Boom!
Ye Tianchen's "External Incarnation" was knocked flying, falling to the ground, and soon rose into the air again. His clothes were somewhat tattered, but this wasn't the real Ye Tianchen, so there were no signs of severe injury.
The magic of the External Incarnation lies in battling the opponent with it; as long as the caster is strong enough, it's sufficient to fight with the "External Incarnation" against an opponent. It doesn't get injured, it either continues the fight or is directly shattered into powder, dispersing into the air, making the opponent immediately realize it's not the real body, just the "External Incarnation."
