Review Detail of Sven123 in Weapon seller in the world of magic

I read this with an expectation of having a genius weapon maker create and modify modern weapons to dominate the cultivation world, and even creating a sci-fi level weapons with system assistance to compete with cultivation deities. Instead I was given a system that strong-armed the shopkeeper and limiting his creativity by only treat him as an assembly machine to produce a type of weapon with blueprint given by the system and forbidding him from doing any kind of modifications, totally ignoring his previously stated "Once in a century weapon maker prodigy". I am very disappointed.
