After breaking through to the Nascent Soul Late Stage, advancing further to the Nascent Soul Peak would require not only more resources and spiritual energy, but also a deeper comprehension of the laws.
The time required would be far greater than what it had taken to break through to the Nascent Soul Late Stage. Cultivation was of little use for the time being.
Having obtained the Gui Shui Divine Lightning, a spell he had once dreamed of obtaining, he naturally had to study it thoroughly.
He had once cultivated the Wutu Divine Thunder to the fourth level. Now that he was cultivating the Gui Shui Divine Lightning, he at least had some foundation.
With Nascent Soul Late Stage cultivation, cultivating a Peak Fourth-order spell naturally posed no difficulty.
It took him only five days to cultivate the Gui Shui Divine Lightning to the ninth level.
The Gui Shui Divine Lightning he cultivated was not suited for frontal combat, but it excelled at stabbing people in the back.
He condensed his Water Spiritual Power into a spiritual power sphere slightly over three inches in diameter. The sphere was nearly colorless and transparent.
Without prior preparation, it was difficult to spot with the naked eye.
Moreover, his Water Spiritual Power carried the divine-sense-blocking effect of the Gui Water Nether Flame.
If he fought someone at sea, he could even conceal the Gui Shui Divine Lightning beneath the water.
Without a special divine ability or secret art, it would be extremely difficult to discover this method.
He threw the Gui Shui Divine Lightning in his hand at a rock more than a foot in diameter within the cave mansion. The entire bolt directly seeped into the rock.
In an instant, the rock split in half, while its interior shattered into gravel.
