Lin Yu is twenty-two, the last cultivator in the modern world. No, the only cultivator, and an unorthodox one at that. In this age when spiritual energy is fading, he can only linger at the early stage of Qi Refining. Just as he gives up cultivation and prepares to enjoy life, he travels to a country where people are living pretty well and kills two local thugs who try to rob him. After refining their souls into the Human Emperor Banner, his stagnant cultivation unexpectedly begins to improve. (In truth, the artifact his unorthodox master gave him on his deathbed was the Soul-Refining Banner, but Lin Yu just likes calling it the Human Emperor Banner.) He discovers that the banner can connect him to the national fortune of the modern world. Through it, he can also contact the First Emperor of the ancient Qin dynasty, now in his twilight years, and assign him missions. The rewards are manifested through national fortune and delivered directly to the First Emperor through the banner. Lin Yu is effectively a System, a national-fortune System exclusive to the First Emperor.
