After the completion of the Grand Universe Palace, Empress Wu Zetian arranges for skilled craftsmen to utilize the technique of sunlight refraction, bringing the golden phoenix atop the palace to life as it spreads its wings and takes flight. This marvel also attracts a myriad of birds paying homage to the phoenix, leading the court officials to exclaim that Wu Zetian must be the divine daughter of the heavens, destined by fate itself. With this opportunity, Wu Zetian successfully ascends the throne. However, an unexpected turn of events unfolds as a celestial palace emerges in the sky, and from it descends a stone general who eventually destroys the golden phoenix. As people take it for an ill omen, Wu Zetian, in fury, urgently summons Di Renjie to the capital to thoroughly investigate the case. Once more, Di Renjie accepts the perilous mission, responding to each challenge with his unique wisdom and creativity, and unravels yet another extraordinary mystery!
