Jin Yu's complexion changed slightly as he watched the astonishing Sword Qi and already felt its incredibly sharp essence.
"Guardian Spell!"
Jin Yu left traces in the air as he inscribed one Dharma Seal after another, and his three Shikigami also employed the Guardian Spell.
It was as if four mighty beings had cast the Guardian Spell at the same time, creating an extremely solid defensive formation that floated in mid-air, blocking the path of Bu Fengning's Sword Qi.
As the astonishing Sword Qi struck the solid defensive wall, the wall immediately began to vibrate violently. The intense shaking surprised everyone present, especially Jin Yu on the arena, who could clearly feel that just this single Sword Qi from Bu Fengning was already reaching the critical point that the defensive wall could withstand!
"How can it be so strong!?"
