"Hoo ......"

"There's really something else going on here."

After exiting the somewhat oppressive water, Ronald sat down on a bulge on the edge of the cavern and breathed a sigh of relief.

The first time he came here, Ronald first looked at his surroundings.

Confirming that there was nothing else here, Ronald did not rush to explore the situation, but sat on the edge of the water and whispered the spell of his spell.

The purpose of this action is to cleanse the body.

Although Ronald was able to move smoothly in the water before, the spells of Origin of Species could not help him dry his clothes. After swimming for such a long time, the clothes on his body were inevitably completely wet.

Being stuck to your body with sticky clothes is definitely not a comfortable experience.

“……”

Soon, the not-so-long spell slowly ended.

Ronald's damp clothes were quickly drained of moisture, and he returned to a fresh state from that whole slimy state.

"It's a lot better."

Ronald whispered a sigh of comfort to himself.

He then got back to his feet at the water's edge before going deeper into the tunnel.

This underground crack that appeared due to the earthquake is long and long, and there is plenty of space, which also brings a more convenient environment for Ronald to move forward.

Walk in a tunnel with a slope of about 30 degrees and keep going down.

While Ronald was indifferently advancing, the [Astrolabe] spell continued to record the surrounding terrain without stopping.

Compared to the exploration in the ice fields above, this part of the journey is even more monotonous. Except for the structure itself, which can make Ronald a little curious, the other aspects of the tunnel are completely unremarkable.

On the topographic record of the [Astrolabe] technique.

Except for the calm and unchanging passages around it, everything was filled with soil and ice, even behind the invisible walls. It's as if the tunnel that Ronald is advancing through at this moment is the only way to the underworld.

“……”

However, in the face of the monotonous record in the [Astrolabe] technique, Ronald is now a little happy.

The only channel means it's the only option.

Along with this situation, the crack that Ronald found in the volcanic tube that runs diagonally downward is also increasing as the right path.

Another few minutes passed.

Finally, at the end of the crevasse, Ronald noticed that the terrain had changed.

He was now quite far under the ice sheet.

The ground under your feet is the Arctic continent covered by ice and snow, and the polar ice and snow above and around are covered by it.

According to common sense, the front should also be in the same vein as the environment here, and there will not be much change.

However, if you put the angle of view on a horizontal plane, you can compare it.

After all this time of traveling, Ronald's actual vertical position was close to the flat ice field on the previous ice sheet.

Just ahead, the map recorded by the [Star Map] also confirms this.

The slender pipes reappeared, stretching from the ice overhead to the ground where they came into contact, each of which went straight to the surface of the real soil of the Arctic continent.

And the soil part.

It's also different from the ground Ronald is walking on now.

A number of regularly distributed spiral craters emerge abruptly from the ground and continue down to deeper levels. At the same time, there are also pits in other locations that intertwine with each other below, forming a strange and unique underground labyrinth that is connected with each other.

Such terrain.

It's not something that can be described by words like magic!

If you compare the Cretan labyrinth that Ronald once passed through with this place, there is also an unbridgeable gap between the two.

As long as someone walks to a place like this......

However, if he does not have Ronald's hands, he has a terrain recording spell or pathfinding ability similar to [Astrolabe]. Then as long as he walks into it, this dark underground world is the coffin where he is buried, and there is no possibility of escaping from it.

Aware of these phenomena, Ronald continued to move forward at an accelerated pace.

There was also a slight emotion in his mouth:

"I thought that in this world, only those spellcasters like to build their own bases underground."

"As a result, it seems that this dust beast likes to burrow into the ground more than humans?"

This is a phenomenon that Ronald has actually experienced.

If on the mysterious side, there is occasionally a situation where his own school is arranged in the ground building, then the three dust monsters that Ronald has personally experienced have all buried themselves under the ground.

The comparison of the probabilities of the two sides is almost clear at a glance!

And in the face of such a new change, Ronald's choice is also very direct - continue downward!

He's been tracking the Arctic continent all the way from Entrode.

At this time, how could a labyrinth, which seemed a little troublesome, stop him from continuing his downward path?

Soon, Ronald arrived at the location recorded by the [Astrolabe].

Come here in person and look at the details of these spiral pipes in front of you.

Everything in front of him made him even more amazed.

The tunnels, which continue downward, are all in the soil, but the walls are so smooth that they seem to have been carved and carefully ground by the finest craftsmen.

For such a finding.

Ronald had a very clear judgment in mind.

This is a state that can only be guaranteed under frequent external erosion.

Otherwise, whether it is an underground environment or over a long period of time, no matter how smooth the walls of these pipes may be at first, they will become rougher over time.

The only explanation is the Lingguang Mountain, which appears and disappears every few months.

These underground passages should have something passing through them during this time, and at the same time these passages have been constantly polished to keep them smooth.

This is the only experience.

In order to ensure that this state can be maintained for a long time

At the same time, there is also an obvious point in front of Ronald - there must be surprises waiting for him below.

Even if you bet on the smallest odds, it's not a dust beast hidden here.

Then there's definitely something very amazing about it.

"I hope I can find it soon......"

Thinking so, Ronald leaped forward and jumped neatly into the nearest spiral passage in front of him.

Smooth wall pipes, spiral downward slope trend.

After giving up his body to such a shaped tunnel, Ronald himself voluntarily gave up maintaining balance, and this is almost a natural amusement park slide.

While constantly adjusting the downward direction through the map of the [Astrolabe].

Ronald was like a child playing in a playground, sliding all the way to the depths of the earth......
