The vampire young lady made a sound argument, but when facing divine beings, having a sound argument doesn't always allow you to refuse some requests.
Natalie has indeed just become the chosen of the God of Nature, but her powers are still in the growing phase, and Avalon doesn't dare to grant her too much divine power in case it overwhelms Old Feinock's daughter.
However, the divine power seed within Phemys doesn't have this issue.
As long as the young lady cooperates, Avalon can continuously apply the great power of nature onto the battlefield through this seed.
For instance, right now, the young lady, who originally wanted to summon a meteor to retaliate, had to interrupt her spiritual energy. She spread her enormous wings to hover in the air, holding a magic wand in her left hand while forming a cross symbol with her right. Then, the crimson seed inside her started to vibrate, and wild natural psychic power spread outward with her as the center.
