My Lifespan Levels Up Martial Arts

Stricken with incurable tuberculosis, Lei Dao, a transmigrator, faced a grim countdown: a mere year left to live. Powerless and fading, he clung to a desperate hope – martial arts. But how could a dying man train for decades? Then, a miraculous power awakened: a glowing interface showing his dwindling lifespan. The terrifying twist? He could sacrifice those precious days to instantly level up any martial art, bypassing years of brutal training. He poured his borrowed time into external arts, gaining immense strength, yet his lungs still rotted. His last, desperate gamble? A mysterious 'health-preserving' technique from a dubious Daoist, promising longevity. Can Lei Dao truly level up his way out of death's grip, or will his ultimate martial art be his last breath?
