wenxi looked down from the second floor. "Have you dealt with the Changyin issue?"
Although Xu Xin and the others only chatted with Chang Yin for three hours, they went out to pick up Chang Yin and just sent Chang Yin away, all of which took place outside the World Tree.
This process took at least half an hour outside, so naturally two days were spent inside the World Tree.
"Well, it's taken care of for now." Xu Xin rubbed his temples and felt a little headache.
"Chang Yin? Ah, what's the situation with that guy? Tell us quickly!" Lou Feier's voice also came from the second floor.
Then, the two girls went downstairs and sat next to Xu Xin.
"Uh... Changyin himself isn't really sure either."
Xu Xin said with some tiredness.
"Hmm? Really? Where is Changyin now? And that monster was with you before, right?" Li Wenxi asked curiously, "What did you talk about?"
"Changyin has moved out. As for the monster, it promised Changyin that it would teleport to where Xue and Xiaohong are and tell Xue and Xiaohong what's happening here."
Since Changyin agreed to stay here, he naturally had to tell Xue and Xiaohong that he would not be going back for the time being, otherwise they would be worried.
"Xue and Xiaohong? Has Xiaohong been found?" Lou Feier asked in surprise.
As one of the six people who explored the underground world together at that time, Lou Feier naturally remembered very clearly that Chang Yin did not return to the ground with them because he did not find Xiao Hong.
"What's going on?" Li Wenxi grabbed Xu Xin's arm and asked.
"Um... are you two the only ones here?" Xu Xin looked at the second floor. "Is there no one up there?"
"I came here to play by myself. I don't have any fixed tasks right now." Lou Feier waved her hand. "Don't look up there. There's no one there. Oh, there's a little guy sleeping there."
She must be talking about Coco.
"Oh? Your current task is to maintain order here." Xu Xin glanced at her.
"Yes, but the people here are very obedient." Li Wenxi explained for Lou Feier, "They don't need to be managed at all."
Some of them are survivors who have escaped death and are very satisfied with this place and cherish their lives here. Some of them are from the Wei family, a military family in the underground world.
There are less than a thousand people in total, so there is really not much to worry about.
"When there are more people, you will be busy."
"Then I'll take this opportunity to have some fun. Oh, stop talking about this and explain the situation to us! I heard that all the stone beasts have entered the Crystal City and are in charge? Have we really taken control of those stone beasts?"
After the stone statue attacked, there were people observing the outside situation at all times on the control console in the underground area. This part was assigned to Zhao Xiaochuan.
If there are any changes in the outside world, he will also inform all explorers.
"Well, it's under control."
Xu Xin briefly told the two women about Chang Yin's situation.
"Ah? You left Xue and Xiaohong down there again?" Li Wenxi was puzzled. "It would be great to bring them up here. Why do you have to leave them down there?"
"We can't guarantee our own safety, so Chang Yin will naturally not let his wife and son be in danger." Xu Xin sighed.
"This isn't right!" Li Wenxi was a little unconvinced, "We are much safer here than in the underground world, right?"
"Yes now, but what if alien invaders attack?" Xu Xin asked back.
"Isn't it still early..." Lou Feier couldn't help but retorted in a low voice.
"Morning? Heh..."
Xu Xin glanced out the window, in the direction of the monster.
It's not early.
Why did the monster make such a huge group of stone beasts march in an orderly manner from a distance step by step
Although there is a restriction that you cannot freely teleport around the World Tree, the more important thing is...
This is more noticeable.
That's right, that monster was using his own method to realize the plan it had mentioned, the plan to make the World Tree conspicuous and then be besieged by the army of alien invaders!
Such a large number of stone beasts entered the Crystal City and were conquered. This is a very dangerous signal for alien invaders!
The military strength of humans on Earth is gradually expanding, and there are even giant beasts!
Or is it a giant stone beast that they are completely unfamiliar with!
If alien invaders discovered this situation, would they pay more attention to this world tree
Of course they will.
"this… "
Upon hearing this, Li Wenxi and Lou Feier's pretty faces immediately changed color.
"... Do you think the alien invaders have guessed that the monster is hiding here?" Li Wenxi shook his lips and said.
“… They may not be sure, but they are definitely suspicious.” Xu Xin nodded slightly.
"Yeah... That monster was exposed because of this World Tree. Now that it has escaped from the alien invaders, where can it run to?" Lou Fei'er's face was also a little solemn. "If I were an alien invader, I would definitely suspect this World Tree first!"
Yes, this is also one of the conspiracies of the alien invaders.
The monster told Xu Xin and Ji Chaoyang that even if it didn't come, the alien invaders would definitely have doubts about this world tree.
So make sure they are prepared.
"Wow... What should I do? I'm getting more and more nervous..." Li Wenxi grabbed Xu Xin's arm and squeezed it, "It feels like there are only a few days left before the exam, but I haven't reviewed any courses yet..."
What a wonderful metaphor...
"What are you afraid of? We have a hundred times more time!" Although Lou Feier said this, her forced smile clearly showed that she was also a little nervous.
Xu Xin was not so nervous for the time being.
Now they have a certain degree of self-protection ability. A hundred times the speed of time flow, and a super-hypersonic missile with a nuclear weapon, this is no joke.
Unless they really launch a large-scale attack, they will not pose any threat to this side.
But judging from the current civil unrest of the alien invaders that the monster mentioned, it is not an easy task to send troops to attack them.
Of course, there will probably be a lot of harassment from Xiaobo.
