In the twenty-fifth year of Jian'an, Lin Yan, a top modern strategist and doctor of science and engineering, passed through his soul and became Liu Chan, the prince of the Shu Han Dynasty. At that time, Liu Bei had just proclaimed himself emperor, and the foundation of the Shu Han Dynasty was just being established, but it was full of crises. He empowered logistics with science and technology. From Adou, who was ridiculed and unable to support him, to unifying the Three Kingdoms, Liu Chan spent his life interpreting "I am happy here, why do I miss Shu? What I think about is destroying Wei and prospering Han!", And wrote a legend of rejuvenating the country through science and technology and reversing the Three Kingdoms.
