Chapter 38. Dare To Lay Even A Finger On Him and I Will Wipe Out Your Entire Race 

Demon beasts were half-demon and half-beast. They were vicious creatures who could eat anything but they liked flesh and blood as a result of their demonic nature. Though they were the beings who used to feed on the cultivated energy of high-ranked cultivators but because they couldn't find any high-ranked cultivators in the Lost Souls Realm therefore they learned to eat anything that came in their way. 

Unfortunately, when Vismay and Nishank started dueling they emitted so much cultivated energy that it attracted the Demon-Beasts who rushed toward the source of the alluring energy. The Demon-Beasts couldn't resist the delicious and strong spiritual energy that was spreading in the entire forest.
