Modern associate academician Xia Mengqi unexpectedly transmigrates to France in 1868, near the end of the Second Empire, and becomes Charlotte Bonaparte, a member of the Bonaparte family. Using her modern knowledge, she secretly advances steam engine improvements, standardized production, and reforms to the military training system, gradually winning support from her family and the military. Faced with Prussia's rise and obstruction from conservative forces at home, she decisively launches the "Tuileries Palace Coup," purges corruption with an iron hand, enacts civil rights legislation, and establishes an efficient industrial system. With the Prussian army closing in, she delivers the "May Day Declaration" at the Champ de Mars in Paris. Its central message, "Freedom is not a gift from monarchs; it is won by the people's own hands," ignites the people's fighting spirit and unites the empire against its old enemy.
