When four-and-a-half-year-old Su Nuannuan rises on tiptoe and pours the “sweet water” from her baby bottle over a rusty Western Han bronze cauldron in a museum, the whole world is stunned. Her livestream instantly goes wild, with people across the internet denouncing her as a “brat who destroyed a national treasure”! But what happens next leaves everyone speechless: the thousand-year-old rust flakes away, revealing long-lost inscriptions on the cauldron's dark golden surface!
This isn't an accident. It's the beginning of a mission. A mysterious System called the “Guardian of the National Spirit” is bound to Nuannuan. Her baby bottle holds a restorative elixir granted by the System, and her eyes can see the “national spirit” sleeping deep within cultural relics. Overnight, this ordinary little girl becomes someone the Palace Museum director, Qin Yu'an, visits in person late at night to beg to take on as his apprentice. She also becomes the focus of the loving yet weighty duty of protection borne by her young parents, Su Ming and Lin Wan.
But the awakening of her abilities also draws out a shadow. The ancient, evil organization “Shadows of Oblivion” emerges from the depths of history. Their mission is to destroy cultural relics and erase history, and they are determined to stop Nuannuan. As she faces a tidal wave of online criticism, scrutiny from the authorities, and one destructive scheme after another from the Shadows of Oblivion, Nuannuan is no longer fighting alone. The passionate bodyguard Chen Mo, Guochao musician A Jie, genius hacker Xiao Hui, and a diverse group of companions gather around her to form the unique “National Trend Guardians.”
