After the founding of the nation, spirits aren't allowed to take human form. So what do you do if one does?
You outsource, of course!
As an exchange student, she's protected by the Heavenly Dao of both worlds. As long as she keeps her head down, she can live to a ripe old age.
But why does she keep running into poor little souls?
She just rescued someone whose Buddhist bone had been stolen, and then she came across someone whose natal sword had been taken before they were left for dead.
And there's also someone whose father doesn't care for them, whose mother doesn't love them, and whose limbs were broken before they were thrown out of the house.
She picked someone up to raise as a child, but somehow they ended up becoming a sect master.
Life's tough, so Fengfeng puts on a show to earn a living!
P.S. Fengfeng is a bear, not a queen bee. This exchange student from Huaxia is the child of the Heavenly Dao, so even the Heavenly Dao has to make way for them.
