Treasure Hunt at Kunlun's Summit, Season Five: Song Taizu, Part Two

Uncover the truth behind how Emperor Taizong of Song, Zhao Guangyi, came to the throne illegitimately.

On the night of "the candle shadows and the sound of an axe," Zhao Guangyi, the younger brother who had argued with Emperor Taizu of Song, Zhao Kuangyin, violated palace rules by staying inside the palace. In the dead of night, as Zhao Kuangyin was about to die, Empress Song sent someone to notify Zhao Defang, the son she had raised, hoping to secure an early advantage in the succession. But to her utter surprise, it was Zhao Guangyi who entered the emperor's bedchamber first. When he emerged, he announced that his elder brother had passed the throne to him.
