The scarlet-gold light seal whistled through the air, carrying waves of heat as it came straight at Yue Shan.
"This fluctuation..."
Yue Shan's expression turned grave, because he could tell that Mu Zi's attack was enough to threaten a Great Perfection expert.
In their previous exchanges, although Mu Zi had successfully tied him down, she had always been forced onto the defensive and had struggled to pose much of a threat to him.
But now that Mu Zi had unleashed the "Heavenly Yuan Seal," Yue Shan finally treated her as a true opponent.
Still, though Mu Zi's attack was enough to make him take it seriously, it was not enough to make him fear it.
"Mountain Fist!"
Yue Shan went all out, once again unleashing his strongest martial art. The Yuan Power fist seal tore through the air and slammed head-on into the scarlet-gold light seal.
"Boom!"
The instant they collided, violent energy fluctuations erupted. Scorching heat and heavy fist intent clashed fiercely between the two of them.
Wave after wave of powerful shockwaves spread from the point where the two attacks met, pressing the ground below into a pit.
"A mere Heavenly Yuan Realm dares act so wildly? Break for me!"
Yue Shan let out a furious shout, Yuan Power surging out from within his body. In an instant, a powerful radiance erupted from the fist seal, and its might increased greatly.
The scarlet-gold light seal immediately fell into a disadvantage, forced back again and again by Yue Shan's offensive.
Yue Shan erupted with power. The huge fist seal in midair inched closer to Mu Zi, and as the two attacks moved, the powerful impact generated at the center of the collision plowed a deep trench through the ground.
"Hahaha, you'll pay the price for your arrogance!" Yue Shan
