Blackie had already awakened its dragon-species bloodline and had evolved into the Spirit-Drawing Ichthyosaur.
The evolution to Fantasy Breed would grant a one-time qualitative leap, where the innate dragon-species bloodline would be completely unleashed.
It allowed Blackie to transform into a genuine flood dragon-species fey.
Although Blackie's bloodline would also improve tremendously, it did not need to endure much pain because it already had a solid foundation. It had already experienced agony in several stages when it evolved from Bronze grade and had only just awakened its dragon-species bloodline.
Thus, Blackie was all but settled and did not need much concern from Lin Yuan.
However, this was not the case for Genius.
Genius' evolution from an ordinary housekeeping beast to what it was now had not brought any obvious changes.
This opportunity to evolve to Fantasy Breed was a good chance for Genius to utterly transform itself.
