I can extract side effects

Wei Kang inherited a pharmaceutical company that was about to go bankrupt.
The company spent huge sums of money to research and develop new drugs but failed, peers suppressed the bank to press for loans, both parents died in a car accident, and he suddenly contracted cancer.
Fortunately, he awakened a medical black technology system that can extract certain side effects from drugs to make new drugs.
The new drug that the company has just failed to develop contains a 0.01% side effect that effectively inhibits cancer cells.
So he took the scrapped prescription and started to extract the side effects.
Antihypertensive drugs do not lower blood pressure at all, but have the side effect of relieving pain, extract side effects, and become the most effective painkillers.
Antipyretics have no effect at all, instead of lowering the body temperature, the metabolism is accelerated, and the side effects are extracted, becoming a popular weight-loss drug.
Eye drops are too irritating, and also cause hair follicles to grow thicker and have side effects, making them the most popular hair tonic.
Antithrombotic drug research and development failed, the side effect is to enhance human immunity?
Extract, extract, extract! ! !
Wei Kang not only completely cured his terminal illness, but also became the greatest god of medicine in human history.
