Xiao Zheng and dryads.
Zheng was a war orphan. His parents were killed by samurais in a small village near the Ulsan castle. But Zheng was saved by two dryads. The cruel fact that Xiao Zheng personally witnessed the death of his parents heavily influenced Zheng. Meanwhile, dryads intended to utilize Zheng to achieve their conspiracy, expanding their magical forest near the Ulsan castle. Dryads secretly trained Zheng, imparting assassination skills and nature magic to Zheng.
