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 them. Therefore, other survivors are also very important."

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

Ordinary survivors can also be of great use.

"Oh, and one more thing: the treehouse itself possesses remarkable abilities. The treehouse seeds you planted were developed by us, specifically to provide you with a place to live, but for some reason, you were intercepted by invaders."

Xu Ying frowned slightly.

"The tree house's abilities are locked. Only through some so-called 'activities' can they be unlocked step by step. Then, a step-by-step screening process will be carried out."

Xu Ying's doubts remained.

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 all over the walls.

That experiment might even have been conducted without the knowledge of other alien invaders.

This gave her a bad feeling.

Wang Lei, standing by, asked, "There are two million survivors in this group, and everyone has tree house seeds. Did you develop these?"

"That's definitely impossible." Xu Ying shook her head. "We should have only sent over 30,000 people a thousand years into the future, because that's how many people we have in our team. We originally sent you here just so we could reach that era. We couldn't possibly send that many people into the future."

"Then who is the survivor 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, and somewhat similar to humans... a half-human, half-monster.

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

"We developed the treehouse seeds, but they were actually based on the alien invaders' own research," Xu Ying explained. "The treehouses you live in are all mutated forms of banyan trees. You should be aware of 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 looked at the endless barren plain outside the window and said.

The World Tree appears before the Tree House?

"The World Tree was originally created by alien invaders using the banyan trees on Earth. After countless genetic modification experiments, they developed it 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.

"Just a few years after the World Tree was developed, a large area of ​​the hemisphere had already been occupied and affected by it. 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 here was developed based on a World Tree seed we were fortunate enough to obtain. It's 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 we were able to develop the tree house before them was simply because they didn't have any demand for this type of personal tree house at the time." Xu Ying sighed and said helplessly, "For alien invaders, mass-producing tree house seeds is not difficult. 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 was probably 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. "This tree house is obviously the small tree house we developed. Functionally speaking, under the influence of the World Tree, all restrictions on tree house functions 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 with a slightly smug expression: "Products produced by our team must be top-notch."
