Pilgrim said, "We are passing through the Kingdom of Bhikshu, and the king of it is lawless. He listens to a fiend, and would take the hearts and livers of small boys for a medicine-guide, in hopes of long life.
長 is cháng here, long — not the zhǎng of seniority that this character takes twenty-four times in the chapter. Wukong states the case in one sentence, and he uses the courier chief's own word for the king: 無道, lawless.
"My master cannot bear it at all, and wishes to save the living and destroy the monster.
救生滅怪 — save the living, wipe out the fiend. Wukong attributes the whole enterprise to Tripitaka, which is both generous and true: the master wept, and this is what came of it.
Wukong is filing a report, and the shape of it is worth noticing. He gives the jurisdiction, the offence, the method and the motive, and then names the party requesting assistance. It is the way you would brief colleagues, not the way you would rally troops.
The phrase about saving the living and destroying the monster is the whole journey in four characters, and Wukong puts it in his master's mouth. Whatever the novel thinks of Tripitaka's competence, it is consistent that the impulse to intervene starts with him.
