The existence of the Phoenix Girl was something the previous King told him about with his last breath. It had been the imperial family's secret, something which was only known to the imperial family.
It was actually a secret open only for the kings of different generations, but this secret had been on hold for too long, and what the King had told him was too limited for him to dig deeper. All he knew was that the Phoenix Girl existed, and that there were other more ferocious beings living on the continent.
However, it was not clear when the Phoenix Girl would arrive.
In the past generations of kings, the King had always believed that he was lucky enough to know who the Phoenix Girl was, when he was on the throne.
Normally the King should marry the Phoenix Girl when she first reaches marrying age, but when the Phoenix Girl was found, she had already become Lord Ling's Princess Consort. So he had to drop this idea.
