Age progression novels follow the lifelong journey of a protagonist, often starting from birth or early childhood and spanning several decades. This tag is a staple of cultivation stories and epic fantasy, where readers witness every milestone of a character’s physical and mental development. Common tropes include the 'reincarnated infant' hiding their true power, rigorous sect training, and the eventual transition into a powerful elder or ancestor. Fans love this genre for its deep sense of character development and the immense payoff of seeing a weak child evolve into a world-shaking powerhouse. Whether it involves a slow-burn slice of life childhood or time-skips through centuries of meditation, these stories offer a uniquely satisfying perspective on the passage of time and the accumulation of wisdom and strength.
