At that time, she had not given him this very strange feeling.

But now I have this feeling when I meet her.

This means...

Her current condition is indeed getting worse!

"Brother...I can't do it. I'm about to..."

Xu Ying's eyes were trembling, and she was obviously panicking.

"this……"

Xu Xin was also a little at a loss.

Not really...

He reached out and tried to grab Xu Ying's arm.

Then Xu Ying quickly dodged it.

"Don't touch me!" Xu Ying took two steps back. "Don't touch me! Otherwise, you might be..."

Be wiped out of the world together?

Xu Xin's outstretched hand paused.

“Brother, I…”

“Relax, relax…”

Xu Xin could only look at her nervously and worriedly.

She is the main contributor to this operation.

The success of the operation has not yet been confirmed, so how can we let her leave with the regrets of all the people in another time and space?

but……

Xu Xin was completely helpless and could do nothing.

Fortunately, the world doesn't seem to want to take her away at this time.

Her condition, after worsening, gradually began to improve.

Her pale complexion gradually turned rosy.

Xu Xin tried to grab her hand.

It doesn't feel like before.

He breathed a sigh of relief: "It seems that you have survived this time."

"I……"

Xu Ying waved her arms, and her eyes gradually brightened.

"I think I really made it through!"

She jumped twice more on the spot.

"Ah, he's not dead! That's great! He's not dead!"

Seeing her like this, Xu Xin couldn't help but laugh.

"Alas, but I probably won't live much longer. Besides, I won't be able to enter the World Tree again."

Xu Ying said with great regret.

"No, I think..."

Xu Ying looked at the new world tree outside the window.

"You can enter the World Tree."

"Ah?" Xu Ying was stunned, then waved her hands, "No, it's impossible. I know my body well."

"Every time I enter the World Tree, time and space around me become extremely chaotic. That's why Coco was so afraid of me before."

"In my current state, even if I teleport, I'll end up in the same state as before. If I still want to enter the World Tree, I'm completely doomed."

She said regretfully, "What a pity! I thought I could live a little longer in the World Tree. But it's okay. I just saved my life, so every extra second I live is worth it."

Xu Xin turned to look at her: "Yingying, don't forget, we can control the flow of time within the World Tree."

"Yeah, I can control it. How...ah! You mean!"

Xu Xin's method is very simple.

Bring the speed of time in the World Tree back to the same level as outside the World Tree.

In this way, when Xu Ying entered the World Tree, it would not be considered a sudden travel between two spaces with different time flow rates.

After Xu Ying entered the World Tree, she adjusted the time flow rate of the World Tree back to normal.

This way, she can enter the world tree.

It's like... there's a bug in this world.

"When I think about it this way, it seems to be possible!" Xu Ying's eyes lit up.

"Of course, the method I'm thinking of isn't 100% reliable. For example, if the speed of time changes within the World Tree, will you be affected?"

Xu Ying thought for a moment and said, "It shouldn't be a big problem. The changes in the flow rate of time in the same space and time actually make no difference to us. After all, time itself is a relative concept."

"The so-called change refers to the change in the speed of time relative to the outside world. For us inside the World Tree, nothing has changed in essence."

"Of course, there might be problems, but... I'm willing to take that risk!"

She became more energetic at this moment.

Because, if she could enter the World Tree, this separate small space, her lifespan might be extended a hundred times!

“It works, it really works!”

"Wait until we've determined the situation with the alien invaders, if it's really solved..."

"I will live in the World Tree and never come out in my lifetime!"

Xu Ying suddenly had a feeling of... "having someone to rely on when old."

Although I lost the ability to teleport, I felt a lot more at ease.

"Haha, let's go out and see what's going on."

"Um!"

The situation outside was basically consistent with what Xu Xin had just observed.

The alien invaders' chariots could no longer be found at this time.

At the speed of the chariots, they shouldn't be able to travel very far in an hour, but at least they should be out of the range of Crystal City.

The surrounding is very peaceful.

Nearly a hundred giant beasts were lying in the Crystal City.

They are not dead, they are just a little tired, so they are resting.

As for those petrified giants, they were lying motionless on the outskirts of Crystal City, like a group of simple stone remains.

"By the way, where's Chang Yin?"

Xu Ying looked at the giant stone beasts and asked, "Isn't that the stone man's seal controlling them?"

"Well, he should be resting too."

You don't have to worry too much about Changyin's safety.

He is a controller, not a participant.

And he had said before that there was no need to worry too much about his safety, because if there was really danger, he would just hide in the crystal building.

Furthermore, he can use his ability to control rocks to create underground passages to hide in.

"So...it seems we can call the others back."

Xu Ying looked around and said, "It's safe here for now."

Xu Xin thought about it, found a crystal house, and set up the teleportation coordinates inside the crystal house.

Although the portal will be limited by the internal space, for example, the Silver King, who is now very large, will no longer be able to pass through.

But this coordinate is responsible for teleporting people, which will be much safer.

"Okay, let's go get them all here...wait a minute."

Xu Xin frowned and looked at Xu Ying: "Now... you can't even use the coordinate portal?"

"Ah? Of course not." Xu Ying immediately waved her hand and said, "This kind of transmission with the help of external objects will not have any effect on me."

"Are you sure?"

"Of course, I'm very afraid of death!"

"Forget it, you should wait here for me. I'll go call them over."

"What are you waiting for? Don't forget I still need to use these coordinates to go to the alien invaders' lair! I already said it's okay!"

"I really don't trust what you're saying now."

"I...it was my fault before, but this time I'm really fine..."

"Okay, then... let's go."

"Um!"
