The Evil Eye Lord was insidious and cunning to the extreme, ranked sixth among the Ten Great Fierce Beasts. Shen Lang had no intention of wasting time negotiating with it, so he got straight to the point.
The more intelligent a creature like this was, the better it understood its own predicament—and the more it feared death.
Demon Beasts were naturally malevolent and vicious. Many didn't even fear death... or perhaps didn't even understand what death was.
But a mutated, evolved Demon Beast like the Evil Eye Lord possessed a high degree of Spiritual Wisdom. It lacked the frenzied aura typical of most Demon Beasts, displaying more human-like traits instead.
He would weigh the pros and cons, he would fear death, and he would experience many emotions typically only found in humans.
If any other Demon Beast had been trapped by Shen Lang, it would have undoubtedly roared and thrashed about, trying to charge its way out.
