Corporate slave Chen Fangzi died of overwork, missed drinking Meng Po's soup during reincarnation, and was reborn as Lin Shiliu, a girl on a garbage star. Every day she oscillates between life and death, holding only foul-smelling expired nutrient solution. Accidentally discovering that waste plants in the eyes of others are all precious medicinal herbs in hers. Thus, full of resentment, she resolves to seize the opportunity, refine medicine on the barren garbage star, rely on her special ability to study wholeheartedly, and forge ahead toward the goal of the strongest interstellar pharmacist.
