Level Zero Conquest Manual

Alice had lived through her ninth winter since she was old enough to understand the world. Overnight, her brown hair turned silver-white, the distinctive trait of the prestigious House of Duke Roigus. Three days later, she went from an ordinary village girl to the young lady of a ducal house in the blink of an eye. The only thing that accompanied her into the duke's household was a completely useless, black leather-bound book.

The spirit dwelling inside the book told her, "You are the heroine of this story. My duty is to help you win over every capture target, rise to the top, and become a winner in life!"

However, the strategy book was completely blank. It was a "Level Zero Strategy Manual" whose functions had to be unlocked by leveling up.

The prince, the duke's son, the chancellor's son, the knight captain's son, the young master of a great merchant house...

Facing the duke's adopted daughter, who held a fully upgraded manual, she seemed to have fallen behind from the very start. The capture targets the spirit had mentioned had already been won over.

In that case, she could focus on making money and aim to spend her future days lounging at home and counting her riches.

That is, until she met the twin sons of a marquis from the borderlands. Alice heard a voice from the strategy manual.

[Main Quest Updated: Win over the genius twins of the House of Marquis O'Connor and prevent them from turning evil and destroying the world]

Black hair and blue eyes: Salt, the free-spirited twin brother and a magic prodigy with talent in every element

Black hair and red eyes: East, the cheerful and upright twin brother, a master of all eighteen martial arts

They both seem like perfect winners in life.

Wait, what do you mean, destroy the world?!

Notes:

1. A true heiress's happy-ending battle chronicle, with the System's cheat gradually unlocking

2. Choose one of the twin brothers as the male lead, or choose neither
