It was fast.
The sword, reaching its extreme speed, crossed a distance of three zhangs with scattered blades, slicing the Wujin beast in half before Zhang Yunji's body, its wide mouth open.
Due to its speed, the bisected Wujin beast still had a fierce and triumphant glint in its eyes.
"Boom!"
The sword light cleaved the black gold beast's 10-foot-long body and reached down another 100 feet, completely splitting the muddy marsh.
Within the marsh, a dark golden light flashed, only to be covered again by surging mud.
"Pa!"
Two pieces of the black gold beast's body fell to the ground, and two black fist-sized black gold bricks rolled to the ground. The cracks on the black gold bricks could be seen clearly.
The extraordinarily tough black gold stone, which required secret methods to refine, was severed with a single sword.
The power of this sword was terrifying.