Maybe it's coming soon.
"In short, all we can do in this regard is to improve ourselves as quickly as possible," said Xu Xin.
Then he frowned slightly again.
"What are you thinking about?" Li Wenxi saw his expression and leaned over to ask.
"Oh... it's about us."
After that, he and Ji Chaoyang asked Chang Yin and the monster many more questions.
Xu Xin also asked the doubts in his mind.
But... he didn't get the answer he wanted.
First, he asked the monster about the altar.
As a result, he learned from the monster that the altar was not built by the monster.
It was only after it discovered that Xu Xin and his group were sent to the future that it discovered the two strange altars nearby.
There are two of them nearby, one near Xu Xin’s tree house and the other near Ji Chaoyang’s tree house.
It can feel the energy of time and space from the altar, as well as a special energy.
When the monster felt this special energy, it was very surprised because it felt very familiar with it.
This energy is almost identical to the special energy of those humans in the underground city who can move after being petrified and even control the stones around them that it has been studying out of curiosity for the past few decades!
This is true for both altars.
The energy of the altar at that time was still very overbearing. It would petrify and devour any creature that entered the altar!
That’s right, it was swallowed up, and was directly swallowed up by the concave ground.
But it is not death, but petrification. If you want to rescue the devoured creatures, you must sacrifice the flesh and blood of these creatures or the most special parts of their bodies to free the petrified creatures from petrification.
…
"Ah, you mean the altar surrounded by hills?" Li Wenxi asked in surprise, "It's not far from where we found the giant's head, right?"
"Yes, it's that altar. Ji Chaoyang also had a similar altar at that time. We relied on this altar to revive intermediate mutant creatures and then kill them, and that's how we got the first and second place in the standings at that time." Xu Xin said.
"Ah, I know that." Li Wenxi nodded, "You told me before."
"Hey? What are you talking about..." Lou Fei'er was confused, "Are you talking about hunting activities?"
She had not heard of this matter.
At that time, she was still in District 187. Later, she wanted to kill Xu Xin and was captured. She was not trusted for a long time, so naturally she had not heard of this incident.
"It's like this..." Li Wenxi explained it to her briefly.
"Ah... there is such a magical place?" Lou Fei'er was surprised, and then her eyes turned, "Wait... then... if we want Chang Yin and the others to recover their human bodies, don't we need... human flesh and blood and special parts of the body?"
Logically speaking, this is true.
In particular, the special energy in the Changyin family's bodies is the same as the energy in the altar.
Therefore, the monster ordered people to make mysterious sounds to tell Changyin's family that there was an altar on the ground, and through sacrifice they could restore their human bodies.
Therefore, after coming to the ground, Changyin's family left Xu Xin.
Later, Xu Xin found traces of sacrifices made by Chang Yin's family in the altar.
However, the Changyin family seemed to have used the props in their hands for sacrifice, so they did not succeed. They were also tricked by alien invaders into the underground world to conduct experiments on petrified monsters.
"Horrible... I remember you said that if you want to break a stone statue and let living creatures come out, you have to kill at least hundreds of its kind, right?" Li Wenxi murmured, "Then Changyin and the others..."
According to this ratio, if they want to transform from stone statues back into humans, they need at least...
Sacrifice hundreds of humans.
Chang Yin also fell silent when he learned about this.
But he also said that it would be great to be able to turn back into a human, but it didn’t matter if he couldn’t, at least the stone statue’s body was safer now.
"Hmm... How did the long seal turn into a stone statue?" Li Wenxi asked again.
“…I don’t know.” Xu Xin shook his head.
"Ah? Didn't Changyin tell you?"
"I told him, but... he said he turned into a stone statue because of the first group of survivors." Xu Xin said.
When he first met Chang Yin, he had already revealed some information to Xu Xin.
The first survivors did some pretty horrible things to the family.
The first group of survivors were the first group of humans brought by monsters thousands of years ago. They were the only group of survivors who survived together in groups at the beginning.
After all, it is the first batch, the selection is still immature, and the selection format is very different from the current survivor selection.
In such a harsh environment, people survive in groups, there are no laws, and everything is based on force. The evil in the nature of the strong will be infinitely magnified.
It’s not that all people are like this, but there were quite a few of them among the first batch of strong survivors.
And it just so happened that the people who went into the underground and saw this family were exactly this kind of people.
Changyin Yijia didn’t say what those people did to him.
But Xu Xin suddenly thought of those terrifying inscriptions carved on the stone table in the underground city.
Among the messy carvings, there are few legible characters.
They are all demons
Kill me, I want to die
You will not die well.
When Xu Xin saw it at that time, he felt horrified.
Changyin's family was also petrified in the process. Then the survivors who entered the dungeon were all turned into monsters whose life was worse than death by Changyin's family. Then they stayed underground forever, in the flooded dungeon.
Therefore, Chang Yin always felt that it was those survivors who petrified him.
It's just that they overplayed their hand and ended up killing themselves.
But the monster said that this was impossible, and those first survivors could not have such ability.
"Hey, wait a minute!" Li Wenxi interrupted Xu Xin and asked in confusion, "Weren't the first group of survivors here forty-eight years ago? Was Changyin still a human forty-eight years ago? Did he also experience the disaster a thousand years ago? Who is he? A survivor from a thousand years ago? Lived until fifty years ago? Is he a lackey of the alien invaders?"
“… I don’t know. At least from Chang Yin’s words, he didn’t know about this. He was even extremely shocked that the world was now a thousand years later.”
