Translation isn't the greatest in this novel, after reading through 90 chapters, it require some brain power. The author or translator is pretty bad at math, the math seem pretty bad or it could be a riddle? no idea.
-similar to other dungeons/gates/hunter etc. novels, the mc is pretty much similar to a summoner, except he only summon difference types of goblins so far from a fallen goblin kingdom after he became their lord. Of course he still have to find the goblins in other crack "dungeons" so he can gather them together in Ashvilam. He doesn't care about the goblin in the begin but later he decided to help them rebuild Ashvilam kingdom and find out some history/truth to what happen to the kingdom/goblin "sarahon" race.
Spoiler below if u want to save brain power,
enjoy reading ~
