After her grandfather's death, Bai Hanyun was disowned by her parents and cast out of the Bai family. With nowhere else to go, she left the city and returned to the countryside. There, by a twist of fate, she discovered an antique mirror hidden in the basement of her newly purchased home. From that moment on, strange events began to unfold—until one day, she stumbled upon a prayer from a young general.

Feng Xiyan, besieged by the Yuezhi Tribe and betrayed by the imperial court, had been driven into a desperate corner. With no access to water, food, or medicine, he and the citizens of Xiqiang City could do nothing but await death. But just as all hope seemed lost, Heaven intervened. From that moment on, the Feng Army and the people of Xiqiang City had enough food and water, living lives more prosperous than even the Emperor himself.

After typing for a moment, Bai Hanyun pressed send and waited.


[Boss Li, I want to buy more glutinous rice and quicklime. Do you still have stock?]


Bai Hanyun didn't have to wait long before Li Dagou replied: [Yes. Miss Bai, how much do you want?]


Reading the message, Bai Hanyun rubbed her chin and thought, 'I remember that for 5 kilograms of glutinous rice slurry, it takes 60 kilograms of quicklime powder to get a standard mixture consistency.'


With that in mind, she opened the AI app and used it to calculate how much glutinous rice and quicklime would be needed to cover a 500-meter-long city wall.


A few seconds later, she got the result.


Looking at the calculation, she muttered, "So I need 1,875 tons of glutinous rice and 22,500 tons of quicklime to cover a 500-meter-long city wall with a thickness of 50 centimeters. I wonder if Boss Li has enough stock."
