As for why he didn't use the Heavenly Dragon Blood Essence as the main material, it was still because the highest-level resources might not be the most suitable. Mu Xuan had already tried just now. If the Heavenly Dragon Blood Essence was used as the main material, it would evolve into the dragon race!
Mu Xuan already had a dragon beast, so he naturally didn't want the Void Dragon Polecat to also become a dragon beast. In this way, the resources would be wasted.
"Roar!" The Ice Crystal Frost Dragon looked at the Void Dragon Polecat that was about to evolve and specially roared, as if it was reminding Mu Xuan that it could continue evolving.
Mu Xuan touched the Ice Crystal Dragon's cold head and said in embarrassment, "Little Spirit, you still have to wait for your resources…"
"Roar…"
At this moment, an extremely dense energy fluctuation erupted from the Void Dragon Polecat's body, attracting the attention of Mu Xuan and the three beasts.
