Ye Mei's exclamation caused Sun Zhian's complexion to drastically change.
Ye Tianchang, however, indifferently reached out his hand and took the prescription for Ye Fei's medicine from Ye Mei.
After glancing over it lightly, he then said in a deep voice, "I have never seen this prescription before; it's completely unheard of. In all of history, you're probably the first person daring to treat someone with such a prescription."
Ye Tianchang's words made Sun Zhian's face look even worse.
He furrowed his brow, anxiously asking, "Brother Ye Fei, can this prescription really cure my mother?"
Ye Fei sighed helplessly and gently shook his head.
"I only have sixty percent confidence."
Upon hearing this, Sun Zhian's expression turned odd.
Sixty percent confidence was indeed a huge risk.
After all, should it fail, his mother would probably be killed on the spot.
