Ling Yu Xuan looked at Zhao Yang, her eyes involuntarily brimming with amazement!
He really had a way to cure Xu Yang's father's illness!
Xu Yang had not expected his father to fully recover; as long as his father's condition improved and his life was maintained, that would have been enough. However, he never imagined Zhao Yang would say it could be cured within a month!
How could this not fill him with unexpected joy?
This was lung disease, after all!
Xu Yang, gripped by emotion like someone clutching at a life-saving straw, nearly fell to his knees again just after standing up!
"I'm very confident, you just need to prepare the herbs according to the prescription. However, there are two herbs you won't be able to buy, I will send them to you by express delivery. Remember, besides the prescription I'm giving you, those two herbs must not be used anywhere else, nor let any traditional Chinese medicine practitioner see them, understand?" Zhao Yang instructed.
