This is Twelve-Winged Dark Seraphim's newest work and it's very good. At the beginning I felt like the MC was too powerful and wished he had more of a humble beginnings but as time went on it wasn't much of an issue. This author excels at telling adventure stories and this whole story is an amazing adventure. The MC is very strong and often has to go out into the wilderness alone to improve his strength and hide his secrets. The best part of this story is following a free-spirited MC. He's very grounded in his personality and realistic but he travels around with restraint. I think that was a large part of the reason Super Gene became so popular and you will get more of that in this novel.
