No more of the master and disciples resting on the road.

不說…且說 is the storyteller changing camera: leave them there, and turn to the abbey. Both halves of the formula appear here and in the next line.

Now that Great Immortal rose at daybreak, ate his morning meal, came out on the hall, and ordered: "Fetch the whip—today it falls to Tang Sanzang to be beaten."

Morning at the abbey, and the routine is horribly ordinary: get up, eat breakfast, come out to the hall, call for the whip. 早齋, zǎo zhāi, is the morning meal in a religious house, meat-free by rule. 卻該打唐三藏了, "today it falls to Tang Sanzang" — a rota. 藏 is zàng.

That little immortal swung the whip and said to the Tang Monk, "I'm going to beat you."

掄著鞭, swinging the whip, takes 著 as zhe, marking the action in progress. 打你哩, "I'm going to beat you now" — announced first, which turns out to be a mistake.

And that willow tree answered too: "Beat away."

And the tree answers. 打麼, "beat away, then" — two syllables, and the funniest line in the chapter. 應 is yìng, "to answer."

Thwack and whack, thirty strokes were laid on.

乒乓, pīng pāng, is the same sound-word the cudgel made against the manfruit tree forty passages back, and it is doing the same job: something wooden is being hit hard.

He swung the whip round and said to Bajie, "I'm going to beat you."

掄過鞭來, swinging the whip round to the next one along.

And that willow tree answered too: "Beat away."

The same two syllables again. Repetition is the whole technique of this passage.

And when he came to beat Wujing, it too answered, telling him to beat on.

And a third time, with the narrator now too bored to quote it in full. 教打 takes 教 as jiào, "let, tell to."
