The Song Family having received favor from Song Zhiyuan, the Lu Family wisely brought a gift of thanks along. Accompanying the gift was a secret formula—a recipe for Yangrong Pills—from the Lu Family, marking both repayment and a gesture of alliance.
After all, though the Lu Family's master physician has retired, they are not withdrawing from the power center within the capital, needing to secure alliances, and who better to rely on than Prime Minister Song, who is steadfast and trustworthy?
"This master physician from Lu is truly generous." Song Ci, reviewing the formula chart, raised an eyebrow and said to Song Zhiyuan, "Yangrong Pills were always exclusively sold at their family clinic, serving as a major source of income. Now that they've sent it over, with our family's pharmacy producing and exporting it, the profits will be substantial indeed."
