His dao sense inspected the sword. A spectacular view opened up before him. The Heart of the Non-Verse, the antithesis of purity, contained a full world with its own set of laws.
He witnessed a world filled with countless living souls of Kitsune. They were numerous, amounting in the billions, and they underwent life normally.
In the world, when his sense entered this world, he felt like god looking upon all creation. A literal god looking inside from outside a self-contained world. It had a star, planets, and moons.
"..." He grew silent. These souls that existed in this world were kitsune. However, he was confused. How could a world filled with impurity contain a world.
"A miniature universe?" As he thought about how irrationally incoherent this was, he pondered more. If this was a miniature universe, then it needed two polar opposites to sustain itself.
He turned towards the rock and observed the grail that revealed a light of purity. "Another heart! Right! Of course!" His eyes brightened with intense enlightenment.
The two hearts belonged to the same universe, with them working together, they created two universes that were self-contained. He grasped the rock that held the grail and clenched. It shattered instantly, revealing the pure white grail that emitted purity of the highest. He felt a familiarity to it like no other.
In a way, this was a piece of his parent. His gaze softened. With a light touch, he swept the grail into his palm. The knights who saw this went crazy, their eyes and voices strained to their limits. If they weren't suppressed by heavenly laws overturned by Yan Zaizen, they would've recklessly charged forth to reclaim the grail.
Yan Zaizen ignored their intense reactions, "There is another world inside here as well. Indeed, two must exist. The souls here...are of those knights?" His words came off as a question because when he saw the souls shapes and aura, they weren't similar to the knights.
They looked like dwarves. They were short and stubby, waddling with short legs and chubby fingers.
However, the knights were fierce warriors that towered several meters. He inspected them more thoroughly and found that the number of individuals in this world exceeded trillions.
He deeply frowned.
Then, he abruptly laughed. "You stupid, stupid idiots!" He couldn't stop laughing as he realized what had happened.
"I see! They were chosen by the grail, receiving its blessing and their souls were pinned to this universe. If they die, they'll be reincarnated here, receiving everlasting life until the eventual collapse of this universe. But the number within was reaching maximum capacity, no new souls could enter - prohibited by the universe itself for self-preservation.
"To overcome this, you tried to connect with the impure universe! When you did, you tainted yourself. How hilarious! Do you think regaining the grail will return your race back to where it was? No! Your entire soul line has been tainted." He quietly said, but his words echoed in the voices of each and every race.
"As for you kitsune, I don't know how you obtained the right to exist in the impure universe, but now you can't even cultivate normally! While I am curious of your story, I can make some conjectures, and I find it rather boring." Yan Zaizen stated as he sighed heavily.
"Your entire soul lines have been connected with the universe. You no longer belong here, so I'll send you all to your world. Until the universe collapses, you can exist." His words were cold as he gripped the black arming sword forcefully.
His Non-Entity physique connected with both hearts. Within one hand, the unholy sword, in the other, the holy grail.
"Expand!" He commanded. His heavenly might integrated into both universes, slightly expanding it. Then, with a wave, the kitsune and knights were drawn into the two objects as if they were returning to where they belonged. The black knights to a universe of purity. The kitsune to a universe of impurity.
As he did, the overturned heavens regained their normalcy.
"How foolish!" He sighed emotionally. While he may have seemed cold performing these actions, locking them into a universe, he had to. The reason was that they couldn't exist in this world.
He had to take the grail and the sword with him, and if he did, they would collapse entirely into death. As for why, his instincts told him so. Therefore, while selfish, he had to.
While he could choose to recombine the two objects, this wouldn't solve their plights. Their entire existences were tainted with another universe's laws, and they couldn't cultivate normally. It was just like the Oneuli Empire's Prince.
"When I become stronger, I'll separate all of your souls from the hearts, return you to the Non-Verse, and give you all a second life as restitution. In fact, if it wasn't because of your souls, the two universes stability likely would've collapsed by now." As he recalled the various states, he realized there was more to this than he could take in at the moment.
Unfortunately, he had his own deadline. He couldn't waste anymore time.
It was time to leave the Heavenly Origin Grounds and take a visit to hell. The two objects were directly stored in his Meteor Ring.
Just as he was thinking of events, a ripple appeared behind him. Yri exited the spatial ripple, her eyes were filled with vigilance. "What the hell was that scorching light? I felt as if my entire face was melting!" She started to wildly curse as she observed the empty village and castle that floated lifelessly in the sky.
"Nothing. We should go," Yan Zaizen said indifferently.
"What? You rushed here from so far and yet you want to leave? Well, I'll tell you this, I won't let you drag me around! Unless…" her eyes sparkled as indecent thoughts emerged in her mind.
Yan Zaizen sighed. This woman truly wanted to dual cultivate for this Dao Heart. If it wasn't for the various factors that could happen if he did, perhaps he would've long since performed the deed to repay his debt.
"Let's go!" He said, leaping into the sky and entering the spatial void. Yri pouted and followed along while muttering various curses.
