Sixteen-year-old Shen Qingci, a legitimate daughter of the Duke of Zhenguo with a modern soul. On the surface, she is a naive and lazy person who only likes talking books and snacks. On the inside, she is a wise and foolish traveler with a complicated heart. She originally wanted to live a stable life, but because of the military sketches she left behind, she attracted the attention of the cold-faced war god Jing Wang Xiao Jue.
In order to protect himself, and to retain the modern feelings of family and country in his heart, Shen Qingci secretly started a business under the pseudonym "Liu Li Gong Zi" and established the intelligence and business empire Liu Li Pavilion. A piece of paper conferring marriage binds two people who have their own thoughts together. From the "cooperative marriage" to the life-and-death dependence of going south to control floods, she gradually shed her disguise in front of Xiao Jue, and he was deeply attracted by the amazing wisdom and tenacity under this lazy appearance, and a secret love arose.
When the court was divided, foreign enemies coveted, and the budding industry encountered many obstacles, the couple worked side by side. She ignited the industrial revolution with her knowledge that transcended the times, founded the "Gewu Bao" to enlighten people's wisdom, and promoted the birth of steam engines, railways, telegraphs and even ironclad ships. He used his military power and skills to clear obstacles for her and protect her from moving forward.
From pretending to be a salted fish to taking charge of national weapons, Shen Qingci spent ten years dragging ancient beams into the industrial dawn with faltering but firm steps. And Xiao Jue, the once cold and strict God of War, was willing to be her strongest support throughout his life, shouldering the weight of an era with her. This is a story about love and ideals, protection and change, which together write a legend in the torrent of history.
