Female hero + soul wear + infrastructure + no fixed male protagonist
On the first day when I traveled through time and became the new emperor of the Nu Zunguo, I was pinned down on the dragon bed by the most beautiful snake assassin in the country.
His silver hair was entangled with my black hair, and his green eyes were filled with poison: "Pay for your sister's life."
I activated the useless counterattack system and locked his ankle with an iron chain with my backhand.
His scales scratched his collarbone as he sneered: "The orcs would rather die than surrender."
Later, I used cement to build the Great Border Wall and used rice seeds to feed hungry tribes.
The tiger tribe's generals knelt down to offer their military talismans, the fox tribe's richest man emptied his treasury, and even the enemy's eagle emperor barged into the royal study with a letter from his family in his mouth.
