The Precocious Pea-Sized Physician

In my third life, just before becoming the empire's top councilor and returning to my original world... I was deceived by the emperor, lost my life, and reset back to age three. I refuse to reincarnate again! In my past life, my abilities blossomed, but the problem was I had no one to protect me. My trump card was my uncle, the greatest warrior, who was exiled to the East after contracting an incurable disease... ...my father. Treating him would give me a powerful ally! I hate it with a passion, but it's my last resort. I have no choice but to meet that despicable father who never once came looking for me. *“Father, this is a contract and a deal. I'll cure you if you become my guardian.”* Me... will I be able to return this time? (Source: KakaoPage, translated)
