Immortal Realm Learning Machine? But I'm on Earth!

After unexpectedly acquiring an Immortal Realm Learning Machine designed to aid in cultivation, Wang Cheng initially planned to share the secrets of immortality with the public and usher in an era of universal cultivation. To his surprise, no one believed him. Left with no other choice, Wang Cheng set out to prove that he could truly cultivate. When faced with a lack of spiritual energy, he simply earned enough money to manufacture his own, inadvertently creating the world's largest pharmaceutical company and curing numerous terminal illnesses. When faced with a lack of cultivation resources, he once again earned enough money to manufacture his own, accidentally building the world's largest materials technology company, the largest geomagnetic array, and the largest space array. When Wang Cheng finally stood alone in the vast expanse of space, he shouted to the world: "I really am cultivating immortals!"
