Lin Chen, an ordinary modern college student, travels back to the Kingdom of Wu during the Three Kingdoms period after an accident. Without a golden finger or systematic support, he struggled to gain a foothold in the land of Jiangdong with only modern knowledge reserves and vague memories of historical trends. Faced with the power struggle within Soochow and the complex game with Shu and Wei, Lin Chen started from the grassroots level and used a pragmatic vision to improve farming, organize officials, and advise on military affairs. He tried to use modern thinking to awaken the enterprising spirit of Jiangdong's monarchs and ministers, and planned a unification path for Wu that was different from historical facts at historical nodes such as the Chibi Beacon Fire, Jingzhou Storm, and Yiling Sunset. This is an ordinary person who uses knowledge as a sword in troubled times to write an alternative legend of himself and Jiangdong on the turbulent stage of the Three Kingdoms.
