What exactly is a 'System' in the context of webnovels, and how does it differ from 'Cultivation'?

In webnovels, a 'System' typically refers to an external, often magical or technological, interface that grants the protagonist special abilities, quests, and a way to track their progress. Think of it like a game interface overlaid onto reality. The protagonist might receive points, skills, or even new bodies through the System, and often these abilities are acquired through completing tasks or overcoming challenges presented by the System itself. It's a very direct and often rapid way for a character to become powerful. Examples can be seen in novels like "Worldwide Simulation Era" where the 'System' tag suggests such an element is present.

Cultivation, on the other hand, is a more traditional martial arts and fantasy concept, often seen in Xianxia novels like "I Came From The Mortal World". It's an internal process where characters train their bodies, minds, and spiritual energy to achieve greater strength, longevity, and often, immortality. Cultivation involves mastering techniques, understanding qi or spiritual energy, and progressing through various realms of power. While both systems lead to increased power, Cultivation is usually more about personal discipline, natural progression (albeit enhanced by training), and understanding fundamental energies, whereas a 'System' is more about external guidance and structured power acquisition, often with a more game-like feel.
