In the Xuanchen world, where thousands of races compete for the throne, the human race was once the glorious master. However, due to a "disaster of breaking the road" that swept across the world, the path of cultivation was broken, and it became a vassal of all races, struggling on the edge of survival. Ling Chen, a young man, was born into the humblest class of "dust people" in the human race. He was born with blocked spiritual veins and was regarded as a waste with no possibility of cultivation. However, by accident, he discovered an ancient jade slip full of cracks in the family's forbidden area, which actually contained the complete Taoist tradition of the heyday of the human race - "The Jue of All Things Returning to Dust".
From then on, Ling Chen used dust as his foundation, used his mortal body to defy heaven, and rose up step by step amid ridicule and killing. He repaired the broken road, awakened the sleeping human blood, and explored the truth of the "Broken Road Disaster" in a desperate situation. Faced with the devouring of monsters, the temptation of demons, and the contempt of ancient tribes, he held a rusty sword in his hand and carried the future of mankind on his shoulders. He walked out of the dust and finally became a Taoist master, uncovering the unprecedented shocking secrets of the Xuanchen world and letting the glory of mankind shine in the heavens again.
