Jerald took it easy on Shang. After all, Jerald was far more powerful than him.
For now, Jerald decided to emulate a normal Mid High Mage. He simply slowed his movements and used less Mana for his Spells.
Sure enough, Shang had shown incredible power. In fact, Jerald had to do his best not to increase his power by more since Shang kept pushing him back at frightening speeds.
The new techniques Shang had come up with in the last 50 years were especially terrifying. Just the fact that Shang had created such an effective technique against Mages in his Colossal Sword State was impressive.
Jerald also felt the power of Shang's attacks on his Mana Shield.
Initially, it wasn't anything too special, but as Shang entered his Great Sword State, the power ramped up significantly!
And when Shang entered his Saber State, the fight had completely changed yet again.
But the most terrifying state was the Long Sword State. At least for Mages.
