Xu Xin and Xu Ying chatted for about five minutes.
"Yingying and I will go up there and will be back soon. You must be careful if you stay here."
The first words Xu Xin said after returning surprised several people.
"What? You really want to go? You want to go too?" Wen Guixin looked confused, "Are you crazy?!"
"Ah?" Zeng Tao had a confused expression.
"It seems that the boss has his own considerations." Qin Fu sat on the ground with his hands behind his back. "You are the ones who should be careful. We are very safe here."
He did not stop Xu Xin and the other man, but it was obvious that he did not want to get involved in this mess.
Li Wenxi grabbed the arms of Xu Xin and Xu Ying, who had walked out of the red mist behind him, and asked, "Are you two serious?"
"Well, don't worry, we're just... going up to get something."
Xu Xin touched Coco's little head in his arms.
"Hmm..."
Only half of Coco's head poked out, and her mouth and nose were in Xu Xin's cloak, so her voice was muffled.
It obviously didn't want to inhale the red mist.
"Get something?" Li Wenxi grabbed him, "Are you really... Then I'll go with you!"
"I'm going too!" Lou Fei'er also came over, "Take me with you!"
"No, it's better for you to stay here." Xu Xin shook his head and rejected them. At the same time, he took off his bracelet and handed it to Li Wenxi. "If there is a problem here, let Zhao Xiaochuan put everyone into the bracelet."
If it was just Zhao Xiaochuan alone, it would be almost impossible for him to be discovered with his abilities, and everyone would be very safe.
Li Wenxi looked at the bracelet in her hand, then looked at Xu Xin.
"Don't worry, with Yingying's teleportation ability, we will be fine." Xu Xin touched her head and said.
"... You should at least explain it in detail!" Li Wenxi grabbed his arm.
She didn't stop Xu Xin's actions, but at least it gave her some idea!
"It's like this, Yingying is now..." Xu Xin thought for a moment and began to explain.
But before he could finish his sentence, Xu Ying suddenly pried open Li Wenxi's hand that was holding Xu Xin's arm.
"Sister-in-law, brother will lend it to me for a while."
Xu Ying smiled at Li Wenxi, and the purple-black vortex under their feet instantly expanded and disappeared in an instant.
Li Wenxi was so shocked that he wanted to catch the two people, but he caught nothing.
Lou Feier dodged and moved past at an extremely fast speed, but still failed to catch the bus.
She knelt on the ground and hammered the spot where the purple-black vortex disappeared, a little annoyed: "What? Why did it suddenly run away? It really took action at the critical moment!"
"They..." Li Wenxi clutched the bracelet in her hand, "Yingying, what on earth are you thinking about..."
"Really going?!" Wen Guixin finally reacted, "What... I might as well control an alien invader to take them up there!"
"I think they are safer this way."
Qin Fu, who was sitting on the ground, fanned the red mist in front of him and said.
"To reach the inner space of the World Tree, we must pass through the hollow area above."
Qin Fu pointed above his head.
"But that area is not safe right now. If you bring a controlled alien invader up there, and they ask you why you came up there, you'll be exposed."
"… That's true, but why did they have to go up there?" Wen Guixin was puzzled. "Isn't our mission going very smoothly?"
"Is it going very smoothly..." Li Wenxi glanced at the scarlet crystal that had been cut into several channels. "Indeed, everything is going according to our plan. Everything is going very smoothly, but..."
Xu Ying gave people a strange feeling just now. Although she pretended to be normal, she was obviously anxious.
Everything was indeed going according to their plan, but if their slightly hasty plan...
Is there a problem in itself
Li Wenxi looked at the bracelet in her hand.
"I hope none of us will be in danger..."
…
The siblings Xu Xin and Xu Ying have arrived at the hollow area in the trunk of the World Tree above.
The moment he saw the situation here, Xu Xin immediately held his breath.
Lots of alien invaders!
Hundreds of alien invaders and tens of thousands of eyes are densely distributed in various locations in this space.
There are also many machines that look strange, but you can tell at a glance that they are weapons!
The entire space, illuminated by the scarlet glow of the World Tree's core, looked like a bloodthirsty battlefield!
I don’t know how the monster made the situation become like this.
The location where Xu Xin and Xu Ying appeared was the farthest from the core of the World Tree.
Because according to their speculation, the light from the core of the World Tree would reduce the effectiveness of their Invisible Cloaks, so the two could not get too close to the core of the World Tree.
