Watch him work his magic now — flourishing his passes, he came spinning back through the Crystal Palace.

打轉 — "spun / circled round"; 轉 here reads zhuàn (fourth tone, "to revolve, circle"). 丟開解數 — "flourishing his martial passes," 解數 (jiě-shù). The display intimidates the whole court.

He frightened the old Dragon King out of his wits and scattered the souls of the little dragon-princes; the turtles, soft-shells, great tortoises, and river-lizards all drew in their necks, and the fish, shrimp, sea-turtles, and crabs all hid their heads.

諕得 — "frightened so that…" (諕 = 嚇, xià). 小龍子 — "the little dragon-princes," 子 read zǐ ("son"). 魂飛魄散 — "souls fly and spirits scatter," 散 sàn. 龜鱉黿鼉 (turtle, soft-shell, great tortoise, river-lizard) and 魚蝦鰲蟹 (fish, shrimp, sea-turtle, crab) form a comic zoological parallel. 盡藏頭 — "all hid their heads"; here 藏 reads cáng ("to hide," the verb), distinct from 海藏's zàng ("treasury") earlier in the chapter — the same graph, two readings.

Wukong held the treasure in his hand and sat down in the Crystal Palace hall, saying to the Dragon King with a smile: 'Many thanks, worthy neighbor, for your kindness.' The Dragon King said, 'Don't mention it, don't mention it.'

將 is the object-marking preposition jiāng (= 把): 將寶貝執在手中. 厚意 — "kind regard." 不敢 (twice) — "you flatter me / don't mention it," a self-deprecating courtesy; 不 bù (before third-tone 敢).

Wukong said, 'This piece of iron is fine to use — but there is one more thing.' The Dragon King said, 'What else does the Honored Immortal have to say?'

這塊鐵 — 塊 kuài, the classifier for lumps. 還有一說 — "there is one more point"; 還 hái, 一 taking yì (before first-tone 說). The transition from gift to demand.

Wukong said, 'Had there been no such iron just now, it would have been all right; but now that I have it in hand, I have no clothing to match it on my body. What is to be done?

當時 — "at that time"; 當 reads dāng (first tone). 倒也罷了 — "it would have been all right after all"; 倒 dào (the adverb, as in 倒好), 罷了 the dismissive particle (罷 bà, 了 le). 拿著他 — 著 the durative zhe. 相趁 — "to match, suit"; 趁 chèn. He now demands armor to "match" the rod.

If you have any armor here, just give me a suit, and I'll thank you for the whole lot.' The Dragon King said, 'That I really do not have.'

披掛 — "armor, full accoutrements" (pī-guà). 索性 — "simply, outright" (suǒ-xìng). 一副 takes yí (before fourth-tone 副); 一總 takes yì (before third-tone 總). 卻是沒有 — "really do not have."

Wukong said, 'One guest does not trouble two hosts. If you have none, I simply will not leave by this gate.'

一客不犯二主 — a proverb, "one guest does not impose on two hosts" (i.e. I'll get everything from you alone); 一 yí (before fourth-tone 客), 不 bú (before fourth-tone 犯). 定不出此門 — "will definitely not leave by this gate"; here 不 bù (before first-tone 出) — a flat threat beneath the courtesy.

The Dragon King said, 'May I trouble the Honored Immortal to go round to another sea — perhaps there is some there.' Wukong said again, 'Going to three houses is not as good as sitting at one. I beg you, by all means, for a suit.'

煩 — "may I trouble you to…" 再轉一海 — "go round to one more sea"; 轉 zhuǎn, 一 yì (before third-tone 海). 走三家不如坐一家 — a proverb, "going to three houses is worse than sitting at one"; 不如 takes bù (before second-tone 如), and 坐一家's 一 takes yì (before first-tone 家). 告求一副 — 一 yí (before 副).

The Dragon King said, 'Truly I have none; if I had, I would present it at once.' Wukong said, 'Truly none? Then I'll just try this iron out on you!'

委的 — "truly" (cf. earlier). 即當奉承 — "would at once present it"; 當 dāng (first tone, "shall, ought"), and 奉承 here means "to offer up, present" (not "flatter"). 就和你試試此鐵 — "then I'll try this iron out on you"; 和 reads hé (the preposition "with, on"). The threat sharpens.

Panicking, the Dragon King said, 'Honored Immortal, do not raise your hand, do not raise your hand! Let me see whether my brothers have any; I'll have a suit sent.'

切莫動手 — "by all means do not raise your hand"; 切 qiè ("be sure to"). 舍弟 — "my younger brothers," 舍 read shè (the humble "my," not shě "to give up"). 處 chù. 當送一副 — 當 dāng, 一 yí.

Wukong said, 'Where are these brothers of yours?' The Dragon King said, 'My younger brothers are Ao Qin, Dragon King of the Southern Sea; Ao Shun, Dragon King of the Northern Sea; and Ao Run, Dragon King of the Western Sea.'

令弟 — "your (honorable) younger brothers," 令 lìng the polite "your" (paired against the humble 舍 of 舍弟). The three brothers — 敖欽 (Ao Qin, South), 敖順 (Ao Shun, North), 敖閏 (Ao Run, West) — complete the four Dragon Kings of the seas; 閏 rùn.

Wukong said, 'Old Sun will not go, will not go. As the saying goes, "three on credit are no match for two in hand." I only ask that you make do, high or low, and send me a suit, and there's an end of it.'

不去 (twice) takes bú (before fourth-tone 去). 俗語謂 — "as the proverb says": 賒三不敵見二, "three [things] on credit are no match for two seen [in hand]"; 賒 shē ("to buy on credit"), 不敵 taking bù (before second-tone 敵), and 見 here jiàn ("seen, in sight"). 隨高就低 — "make do, high or low; take whatever there is." 一副 takes yí; 便了 closes the speech.

The old Dragon said, 'There is no need for the Honored Immortal to go. I have here an iron drum and a golden bell; whenever there is an urgent matter, we beat the drum till it sounds and strike the bell till it rings, and my brothers arrive in an instant.'

不須 — "there is no need"; 不 bù (before first-tone 須). 一面鐵鼓 — 一 yí (before fourth-tone 面); 一口金鐘 — 一 yì (before third-tone 口). 擂得鼓響 / 撞得鐘鳴 — "beat the drum till it sounds / strike the bell till it rings"; 擂 léi ("to beat a drum"), with 得 the resultative de in both. 頃刻而至 — "arrive in an instant."

Wukong said, 'If that's so, go quickly and beat the drum and strike the bell.' Sure enough, the River-Lizard General went to strike the bell, and the Soft-shell Marshal came to beat the drum.

既是如此 — "since it is so." 快些 — "quickly." 鼉將 / 鱉帥 — "the River-Lizard General" and "the Soft-shell Marshal," 將 jiàng and 帥 shuài, two more comic ranks of the dragon-court (cf. the fish-officials of 其六).
