現了原身
He Opens His Mouth Wide
老魔見他趕的相近，在坡前立定，迎著風頭，幌一幌現了原身，張開大口，就要來吞八戒。八戒害怕，急抽身往草裡一鑽，也管不得荊針棘刺，也顧不得刮破頭疼，戰兢兢的在草裡聽著梆聲。老魔见他赶的相近，在坡前立定，迎着风头，幌一幌现了原身，张开大口，就要来吞八戒。八戒害怕，急抽身往草里一钻，也管不得荆针棘刺，也顾不得刮破头疼，战兢兢的在草里听着梆声。

Seeing him closing, the old fiend planted himself at the front of the slope, faced into the wind, gave himself a shake and showed his true form, opened his great mouth wide, and made to swallow Bajie.
相 is xiāng, mutually — the gap between them closing. 迎著 takes the light zhe. And 現了原身 is the moment the fight stops being a duel: he has been fighting in a man's shape with a sabre, and this is the lion.
八戒害怕，急抽身往草裡一鑽，也管不得荊針棘刺，也顧不得刮破頭疼，戰兢兢的在草裡聽著梆聲。

Bajie took fright and dived into the grass, caring nothing for the thorns and brambles, minding nothing for the scraped and aching head, and lay there trembling, listening for the sound of the clapper.
鑽 is zuān, the verb — to bore in — and it is the fifteenth of nineteen in this chapter. Both 不得 take the light de. 聽著 takes zhe, and the detail is exact: he cannot see anything from under the grass, so he listens.
總評 Commentary
The retreat was a trap and Bajie is the one who works it out, in the only way available to him — by being frightened enough to hide. The book gives him no credit for it and no blame either; he simply dives, and the thorns are described in more detail than his cowardice.
聽著梆聲 is the small heartbreaking touch. The clapper is the scout's rattle, the one Wukong took off the body in the previous chapter and unslung at the demons' hall. Lying blind in the undergrowth, Bajie is listening for the sound of demons on patrol.
