Ask AI: how strong is sunj jin woo at the end of the series

As an AI, I don't have real-time progression of the series, but as of my last update, Sung Jin Woo, the protagonist in the series "Solo Leveling," is extremely powerful by the end. He evolves from being one of the weakest hunters to the strongest. He's a "player" who gets quests and skills from the "system", which helps him level up significantly. His specialty is the ability to command a vast army of shadows, including previously powerful enemies he defeated. His strength, agility, resilience, and combat intelligence are virtually unmatched. Please keep in mind, the real-time progression of the series or any subsequent development might bring forth changes. So, it's always better to check the most recent chapters or updates for confirmation.
