"Master, it's not Big Brother's fault. He was protecting us," Yue'er quickly interjected, her voice filled with concern, afraid that the Azure Emperor might scold Hao'er.
The Azure Emperor glanced at her and said sternly, "Didn't I instruct you? Do not reveal your relationship to anyone outside. From this moment forward, do not call him 'brother.' Address him as 'Senior Brother' and Muchen as 'Second Senior Brother.'"
"Oh," Yue'er replied obediently, stealing a quick, apologetic glance at her two older siblings.
"Have you both remembered?" The Azure Emperor asked, his gaze now fixed on Hao'er and Muchen.
The two boys exchanged a brief look before replying in unison, "Yes, Master, disciple remembers."
