Lin Fan was the male lead of the novel " Reborn City's Master Immortal ". The story was about Lin Fan as an Immortal Reverent. After his rebirth, he returned to the city and faced all sorts of challenges and the persecutions of his enemies. He worked hard to change the unfairness of fate. He had displayed great strength in the city, defeated Evil, and gradually rose to become an existence admired by everyone. Lin Fan's story was full of exciting and intense plots, bringing great pleasure to the readers.

😋I recommend the following two novels to you: Self-taught Cultivation and Interstellar Mecha Cultivation. The former was an urban supernatural novel, in which the protagonist was framed and could not join the cultivation army, but chose to become a self-taught expert in the cultivation world, while the latter was an interstellar love song novel in the sci-fi space, in which the protagonist used cultivation methods to strengthen his spiritual power and drive a mecha to protect his family and friends.

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.

Proud Martial Sword God had the main character, Ning Buhui.
