😋According to your needs, I recommend the following two novels:
1. " Full-time Hunter's Soul Hunting Twin ": The protagonist from Earth transmigrated to the Hunter World and became a novice hunter. He needed to become a powerful hunter through his own efforts and understanding of Soul Hunting, leading everyone to defeat all kinds of enemies.
2. " Witcher Witcher ": The protagonist was lost in the mutation of the source power and transmigrated to the mysterious ruins world. He carried the game composer and became the servant of a small hunter. After becoming a witcher, he had to pursue the ultimate mystery and eliminate the monsters that were about to invade humans.
The above is my personal recommendation. I hope you like my recommendation.
The key elements include the diverse ecosystems where the monsters live. Each ecosystem has its own characteristics that affect both the monsters and the hunters. Also, the role of the guilds is important. They organize and regulate the hunting activities, train new hunters, and preserve the knowledge about monsters. And the concept of progression for hunters, as they gain experience and better equipment through successful hunts.
The background story of Monster Hunter is set in a world filled with various large and powerful monsters. Hunters are trained individuals who take on the task of hunting these monsters for different reasons. Some hunt for resources like monster parts which can be used to craft better weapons and armor. Others do it to protect their villages from the rampages of these beasts. It's a world where the balance between humans and monsters is constantly being maintained through these hunts.
The Hunter x Hunter manga is unfortunately not complete. The author has faced various issues that have led to intermittent breaks and an unresolved storyline.
