In the post-apocalyptic era, amidst the wasteland and chaos, the great path reaches the heavens. Mad Outer Gods, uncontrollable cursed cultivation methods, extraordinary martial artists facing ominous old age... Above the starry sky, deities circle, and below, ghosts roam at night! In this doomsday scenario, Xu Shu carries the "Primordial Scroll" and transmigrates. Through a simulation game, he achieves one exclusive accomplishment after another, seeking a sliver of hope for survival. The ten-day apocalypse, the Dragon King returns, resurrects his lover, and saves the world; With a passionate and generous heart, he fights and conquers while carrying the burden of a grieving father whose child was stillborn... As more and more accomplishments are achieved, he gradually lets himself go within the simulation game. Until... A true disciple of the Female Void Palace is pregnant overnight, announcing an emergency lockdown; The long-extinct master of the White Jade Capital rises from the grave, destroys enemies with a wave and proves his Dao as a Great Emperor; A shepherd boy arrives at the gates of the Holy Temple, claiming to be Ye Su; Moreover, a young man riding a cow attains enlightenment, leaving Hangu Pass and preaching with a scroll: - The human race must strengthen itself. You may admire me, but there's no need to worship me; - Together, we punish those who claim to be gods! ... Dreams reflect reality, and more and more people begin to spread his name and words across the land. Only then does Xu Shu realize that the life he simulated has far-reaching effects, like a butterfly flapping its wings! And those rampant Outer Gods finally recall the fear that once dominated them... He dies thousands of times on the path to ascension, and another night passes in the Primordial Scroll. Suddenly looking back, he has shattered both heaven and earth. "I, Xu Shu, am a crude person. My apologies, fairy!" ---
