After he finished reading the first few core techniques of the "Myriad Beast Totem", what was most important for Yi Yun was that he learned the method to evolving his Golden Crow Totem.
With the Purple Crystal Origins, it was not a distant objective.
The Purple Crystal activated and according to the description in the "Myriad Beast Totem", Yi Yun extracted the Power of Desolates from the metal-winged eagle. Soon, a fist-sized beast mark appeared. It was a lively-looking little beast and its body emitted rich pure Yang energy as it quickly flew into Yi Yun's dantian.
The metal-winged eagle did not have any obvious nomological elemental properties. Its Yuan Qi was not as effective as pure Yang Yuan Qi to Yi Yun, but the effects were not that different.
Feeling his "Myriad Beast Totem" improve a tiny bit and his pure Yang body and Aspect Totem also obtaining a tiny bit of nourishment, a look of satisfaction appeared on Yi Yun's face.
