Cultivating a Hundred Times to Become an Immortal

Wu Ju transmigrated into the body of a Voldemort who had sold himself into a mine for fifteen years to fund his younger brother's cultivation, and now had only three years left to live! All he could rely on was a status panel that couldn't add points and only provided feedback on his cultivation. But when he discovered that breakthroughs in his cultivation and skills could extend his lifespan, he started grinding hard, then grinding even harder, until a hundred thousand hours of grinding made him an immortal!
