Immortal King's Eternal Reign: Ten Thousand Years of Supreme Cultivation

What happens when immortality meets supreme power? After rising to Quasi-Emperor in just three centuries—the fastest ascension in history—our transmigrated hero faces an impossible choice. Bound by brotherhood to his rival, the Holy Son of Ziwei, they've conquered forbidden zones and claimed immortal legacies together. But tradition demands only one Great Emperor per era. Just as their fated battle looms, a Divine Choice System awakens, granting the ultimate prize: the Dao Fruit of Longevity. With infinite time and unmatched talent, he'll transcend the very limits of cultivation itself.
