I can extract side effects

Wei Kang inherited a pharmaceutical company on the verge of bankruptcy. The firm had invested vast amounts in the research and development of new medications but faced failures, with rivals pushing banks to demand repayments. Compounding his woes, both of his parents tragically died in a car accident, and he was suddenly diagnosed with cancer. Fortunately, he awakened a medical black technology system capable of extracting specific side effects from drugs to create new medications. The recently failed drug development contained a 0.01% side effect that effectively inhibited cancer cells. Thus, he utilized the discarded prescription to begin extracting these side effects. Antihypertensive drugs, which did not lower blood pressure, surprisingly had the side effect of alleviating pain, leading to the creation of the most effective painkillers. Antipyretics proved ineffective at lowering body temperature but accelerated metabolism, and upon extracting the side effects, they transformed into a popular weight-loss drug. Eye drops, known for their irritation, also had the side effect of promoting thicker hair growth, making them the most sought-after hair tonic. Development of an antithrombotic drug failed, yet the side effect boosted human immunity? Extract, extract, extract! Wei Kang not only cured his terminal illness but also emerged as the greatest medical genius in human history.
