In a world where spiritual energy has recovered and mutated beasts roam, humanity stands on the brink of extinction, defended only by martial artists holding the line against invasions from foreign realms. Ning An, a transmigrator who arrived thirty years ago, faces a harsh reality: despite his hopes of becoming a prodigy, his aptitude is merely average. Now thirty years old and stuck at the peak of the second martial arts grade for six years, he has accepted a mediocre fate as a cautious counselor at Nanjiang Martial Arts University, prioritizing survival over glory.

However, on his thirtieth birthday, a mechanical voice finally announces that his 'Golden Finger' has come online. A system begins refreshing random superpowers for him, starting with 'Accumulate Strength,' a talent perfectly suited to shatter his long-standing bottleneck. Suddenly, the man who planned to lie flat finds himself breaking through realms with unprecedented speed.

As his cultivation surges from the third grade and beyond, Ning An must navigate the dangerous Myriad Races Battlefield, leverage his new unpredictable abilities, and rise from an underestimated veteran to a true pillar of the human race.
