Invincible immortal

After dying in a tragic accident, Sol Kim expected nothing but darkness. Instead, he opened his eyes in the body of Kai Valen, the disgraced second son of a noble family in a world ruled by magic, monsters, and dungeons. In this world, strength is everything. Those who fail to reach the First Star are treated as worthless. And Kai Valen died trying. Burdened with the memories of his predecessor and trapped in a world he doesn't understand, Kai must learn how to survive among powerful nobles, deadly dungeons, and ancient secrets buried beneath five hundred years of history. But on the day of his rebirth, something awakens. A mysterious system. A forgotten legacy. And a path that should no longer exist. While the world believes the age of legends ended centuries ago, Kai is about to discover the truth behind the lost stars, the sealed gate, and the power that vanished from history. Follow Kai Valen as he rises from the weakest magician to a being beyond the limits of this world.
