In the mysterious Nether City, Yun Zhao and the man in black started a fateful contest that spanned time and space around Yujue. While Yun Zhao was exploring the mystery of Yu Jue, he discovered that behind it lay the Nether City of three hundred time and space, as well as the intricate fateful entanglement between himself and the man in black robe. As the story progresses, Yun Zhao gradually uncovers the mystery of the blood-moon pattern left by his mother, as well as the conspiracy of the man in black robe to tamper with time marks and extract spiritual veins. In the confrontation with the man in black robe, Yun Zhao not only had to face the chaos of time and space and the replacement of memory, but also faced the fate and choice deep in his heart. In the end, Yun Zhao relied on his control of the blood moon pattern and nine-star disk, as well as his deep understanding of fate, to successfully break the cycle of reincarnation and save the time and space controlled by the man in black robe.
