Honestly, I've been reading 'The Immortal Invincible' for months now on that serial platform, and I'm still not 100% convinced the guy the story follows is the real protagonist. His name's Lin Feng, obviously, the classic 'trash' cultivator who gets a second chance after a betrayal. But the narrative feels like it spends as much time, if not more, on the heavenly dao, the ancient wars between cosmic factions, and this recurring motif of a chessboard where cultivators are just pieces.
Lin Feng's progression is insane—he goes from getting beaten up in a backwater sect to challenging primordial beings within a few hundred chapters—but his personality often feels like a vehicle for power-ups and face-slapping arcs rather than a deeply explored character. The real 'protagonist' might be the concept of invincibility itself, or the system of cultivation that the novel dissects in obsessive detail. I keep reading for the sheer scale of the worldbuilding and the inventive realms, not because I'm deeply invested in Lin Feng's personal journey. He's more of a guided tour through a ridiculously expansive mythos.
