There is still no clear clue as to where Chang Yin's petrification ability came from.
Although the monster used the petrification ability and the altar to cause some trouble to Xu Xin and the others, it also had only a vague understanding of the petrification ability and the altar.
So the matter was left unresolved for the time being.
At least from the current point of view, Changyin is still on their side, and that is enough.
"Hmm..."
Coco climbed down from the second floor and crawled into Xu Xin's arms.
"Coco, do you know what a petrified creature is?"
Xu Xin suddenly asked Keke.
It is basically certain that this little guy Coco has experienced time travel.
Moreover, it is very likely that it does not come from the past, but from the future.
Then it is very likely that it knows something.
In particular, when the group of stone creatures approached the World Tree, Coco had always been very confident in telling Xu Xin that those petrified creatures were not dangerous.
“…嘤?” Coco tilted her head, her eyes filled with confusion.
Pretending very much.
But Xu Xin won't be fooled by it.
"You little guy, tell me quickly, where did those stone creatures come from?" Xu Xin grabbed Coco by the scruff of the neck.
"Hmm?" Coco let him pick her up. Her big tail wagged twice, and she still tilted her little head with an innocent look on her face.
"Hey, what are you doing?" Li Wenxi hugged Keke and said, "Why are you asking Keke? How can it possibly know?"
She rubbed the back of Coco's neck.
"嘤!" Coco nodded her little head in agreement, waved her little paws at Xu Xin, and raised her little head again.
This little guy...
"Pfft, you're desperate and trying anything possible." Lou Feier couldn't help but laugh.
In her opinion, it was too ridiculous to interrogate Coco.
Although this little guy Coco is somewhat magical, how could he possibly know such things
Xu Xin was speechless.
Li Wenxi and Lou Feier didn't know yet that Coco came from the future.
If he hadn't been unable to use his mind-reading ability on Coco, he probably wouldn't have known the origins of this mysterious little guy.
"Forget it." Xu Xin shook his head helplessly.
Coco didn't want to tell him. He couldn't torture the little guy to extract a confession.
"Coco, I just have one question, are those stone statues safe?" Xu Xin brought Coco back and asked while rubbing its little belly.
"嘤!" Coco nodded her head very firmly.
"You are so confident, and yet you say you don't know." Xu Xin pinched its ears and said speechlessly.
"Bing!"
Coco jumped out of Xu Xin's arms, stood up, waved her little paws at him twice, and then ran to the second floor.
"But does it really know?" Li Wenxi asked in surprise.
She felt that Xu Xin would not let go for nothing.
"Who knows?" Xu Xin spread his hands, "Maybe it knows, this little guy is very mysterious. But it..."
"So can we trust those stone creatures outside now?" Lou Feier suddenly asked, "Those stone creatures would attack us before."
Xu Xin and his team had indeed fought with the stone creatures more than once.
"It shouldn't be a big problem now."
Xu Xin glanced at the second floor.
He chose to believe Coco.
From the moment he met the little guy, it had never missed.
Perhaps, it has already seen everything in the future.
Who sent it from the future
…
Time passes quickly inside the World Tree.
This is the case in the World Tree. Because there is no transition between day and night, the concept of time becomes vague.
Fortunately, they had already set standard time.
They even set up a clock tower in the center of the entire living area, with a huge clock on all four sides to show everyone the current time.
At eight o'clock in the morning and eight o'clock in the evening, a bell would ring to let everyone know how many days had passed according to the time outside.
More than half a month has passed inside the World Tree since the arrival of the long seal.
During this half month, nothing major happened and everything was going on as planned.
"Hey, why hasn't Yingying come back yet?"
When the clock struck eight in the evening, Li Wenxi was chatting with Lou Feier and a few other girls in the room.
"According to the time outside, she should have been out for more than four hours, right?" Zeng Tao counted on her fingers.
Zeng Tao has not been idle during this period.
She has enlarged the missile system developed by Ma Hongwei, making it a giant missile nearly twenty meters long, with its power increased by dozens of times.
Now, the explorers have planned to install this missile device outside the World Tree.
"Maybe it will take even longer." Jin Yue put down the cards in her hand and said, "I win."
"Ah!" Lou Feier stared at the cards that Jin Yue put down with wide eyes, and then threw the cards in her hand onto the table in frustration, "Oh, I don't want to play anymore, I keep losing!"
What they were playing was a card game from the underworld.
"What? Can't you afford to lose?" Zeng Tao teased.
"Lilililil~"
"This time when Yingying comes back, she should bring us a lot of people who survive in the underground world, right?" Shi Wanyun also put down the cards in her hand and said softly.
"Well, then our place will become lively!" Li Wenxi said with a smile.
"It's quite lively now." Lou Feier said, standing up to get a glass of water, leaning against the table.
"Now... I always feel like something is missing." Zeng Tao ran to the window and looked out, "The population density is too small. This is called... a vast land with few people!"
