Sword Storm Technique!
This was a technique originally created by Xu Ping'an during Ling Qingyao's time, and Xu Ping'an had once given guidance on it as well.
Therefore, in Shangguan Lingyu's eyes, even if Xu Ping'an had received the inheritance from that person, he should not be able to execute this move.
After all, this move was created by her master and with the status of that person, it should not be possible to pass on a disciple's technique to someone else.
At this moment, endless sword threads formed a hurricane behind Shangguan Lingyu, from which an unparalleled and terrifying aura emanated.
This sword had nearly depleted all of Shangguan Lingyu's True Yuan.
One could imagine just how terrifying the power of this sword was.
Xu Ping'an's expression also became solemn, as he felt a tremendous threatening aura from this sword.
A slight misstep, and he might also suffer a disastrous defeat.
