八戒道：「怕他怎的？
八戒道：「怕他怎的？
Bajie said: "What is there to fear in him?
怎的 — a spoken form of what or how, common in this novel's dialogue.
等我去打他一仗來。」
等我去打他一仗来。」
Let me go and give him a battle."
一仗 counts one engagement — a single bout of fighting, not a campaign.
行者道：「要去便去罷。」
行者道：「要去便去罢。」
Wukong said: "Go then, if you are going."
罷 keeps bà at the end of the sentence.
八戒笑道：「哥啊，去便去，你把那繩兒借與我使使。」
八戒笑道：「哥啊，去便去，你把那绳儿借与我使使。」
Bajie laughed and said: "Brother, I will go — but lend me that cord of yours to use."
使使 doubles the verb to soften the request: just to use a little.
Bajie's courage lasts exactly two lines. He asks what there is to fear, volunteers for the fight, and then, laughing, asks to borrow the rope. The laugh is the tell: he knows what he is doing, and he is trying to get the safety equipment issued without admitting he needs it.
Wukong's reply is five characters of pure indifference — go then, if you are going. He has spent the scene talking Bajie into this and now offers no encouragement whatever. That flatness is how the novel signals that a trap is being laid, and the person laying it is not the demon.
