Starting Off Survival With A Small Treehouse

The entire prison was empty.

"Let's go down and have a look."

Xu Xin immediately walked down the spiral staircase that he had walked last time.

Xu Ying and Li Wenxi were both here for the first time, and they didn't know what to do. They could only follow Xu Xin and continue walking down.

"Brother, in this underground prison, except for us... there is no reaction from other life." Xu Ying looked at the cells on both sides of the stairs and said.

"Go down and have a look."

The three of them soon reached the lower level of the prison.

Along the way, all the prisons were empty.

"My God... even gold-grade meteorite iron is used here..." Xu Ying exclaimed as she walked, "This entire underground prison is too luxurious..."

"Is meteorite a very rare thing?" Li Wenxi reached out and grabbed the prison railing, feeling the texture of this special metal.

"Very rare!" Xu Ying nodded fiercely, "Exceptionally rare, how should I put it... The status of meteorite iron in alien technology is equivalent to titanium alloys and beryllium alloys in our earth's technology."

"...Aerospace technology?" Xu Xin looked back at Xu Ying.

"Yes. At least 60% of the total weight of the alien invader's spaceship comes from meteorite. Gold-grade meteorite."

Xu Ying nodded and patted the metal wall of the underground prison: "This gold-grade meteorite is the highest quality meteorite. Meteorite is a special metal resource, not an alloy, but directly mined and smelted. Both mining and smelting are extremely difficult. I never expected that there would be an underground prison made entirely of meteorite iron."

"Is it difficult to smelt? My furnace can smelt it." Li Wenxi grabbed the metal railing of a prison and looked inside. She didn't find anything. She turned back somewhat bored and said, "Before I left with you, I had already Several pieces of meteorite have been smelted, but for now we can only smelt purple grade ones."

"It is indeed difficult. At least among us humans, only your technology can smelt meteorite, sister-in-law." Xu Ying said with an innocent expression, "Besides, it took you nearly three hundred years to smelt meteorite." , it was only in the last few years before the collapse of that world that they developed a method of smelting meteorite. Ah, I mean my sister-in-law."

"That sister-in-law..." Li Wenxi pursed her lips, "It sounds weird. It's really difficult. Then...after finally figuring out how to smelt meteorite, didn't you guys make more?"

"Yes. Of course there is. Most of our special weapons that I will hand over to you in the future are made of meteorite, but the quantity is... somewhat small and cannot be equipped for many people."

Saying that, Xu Ying sighed: "That's why we didn't give up on mass-produced earth weapons and built arsenals in the underground world. It's a pity that something like that happened down there..."

Xu Xin glanced at her.

Speaking of which, Xu Ying seemed to have said the last time she met him that the underground world might have been secretly eroded by alien invaders.

After they came up, they were never asked what happened after that.

Forget it, let’s ask again later. Let’s find out the situation here first.

However, now they have reached the bottom of the prison. The entire prison is indeed as Xu Ying said, empty and empty.

There wasn't even a hair on it and it was so clean that Xu Xin couldn't help but wonder if those guys had carried out a general cleaning and taken away all the garbage after evacuating from here.

This is too clean.

So civilized?

"Why are there no mass production of meteorite weapons?" Li Wenxi was a little confused. "Judging from the speed at which I smelt meteorite, although it is not fast, if it is on a large scale, there should be no problem in mass-producing meteorite, right?"

What she means is that although the refining speed of one furnace is very slow, as long as hundreds or even thousands of furnaces work together, the overall smelting speed can achieve a qualitative leap.

"It can't be that easy." Xu Ying rubbed her hair with some distress, "We were in a situation where it was not easy to build a large-scale factory, and the most important thing is... the meteorite ore is too It’s scarce. This metal doesn’t exist on earth at all. It was all brought by those alien invaders.”

"After they later took root on the earth, there was a serious shortage of this metal. In order to get rid of it once and for all, they did not know what method they used to attract asteroids with sufficient meteorites to hit the earth many times. After that, we learned about this metal, Call it 'meteorite'."

This is how the name of meteorite comes from.

but……

Guide an asteroid to hit the Earth? !

Xu Xin and Li Wenxi both looked at Xu Ying with dumbfounded expressions.

Seeing the expressions of the two people, Xu Ying was stunned for a moment, and then she knew what they were thinking, and burst out laughing: "Hey, you won't hear the asteroid hitting the earth, I think it must be very powerful, right?" ?”

