The maid squad is too strong, what use is there for me, the Demon King?

There were no carvings, no runes, no lamps, no side paths, and not even a speck of dust.

The place is clean, simple, and cold to the extreme, as if all meaning lies only in the function of "leading somewhere," and all other decorations and redundancies have been completely discarded.

This extreme purity, ironically, reveals a chilling sense of purpose.

Gray moved at a moderate pace, his steps steady on the sound-absorbing tunnel floor without making a sound.

His entire being was focused on maintaining an absolute and controlled perception of his surroundings, while simultaneously being completely immersed in the increasingly strong guidance of his intuition.

The guidance no longer required him to think about the direction; it had become an instinctive inclination, like iron filings attracted by a magnet, like a river eventually flowing into the sea. His body spontaneously adjusted the frequency of his steps and the rhythm of his breathing, resonating harmoniously with the call from the abyss.

He could feel that with each step he took, the pure and dormant energy aura originating from the ancient demon king in the surrounding space became more intense, and its resonance with his own bloodline also strengthened.

The passage was like a blood vessel gradually awakening, and he was the long-awaited blood flowing back to the heart.

The concept of time becomes increasingly blurred here. It may be just a moment, or it may be several hours.

Finally, the scenery ahead began to change subtly.

The passage continued downwards, but the smooth walls on both sides began to gradually narrow inwards, making the passage slightly narrower. At the same time, in the darkness far ahead, a faint yet stable point of purplish light began to appear.

The light spot was not an external light source, but rather seemed to be the glow of energy emanating from the end of the passage itself.

At the same time, the call of blood, the guidance of intuition, reached an unprecedented intensity! It was no longer merely a call, but had transformed into a powerful sense of belonging and confirmation, like a traveler finally seeing the lighthouse of their homeland, telling them with crystal clarity—

The finish line is just ahead. The answer is within reach.

Grena's usually steady pace quickened slightly involuntarily. Even with his composure, it was difficult for him to remain absolutely calm in the face of this possible answer that spanned countless ages and concerned the fate of his people.

He quickened his pace toward the dark purple light, toward the ultimate source of the call.

At the end of the passage, the outline gradually came into view—it seemed to be a huge, arched entrance to a space, from which a dark purple light emanated, illuminating the last section of the passage.

No hesitation, no hesitation.

Gray took a step forward, finally leaving the long and pure dark passage and stepping into the final place, located in the core area of ​​the Silent City, which emitted a dark purple light.

His special senses instantly brought the scene before him into his "field of vision".

He believed that he would find all the answers he sought here.

Stepping out of the passage, the view suddenly opened up before me.

This is an extremely vast underground space, with a dome that seems to have no end, disappearing into the boundless darkness above.

There was nothing around, only the dark ground of the same material underfoot stretching endlessly forward until it disappeared into the edge of sight.

It was even more desolate here than inside the passageway, so empty that it made one feel small, as if one were in the heart of a forgotten world.

However, this extreme emptiness and stillness did not last long.

The instant Gray stepped into this space, the ground beneath his feet and the central area of ​​the vast space suddenly lit up with countless intricate, interwoven, and flowing dark purple magic patterns.

These patterns are not carved on the surface, but rather emanate from deep underground, spreading and combining rapidly like living things to form a massive, unimaginably large, three-dimensional magic circle.

A deep purple light replaced the absolute darkness, illuminating the space in a hazy and mysterious way. As the light flowed, countless tiny runes appeared and disappeared, radiating vast and ancient energy fluctuations.

At the center of the space, where the magic circle's energy was most concentrated, light began to distort and converge.

A figure, composed of pure light and shadow, is gradually outlined.

The figure was initially extremely blurry, flickering unstablely, accompanied by subtle, snowflake-like noises. But soon, it stabilized and became clearly visible to Gray.

That was the image of a young demon.

He appeared to be around sixteen or seventeen years old, with handsome features that still retained a touch of childishness. He had fair skin, soft, short silver hair that curled slightly, and a pair of small, exquisite purple-gold demonic horns on his forehead that shimmered with a gentle luster. He wore a simple yet well-fitting dark purple robe, its ancient style only accentuating his upright posture and giving him a serene air that belied his age.

When people talk about "sages," they usually think of an old man with a white beard, but the Demon King "sage" is actually a teenager.

This was not because he ascended the throne at a young age, but because it is said that his control over magic had reached a state of perfection, and he had deliberately solidified his physical appearance at the most vibrant and creative stage of his life.

Gray's deep gaze instantly locked onto the young man composed of light and shadow.

Even though it was just a remnant projection, even though it had traversed countless ages, the supreme primordial aura unique to the Demon King's bloodline, the specific lineage characteristics represented by the purple-gold demonic horns, and most importantly, the physical features of the "sage" provided in the Demon King's inheritance, all immediately confirmed the other party's identity for him—

The tenth Demon King, later revered as the "Sage"!

Gray was initially quite surprised when he saw that the "wise man" was actually a teenager.

That king, renowned for his wisdom, foresight, and profound understanding of the nature of magic, a legend even in the long history of the demon race, orchestrated all of this!

Actually, Gray wasn't too surprised by the appearance of this projection.

First, through the information provided by the Demon King's legacy, Gray clarified all the Demon King's movements after the tenth generation.

However, Gray did not find any demon king who had entered the desert, let alone found such a secret realm and built such a magnificent demon king's castle.

However, such a magnificent building could not have been built overnight.

However, Gray couldn't find anything incomplete in the records of the Demon King's inheritance. There were no blanks or discordant points, which ruled out the possibility that "a certain Demon King erased part of the Demon King's inheritance records."

This means that the Demon King's Castle could not have been built by a Demon King after the tenth generation.
