The Sword Awakens Across the Heavens: My Children and I Are All Invincible

This is a world where martial arts flourish and class advancement reigns supreme. First advancement: transcend the ordinary. Second: dominate the land. Third: stand above all. Fourth: defend the nation... Qin Feng was once a sword prodigy with astonishing talent, but his soul left his body and he spent twenty years an idiot. He was lovingly cared for by Lin Wan'er, a healing-class wife chosen for him by his parents, and together they had fraternal twins. Eighteen years later, on the day his children awakened their S-rank talents, the soul that had wandered beyond the heavens finally returned. Not only did his mind recover completely, he also activated the [Eternal High-Level Advancement Nurturing System]. From then on, the once-foolish father became an unparalleled Sword Sovereign, sweeping through the dungeons of the myriad heavens with his exceptionally gifted children. "Good kids, Dad will always be one advancement ahead of you."
