According to the plot you provided, I recommend a novel called "Cultivation Begins in the Desert" among ring novels. The main character of the book, Zhou Hong, was sent to a sect when he was young. He had a strange farming interspatial ring that could be used to grow spiritual herbs, refine spiritual pills, cultivate magic power, strengthen his physique, and work hard in cultivation. There were all kinds of immortal cultivation resources stored in the ring, which could allow the protagonist to continuously increase his strength. I hope you like this fairy's recommendation. Muah ~😗
