Monster Absorber

A boy who loves games related to monsters gets reincarnated into a world filled with magic and monsters. A special system is within this new realm and has given the citizens skills along with magic. The boy found that the system gave him nothing in the field of magic or damaging skills. The only thing the system gave him was one skill, taming. So the boy travels the new world, taming and researching all types of monsters, living his life in bliss... but not everything can be blissful.
