Su Binglan needed another herb to do it, but there were no pharmacies in town that sold it, and she could not find it when she went to the back of the mountain. With that, she had to delay her father's treatment.
Moreover, she needed a lot of money to buy herbs and build surgical tools, so she thought of saving money before surgery. Now that her family's businesses were doing well, she could finally perform the surgery.
She was now mentioning these things to the Su family because Su Fengmao wanted to help in the shops, even though it was inconvenient for him.
Su Binglan's heart was uneasy when she saw the anxious look in her father's eyes. Hence, she said these things out loud to cheer everyone up.
Indeed, Su Fengmao was thrilled. His eyes reddened as he said, "If you say you can do it, I will believe you."
