I set the story in the anime when there were no unicorns in Fang Country. At that time, Huihou only killed the emperor and did not kill the unicorns.
There was no Qilin in Fang Country until that day when the female monster was born. She ran to the tree and gently stroked the fruit on the tree, murmuring: "Fenglin."
When Feng Lin chooses the king determined by heaven, it means that the king of Fang Kingdom can no longer sit on the throne and enjoy all this.
Feng Lin: I am willing to find my king. I want to make Fang Country more prosperous than Yan Country.
Leer: I am willing to go on with my Qilin and move towards a new world.
Ps: Leer and Lejun have nothing to do with each other. If anything, they traveled together later. Please forgive me for writing this based on anime.
