After composing himself, Xiao Yifeng gently stroked the Immortal-Slaying Sword in his hand. A thousand years ago, the sword had only possessed a sliver of spirituality, but through endless slaughter, it had absorbed countless souls. Over the millennium, it had long since birthed a sword spirit, though it was still young and weak.

In his previous life, Xiao Yifeng had only learned later from the Immortal-Slaying Sword itself that she had already birthed a sword spirit over three hundred years ago. However, because the sword had acknowledged Mo Tianqing as its master, it was unable to escape his control. Otherwise, it would have devoured Mo Tianqing's soul long ago.

The Immortal-Slaying Sword was an ominous, master-devouring sword. From its birth to this day, that had never changed.

Due to the sword spirit's rejection and the sword's inherent ability to harm spirit bodies, even though Mo Tianqing was its master, he couldn't use Soul Possession to wield the Immortal-Slaying Sword and leave the Heaven-Inquiry Sect.
