Of course, Jiang Xianrou was not stupid. She had also thought about the problem of the seller.
She had asked Jiang Yao to investigate, but he found nothing.
She only knew that the seller was a low-key 'old Chinese doctor' related to Wei Lou.
The Wei family was one of the top families in Beijing. She was not enough to compete with them with her current ability. However, she wouldn't be afraid of Wei Lou once she obtained the formula.
At that time, she would find the person who made the small pill and threaten him to seal his mouth. The small pill market would belong to her!
