As the fragrance of the elixir wafted through the air, a heavenly phenomenon occurred, with a sky full of rosy clouds descending, amidst which countless butterfly shadows fluttered. This was a unique sight when a ninth grade elixir was refined in the Border Battlefield, which all Divinity Transformation cultivators who had spent time at the border knew.
It should be noted that in the Cultivation World, refining a ninth grade elixir would be accompanied by nine heavenly tribulations.
The Border Battlefield, being a minor world distinct from the heavenly laws of the Cultivation World, had suffered ravages from the Demon Clan earlier, and thus was exceptionally generous to cultivators. This was one of the reasons why such a selfish person like the ancestor of the Mo Family could be half-threatened, half-enticed by the Alliance Hierarch to stay at the Border Battlefield for a millennium.
This celestial phenomenon above.
Was not only witnessed by people outside the cave dwelling.
