This sea-demon elephant had naturally developed its own methods of survival and cultivation to reach the early stage of Body Integration. Faced with Lu Xiaotian forcibly tempering its soul, it resisted fiercely despite its fear.
Fortunately, Lu Xiaotian's Primordial Spirit was already far stronger than that of the sea-demon elephant before him. No matter how wildly it charged about within the sealed space, it could never escape Lu Xiaotian's control.
