This story is not something completely new and has some "default" isekai concepts, but those are not boring or very predictable (When they are, it's not that annoying), and the characters are not "empty", so reading was quite satisfying.
Basically, MC very good at crafting-related magic as well as assassination (Having additional bonus due to overall knowledge level in the new world) and uses this knowledge to achieve his goals, balancing between crafting, negotiating, and fighting, remaining cold-blooded, as expected from an assassin.
Additionally, a certain amount of realistic character behavior makes the story more interesting, and enjoyable.
This manga is surely worth the time to read if the goal is to see more of the isekai genre.
