- Description from novelbuddy

For five years, I've lived the life of a failure. Smashing my hands against the wooden target in hopes of entering a meditative state; a necessary step to becoming a cultivator.For five years, I've faced nothing but disappointment, looks of pity, and meager attempts at encouragement.But everything has to come to an end. An end, that for me, became a new beginning!Circuits, wires, and capacitors? Or maybe spirit powder, Spricur crystals, and Qi gathering formations?In a world where cultivation is, for most, merely a hobby and the worlds of mysticism and science are divided, I shall be the one to craft a bridge between the two!Why rely on ancient arrays to harness dense Qi? Isn't it easier to buy one of my converters, plug it into the wall, and be done with it?Is your gaming console malfunctioning, yet no tech shop can find the cause? Have you tried this the exorcising swatter 3.0?And you! Yes, you, the one whose reflection appears on the screen on your phone once you block it! Why would you buy static figurines if you can come to my shop... And get your hands on waifus that will actively flirt with you?Come all ye troubled souls, and allow this God to craft a solution to all your problems!
