When Xu Xin and others returned to the center of Crystal City, the army of mutated creatures around Crystal City had completely retreated.

All the survivors who transplanted the tree house to Crystal City gathered around the World Tree.

Wen Guixin had not returned yet, but everyone else was there. Xu Xin told everyone in the Explorer what had just happened.

"Haha, it seems like we don't need to worry about the invasion of beasts at all, right?" Wang Lei said happily, "This city is simply invincible!"

"Yes, I just saw those mutated creatures that were affected, so honestly I thought they were domestic animals!" Zhao Xiaochuan also sighed, "This is almost nothing to worry about, right? Logically speaking, this

Are there any creatures in the world that have not been affected by the blood of giant beasts?"

"So...we are completely safe?" Qin Yunlong asked, looking in the direction outside the city.

"No, we can't take it lightly yet." Ji Chaoyang frowned, "Don't forget, this tide of beasts... does not include flying animals."

Xu Xin has actually been worried about this.

When he was around Crystal City just now, he was able to observe the surrounding sky. Fortunately, there were no animals in the sky.

"As for flying creatures..." Xu Xin thought, "I wonder if they will be affected by Crystal City. I mean, if they fly high in the sky and attack this world tree..."

Xu Xin pointed at the huge but still "infant" World Tree above his head: "Will they still be affected by Crystal City? In other words, how high up can Crystal City affect it?"

Ji Chaoyang nodded and said: "This is also something I am considering, Xu Xin, maybe you can let your bat try it. It should be able to fly higher, right?"

"You mean Ah Fu?" Xu Xin's eyes lit up slightly.

Mutated creatures like ***, Silver King, and Afu who originally belonged to the same lineup as him were not obviously affected by the mutated creatures in the beast tide that fell into coma and then directly defected.

But it is impossible to say that there is no impact at all. They are obviously more excited in Crystal City than outside Crystal City, especially ***'s performance is particularly obvious.

Nowadays, *** has basically lost all interest in the ground world, so it looks listless when it is in the tree house, lying lazily on the ground without wanting to move.

But since it came to Crystal City, its state has obviously become more exciting.

Ah Fu, Silver King, and the three pangolins are all like this.

The two little pangolins even rolled around as soon as they entered Crystal City.

Let Afu give it a try, which is the best choice.

At this time, Qi Xuefei suddenly said: "It seems that we... haven't seen many mutated creatures flying in the air, right? In the previous beast tide, we have never seen mutated flying creatures even once."

"That's true." Qin Yunlong agreed, "Before you talked about flying mutant creatures, to be honest, I had never considered this aspect."

Qin Yunhu, who was standing next to him, also nodded.

"Maybe there are no flying mutant creatures at all, or maybe it's more difficult to mutate flying creatures?"

"It's true that you haven't seen many of them, but we have seen quite a few." At this time, Wen Guixin's voice sounded from not far away.

Several people turned their heads to look in the direction of the sound, just in time to see Wen Guixin roll over from the mutated creature that had been infected.

Then the mutated creature immediately fell to the ground, as if it had exhausted all its power and turned into withered bones within a few seconds.

However, the expressions of the people around him basically didn't change, and it was already commonplace.

"Those of us who have been to the underground world have seen a lot of flying mutant creatures." Wen Guixin walked over and pointed to the ground, "The entire underground world is full of flying mutant creatures.

biology."

"Ah...I remembered. You did mention the underground world before.

There are a lot of flying insects." Qi Xuefei opened her eyes slightly and said.

"What's going on outside the city?" Xu Xin looked at Wen Guixin and asked.

"Well... those mutant creatures ran too fast, and I couldn't catch up with them." Wen Guixin shrugged, "They circled around and came back."

Xu Xin nodded.

Just as he expected.

"...Those are more like pure giant beasts than blood-patterned mutated creatures, right?"

As someone who had been chased by those things all the way, Lou Fei'er was extremely impressed by those giant beasts and bugs. She immediately said: "The bugs alone are bigger than these mutant creatures on the ground, let alone

Let’s talk about giant birds flying hundreds of meters in the air. As for those creatures, alien invaders should be unable to control them.”

