I Mistook the Hidden Boss for Someone Else, and the Story Went Off the Rails

(Real life has been so busy. I work during the day, and my child is in elementary school now, so I have to help with homework at night. It's exhausting, I'm crying. Once things calm down and I have time, I'll keep writing! Thanks for understanding, everyone.)

Qi Yue transmigrates into a cultivation novel as a disposable senior sister. To help the heroine ascend to immortality and eventually live happily ever after with the male lead, she exhausts her spiritual power and works herself to death!

Qi Yue: I'm a naturally gifted person who could become immortal just by lying flat. Work myself to death?

Whoever wants to be that unlucky disposable character can have the job. She has to stay hard-hearted!

But as she spends her days trying to keep her heart hardened...

The heroine gets tricked by a scumbag into stealing a spirit pill and is injured in a fall.

The heroine gets tricked by a wicked demon into drinking poison, and bleeds from every orifice.

Qi Yue's intolerance for stupidity kicks in, and she can't stay hard-hearted at all.

So she drags out the male lead, who's been missing for fifty chapters, and forces him to take responsibility for the heroine.

The male lead in the original book: gentle, considerate, and every inch a gentleman.

The male lead Qi Yue finds: "Keep yapping and I'll kill you!"

Qi Yue: ??

This guy... he's not the right one!

Nan Xuan has barely been reborn when someone knocks him out and ties him up.

Nan Xuan at first: I've never met such an arrogant, overbearing villainess!

Nan Xuan later: I've never met such a... brave and resourceful woman.

Theme: When facing injustice, stay hard-hearted to the very end.
