Lin Wei, a female doctor of engineering, died one day, and her soul was transformed into Lin Wei, a young man from a poor family who had a poor family and was heavily in debt. The memory of her past life became her only golden finger. Let's see how she uses her left hand to make soap and modify farm tools to alleviate the current famine; with her right hand, she draws mind maps, prepares for scientific exams, and enters the imperial examination officialdom. Starting from the county trial case, she turned modern scientific thinking into the practical knowledge of "studying things to gain knowledge", repairing water conservancy, setting up factories, fighting disasters, and fighting against powerful officials. This road she walked was unique and lonely. When he became successful and famous, everyone in the world lamented that he was a lonely man despite being a great minister. Only he knew that the thousands of miles of mountains and mountains he created and the magnificent "Gewu Tongjian" were his most romantic answers to this other world.
