The Northern Sea.
The sea lay in the far north, facing the distant Liao Territory. Cultivators from Great Li who wished to come here first had to enter the Eastern Sea.
After paying spirit treasures, rogue cultivators could use the shipping lanes controlled by several Immortal Sects to avoid Dragonkind territorial waters and skirt the immortal routes of Penglai. After a long passage through the chaotic seas, guarding against demonic ambushes along the way, they could reach the fringes of the Northern Sea.
Purple Mansion cultivators needed no such trouble. By entering the Great Void, they could head north at will, so long as they avoided Dragonkind territory.
Within the Great Void at the edge of the Northern Sea, a man in a deep-purple, splendid robe stood quietly atop violet thunder. A trace of violet aura flowed through his ink-black eyes as he surveyed the mortal world.
Before him stretched boundless deep-blue waters. To the west lay vast white plains, thick with moss in places, with several cities scattered across them. Cultivators rode the wind between them, drawing streaks of light across the sky.
Xu Xuan remained concealed within the Great Void. No one had noticed the arrival of this Purple Mansion Dragon King.
His divine ability stirred within him. The nature of shock thunder seemed to rise and cycle, and even his mysterious elephant showed signs of unfolding toward perfection. It was comparable to cultivating in the very heart of Heaven Pool.
"This sea truly is suited to cultivating shock thunder."
As a True Lord holding a fruit position, the mighty figure presiding over shock thunder had explicitly gathered its orthodox lineages and delineated a cultivation domain. Thus, the many cultivators practicing thunder-shock and firmament thunder in this sea could all partake of a little of its Dao intent.
