Overall, the Solo Leveling novel ends on a high note. The protagonist overcomes all the challenges and reaches a state of ultimate strength and victory. There are also some touching moments with his allies and a sense of closure for the story.
The Solo Leveling anime sticks closely to the manga. But there are instances where the anime might condense or expand certain events to create a more engaging viewing experience. The key plot points and character developments remain largely unchanged, though.
The story of Solo Leveling is about a weak hunter named Sung Jin - woo. In a world filled with dungeons and monsters, he starts off as an E - rank hunter, which is the lowest rank. But he gets a mysterious system that allows him to level up and become extremely powerful over time. He faces various dangerous dungeons and strong monsters, and gradually rises to become one of the most powerful hunters in the world.
I'm not sure exactly what happens in chapter 145 without reading it again. But generally, in 'Solo Leveling', each chapter is filled with intense battles and character development. It could be that the main character is facing a new and powerful enemy or achieving a new level of power himself.
