From the initial formation of the Sword Wheel, it appeared somewhat illusory, as if it wasn't perfectly formed. As time passed, it gradually solidified, becoming stronger and fiercer.
Moreover, between the cycles of the Sword Wheel, the changes between offense and defense were unpredictable, and the attacks became increasingly tricky. At a certain moment, he sensed a touch of deadly intent from a flash of swords.
Yet his fierce attack was blocked by another flash of swords; an endless, relentless show of defense. Just when he thought it was merely a defensive sword, it transformed into a sword of death in an instant.
He narrowly avoided losing his arm to a slash!
As the battle ensued, Xu Yan's understanding deepened. The Life and Death Sword Wheel kept improving until it was spinning like the Taiji symbol in front of him.
The sword light slowly morphed into black and white, with continuous transformations, as if a new Sword Intent was being born.
