Wen Guixin and others who have already entered the World Tree are still advancing in the trunk.
“Why hasn’t it arrived yet…” Wang Lei looked behind him from time to time.
Behind them, the road they were walking on was growing forward all the time, at a speed basically the same as the speed at which the alien invaders were dissolving the trees of the World Tree.
Their passage has always been maintained at a length of about five meters.
Wang Lei was always afraid that the healing speed of the World Tree behind him would speed up and squeeze them to death.
"Don't be so scared. Even if we can't get in, we won't die." Xu Ying couldn't help but roll her eyes. "I'm here, what are you afraid of?"
“That’s true…” Wang Lei touched his head embarrassedly.
"Speaking of which..." Qin Fu was standing at the back, occasionally reaching out to touch the wall that was growing and healing. "The World Tree heals very quickly. Even if we attack the World Tree with nuclear weapons, our naked eyes will not be able to detect the damage to the World Tree because it will heal in an instant. Is that what you said?"
Qin Fu looked at Xu Ying.
"That's right." Xu Ying nodded, "But this is information from that time and space. That time and space was only three hundred years after the war, and now it's a thousand years after the war. It's normal for there to be some changes."
As she spoke, she looked at the "Slime" alien invader in front of her. At this time, Wen Guixin was touching this thin alien invader that was stuck to the wall and corroding forward.
Because she was afraid that something might happen to the alien invader at this critical moment, she had been controlling her toxins to deeply corrode the alien invader, preventing the alien invader from regaining any consciousness, otherwise all her efforts would be wasted.
"The alien invaders have now invented a potion that can make the World Tree wither. Isn't it normal to slow down the World Tree's self-healing ability? What are you afraid of?" Zeng Tao said indifferently.
Although she said so, she was the person closest to Xu Ying at this moment, and her whole body was almost pressed against her.
It keeps growing from behind, it's really scary!
She was afraid that the water behind her would suddenly surge. If that happened, she was closest to Xu Ying, so at least she wouldn't be left behind.
If I were to be wrapped by the trunk of the wildly growing World Tree...
Zeng Tao shuddered slightly.
Woohoo... So scary, if I had known earlier I should have been with Xu Xin and the others...
"How far do we have to walk..." Wen Guixin already had a layer of fine beads of sweat on her forehead.
She had to keep infecting a target and ensure that the target did not die from excessive infection. This kind of precise operation was too difficult for her.
She was really walking on thin ice now, fearing that she would accidentally kill this slime alien invader.
"It should be almost there." Zhao Xiaochuan looked back and said, "According to my estimation, we should be very close to the core area of the World Tree's trunk now."
"The core area of the World Tree's trunk?" Wen Guixin perked up. "Isn't the World Tree just a large tree house? You should remember that the trunk of the tree house is hollow, right?"
"Of course I remember." Zeng Tao answered quickly, "Not only is it hollow, but there is also a part of the tree house core buried underground in the soil in the hollow tree trunk. Didn't we dig the tree house core from the hollow tree trunk... Huh?"
Zeng Tao's eyes suddenly widened: "If we continue forward and enter the hollow area of the World Tree's trunk, wouldn't it be possible... to see the core of the World Tree?"
Everyone was cheered up.
"We have to get there first..." Wen Guixin had already clenched her teeth, "Hurry up... Hurry up! Hurry up!"
She felt like she was losing control of the toxins she was injecting into the alien invader's body.
If these toxins were allowed to explode instantly, the alien invaders would probably die instantly.
Although they will not be trapped here, their plans will be completely disrupted, which means all their previous efforts will be wasted.
She didn't want their plan to fail because she didn't have good control over her own abilities!
Wen Guixin's erosion of the alien invaders continues, and the alien invaders' dissolution of the trunk of the World Tree also continues.
But no matter how Wen Guixin urged it, it still dissolved forward at such a fast speed. This was probably its fastest speed.
"Sister Guixin, you..." Xu Ying also noticed that Wen Guixin's expression was a little forced at this time, and her face changed.
But she couldn't help much and could only pray that Wen Guixin could hold on.
In front of them, the alien invaders were dissolving forward, and behind them, the trunk of the World Tree was constantly growing and healing. They were like pests moving through the tree trunks, gnawing at them and moving forward step by step.
One meter, two meters.
Ten meters, twenty meters...
Finally, with a belated "click" sound, the wall to which the slime-like alien invader was attached suddenly and slowly tilted forward.
As the wall collapsed, light filtered in through the gaps created.
Scarlet.
With a loud "bang", the wall where the alien invaders were attached collapsed forward, hit the ground, and broke into pieces!
The alien invader that was originally attached to the wall as a thin piece bounced up at the moment the wall fell and shattered into pieces, and returned to its previous shape of a piece of slime.
At the same time, all its eyes that had been closed before opened, but its look was very dull, and all its eyes stared motionlessly in the direction of the glasses.
It was obvious that this alien invader was unconscious.
“We’re finally here…!” Wen Guixin’s legs went weak and she almost fell to the ground.
This kind of delicate operation is really not suitable for her...
