Synopsis：During the inauguration of the Hall of Ten Thousand Gods, Wu Zetian arranged for skilled artisans to use the refraction of sunlight to make the golden phoenix atop the hall come to life, spreading its wings and soaring, while also summoning a miraculous spectacle of thousands of birds paying homage to the phoenix. The court officials exclaimed that Wu Zetian was a divine woman of heaven, destined by fate, and she seized this perfect opportunity to ascend the throne smoothly. However, the situation suddenly changed: a heavenly palace appeared in the sky, and a stone deity descended to smash the golden phoenix, turning the auspicious sign into a bad omen. Enraged, Wu Zetian urgently summoned Di Renjie back to the capital to investigate the case. Once again entrusted with a critical mission, Di Renjie used his unique wisdom and creativity to solve yet another extraordinary mystery.
