What are some common themes or plot devices found in webnovels about transmigration or reincarnation?

Transmigration and reincarnation are incredibly popular themes in webnovels, and they often come with a predictable yet satisfying set of common elements. One of the most frequent is the protagonist gaining knowledge or abilities from their past life, which they then use to navigate their new world. This is particularly prevalent in isekai (another world) stories where a modern person finds themselves in a fantasy setting. They might use their understanding of science, history, or even pop culture to their advantage, often leading to them becoming exceptionally skilled or influential very quickly.

Another very common device is the 'system,' often presented as a game-like interface that grants the protagonist quests, skills, or power-ups. This is especially seen in genres like 'System' novels or those that blend fantasy with gaming elements. The system acts as a guide and a source of power, accelerating the protagonist's growth. When it comes to reincarnation, revenge is a very strong motivator for many protagonists. They may have died unjustly or suffered greatly in their previous life, and their primary goal in their new life is to exact retribution on those who wronged them. This often leads to a 'villainous' or anti-hero protagonist who isn't afraid to use ruthless methods to achieve their aims.

The concept of 'overpowered' protagonists is also rampant. Whether through transmigration, reincarnation, or a sudden awakening of latent power, many characters quickly become far stronger than anyone else in their world. This can be a wish fulfillment aspect for readers, allowing them to see a character effortlessly overcome challenges. Additionally, many stories feature the protagonist hiding their true strength, operating from the shadows while subtly influencing events or preparing for a grand reveal. This creates suspense and allows for dramatic moments when their power is finally unleashed. Finally, romance is almost always a component, often featuring a harem for male protagonists or a strong, fated love interest for female protagonists, with the protagonist's unique circumstances often making them irresistible.
