Plot Relevance
Zhuang Yuan was the first disciple of Lu Xinwen, along with the only disciple to attempt to assassinate He Quanxin. Since his cultivation was also 10th Layer Houtian, they were almost evenly matched, apart from the elemental difference, giving He Quanxin an advantage higher than just the slight Internal Energy difference.

Although he escaped from He Quanxin, He Yiming followed him and later killed him in Book 2, Chapter 42.
