I am Lu Datou, a frail, chronically ill man who never goes anywhere without his medicine. A twist of fate brings me to Ying Zheng's side. Drawing on knowledge from the future, I expose the conspiracies of traitorous officials and corrupt ministers at court, uncover Lü Buwei's embezzlement network, and present a comprehensive plan to eliminate him. I offer strategies to help Qin Shi Huang unite the Nine Provinces. I seek neither high office nor great wealth; I only hope that after Great Qin unifies the realm, the wars will end, the people will live in peace, and ordinary citizens will be treated well. Ying Zheng regards me as a trusted confidant, and together we clear the obstacles at court and establish an era of peace and prosperity.
