苏秦
After the failure of the first vertical alliance, Su Qin eventually came to live in Qi, where he was favored by King Xuan and drew the envy of the ministers. An assassination attempt in 300 BC left Su mortally wounded but not dead. Sensing death approaching, he advised the newly crowned King Min have him publicly executed to draw out the assassins. King Min complied with Su's request and killed him, putting an end to the first generation of Vertical alliance thinkers.
