League of Legends Shadow Assassin: Another World

A top assassin was betrayed by his partner during an assassination mission and came to a different world with all his memories. Invasion of Noxus, Ward of the Firstborn, Zaun, Shurima, Ixtal, and the Void. . . Can an ordinary person with modern memory and assassination techniques make a small splash in this bizarre continent? Open a bank and become the top rich man? Develop science and technology and push society forward for decades? Practice magic and use your strength to unify the entire continent? What? Can't achieve these? Then I'd better think about how to find my way home. . .
