Noah didn't like that the quasi-rank 7 Eternal Snake had begun to eat its underlings. He also had an interest in those creatures since they were the best food for his current state.
His body had begun to approach the breakthrough to the upper tier, but Noah was aware of its insane requirements. All the creatures hunted in those years had only managed to push its power across one tier, and he had reached the point when his center of power would need even more energy.
That was a drawback that would accompany him for his whole life. A higher power required more energy to advance, and Noah knew that he had the best body available.
His recent project had also increased those requirements. His body had become even stronger after the fusion with the Snake's glands. The empowerment had raised the amount of energy needed for his breakthrough.
