To protect his entire clan, the invincible ancestor Lu Xuan was set up by powerful figures from across the heavens. He vowed to guard the Heavenly Abyss for one hundred thousand years, standing alone against the demons from another realm. One hundred thousand years later, as his life force was nearly exhausted, he received a desperate plea from a descendant of his bloodline and learned that his family was facing annihilation. The entire Lu clan sacrificed their blood essence to prolong his life. Enraged, Lu Xuan shattered his oath, seized the demons' sacred medicine, broke through the seal, and returned. With unmatched power, he swept away his enemies, only to discover that the conspiracy from a hundred thousand years ago was far from over. A storm sweeping across countless worlds is once again gathering around him and the Lu family.
