In Yaoding City, discarded waste pills littered everywhere hide unexhausted medicinal properties. Relying not on alchemy talent but on extraordinary senses, sanitation engineer Jiuzhang teams up with frustrated pharmacy apprentice Bai Zhiqiu to explore waste pill recycling technology from scratch. Overcoming heavy obstructions from Purple Furnace Alliance Chief Alchemist Nangong Qihuang, they break through supply blockades, medicine scarcity crises, and ancient elixir storehouse catastrophes, overthrowing old industry bad habits and establishing a brand new classified, traceable disposal system for medicinal waste in the cultivation world.