I'm so tired. I feel like all my brain cells are exhausted and I'm mentally exhausted.
However, her attention was soon drawn to what was in front of her, and she slowly opened her eyes.
Not only her, but everyone present was shocked.
"Is this... the core of the World Tree?" Wang Lei muttered to himself.
That’s right, what appeared before everyone’s eyes at this moment was an extremely huge spherical crystal that was half buried in the soil.
Because only half of it was exposed outside the soil, everyone could only see half of the crystal ball.
Although it was only half a crystal ball, the height of the crystal ball reached nearly twenty meters.
This is a huge crystal ball with a diameter of nearly forty meters!
Of course, the core of the World Tree itself should be extremely huge, and everyone is mentally prepared for this.
But they didn't expect that the core of this world tree did not emit a bright white light like their world tree.
The core of this world tree is actually a scarlet crystal!
This scarlet crystal emits a scarlet light, illuminating the entire hollow area of the World Tree blood red.
Xu Ying raised her head and looked upward.
This is indeed the hollow area of the World Tree's trunk.
The world tree here is not the world tree over there whose internal space has expanded a hundred times, so if you look up, you can see the dome of this space.
This space is about a hundred meters high, which is exactly the height of the tree trunks below the canopy.
"Ah!" Suddenly, Wen Guixin shouted anxiously, "Don't die!"
Everyone shifted their gaze away from the huge scarlet crystal in front of them and looked at Wen Guixin, or rather, at the alien invader she controlled.
At this time, Wen Guixin had already put her hand on the "Slime" again.
Even though the eyes of this slime were open all over its body, and she pressed directly on its eyes, she didn't care at all. Instead, her face looked anxious and ugly.
"how… "
Before Wang Lei finished asking the question, everyone saw that the alien invader under Wen Guixin's command began to dry up.
The originally relatively round body of the "Slime" began to shrink rapidly, and the speed of shrinking was unusually fast, just like a punctured balloon, and in just a few seconds it turned into a piece of skin on the ground.
"I..." Wen Guixin stared at the skin blankly.
She tried to step on it with her foot, and the skin shattered directly like a layer of dry seaweed.
"This..." She slowly raised her head and looked at everyone, wanting to cry but having no tears, and feeling a little helpless.
The alien invader she controlled finally couldn't withstand the toxins she repeatedly injected into its body and died.
"Wow... This is too extreme!" Zeng Tao squatted down and poked the dry fragments on the ground with her fingers. "If we die sooner, we won't be able to get in!"
The rest of the people looked at each other again.
They were clearly waiting for it to take them to the underground space, but it ended up dying...
So what should they do now
"This...what should we do now?" Wang Lei said somewhat helplessly.
This isn't even the inside of the World Tree's crown, but just the hollow area of the World Tree's trunk!
Qin Fu was not panicked, and said calmly: "Don't worry, since this slime brought us here, it means there must be a passage up or down here, just look for it."
That’s true.
Everyone looked around.
"Anyway, let's explore the surroundings first." Xu Ying said.
That's all we can do.
"I'm sorry." Wen Guixin felt a little guilty, "If only I had a little more control..."
"Oh, what are you saying sorry for?" Wang Lei waved his hand. "If it weren't for you, we wouldn't be able to get in. Let's take a quick look around."
"Too."
At this moment, Xu Ying's attention was all focused on the most conspicuous thing in the hollow area of the tree trunk - the huge scarlet crystal located in the center of the entire area.
The eyes of others were also focused on this huge crystal hemisphere.
"Is this the core of the World Tree?" Zhao Xiaochuan exclaimed, and at the same time he was a little excited, "Why is the core of the World Tree red? Could this be the 'source of life' of the alien invaders we are looking for?"
"No way." Qin Fu looked at the scarlet crystal. "We all know that the red light emitted by the source of life is very strong, so strong that even a small piece of it can make people uncomfortable. Didn't we steal a lot of it from those factories?"
Xu Ying touched the backpack she had been carrying with her on this trip.
She and Xu Xin each took a portion, and now there were more than a dozen small pieces of scarlet crystal in her backpack.
"But the light emitted by this crystal is very soft. To be honest, it feels quite comfortable when it shines on my body." Qin Fu shrugged, "So, this can't be what we are looking for."
That's true.
No matter how you look at it, this crystal doesn't look like the target they are looking for.
"But, this is the core of the World Tree, right?" Zeng Tao asked doubtfully, "Isn't the World Tree created using the white crystals of the Earth? Why is the core of this World Tree scarlet?"
"This is their base camp." Wang Lei thought this was easy to explain. "Isn't it normal for their base camp to be a little special? Maybe the genes of this world tree have mutated?"
"Are you kidding me..." Qin Fu was speechless, "This is scarlet crystal..."
"What is going on..." Xu Ying also thought of the problem at this time.
She felt her heart tighten.
What is Scarlet Crystal
It is the source of life for alien invaders!
They knew before that the process of using white crystal to transform scarlet crystal was extremely complicated and could not be achieved on Earth at all. They had to send the white crystal back to the mother planet.
That is why the concentrated scarlet crystal is so precious.
