I Am the Protector of the Devil in the World of Immortality

After traveling through time and becoming a handyman in the immortal world, Lin Ran was bound to the Demon King's protection system - every time he broke through a realm, he transformed into a mythical figure to protect an era. He is Sun Wukong who protects Tang Monk, Zhang Liang who assists Liu Bang, Zhuge Liang who supports the Han Dynasty, and Yue Fei who is upright and turbulent. The first copy was only rated B: "You protected the story, but failed to protect the regret of the incarnation." Until he picked up a small beast in the back mountain - the body of Qilin, the son of heaven. The whole world wants to refine it to mend the sky, but he is the only one who holds it and is the enemy of the whole world.
