Review Detail of jinmorifan_2 in In A Cultivation World With The Highest Intellect

Being a genius doesn't make them perfect, they just think very differently. So no, not every genius out there would have a contingency plan for their death. He already found a way to increase his lifespan and thought that would be enough. Knowing that he is better than everyone, and knowing that his demise wouldn't benefit humanity, he felt safe. Being the best made him arrogant so he completely ignored the extremist factor, and that is what led to his untimely death.
