天宮借刀 Borrowing the Blades in Heaven
惠岸領命，即駕雲頭，徑入南天門裡，到雲樓宮殿，見父王下拜。天王見了，問：「兒從何來？」木叉道：「師父是孫悟空請來降妖，著兒拜上父王，將天罡刀借了一用。」天王即喚哪吒將刀取三十六把，遞與木叉。木叉對哪吒說：「兄弟，你回去多拜上母親：我事緊急，等送刀來再磕頭罷。」忙忙相別，按落祥光，徑至南海，將刀捧與菩薩。惠岸领命，即驾云头，径入南天门里，到云楼宫殿，见父王下拜。天王见了，问：「儿从何来？」木叉道：「师父是孙悟空请来降妖，着儿拜上父王，将天罡刀借了一用。」天王即唤哪咤将刀取三十六把，递与木叉。木叉对哪咤说：「兄弟，你回去多拜上母亲：我事紧急，等送刀来再磕头罢。」忙忙相别，按落祥光，径至南海，将刀捧与菩萨。
逐句解 Line by line
Moksha received the charge, mounted a cloud-head, went straight in through the Southern Gate of Heaven, came to the Cloud-Tower Palace, and, seeing his father the King, bowed down.
Straight up through the 南天門, the Southern Gate of Heaven, to his father's court.
The Heavenly King, seeing him, asked: "Son, whence do you come?"
The Heavenly King greets him as a father, not a commander. 兒 is ér, son.
Muzha said: "My teacher was invited by Sun Wukong to subdue a fiend, and she bade your son bow before you, Father King, and borrow the Sky-Net Blades for a single use."
The request, delivered with full formality. 降 in 降妖 is xiáng, subdue; 著 in 著兒拜上 is zhuó, the sending-someone reading — she bade your son bow before you; 兒 is ér; 將 in 將天罡刀 is jiāng.
The Heavenly King at once called Nezha to take the blades — thirty-six of them — and hand them to Muzha.
And the brother who fetches them is Nezha — 哪 read né, only in this name — the third son, and one of the more famous fighters in Chinese legend. 將 in 將刀取 is jiāng.
Muzha said to Nezha: "Brother, when you go back, make many bows to our mother for me: my errand is urgent, so let me kowtow when I've delivered the blades and returned."
The most human line in the passage: give my regards to mother, I am in a hurry, I will kowtow properly when I bring the blades back. 哪 is né; 罷 in 再磕頭罷 is the soft ba.
In great haste they parted, and, pressing down his auspicious light, he came straight to the Southern Sea and offered the blades up to the Bodhisattva with both hands.
相 in 相別 is xiāng, parted from one another; 落 in 按落 is luò, pressed down; 將 in 將刀捧與 is jiāng.
The errand in Heaven is dispatched in a few brisk strokes: Moksha's ascent to his father's Cloud-Tower Palace, the ready loan of the thirty-six blades through his brother Nezha, and his hurried apology to his mother — let me kowtow properly once the blades are delivered. The celestial family is sketched with an affectionate economy, and the scene's very efficiency is the point. The machinery of the rescue clicks into place without friction, the blades passing from Li Jing's household into the Bodhisattva's hand within a breath. Set against the long comedy of Wukong's stalling and the petal-and-breath marvels, this quick dispatch signals that the rescue is now genuinely underway: the instrument of Red Boy's undoing is in hand, and Guanyin can turn at last toward the Fire-Cloud Cave.
The domestic touch does real work here. A chapter that opened with a counterfeit father kneeling to a false son now shows an actual son at his actual father's court, asking a favor and sending word to his mother — the genuine article set beside the forgery, without comment. Moksha gets his blades in three lines because nothing between him and his family needs negotiating, which is exactly what Wukong spent nine passages failing to counterfeit.
