A Zhu traveled through time and became a peasant girl who was living in poverty and was about to be sold to a landlord as a concubine. The only dowry was a "heavenly book" that fell from the sky and almost killed her. After opening it, A Zhu was silent. Postpartum care for sows, on the correct ratio of reinforced concrete, detailed interpretation of the construction drawings of the Three Gorges Dam... Is this book a bit too hardcore? At first, she just wanted to build a new pigsty so that the whole family could eat meat. Later, when she saw that the villagers had to walk a three-mile mountain road to carry water, she silently took out the water conservancy map and built a diversion canal. Later, facing the floods that occurred every year, she gritted her teeth and spread out the map to a group of sallow-looking victims: "Let's build a dam?" Everyone said: "???" From then on, a strange woman appeared in the Zhou Dynasty. The noble ladies in the capital were admiring flowers and composing poems, while A-Zhu was directing the mixing of cement at the construction site; the princes and dignitaries were vying for power, and A-Zhu was planning a nationwide chidao network; the enemy army was pressing on the border, and the court was in chaos. A-Zhu silently opened the thirteen uses of gunpowder and handed it to the general beside her who had silently supported her from the beginning. The general/future emperor, His Majesty Xiao Heng, felt hot in his heart when he looked at the gray-faced girl with astonishingly bright eyes in front of him, as well as the city rising from the ground behind her, and the roads and bridges connecting the world. "A-Zhu, I'm the one to be hired, are you willing to be my queen?" A-Zhu wiped the sweat from his face and looked up at the sky: "Don't worry, wait until I build the Qinghai-Tibet Railway to your door first." Xiao Heng: "... Okay." This is a story about changing the world without magic, relying entirely on knowledge, and talking about love at the same time.
