it seems the strongest job is not hero

One possible reason is that the concept of a 'hero' in a novel is often idealized and not based on real - world job skills. Jobs require practical skills, experience, and knowledge that may not be as glamorous as the heroic deeds in a novel. For example, a doctor's job is to save lives through medical procedures, not through superhuman feats like in a hero novel.

A wizard could be one. They might have vast magical powers that can change the course of events in ways a hero can't. For example, they could teleport, cast powerful spells to defeat enemies en masse, or even manipulate the elements on a large scale.

Well, perhaps in this light novel, the author is trying to subvert the common trope where the hero has the most powerful job. There could be a job like a mage or a thief that has some unique skills or advantages that make it stronger in the context of the story's world. For example, a mage might have the ability to control time or space, which could be more powerful than a hero's brute strength. And a thief could have stealth abilities that allow them to get in and out of dangerous situations unnoticed, giving them an edge over a hero who might be more straightforward in their approach.

Engineers are strong jobs. They use their knowledge of science and math to design and build things like bridges and buildings. It's not like the hero in a novel who just uses magic or super strength to solve problems.

There's a possibility that an ancient and legendary figure holds the strongest job. Maybe someone from the past, with a long - lost lineage related to dragon knights, has the purest form of this job and is the most powerful. This character could be a mystery in the story, only revealed as the plot unfolds.

Well, in many such novels, the strongest job often has superior combat abilities. Maybe in 'from the strongest job of dragon knight novel', it could be having extremely high physical strength, allowing the dragon knight to withstand powerful attacks. Also, they might have some unique skills related to dragons, like being able to communicate with them on a deeper level or having a special dragon - based attack that can cause massive damage to enemies.

The strongest hero in Invincible Heroes 3 was uncertain because there were many powerful heroes in the game, each with their own unique skills and attributes. In the game, the conditions for victory not only depended on the strength of the hero, but also many other factors such as the number, quality, skills, and tactics of the army. Therefore, the strongest hero in Heroes 3 depended on the situation of the game and the player's strategy.

I misunderstood your question. The Strongest Idler in History did not have a clear ending because it was an unfinished work that the author had no intention of completing. The novel was originally written by the author, World Champion, in 2013 and the first outline was released in 2017. However, due to the author's personal reasons and changes in his creative plan, this novel is still in the state of being written. Therefore, although you may have read some chapters, we cannot guarantee how the novel will end.

I don't have enough information to say who exactly 'Strongest Hero Shion' is. Since I'm not familiar with the specific novel, it could be a character created by the author with unique powers and a backstory.
