On a parallel Earth facing resource depletion and climate crisis, the World Will initiates the National Destiny Game, binding the fate of nations to the performance of three randomly selected contestants. For Xia Country, the stakes are incredibly high: two elite warriors, Bai Yuekui and Hua Mulan, are chosen alongside an unexpected captain—Liu Bei, an ordinary otaku with no combat skills. While his teammates bring gold and weapons, Liu Bei shockingly arrives with nothing but sprouting potatoes, causing global mockery and national despair.

However, the game world is the war-torn Late Han Dynasty, where famine reigns supreme. In a twist that silences critics, the system awards Xia Country double grain production for bringing the high-yield crop, revealing Liu Bei's seemingly absurd choice as a strategic masterstroke. Now, tasked with leading his team through the chaotic Three Kingdoms era, this unassuming protagonist must leverage his historical knowledge and unconventional resources to build a faction, survive deadly conflicts, and secure his nation's destiny against all odds.
