Sisi was very angry. Her storytelling had been rudely interrupted just when the narrative reached the part about the servant girl who could change her appearance, and her beloved "immortal brother" had been snatched away.
The infuriating part was that she really couldn't follow them, not even as Zhao Changhe's supposed servant.
Her disguise as a Tang family servant had been exposed long ago—the real servants had been rescued from the firewood shed after starving for two days. If it hadn't been for Zhao Changhe's warning, they might have really starved to death. The Tang family didn't trouble her, likely because they thought she had been of some help. How could they possibly let someone of unknown origin stick around to listen to the "serious business discussions" between Tang Wanju and Zhao Changhe?
