掙挫不得 No Struggling Left Or Right

逐句解 Line by line
This monster went ninety thousand li at a single beat of his wings, and with two beats he had overtaken him.
Do the arithmetic the text is inviting: two beats is 180,000 lǐ against the somersault's 108,000. The roc is not a little faster. He is roughly two-thirds as fast again over the same span, and the book wants you to be able to check it.
So he was caught in one grip and held in the fiend's hand, unable to wrench himself free to left or right.
撾, to grip or claw, is a character most dictionaries mishandle; it reads zhuā. Note 一把, one grab — the whole capture takes a single movement of one hand.
He thought of running, but there was no getting away.
Eight characters, two clauses, and the second cancels the first. The narrator is closing exits one at a time.
Even his arts of transformation and escape were of no use coming or going: when he made himself bigger, the fiend loosened his grip;
變化法遁法 names the two escape kits Wukong has relied on since the opening chapters — changing shape, and the arts of vanishing. Both are listed here so that both can be crossed off.
The chase is settled by numbers, and the numbers are given so the reader can settle it themselves. This is unusual. Most fantasy asks you to accept that the new threat is worse; this one hands you two distances and lets you divide.
Then comes the genuinely clever part. Wukong's escape from any grip has always been to change size, and the roc's counter is simply to change grip with him. Bigger, and the hand opens to fit. Smaller, and the hand closes to match. The trick is not defeated by force but by a captor who is paying attention.
That is what makes this defeat different from the beatings Wukong has taken before. He is not outfought. He is out-thought by an opponent who has watched him work and knows what he is going to try.
