Interracial Lovers Enter the Battlefield

As an avid lover of different races, will you travel to another world one day? Do you fantasize about how to use your knowledge to live a "quiet and elegant" happy life with cute people of different races? Only then did I realize that past knowledge, experience, and logic were of no use in this seemingly familiar and rapidly developing world. How do hundreds of ethnic groups seek medical treatment? Should Elf's sentencing amount be doubled? Is the life of the demons also life? Although the "ability" given by the gods is powerful, it also makes him the focus of the world and puts him in danger, forcing him to go to the place he hates the most - the battlefield.
