At the Xiao family martial arts training ground, sixteen-year-old Xiao Chen was undergoing the annual cultivation test. In front of everyone, he tested out that he only had the third level of body tempering cultivation, which attracted ridicule from everyone in the family and the contemptuous eyes of his fiancée Lin Qingxue.
- After the test, Xiao Chen went to the cliff of the back mountain alone to vent his emotions. He accidentally triggered the ancient restriction and fell into a mysterious cave.
- In the cave, Xiao Chen found a mysterious ancient ring and a jade slip recording the "Burning Heaven Art". Sleeping in the ancient ring was a remnant soul who called himself "Yan Lao"
