(No Spoilers) Just saying, as someone who read a lot of the novel and is now rereading it, I keep seeing a lot of people who say that the author is copying Arifureta and Solo Leveling and that the concept is trash, but if you were actually not stupid you would see some major flaws in that. Later on in the story, (granted it does take quite awhile) it becomes completely original, and something only slightly similar to the other two. Even at the beginning, you can already see that the author has a plan for this novel, and it is definitely going somewhere. (Spoilers Ahead) If you were looking into how it becomes original, he eventually has to create his own interconnecting network of mana veins, something unrelated to the other two previously mentioned stories. He has to do this by getting a wise grandmaster to teach him (another original thing) and he finds the expert in another world.