Xu Xin glanced at Xu Ying, who was silently observing the surroundings beside him, and sighed in his heart.
Just now, Xu Ying told him that their plan...
Something went wrong.
"I'm afraid our nuclear weapons cannot completely destroy the Scarlet Crystal."
She observed the Scarlet Crystal for a long time during this period and discovered a fact.
That is, the various physical properties of this concentrated scarlet crystal are extremely similar to the white crystal on their earth.
The laser core temperature of the cutter reaches hundreds of millions of degrees, which is why it is able to cut the scarlet crystal. Other tools and weapons cannot even scratch it.
Extremely high hardness and a melting point of over 100 million degrees.
She was very familiar with this physical property. It took them several years to build the crystal city.
The processing equipment they used to build Crystal City was as big as a mountain, and it also adopted the technology of alien invaders.
It is unclear what happened to the device later. Perhaps it was destroyed. After all, it could threaten Crystal City.
As someone who had participated in the construction of Crystal City, she knew very well that Crystal City could not be destroyed by human technology alone, even nuclear weapons.
If it exploded at a very close distance, the most that could happen was that the scarlet crystal would be blown into multiple pieces and scattered everywhere, but if you wanted to completely destroy it...
All I can say is that using only nuclear weapons is extremely difficult, almost impossible.
However, the weapons she brought from another time and space can make up for this shortcoming.
As long as their nuclear weapons can blow up these scarlet crystal blocks, the weapons she brought from another world can clean up the mess.
"Let's wait here." Xu Ying pulled Xu Xin to the edge.
"Hmm." Coco nestled in Xu Xin's arms, looking towards a place not far from here.
The place where Coco was looking was also the edge of this hollow area, less than twenty meters away from the two of them.
There, there are three vine ball elevators.
At this time, they are all closed and completely wrapped by vines.
"If there are alien invaders coming in later, we will follow them in." Xu Ying whispered.
"Yingying, I have a question about your guess." Xu Xin whispered.
"Hmm? What's the problem?"
"If this concentrated scarlet crystal is so hard and strong, how can the alien invaders use it as a source of life?"
According to the monster, this scarlet crystal is edible.
It’s so hard, how can you eat it
"Just swallow it." Xu Ying pursed her lips. "Why do you think they cut these scarlet crystals into small pieces the size of a fingernail?"
"…So the alien invaders were able to digest small pieces of concentrated scarlet crystal?"
"This scarlet crystal itself is the 'food' of their species. Concentrated scarlet crystal is probably like... compressed biscuits?" Xu Ying guessed.
Compressed biscuits...
"The alien invader's 'stomach acid' is really strong..."
"It's not that they are powerful. It's probably just that the small pieces of scarlet crystal the size of a fingernail are too small and contain too little energy. They have lost some of the properties of the large pieces of scarlet crystal." Xu Ying speculated.
"Does the earth's white crystal also have this property?" Xu Xin asked.
"I don't know about that." Xu Ying shook her head. "We never cut such small and fragmented white crystals before. This is just a guess."
Xu Ying's speculation is not without reason.
The fist-sized pieces of concentrated scarlet crystal they had obtained earlier could drive alien invaders crazy.
But the fingernail-sized ones won’t.
"So, we have to... use the weapons you brought." Xu Xin's voice sank slightly.
If that is the case...
He looked at Xu Ying.
If this is true, Yingying only has a few hours left.
What do people usually do in the last few hours of their life
Xu Ying's choice is...
"I'm just struggling a little longer..." Xu Ying bit her lip and said.
Her choice was to struggle a little longer.
During the few hours she spent in the red fog of the underground space, she kept thinking about this matter.
But because she was afraid of dangerous situations, she kept waiting below.
But the more she waited, the more panic she felt.
There is a feeling... that life is slipping away bit by bit and meaninglessly.
Moreover, there has been no danger below during these few hours.
Finally, after seeing Zhao Xiaochuan complete his excavation, Xu Ying could no longer sit still.
She decided to make one last effort.
She really doesn't want to die yet.
Given her current unstable condition, if she used weapons from another time and space, she would basically be wiped out of the world like her predecessors.
At least... I want to see what the world looks like after the alien invaders are driven away before I die.
This is also the wish that her brother, Xu Xin from another time and space, has placed on her.
