No one could say for certain what awaited on the other end of the Void Corridor.
But there was a strong possibility it led to the Mo Battlefield. Should Yang Kai venture deep into it, his chances of survival would be slim—one death among nine, at best.
Even if he somehow made it out alive, he would never have the chance to return to these Three Thousand Worlds in this lifetime. That was precisely why the Mo Sha Divine Lord had been so generous as to pass on the cultivation methods for the two great Eye Arts.
Otherwise, how could the Myriad Demon Heaven's closely guarded secret ever be so readily leaked?
Upon returning to the Lingxiao Palace stronghold, Yang Kai immediately announced his seclusion.
Just as the Mo Sha Divine Lord had said, his remaining time was running short. The Mo Battlefield was perilous beyond measure, and it was already too late to attempt a breakthrough in cultivation. But if he could deepen his mastery of the two Eye Arts, they might prove useful in some critical moment.
Though the women did not know the purpose of his seclusion, they all understood.
Moreover, the days they had spent together had already filled them with contentment.
The jade slip contained the cultivation methods for both Eye Arts, along with descriptions of the supreme might each could achieve when perfected.
The World-Destroying Demon Eye and the Infernal Black Pupil—one offensive, one supportive.
If truly perfected to the utmost, the World-Destroying Demon Eye was capable of piercing through every illusion in existence. Previously, in order to break the Super Grand Array enveloping the Black Domain, the Blessed Realms had mobilized countless manpower to mine star cores, thereby weakening the array's power.
But at the same time, there had been another group responsible for cracking the countless smaller arrays scattered throughout the Black Domain.
These arrays, like the mining star cores, were all part of the Super Grand Array.
And that group had been led primarily by cultivators from the Myriad Demon Heaven, with numerous formation masters assisting. Within the Myriad Demon Heaven, those who had cultivated the World-Destroying Demon Eye—High-Rank Open Heaven cultivators all—could see the flaws in many arrays with crystal clarity under their dharma eyes, greatly reducing the time needed to dismantle them and boosting efficiency.
The most critical array outside the prison cage was one Yang Kai had once observed by activating the World-Destroying Demon Eye himself. He had known it to be extraordinarily dangerous, but could find no way around it. In the end, several grandmasters of formation arts had to join forces, channeling their power to carve out a passage that delivered him into the heart of the cage.
During the hundred years Yang Kai had been trapped inside the cage, it was the Mo Sha Divine Lord himself who had taken action and discovered the flaw in the array surrounding the cage, ultimately succeeding in dismantling it entirely.
He was no student of formation arts. What he had relied upon was none other than the World-Destroying Demon Eye's power to see through illusion.
Yet even with his formidable cultivation at the Eighth-Rank Open Heaven stage, he had still not managed to cultivate the World-Destroying Demon Eye to its highest realm.
According to the jade slip, if one could truly cultivate the World-Destroying Demon Eye to its absolute peak, it would even be capable of seeing through the barriers of time and space, granting foresight—glimpses of events yet to unfold.
In the entire recorded history of the Myriad Demon Heaven, no one had ever cultivated the World-Destroying Demon Eye to that realm. Whether such a realm even existed was something the Myriad Demon Heaven itself could not confirm—mere speculation.
That was rather inconceivable. Yang Kai did not presume to achieve a feat that countless generations of Myriad Demon Heaven powerhouses had failed to accomplish. He merely wished to elevate his Eye Arts to a more formidable level, and that alone would satisfy him.
The World-Destroying Demon Eye held no lethal force. Its primary function was intimidation and support.
In contrast, the Infernal Black Pupil was an offensive technique of tremendous destructive power. Yang Kai had once used this secret art himself, so he understood its might intimately.
Under the Infernal Black Pupil, all things perished into silence. The world plunged into darkness. The enemy targeted by this secret art would often have no inkling of it before the technique had already taken hold. Once unleashed, it could strip the target of every last sense.
In battle, the loss of one's senses was a guaranteed path to peril.
Days passed one after another.
The Lingxiao Palace stronghold remained peaceful, and no one disturbed Yang Kai's seclusion lightly.
Then one day, a streak of light shot in from beyond the sky, landing directly.
Sensing the disturbance, the Lingxiao Palace cultivators emerged one after another to investigate. Xue Yue stepped forward and dropped to one knee in salute. "Master!"
The newcomer was none other than the Six Wood Divine Lord, though his expression was grave—something had clearly happened.
A heavy weight settled over the hearts of the Lingxiao Palace crowd.
Peaceful as these days had been, what was destined to come had come at last.
"It's time to call him out of seclusion!" the Six Wood Divine Lord said, looking at Xue Yue.
Xue Yue pressed her lips together, nodded, and turned to leave.
Yu Rumeng stepped forward and asked, "Senior, is it time?"
The Six Wood Divine Lord shook his head. "I can't say for certain. But he needs to go over there and take up position, just in case."
It had been roughly four or five months since Yang Kai had returned from the other side of the Void Corridor. In that time, the ancient seal's power had been steadily dissipating. Once it dissipated entirely, the Void Corridor would fully take shape, linking the two void locations.
In just the last few days, the speed of the ancient seal's decay had noticeably accelerated. The Divine Lords stationed on site did not dare let their guard down, so the Six Wood Divine Lord had come to fetch Yang Kai.
