Alone beneath the lamplight he said quietly, "The matter of the goose coops you asked about is a matter of the present ruler's lawlessness. What do you want to keep asking about it for?"
無道 wú dào is the heaviest political word in classical Chinese: a ruler who is 無道 has forfeited the mandate, and saying so of a living king is treason. The courier chief has cleared the room, turned down his voice and used it anyway.
Tripitaka said, "In what way lawless?
為 is wéi here, the copular one — in what does the lawlessness consist — and not the wèi of purpose. The chapter uses both, and fourteen of its nineteen take this reading.
"You must make it clear to me, and then I can set my mind at rest."
放心 fàng xīn is still the everyday phrase for setting the mind at ease, and there is a grim joke buried in it. Tripitaka says he needs the truth in order to rest. He will not sleep for the rest of the chapter.
The staging is careful: the room emptied, one lamp, a voice pitched low. What follows is the longest single speech in the chapter, and the novel has spent four passages making sure the reader understands what it costs the speaker to give it.
The word he chooses is the decisive one. To call a reigning king lawless is not a complaint about policy — it is the formula that says heaven has withdrawn its warrant. A market poem two hundred characters ago certified this reign with the phrase about the river running clear. The same chapter now has an official of that government saying the opposite in a whisper.
