The Techie's Artifact Refining System

As an engineering student, I was inexplicably dumped into the world of cultivation, where I joined a dirt-poor little sect that couldn't even make decent magical artifacts.

The sect leader, standing beside the spirit-stone-powered temperature-control formation that was only for show and too precious to use: What on earth did you make?

The protagonist: A Gree air conditioner.

The sect leader, holding the sect's most precious low-grade spirit sword, which was used as a teaching tool: What on earth did you make?

The protagonist: Dongfeng 17.
