Beast Slayer
Blood Centipede.
Khal was able to remember this type of Beast quite well as he already read about it from the book he obtained from the old lady.
And what could he say... Blood Centipedes were creatures not only with chilling and powerful powers but their Cultivation Strength was strong too!
They were Beasts on the Fifth Stage and on its Peak to top it off! Blood Centipedes had a small centipede-like appearance, but with the sole difference that they had small mouths filled with tiny razor-sharp teeth in each of their feet, helping them to bury themselves into their prey and suck their blood away from their body from the inside.
Imagining the sensation as his blood was sucked away from the inside in a blink made Khal feel a slight chill run through his spine, all his hair on his body standing on end!
