I recommend "I've Become a Cultivation Cave" to you. This is a fantasy novel about an otherworldly continent. It tells the story of an otaku on Earth who accidentally falls into a cultivation cave and successfully becomes a cultivation cave. He then discovers the secrets of Earth in the cave. In this process, he obtained great power and subdued a demon. This book was full of ups and downs, and the plot was attractive, bringing countless surprises and insights to the readers. I hope you like my recommendation. Muah ~