"Yes, but controllable flying mutant creatures still exist."

Xu Xin thought of the group of mutated bald eagles she encountered while climbing the snow-capped mountains.

The blood patterns on those bald eagles are very conspicuous, and they are obviously beings that can be controlled.

"So, the number of flying mutant creatures may be relatively rare, but they still exist."

"Is that so..." Everyone around him was lost in thought.

Lou Fei'er pulled Xu Xin's arm and whispered: "That pterosaur stone statue can be regarded as a flying mutant creature, right?"

Pterosaur stone statue...

really.

I almost forgot about the stone creature.

Will the stone creatures created through the hands of the Long Seal be affected by this crystal city?

Everyone discussed it for a while, but couldn't come to any conclusion at all.

"Okay, okay, let's go here today." Wen Guixin smelled herself, and then showed a somewhat disgusted expression, "Those mutated creatures have just retreated, we should be able to live in peace for a while, I want to go back

Take a shower...ah! There is no water in the tree house!"

Their treehouses are now planted next to the World Tree. Although the lake is not far from here, without water being diverted, their treehouses can no longer use water freely.

"This is really annoying..." Wang Lei said helplessly, "Why don't I stop living in the tree house these days and live in the crystal house by the lake? Maybe there are any special effects of living in the crystal house...

"

"Xu Xin, is there any news from Wen Xi?" Qi Xuefei looked at Xu Xin and asked.

"Ah, there she is..."

Xu Xin told everyone what he had just learned about Li Wenxi.

Of course, he did not tell Li Wenxi's speculation about the gathering place of human branches.

If this is true, then this information is what Yingying wants to hide from them, which means that this is not information that can be publicized. Based on Yingying's intention at the time, if Xu Xin and the others knew the truth, they would probably give it to them.

They bring disaster.

So he kept silent.

Regarding Li Wenxi's current situation, no one can discuss the reason.

"Forget it, as long as we can be sure that Wen Xi is safe." Wen Guixin waved her hands and said, "Maybe Wen Xi is more comfortable than us now."

"Your sister..." Ji Chaoyang frowned slightly, thoughtfully.

"Oh, if Miss Wen Xi doesn't come back for a day, we won't have the confidence for a day." Zhao Xiaochuan lamented, "I'm a little afraid to use the explosive crossbow bolts now. I always feel that I need one less."

Wen Xi's role in the team is indeed too great.

"Xu Xin, if you want to go find Wen Xi, you can leave at any time. Just leave this place to us for protection." Wen Guixin patted her chest and said, "I'm here, don't worry."

If you find her...

Is it possible to use the teleportation array to teleport back to the underground world?

That's okay.

"I'll go find Wen Xi after the World Tree has completely grown."

Xu Xin already had a direction, so there was no rush. The top priority now was to stabilize their residence first.

"That's fine." Wen Guixin nodded, and then smelled her own scent again, "Oh, I

I can’t stand it anymore, the smell is too bad, I’m going to clean it first.”

Wen Guixin left, and the other survivor members also left one after another, either returning to their treehouses, or going to other survivors to discuss the options.

Only Xu Xin, Ji Chaoyang and Lou Feier stayed.

"Xu Xin, does your sister you just mentioned know your abilities and the role of Crystal City?" Ji Chaoyang asked Xu Xin thoughtfully.

"Well... that's it." Xu Xin nodded, "I'm also very surprised about this. But if she is really one of the previous survivors, it would be normal for her to know some things that we don't know."

"...Perhaps, there is another possibility." Ji Chaoyang looked at Xu Xin and said in a deep voice, "Did you really not think of it?"

Xu Xin was silent.

Indeed, there is another possibility.

A possibility that can explain all the changes in Xu Ying.

But that possibility is too outrageous...

Is that really possible?

"What possibilities are you talking about?" Lou Fei'er, who did not leave, was a little surprised, "What do you mean? Isn't Xu Xin's sister the previous batch of survivors? Is she the survivor of several newer batches?"
