If you want to find more fantasy novels, they usually talk about warlocks, Taoism, etc., Which give people a feeling of being far away from our lives but close to them. For example, the weird things that usually happen are actually caused by something we can't see.
The first book is highly recommended. After reading the second book, I got cold sweats. The third one is more suitable for those who are timid but want to read horror novels. After reading the fourth book, I felt like a mental patient.
