Suddenly, patches of blue and purple light appeared in his eyes.

There's even a golden glow.

"As expected." He couldn't help but raise the corners of his mouth.

"What's so true? What did you see?" Wen Guixin's voice came from over there, and everyone in the Explorers should have gathered.

Because they knew that Xu Xin had already found a way to enter.

"I'll be out right away." After saying that, Xu Xin hung up the call.

Behind him, the somewhat irregular wooden ball had completely appeared on the ground.

In fact, this is not a wooden ball, but a wooden pillar with a prototype on the top.

The irregular wooden door on the pillar is the exit.

"Let's go back."

Xu Xin walked to the door. The door opened automatically and several people walked in.

Still a vine ball.

It was very dark inside, so Jin Yue took out the core of the tree house for lighting.

When the wooden door is closed, the vines begin to grow and eventually cover the door.

Xu Xin thought, a slight feeling of weightlessness appeared, and the vine ball began to fall downwards.

"Didn't we come in through the thick roots outside?" Lou Fei'er reached out and touched the vines, "There are many such thick roots outside, are those... all entrances?"

"It should be all." Xu Xin nodded.

"Although they are all entrances, the distance between roots is not that far, only a hundred meters at most. But if it is inside, it is not that close." Shi Wanyun said in a soft voice, "After all... the area has expanded.

hundred times."

really.

As it should be.

Entering from different roots, the appearing positions are also different, and there should be a considerable distance between them.

"Why haven't we arrived yet?" Zeng Tao was a little surprised, "Wasn't it only ten seconds when we went up? Why does it feel like it took half a minute to go down?"

"Because I want to go underground first." Xu Xin said.

Their current location is already underground.

Based on the previous rising speed, the current position of the vine ball should have reached 100 meters underground.

But it still continues to decline.

After another ten seconds, the vine ball slowly stopped.

The vines retracted and the heavy wooden door appeared again and opened automatically.

The soft white light directly filled the entire vine ball.

"Ugh!" Coco screamed in surprise.

"...It's so bright underground!" Zeng Tao was the first to walk out of the door, "Is this underground?"

It's underground.

Walking out of the wooden door, Xu Xin immediately discovered that what was under her feet was not soil.

Rather, they are the roots of a thick world tree.

He looked up again.

At a glance, he saw a hundred meters in the sky, a huge crystal ball emitting white light "embedded" in the dome, with only half of the ball exposed.

And this core is like the sun, emitting bright white light, shining on this area.

This is why, although it is underground, it is very bright.

And around this "sun" are countless thick roots. You can't even see the soil, they are all twisted roots of the world tree.

The top of the entire space is composed of the roots of the World Tree.

"Is that... the core of the World Tree?" Lou Feier looked up and exclaimed, "It's really big."

Very big.

Judging from the exposed half of the sphere, the radius of the core is more than ten meters.

The whole thing should be a... giant core with a diameter of more than 20 meters.

Really big.

This is only more than ten meters in diameter than the trunk of the World Tree.

Hanging on the top of the head, looking up, it still feels a bit oppressive.

Xu Xin looked around again.

This space is not as big as the World Tree, it is like a small world.

It's obviously only about two kilometers in radius.

If the World Tree was not affected by the ability of time and space, the World Tree tree house above would probably be this big.

And the ends of the surrounding area are not soil and rock walls, but the roots of the World Tree.

This entire area is wrapped by the roots of the World Tree!

Everywhere, everywhere!

This place is really interesting.

"Is it a space wrapped by roots..." Shi Wanyun looked around, then looked up at the core of the World Tree, "It is also very safe here. After the World Tree matures, the roots should not be destroyed as easily as before.

Well, this place is equivalent to a place completely protected by countless roots."

"What is this? An underground shelter?" Lou Feier stepped on the thick roots under her feet, "There's not even soil. The ground is covered with such thick roots and it's not even."

"Okay, let's talk about functions and stuff later." Xu Xin held down Coco who was about to jump off his shoulders, "Let's go back first."

The rest of the Explorers are still waiting for him.

Several people returned to the vine ball.

"Hmm...?" A trace of surprise flashed in Xu Xin's eyes.

At this time, several people felt weightless under their feet again, and the vine ball suddenly began to fall again, and the speed was much faster than before!

"What...what's going on!" Lou Fei'er grabbed Xu Xin's arm, "Are we falling down?! Aren't we going up?"

Xu Xin's other arm was grabbed by Zeng Tao, and she panicked and said, "We're not going to fall to death, are we?"

"Don't panic, I'll let it go down." Xu Xin hurriedly explained, "Because we can continue going down."

"Is there a second underground floor below?" Zeng Tao complained, "It's not a shopping mall garage."

The feeling of weightlessness worsened again.

The speed of descent has once again improved!

This time even Jin Yue and Shi Wanyun caught the people around them.

"Why is it so fast?" Jin Yue asked doubtfully, but she believed in Xu Xin's judgment, so she was not worried.

"We are going to the underground world." Shi Wanyun's tone became a little curious, "Xu Xin, have you and Lou Fei'er been to that underground world?"

Underworld.

That vast world that goes at least several kilometers underground.

Xu Xin has not gone down since the last time she explored the underground world.

"I'm not really going to enter the underground world." Xu Xin felt the weightlessness at this time and said to herself.

Judging from the feeling of weightlessness, their descending speed should be six to seven meters per second now.

Any faster, and it would be directly equivalent to free fall.

Falling at this speed for so long without stopping, this is really the pace of the underground world!

The World Tree is actually connected to the underground world!
