Sunlit Shadow Dance was separated into three main parts: the Ethereal Step, a foundational movement technique. A set of 16 different offensive and defensive techniques that seamlessly blended in the form of connecting strikes like a dance called Flowing Sequence. Lastly, The final part is called Unbending Eclipse which could be called an ultimate technique of the scripture. It's the culmination of all the previous techniques. It required the mastery of the Flowing Sequence to execute a devastating combination of offense, defense, and suppression.
The first part, Ethereal Step, intrigued Xu Qi the most. Not only because it was the only technique he could practice at the moment but also because movement techniques were often undervalued compared to offensive or defensive skills. Many believed that as long as you learned a decent one, you could get away from dangerous situations.
