Fang Ling'er stared at Fang Yu who was still in a daze, seeing the look in her cousin's eyes was enough to make her elated. Clearly, Fang Yu had no idea what she was doing. After all, this disease was kept a secret and not many people knew about the plague down south.
The Potioneering Guild and the Guild of Artifacts actually keep it a secret to avoid mass panic. However, Fang Ling'er was different. She had been close to Xiawen Dong and she heard a few things from the man's mouth especially when he was drunk. She knew about this plague and she also knew that the Potioneering Guild are trying their best to find a cure.
Therefore, Fang Ling'er tried her best to talk to one of the people in charge of this matter and gave them a very important herb that she got from her husband. In return, they agreed to give her the formula for the cure so she could study and improve its effectiveness.
