I Get a Portal from the Start and Dominate Another World

Tang Xian has lived on Blue Star for ten years since transmigrating there, when he suddenly gets bound to a Portal System. He hands the system straight over to his country and brings tanks, cannons, and other modern goods to a fantasy world. The land there is lush and beautiful, with birdsong and fragrant flowers. Gold and oil are everywhere, and the people of that other world are rich. Armed with Blue Star's goods and cannons, they plunder the local economy. Cultivator 1: "Holy crap, this isn't a syringe, it's a divine artifact that can inject spiritual energy straight into your blood!" Cultivator 2: "Holy crap, these instant noodles are amazing! They smell even better than spirit beast meat." Sect Elder: "Sect Master, a wicked disciple offended those Longguo people. Their fire sticks can kill cultivators from a distance. There's nothing we can do!" Sect Master: "What is that thing flying over there with a long tail trailing behind it?" The sect is wiped out!
