The Tale of Immortal Cultivation

(Fast leveling early on + a normal pace in the middle and later stages + gradual growth in character)

In the cultivation world, the strong look down on all living things like gods, while the weak are no better than ants. Lin Yi was born into a minor family on the fringes of the world, and witnessed its tragic destruction. This planted in him a yearning for power. He vowed to stand at the top of the world and seek the legendary path to immortality.

P.S. (The protagonist is a character who grows over time. He levels up quickly at first, and the cruelty of the cultivation world gradually shapes his character. Later, he becomes decisive and ruthless, while making a clear distinction between gratitude and grudges.)
