Hwang Hui served FOUR kings and lived to 89 in an era where that was basically immortality

This man was prime minister for 18 years straight and served under Taejong, Sejong, Munjong, AND Danjong. He was known for never taking a strong stance on anything — his colleagues called him 'the slippery prime minister' because he'd just nod along in meetings. But that's literally WHY he survived four reigns when everyone else was getting purged or executed. While other ministers were dying on hills (literally), Hwang Hui was just vibing and making quiet compromises. He retired at 87 and died at 89. In the 1400s. The man figured out the meta before anyone else.
