Chimey's feathers were changing because its bloodline was transforming.
Chimey could have successfully transformed even without the Imagination Suzuki's tree stump and the eggshell of the Holy Light Lofty Phoenix. Now, with these two precious spiritual ingredients to support Chimey's bloodline advancement, Chimey's bloodline metamorphosis was a sure bet.
Lin Yuan could feel Chimey's pain in the light.
Chimey's body was constantly disintegrating and recombining. However, Lin Yuan could not help Chimey with its bloodline metamorphosis. He could only provide it with resources.
Sun Yin knew that there was a Grade 6 Creator presiding over Sky City but was unaware that the Grade 6 Creator resources that Lin Yuan had promised were actually produced by himself.
Sun Yin could tell that Lin Yuan was nervous about Chimey's evolution.
