In the peerless Tangmen, Huo and Orange have a son named Xu. It was at this critical moment that Xu Tianran, the emperor of Sun Moon Empire, forced himself to borrow seeds from the prince of Sun Moon Empire and gave birth to the purest crown prince of Sun Moon Empire. Orange countered, secretly borrowed seeds while Huo was unconscious, and gave birth to Xu.

Because Tangzi was asked by Tang San to threaten the lives of her mother and son, she decided to keep this secret until she died. Later, when Huo wanted to take Xu away, Tangzi lost his voice and told the truth.

The legend of the Dragon King mentioned it as "the wise king of a generation", but its name has not been seen.
