山門外叫戰 Calling For Battle At The Gate
行者拜謝了祖師,即同龜、蛇、龍神各帶精銳之兵,復轉西洲之界。不一日,到了小雷音寺,按下雲頭,徑至山門外叫戰。行者拜谢了祖师,即同龟、蛇、龙神各带精锐之兵,复转西洲之界。不一日,到了小雷音寺,按下云头,径至山门外叫战。
逐句解 Line by line
Pilgrim made his thanks to the Patriarch and set off at once with Tortoise, Snake and the dragon gods, each bringing his crack troops, back to the border of the Western Continent.
精銳之兵, crack troops, is the first sign that the loan is bigger than the two generals the god actually named. The dragons have brought soldiers of their own.
Before a day was out they reached the Monastery of Little Thunderclap, pressed down their cloud-heads, and went straight up outside the mountain gate to call for battle.
按下雲頭 repeats, with 下 where the earlier line had 落, the gesture Monkey made arriving at Mount Wudang: 輕輕按落雲頭. The difference is that this time he is not alone.
Two segments carry the whole journey out. The chapter spends a long scene on the asking and four clauses on the getting there, which is the usual proportion in this novel: negotiation is dramatised, travel is summarised.
叫戰 — calling for battle — is the operative phrase. Monkey does not go to the gate to talk, or to look for his master, or to try a rescue by stealth; he tried all of those in the previous chapter. He arrives with borrowed troops and challenges, which is the one approach left.