Their plan was based on this. If the concentrated scarlet crystal was destroyed, the alien invaders would lose their source of life and flee in panic.
But the huge, non-condensed scarlet crystal in front of them suddenly appeared, as if mocking their plans.
If the alien invaders can already create scarlet crystals on Earth, then their plan will be useless!
"I say, can we go home now?" Qin Fu looked at the giant scarlet crystal and felt that he had lost his motivation.
He also thought of the meaning of this huge scarlet crystal.
"... No, this is impossible." Xu Ying walked towards the scarlet crystal.
It should be impossible for alien invaders to refine scarlet crystal on Earth.
There's something wrong with this giant scarlet crystal!
The closer she got, the more she felt something was wrong.
The closer she got, the more comfortable she felt, and she even felt her mind relax.
This is the characteristic of white crystal.
She walked over to the huge crystal and reached out to touch it.
“… This is not a scarlet crystal.” Her frown slowly relaxed and she let out a long breath. “This is the normal World Tree Core, a white crystal.”
"White crystal?" Zeng Tao raised her head and looked at the entire crystal. "But it's red?"
Xu Ying was also a little puzzled by this.
The properties it exhibits are clearly those of white crystal, so why does it appear the color of scarlet crystal
A little weird...
Um
Xu Ying thought of a possibility.
Her eyes slowly opened wide.
"Ah, I get it!" She clapped her hands, looked up at the huge crystal in front of her, and gradually backed away.
As she retreated, gradually, the full picture of the core of the World Tree appeared in her field of vision.
After seeing the crystal clearly again, her eyes became brighter: "I know what's going on!"
"Ah? What's going on? Isn't this really scarlet crystal?" Wen Guixin asked.
"No, of course not." Xu Ying smiled, "However, this scarlet light does have something to do with our goal."
The other people were puzzled.
What's the meaning
"Think about it, where in our world tree can we see the core of our world tree?" Xu Ying reminded.
"Where... the underground space?" Zeng Tao replied.
In their world tree, in the underground space, which is the control area where Ji Chaoyang and his team are now, they can see the core of the world tree.
The underground space is an area surrounded by the roots of the World Tree, and directly above the entire area, a part of the core of the World Tree is exposed.
The reason why that area is so bright is because of the light released by the core of the World Tree that is exposed in the dome.
The upper part of the core of the World Tree, like the core of the tree house, is above the ground, which is the part that Xu Ying and the others are seeing now.
In this way, the location of the core of the World Tree can be determined.
Below the core is an underground space, and the lower half of the core is exposed in the underground space. The upper half of the core is exposed in the hollow area in the center of the World Tree's trunk.
That is the area where they are now.
To put it simply, the core of the World Tree is stuck in the ground, with an underground space below and a hollow area in the trunk above.
"Oh..." Qin Fu suddenly realized, "So that's how it is."
"What?" Zeng Tao turned to look at him, with a look of curiosity, "Why is it like this?"
"Think about it, where is the target we are looking for now?" Qin Fu asked.
"Are you talking about the scarlet crystal? Isn't it in the underground space?" Zeng Tao pointed downwards.
"Oh!" Wen Guixin also understood, and showed the same surprised expression, "I understand too..."
"What? How do you all understand?" Zeng Tao looked confused.
"I don't understand everything. At least I don't understand." Zhao Xiaochuan pointed at his nose.
"I don't understand either." Wang Lei scratched his head.
Xu Ying explained it to them.
The reason is actually very simple.
As mentioned just now, below the core of the World Tree is an underground space, and the scarlet crystal that emits an extremely dazzling scarlet light is located in the underground space of the World Tree.
The light emitted by the scarlet crystal penetrated the core of the World Tree in the dome of the underground space in reverse, illuminating the entire core of the World Tree into blood red.
The core of the World Tree was like a lens, allowing the light from the scarlet crystal underground to pass through it to the ground and to where Xu Ying and the others were currently.
So, they saw a world tree core that seemed to emit scarlet light but was actually very normal.
As for the evidence…
Xu Ying had just observed the entire picture of the core of the World Tree. The scarlet color of the lower part close to the ground was obviously heavier than that of the upper part, which confirmed her guess.
The scarlet light shines from the bottom up, and the white crystal is not completely transparent, so naturally the color becomes lighter as it goes up.
At the very top, the red is already very light.
Strictly speaking, this is not a scarlet World Tree Core, but a gradient colored World Tree Core.
From bottom to top, it gradually changes from a darker scarlet to a bright white.
It’s just that the entire crystal is too large, making it difficult to observe the entire thing, and everyone was shocked by the scarlet light, so they didn’t notice this situation at first.
"In other words, this scarlet light is actually emitted by the scarlet crystal?" Zeng Tao finally understood, and then said excitedly, "Then aren't we very close to the scarlet crystal now! The crystal is right under our feet! We can even see the light, it's so close!"
"Although it's right under my feet..."
Qin Fu stepped on the ground and said helplessly: "But we don't know how to get down. The guy who knew how to get down just died."
Everyone looked around.
Yeah, how to go down
The scarlet crystal is just around the corner.
