It flashed through the air in an instant, already entering the battle fray.
A sword produced substance from nothingness; clearly nothing was seen, but as the sword light appeared, it had already pierced into Zhou Ping'an's shoulder.
If not for the final moment when Zhou Ping'an slightly shifted his form, he would have been pierced through the heart.
This sword strike was both fast and hidden, coming without a trace, leaving without a shadow, so much so that even Green Lady didn't know where to begin to warn him.
From this, it could be seen that although Saintess Yunling was raised delicately and her Sword Intent might not be the strongest, her understanding and depth in swordsmanship were still above Lady of the Wind and Thunder Sword Guard.
One could say she "surpassed her master."
"It's the perfect time," she murmured.
