Political Surrender Cascade / 招降示范级联
Political surrender cascade / 招降示范级联 is the pattern Qinji 128-5 builds from 蒯彻’s advice to 武臣. A rebel commander can sometimes take territory by making surrender look safer and more profitable than resistance, then letting nearby cities copy the first successful example.
The episode’s concrete mechanism is visible reward. Wu Chen sends Kuai Che with vehicles, cavalry, and noble seals to receive Xu Gong, so surrender is not merely tolerated; it is publicly validated. Once that case is known, more than thirty cities in old 燕国 and 赵国 territory surrender without battle.
This is not the same as battlefield victory. It depends on social proof, fear of isolation, and credible promises under conditions where Qin local authority is already weakening. In this source, the same mechanism helps Wu Chen expand fast enough that his base can later become a separate Zhao-centered interest inside 反秦阵营诸侯化分裂.
