Who exactly is this woman?

"With my medicine," Sunshine responded, "I've encountered this disease on numerous occasions—"

Before Sunshine could finish, Luo Lina interjected, "Actually, you haven't."

"Oh, haven't I? My apologies, I must have discussed it with Luo Zhelan," Sunshine amended swiftly. "Regardless, I'm well-acquainted with it. I've conducted extensive research and developed a medication targeting the underlying mechanisms of accelerated aging at the cellular level. With my medicine, I've seen patients with the same condition extend their lives by several years, precisely as I've estimated. With my approach, I'm confident Old Madam Luo could live a minimum of 8 years—well, that is, of course, no unfortunate incidents happen."

Jiang Yue, grateful for Sunshine's assistance, couldn't help but suppress a twitch of her lips upon hearing her friend's final remarks. Did she really need to add that last bit?
