Breaking the Boundary of Immortals and Demons

Call me a demon cultivator? No problem. Then use my fists, my sword, and my gun! Trample all of you **bugs to death without sparing any one! Even this world, I want to turn it over! But before that, why does this crappy system keep reminding me that the battery is low every day? I don't have a sect or breeding skills, so how can I get so much money? T.