"Ah... isn't it?" Li Wenxi blinked, "Asteroid hits the earth!"

"Uh..." Xu Xin also had this idea.

According to research, many mass extinctions of species on the earth were caused by asteroids hitting the earth.

The large dinosaurs that had dominated the earth for hundreds of millions of years also became extinct because of this.

Therefore, when he heard this term and heard that alien invaders could control asteroids to hit the earth, it was strange that he was not surprised.

"Of course not. It is actually very common for asteroids to hit the earth, much more frequently than you think."

Xu Ying raised the corners of her mouth and explained.

"It's very common. Even on the Earth where we lived thousands of years ago, asteroids hit the Earth every year. But the size of the asteroids in these asteroid belts were not very big at all. Some were even only a few meters in diameter. , it’s just a big rock.”

"...Huh? Is that also called a planet?" Li Wenxi said a little speechlessly.

"The big rocks in the asteroid belt are all planets. You have all seen meteors, they are similar things. However, most of the meteors are completely consumed when they pass through the atmosphere at high speed, and a small part is not consumed. After it falls to the ground, it is called a meteorite."

"I understand." Xu Xin asked immediately, "How big are the meteorites that the alien invaders can control?"

"It's not that big. After being consumed by the atmosphere, the overall size when it falls on the ground is only a few hundred meters in diameter at most."

Xu Ying nodded her lips and thought for a while.

Then she waved her hand: "The meteorite that caused the extinction of the dinosaurs was more than ten kilometers in diameter and created a crater with a diameter of three hundred kilometers. This is not of the same magnitude at all."

"...A meteorite hundreds of meters in size can easily destroy us..." Li Wenxi panicked slightly, "It's still so strong..."

"You said they guided meteorites to attack us? Impossible." Xu Ying said with a smile, "It is also very difficult for them to guide meteorites. If it were not for the purpose of taking back the unowned flowing resources in the universe, they would I wouldn’t do that.”

"If an asteroid with a diameter of several hundred meters hits the earth, can the range of damage caused by it be tens of kilometers? And they can't accurately guide the position, so it's better to use nuclear technology directly. Earth's technology can do better. Ten thousand people will laugh when they see this power."

Xu Ying spread her hands.

That being said, that's true.

Although the power of guiding meteorite attacks is considerable, it is really thankless.

"But, so there are already meteorites on the earth?" Xu Xin asked.

"Well... there is, but it is under the complete control of the other party. We really don't have the ability to obtain it." Xu Ying sighed, "It's difficult without resources."

"We still have some meteorite ore," Xu Xin said. "We got it from here, in the underground space below."

"Then let's go down and take a look."

Using the same method they used to get down, the three of them arrived at the underground warehouse.

The huge warehouse below was still empty.

There used to be some shelves, but now there is nothing.

Completely evacuated.

"What exactly is going on?"

Xu Xin frowned.

The place is completely empty.

"They couldn't have evacuated after your last 'underground world exploration activity', right?" Li Wenxi speculated, looking at the empty underground warehouse.

Xu Xin shook his head slowly: "No, no, after the World Tree matured, Lou Feier and I came down once. At that time, there were groups of petrified creatures trying to attack us."

At least then, it couldn't be empty.

Later, he and Ji Chaoyang came down again. Soon, they went out to explain the situation, and only ten minutes passed outside.

It's only been ten minutes outside, but it's been almost a day inside.

When he and Ji Chaoyang came down that time, there were no petrified creatures attacking them, and they were completely invisible.

Then, after the two went out, the explorers discussed and brought all the survivors inside the World Tree.

Xu Xin slept outside for three and a half hours, causing time to flow inside the World Tree for half a month.

...and the time in this underground world also flowed for half a month.

In other words, this prison should have been emptied during this period!

Why……?

Is it because the weird time flow here scares them?

Because they know this is under the mature enemy World Tree, so they don't dare to stay?

"Although I don't know why they left, isn't this a good thing?" Xu Ying grabbed their wrists again, "At least we don't have to drive them away ourselves."

At the same time, the three people were teleported into the prison passage again.

Xu Xin brought the two women to the control room.

"...Is this place empty too?"

The control room, which was originally filled with complex mechanical consoles, was now empty.

Following the narrow passage they walked through before, the three of them walked out of the prison and into the space outside the prison.

