I recommend "Cultivation Begins from the Heavenly Silkworm Transformation" and "One Man's Heavenly Silkworm Transformation." The former was a novel about the infinite heavens. Ye had experienced thousands of worlds and did not seek immortality but only to achieve enlightenment. The latter was a light novel, a derivative doujinshi novel. The protagonist inherited the Heavenly Silkworm Divine Skill that was admired by millions of people in the 500-year-old non-human world. I hope you like this fairy's recommendation. Muah ~😗
