Transmigrated into an Immortal Hero Drama Full of Bugs as the Female Side Character

[Xianxia + Bickering Partners + Friendship + Saving the Second Female Lead + Light Ensemble Cast + Easygoing Humor + Daily Life + Episodic Dungeons]

[A transmigrated junior sister who loves making dumb jokes × the righteous, endlessly unlucky second son of her sect]

After being hit and killed by a semi truck, Su Luying is bound to a System and can't believe her bad luck. Everyone else gets to be a Host, while she's stuck as a temp worker. And she hasn't transmigrated into a book, but into a small world that hasn't even taken shape yet.

The good news: there's only one mission. The bad news: it's SSS-rank.

Su Luying has to play the villainess, taking two rookie sub-Systems with her to find bugs in the small world by following the labels and outline provided by the System and the Heavenly Dao.

The labels promise a happy ending, but the Heavenly Dao's outline demands that the heroine sacrifice herself to merge with the Dao!

The heroine is described as breathtakingly beautiful, but her character model is utterly plain. Fine, I'll use a cursed item to turn her into a female Diarmuid! I'll rewrite the outline too. How about adding a fake-versus-real heiress plot to make her more heroine-like?

The male lead is clearly a Demon Venerable, yet for no reason he personally infiltrates the righteous sect. Fine, I'll rewrite the plot and make you lose your memory and seek the Dao among the righteous. Is that logical enough?

The second male lead's actor was forced into the role by the investors, so he's got a built-in beauty filter and does nothing but stare wide-eyed. Fine, I'll rewrite the plot and make you a poker-faced snake demi-human. Snakes have no expressions or eyelids!

Su Luying gives everything she has, even her parents, to the heroine, but still can't make up for the fact that the heroine truly cares for her and is forced into a relationship with the Demon Venerable because Su Luying follows the plot. So she decides to give up her own life and merge with the Dao in the heroine's place.

The only one whose fate she hasn't changed is the utterly ordinary-looking third male lead. “How about we kill the Demon Venerable and merge with the Dao instead?”
