Su Mo was engaged in a heated battle against the giant demon in the Cursed Dark Demon Formation.
After activating the Three Secret Techniques, he had gained the upper hand and overpowered the giant demon.
However, it suddenly became much stronger in just a short while and turned the tide of the battle. It was equally powerful as Su Mo now.
"What's going on?" Su Mo fell back rapidly with his face black.
"This giant demon is created by the formation's power so its strength should be fixed. How did it get so much stronger in such a short time?"
"Is someone controlling the formation?" Su Mo made a guess. If there was no one controlling the formation, the demon could not have gotten stronger.
Su Mo realized that it might be the expert of Netherworld Devil Sect who was controlling the formation.
Rumble!
The giant demon charged toward Su Mo and brandished its bone spike like a huge bat to attack Su Mo's head.
