Now that the equipment is complete and the technical staff are all there, weapons production can be put on track.
First of all, the people from the underground human base brought up by Xu Xin and Xu Ying must teach all the survivors how to make and use these machines.
Then, the survivors gave priority to the production of weapons, because their productivity, thanks to their own abilities, far exceeded that of ordinary people in the underground world.
During this period, Ma Hongwei, Zeng Tao and others had to transform and develop various weapons to increase their power.
Relying on the hundred times faster flow rate of time within the World Tree, a steady stream of weapons will be rapidly manufactured with extremely high efficiency, appearing on a super large scale in a very short period of time.
After some discussion, everyone finalized the plan and began to implement it.
Xu Ying first brought the humans from the underground world base outside the tree house into the World Tree and told them the goals they should accomplish.
Then, he gathered all the survivors.
Seeing so many people from the underground world coming here, the survivors became excited instantly.
They simply couldn't believe their eyes.
"Oh my god, these... these... are they the people from the underground world that the elders mentioned before?"
"That is... the human race that has been passed down from thousands of years ago to the present day?"
“It’s actually true!”
"Shit, when have the Explorer elders ever lied to us?"
"that… "
On the other side, people were not very excited. After all, the survivors looked like ordinary humans, and those living in the underground human base had seen too many such creatures.
They were just very curious about the origins of these people living on earth.
As the two groups of people gradually communicated with each other, both sides became more and more shocked by each other.
"Oh my God, you... you really have lived underground for thousands of years!"
"Travel...travel through thousands of years? You have all experienced time travel?!"
"Oh my god, I'm suddenly very curious about your human base..."
"Wait... So, they are actually... from the same era as our ancestors thousands of years ago? Hiss—"
There was a lot of interest on both sides.
The explorers naturally wouldn't let the two gangs get down to business as soon as they met. There was plenty of time inside the World Tree anyway.
Thus, a grand welcome banquet began.
It was already evening outside the World Tree, and it was much darker inside the World Tree. Lights and fires were lit up one after another, and it was very lively.
Xu Xin took a sip of the grain wine that some survivors had brewed during this period, looked at the extremely joyous scene in front of him, and exclaimed: "Who would have believed that we could actually hold such a grand banquet in this world."
Thinking back to the life and death incident some time ago, the scene before him seemed like a dream.
"Hehe, that's because you're always out and haven't stayed in the World Tree for a few days." Li Wenxi sat next to him, her pretty face flushed from the alcohol, leaning on his shoulder, "We've been making a lot of noise this past month..."
“Is that so…” Xu Xin smiled and touched Coco in his arms.
"Hmm... burp!" Coco lay on her back in Xu Xin's arms, her little belly bulging high, looking like she was full, and she even burped a little.
Everyone's life in the World Tree is really comfortable.
I don’t know if the dozen or so survivors living outside the World Tree would regret it if they knew that life inside the World Tree is so easy and comfortable.
However, counting from the time the World Tree matured, only one day had passed outside. Even if those outside regretted their decision, they could just come back in.
"Yeah, it's really comfortable here... I was wondering, with this world tree here, should we still resist?" Li Wenxi was a little drunk, and murmured her current thoughts, "Yingying said that there is no danger in the world tree... As long as we live in the world tree forever, there will be no danger... Hmm..."
As she said this, she could hardly open her eyes.
"You really can't drink that much." Xu Xin pinched her cheek.
“Um… who… who said that! I drank three cups, that’s a lot! Um…” Li Wenxi shouted, then hugged Xu Xin’s arm and started humming again.
Xu Xin was speechless. This was just ordinary brewed wine, not distilled wine. The alcohol content was about the same as beer. It would be good if it could reach 5 or 6 degrees.
She became like this after drinking three cups. This girl's alcohol tolerance is really low.
Xu Xin sent Li Wenxi back to her own room. Looking at her rosy sleeping face, he couldn't help but pinch it, then walked out of the room.
This area is really... becoming more and more lively.
In the distance, the laughter of countless people could still be heard.
Xu Xin sighed.
Just like what Li Wenxi said just now, if they could live in this world tree forever and enjoy this kind of life forever, then...
There's something uninspiring about trying to take back Earth from alien invaders.
"You don't think that as long as you live here, you can be isolated from the world and have no worries, do you?"
Xu Ying's voice came from behind Xu Xin.
He turned around and saw Xu Ying standing there, staring at him.
"I don't have such an idea for the time being, but..."
Xu Xin glanced at Li Wenxi's villa, then at the people who were laughing not far away: "They seem to... more or less have this idea."
As a member of the explorers, Li Wenxi could have such thoughts after living in this world tree for a month, let alone other people.
If Xu Xin also lived so peacefully in this world tree for a month, he might have the same idea.
The joyful scene before his eyes, which seemed to have not appeared for a long, long time, really touched him.
"… You have not experienced the disaster that happened thousands of years ago, nor have you been enslaved by those monsters, so it is normal for you to have such thoughts."
Xu Ying and Xu Xin were walking side by side along the stream.
"As long as they are still on this planet, we can never relax. As long as they are still on this planet, our situation will never be safe."
Xu Xin turned his head slightly to look at Xu Ying, and saw that her expression was a little confused, but more of it was worry.
"You drank too?"
"I didn't make trouble with you guys." Xu Ying rolled her eyes and sighed, "I'm afraid I... will become obsessed with this feeling."
"What's wrong with being infatuated?" Xu Xin said with a smile, "At least now, we still have plenty of time."
"Hmm..." Xu Ying struggled for a moment, then glared at Xu Xin, "Don't tempt me! Although your proposal is very tempting, but..."
She sighed and looked at the fish in the stream: "I'm afraid my time is running out."
