>My eldest sister is the most talented woman in the capital, and she is also a master of poison. >She boiled medicine for me to drink every day, jokingly saying it was for my own good. >In the past ten years, I have never resisted and have been her medicine man. >Until the eve of her wedding, she fed the most poisonous wine to my lips: >"Sister, help my sister one last time." >I drank it all with a smile, but she suddenly vomited blood and fell to the ground. >Lean over and whisper in her ear: >"Sister, do you know why the poison you make always lacks the heat?" >"Because every time before I try the medicine, I take the antidote given by your husband." ---
