"Damn, you truly are something else," Five muttered, still feeling the shock of the day. He had come to understand what merging two auras really meant. It was harder than it seemed.
First, most people wouldn't spend their time comprehending a second aura after already mastering their first. Even if they did, in most cases, they would fail to comprehend a second aura.
However, there were still instances where some learned a second type of aura, but that was as far as it went. They would either focus on the first one or completely abandon one after finding it impossible to balance both.
Humans had limited time, and they could only focus on one thing at a time.
Therefore, in such a situation, very few people would even think about comprehending another aura, let alone merging two of them.
