I Became the Top Miraculous Doctor in the World by Relying on Poisoning

The good-for-nothing bastard was poisoned by a strange poison and his life was hanging by a thread. However, he was picked up by an alcoholic miracle doctor and used the poison to nourish his body and counterattacked for ten years. Opening a medical clinic, fighting against imperial doctors, solving unjust cases, and shocking the capital with the sentence "If the treatment fails, I will refund the money, and if I die, I will lose." He used poison to save people, told the truth to break the situation, and eventually became a top-notch medical practitioner. This is not a miracle doctor, but a top-notch doctor.
