As these unknown changes unfolded within Yun Xiao's body, what he didn't realize was that the Strange Spirit not far from him also underwent some hidden transformations.
The fresh blood that Yun Xiao had spat onto the face of the Strange Spirit had been completely absorbed by it during this time. It seemed as if the nonexistent gaze of the Strange Spirit suddenly shifted towards the lean young man.
If the Strange Spirit had eyes, ears, mouth, and nose, it would probably lick its tongues at this moment, as Yun Xiao's blood was too delicious for it. After absorbing that blood, it felt a bit light-headed.
The Strange Spirit had considerable Spiritual Wisdom, not as high as that of a Vein Demon or a human, but it was clear it had noticed something was off about Yun Xiao's actions.
