Inside the Ten Thousand Arts Martial Training Tower in the Void Realm.
Lu Zhen stood amid a simulated starry sky.
He was comprehending the profound mysteries of law within the "Polar Night Meteor Sword."
This upper-tier third-grade dark-element killing art had four levels.
The first level, "Silent Shadow," required the Dark Law to reach the "nascent branch" stage before one could begin.
Once mastered, the body became a dark shadow and the sword struck without a sound, powerful enough to tear through the Great Dao law defenses of an early Fifth Realm "Initial Accumulation" mighty cultivator.
The second level, "Polar Night Plunder," required the Dark Law to form a complete "Great Dao branch."
With a single sword strike, polar night descended, stripping away the five senses and divine sense; even a mid-Fifth Realm "Dao Evolution" expert who had fused two Great Dao branches could meet a bitter end with the slightest carelessness.
The third level, "Annihilation Meteor," was even more demanding, requiring one to reach mid-Fifth Realm "Dao Evolution" and fuse two Great Dao branches before it could be unleashed.
One sword strike brought annihilation and collapsed the void, enough to utterly suppress mighty cultivators of the same level.
The fourth level, "Ninefold Darkness Return to the Ruins," was an ultimate killing move aimed squarely at the late Fifth Realm "Dao Domain" stage.
It required the fusion of more than five Great Dao branches and the formation of a polar night Dao Domain; wherever the sword light passed, all arts fell silent, striking fear even into a pinnacle existence of the Great Wilderness like Divine Duke Wuji.
What an overbearing sword art, Lu Zhen marveled inwardly.
He closed his eyes and followed the art's guidance, capturing the Dark Law drifting through the starry sky.
Cold, fathomless, capable of devouring souls.
