Tenjo Hikari indeed had no expertise in this area, nor did he understand the related knowledge at all.
But Tierra was different.
As the "Goddess of Rebirth," she understood this area to some extent.
Of course, although Tierra was the "Goddess of Rebirth," she was not a God in the true sense of creating worlds, but a "God of life and death," the God overseeing the cycle of all things in the world.
However, despite the different jurisdictions, it didn't mean that the divine authority Tierra exerted did not involve this area.
One simple fact was that the "DT" world wasn't simply a "planet."
Although the story of DT Planet started with the infamous Cosmic invasion by Worms, it didn't mean this small "DT Planet" was so ordinary.
Not mentioning the various forces fighting fiercely amongst each other, just the Natives at that time, there were many who could wrestle with "Cosmic-level Influence," and hidden within this planet was an "Alternate Space."
That is...
"The Fabled Realm."
The Fabled were Ancient Gods sealed away by DT's inhabitants in ancient times, truly belonged to the "Divine-Type." Despite their scale, quality, and specifications being incomparable to the Goddess of Rebirth, their status still far exceeded that of ordinary life.
In the Fabled Realm, there even exist three layers of worlds. Although it is a seal, these Fabled, The Fabled, and creatures living inside lead normal lives, not much different from the real world.
There are civilizations, educational institutions, training centers, and research institutions, it's a special space different from a planet.
And this, obviously, is truly the work of "God."
Whether it's a world created by Tierra or the similar methods used by Sofia to seal Tierra, most things on DT Planet can't be separated from the two of them.
Even if this so-called "Fabled Realm" wasn't created by Tierra, she possesses the related knowledge and some abilities.
Tierra thought this way and acted accordingly. She took two hours to carefully investigate the Vampire Kingdom using her current power, and then made her judgment.
Unsparing, in no more than twenty years, the Vampire Kingdom would directly collapse.
"What? Twenty years!? No, that's impossible—" This time, even the Fraulein was startled, concentrating, unlike the lazy lady, like a female General ready to go to battle anytime, "No, impossible... When I investigated before, it just was slowly dwindling, twenty years? Impossible, it wouldn't be that fast, at least, two thousand... two hundred years!
With the blood demon compatriots maintaining this Dimension, it can be delayed, absolutely!"
No matter what, it didn't believe this conclusion, meanwhile, those Spirits listening to the result similarly shouted, completely disbelieving this number, and many even doubted Tierra's abilities.
"I'm speaking of the result." Tierra looked at the Spirits who dared to question her calculated [result], scanning them briefly, behind her seemingly endless blue flames blazing fiercely, all Spirits, whether the Vampire Fraulein or ordinary Vampires, whether "existent but yet to be born" new Spirits, or the Undead Duke of such ancient Spirits, even Camilla, a true Vampire, were left mute.
In that brief moment, they seemed to feel their hearts being lifted up to weigh, seemingly used on the balance scale like data, ready to receive a "judgment" at any time—Judgment of death!
Tierra coldly snorted, uninterested in discussing her wrath or displaying her Divine Might to them, she didn't care for such trivial matters.
She was merely impatient.
When she speaks the conclusion, they should listen obediently.
Several Spirits in the Great Cosmic Workshop receiving help weren't surprised.
His Highness Tierra was like this, she rarely took an interest in anything, if you need her help, you may try requesting her assistance, she will decide based on her mood.
But—there is one thing you must never do.
Namely, to question Tierra, to question her judgment or calculations.
She held up one finger, facing all the Spirits, especially the Vampire Spirits, and said: "Perhaps in your eyes, this shattered Dimension still seems firm. With your continued protection, it can exist for hundreds or thousands of years.
But it is a foolish judgment, no, perhaps—self-deception."
"If this Dimension was truly so safe, would your leaders have left here to seek answers or have now completely vanished without a trace?"
The Vampires fell silent.
"Indeed, at the current rate of destruction, this Dimension wouldn't collapse so quickly. However, this rate of collapse is gradually increasing." Tierra crossed her arms coldly, saying, "With this past year's understanding and knowledge of Spirits, most Duel Card Spirits are incredibly respectful and compliant with duel results and contracts.
Although you, this Vampire Spirit, are not top-tier, you are nonetheless a clan leader, and having been defeated by Tenjo Hikari, you merely paid with your card while your body insisted on remaining here because you also vaguely sensed it?"
