Back to 1910: Building America's Greatest Mafia

I Traveled Back to 1910 with a Business System... and Accidentally Built the World's Greatest Empire. An antique stopwatch. A strange old man's warning. A one-way trip to 1910 New York. With nothing but the Founder's Ledger, Ricky must survive gang-controlled docks, build businesses from scratch, recruit loyal allies, and invest in the inventors who will change the century. Money earns influence. Influence shapes nations. And without realizing it... Ricky becomes humanity's greatest insurance against its own future. — Description from novelcodex.org
