[Fantasy world, slow-paced adventure, mage, monster compendium collecting] Transmigrated into a fantasy world, Gao Si gains an adventurer's handbook that grants power by killing and recording monsters—the more kills, the stronger he becomes. Expecting grand adventures slaying dragons and demons, he instead faces endlessly breeding goblins, pests that never die out. As his goblin kill count and rewards skyrocket, he grows increasingly exasperated: 'You have slain 1000 goblins! Intelligence +1, Strength +1, Constitution +1.' His title evolves from 'Goblin Slayer' to 'Goblin Expert' to 'Goblin Nemesis,' making him the most feared enemy in goblin history.
