Xu Ying informed everyone present about what she knew.

"There are... hundreds of millions of people in the underground world?"

The explorers all looked at each other with shock in their eyes.

This was a situation they had never imagined.

"But, if there are hundreds of millions of people... based on the area here, it can't bear it, right?" Wang Lei said with some difficulty.

The internal space of the World Tree is indeed large, but it is too difficult to squeeze in a population of hundreds of millions in the area of ​​a small prefecture-level city.

They are very excited to know that there are still so many humans on the earth, but... this is too much.

"Ah, of course it is impossible to bring everyone here." Xu Ying waved her hand, "The area of ​​​​this World Tree has actually far exceeded the area we originally planned. This World Tree was originally only used to undertake

The most important thing is technology and personnel, but now that the area is so large, we can take on more people."

"What do you mean by sophisticated equipment just now?" Ji Chaoyang asked.

"It's what you imagine, the most advanced weapons and equipment of mankind." Xu Ying turned to look at Li Wenxi aside, "Sister-in-law, she has already experienced the power of our weapons."

Humanity's most powerful weapon?

"Nuclear?" Xu Xin's eyelids twitched and asked.

"So that's it..." Xu Xin nodded slowly.

That's what Shi Wanyun saw, the one covered in black and full of eyes, somewhat similar to humans...half human, half monster.

This gave her some bad premonitions.

But now, they seem to have mass-produced this seed and used it on human survivors.

"Oh? What about me? What was that me like?" Wen Guixin pointed at herself and asked curiously, "What was I like then?"

They were not people in this field a thousand years ago. They basically knew nothing about mankind's most sophisticated weapons except for some knowledge out of interest.

"So strong!"

"It's normal to have different personalities."

"...It must be the fault of alien invaders." Xu Ying's eyes darkened.

At this time, Ji Chaoyang spoke.

And it was developed by alien invaders!

To be honest, there was a reason not to give away the weapons and technology, so she was relieved in her heart.

What is this hiding?

"Is it really safe here? Our survivors are still a little worried that something will go wrong here." Qi Xuefei suddenly asked.

"Didn't you develop the tree house seeds?" Ji Chaoyang asked.

"Yes." Xu Ying nodded calmly, "We have all the weapons you can think of. Of course, we no longer have satellites, so satellite-guided precision strikes are not possible, but gyro-inertial guidance is possible."

"The small tree house seeds were developed by us, but they were actually based on the development of the alien invaders themselves." Xu Ying explained, "The tree houses you live in are all mutated forms of banyan trees. This

You should know this."

Everyone needs to digest this news.

"The reason why we were able to develop the small tree house one step ahead of them is simply because the other party at that time did not have any demand for this kind of personal tree house." Xu Ying sighed and said helplessly, "For alien invaders,

It is not difficult to mass-produce small tree house seeds. As long as they want to, they can do it."

"...You just mentioned that you were lucky enough to obtain the seed of a World Tree. Could it be this World Tree?" Xu Xin pointed down.

"Ah...!" At this time, Zeng Tao on the side suddenly shouted, then looked at Xu Xin with a very resentful look, and Ma Hongwei on the side muttered in a low voice, "Doesn't that mean that my suffering during this time has been in vain?

…”

It must have been caused by that monster that traveled through time and space like her.

Xu Ying looked at the tree houses and temporary stone houses outside: "If possible, we need as many survivors as possible, so that our production efficiency will be greatly improved."

After looking around at everyone's expressions, she continued: "The small tree house you have was developed based on a World Tree seed that we were lucky enough to obtain. It is a small variant of the World Tree that can be easily mass-produced.

.”

"Ah... I'm not that anxious." Xu Ying looked out the window, "Time flows so fast here, so... we shouldn't be in a hurry for a day or two, right? We should give priority to developing this place so that we can take over the next one later.

matching facilities.”

As she spoke, her face dimmed slightly.

"But this World Tree is really a timely help!" Xu Ying clicked on the position of the World Tree on the small blackboard, with a slightly excited smile on her face, "A hundred times the flow of time is simply what we need most now.

!If manufacturing is carried out here, the efficiency will be nearly a hundred times faster than outside!"

