Ego
Ryu's body, under the control of his Dao Heart, thrummed with undying momentum. Its gaze flashed and its body split into countless clones.
It began to roll through the rest of the Fiend army as though they were nothing more than weeds on the ground.
The more Ryu watched this, the calmer he seemed to become. But this calmness felt like the greatest danger.
It was numbness.
Numbness to his situation. Numbness to the understanding that even now, he wasn't all that special. Numbness to the realization that in the end, he was a slave to his emotions.
Why was his Dao Heart reacting like this? It boiled down to two reasons.
First, his Incorporeal Souls had matured independently of each other. It could be said that there was more than one Ryu in this life. The problem was that only one of them carried his "Ego".
This Ego was not his pride, but rather his consciousness.
