Mingyue falls from the pinnacle of imperial glory to the desolate Cold Palace. During a bitter winter, she is humiliated while begging for charcoal and stumbles through the snow. In a corner, she rescues a dying crimson bird. For seven years, she cares for it devotedly, only to discover that the bird feeds exclusively on deadly poisonous parasites. When an elderly divine physician is ordered to examine it, his silver needle turns red-hot as soon as it approaches the cage, leaving him deathly pale and drenched in sweat. Mingyue calmly reveals the truth, prompting the physician to ask in astonishment where the bird came from. The crimson bird's extraordinary nature quietly stirs hidden secrets within the imperial palace, planting a seed of hope for Mingyue in her desperate plight.
