Background / History

Li Si serves among Qin's highest ministers beside Wang Jian and Wei Liao. A Legalist associated with Xun Zi's school, he is described as Han Fei's fellow disciple and senior brother. His fief is Shangcai, though he claims no recollection of a blacksmith there when Wang Jian raises the subject. 36 37 269 325

During Qin's preparations to conquer Han, Li Si proposes a double-layered strategy: a surprise assault from Nanyang to seize Han swiftly while Wang Jian feigns engagement with Zhao, exhausting Zhao's strength for a later campaign. Ying Zheng approves the scheme. 37

Li Si later travels to Shuofang and tries to arrange Jiang Ling'er's marriage to his son, Li Meng. Ling'er rejects the proposal because she is betrothed to Wei Zhe, and Li Si responds with threats. 57

His rivalry with Wei Zhe repeatedly damages his position. Li Si attempts to use Wei Zhe's rewards of women and gold as grounds for a corruption charge, but Wei Zhe reframes them as imperial strategy and exposes Li Si's motives before the court. Li Si collapses under the reversal and is demoted to a minor censor. 111 112 113

Ying Zheng subsequently instructs Li Si to watch Wei Zhe, calling Li Si a blade needed to restrain a subject whose power is growing difficult to control. Li Si delivers this warning personally, only for Wei Zhe to answer that he is not the sword but the one wielding it. 130 131

Li Si later assists the political purge surrounding Wang Wan's downfall. In the Heavenly Prison, he presents Wang Wan with a confession from his son Wang Xi and reads the decree sentencing Wang Wan to death by a thousand cuts and the extermination of nine generations of his family. 266

• Has a thin face and deep-set eyes. 36

Personality

Li Si is calculating, articulate, and deeply committed to the authority of Qin law. He can turn legal principle into a political weapon, whether calculating Wei Zhe's extraordinary military merit or publicly challenging the imperial clan over criminal accusations. 49 130

His ambition is paired with insecurity. He seeks influence through marriage arrangements, factional maneuvering, and attempts to ingratiate himself with Han Fei, yet he becomes visibly shaken when confronted by Wei Zhe's growing power. 57 113 275 280

Li Si is also ruthless when he has the advantage. He dismisses imprisoned former colleagues with contempt and takes evident satisfaction in Wang Wan's despair. 266
