Gu Zuo: Are you sick ah?
Gongyi Tianheng: You have medicine?
Gu Zuo: You are sick ah.
Gongyi Tianheng: If I say I'm sick, can you fix it?
Gu Zuo: If I say I have medicine, would you want it?
Gongyi Tianheng: However much you have is how much I want.
Gu Zuo: However much you want is how much I have.
Gongyi Tianheng: Then bring it all out.
Gu Zuo: …
Fearing death, Gu Zuo agreed to transmigrate but now he has to think of a way to survive. He has a golden finger called Medicine Refining System, but unfortunately, he doesn't have the ingredients needed to refine.
Gongyi Tianheng could not breakthrough; the main land's most noble house's eldest son's di descendant, he has outstanding IQ but his innate skill falls short.
The path of the apothecary is extremely difficult; he couldn't survive without a backer, but Gongyi Tianheng could mobilize plenty of ingredients.
Two people are sick and Gu Zuo has the medicine, therefore, the sick receive the medicine and he receives what he needs. Everyone is happy.
