[No Male Lead + Strong Female Lead + Behind-the-Scenes Style + Fantasy] Also known as [Shocking! I'm Just an Ordinary Girl]

When all the antagonist's plans fell through, he was walking down the street when a girl passed by. He had a strange premonition, reached out to stop her, and asked, “Hello, do we know each other?”

The red-haired girl carrying a violin turned around, took the lollipop from her mouth, and smiled. “Nice to meet you. My name is Lin Xi, but we can get to know each other.”

Lin Xi accidentally transmigrated into a novel called Absolute Ban, becoming an insignificant background character. This world is facing an invasion by monstrous beasts, while an Evil God pulls the strings behind the scenes, plunging humanity into an unprecedented crisis. As the protagonist team’s secret guardian, Lin Xi must quietly help them grow and fight powerful enemies without revealing her identity.

Using her wits and the abilities granted by her System, she secretly foils the enemy’s schemes, creates powerful items, and provides crucial intelligence. However, as an unknown force invades, Lin Xi’s actions gradually attract the antagonist’s attention. She must protect the protagonist team while concealing her identity and avoiding discovery by the forces of evil.

In this war for the survival of the world, how will Lin Xi secretly protect it while remaining an insignificant background character? Can her existence change the final outcome?
