Are there any novels on Novelblur where a character transmigrates into a world with a system that enhances their abilities, similar to RPG mechanics?

Yes, there are several novels on Novelblur that feature transmigration and system mechanics, often blending fantasy and action. For instance, "Arriving in the Naruto world by filling out a form" places the protagonist in the Naruto universe, where a transmigration form seems to have initiated his journey with enhanced capabilities. While not explicitly a 'system' in the traditional RPG sense, the premise implies a structured enhancement of his new reality.

Another excellent example is "Project Seraphina [LitRPG, Magitech, GL]". This novel directly incorporates LitRPG elements, suggesting a system that governs abilities and progression. The protagonist, Seraphina, discovers she can merge magic and technology, hinting at a system that likely tracks and enhances these powers. The description also mentions a 'mysterious System' awakening on Earth, which is a strong indicator of system-based progression. These novels often explore how characters adapt to new worlds with established rules and power structures that are often game-like in their design, offering players or protagonists clear paths to growth and power.
