The Leader of an Empire Who Started Out As a Goblin

Transmigrating to another world and becoming a goblin, Ivan possesses a special shield: Hunter. From small insects to humans and elves, and even giant dragons and demon kings, he gains a specific ability from each one he kills. But considering his own weakness as a goblin... Ivan thought he was destined to spend his life in the dark goblin cave, nibbling on fleshy rice bugs and slowly growing old... until he saw more and more human adventurers arriving. Hunting male human warriors grants warrior skills like Spin Slash! Capturing female human mages increases the number of goblins he breeds by +10. The green-skinned dwarf, slaying those who resist and sparing those who surrender, quickly builds an invincible goblin army! From goblin berserkers, goblin shamans, goblin priests, to mecha goblins capable of crafting explosive weapons...
