CHAPTER 753: 592 SHE, IS STILL ALIVE...?

What is the Supreme Domain?

It’s far from any ordinary ability.

In the Demon Slayer World, the Supreme Domain is considered a realm attainable only after one has pushed themselves to their limits and endured pain.

Akaza spent hundreds of years pursuing this domain but failed to reach it until his death.

Not all the nine pillars of the Demon Slayer Corps reached this domain in the final great battle; many had not even touched it.

This ability, even Reiger, was awakened only after undergoing countless hardships while improving the Sun Breathing technique, and Kamado Tanjirou, the original protagonist, didn’t even awaken this ability due to Reiger’s arrival.

Thus, in the three-piece set of Demon Slayer abilities, the Supreme Domain is the hardest to awaken, the hardest to possess, except for Tsukiguni Yoriichi, who was born with the natural ability to awaken the Supreme Domain. The rest of them went through incredible trials before finally awakening it.

And Liz has already awakened this ability?

How long has she been learning the breathing techniques?

Barely a month at most, right?

In less than a month’s time, she has already awakened the Supreme Domain?

What kind of talent is this?

Reiger looked at the little princess quite dumbfounded, making her feel uneasy.

"Did I, did I do something wrong, Master?"

The princess’s voice carried a hint of a sob as she asked.

"...No, you did well," Reiger sighed, patted Liz’s head, and said, "Remember the feeling just now. The ability you just used, if applied properly, can really help improve your strength, understand?"

Liz nodded repeatedly, indicating she understood.

Afterward, the two adjusted their emotions and found the box containing part of the Nibelungen Pillar structure at the place where the magic puppets had turned to ash.

Reiger opened the box and checked its contents.

Inside was some gold dust, which appeared ordinary at a glance but upon careful examination revealed a faint glow pulsating, forming mysterious runes—quite magical.

"What did those guys want this stuff for?"

Reiger wondered as he looked at the gold dust.

"What exactly is their goal?"

Unfortunately, the answer to this question couldn’t be uncovered for now.

Reiger and Liz searched the stone hall and found traces of someone leaving the place.

"Sgranot Bayard?"

The lord of Xinjele seemed to have already run off, no longer staying here.

Reiger found footprints suspected to be Sgranot’s behind the statue, footprints that showed hesitation, proving that the person, upon leaving the underground magma area and reaching this stone hall, had discovered this hidden passageway and deliberated whether to enter.

In the end, perhaps truly apprehensive, the person chose to flee and did not enter the hidden tomb.

"It seems the lord of Xinjele is indeed very afraid of causing trouble in this ancient ruin," Reiger thought less of Sgranot.

That man, though so domineering, showed such cowardice in the face of real danger—a typical bully who fears the hard and torments the weak.

And this, despite being an old Sword Saint, no wonder he can only hide in this Neutral Zone as a Land Lord, flaunting his power only within his own territory.

With that in mind, Reiger and Liz approached the hidden passage, looking at the path that led to who knows where, and exchanged glances for a long time.

"Should we go in, Master?"

Liz asked timidly.

"What about you?" Reiger countered, asking, "Do you want to go in?"

According to Reiger’s previous guess, this passage might lead to the tomb of the last queen of the heroic lineage.

She could well be Liz’s ancestor, certainly not just any ancient to Liz.

So, whether to disturb her rest was ultimately up to Liz’s wishes.

But Liz seemed somewhat conflicted.

Rationally speaking, she shouldn’t disturb her ancestor’s peaceful rest.

However, emotionally, Liz wanted to know if there was anything in the hidden tomb related to her own lineage.

What exactly was Reinnaier?

Where is the heroic lineage now?

And where is the Hidden Land?

The answers to these questions might lie ahead.

Of course, Liz didn’t have to choose to enter the hidden tomb.

In the farthest corner on the left side of the stone hall, there was another entrance that led to the slot compatible with the Sword of Moslo.

That was their initial objective.

Therefore, Liz could choose not to go to the tomb and instead head directly to the slot.

But even if she went there, whether or not to insert the Sword of Moslo into that slot was something Liz was still hesitating over.

There was no choice, for within this ancient ruin lay the sealed affiliate of the King of Calamity, an ancient fire dragon that had lived for at least eleven thousand years.

If that slot happens to be the seal’s node, and the Sword of Moslo the key to unlocking the dragon’s seal, then what?

If it really was like that, wouldn’t inserting the Sword of Moslo into that slot be tantamount to helping the fire dragon escape its confines?

If that were to happen, it would be a major problem.

An ancient fire dragon that lived for over ten thousand years, if it breaks free and returns to the surface, then not only the nearby Xinjele, but also the neighboring kingdoms of Genas and Leiblu could face a catastrophic disaster.
