They asked Wei Shishi to try to gather some important people first, and when they go next time, they will bring those people to the ground.

After all, the world tree is much safer than the underground world.

But Wei Shishi also needs time to do these things, no matter how fast it is, how fast can it be?

So the two of them planned to just go there and take a look every day.

And for every day that passes in the outside world, more than three months will pass in the World Tree.

They have too much time.

"Ah, you mean the period until dawn the next day outside?"

Xu Ying looked at the sky inside the World Tree.

"Yeah, that's right!" She shook her fist, "Besides manufacturing weapons in large quantities during this period, there really is nothing else to do. Maybe I can finally relax for a while!"

Xu Xin shook his head: "Don't talk about the last word. As long as you don't do anything extraordinary, there shouldn't be any big problems."

"Who knows, the laws of the world are ruthless." Xu Ying said, taking off the bracelet she had been wearing on her left hand, staring blankly at the bracelet for a few seconds, and then reached out and handed it to Xu Xin.

"This is...?" Xu Xin took it and was surprised.

Space bracelet?

"It's a weapon from that time and space." After Xu Ying handed the bracelet to Xu Xin's hand, she felt her whole body relax and said with a smile, "It's a very powerful weapon. It's the only one I know that can... destroy crystals.

weapons."

A weapon that can easily destroy crystals?!

"You mean, the kind of crystal in Crystal City?" Xu Xin's throat moved and she asked a bit silly.

"Besides that kind of crystal, what else could it be?" Xu Ying continued walking along the stream, "That is a very powerful weapon. We used alien technology and earth technology and resources to finally create the weapon.

.Now we don’t need it for the time being, so don’t take it out.”

As she said that, Xu Ying tilted her head slightly and looked at Xu Xin: "When you take it out, maybe it's time for me... to disappear completely."

"...Leave this choice to me?" Xu Xin was silent for a few seconds, then shook his head with a wry smile, "You are really..."

"You are the most suitable, brother." Xu Ying emphasized the word "brother", "I don't want to put my life in the hands of others."

As she spoke, she sighed and then smiled.

"I have no future and I don't dare to commit suicide. Even though I have lived for so long, I... in short, if I need it, it's up to you to help me choose, my brother!"

With that said, she patted Xu Xin's shoulder.

Xu Xin shook his head. He didn't dare to look at what was inside, so he just put it away: "Do you think I can make a choice? You are my sister."

It would be too cruel for him to kill his own sister with his own hands.

"Of course you can make a choice, brother, because I am not your sister." Xu Ying said with a smile.

Xu Xin was speechless.

"Your real sister has not yet reached this age." Xu Ying continued walking along the stream, "And I am just an old monster who has lived for more than three hundred years, a sister destined to be unable to be with you."

They are just fakes that exist in the same time and space."

Fake…

"I must die before your real sister comes here."

Xu Ying's tone dropped a little.

"Otherwise, not only me, but your real sister will also disappear from this world along with me."

Two identical people cannot exist in the same time and space, otherwise a paradox will occur, causing the laws of the world to directly eliminate the existence of this person.

It directly makes the existence clear, no one will remember this person's name anymore, and all traces of him/her in this world will be erased.

"Don't think you'll forget us. If something like this really happens, you won't forget us."

Xu Ying said to Xu Xin.

"Anyone who has experienced time travel will never forget those whose existence has been erased. Don't think that this is a good thing, because forgetting is a kind of salvation. Keeping such memories will always live in pain.

middle."

Xu Xin was silent.

She is talking about herself.

"So, brother, take action when it's time to take action, otherwise your real sister will be buried with me." Xu Ying said very heavy words in a relaxed tone.

"...What if you time travel to the future?" Xu Xin pursed her lips and made a suggestion, "To the very distant future..."

"How is that possible?" Xu Ying immediately waved her hand to reject it. "I don't have the technology to travel to a very distant future. Jumping a thousand years at a time is already the limit. Moreover, in your current state, it is still very easy to live for a thousand years.

Bar?"

"Then go back to the past..."

"Of course that's impossible! Do you want the world to collapse again? And..." Xu Ying smiled bitterly, "In my current state, I can no longer experience time travel."

Is this actually the case...

"Then... when will my sister come to this world?" Xu Xin asked.

"According to what my brother said, it should be...three years later." Xu Ying replied.

Three years from now...?

"There is still plenty of time, just live in the present." Xu Xin took a deep breath and smiled, "At least now, you can still have fun with everyone."

"Well, you're right!"

Xu Ying handed over the bracelet as if she had put down a burden, and her whole state felt much more relaxed, "Then I'll go have a drink with them!"

Looking at Xu Ying's back, Xu Xin felt a little heavy in her heart.

"...Fortunately, in this World Tree, we have a hundred times more time."
