Pilgrim said, "A demon who picks people up with his nose is easy enough to take."
也好拿 is easy enough to catch — a dismissal offered aloud, in the officer's voice, about a creature he has just been told is unstoppable.
He spoke up again. "And how much can the third king do?"
幾多手段 is how much capability — the same word for a person's range that has run through the whole interrogation. Third time of asking, third yìng.
The Little Borer of the Wind said, "Our third king is no creature of the mortal world. He is styled the Roc of Ten Thousand Li of Cloud-Road.
凡間之怪物 is a monster of the ordinary world, and the third king is explicitly not one. 雲程萬里鵬 names him: the 鵬 is the vast bird of the 莊子, which in the opening of that book turns from a fish and flies ninety thousand lǐ. The name is a literary citation, and everybody hearing it would have caught the reference.
Pilgrim's dismissal of the second king is spoken aloud and is pure performance. He has just been told that armour is useless and answers that it sounds manageable.
Then the third king arrives and the register changes completely. Not a monster of this world, and named rather than described — which in this novel is always the signal that something serious has entered.
The name is a quotation. The Roc opens the 莊子, transformed from a fish, beating up ninety thousand lǐ to head south, and it is the standard Chinese image for scale beyond comprehension. A demon called after it is being placed in a different category from the other two.
