"I'm sorry." Wen Guixin felt a little guilty, "If my control was stronger..."

"What are you sorry for?" Wang Lei waved his hand, "If it weren't for you, we wouldn't be able to get in. We'd better take a quick look around to see what's around."

"Too."

Xu Ying's attention at this time 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.

Everyone else's eyes 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? Isn't this the 'source of life' of the alien invaders we are looking for?

"

"No." 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 will make people uncomfortable. We are not from those factories.

Did you steal a lot?"

Xu Ying touched the backpack she had been carrying on this trip.

She and Xu Xin each took part of it, and now she has more than a dozen of those small scarlet crystals in her backpack.

"But the light emitted by this crystal is very soft. To be honest, it is quite comfortable when it shines on the body." Qin Fu shrugged, "So, this cannot be what we are looking for."

Indeed.

No matter how you look at this crystal, it doesn't look like the target they are looking for.

"But, is this the core of the World Tree?" Zeng Tao asked doubtfully, "Isn't the World Tree a product created using the earth's white crystals? Why is the core of this World Tree scarlet?"

"This is their base camp." Wang Lei felt that this matter was easy to explain. "Isn't it normal for their base camp to be special? Maybe the World Tree's genes have mutated?"

"Are you kidding..." Qin Fu was speechless, "This is scarlet crystal..."

"What on earth is going on...?" Xu Ying also thought of the problem at this time.

She felt her heart tightening.

What is scarlet crystal?

It is the source of life for alien invaders!

They knew before that the process of converting crystals from white crystals into scarlet crystals was extremely cumbersome and impossible to achieve on Earth. The crystals had to be sent back to their home planet.

Because of this, the concentrated scarlet crystal is extremely precious.

Their plan is also based on this. If the concentrated scarlet crystal is destroyed, the alien invaders will lose their source of life and flee in panic.

But the huge, non-condensed scarlet crystal suddenly appeared in front of them, as if mocking their plan.

If alien invaders can already create scarlet crystals on Earth, then their plan will be useless!

"I asked, can we go back home?" Qin Fu looked at the giant scarlet crystal and felt that he had lost his motivation.

He also thought about the meaning of this huge scarlet crystal.

"...No, this kind of thing is impossible." Xu Ying walked towards the scarlet crystal.

It should be impossible for alien invaders to refine scarlet crystals on earth.

There's something wrong with this giant scarlet crystal!

The closer she got, the more she felt something was wrong.

Because the closer she got, the more comfortable she felt, and she even felt relaxed.

This is the characteristic of white crystal.

She walked to the huge crystal and reached out to touch the crystal.

"...This is not a scarlet crystal." She slowly relaxed her frown and exhaled a long breath, "This is the normal core of the World Tree, a crystal white crystal."

"White crystal?" Zeng Tao raised her head and looked at the whole crystal, "But it's red?"

Xu Ying was also a little puzzled by this.

Although the properties displayed are completely those of white crystal, why does it show the color of scarlet crystal?

Somewhat weird...

Um?

Xu Ying thought of a possibility.

Her eyes slowly opened wide.

"Ah, I know!" She clapped her hands, looked up at the huge crystal in front of her, and gradually backed away.

As she retreated, gradually, the entire core of the World Tree appeared in her field of vision.

After seeing the whole crystal clearly again, her eyes became brighter: "I know what's going on!"

"Ah? What's going on? Isn't this really a scarlet crystal?" Wen Guixin asked.

"No, of course not." Xu Ying said with a smile, "However, this scarlet light has something to do with our goal."

Several other people were puzzled.

What's the meaning?

"Think about it, where can we see the core of our World Tree in 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 the others are now, you can see the core of the World Tree.

The underground space is an area wrapped by the roots of the World Tree, and directly above the entire area, part of the core of the World Tree is exposed.

The reason why that area is very bright is due to the light emitted from the core of the world tree that is partially exposed at 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 the underground space, and the lower part of the core is exposed in the underground space. The upper part of the core is exposed in the hollow area in the center of the trunk of the World Tree.

That is the area where they are now.

In layman's terms, the core of the World Tree is stuck in the ground, with the underground space below and the hollow area of ​​the trunk above.

"Oh..." Qin Fu suddenly realized, "So that's it."

"What is it like?" Zeng Tao turned to look at him, with a look of curiosity on his face, "Why is this happening?"

"What do you think is the target we are looking for now?" Qin Fu asked.

"You mean that scarlet crystal? Isn't it in the underground space?" Zeng Tao pointed down.

"Oh!" Wen Guixin also understood, with the same astonished expression, "I understand too..."

"What? How come you all understand?" Zeng Tao looked confused.

"Not everyone understands, at least I don't understand." Zhao Xiaochuan pointed to his nose.

"I don't understand either." Wang Lei scratched his head.

Xu Ying explained to them.

The reason is actually very simple.

As mentioned just now, underneath the core of the World Tree is the underground space, and the scarlet crystal that emits extremely dazzling scarlet light is located in the underground space of the World Tree.

The light emitted by the scarlet crystal reversely penetrated the core of the World Tree located in the dome of the underground space, illuminating the entire core of the World Tree blood red.

The core of the World Tree is like a lens, allowing the light of the scarlet crystal located underground to pass through it to the ground and to where Xu Ying and the others are now.

Therefore, they saw such a core of the World Tree that seemed to be emitting scarlet light but was actually very normal.

As for the evidence…

Xu Ying had just observed the entire core of the World Tree. The scarlet color of the lower part near the ground was obviously heavier than the upper part, which confirmed her conjecture.

The scarlet light shines from bottom to top, and the white crystal is not completely transparent. Naturally, the higher it goes up, the lighter the color will be.

At the 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 relatively heavy scarlet to bright white.

Just because the whole crystal was too big to observe the whole picture, and everyone was shocked by the scarlet light, they didn't notice this situation at the first time.

"In other words, this scarlet light is actually released by the scarlet crystal?" Zeng Tao finally understood, and then said excitedly, "Then we are very close to the scarlet crystal now! The crystal is right under our feet.

!You can even see the light, so close!”

"Although it's right at your 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.

Yes, how to get down?

The scarlet crystal is already close at hand.
