Three Kingdoms: My Identity as the Cao Family's Eldest Son Was Exposed by My Younger Sister

Reborn in the Three Kingdoms era, Cao Ang becomes the eldest son of the Cao family.

But in this life, Cao Ang has no desire to distinguish himself through military service or unite the realm.

So he leaves home, takes the name Lu Ang, and lives an unremarkable life for ten years, spending his days inventing things at home, writing books, and drinking and chatting with friends.

Then one day, his younger sister Lu Lin accidentally wanders into his study and shatters his peaceful life.

Only after Lu Lin discovers all these secrets does she realize, to her astonishment, that her brother is the true big shot of this chaotic age!

Huh? How did I become a princess?...
