A Chemistry PhD Transmigrates to the Republican Era: The Marshal Goes on a Killing Spree

Chemistry PhD Su Qingyuan transmigrates after a lab explosion into the body of A Yuan, a wretched performer in a Republic-era variety troupe. A cruel troupe leader forces her to swallow swords, while marauding soldiers burn, kill, and loot. At the brink of death, she uses plant ash to stop bleeding with one hand and saltpeter to create smoke with the other, carving out a slim chance of survival in this living hell. Her unusual behavior catches the eye of Lu Zhengnian, the most powerful warlord in the north. This ruthless, bloodthirsty man is rumored to have no interest in women, yet he keeps her close under his protection. He shelters her because he recognizes the astonishing knowledge in her mind: how to make explosives, treat wounds and illnesses, and enrich the nation and strengthen its military. Before long, she becomes the most extraordinary person at the Marshal’s side. When others mock her lowly origins, she turns around and refines coal tar into medicine, saving an entire camp of wounded soldiers. When enemy troops sneer at her for being a woman, the improved shells she designs shake their camp to its foundations. A fake heiress slanders her, so she exposes her true colors by testing for poison in front of everyone. A foreign envoy looks down on her, so she uses chemical formulas at the negotiating table to reclaim the nation’s resource rights. Lu Zhengnian realizes that the person he took in is no pitiful canary, but an eagle capable of soaring and fighting alongside him. He sweeps away her enemies, and she helps him end the warlord era. In this war-torn age, chemistry is her sharpest sword, while the Marshal who holds power over all becomes her only weakness and her armor.
