Chapter 688: Sky-fire Territory

"Slash!"

Su Mo waved his long sword, which instantly sent out dazzling three-colored sword radiance.

The sword Qi emanated terrifying sword power that was strong enough to destroy the world.

The air in its path was torn to pieces, and the three-colored sword Qi hurtled toward Sikong Yan with unparalleled speed.

Immediately after this move, Su Mo followed swiftly behind the sword Qi and dashed forward.

"What?"

Sikong Yan's expression changed to disbelief when he saw the power of Su Mo's move.

This slash was many times stronger than Su Mo's previous moves, and Su Mo's aura also contained eruptive power like a volcano.

Su Mo's strength startled everyone.

"What's going on?"

"How did Su Mo's strength suddenly soar?"

"What terrifying aura. What kind of secret skill is he using? It's so amazing!"

Everyone was shocked by Su Mo's aura, which clearly exceeded Sikong Yan's.

No one could accept this sudden shift.
