Millennium fox demon Shu Jiao binds to the villain whitewashing system, shuttling through different worlds to make up for the original owners' regrets. In ancient times, she impersonated the tyrant's imperial grandmother, inducing Zhao Yuan with 'becoming an immortal' to reform government affairs and relieve the common people; in modern times, she used cross-spacetime technology to revitalize the country and change Chen Li's destiny; and she also incarnated as a fallen princess, maneuvering among various countries, rectifying the imperial court, and defying the heavens to change the fate for her mother and her old country. She appears lazy and shrewd, adept at coaxing, but actually cares for all living beings, resolves crises with wisdom, and gives those with notorious reputations a new lease on life.