So, she decided to sneak into the interior of the World Tree and look for weapons hidden by the alien invaders.
If it could have the same effect as the weapon she brought from another time and space, then she wouldn't have been wiped out of the world.
Xu Xin finally decided to come with her.
He has the ability to identify and directly check some valuable materials, and he also has a little creature in his arms who somehow knows some key information.
If we need to find some key weapons, it will be much easier if he comes along.
but…
Xu Xin glanced at Xu Ying who was already sitting on the ground with her legs hugged.
He didn't want to attack Xu Ying, but he thought that this world tree should contain the weapon she wanted.
Especially the residential area above.
I'm afraid it's strictly prohibited to carry weapons there.
How could it be possible to place some super powerful weapons
Xu Xin looked around: "These weapons, aren't they okay?"
There were strange weapons and equipment parked all around, ready for action.
At the same time, there were tens of thousands of eyes blinking in all directions like waves.
Fortunately, Xu Xin and his team were not discovered.
"No." Xu Ying shook her head. "I have seen these weapons. They are useless against the white crystal, and they should also be useless against the concentrated scarlet crystal below."
"So what kind of weapon are you talking about?" Xu Xin asked.
"... a weapon that can directly tear open a rift in space and time through an explosion." Xu Ying whispered.
Tearing open a rift in time and space
It sounds strong, but it seems...
That’s all
"Like when you teleport?" Xu Xin asked.
Didn’t Xu Ying teleport through the space-time rift
His coordinates can create rifts in space and time.
Isn’t that the purple-black vortex
Space-time rifts seemed to be very common things to him.
"no the same."
Xu Ying shook her head.
"The space-time channel I used to teleport was created using space-time abilities. The space-time rift created by the explosion was created entirely by the power of the weapon to distort space and time, creating something similar to a black hole."
Creating a black hole…?!
"... You actually have such a powerful weapon..." Xu Xin was really shocked.
"... Actually, it's not that powerful." Xu Ying rubbed her hair in annoyance. "This weapon looks powerful, but the actual power is so strong that the explosion area that can tear the space apart is only the core area, which is about two meters in range. The area is about the same as a nuclear weapon."
"Then... how are we going to clean up the mess with this kind of weapon?" Xu Xin asked.
"After we use nuclear weapons to blast this huge scarlet crystal into relatively small pieces, this weapon can be used."
Xu Ying thought about it and explained.
"Although the edge power is not great, the core power is strong enough to create a space-time rift. The attraction of the space-time rift is very strong, and it will suck the scarlet crystals that have been blown into small pieces into it, and send those scarlet crystals directly into the extremely chaotic space-time rift."
… It’s actually possible.
Xu Ying continued, "If one is not enough, then use two, or three. We can always sweep away all those scarlet crystals and send them all into the chaotic space and time, never to see the light of day again."
Having said this, she paused.
She suddenly thought of the giant tentacle beast in the teleportation formation that dragged the alien invaders' giant ship into it.
... Could it be that those giant ships have already... entered the chaotic space-time
Are most of the alien invaders' forces... destroyed
Of course, this thought only lasted for a moment before she rejected it.
There is no such good thing.
Ji Chaoyang also said that according to his prediction, the World Tree would be completely conquered the next morning.
If the main force of the alien invaders was destroyed, how could the World Tree be breached
Why…
Xu Ying sighed.
She felt that her final struggle was meaningless.
But she couldn't just sit there doing nothing in the red mist below.
Fortunately, her brother is with her.
At this time, Xu Xin spoke up: "Yingying, if that's the case, if you want to find this powerful weapon, I think we shouldn't look for it in this world tree, but outside the world tree, in the city around the purple-black light column. That's where the army is stationed."
Moreover, in his opinion, the important weapons should be in the four giant ships that have already left. How could they be placed in the living area of the World Tree
At this moment, an alien invader moved towards the vine elevator.
"The opportunity has come, let's go up and take a look first." Xu Ying glanced at the little guy in Xu Xin's arms, "Didn't this little guy want us to go up and take a look?"
"嘤!" Coco immediately poked out her little head and waved her paws.
That’s right, just now when Xu Xin and Xu Ying were talking in the red mist, the little girl Coco suggested that they go up there.
It seems like there's something good up there.
But if it’s not what Xu Ying needs… I don’t know.
"Then let's go up and take a look first."
Xu Xin and Xu Ying followed the alien invader and mixed into the vine elevator.
