Zang Xiaojian took a slight breath.
The imposing force of heaven and earth enveloping her flying sword was the so-called Sword Intent.
Although it was only the weakest level of Sword Intent, as a supreme technique that could be mastered only by high-level cultivators, even an extremely tiny wisp carried an awe-inspiring might.
Under the enhancement of the Wind Sword Intent, her flying sword not only broke through the sound barrier but also, carrying the imposing force of heaven and earth, pierced straight into the unprotected belly of the Black Jiao and slashed its demon core.
Of course, wielding Sword Intent with her Foundation Establishment Cultivation placed an enormous strain on her.
Just that one stroke depleted forty percent of Zang Xiaojian's spiritual power, which was why she would not resort to this Sword Intent unless absolutely necessary.
