A Billionaire Creating His Modern Empire in Another World

John Richard who is a bored 27-year-old billionaire buys an uninhabited island. When he explores the Island with his bodyguards, they found a cave and explored it but the cave brought them to a world where goblins, elves, beast-men, kings, and knights exist.

After seeing this John said these words, " I'm going to make this a new playground for myself. I will create a kingdom far superior to the ones existing here, with the help of technology."

Will he become a conquerer or someone who will help improve this world?
