Shen Zhiyi traveled through time.
Dressed as the daughter of the prime minister, she was originally rich and powerful, but she said to the emperor during the draft, "I will make this country strong" and was regarded as a madman and was thrown into the cold palace. The cold palace was in ruins, the food was rancid, and the maids and eunuchs bullied her and humiliated her. Everyone thought she was dead. Until she built a greenhouse on the wasteland of Leng Palace, refined steel, and made gunpowder. The eunuchs began to secretly call her "living god"; the generals begged her to improve their weapons; for a piece of steel from her in the court, aristocratic families and reformists almost spilled their blood in the Golden Palace. And the emperor who once didn't even bother to look at her, climbed over the wall and broke into her workshop late at night, and asked her with red eyes: "Shen Zhiyi, how many things do you still have that I don't know?" She wiped the engine oil on her hands and said expressionlessly: "Your Majesty, don't block the light, I am doing experiments." This is the story of a science student using knowledge to reduce dimensionality to attack an ancient dynasty. It is also a story about a scientific research maniac who was pampered from the cold palace to the top of power by a jealous emperor.
