In a border area between the desert and the grasslands, Xu Tie led a hundred Iron Skinned Men to crush a large number of sand scorpions into pulp.

Each sand scorpion could provide him with at least 0.001 units of Plane Essence.

After killing tens of thousands of sand scorpions, Xu Tie finally gathered 10 units of Plane Essence.

Using up this Plane Essence, Xu Tie communicated with the Divine Realm through a golden bracelet and retrieved a black ceramic jar.
