Back To 1370: Establishing The Federal Reserve

I traversed back to 1370, to Lübeck, a city in Germany. Lacking the expertise of a scientist, I could not bring the steam engine or industrialization to life. Instead, I took the scholar's route, establishing the Federal Reserve, just for the fun of it.
The Hanseatic League, guilds, clubs, The Three-Body Problem, stock exchanges, futures contracts, stocks, paper currency, Napoleon's artillery tactics... these are the gifts the protagonist offers to the ancients.
This novel revolves around the ultimate goal of establishing the Federal Reserve, with the creation of paper currency and credit as the central mission. Each plot is steeped in business warfare and profit-making, filled with numerous case studies of commercial conflict that demand careful thought from the reader. Be forewarned, this book is intellectually stimulating—dare to take the challenge.
In The Three-Body Problem(A 2008 novel by the Chinese hard science fiction author Liu Cixin ), the Dark Forest theory suggests that resources are finite, yet the expansion of civilizations knows no bounds.
The protagonist also assists his brother in rising from a mere baron to the Emperor of the Holy Roman Empire.
