Lin Mo, a programmer who died suddenly while working overtime, was reborn as a poor scholar before the Yellow Turban Rebellion.
With a digital vision and strategy simulator in his hand, he was able to think in code and think in troubled times: soap started, farmed to strengthen the base, improved technology, recruited Zhao Yun, and recruited Zhang Liao.
In the gap between Yuan Shao and Cao Cao, he used institutional innovation and systematic management to quietly build a "Youzhou Iron Cavalry".
When the flames of war broke out in Guandu, the world was shocked to realize that this poor programmer had become a chess player.
