Which novels described the main character transmigrating to the West and becoming a monster?

The main character of the novel is an evil demon, the kind that eats people and kills people.

Answer 1

I recommend the novel," I Guard the Heaven Prison in the Journey to the West," to you. It was written by the author, San Wan Buchou. It's a Xianxia-Mythological Cultivation novel. The plot revolved around Li Anran becoming a heavenly soldier guarding the Heavenly Prison in the Heavenly Court of the World of the West. He had no background, no magic treasures, and his strength was average. By continuously suppressing criminals, he continuously received rewards and gradually grew into a powerful Heavenly Soldier. This was a cruel and realistic world. Immortals and Buddhas were free and unfettered, while the heavenly soldiers and generals were like cows and horses. I hope you like my recommendation.