Because of the power of the tree house, the productivity of each of these survivors is extremely high, so now this living area has the prototype of a modern city.
But there are only about a thousand people living in this city.
"Yeah, let's bring more people. It seems like they were too excited when they were building the city before and built it too big. Now it's like a ghost town." Jin Yue said as he tidied up the cards on the table.
"By the way, where's Xu Xin? Why hasn't he come back yet?" Lou Feier looked towards the gate. "It's already eight o'clock in the evening. Does he want to stay out all night?"
The sky outside the window was still very bright, making her words unconvincing.
"Ah, he was called away by Ji Chaoyang." Li Wenxi explained, "It seems to be because of the survivors living here."
"What happened?" Shi Wanyun asked.
"I'm not sure either." Li Wenxi shook his head.
"Then why didn't you go with us?" Zeng Tao asked in confusion, "Aren't you all having meetings together?"
"I don't want to go." Li Wenxi waved his hand. "It's enough for me to take them to the underground world to collect resources. I don't want to care about those trivial matters. Let Xu Xin and Ji Chaoyang worry about it."
"That's right. It's impossible to control everything."
…
"So, this is what it is, what do you think?"
Sitting opposite Xu Xin were Ji Chaoyang and Qi Xuefei.
"Well... keeping it a secret from them is indeed a solution. I think we should tell them the truth."
After the stone behemoths arrived and settled down, some people covered with fur often appeared outside the Crystal City.
They appear and disappear mysteriously, their movements are very agile, just like well-trained scouts, and their hiding places are also very secretive.
It's a pity that time flows a hundred times faster inside the World Tree. No matter how agile their movements are, they can still be seen clearly even if they are slowed down a hundred times when viewed from the World Tree's control console.
Although a long time has passed inside the World Tree, only a few hours have passed outside the World Tree!
This situation happened in just a few hours, which has to make people vigilant.
Xu Xin and his friends asked the monster, and the monster told them that those low-level mutated humans with fur all over their bodies were the survivors who were eliminated after failing in the survival challenge, and some were directly captured from the living survivors.
Even the eliminated humans are intelligent creatures after all, so the alien invaders "recycled" them and turned them into the furry appearance they are today.
Although this appearance of being covered in hair is unacceptable to humans, for alien invaders, this appearance of humans is much more comfortable than their own appearance.
It is precisely because of this that they turned humans, who were not dead but eliminated, into this appearance.
"Some of those people originally worked for me and were assigned to work under the heads of various regions. You should have seen them. But now I've run away, so those hairy humans are all under their control."
This is what the monster told them when they went to find it just now.
In other words, those guys covered with fur are the lowest-level lackeys of the alien invaders.
"The alien invaders have sent people to monitor us." Ji Chaoyang said, "As for the reason, it should be what we thought."
The World Tree, the giant stone beasts, and... that monster.
The combination of these factors is enough to make the alien invaders pay special attention to this area.
But perhaps because there has been no trouble, there has been no movement outside the World Tree in the past few days.
"Our situation is really becoming more and more dangerous." Xu Xin pondered.
"So, perhaps we should tell the people living here about our true situation." Ji Chaoyang looked out the window.
Although the survivors and the people in the underground world already knew the current situation here, and initially had some concerns about the alien invaders, with the development of military force during this period, they were all very confident in protecting the World Tree.
Especially when the giant stone beasts arrived and Xu Xin and his friends claimed that these beasts were their companions, they became even more confident.
These days, after confirming that the petrified creatures were harmless, those who were unwilling to live in the World Tree moved outside the World Tree, and many of them even became familiar with Chang Yin.
Each of them feels that there is a bright future for development within the World Tree.
But Xu Xin and his friends also hid some things from these people.
For example, the existence of monsters, and for example... the suggestion made by the monsters.
That, the suggestion of driving alien invaders off Earth.
"I think, whether it is implemented or not, we should tell them about this plan." Qi Xuefei said, "This plan, as well as the fact that we are being targeted, can make these people nervous again. They are too relaxed now."
Qi Xuefei sighed in annoyance, "Some of them have even started asking me about pregnancy and childbirth. Given our current situation, they actually want to do this."
…
Xu Xin was stunned at first, then he couldn't help laughing and said, "Isn't this the case before? So did you tell them?"
"I'm not a gynecologist, so how would I know about this kind of thing?" Qi Xuefei shook her head helplessly.
"I see you are quite knowledgeable. Your medicine has helped us a lot." Xu Xin said with a smile.
If it weren't for Qi Xuefei's medicine, he and Li Wenxi would never have dared to be so presumptuous.
"How can killing and giving birth be the same?" Qi Xuefei couldn't help but roll her eyes slightly.
Xu Xin looked at Ji Chaoyang, one eyebrow slightly raised: "You two live together, so you should..."
"Stop." Ji Chaoyang's face was dark and he made a pause gesture, "We are not here to talk about this kind of thing this time."
"Okay." Xu Xin spread his hands. "Then tell them something. To be honest, I have a feeling that it's only a matter of time before they come to destroy us, and it won't be long before it happens."