That is, the space with the soft giant beast as the ground.

But...it was pitch black.

Originally there was lighting on the top here, but it's gone now.

However, all three of them had eaten red berries and had night vision, so they could still see clearly around them.

"Down there, it's empty...?"

On the lowest level of the underground prison, the soft giant beast that was originally "suppressed" under the prison has disappeared.

There is no support below the underground prison, and it is suspended directly in the air, equivalent to hanging on the main vine bundle outside.

Underneath the underground prison, there is a giant pit more than 100 meters deep.

"Wow..." Li Wenxi looked down and her eyes widened, "It's so deep down there!"

"Be careful!" Xu Xin pulled her up. "The ground near here is very slippery."

Xu Ying stared at the giant pit below: "Isn't that the soft giant beast below? Alas, I came a step too late and let it run away..."

Regret was written all over her face.

"Who is that big guy?" Xu Xin looked at her and asked, "I used my mind-reading ability to read its voice. It knew me. We were able to escape thanks to its help. .”

"It's a very strong giant beast trained by my brother. Ah, I'm not talking about you, it's that brother."

Xu Ying pointed to the sky and said.

"...No need to explain." Xu Xin was speechless.

"Oh. I actually don't know much about it. I only know that it is a giant beast that is genetically mutated from insects. It has extremely strong defense power. Its soft and flexible body can resolve almost all attacks. It can also directly rely on Its body surface devours those who attack it."

What a giant insect.

Thinking about the behavior of the giant insect devouring the giant beast before, it was indeed what Xu Ying said.

"Moreover, the most important thing is that this giant insect has super strong reproductive ability. If the firepower is fully turned on, tens of millions of eggs can be laid every few days, and they will hatch quickly. The size is the same as those giant insects in the underground world. Pretty much." Xu Ying continued to explain.

"Insect race, or insect mother?" Xu Xin suddenly realized.

"Well, I also called it the insect mother before."

Xu Ying nodded.

"Because the genes of the insect mother itself are relatively chaotic, the traits of the insects hatched from the eggs they lay will also be very different. They can fly in the sky, crawl on the ground, or burrow into the ground. I even suspect that the giant insects in the underground world may be A lot of it is its descendants."

Even the giant insects in the underground world are related to this insect mother!

Xu Xin took a deep breath and looked at the empty pit below, and suddenly felt heartache.

"It would have been nice if it hadn't left..."

The giant insect helped him at that time and was obviously on his side.

If only it could be collected...

"The endless army of insects." Li Wenxi imagined it, "It also has super defense power and can protect the World Tree... Oh my god, what did we miss!"

"Sigh..." Compared with just now, Xu Ying was already in a depressed mood, looking at the huge pit below in a daze: "I thought I could harvest this insect mother this time... but it turned out that I was overthinking it."

She looked back at the suspended pillar-shaped prison.

"I was thinking before, what can suppress the insect mother. It turns out that it is the 'Dinghai Shenzhen' made of meteorite iron. This is the only thing that can suppress the insect mother... Well, now I can only hope that the insect mother is If he ran away, he would have been caught by alien invaders, otherwise he would have..."

Insect mother...?

I didn't expect that there was such a giant beast.

"Probably he won't be caught." Xu Xin speculated, also trying to comfort himself, "If he could be captured, I'm afraid he would have been captured long ago, and he wouldn't have spent so much effort suppressing it here."

correct!

At that time, the insect mother let out a powerful infrasonic roar, which made everyone feel chest tight, short of breath, dizzy and dizzy.

At that time, Xu Xin did not have the ability to read minds, so it was Coco who translated for him.

What it meant at that time was, don't tease it anymore, otherwise, it will perish together with this place.

And the regulators here are obviously afraid of it.

Thinking about it this way, the other party should really not have the ability to subdue it and take it away.

Xu Xin breathed a sigh of relief.

"Now that we basically understand the situation in the underground world, let's go up first and discuss the situation here together. Oh, by the way." Xu Xin looked at Xu Ying, "We should be able to divide the authority, right?"

"Of course. Well, let's go back first." Xu Ying grabbed their wrists.

"Ah? Wait a minute, why don't you take a look at the mineral resources here first?" Li Wenxi was a little itchy about the mineral resources in this underground world.

"Go up first, and then you can bring more people down to investigate."

"Oh, that's fine."
