No. 'Manhwa' is a form of Korean comic or graphic novel, and it's not something that can be eaten in a literal sense. And in the context of leveling up in games or personal growth, consuming a manhwa novel as food is an absurd concept and has no real way of contributing to leveling up.
At level 40 in Maple Story, you should consider joining a guild if you haven't already. Guilds often organize group activities like guild quests which can reward you with a large amount of experience. Farming for rare items in specific areas can also be beneficial.

The event - specific tasks usually give a boost to your leveling progress.
In Restaurant Story, constantly upgrading your equipment and decor can also help you level up. New and better equipment can speed up cooking times, allowing you to serve more customers in less time.

Moreover, fulfilling special customer requests is a great way to earn extra experience points. These requests usually give a significant boost to your leveling progress.
'Log Horizon' is also a top - notch level up light novel.

They would get sick or worse. Since manhwa novels are not food, trying to eat them would cause choking, digestive problems, and could even be life - threatening. There's no way it could lead to leveling up in any sense.
'Steins; Gate' can be a good choice too. It has unique scientific and technical terms as part of its plot, expanding your vocabulary in those areas. The dialogue is well - written and can expose you to different sentence patterns in Japanese.
