Gu Yanfei took the teapot from Wei Jiaoniang's hand and poured barley tea for the two of them. The unique burnt fragrance of barley tea spread with the steam.
Gu Yanfei drank tea leisurely and looked in the direction of the Myriad Herb Hall.
The so-called "penicillin powder" sold in this medical center was clearly penicillin, which was only recorded in the Emperor Taizu's Handbook. The Emperor had long asked the Embroidered Uniform Guards to turn over the foundation of this medical center and investigate the mastermind clearly.
Gu Yanfei naturally found out about this from Chu Yi.
Wei Jiaoniang was still immersed in the shock of this news. She muttered, "It's actually Gu Yunrong."
As the two of them whispered, the tea guests in the tea shop were still arguing non-stop. Some felt that the owner of the Myriad Herb Hall was telling the truth, and more people felt that Second Lady Gu was kind and wouldn't harm anyone.