Xu Xin's eyes narrowed slightly, and after a moment of silence, he said, "As long as you don't do anything out of line, the situation won't get worse. Isn't that what you said?"
"I... I don't know either." Xu Ying squatted down and gently slid her hands across the surface of the stream. "Actually... I only have my brother as an example to learn from. He was indeed like that, but I don't know if I will be like him."
Xu Xin knew that the "my brother" she was talking about was the Xu Xin who disappeared in the image and in front of Xu Ying.
but…
"What about the others? Don't you have more than 30,000 people in your team? Aren't they all..."
"… They were all involved in important research and technology transfer, and had a serious impact on the direction of the world. So when they disappeared, there was no warning at all. They were gone all of a sudden, and there was no way to use them as a reference. No…"
Xu Ying sat by the stream and hugged her legs: "Maybe I will be like them, and I will disappear from this world completely at some point."
Xu Xin wanted to comfort her, but didn't know what to say.
He really didn't understand anything about this matter.
In the end, he could only sit next to Xu Ying: "Those people are like that because they have a huge impact on the world. You haven't done anything serious, so how could you be like that?"
"elder brother… "
Xu Ying leaned her head on Xu Xin's arms for half a minute, then stood up.
"Oh, I lost my composure, I lost my composure!" Xu Ying rubbed her eyes. "Seeing those people happily holding a welcome party, toasting each other, I feel a little anxious!"
Xu Xin also stood up and said, "No matter what happens in the future, at least in the next one or two months, we can relax a little."
The one or two months that Xu Xin mentioned naturally refers to the one or two months inside the World Tree.
According to Ji Chaoyang's prediction, nothing will happen at least tonight.
According to the time inside the World Tree, it is about forty days.
Moreover, during this period of time, Xu Xin and Xu Ying had no plans to go to the underground world again.
Before they left, they discussed the situation in the underground world with Wei Shishi.
They asked Wei Shishi to try to gather some important people first, and then they would bring those people to the ground when they went there next time.
After all, the world tree is much safer than the underground world.
But it takes time for Wei Shishi to do these things, no matter how fast she does it, it won’t be that fast.
So the two of them planned to just go there and take a look every day.
For every day that passes in the outside world, more than three months will pass inside the World Tree.
They really have too much time.
"Ah, you mean until the next day when the outside world gets light?"
Xu Ying looked at the sky inside the World Tree.
"Yeah, that's right!" She clenched her fist, "During this period of time, apart from mass-producing weapons, there is really nothing else to do. Maybe I can finally relax for a while!"
Xu Xin shook his head: "Don't say anything about the end. As long as you don't do anything out of the ordinary, 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. She stared at the bracelet for a few seconds, then handed it to Xu Xin.
“What is this…?” Xu Xin took it and was shocked.
Space bracelet
"It's a weapon from that time and space." After Xu Ying handed the bracelet to Xu Xin, she felt relaxed and said with a smile, "It's a very powerful weapon. As far as I know, it's the only weapon that can... destroy the crystal."
A weapon that can easily destroy crystals? !
"You mean, the kind of crystal in Crystal City?" Xu Xin moved his throat and asked a somewhat silly question.
"What other crystal could it be other than that?" Xu Ying continued to walk along the stream. "That is a very powerful weapon. We used alien technology and Earth technology and resources to finally create this weapon. We can't use it right now, so don't take it out."
As she spoke, Xu Ying tilted her head slightly and looked at Xu Xin: "When you take it out, maybe that will be the time for me... to disappear completely."
"... Leave this choice to me?" After a few seconds of silence, Xu Xin smiled bitterly and shook his head, "You really are..."
"You are the most suitable one, brother." Xu Ying emphasized the word "brother" very much, "I don't want to put my life in the hands of others."
As she said this, she sighed and then smiled.
"I'm useless and I don't dare to commit suicide. Although I've lived for so long, I... Anyway, if the time comes, you can help me choose, my brother!"
As she spoke, she patted Xu Xin's shoulder.
Xu Xin shook his head. He didn't dare to look at what was inside. He just put it away first: "Do you think I can make the decision? You are my sister."
It is too cruel to let him kill his own sister with his own hands.
"Of course you can choose brother, because I am not your sister." Xu Ying said with a smile.
Xu Xin was speechless.
"Your real sister hasn't arrived yet." Xu Ying continued to walk along the stream, "And I am just an old monster who has lived for more than 300 years, a fake who is destined to not exist in the same time and space as your real sister."
Fake...
"I have to die before your real sister gets here."
Xu Ying's tone was a little depressed.
"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 space and time, otherwise a paradox will occur, causing the laws of the world to directly eliminate the existence of this person.
It will directly clear the existence, 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 this is a good thing, because forgetting is a kind of salvation. Keeping such memories will always make you live in pain."
Xu Xin was silent.
She is talking about herself.
"So, brother, you should take action when the time is right, otherwise your real sister will be buried with me." Xu Ying said very heavy words in a light-hearted tone.
"…What if you travel into the future?" Xu Xin pursed his 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 the very distant future. Jumping a thousand years at a time is already the limit. Besides, with your current state, living for a thousand years should be easy, right?"
"Then go back to the past..."
"That's impossible! Do you want the world to collapse again? And..." Xu Ying smiled bitterly, "In my current state, I can no longer travel through time."
Is this really the case
"Then... when will my sister come to this world?" Xu Xin asked.
"According to my brother, it should be... three years later." Xu Ying replied.
Three years later
"There is still plenty of time, 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!"
After handing over the bracelet, Xu Ying felt like she had put down a burden, and her whole state felt a lot more relaxed. "Then I'll go drink with them!"
Looking at Xu Ying's back, Xu Xin felt a little heavy in his heart.
"… Fortunately, we have a hundred times more time inside this World Tree."
