Clawed dragons were already a very strong type of main dragon.
It was possible that Blackie's evolution to World Emperor/Divine Kingdom would enable it to surpass the category of main dragon species to reach a new life rank for dragon species feys.
Lin Yuan and Spring had not yet discussed Blackie. Hence, Lin Yuan did not have an estimate of how Blackie's bloodline would evolve. He had no choice but to wait for Blackie to evolve until he did a comprehensive analysis of it.
Based on the level of Blackie's bloodline, Lin Yuan would be able to make a general estimate of the Sky Beyond the Clouds' level of dragon-species fey bloodline. This would be very important in helping Lin Yuan to understand the species in the Sky Beyond the Clouds.
