A Hero Who Knows His Stuff

After spending two decades in another world fighting monsters, Hyeonseok finally s쳮ded in saving it and was rewarded with a return to Earth. Now going by the name Chanseok and working as a former deliveryman, he looks forward to the comforts of modern life. However, Earth is nothing like he remembers. Monsters now emerge from randomly appearing Erosion Points, and those born with special abilities become Hunters to combat them. Reluctantly, Chanseok applies to become a Hunter himself—mainly for the money. After all, he's already saved one world; how tough can saving another be?
