Meanwhile, Su Yu's figure flashed, and he moved swiftly out of the sword formation.
An indiscernible black silhouette also followed Su Yu, in an attempt to leave the sword formation.
However, just as the black shadow flickered, the sword formation abruptly began to operate. A sharp blade of silver sword lacerated the black shadow and forced it back.
Upon leaving the sword formation, Su Yu looked back but could not see any trace of the killer.
To be precise, Su Yu could clearly feel that the black shadow was indeed amidst the sword formation, but when Su Yu's eyes fell upon her, his gaze was always shifted away by force.
"Could this be her Divine Path?" Su Yu asked himself.
Inside the sword formation, the black shadow flickered continuously as it strove to leave the sword formation, only to find that this sword formation was a very well-built one, and there were no flaws that would allow one to leave.
