I recommend the three books, Array Cultivation, Pill Formation Master, and Martial Dao Hegemony. " Formation Cultivation " told the story of how a good-for-nothing used formations to become one of the most powerful cultivation methods. The description of formations was very interesting. << Grandmaster of Pill Formations >> was a story that combined pill refinement and array formations. Pill refinement compressed 999,999 array formations to refine a Primordial Spirit Pill. The pill formed a world of its own. The content was compact and the plot was full of ups and downs. " Martial Arts Dominator " was a story about the protagonist who was proficient in medicine, pills, and arrays. He was an all-rounder and became the supreme martial artist through long-term hard work. I hope you like my recommendation.
