Building Infrastructure in the Han Dynasty

New novel, Police Officer, but with the Crime Master System. Please add it to your wish list! Here's the blurb: Jiang Xia closed her eyes, opened them, and found herself in the 1980s. She'd become a police officer at a local station, newly assigned after graduating from a secondary police academy, and she had a Crime Master System bound to her. As long as she kept committing crimes and making a name for herself, the System would reward her with all kinds of criminal skills. Looking at the master-level pickpocketing skill the System had awarded her, Jiang Xia's mind collapsed. What was she supposed to do with that? Compete with pickpockets to see who could steal better? She'd thought the System was useless, but it turned out to be incredibly handy for staking out pickpockets. The moment a suspect got the goods, Jiang Xia pinned them down. Her hands moved faster than her brain, and she frisked the suspect from head to toe. She returned the newly stolen money to its owner's pocket, uncovered all the hidden stolen cash her colleagues had missed, and even fished out the pickpocket's razor blade. Her mentor watched her smooth, effortless movements and fell into deep thought. “Xia, don't you think there's something a little off about your technique?” Jiang Xia: ... It's all the fault of this damned System! Later, Jiang Xia gradually unlocked more skills. Crime scene fabrication let her spot a fake scene at a glance and reconstruct what had really happened. Counter-surveillance techniques let her predict the routes murderers would take to escape. Expertise in killing let her identify suspects and the weapons they'd used from the wounds they left behind. She fought crime with crime, using criminals' own skills to solve the toughest cases. But the more cases she solved, the stranger her colleagues and superiors looked at her. How does Jiang Xia understand crime better than all the criminals we've ever caught?! Blurb: After an accident, Han Ying, an intern doctor from the twenty-first century, transmigrates into the body of an ordinary little girl named Ying, living under Emperor Wu of Han. Looking at the new body's little arms and hands, then at her surroundings, which were even worse than a war-ravaged scene in Syria, Han Ying suppresses the urge to curse and gives the heavens the middle finger. The wheels of history keep turning. The decree of favoring all sons in a feudal lord's family casts a covetous eye on the vassal princes, the emperor points his blade at the Xiongnu, and the bugles of war have already sounded. Countless ministers and generals take the stage in this turbulent era... and none of it has anything to do with Han Ying. Looking at her impoverished family, too poor to even eat their fill of beans, Han Ying uses her left hand to pretend to work miracles and her right hand to practice medicine and farm, trying to lead her family to a better life. But the cruel reality deals her an even heavier blow. Want to practice medicine? No medicine! Want to farm? No land! No matter. Having fully realized that medicine can't save the Han, Han Ying turns around and sprints down the path to becoming an official... Theme: When calculating profit, calculate the world's profit; when seeking fame, seek a name that lasts for generations.
