Every drop of sweat from his underlings doubles his power—literally. Reborn in the Naruto world on the brink of the Second Great Ninja War, Qixing Feiyu discovers his cheat ability: the Hard Work System. The harder his subordinates train, the stronger he becomes. With this parasitic power, he's determined to exploit every ounce of effort around him to climb to the top. "Work harder! Your blood and tears are my stepping stones to ruling the ninja world!" A ruthless climb where others grind while he reaps all the rewards.
