What novels about cultivating immortals are written in line with the traditional metaphysical system of cultivating immortals?

Just dream into the machine (Buddha is the Tao), which has always been guided by traditional myths. The story unfolds with the disorderly entry of the protagonist Zhou Qing, which is very interesting. There is also a movie (Ask Hunyuan), in which the protagonist crosses, and Hong Jun, the ancestor, is in the same era. It's ingenious and worth seeing.
