After Practicing for Thousands of Years, My Father Was Raised as an Immortal Emperor

Zhang Haojun unexpectedly failed the qualification examination for alchemist. Zhang Haojun was scolded by his classmates and framed by the conspiracy. He had no choice but to agree to go to the black medicine factory to refine medicine and repay the debt. Before leaving, he gave medicine to his vegetative father, but the medicine refining system awakened: the stronger the father, the more valuable the reward. From then on, he worked hard to cultivate his father's status. Pills are sold by the pound, materials are weighed by the ton, clowns are stepping on them, beauties are surrounded by clouds, and the world is almost at your fingertips. The only problem is... Dad's cultivation level is growing so fast that Zhang Haojun can't keep up. It's unmistakable, the biggest winner is Dad.
