A Killer Travels Back to Ancient Times and Leads the Nation to Prosperity

[No romance + strong female lead + business + System + fiercely protective + taking down scumbags]

She had been Blue Star’s number-one assassin, a master of martial arts and a peerless expert in medicine and poison! But after she died, she found herself in an ancient world where people ate nothing but boiled vegetables. The fish smelled foul, and the vegetables tasted bitter... Was this supposed to be the death of her? Luckily, the golden light of over ten billion merits caught the attention of a System equipped with a shop.

Snacks, milk tea, fruit shops: all set! Delicious food: all set!! She also trained countless top experts, planted high-yield crops, made farm tools, raised pigs, forged weapons, and manufactured gunpowder!

Before she knew it, she had turned a poor county into a thriving place, and somehow even became a princess who protected the nation...

Someone tried to assassinate her for ruining their business? She wiped them out! They tried again? She led her people on a night raid into Jiangnan.

She said, “Who cares who did it? Let’s beat up all the old men in Jiangnan first.” The Retired Emperor replied, “Ningchu is right. They deserve a beating!”

She happened to discover that scions of the great clans were trafficking children. She said, “My hands are itching!”

The Retired Emperor said, “Ningchu, I know this business. I’ll bring a sack to put over their heads!”

The great clans paid through the nose to get rid of the troublemaker. The princess who protected the nation said, “I’ll be back next time.”

One day, the emperor was writing a letter home in a panic. “Ningchu, a million enemy troops are at our borders...”

“Urgent report! Victory dispatch, delivered at full speed! The princess has taken the Retired Emperor and stormed the enemy’s lair!”

The emperor: ???

She can kill ten men in five steps and vanish a thousand miles without a trace!

You all think Huaguo is weak? Sorry, I’m going to unite the world! Submit or die?

(A heads-up: The first forty or so chapters are cozy and slow-paced. From chapter fifty onward, the heroine goes full power-fantasy, and she’s a beast in a fight!)
