It could be that the anime's pacing and plot requirements led to a downplay of Leorio's strength. Sometimes, to keep the story flowing smoothly, certain character traits or abilities are adjusted.
To be honest, I don't know for sure. Sometimes it might be feasible, but it often depends on the rights and regulations associated with that particular manhwa. You might want to look into the terms and conditions provided when you got it.
Well, usually it's possible, but it might involve certain conditions. For example, if it's a subscription-based service and you haven't violated any terms, you might be able to. But if it's a one-time purchase or has specific usage rules, it could be more complicated.
Learning to understand and understand Japanese requires a certain amount of time and effort, depending on one's learning speed and hobbies. For beginners, it may take a few months to master the basic knowledge of Japanese such as pronunciation, grammar, and vocabulary. However, if one could continue to study and pay attention to listening training, it would only take a few years to be able to read and understand Japanese fluently. Of course, this required constant practice and accumulation.
