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?"

?”

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

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

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

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

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

Is it so civilized?

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 entirely made of meteorite iron."

Originally there was lighting on the top here, but it is no longer there.

"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 or crawl on the ground. I even suspect that the giant insects in the underground world may be

A large part of them are its descendants."

What a giant insect.

"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... Alas, 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..."

The huge warehouse below was still empty.

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

"It is indeed very 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.

, 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."

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

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

"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."

"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.”

"...Is this place empty too?"

"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 enemies that attack it."

Xu Ying spread her hands.

At that time, the giant insect helped him, and he was obviously on his side.

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

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

"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 in terms of quantity... they are a little small and cannot be equipped for many people."

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

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

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

And the regulators here are obviously very afraid of it.

Why……?

Is it because the weird time flow here scares them?

Xu Xin breathed a sigh of relief.

However, all three of them have eaten red berries and have acquired night vision, so they can still see clearly around them.

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

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

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

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

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

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

Xu Ying nodded her lips and thought for a while.

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

"Why are there no mass production of meteorite weapons?" Li Wenxi was a little puzzled. "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?"

"It's not 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 large

It’s scarce. This kind of metal doesn’t exist on earth at all. It was all brought by alien invaders.”

"Moreover, the most important thing is that this giant insect has super 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.

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

Xu Xin glanced at her.

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

"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."
