MTL - C-class Hybrids Forced To Slay Dragons - ~ After the end of the book, I inadvertently created a biological myth civilization

A man who was once called the world’s strongest agent ended up becoming a teacher after his retirement, to train a new generation of agents. After many years of training his disciples, he was killed at the age of 60 by a secret organization’s ruse and was reincarnated in another world with his memories intact. Though he was surprised by the existence of magic and the strange species in that world, he quickly adapted to his condition as a newborn and took advantage of it. He acquired special magic and gained a massive amount of strength thanks to his rigorous discipline, in order to reach his goal: Resume his career as a teacher which he left halfway through in his previous life. This is the story of a man, who, based on the memories and the experiences of his previous life, became a teacher who travels through the world with his students.

It wasn’t even malicious criticism.I just gave feedback in the tone I was asked to.So why the hell did I, the writer who just wanted to help a junior, possess this body of the prospective groom… a villain, who died in the hands of the heroine on their wedding night?

In a world where Classes, Stats, and Levels are the everyday norm, Reivyn has a secret.He was unusually aware of his surroundings from an incredibly early age, and Skills and Stats were acquired easily. He was just the son of an ordinary village family, and nothing appeared out of the ordinary on the surface. But below the surface, dreams of another life help shape his mentality and growth. Why does he have some remembrance of a past life, and what is his purpose in this new one?“Soul of the Warrior” is what I call a Semi-Isekai LitRPG. I say “semi,” because Reivyn's past life is remembered like a dream, and very incomplete. It is still Isekai, though, as he remembers enough that it directly shapes his personality and his sense of self.The System that governs the world of “Soul of the Warrior” is a combination of modified versions from Selkie's “Beneath the Dragoneye Moons” and Kosnik4's “Magic Smithing.” I have changed enough of these Systems and combined them in a way that is unique that I'm mostly sure it's fine, but I still have requested permission to use these ideas. They have both graciously granted me permission.Winner of the April Writathon Challenge.
