"Eldest Miss, are Qing Hu and Qing Liu really poisoned?" asked Qing Mama in disbelief.
"Yes. They are poisoned with the Yin Yang Poison, which is colorless and tasteless. If it is used in isolation, it is not effective. However, if it is used on two people who not only interact with each other all the time but also eat and sleep together, its potency intensifies. When they die, they will die without exhibiting any symptoms. Even if a physician were to check on them, he would not be able to determine the cause of death."
Ye Jiuge withdrew her hand. When she noticed how Qing Mama and the two maids' faces were pale with shock, she consoled them, "Don't worry. Although this poison is powerful, it's not difficult to produce an antidote. Tomorrow, I will purchase two sets of medicine based on a prescription I have written and alchemize them. Everything will be fine."
