In Shrek's inner courtyard, inside a very ordinary house built against the Golden Tree, waves of scorching heat kept spreading out. And this was a building shielded by the Golden Tree's aura-concealing power. That alone showed how high the quality of the power inside was. When the essence of one's power was high enough, it could break through restrictions; Huo Yuhao could do that now too, only the amount of aura he could leak was different. His quantity was too small.
The Evil Fire Phoenix was one of the highest-grade beast martial souls, its quality close to that of an ultimate martial soul. Its potential was great enough, and his predecessors had proven that point. Yet it had one fatal problem: it was not stable enough. This did not refer to the random instability of inheritance like with a Body Martial Soul, but to the instability the martial soul caused in the Soul Master. It was extremely easy for them to suffer cultivation deviation.
This limited the number of people with this martial soul. Not many people could control such an extremely powerful martial soul. As long as it appeared, it would absolutely never be weak. It was just that many people went mad during the process of growth. In theory, this martial soul was even stronger than the Blue Lightning Tyrant Dragon, as long as the problem of its stability could be solved.
It was not as if there had never been an owner of Ultimate Ice in history. It had indeed been able to effectively ease the martial soul's instability. Unfortunately, he had died young, and no one knew how he died. Everyone only needed to know that just as the Evil Fire Phoenix clan had begun to show promise, they lost the capital they needed to rise.
