She Actually Noticed It

"Yes. Lil' Lin, take your brother and sister to rest first," Gu Qingxue said.

Gu Lin nodded obediently. He carried his drowsy sister with Dumby and walked quickly toward the south wing.

Gu Qingxue sat opposite Rong Zhan. "The poison that young master was poisoned with is called Yanqiluo. It's a rare poisonous flower that can only be nurtured after decades."

"I've never heard of this kind of poison," Rong Zhan said thoughtfully as he tapped the table with his fingertip.

"This kind of flower is indeed rare. By chance, I've read an ancient book that recorded this kind of poisonous flower. People who are poisoned by this kind of poison will die from the poison within a short period of time, and they will become delirious like a crazy demon. Last time, when I checked Young Master's pulse, I could tell that Young Master had a high level of internal energy. I think he must have been using his internal energy to suppress the poison," Gu Qingxue said firmly.
