“The Underworld Realm” is Boris Romanovsky’s novel, the sixth book of the “Delta” cycle, genre: reincarnation fantasy, bojars’-anime, RealRPG. I returned twenty-two years into the past to change the future. The Original World is a place where every person can begin their evolution in one of several directions—of course, if they survive. Fighting monsters and killing them, people evolved: purifying their DNA and developing the abilities they gained. I carry a huge responsibility, because only I know what awaits this world. I can become its salvation, or its doom.
