My Heaven-Defying Shop: Buying the Martial God Realm from the Start

After transmigrating into a high-martial-arts world, Lu Yuan has spent eighteen years training hard, yet he remains stuck at the third level of Body Tempering. The whole school agrees he is a good-for-nothing. Both his parents are innate-level powerhouses, and his older sister is a peerless prodigy at a top martial arts university. He alone has bottom-tier talent, and with the martial arts entrance exam just three months away, his future looks bleak. Just as everyone assumes he is destined for mediocrity and will have to spend his days in the liberal arts class, the heaven-defying System, eighteen years late, finally comes online! Compensation for the System's delay: every item in the shop is available at a limited-time, heaven-defying discount! The pinnacle Martial God Realm normally costs a billion martial arts coins, but now it can be purchased outright for just 10! After completing the beginner quest of doing a thousand push-ups, Lu Yuan pays in full for perfect Martial God cultivation! A max-level Martial God drops into the beginner village, with no rival left in the mortal world! The beginner dungeon, Azure Wolf Valley? One punch kills the boss, crushing every genius! A mutation in the abyssal rift, a Grandmaster-level ferocious beast laying waste to a city? He slays it with a flick of his finger and protects the city! A deadly, fated secret realm opens? He sweeps through all seven levels of danger at will and claims its peerless opportunity for himself! He leaves divine pills, divine gear, and top-tier techniques for his family, helping his parents reach Grandmaster rank and his sister ascend to the pinnacle of martial arts. Together, they defy fate and change their family's destiny! The martial arts entrance exam arrives. Geniuses gather, prodigies emerge, and countless people mock the good-for-nothing, certain he'll come in last. No one knows that Lu Yuan is already the world's only Martial God. He takes the exam quietly and casually enrolls at Kunlun Martial Arts University, just to experience student life and keep his sister company. As beast tides engulf cities, ancient secret realms emerge, and powerful factions battle for supremacy in a chaotic age... Lu Yuan silently watches the world contend. With the shop at his fingertips, he roams the land, steadily completing his perfect Martial God foundation and forcefully overturning the entire high-martial-arts era!
