What is a "Self Grassman"?
The Self Grassman, also known as Clone Grassman or Ten Thousand Skill Grassman.
It belonged to the high order in the Grassman Skill.
It focused on strong controllability and strong expandability.
Based on the Reconnaissance Grassman, Divine Movement Grassman, and Powerful Grassman techniques, the caster could use the grassman as a clone to speak, observe, and even fight.
What was strong controllability? The things the Self Grassman could do were numerous, just like having a second body, something other grassman techniques couldn't achieve.
As for strong expandability, it could integrate all grassman techniques!
For example, the "Divine Movement Grassman" and "Powerful Grassman" techniques Zhao Xing currently practiced, if he continued to delve deeper, could be merged to create a "Divine Movement Powerful Grassman," or even combine three or four techniques.
