Sung Jin-Woo is an anomaly in the world of Solo Leveling. Unlike other hunters who are bound by a certain level limit, he is chosen by the mysterious live interface called the System. This gives him the ability to level up infinitely in strength without restraints, making him the strongest being in the series.

While every other hunter in the series has a certain level limit that can only be broken through a rare second awakening, Jin-Woo has no limiters to his powers. Let us explore in detail why, despite being a weak E-Rank Hunter, Jin-Woo was chosen by the System as its Player.

Sung Jin-Woo started in Solo Leveling as an extremely weak E-Rank Hunter who struggled endlessly to survive in a harsh world full of deadly monsters. In this world, all Hunters have a set level limit that they cannot cross without a very rare Double Awakening.

However, Jinwoo was chosen by the System to be its Player during his first trip to the Double Dungeon. During this dungeon raid, Jin-Woo's party was overwhelmed by monsters, and he chose to stay behind and sacrifice himself so his party could survive. Fighting until his final moments, he activated the hidden quest reward called Courage of the Weak.

Jin-Woo accepted the reward as he had no other options to survive, making him a Player of the System. This gave him access to multiple exclusive features, such as special quests, a personalized leveling system, unlimited inventory, access to rare items in a virtual store, and dungeons designed for him to level up rapidly.

This set Jin-Woo apart from the rest of the Hunters in Solo Leveling, making him the strongest being in the series. Unlike other hunters, he could increase his strength endlessly and, with powerful items at his disposal, defeat anyone in his path. The Architect, the creator of the System, was responsible for Jin-Woo being chosen.

The System is a magical program created by the Architect, the hidden boss of the Double Dungeon. It was designed to create the perfect vessel to inherit the power of Ashborn, the King of the Dead and Monarch of Shadows. The chosen individual had to be physically and mentally strong enough to withstand Ashborn's power.

The Architect created the System and the Double Dungeon quest to challenge and evaluate all Hunters, helping Ashborn find his perfect vessel. Considering this program was created by such a powerful entity, it is no surprise that it provided Jin-Woo with an infinite power boost, making him humanity's strongest Hunter.
