Has there ever been a CN novel where Modern Transmigrators actually used modern knowledge to gain an advantage over their, relatively speaking, primitive aboriginal counterparts? I mean, I'm not a scientists, I'm just an ordinary civilian but the logic of how Guns works isn't exactly rocket science. Some things you can probably replace with cultivation elements. Like, why would you want to be a swordsman? or use a bow and arrow? Fuck, I'd spend my time figuring out how would I go about making a shotgun(short range), assault rifle(long range), and a few grenades(for when you are clichedly surrounded). With those alone, I'd probably dominate those in the mortal realms. Not to mention that you can most likely evolve said weapons further down the beaten cultivation path. Imagine an Immortal wielding machine gun, just firing wantonly upon your enemies. I'd probably attach one to my flying spirit beast and go brrrrrr upon my enemies. I feel like the path I've described above is a more realistic depiction as to what would happen if a Modern person were to be transported to a relatively ancient cultivation world.
