Gu Xin no longer needs to manage the next night's service to the emperor. She was woken up before dawn and hasn't rested since; she hasn't had a break for ten consecutive hours.
However, she still remembered that she had promised Ah Yin to give her the antidote.
After tidying up a room in the South Lin delegation's accommodation, Gu Xin took the pair of silver needles that Lu Zheng had given her, which Dong Xue had brought.
She helped Ah Yin lie down and said, "Don't be nervous in a little while. It might hurt a bit when they insert the needle. You have to bear it and not move around."
Ayin nodded: "Princess Xinxin, don't worry, I am the most tolerant of pain. As long as I can get rid of the poison, no matter how painful it is, I can endure it."
Gu Xin believed A Yin's words, nodded, and without further ado, began to perform the diagnosis.
After the first injection, Ah Yin felt the pain, but she could bear it.
For the second and third injections, Ah Yin didn't have to grit her teeth.
By the fourth injection, she started to sweat slightly on her forehead.
Gu Xin smelled a strange odor, which must be coming from A Yin.
As Gu Xin administered the fifth acupuncture needle, she asked, "Is Yunheicao found in your Nanlin area?"
Ayin was taken aback: "Huh? Princess Xinxin, what kind of grass did you say? I didn't hear you clearly, could you say it again?"
Gu Xin inserted the needle, twirled it, and said, "Cloud Black Grass. It's a plant with leaves that look somewhat like clouds, but are pure black in color, about the size of a child's palm. It mostly grows in damp places, such as mountain streams and creeks."
After thinking for a moment, Ayin replied, "Princess Xinxin, I have seen this kind of grass in Nanlin. It was in the forest outside the capital of Nanlin."
Those who are trained from childhood to act as spies for the enemy are mostly intelligent and have good memories.
Ayin paused for a moment, then said, "However, I don't know what that grass is called, nor am I sure if it's the Cloud Black Grass that Princess Xinxin mentioned. But that grass is indeed about the size of a child's palm, pure black, and its leaves are like clouds. The reason I remember it is because the Second Princess saw it and found it strange. She wanted to pick it, but the guard stopped her, saying that it was a poisonous grass and that it was better not to pick it without a physician present."
After Ayin finished speaking, Gu Xin had already inserted the sixth needle. She picked up the needle to prepare for the seventh needle, and then asked, "What happened next? Did your second princess have the physician remove it?"
Ayin said, "The Second Princess had the physician pick it. As for what happened after that, I don't know. Since it was a poisonous herb, the Second Princess didn't pay much attention to it. The royal physician said that although the poisonous herb was toxic, it had a synergistic effect with certain herbs, and it might be used to make medicine to save lives. The Second Princess wasn't interested in that."
After Gu Xin finished inserting the seventh needle, she said, "I suspect that one of the poisons in your body contains this Cloud Black Grass. In our Great Zhou, it is called Cloud Black Grass. When it exists alone, its toxicity is not strong, but when it is mixed with certain herbs, as you said, in a synergistic or antagonistic way, it can exert its effects. A notable characteristic is that the sweat produced when poisoned by Cloud Black Grass has a peculiar smell, like food that has been left out for too long and gone bad."
Ah Yin: "..."
She instinctively wanted to move; she could feel herself sweating.
