As Jiang Fei had always faced opponents that were much stronger, he needed to be protected by the women around him.
Under such circumstances, his ego would always be affected. This was very much the case for Jiang Fei who was still in the prime of his youth. Initially, Jiang Fei's comprehension toward the Power of Conqueror was to make him infinitely more powerful. With such a Unique Domain, Jiang Fei could continually enhance his capabilities. Regardless of how strong his opponent was, Jiang Fei would always be stronger still.
In order to support such a powerful Domain, he would need to be supported by an energy core. Based on one's own powers, not a single Level 5 expert could do such a thing. Therefore, 0541 had suggested Jiang Fei to fuse with the Core of Life which was most beneficial for enhancing one's powers.
