Calamity Spirit.
Just as its name suggested, it was a terrifying vengeful spirit formed from the combination of a Spiritual Body and the hidden malevolence and resentful thoughts within the Yellow Springs Abyss.
Even with Jian Ding's sharpness, it couldn't fully pierce through it.
This was precisely why Shenzhu Shihui suggested taking a step back to assess the situation.
But the above only applied to the Calamity Spirit in its complete state!
It must be known that Beichuan Si had forcibly extracted it from a bundling of resentful thoughts.
That is to say, the Calamity Spirit before them was not in its complete state.
If one looked closely, they would see that its lower half was oozing pungent, yellowish putrid liquid.
This was also the reason why Beichuan Si did not hesitate to draw Jian Ding!
If the Calamity Spirit regained its strength, the situation would only become more difficult to resolve.
