Shen Zhaoning, a social beast, was stolen by his boss Xiao Yan and accidentally traveled through time to become a waste queen who was about to drink poison. When she was about to die, she activated the dynasty dimensionality reduction system and unlocked the Maginot Line at the beginning to save her life. The enemy commander outside the city turned out to be Xiao, a fellow time traveler. The opponent had a civilization accelerator system and repeatedly used biochemically modified soldiers and electromagnetic weapons to plot against her. Shen Zhaoning relied on intelligence hacking, tank production lines, genetic enhancement and other technologies to fight back step by step, conquered the loyal general Huo Chuan, purged the court of collaborators and traitors, defeated Xiao Yan's 300,000-strong army, and personally ended the dual enemies of the past and present. Later, she exposed the conspiracy of the ignorant king to betray the country and flee, and took over the world instead. She comprehensively implemented industrial reforms, laid railways, and developed steam engines. When the local civilization was rising, she noticed the changes in the alien civilization in the west, and officially launched the interstellar colonization plan, using the power of dimensionality reduction to go to the wider star world.
