Xu Ying informed everyone present what she knew.
"There are... hundreds of millions of people in the underground world?"
The explorers looked at each other, their eyes filled with shock.
This was a situation they had never imagined.
"But, if there are hundreds of millions of people... considering the area here, it can't bear it, right?" Wang Lei said with some difficulty.
The space inside the World Tree is indeed large, but it is too difficult to squeeze in hundreds of millions of people in a small prefecture-level city.
They are very excited to know that there are still so many humans on Earth, but... it's too much.
"Ah, of course we can't bring everyone here." Xu Ying waved her hand. "The area of this world tree is actually far larger than what we originally planned. This world tree was originally only used to receive the most important technology and personnel, but now that the area is so large, we can take in more people."
"What do you mean by high-tech equipment?" Ji Chaoyang asked.
"It's what you imagine, humanity's most advanced weapons and equipment." Xu Ying turned her head to look at Li Wenxi beside her, "Sister-in-law has already felt the power of our weapons."
"Ah..." Li Wenxi raised his hand. "I have indeed seen it. Although the inheritance of the underground world was interrupted, it has recovered to a population of over 100 million after a thousand years. Their current weapons and equipment are comparable to the strongest weapons we had a thousand years ago."
Mankind's most powerful weapon
"Nuclear?" Xu Xin asked, his eyelids twitching.
"Um... I haven't seen it, but..." Li Wenxi turned to look at Xu Ying.
"Yes." Xu Ying nodded calmly, "We have all the weapons you can think of. Of course, we don't have satellites anymore, so we can't carry out satellite-guided precision strikes, but we can use gyroscope inertial guidance."
“So strong!”
Everyone needs to digest this news.
They were not experts in this field thousands of years ago, and knew basically nothing about humanity's most advanced weapons, except for some knowledge out of interest.
But what they know is that these weapons are definitely much stronger than their current weapons!
Their equipment needs to be directly upgraded to the ultimate level!
"Originally, we decided to use the underground world as the location of the weapons processing factory to provide a steady supply of weapons to the surface, but something happened down there, causing most of the underground factories to be destroyed."
Xu Ying and Li Wenxi looked at each other, both of them revealing a hint of helplessness.
"But this World Tree is really a timely help!" Xu Ying pointed at the location of the World Tree on the small blackboard, with a slightly excited smile on her face, "A hundred times the time flow rate is exactly what we need right now! If we carry out production here, the efficiency will be nearly a hundred times faster than outside!"
Will the weapon manufacturing in the underground world be transferred to the World Tree
"Is this easy?" Li Wenxi asked with some concern, "Hasn't the bottom already been..."
"It's easy, don't worry." Xu Ying said confidently, "The core components are not destroyed, and those that are destroyed can be rebuilt within a month. One month in this world tree is only six or seven hours in the outside world."
"Ah...!" At this time, Zeng Tao on the side suddenly screamed, and then looked at Xu Xin with great resentment. Ma Hongwei on the side also muttered in a low voice, "Doesn't that mean that I have suffered in vain during this period of time..."
She has been researching a giant cannon that can be carried anywhere, but now that more powerful weapons are available, all her efforts would be in vain.
The more I think about it, the more aggrieved I feel!
"No, Taozi, you are a very important person." Xu Ying said to Zeng Tao, "Your ability will play a very huge role."
"Ah?" Zeng Tao was stunned. "I am very important... What did you call me?"
"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, ah, and so was Ma Hongwei."
She turned to look at Ma Hongwei standing beside her. Ma Hongwei showed no emotion at all and just nodded politely.
"I am a weapons researcher?" Zeng Tao pointed at herself, her eyes widened, "Is this true..."
"Well, but your personality is indeed a bit different from before..." Xu Ying looked at Zeng Tao in front of her, and the sense of disobedience in her heart kept rising. "In my impression, you have always been a very emotionally cold little loli. When I saw you for the first time just now, I almost didn't recognize you..."
"Me? Emotionally cold?" Zeng Tao blinked.
