System: Sorry, I’m a Farmer

What? The boiler exploded? More than a hundred people dead? But what does that have to do with me, Gao Jun? Wait a second, I'm the one who runs the boiler. Holy crap... The System came riding in on the flames, catching me completely off guard. This is bad~ Huh? The System actually wants me to grow crops? No problem. I'll send my medicinal herbs all over the world. The world changes, spiritual qi revives, and supernatural abilities run rampant. It all starts with me.
