這等慌張 Why So Flustered As This
那八戒依言，分開水路。行者變作怪像前走，八戒吆吆喝喝後追。漸漸追至龍宮，只見那萬聖公主道：「駙馬，怎麼這等慌張？」行者道：「那八戒得勝，把我趕將進來，覺道不能敵他。你快把寶貝好生藏了。」那八戒依言，分开水路。行者变作怪像前走，八戒吆吆喝喝后追。渐渐追至龙宫，只见那万圣公主道：「驸马，怎么这等慌张？」行者道：「那八戒得胜，把我赶将进来，觉道不能敌他。你快把宝贝好生藏了。」
逐句解 Line by line
Eight Rules did as he was told and parted the water.
分 is fēn, to divide, and 那 is deictic. Nine graphs, a short narrator's clause, standing alone on grammar rather than measure — the sixth of its kind in the chapter. 依言 is to act on what was said, and it is all the assent the plan gets.
Pilgrim changed into the fiend's shape and went in front; Eight Rules came bawling and shouting behind.
Both 喝 are hè, the shouting band, and both specs are given by position; pypinyin supplies hē, to drink, at each. 吆吆喝喝 doubles a reduplicated binome to make the pursuit as noisy as possible, which is the whole point of it — the noise is the performance.
By degrees the chase came to the dragon palace, and there was the Myriad Sage princess, saying, "Husband, why so flustered as this?"
那 is deictic. 只見 is the chapter's single occurrence of that tag and it introduces no verse; it does the ordinary work of turning the reader's attention to what is in front of the characters. The princess has been named nine times in this chapter and in the one before it, and this is the only place in either where she is given a line to say.
Pilgrim said, "That Eight Rules has the better of it. He has driven me in here, and I feel I am no match for him.
得勝 takes 得 at dé, the full verb. 趕將進來 takes 將 as the vernacular verbal infix, jiāng. 覺 is jué, to feel or be aware, and its dipping value keeps 不 at bù in the clause that follows.
Get the treasures well hidden, and be quick about it."
藏 is cáng, to hide — not the zàng of the scripture-baskets that this same stretch will take three times over at 三藏. A quote-closing tail at nine graphs, past the under-eight threshold, so it stands alone.
The trick is a piece of theatre and both players know their parts. Pilgrim wears the son-in-law's face and runs; Eight Rules chases him, making as much noise as he can. The text says so in the verb it chooses — 吆吆喝喝, bawling and shouting — because a silent pursuit would convince nobody.
What sells it is that Pilgrim volunteers a defeat. He does not ask for the treasure; he reports that he is losing, and lets the princess draw the conclusion. The instruction he gives is one any householder would give: put the valuables somewhere safe.
The princess has been named in depositions since the previous chapter and led away to hide once, but this is the first time she speaks in her own voice. What she says is a wife's question about her husband's face.