"Yes, and as long as the enemy attacks, our passive defense will be of no use. We must move the battlefield and attack the enemy's lair."
Although the size of the alien invaders' army has not grown much in the past thousand years, it is still very large. After all, it is a fleet traveling through the universe.
It is impossible to win in a head-on confrontation, and even if you are on the defensive, you will be lucky if you can hold on for a while.
"Tell them something. Our leisurely days won't last long." Xu Xin said.
…
Soon, all the residents of World Tree knew about the current situation of World Tree.
Xu Xin and his team did not tell them about the plan. The fewer people who knew about this kind of home-stealing plan, the better.
Otherwise, the news will leak out in some way at any time.
They told them that the alien invaders would most likely attack the World Tree en masse, and even told them that this was not just suspicion but that there were already signs of it.
This caused an uproar in the group.
"Oh my god, are we going to be attacked by a space fleet?!"
"A fleet of alien invaders that has crossed the galaxy will attack us en masse?!"
"This this this..."
"No... It's not that exaggerated, right? Don't we just have one world tree? Aren't there a lot of alien invaders?"
"This is no ordinary world tree!"
“They don’t know either…”
"Who said that? There might be a traitor among us who has spread the news a long time ago. Isn't it said that alien invaders are the best at brainwashing?"
"Hey, hey, hey, don't stir up trouble!"
"You guys have too little confidence. Our weapons are so powerful now! They are nuclear fusion weapons! Tell me who can withstand them!"
"You're talking as if there's nothing on the other side..."
“… I feel like we can’t go on like this any longer!”
"Yeah, I've been so comfortable these past few months that I almost forgot that this is a world full of dangers."
"Mom, the ground is so dangerous, I want to go back underground..."
"I knew it was dangerous on the ground, but I didn't expect it to be this dangerous!"
"I'm a little excited. Why? We have enough weapons now. If they dare to come, we will fight them!"
"What are you all looking at? Don't embarrass our Wei family!"
…
The incentive effect is very good.
Almost no one among the survivors complained. After all, although they had lived here carefree for several months, they were the ones who finally survived the bloody selection.
They won't complain about the danger. Those who would complain about the danger would have died in previous disaster activities.
And the residents of the underground world rarely complain.
After all, they are from the Wei family, a military family, so naturally they are not so fragile.
They came here to retake the surface.
Of course, some of their family members are still very worried and want to return to the ground.
But when Xu Xin told them that even the underground human base was not safe now, they gave up the idea.
Xu Xin is not exaggerating.
Because there is a possibility that the current underground human base has been exposed, and the possibility is not small.
Initially, a large number of the survivors who were planted by monsters in the underground human base returned to the ground.
And after the monsters "defected", those people are now on the side of the alien invaders.
Although Xu Ying had followed the monster's instructions and removed all the underground world's transmission devices,...
Even if the alien invaders from the other side of the Earth have no interaction with these survivors and basically do not communicate with them, it is only a matter of time before this underground world is exposed.
Information can always be spread in various ways.
By then, the underground world might not be safe either.
"I don't know what the results of Yingying's trip to the underground world were this time."
As Xu Xin was walking back, he began to worry about Xu Ying's situation.
"Hehe, are you worried about me? I'm here personally, what are you worried about, brother?"
Suddenly, a familiar teasing voice came from behind Xu Xin.
He was startled and immediately turned around, and saw Xu Ying with a smug smile on her face.
“… You’re back.”
Xu Xin smiled, but then the smile on his face gradually faded.
Because this time, even he could vaguely feel that something was wrong with Xu Ying.
It's a wonderful feeling.
This feeling was somewhat similar to the feeling he had when he traveled through time in the Crystal Palace and wandered back to the past.
"… The degree of space-time disorder in your body has worsened." Xu Xin frowned.
"Ah..." Xu Ying looked down at herself, then raised her head and smiled, "It's okay, it will be fine in a few minutes."
"you… "
"Oh, let's go back first!"
Xu Ying pushed Xu Xin into the villa in front of them.
"Ah! Yingying, you're back!"
All the women in the villa stood up and gathered around.
"You've been gone for a really long time!" Li Wenxi exclaimed.
"Hehe, for me, it's only a few hours." Xu Ying said with a smile.
"Huh? Why do you feel like you have a..." Lou Feier looked at Xu Ying suspiciously, and couldn't help but touch her body, "Strange feeling?"
It seems that Lou Feier has also become slightly aware of the disorder of time and space.
Coco had the most exaggerated reaction.
The little guy was originally on the first floor, but as soon as Xu Ying came back, he ran to the second floor.
"Hmm..."
At this time, its two little paws were holding the railing on the second floor, and it was looking over here from a distance.
Xu Xin frowned even more.
"What's so strange?"
Xu Ying waved her hand nonchalantly, and then said excitedly: "I gained a lot from going to the underground world this time! You will never guess!"
