Chapter 2538: Attack of the Alien Insects!

One after another, mobile castles popped up from the sand.

The Source Sand told Lin Yuan through their spiritual energy link, "Each granule of the Overlord Sand is a core that controls a mobile castle. All that is required to produce a mobile castle is a radium structure, and it will automatically move on its own using the movement of the quicksand. It will only use up the energy in my body when they are attacking. However, I can ensure that every mobile castle has Suzerain power!"

The Source Sand's line of thinking was much clearer now.

Lin Yuan was momentarily at a loss about how to respond to the Source Sand.

Lin Yuan looked around him. There were thousands of mobile castles that were hundreds of meters tall and gliding swiftly through the sand.
