"You've actually been through so much...!" Wen Guixin whispered in surprise, then said in a slightly dissatisfied voice, "Just let us out earlier! We're so anxious staying in there!"
"That's right!" Zeng Tao said with her hands on her hips, dissatisfied. "What's the point of locking us up in here all this time? And only Wen Xi was released."
"Alright, alright, now's not the time to be talking about this!" Lou Feier whispered, "Look over there! Those giant ships are already heading towards the purple-black light column!"
"Are they really going to take their spaceships and leave?" Qin Fu looked at the four huge ships that were already halfway submerged in the teleportation formation with great interest. "Then maybe we don't even need to take action anymore."
"What's the meaning?"
Wang Lei had been staring at the huge ships in the distance with his eyes wide open, his mouth drooling. It was obvious that he was very fond of those ships. But when he heard Qin Fu say this, he immediately turned to look at him: "Are they leaving the Earth?"
"If we're not leaving Earth, why are we sailing these four warships through space?" Qin Fu shrugged and spread his hands. "Are we just wasting fuel to show off our skills?"
"Forehead……"
Even Xu Xin began to feel a glimmer of hope.
Are these guys really going to leave?
Have they encountered a once-in-a-millennium opportunity?
...No, you can't think like that.
Things can't be so smooth sailing!
Given their current situation, they can't always think about the most optimistic possibilities!
"Anyway, let's get closer and take a look," Xu Xin said to everyone, "Let's observe closely and witness the truth with our own eyes."
Everyone nodded and moved towards the purple-black beam of light.
"Hmm..." Coco turned over in Xu Xin's arms and fell drowsy.
Xu Xin touched the tail of the little guy in his arms, thinking about something.
Coco only falls into this state when there is no danger.
Does this mean that they are not in any danger now?
Unexpectedly, they had just blown up so many factories and even killed an alien invader, but the other side didn't react at all.
It seems that what these four giant ships are going to do is very important.
Everyone walked towards the core location of the alien invaders' base.
The closer you get to the World Tree, the higher the density of the surrounding buildings becomes.
The buildings built by the alien invaders are all made of metal. Of course, this metal is not the meteorite iron buildings they have encountered before, but an alloy melted by a special process.
At least according to Xu Xin's identification ability, the golden light emitted by this material is very dazzling.
Among the grades of items assigned by his identification ability, it seems that the highest grade is gold, but there is a gap between gold grades.
For example, the golden brightness of this alloy is something Xu Xin has never seen before, and it is far inferior to the golden brightness of gold-grade meteorite.
"Yingying, do you know what materials these buildings are made of?" Xu Xin asked Xu Ying who was walking beside him.
"Huh? These buildings?" Xu Ying was a little surprised. "We just blew up so many buildings, and you're just asking now?"
"I want to know, too," Li Wenxi leaned over and asked, "It survived such a violent explosion without a scratch, and Dandan only turned red from the heat... This material is truly strong!"
Everyone else around looked at Xu Ying.
They were all interested in the buildings created by the alien invaders.
"Of course it's strong." Xu Ying explained, "This is meteorite iron alloy, a special alloy with extremely high hardness. Those giant ships..."
Xu Ying pointed at the four giant ships that were already mostly submerged in the purple-black light column and said, "Their main material is this alloy. We tried to research it before, but we found several unfamiliar metals in it, and there's no way to refine it."
"Oh..." Xu Xin understood.
Some are similar to titanium alloys refined by humans.
In comparison, it is much stronger than titanium alloy refined by humans.
"Oh no, doesn't that mean these houses are all made of aerospace-grade materials?" Wang Lei couldn't believe it. "This is simply a waste of resources!"
"That's understandable," Xu Ying said. "After all, this is Earth, known for its 'extremely harsh environment.' They probably wouldn't be able to sleep if they didn't live in a room like this."
Indeed, the waterproof ability of stable metal alloys is unique.
"But it seems that no one lives in there now." Xu Xin walked to the door of a room with a half-open door and looked inside.
The internal structure is very strange to Xu Xin, a human being, so it is inconvenient to explain in detail.
But like the other houses, there were no living creatures in them.
Empty.
"People who can live near the main base should all be in the military, right?" Lou Feier looked at a few rooms, all empty, and said, "I'm afraid they've all boarded those giant ships."
There is such a good thing...?
It always feels like their infiltration was a little too easy.
Because it was too easy, Xu Xin felt a little anxious.
He couldn't help but wonder... Could this be a trap?
"It's not completely devoid of life." Qin Fu suddenly said, "There are several advanced mutant creatures nearby. They're all in a room, and it seems... they're locked up?"
This area is no longer a completely barren desert. Some plants that can grow in the desert can be seen, such as various cacti, prickly pears, and the spiral tree and the caterpillar tree they had seen before.
