After declaring their "dominion" over the spirits and this area, Gaia turned back to find Tenjo Hikari.
Tenjo Hikari was still as usual, routinely checking his deck.
Gaia had brought many new cards for Tenjo Hikari.
Besides the Gateway to Chaos, there were also Gaia The Fierce Knight, Swift Gaia the Fierce Knight, Soldier Gaia The Fierce Knight, and Charging Gaia the Fierce Knight, a total of four different forms of himself. Additionally, there was a support card like Spiral Spear Strike specifically for Gaia the Dragon Champion.
Among them, Soldier Gaia's inclination is towards "polymerization," and Charging Gaia's inclination is towards "Black Luster Soldier."
Unfortunately, there was no Gaia the Magical Knight.
One could only say, worthy of having crossed the trial of the Black Luster Soldier, becoming one of the "Strongest Warrior," the form cards he alone possessed were already catching up to Captain Crystal after Tenjo Hikari's supplementation.
However——
Tenjo Hikari quickly took Gateway to Chaos and Spiral Spear Strike out from the deck.
These two cards did not become Fusion Spell Cards; on the one hand, not all cards would instantly fuse into Super Polymerization, and on the other hand, his control over Super Polymerization had also improved.
But this did not mean that he could just keep them in the deck forever.
Cards like these, which symbolize factions and clans, are better left to Gaia.
Gaia scratched his head, opened his mouth, hesitating to speak.
"What's the matter, Gaia?" Flame Sword broke the silence in a timely manner.
"Ha. This spirit probably wants to stay here to take care of those weak creatures," Tierra saw through Gaia's thoughts directly, "then you should just stay here."
"Ah? But... since I've crossed the trial and finished the punishment from the Black Luster Soldier, of course, I should follow my lord..." Gaia was still a bit reluctant to say it.
He looked at Tierra, a bit puzzled as to why this spirit was so "free."
"It's okay, Gaia," Tenjo Hikari shook his head, "actually, you staying here fits perfectly with our intentions."
"Eh? Is that the case?"
Gaia was somewhat confused.
Flame Sword slightly turned his head, noticed Tierra had no interest in explaining, coughed, and for a rare moment, considered his words before explaining the general situation over the past year to Gaia.
He called it — The Great Adventure of the Fusion Master!
Besides meeting various spirits and defeating them, fighting against the evil Fusion Army, he especially mentioned Tenjo Hikari's identity and profession.
Identity — Second-year student at the human Duel Academy.
Profession — Alchemist.
Now, Tenjo Hikari is preparing for the academy's internship, exams, and competitions, visiting this dimension in advance, also preparing just in case, by using alchemy to set up a Dimension Gate here.
Originally, he wanted to find a remote location, where no one would discover the Dimension Gate, ensuring as much as possible the safety of setting up two Dimension Gates capable of two-way teleportation.
And now, if Gaia stays in this domain, then they can completely use this area as a base, to directly build the Dimension Gate in the core area.
This would further improve security.
Of course, if Gaia is really worried, there is another method, which is to take those weak spirits he saved with Tenjo Hikari directly to his "Great Cosmic Workshop" dimension.
This sub-dimension constructed by Teacher Daitokuji is astonishingly large, enough for Gaia to take the spirits there to live.
"No, my lord, I think this is unnecessary."
After hearing this suggestion, Gaia shook his head.
He indeed saved these spirits and indeed couldn't rest easy with them.
But for him, what these spirits are thinking about is also unknown, he can guard these spirits, but to rashly take them to Tenjo Hikari's "workshop," that's a no.
What if there truly were remnants of the Light Monarch?
He's just worried, not the "elder" of this group of spirits; as a warrior, guiding and training other warriors to become independent is the warrior's way.
If given this time, and not a single warrior mastering the Duel Ceremony is born from this group of spirits, he feels it's better to let them scatter and escape, living in various safe settlements.
"Then... my lord, what exactly is that light?" Gaia had a question he couldn't keep in his heart, so he asked.
Those curtains of light exuding black mist were ominous just by looking at them.
