At this moment, as the members of the Ōtsutsuki clan returned to the interstellar array, Senju Yukika began to carefully observe the castle.
This castle was a base left behind by the ancestors of the Ōtsutsuki clan. Other than the interstellar teleportation array, was there really nothing else inside this base?
Senju Yukika harbored doubts, cautiously surveying his surroundings.
Just then, he suddenly felt his heart pound violently, as if an invisible current was pulling him toward something.
Looking up, he saw a bright white light emerging from the distant darkness, approaching gradually.
When it arrived in front of him, Yukika was surprised to see that it was a humanoid figure.
But it had no facial features, just a human-shaped mass of white light that appeared to be made entirely of chakra.
Senju Yukika asked coldly, "What are you?"
At the same time, the black wings of the Darkwing Demon King spread wide on his back. A fierce aura began to rise, and his eyes turned green with a hint of golden glow.
This transformation was because his template progression had unlocked significantly, causing noticeable changes in his form.
The white light didn't answer Yukika's question. Instead, it stretched out an arm-like appendage and formed a terrifying blade of ice.
With a slash of its weapon, the furious chakra clashed through the air, creating a spatial rift that rapidly spread toward Yukika's position.
In the next instant, Yukika disappeared from where he had stood. The place where he had just been was instantly erased by the spatial rift!
If he had been even a fraction slower, he would have been obliterated by that strike.
In a flash, Yukika reappeared behind the figure, thrusting his sword swiftly toward the white-bodied figure!
The speed of his sword was incredible, causing the air to ignite in a burst of blood-red flames.
This was the result of the sword's extreme velocity creating an explosive friction with the air, combined with the power of Ulquiorra, generating a dark crimson glow.
But strangely, the white light suddenly ripped apart on its own before Yukika's sword even made contact, breaking down into streams of white energy that floated in the air.
After swirling a few times, the light reformed at a distance, once again taking the shape of a humanoid figure.
The scene was bizarre. Yukika's pupils narrowed—this level of power had already far surpassed the ninja world.
Was this the overwhelming force that belonged to the vast universe?
Yukika had never witnessed the strength of the Ōtsutsuki ancestors, but this power was entirely different from anything in the ninja world.
Then, streaks of golden light flashed across the sky. After a flash of Cero, the entire world seemed to fall eerily silent.
The white light staggered slightly under the storm's onslaught and drifted off into the distance...
In that moment, the humanoid white light seemed to experience human-like emotions—a trace of confusion arose.
Yukika caught that emotional fluctuation precisely. The white light seemed incredulous as it spoke: "Who are you? What kind of world does this power come from?"
It had been born on the Ōtsutsuki's ancestral planet, yet had never seen anyone like Yukika display such astonishing power.
The sensation unsettled it deeply...
But Yukika didn't answer its question. His sword of annihilation traced a beautiful arc through the air, cleaving the white light figure cleanly in two!
As before, the white light used the same technique, the two halves merging again in the distance to reform as one.
However, its gaze toward Yukika was now filled with intense unease, even a flicker of panic.
"To have both chakra and this inexplicable power... Who exactly are you?" the white light asked, its voice trembling.
If it had known that Yukika wielded a third power—magical energy—it would have been utterly shocked.
Yes, Yukika simultaneously mastered the powers of three worlds, making him a truly unique existence in the vast universe.
Yukika asked coldly, "Before I answer your question, tell me first—who are you?"
The white light shook its head. "My identity is extremely secret. You'd best not ask, or it will only bring harm to you. It's not wise."
"In that case," Yukika said calmly, "there's nothing more to discuss."
He had already made up his mind—no matter how elusive this white light was, today it wasn't going to leave here.
As his words fell, the power of the Blackwing Demon King, Ulquiorra, re-emerged in this world.
The white light let out a shriek, visibly terrified of this power!
Despite its lofty background, in the face of the Death God world's power, it was utterly insignificant, unable to resist.
In the end, the white light gradually disintegrated, crumbling inch by inch...
Even at the final moment, it refused to reveal its true identity.
Yukika keenly sensed that this white light might not be a living entity—it seemed more like an object devoid of emotions and thoughts.
Otherwise, given what he knew about the Ōtsutsuki clan—with their long lifespans and deep fear of death—they would never let themselves perish so easily.
After the white light vanished, the entire castle began to tremble violently, and massive changes erupted beneath the ground, causing the terrain to crack apart.
The castle started to collapse, and Yukika had already moved outside.
He watched as the fortress, built by the ancestors of the Ōtsutsuki clan, crumbled to ruin, the entire underground world sinking into darkness.
Without lingering, Yukika left the underground world and returned to Doomsday Valley.
He stepped out of End Valley.
Although the Ōtsutsuki clan's base on Earth had been completely destroyed by Yukika, he didn't believe the matter was truly over.
The Ōtsutsuki ancestral planet lay somewhere far off in the endless universe, its exact location unknown. Yet on Earth, members of the Ōtsutsuki clan still remained hidden.
As that tall clansman had mentioned earlier, there were nineteen clan members in total on Earth, though a few had already left the underground world.
Yukika also had his own suspicions about where they had gone and what their goals were.
It was all part of the plan to harvest the power of faith!
This plan was being carried out in secret—and it seemed it was gradually surfacing.
