The Protector Who Returned from Another World

This is the story of a royal guard from a steampunk world who does whatever he wants on Earth. [This book will incorporate some content from American TV series and movies, such as The Force of Evil, The Original Family, Bloods, Resident Evil, etc. Of course, the author is also a fan of console games. Some game content with excellent plots and complete world views will also appear, such as the Dishonored series, the Fallout series, and the famous Bioshock series. I will try to incorporate the world view in the book.
