My 70s Lunchbox Is a Super Lab

Gu Nian, a top-tier scientific overlord, wakes up in the 1970s, trapped in the body of a 'brainless' educated youth. She's penniless, scorned, and destined to be humiliated by a scheming fiancé and his 'best friend.' The future looks bleak, and her stomach is rumbling with the unfamiliar pangs of hunger. But Gu Nian isn't a pushover. Her ultimate cheat is a secret: a personal canteen from her past life, brimming with delicious food and packed with Nobel-winning research data. This isn't just food; it's a portable lab, a wellspring of forgotten knowledge. With every bite, she regains her strength; with every scroll, she plots her rise. From public face-slapping to building a hidden scientific empire, she’ll make them regret crossing her. But as her silent revolution begins, can she hide her world-shaking abilities from the watchful eyes of the state and a certain intrigued military man?
