李世民 / Li Shimin
李世民 / Li Shimin appears in Qinji 131-2 as one of the actors who pushes 李渊 toward rebellion against 杨广. The episode presents him beside 裴寂 rather than as the later emperor in his own right.
His source role is to make the drinking story strategic. Li Yuan’s drunken exposure is not enough by itself; Li Shimin and Pei Ji interpret it as an irreversible danger and convert that danger into a founding-rebellion argument.
