In a'reverse world novel', one key feature could be the inversion of social norms. For example, the roles of the rich and the poor might be reversed, with the poor having all the power and luxury while the rich struggle. Another feature might be the reversal of natural laws, like gravity working in an opposite way. Also, moral values could be reversed, where things considered bad in our world are good in the reverse world of the novel.
I'm not sure specifically as I haven't read it in detail. But generally, it might involve adventures related to the immortal sword in a reverse world. There could be battles, quests for power, and encounters with various strange creatures or characters.
I'm not entirely sure about the specific plot of this novel as it might be relatively unknown or not widely read. But generally, it might involve the adventures of an immortal swordsman in a reverse or alternate world. Maybe he has to face unique challenges, like strange creatures or different rules of magic and combat compared to a normal world.
The settings are often very distinct. They might have reversed magic systems or social hierarchies. Like in some, the lower class in our world could be the ruling class in the reverse world, which creates a lot of interesting plot points for the story to explore.
The plot might center around the journey of this immortal swordsman in a reverse world. He could be facing challenges that are unique to this world. For example, if in a normal world, good is rewarded and evil is punished, in this reverse world, it could be the opposite. And the swordsman has to navigate through this complex and strange world, perhaps to find a way to restore balance or seek his own truth.
I don't really know since I haven't read it. But usually, there would be a protagonist who wields the immortal sword. There might also be a mentor - like figure who guides the protagonist in the reverse world.
The main character is surely the immortal swordsman. There could be other important characters around him. Maybe there's a female character who serves as his love interest or a partner in his adventures. There might also be an old sage - like figure who gives him advice or guidance in this reverse world. And of course, there could be villains, like powerful warlords or dark mages who oppose the swordsman and his quest in this strange world.
I'm not sure about the exact plot as I haven't read it in detail. But generally, it might involve the adventures of an immortal swordsman in a reverse world. Maybe he has to face unique challenges and enemies that are different from the normal world.
Since I haven't read the novel, I can't say for sure. But surely the immortal swordsman is one of the main characters. There may also be other characters like his friends or foes, perhaps a mentor figure who guides him in this reverse world.
One main theme is the exploration of the 'other'. Since the world is reversed, it's like exploring an alien yet familiar place. It often makes readers question what they consider normal.
