盡力一扯 A Pull From The Hilltop
他卻跳出營外，去那空闊山頭上，落下雲，雙手把繩盡力一扯，老魔心裡才疼。他害疼，往上一掙，大聖復往下一扯。他却跳出营外，去那空阔山头上，落下云，双手把绳尽力一扯，老魔心里才疼。他害疼，往上一挣，大圣复往下一扯。

他卻跳出營外，去那空闊山頭上，落下雲，雙手把繩盡力一扯，老魔心裡才疼。
他却跳出营外，去那空阔山头上，落下云，双手把绳尽力一扯，老魔心里才疼。
He sprang clear of the camp, went to an open hilltop, came down from his cloud, took the cord in both hands and hauled with all his force. Only then did the old fiend's heart begin to hurt.
落 keeps luò, to come down, throughout this edition.
他害疼，往上一掙，大聖復往下一扯。
他害疼，往上一挣，大圣复往下一扯。
The fiend, in his pain, strained upward, and the Great Sage hauled downward again.
掙 reads zhēng — to strain against something, not the zhèng that means to earn.
The geography does all the work here. Wukong needed open ground, and now he has it, but not for the reason the third demon intended. Height and distance are what make the cord useful: from a hilltop he can pull downward, and there is nobody near enough to interfere.
The exchange that follows is pure mechanics — he strains up, Wukong hauls down — and the novel presents it without a word of commentary. It does not need any. Two sentences establish that the demon's own strength is now working against his own heart, and that the harder he resists the worse it gets.
