The Eternal Snake expressed the results of its hibernation through its hiss. Marcella could partially evaluate the nature of its new power, but what she failed to understand left her confused.
The creature was still a rank 9 magical beast in the upper tier. Its species had undergone some changes, but there were limits to how much it could improve.
Marcella had seen magical beasts overcoming their innate limits through transformations and modifications, which often involved a radical evolution of their species. For example, the Foolery had to become a hybrid, and the dragons had to turn themselves into mindless weapons.
Even Noah had to go through a similar process multiple times during his life. He had started as a human and had walked the hybrid path for many years until he had eventually surpassed that entire field.
However, the Eternal Snake didn't do any of that. It had remained a magical beast, and most of its core still shared many similarities with its original species.
