Apocalypse Transmigration: Save the Female Lead? Are You Insane?

Ye Yiyi: "System, what kind of joke are you playing? You want me, a weak woman without the strength to truss a chicken, to go to an apocalypse swarming with zombies and save that awesome female lead? Are you out of your mind?"

System: "Heh, if it weren't for my landing error, would I even be looking for you?"

Ye Yiyi: "What did you say?"

System: "Nothing, nothing. My dear, drop-dead gorgeous beauty, please help me. Complete the mission, and I'll give you endless wealth."

Ye Yiyi: "Ahem, it's not like I can't. I am a good citizen, after all."

By the time Ye Yiyi actually met the female lead, ahem, she realized she didn't need the wealth; just the "big sister" would be fine.

System: "Hehe, where's your face?"

Yang Luoliu: "Right here. (Draws knife) Got a problem with that?"

System: "Can't afford to provoke, can't afford to provoke, running away, running away. Tsk, what a loss."

Reborn, cold-faced, difficult-to-get-along-with, super invincible strong 'gong' vs. transmigrated, outwardly pure and kind, secretly grumbling 'shou'.

The female lead wasn't reborn from the very beginning. After all, with her reborn personality, she probably would have "offed" her own little darling from the start.

Double purity, 1v1. Please note, it's a dual-female lead story. Don't come in, read half, then say you misunderstood and curse me; I'll... I'll just get angry out of anger.
