On June 12, 2135, Ling Yun woke up from his sleep and found that he was the only person in the world who had no memory of rebirth. When all mankind returned collectively with the bloody memories of the last ten years, frantically hoarding supplies and building forces, he was ecstatic when he saw the system interface that suddenly appeared in his mind - "The Picture of the Jiao Fu Huangquan", "The Prison-Suppressing Power of the Divine Elephant", "The Technique of Cutting the Sky and Drawing the Sword"... Countless legendary techniques and artifacts could be exchanged at will!
