@Sullieman it does look like Goblin Slayer lol. And @Kyujyu don't get me started about that magician outfit, I'm pretty sure even by the standards of this manga's era, it's beyond outrageous ?
Why did he change classes again? If he could limitlessly buff attacks using production skills in battle as long as he has fuel then was there even a need to make a new character as a close ranger to fight space monsters?
@Memi The problem is he already reached the maximum level that the first crest allows, which sadly wasn't strong enough to fight what he wanted to fight, which were the monsters across the "Universe", a realm beyond the one he was fighting in. The fourth crest is a slow-burn type when it comes to levelling up, so it allows more room for him to grow. Think of the first crest as a perk that allows him to level up faster but get less points to allocate to skills, while the fourth crest is the complete opposite. Eventually, he'll outgrow the augmentations the first crest allows.
jfc he already saw his creations and he hasn't concluded that this is his world in the future? How the f did he solve those math problems with that brain.
AND THOSE GIRLS ALREADY KNEW HE HAD MAGIC STORAGE WHY ARE THEY SURPRISED
