The Criminal's Daughter Joins the Army and Unifies the World (Infrastructure)

[Complete] [New story: Popularizing the Rule of Law for Emperor Qin Shi Huang from the Start, updating now~] Starting as the daughter of a convicted minister, ending with the unification of the realm. The Industrial Revolution will help me soar~ Build the nation through infrastructure, unstoppable! Yao Qin transmigrated to an ancient family of military officers. As the older sister of a pair of twins, she lived happily with the Yao family for six years. Then one day, the family was surrounded and their home confiscated. The men were sent to the army, while the women and children were taken into the government entertainment quarters. Her twin brother was just old enough to be sent to the army. But he'd been undersized since birth, and it was questionable whether he could even survive the journey to the army. Yao Qin, on the other hand, had inherited her military-officer grandfather's great strength. She could easily wield a heavy saber and beat up cousins four or five years older than her. In this dynasty, being thin was considered beautiful. Yao Qin worried she'd starve to death after being sent to the government entertainment quarters... As the soldiers came to seize them, Yao Qin stomped her foot, stripped off her brother's clothes, and traded outfits with him. I'll go to the army in my brother's place, earn merit, and leave the army My brother will take my place in the government entertainment quarters, build up his strength, and support me If I earn merit quickly, no one will discover that I'm impersonating a man Perfect! The story of a female marshal's rise, a coming-of-age progression story, from the daughter of a convicted minister to the ruler of a unified realm. The focus is on her career. P.S. The heroine won't become empress or marry the emperor. She founds a country without an emperor and becomes its head of state. There's little romance in the main story~ Bonus scene: Before she'd earned enough military merit to redeem her brother, Yao Qin realized that he was already famous in the capital. Yao Qin: Wait! My brother got too successful. I've only just become a centurion, and he's already famous in the capital, the man of every man's dreams! So men really do understand men better? Can I still get him out?! Special note: !!! All named male characters in the story are straight! There are no BL romantic storylines! The younger brother has no intimate scenes with men! This is BG! The younger brother may not have a romantic pairing before the main story ends. This is a fictional setting, a fictional setting, a fictional setting, with elements from many dynasties blended together. There are countless original details! Please stop asking why the soldiers sent to the army in the story don't get branded, can earn military merit and become officers again, or why the government entertainment quarters only provide singing and dancing instead of matching historical reality! Without these original details, I couldn't write the story. They would have been found out immediately otherwise!!! Theme: Family members helping one another~
