Eren pondered over the existence of the legendary Celestial Dragon. Uncertain of its actual existence, he couldn't help but imagine the immense power it would possess.
The question that intrigued him even more was the strength of the person who could kill such a formidable creature, especially in the Dragon's Domain.
"If only I possessed that level of strength," Eren mused, "I wouldn't have to worry about taking down a mere Sea Dragon."
Reflecting on his past accomplishments, Eren remembered his encounter with a Poison Dragon. However, he understood that the circumstances were quite different.
The Poison Dragon was already weakened when he faced it, giving him an advantage. Furthermore, the nature of a Poison Dragon was distinct from that of a Sea Dragon, particularly one that resided in the vastness of the sea.
