I'm in a Siheyuan, but the System Is in the World of Cultivation

[Siheyuan] + [Misaligned System] + [Inventions] + [Promotions] Zheng Yang transmigrates into Love in the Courtyard and gets bound to a System. But the System is in a different time and space from him, having gotten lost and stuck in the cultivation world. It even gives him missions: [Slay the wailing old hag of Myriad Ghost Mountain!] [Kill thirty bloodthirsty demon beasts!] [Create a superior spirit field to strengthen your body and replenish your vitality!] [Build a flying boat for travel!] Zheng Yang is dumbfounded. What demons and monsters could there be in the mortal world these days? Doesn’t it know that after the founding of the nation, spirits aren’t allowed to cultivate into monsters?! Then he slaps Jia Zhangshi for throwing a tantrum and hitting people. Mission complete, and he gets a top-grade spirit stone as a reward, though it turns into premium flour as soon as it reaches his hands. He swats thirty mosquitoes to death, successfully slays demons, and gets his reward. He clears a small vegetable patch in front of his home and successfully creates a spirit field. There’s no spiritual energy, but the vegetables are exceptionally high quality. A divine-grade weapon-forging manual from the cultivation world arrives in the mortal realm and is directly converted into a top-tier factory technology handbook! While everyone else in the courtyard bickers and schemes against one another, Zheng Yang uses his misaligned System to advance through technology and steadily build up his assets. No cultivation, no supernatural powers, no getting rich and carried away. Starting as a lowly apprentice, he turns the tables and crushes every despicable neighbor in the courtyard, seizing the opportunities of the times and forging his own path to greatness!
