Lin Yuan, an orphan, struggled to survive in a world eroded by turbid sources and ravaged by abyssal beasts. He accidentally awakened the world-devouring seed and became the final vessel carefully cultivated by the world-keeper Bai Wugou. He was originally a victim written to death by fate, but in the battles and losses, he rejected all preset endings. Together with Zhao Tieyi, who has carried the guilt of his sister all his life, and Su Xiaoxiao, who has escaped the fate of the artificial body, and other companions, he faces the truth of the experiment a hundred years ago, the purification conspiracy of the Master of the World, and the chess game Bai Wujia has laid out with fifteen years of obsession. In the end, Lin Yuan broke the binary fate of "sacrifice or destruction" and used the power of returning to the source to become a door connecting the two worlds. He protected the people he loved and the world in his own way, explaining that people always have the right to choose the third way.