"Ah..." Li Wenxi raised his hand, "I have indeed seen it before. Although there have been gaps in the inheritance of the underground world, it has recovered to a population of hundreds of millions after thousands of years. Their current weapons and equipment are no different from ours.

It’s a match for the most powerful weapon ever produced by mankind thousands of years ago.”

"And you survivors are the owners of these 'production workshops' and have the ability to use these 'workshops', so other survivors are also very important."

They only need to carry a seed to make a huge world tree rise from the ground, thereby controlling an area, which is very convenient and convenient.

"That's definitely impossible." Xu Ying shook her head, "We should only send more than 30,000 people to the future a thousand years later, because our team only has that many people. We sent you here in the first place just so that we can reach that era.

, we cannot send so many people to the future."

Xu Ying frowned slightly.

"Originally, we decided to use the underground world as the location of the weapons processing factory to continuously provide weapons to the ground. However, something happened down there, causing most of the underground factory to be destroyed."

Seeing that the others were also eager to ask, Xu Xin interrupted at the right time.

As she spoke, she patted her chest and showed a slightly proud expression: "The products produced by our team must be high-quality."

"That group of people at that time had experienced great changes and disasters, so it's not surprising that their personalities changed drastically. Well, let's talk about these things later. Yingying, can Zeng Tao help make weapons?"

After all, it's so small, they need to be big.

And in the room on No. 5, there are creepy half-human, half-monster experimental subjects in capsules all over the wall.

"Taozi, you were also a member of our organization back then." Xu Ying looked at her and blinked, "You were a very important weapons researcher for us back then, and so was Ma Hongwei."

"That's it..."

Ever since they came to this world and planted the tree house, they have been using the synthesis bench, weapon manufacturing bench and other workbenches in the tree house to quickly manufacture various tools, furniture, and weapons and equipment.

"Ah?" Zeng Tao was stunned, "I'm very important... what did you call me?"

This really makes me feel more and more aggrieved the more I think about it!

"No, Taozi, you are a very important person." Xu Ying said to Zeng Tao, "Your ability will play a huge role."

"So, we need to take the first step. Yingying, do you want to send the equipment and people up now?" Xu Xin asked.

"Is this easy?" Li Wenxi asked worriedly, "Isn't it already..."

"Well, but your personality is indeed a bit different from before..." Xu Ying looked at Zeng Tao in front of her, and the feeling of disobedience in her heart couldn't help but rise, "In my impression, you have always been a very cold-blooded person.

Wu Xiaololi, when I saw you for the first time just now, I almost didn’t recognize you..."

"Um...I haven't seen it, but..." Li Wenxi turned to look at Xu Ying.

Um……?

Seeing her appearance at this time, Xu Xin raised her eyebrows slightly.

"Yes." Xu Ying nodded and admitted, "It is this World Tree. It is also one of the keys to this plan. Well... now should be considered the most critical point. The flow rate at this time has really exceeded expectations."

Moreover, at this stage, she is still needed to transfer the skills and talents below. If she is gone, it will be difficult to handle.

This is actually a question Xu Xin has always wanted to ask.

She doesn't want to die yet.

"The abilities of the tree house are blocked. Only through some so-called 'activities' can the abilities of the tree house be unlocked step by step. Then a step-by-step screening process will be carried out."

"Xu Ying, I would like to ask, are the weapons in your hands just... reaching the level of a thousand years ago? You... should have higher-tech weapons, right?"

Xu Ying's eyes were a little evasive at this time, and she couldn't tell without looking carefully, and her hands were also folded in front of her chest.

But what they know is that these weapons are definitely much stronger than their current weapons!

Those weapons are all weapons from another time and space. Once she hands over those weapons, she will probably...

There is nothing wrong with saying that the tree house is a small industrial factory.

It turns out that World Tree is the original tree house?

Although the pinnacle weapon from thousands of years ago is very strong for them, against alien invaders...

"Oh, by the way, one more thing, the tree house itself has great abilities. The small tree house seeds you planted were developed by us to give you a place to live, but for some reason, you were invaded by the invaders.

The beard has been cut off.”

"The World Tree was originally developed by alien invaders who used the banyan trees on our planet to conduct countless genetic modification experiments and used them to colonize this planet.

Wang Lei on the side asked at this time, "There are a total of two million survivors in our group, and everyone has tree house seeds. Are these all developed by you?"
