I'm not sure specifically as I haven't read it. But generally, a web novel with 'otherworldly hero business' might be about a hero's adventures in a different world, perhaps involving battles, quests, and character development.
Well, one interesting point could be the unique concept of the hero's business in the otherworldly setting. It might bring a fresh take on the traditional hero story, perhaps with different types of transactions or quests that are related to the hero's role in that world.
In many light novels, the concept of an otherworldly hero is common. The 'circle' could refer to a group or a specific place in the other world. When it comes to business, the hero might engage in trade, like using his unique skills or knowledge from his original world to start a new business in the otherworldly setting. For example, he could use modern marketing ideas in a medieval - like other world. This combination creates interesting plots and character development.
The 'circle' can also be seen as a network of opportunities for the otherworldly hero in the business sense. As a hero, he has unique access to resources or knowledge that others in the other world don't. He can use this to his advantage in the business world. For example, if he has the ability to understand ancient languages, he could discover valuable business secrets or artifacts within the 'circle' and use them to build his own business empire while also fulfilling his heroic duties in the other world.
The concept of an otherworldly hero offers a sense of escapism. Readers can imagine being transported to a new and exciting world. The 'business' aspect adds an interesting layer. It could be about building a kingdom, managing a guild, or trading unique items in the new world.
One popular title could be 'That Time I Got Reincarnated as a Slime'. It features an otherworldly adventure where the protagonist becomes a slime and builds his own 'business' of sorts in the new world, making allies and growing in power.
