In the vast world of cultivating immortals, young Lin Yuan has been gifted with extraordinary talents since childhood, but he always feels that all his cultivation and growth are controlled by invisible clues. By chance, he glimpsed the "cracks" in the world and discovered that the reality was nothing but a cage of fantasy. This is a virtual fairy space built by mysterious beings, and all living beings are puppets. Lin Yuan's awakening aroused the vigilance of the system's will, and he fell into the dilemma of being hunted and excluded. He teamed up with Chu Yao, who was also awakened, and under the complex protection and contradictions of his master Xuan Ming, he began to decipher the origin of the virtual world. Along the way, they encountered countless sniper attacks by Mo Yan and other guardians, met like-minded partners, and witnessed the disappearance and betrayal of their companions. Through layers of illusions and numerous levels, Lin Yuan worked step by step, gradually realizing that "thoughts are true", awakening more prisoners, and setting off a storm against the virtual world. In the end, Lin Yuan faced the ultimate temptation and threat of the system's will, made a choice on the line between life and death, broke the illusory prison, and led his companions to pursue true freedom. The novel uses ancient fairy tales as a carrier to describe the eternal propositions of human heart, freedom and truth.
