Paper Ashes Lin'an, Snow Spreads Across Jiangnan

What can an investment banker who only knows how to settle accounts do if he travels back to the late Southern Song Dynasty? He clearly knew that this dynasty had less than twenty years left, and he had no golden finger, so he wrote the "Salvation Plan" and then watched it be burned and watched everyone around him die one by one. Is he a failure? In a practical sense yes. But he is also successful. His success lies precisely in the courage to do it even though he knows that nothing can be done, and the persistence to stick to it even after knowing that the outcome is determined. I want to give you a solitary lamp to illuminate the dark room from thousands of years ago, and that's enough.
