Nine at the beginning means:

You let your magic tortoise go,
And look at me with the corners of your mouth drooping.
Misfortune.


The magic tortoise is a creature possessed of such supernatural powers that it lives on air and needs no earthly nourishment. The image means that a man fitted by nature and position to live freely and independently renounces this self-reliance and instead looks with envy and discontent at others who are outwardly in better circumstances. But such base envy only arouses derision and contempt in those others. This has bad results.
