I Begin My Path to Immortality by Butchering Fish

After transmigrating to the cultivation world, Chen Anqing spent ten years as the lowest-ranking fish butcher in the West Market, while piling up a mountain of “longevity loans.” Then one day, as he was slaughtering a carp, a glowing screen suddenly appeared before his eyes: 【Valid kill detected: carp (mortal creature)】 【Extracting vital energy...】 【Extraction complete. Vital energy gained: 0.01】 【System function: Kill living creatures to plunder vital energy. The amount gained depends on the creature's strength and the method of killing.】 From that moment on, his whole life took a different turn: Others fought to the death over treasures in secret realms, while he killed chickens and geese and steadily built up his vital energy; Others shut themselves away to cultivate, racing against time, while he pulled weeds and hoed the garden behind his house, steadily increasing his cultivation; Others risked their lives for a single demon core, while he looked at a demon beast, swung his blade, and collected another walking bundle of experience points. From slaughtering fish and pulling weeds to killing cultivators, everything became fuel for his path to the Great Dao. Many years later, Chen Anqing had attained carefree longevity in the perilous Immortal Realm. At his fish stall in the West Market, he sighed, “I only meant to slaughter a fish. How did I end up paving the way to invincibility...?”
