Xu Ping'an gasped for breath. The wounds on his body rapidly healed under the nourishment of Life Force, while the Golden Core Embryo in his sea of qi had condensed like jade, its five-colored halo drawn inward as faint dark radiance flowed within.
Yet just as he caught his breath, the Tribulation Clouds changed again.
This time, no tangible entity emerged from the clouds. Instead, a boundless five-colored lightning rain poured down.

Thunder pearls containing the power of the five elements cascaded from the Tribulation Clouds. Each varied in size and flashed with lightning of different colors. They fell as densely as a sudden downpour, covering an area more than ten times larger than before and forming a surging Thunder Sea.
Even more terrifying, these thunder pearls could not only ravage the flesh, but also erode spiritual power and the soul.

Li Wudao's expression darkened. "The fourth tribulation lightning: the Five-Element Lightning Sea!"
Xu Changqing's expression shifted slightly as he thought, This is even more terrifying than when I underwent tribulation transcendence!
When he underwent tribulation transcendence, it had merely been five-colored lightning rain.
There had been Supreme-Yang Metal Lightning Rain that melted spiritual artifacts,
Withered-Bloom Wood Lightning Rain that corroded and severed Spiritual Roots,
Profound-Yin Water Lightning Rain that sealed and froze the soul,
Burning-Flame Fire Lightning Rain that burned consciousness,
and Suppressive Earth Lightning Rain that ravaged the body. The five lightning rains combined and poured down in a torrential deluge.
But his younger son's situation was even worse than he had imagined. The lightning rain had evolved into a Thunder Sea,
