On the 19th day of the twelfth lunar month, the sixty-fifth birthday of Master Yu of Yu Family Manor in Dazhong Capital—a renowned physician known as the "Herbal Sage"—was being celebrated. By the 18th, guests began to arrive steadily, and the manor was bustling with visitors. Yun Rao slightly adjusted her appearance, prepared a substantial gift, and carried a request card she had snatched from Su Yan, presenting herself as Lady Su Ran, the senior daughter of Ba Fang Pavilion, as an honored guest for the celebration. Though Ba Fang Pavilion was a well-known intelligence network in the martial arts world, and Yu Family Manor stood as a distinguished medical dynasty in the capital, their interaction had been limited over time. Lady Su Ran—known primarily by name, yet never personally met—had thus remained unfamiliar to the Yu family. The fact that Yu Manor had personally issued an invitation was notable; however, due to Ba Fang Pavilion's prominent standing among the martial circles, Yun Rao’s arrival as Lady Su Ran did not raise any suspicion in Master Yu’s mind.
