Liu Yuan, a deliveryman who saved a cat on a rainy night, traveled through the smoke-filled Korean battlefield in 1951 and possessed the body of Liu Huaiyuan, a young soldier of the same name. When he was on the verge of death, he not only merged with the memory of his original body, but also accidentally bound a mysterious thousand-square-meter space containing the "Basic Body Refining Technique" and Qi Refining Pill. After recovering from his injury and returning to China, he moved into a courtyard house in Nanluoguxiang with a "simple" atmosphere.
Faced with the calculations of the moral god Yi Zhonghai, the provocation of the violent war god Silly Zhu, and the blackmail of demons and demons, Liu Huaiyuan, who has cognition and extraordinary abilities beyond his time, smiled calmly. His fists and kicks can make the "God of War" of the quadrangle doubt life; his methods can turn the whole hospital meeting into a joke; his pattern has already jumped out of the square and settled on the top of the magnificent wave of the times.
From anonymously submitting key technical ideas to using space to rescue endangered cultural treasures for the country; from laying out southern trade to accumulate capital, to making waves in the international financial market in the future. Liu Huaiyuan's goal has never been just to be the "master" of the courtyard. And at the starting point of all this, the daughter of a returned doctor named Lin Xiaoyue was looking at him with her calm and firm eyes, becoming his warmest companion in the long years.
This is a story about freedom, protection and rise. Let's see how Liu Huaiyuan can not only protect his family to live comfortably in the courtyard in this turbulent era, but also act as a behind-the-scenes hand to accumulate strength for the country and ultimately stir up the world.
