Thousands of years of clouds and mist have shrouded the sky, and the secrets of heaven are like a mystery. Wen Sheng was originally a casual cultivator, but due to a sudden "returning soul catastrophe", he destroyed his spiritual roots, leaving only half of his soul wandering around the world. Everyone thought his fate was doomed, but he glimpsed a crack in everything in the mist and found that his soul actually resonated with the lost mysterious ancient formation. In order to solve the mystery of his life experience, Wen Sheng embarked on the road to find the formation, but was repeatedly hunted by various sects because he mastered the truth of the forbidden technique that could subvert the three realms. Every step is like being trapped in a mirror, the authenticity is difficult to distinguish, only the sound of Sheng in the heart remains. Wen Sheng does not seek to ascend to immortality, but only wants to break through the fog, find out his true heart, and awaken the soul of the world that has been sleeping for thousands of years.
At the intersection of fate and truth, how will he use his remnant soul to uncover the source of the "Returning Soul Catastrophe"? When the fog clears, will the truth of the world be more cruel than the illusion? This is a dialogue between the soul and the world, a question about self and the universe.