"Oh? What about me? What was I like?" Wen Guixin pointed at herself and asked curiously, "What was I like at that time?"
"Uh..." Xu Ying looked at her, Tong Kong trembled for a moment, pursed his lips and said, "It's about the same as you are now, Sister Gui Xin."
"I see..."
“It’s normal to have different personalities.”
Seeing that others were also eager to ask, Xu Xin interrupted at the right time.
"Those people at that time all 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?"
"That's right." Xu Ying nodded. "Each of your tree houses can actually be regarded as an automatic production workshop with time and space capabilities. You only need to input instructions to manufacture equipment."
Everyone nodded.
This statement may sound a bit strange, but it is indeed true.
Since coming to this world and planting the tree house, they have been using the synthesis table, weapon manufacturing table and other workbenches in the tree house to quickly manufacture various tools, furniture, weapons and equipment.
And after unlocking the decoration and functional areas in subsequent activities, functions such as smelting and planting have also been greatly improved.
It’s okay to say that the tree house is a small industrial plant.
"And you survivors are the owners of these 'production workshops' and have the ability to use these 'workshops'. Therefore, other survivors are also very important."
Xu Ying looked at the tree houses outside and the temporary stone houses: "If possible, we need as many survivors as possible, so that our production efficiency will be greatly improved."
Ordinary survivors can also use it.
"Oh, and one more thing. The tree house itself has remarkable abilities. The tree house seeds you planted were developed by us. They were originally designed to provide you with a place to live, but for some reason, you were intercepted by the invaders."
Xu Ying frowned slightly.
"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 the screening is carried out step by step."
Xu Ying's doubts remained unabated.
I don't know what the other party wants to do. Is it just to study mutant humans
She still couldn't fully understand the situation in that world tree.
And in room number 5, there are creepy half-human, half-monster experimental subjects in capsules that fill the walls.
That experiment might even have been conducted without the knowledge of other alien invaders.
This gave her a bad feeling.
Wang Lei at the side asked, "There are two million survivors in this batch, and everyone has tree house seeds. Did you develop them?"
"That's definitely impossible." Xu Ying shook her head. "We should have only sent more than 30,000 people to the future a thousand years later, because there are only so many of us in our team. We originally sent you here just to allow us to reach that era. We can't possibly send so many people to the future."
"So who are the survivors now..." Zhao Xiaochuan asked with a hint of doubt in his tone.
“…It must be the work of alien invaders.” Xu Ying’s eyes darkened.
It must be the work of that monster who traveled through time and space just like her.
That was the one Shi Wanyun saw, the one that was pitch black and covered with eyes, somewhat similar to humans... a half-human, half-monster.
"Didn't you develop the tree house seeds?" Ji Chaoyang asked.
"We developed the tree house seeds, but they were actually developed by the alien invaders themselves." Xu Ying explained, "The tree houses you live in are all mutated forms of banyan trees. You should know this."
That’s right, whether it is the small tree house or the world tree, they are actually banyan trees, and banyan trees are life on earth.
"In fact, the first thing that appeared was not the small tree house you have been living in, but this huge world tree." Xu Ying said as she looked at the endless barren plain outside the window.
The World Tree appears before the Tree House
“The World Tree was originally created by alien invaders using the banyan trees on our planet for numerous genetic modification experiments. It was eventually developed as a tool for colonizing this planet.
They only need to carry a seed to make a huge world tree rise from the ground, thereby controlling an area. It is very convenient.
It has only been a few years since the World Tree was developed, and a large area of the hemisphere has already been occupied and affected by the World Tree. And we, in the seventeenth year of our captivity, moved into the World Tree. "
Glancing at everyone's expressions, she continued, "And the little tree house you have is something we 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."
This news surprised everyone.
It turns out that the World Tree is the original tree house
And it was developed by alien invaders!
"The reason why we were able to develop the tree house before them was simply because they didn't have any demand for this kind of personal tree house at the time." Xu Ying sighed and said helplessly, "For alien invaders, it is not difficult to mass-produce tree house seeds. As long as they want, they can do it."
"So that's how it is..." Xu Xin nodded slowly.
