Before traveling back in time, Su Wan was the "love brain" in the quick travel bureau who only revolved around love scripts, until the patriotic system threw her into the New York Medical College in 1932: "Can't you learn to prevent epidemics? You're stuck in this troubled world watching the spread of the epidemic."
She gritted her teeth and devoured the entire "Bacteriology". When she was making vaccines using local methods in the anti-Japanese base area, she finally dug out "love, love, love" from her heart - it turned out that it was more satisfying to save people than to worry about who loved whom.
There is no lingering love, only a down-to-earth rush. See how Qingping leads the lost souls, breaks the shackles of the plot, integrates her personal light into the galaxy of her home country, and lives her own protagonist in the wave of the times!
