手癢認看 Eight Rules Flies Up
正說間,只聽半空中喧嘩亂嚷。慌得都出來看,卻是兩個行者打將來。八戒見了,忍不住手癢道:「等我去認認看。」好獃子,急縱身跳起,望空高叫道:「師兄莫嚷,我老豬來也!」那兩個一齊應道:「兄弟,來打妖精,來打妖精。」正说间,只听半空中喧哗乱嚷。慌得都出来看,却是两个行者打将来。八戒见了,忍不住手痒道:「等我去认认看。」好呆子,急纵身跳起,望空高叫道:「师兄莫嚷,我老猪来也!」那两个一齐应道:「兄弟,来打妖精,来打妖精。」
逐句解 Line by line
Just as they were speaking, they heard a clamour and wild brawling in mid-air.
正說間 jiān, in the midst of speaking. 喧嘩 huá — pypinyin bakes huā; the graph is held invariant at huá corpus-wide.
In alarm they all came out to look, and it was the two Pilgrims come fighting hither.
打將來 — 將 jiāng, the vernacular verbal infix of motion toward the speaker, as at blk3. 慌得 de, the complement.
Eight Rules saw them, and could not contain the itching of his hands: "Let me go and have a try at telling them apart."
手癢 'hands itching', the idiom for an itch to join a fight. 認認看 — the reduplicated verb plus 看 'and see', i.e. give it a try.
Good idiot! He sprang up in haste, leapt aloft, and called out high into the air: "Elder brother, stop your brawling — old Hog is here!"
好獃子 'good idiot' is the narrator's affectionate epithet for Eight Rules, used at the head of a burst of action. 獃子 takes neutral zi.
The two of them answered together: "Brother, come and fight the fiend! Come and fight the fiend!"
應 yìng, to answer — pypinyin bakes yīng. The line is printed twice because two mouths speak it, the same device as at 我和你見師父去.
Eight Rules arrives at the problem last and approaches it with perfect confidence, which is exactly his function in the novel. 等我去認認看 — let me go and have a try at telling them apart — is offered after the Bodhisattva, the celestial host, the Jade Emperor and a demon-revealing mirror have all failed at precisely this task.
The answer he gets is the joke and also the point. He calls up 師兄莫嚷, addressing one elder brother, and two voices reply 兄弟 in unison, both inviting him to come and fight the fiend. Each is asking him to help kill the other. The invitation is identical from both sides, which leaves Eight Rules with exactly the problem Sha Monk had at the Water-Curtain Cave, and no more equipment for solving it.
