Everyone Knows the Truth: I'm the Only One Kept in the Dark

I transmigrated to another world, where demons and monsters run rampant. I'm panicking.

Luckily, I awakened a Quest System, and completing quests makes me stronger.

I was born into the most powerful Ye family.

Here, I have parents who dote on me,

and kind, friendly siblings.

I joined the strongest sect,

where the sect leader is my master,

and I even have a senior brother who swore to protect me to the death.

But then,

one day,

someone unlocked my sealed memories,

and I discovered

that my family was fake,

the sect was fake,

even the lucky encounters I had on my outings were fake,

and most absurdly, my lover was fake too.

What should I do? I'm freaking out. Fellow readers, please give me some advice. It's urgent.
