The Luo Family has been providing medical services to the Moh Family for generations, so they have always been researching Miaojiang Gu Poison. Hongying's grandfather developed a medicine that suppresses the effects of the Gu Poison—it cannot completely detoxify, but it's currently the most effective medicine available.
However, the formula has always been in the hands of the Luo Family, and this is also the main reason why Hongying became Shiche's private doctor.
Upon hearing this, Hongying lowered her head, "I don't have the exact formula either. The medicines I have left were from my grandfather, and once they're used up, there won't be any more. We'll have to go back to the mountains to search..."
Whether her words were true or false, it was obvious that she wouldn't give it away.
Yunshen did not say anything more and nonchalantly hummed in response before striding out. Suddenly, Hongying called out to him, "Young Master Mu, aren't you going to ask me... about Lier's matter?"
