Paper Cranes (слэш)

One thousand paper cranes.
That’s how many it cost to make a wish.
Once, Lan Zhan sat at his mother's knee, listening as she taught him the secrets to a cultivation so different from anything else he knew.
Now, the ceiling bristled with paper wings, in even rows draped gracefully along the dark wooden beams, and every single crane called out for one thing.
‘Bring him back. Please, bring him back to me, happy and whole.’
