Dasaide could no longer maintain his composure because Long Yi's words directly hit his weak spot! Here, he couldn't obtain Dragon Power from his contract dragon! And in fact, the Power of Rules in the vicinity was continuously absorbing his Fighting Aura!
Contrary to common belief, the amount of Fighting Aura a Dragon Knight has does not increase with their rank. The majority of Dragon Knights have a very limited quantity of Fighting Aura their body can store. Even a powerful Dragon Knight like Dasaide, who has nine Dragon Marks, only means that he can unleash more powerful Fighting Aura attacks; it does not mean he has more of it.
Typically, Dragon Knights are always together with their contract dragons and can draw upon an infinite supply of Fighting Aura. Who cares about how much Fighting Aura they have then?
