Confucius would have said, that, to know the extent of ones ignorance one should face the blue dragon.
Well we found out the depth of our ignorance the day that the blue dragon and her helpers came. For we had no answers to her and the devilry. Any attempt to greet the dragon, was met with a breath of blue gas which poisoned those who it touched. So we tried sending chariots loaded with the powder of black dead but that had no effect on the blue dragon. She just sent out more and more blue gas, and the people fell before it.
