逐句解 Line by line
Pilgrim ran up to them, whipped out his rod and shouted, "I'll teach you, you pack of hairballs!
毛團, hair-ball, is a genuinely good insult and it is aimed with precision: both of them are furry animals under the disguise, and he has worked that out before either has changed shape. It is also, from a monkey, a magnificently unselfaware thing to say.
What 'fine chance'?
Five characters, quoting their own words back at them. Wukong has been standing behind the screen long enough to have heard the whole conversation, and he opens with the one phrase that proves it.
Take my rod!"
The catchphrase, unchanged since the beginning of the book.
The old fiend dropped the beauty, swung up his coiled-dragon staff and hurried to meet him.
丟了美人 — he drops her. Given how the chapter ends, that half-second of self-preservation is worth remembering: the attachment is real but it is not the first thing he reaches for.
The confrontation is over in four short units and three of them are Wukong talking. He does not announce himself, explain, or accuse; he insults them, quotes them, and swings.
There is a nice piece of construction in the ordering. He has just overheard the two of them mourn a three-year plan; the audience has therefore heard the villains admit everything, in private, with no one to perform for. Nothing after this requires proof.
