All for one
While the guardsmen's own spiritual energy felt like a nice and cool free-flowing stream of water, the foreign energy presented itself as a small fish made of pure light that was swimming through it.
Hao Xuan's spiritual sense reached out and entered their bodies without their knowledge. His own soul was strong enough to overpower them completely if he so desired but he chose to keep it on the down-low.
To the guardsmen, this invasion of their bodies did not appear outright threatening. All they saw was Hao Xuan's bright green eyes staring down at them in silence. They could not force themselves to look away and fell into a sort of a trance.
The surroundings became darker and darker while Hao Xuan's shadowy silhouette became larger in their eyes, bearing down at them like to a great mountain.
