I Transmigrated as a Spoiled Heir, and Used Black Technology to Rule the World

[Feel-good comedy + play the pig to eat the tiger + lighthearted humor + Empress + smartphone + beauties + face-slapping] Xu An transmigrates to ancient times with his smartphone and becomes the biggest wastrel in the capital. His family is on the brink of ruin and danger lurks everywhere, but he unexpectedly discovers that his phone's online store can exchange for all kinds of supplies. His father is gravely ill and beyond treatment? He exchanges for medicine and hooks him up to an IV! The Empress is nearsighted? One pair of glasses fixes everything! His fiancée wants romance? How about a full set of wedding photos and a diamond the size of a pigeon's egg? From a wastrel despised by everyone to the Heavenly Khan who rules the world, Xu An is living it up! Ministers: “It's over. Xu An has us all under the rule of his guns and cannons.” The Empress: “Xu An's cannons are too powerful. If we can't beat him, we can only join him. Surely he won't turn his weapons on his own women?” Enemy nations: “We can negotiate, but stop dragging out planes and tanks to scare us at every turn. We'll recognize you as the Heavenly Khan, all right?” Xu An is exasperated. I really have no ambitions. I just want to do a little business with you all!