For alien invaders who can develop ordinary banyan trees into giant world trees, it would be very easy for them to mass-produce small tree houses.
It can even be said that this kind of tree house might have been developed long ago when they were making ordinary banyan trees grow bigger and become world trees, but it was not used because it was useless waste.
After all, they are too small, they need big ones.
But now, they seem to be mass-producing the seeds and using them on human survivors.
"Of course, each of the tree house seeds we developed ourselves has been carefully cultivated and tested, so compared to their mass-produced seeds, their functions are much stronger."
Xu Ying patted the wall of the tree house and said, "This tree house is obviously the small tree house we developed. Functionally, under the influence of the World Tree, all restrictions on the functions of the tree house have been removed. Even so, your tree house is still much better than the tree houses of other survivors."
As she spoke, she patted her chest and showed a slightly proud expression: "Our team's products must be top-notch."
"... You mentioned earlier that you were lucky enough to obtain a seed of the World Tree. Could it be this World Tree?" Xu Xin pointed downwards.
"Yes." Xu Ying nodded in agreement, "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 speed of time flow is really far beyond expectations."
At this time, Ji Chaoyang spoke.
"Xu Ying, I want to ask, are the weapons in your hands just... at the level of a thousand years ago? You... should have weapons with higher technology, right?"
This is actually the question Xu Xin has always wanted to ask.
Although the top weapons from thousands of years ago were very powerful for them, they were no match for the alien invaders...
Thousands of years ago, seven billion people on Earth and so many powerful countries were defeated. What can these people do with these weapons
Not to mention that the alien invaders have been developing for another thousand years!
Xu Ying was silent for a few seconds and said, "We can quickly mass-produce the weapons I just mentioned. These weapons, combined with the World Tree and Crystal City, will be enough to protect us and give us time to develop."
"We also have more advanced weapons, which are alien technology weapons that our team developed on the shoulders of alien invaders. But... now is not the time to use them. You don't have the ability, energy and technology to use, manufacture, or even mass-produce those weapons."
As she spoke, her face darkened slightly.
Those weapons are all from another time and space. Once she hands them over, she is likely to...
… There’s no use giving it to them now.
Moreover, at this stage, she is still needed to transfer the technology and talents from below to the upper levels. If she is gone, it will be difficult to deal with.
To be honest, she was relieved that there was a reason not to give away those weapons and technologies.
She doesn't want to die yet.
"So, we need to take the first step first. Yingying, do you want to send the equipment and people up now?" Xu Xin asked.
"Ah... I'm not in such a hurry." Xu Ying looked out the window. "Time flows so fast here, so... we don't have to rush for a day or two, right? We should give priority to developing this place so that we can take over the supporting facilities later."
Xu Ying's eyes were a little evasive at this moment, which could not be seen unless you looked carefully, and her hands were clasped across her chest.
Um…
Looking at her appearance at this moment, Xu Xin raised his eyebrows slightly.
He was very familiar with this girl's appearance.
This is obviously what she looks like when she's lying.
What is being hidden
"Is it really safe here? Our survivors are still a little worried that something might go wrong here." Qi Xuefei suddenly asked.
"Ah, don't worry about that for now." Xu Ying pointed to the roots of the World Tree on the blackboard. "The root system of the World Tree is very developed, deep into the ground for several thousand meters, and can even extend to areas hundreds of kilometers away."
At the same time, she introduced the structure of the World Tree:
"The World Tree matured under the energy supply of the crystal energy core, so the strength of the tree can even reach about 10% of the crystal. Don't underestimate this 10%. You should all know the strength of crystal. Even at 10% of the crystal's strength, there is almost no way to damage it."
"Besides, it doesn't matter if it is damaged. The World Tree can recover by absorbing nutrients and energy from the earth. Not only can it feed back energy to the crystal energy core, but even if the tree is damaged, it can recover quickly. And the recovery speed is so fast that it is invisible to the naked eye."
Finally, she concluded: "So, the World Tree is still very safe. At least I have never heard of the World Tree being destroyed."