Logically, as one having completed the warrior trial, even without the Black Luster Soldier Card, dueling with a "Warrior-Type" from an ordinary dimension wouldn't end so disastrously. But when dueling the Light Monarch, he had three seven-star Monsters from the start, and the duel process had not a single smooth point, he was virtually suppressed the entire time, barely holding out through skill.
This was too preposterous.
"That strange light..."
Tenjo Hikari, while recalling, spoke with them: "It is said to be called [Light of Destruction] or [Wave of Light]."
Light of Destruction.
The first time in the original work where it got a "definition" was in the words of President Pegasus, the initial boss in the original "Yu Gi Oh" and father of Duel Monsters, explaining to Principal Samejima.
Wave of Light was a light source discovered by the Industrial Illusions Company in some distant cosmos through Duel Astronomy.
It is a wave of light filled with desires of destruction and annihilation, and life irradiated by this wave will fall into endless struggles.
In ancient times, from Egypt, Rome, to modern World War II, the reason humans waged wars was all ignited by this wave of light.
Yes, in this world, the concept of "battle" and "war" itself was born because of the Wave of Light.
It is not purely human selfishness, but also partly due to the influence of the Wave of Light.
Moreover, combat, warfare, and destruction would also enhance the Wave of Light itself, making it stronger—likewise, the stronger it becomes, the stronger the existences it influences.
So, theoretically, as long as there is still struggle, it will never completely dissipate.
After Duel Monsters were discovered by Pegasus and after the cards of the Three Egyptian God were successfully created, someone also successfully made a reality-defying card, thereby attracting the attention of that light source.
At that time, due to the presence of "Duel Monster Card," the Wave of Light spanned countless distances, projecting its power onto that card.
Hmm...
Source of all evil, Ultimate D! Destiny Hero - Plasma!
In the original, a part of Principal Samejima's reason for hosting the GX Tournament was due to a request from President Pegasus, to search for that legendary D Card.
Unfortunately, they did not know that the Light of Destruction housed within the D Card had long become an empty shell.
And in this world...
It appears that due to the development of dimensional teleportation technology, the Light of Destruction even wants to meddle in the struggles of the Spirit World.
It's also understandable.
After all, even an egghead could receive support from the Wave of Light, not to mention others.
In the world and across dimensions, there are endless people and spirits that wish to gain strength through the power of the Wave of Light, which is not strange.
Indeed — from the perspective of those possessed, the Wave of Light didn't require them to pay anything, it merely attached itself to them, even providing them with enhanced card draw capabilities, and the more formidable ones, like the four elements under Saiou's sister, could undergo elementalization, transforming into lightning, ice, fire, and rock for teleportation.
That is genuine superpowers——
Even further.
At the level of what Saiou received, it became even more absurd.
Precognition of the future.
And with almost 100% accuracy.
Only Saiou himself understood, even as a child, the danger of the Wave of Light—eventually, the host will head toward self-destruction!
Otherwise, with this ability, even Kaiba would have to tribute Obelisk to the summon Blue-Eyes White Dragon to break destiny.
Moreover, Saiou himself had small skills like mind control, remote communication, and Light Power Psychic Strike, evidencing the Wave of Light's favor on him.
Although Saiou Takuma initially loathed conflict in his soul, his physical conditions were too perfect! How could it be overlooked!
Of course, Tenjo Hikari didn't reveal all he knew to the spirits, he just generally explained his "understanding" of this light and warned them of the dangers of this Light of Destruction, then reminded them to be cautious.
As for President Pegasus's discoveries, his speculation on the Wave of Light, those were irrelevant.
"I see... Such a terrifying existence indeed," Gaia's brow furrowed into a swirl, "Then, my lord, do you need me to summon spirits to serve as workers to help you build the Dimension Gate?"
"No—sometimes knowing less is better, and with the components from Wanrong, it's enough for assembly."
With Gaia as a "local," Tenjo Hikari would not have to spend time exploring the outside, allowing him to set up the Dimension Gate earlier, preparing for the future.
With preparation, there's also confidence in the heart!
