Half an hour later, Xiao Mu walked out of the warehouse smoothly.
The entire process of exchanging materials left him very satisfied.
At this moment, he had fewer than dozens of storage boxes, but he obtained the two main materials needed to upgrade the Blood Cloud Flag: Netherworld Bamboo and Netherworld Spring Moss, both of Grade A material.
These Grade A materials could at least upgrade the Blood Cloud Flag, a True God treasure, to the Fifth Grade, or even the Seventh Grade.
And Xiao Mu's current Blood Cloud Flag was merely of the Third Grade.
If he could upgrade it to the Seventh Grade, or even just the Fifth Grade, it would be enough for Xiao Mu to suppress the True God Realm.
With the materials in hand, Xiao Mu flew directly towards the direction of the Human Emperor Tower.
The Human Emperor Tower was located in the southwest direction of the Floating Sky Palace; about half an hour later, Xiao Mu reached the destination and landed.
