Chapter 27 [Towards the Sky, Part 2 - Application]

"Romulus, Remus, they say the walls of the dungeon, like Romulus, Remus, and the dungeon walls are considered indestructible, right? Are they simply hard?"

"No, Lord Crow. While they are certainly hard, the crucial aspect is their ability to instantly absorb any applied force, be it physical or magical, converting it into the dungeon's energy."

As expected, if it completely absorbs kinetic energy, the dungeon remains undamaged.

"Romulus, hypothetically, if you were to install dungeon walls outdoors, against gusts of wind or lightning..."

"No impact whatsoever."

"What about gravity?"

If dungeon walls nullify gravity – or rather, gravitational forces – they might defy not just Earth's gravity but even the sun's, potentially soaring into space. If they don't escape, they are likely bound by gravitational forces.

With Romulus and Remus' cooperation, experiments were conducted by placing walls outside the dungeon, revealing that the connection to the earth is a significant factor. However, using my "Broken Dungeon" skill, I can create independent dungeon walls...

The dungeon walls created with "Broken Dungeon" were initially affected by gravity. However, by imbuing magic with the intent to neutralize gravity during creation, fragments of the walls were liberated from gravitational constraints, soaring beyond the sky. The required speeds for escaping Earth's gravity and the solar system's gravity are approximately 11 kilometers per second (second cosmic velocity) and 16-17 kilometers per second (third cosmic velocity), respectively.

"Lord Crow, it's not about breaking free with speed or kinetic energy; perhaps a more moderate speed?"

If gravity is eliminated, only Earth's rotation-induced centrifugal force acts on objects on Earth. Considering the rotation speed is around half a kilometer per second, it wouldn't reach the first cosmic velocity. However, if unaffected by Earth or the sun's gravity, escaping the solar system at that speed could be possible...

Unsure if my calculations are correct due to being out of my field, outdoor experiments were halted for safety. I don't want to unintentionally create the world's first artificial satellite.

Continuing experiments within the dungeon, holding fragments of dungeon walls and gradually neutralizing gravity with magic made them float, with adjustable height.

"Lord Crow... I never imagined such things were possible with Dungeon Magic..."

Well, my Dungeon Magic is far from ordinary. It's quite broken...

A good opportunity to appraise my abilities after a long time.

[Individual Name] Karasumaru Nagayuki, Crow

[Species]????

A person from another world who fused with a dungeon core during the shock of moving to this world. Acquired few skills due to the immature dungeon core, but subsequent inter-world travels accumulated immense distortion in the body, resulting in possessing abnormal magical power. However, currently lacks magic skills related to magic release, limiting magic use.

[Position] Dungeon Ruler

[Level] 7

[Unique Skill] "Broken Dungeon" Level 5

Can create a dungeon within a radius of thirty meters from oneself. The size of the created dungeon depends on the user's level. Can instantly move within dungeons created by oneself. Can freely move between dungeons by setting up dungeon gates. Can alter the internal structure of dungeons at will. Can generate and nurture dungeon cores. Can envelop oneself with abilities similar to dungeon walls. Can summon monsters within dungeons. The types of monsters that can be summoned depend on the user's level. Can control undead inside and outside dungeons. The number and range of undead that can be controlled depend on the user's level.

[Skills] Language Understanding, Appraisal, Subordinate Strengthening, Telepathy

Finally became an unknown species...

No, not that... let's focus.

The level of "Broken Dungeon" has significantly increased. It was level 2 last time. The regeneration of Romulus and Remus, and the creation of new dungeons, must be having an effect. Surprisingly, the position has also upgraded to "Dungeon Ruler." In the explanation of "Broken Dungeon," it mentions being able to envelop oneself with abilities similar to dungeon walls...

In conclusion, without the need to create dungeon walls, I could float in the air using the same method as with dungeon walls. It's levitation. If I can somehow manage propulsion, like wind magic, I should be able to achieve my long-desired flying magic.

But, about the "abilities similar to dungeon walls"...

"Romulus, suddenly, can you use any projection-type magic?"

"Huh? ...I can handle something like a ball."

"Good, just lightly, can you shoot one at me?"

"Utterly absurd... but may I ask for the reason?"

"I seem to have gained abilities similar to dungeon walls, like projection magic."

"I see... In that case, let me shoot a water ball. Even if it's light, it should have some impact, and if it's nullified, you'll know."

So, I had him shoot it. For comparison, we tried without activating the skill, but the result was clear. By gaining the abilities of dungeon walls, I completely nullified the impact of the water ball. However, getting wet with water couldn't be avoided. I tried with earth, wind, and fire, and all could be neutralized. Considering the same could be true for physical attacks, I obtained complete immunity to all attacks. Still, it's dangerous to rely too much on defense, as attacks like poison, disease, and curses, which dungeon walls can't neutralize, might exist. The policy remains to be inconspicuous and reserved. Well, it's a bit reassuring.

Now, I just need wind magic or some other propulsion method.
