Set in a fantasy world with equally incredible characters, our hero, Liu Ming, works his way through years of spiritual growth and martial arts achievement to gradually become far more powerful than he ever expected. In Demon's Diary Book II, Liu Ming continues along his cultivation journey in the Barbarian Ghost Sect, learning more about the world of the sects while working towards becoming a Spirit Apostle. Although Liu Ming is still labelled a Three Spiritual Pulse disciple incapable of successfully cultivating to become a Spirit Master, Liu Ming proves to everyone that he is a force to be reckoned with — many heads start towards the young man with the help of his mentors such as Zhu Chi, Scholar Gui, Martial Aunt Zhong, and a couple of unexpected elders and sect disciples from within the sect. Nicknamed the "Mission Man," Liu Ming puts himself on the board by completing various sect missions by utilizing new techniques and spells to gain more experience and expand his skill set. Liu Ming slowly gains acceptance and praise from the people around him with each mission and battle event, but with the Large Competition on the horizon, how will Liu Ming move up the ranks and ultimately prove his self-worth?
