The Five Elements lightning tribulation was a lightning tribulation interacting and resonating with the spiritual energies of heaven and earth's Five Elements, adding Five Elements transformations to the tribulation.
Lightning was formed from the yin and yang energies of heaven and earth. It contained the powers of life and death; amid destruction, it also held endless vitality. It was nature's most profound supreme method.
When lightning combined with Five Elements spiritual energy, it gave rise to infinite transformations. That was also the most terrifying aspect of the Five Elements lightning tribulation.
Gao Xian did not cultivate lightning arts, but through the Great Might Heavenly Dragon Law-Controlling Treasure Seal, he could command Divine Firmament lightning and Celestial Pivot Lightning. Moreover, within the Sword-Washing Pool, he had comprehended the sword intent of Divine Firmament thunderlight.
Having also undergone the tempering of nine lightning tribulations, he considered his understanding of lightning exceptionally profound.
Yet in two thousand years, he had never encountered lightning infused with Five Elements spiritual energy.
As he watched the tribulation lightning merge with metal-element power and descend from the sky, the lightning truly transformed into a colossal sword that split heaven and earth. Its power was violent, its light razor-sharp.
Through the Great Might Heavenly Dragon Law-Controlling Treasure Seal and his divine consciousness, Gao Xian observed and sensed this sword-sharp lightning from every level.
The essence wheel behind his head shone and revolved, resonating with the Army-Breaking Heavenly Sha Sword upon his soul. From the void, it guided boundless stellar power and transformed it into Wuji sword qi.
Gao Xian did not release the Wuji sword qi. The seventh-rank lightning tribulation would last fourteen days, perhaps even longer. He had to control his mana with precision and avoid any waste.
Fortunately, Sister Lan was presiding over the inner workings.
