Sung Jin - woo is a character who is constantly evolving and becoming stronger in the 'Solo Leveling' novel. He has a lot of abilities that set him apart, such as his shadow - based powers. Goto Ryuji, on the other hand, is not as prominent. He doesn't have the same level of development and power - up opportunities as Sung Jin - woo. Also, Sung Jin - woo is at the center of the story's plot, with his actions driving the narrative forward, while Goto Ryuji is more on the periphery, not having as much influence on the overall story.
Well, Sung Jin - woo is the protagonist with a really remarkable journey in the 'Solo Leveling' novel. He starts from being a weak hunter and gradually becomes incredibly strong. Goto Ryuji doesn't have the same kind of character arc. Sung Jin - woo has his shadow powers which he can use in very creative ways in battles, while there's no indication that Goto Ryuji has any such distinct or powerful abilities. In terms of their importance in the story, Sung Jin - woo is central, and Goto Ryuji is just a side character with much less impact.
Sung Jin - woo in Solo Leveling has the ability to level up, which significantly increases his stats and powers. He can also summon shadow soldiers, which is a very unique and powerful ability. As for Goto from the novel, since we don't know which novel he is from specifically, we can't really compare directly. But if Goto doesn't have the ability to create minions or rapidly increase his power like Sung Jin - woo, that would be a major difference.
Well, it's quite possible. 'Solo Leveling' has a large following, and if there is a novel version, it would likely cover the events of chapter 71. But you need to check the official sources or fan communities to be sure. Sometimes there could be differences in the pacing or additional details in the novel compared to the webtoon.
I don't have the exact chapter number off the top of my head. But you can usually find it easily by doing a quick search on popular online novel communities or dedicated Solo Leveling forums.
It's hard to say for sure. Different platforms and sources might have different chapter counts. Try looking on popular novel reading platforms or asking in related online communities for the most up-to-date chapter information.
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.
