Chapter 663: Nitrox

'Is that an Undead Beast King, the Nine-armored Land Drake?' Xia Fei's eyes sparkled as he muttered to himself.

The Nine-armored Land Drake was a level 9 Beast King. It was an undead, so despite its fairly majestic appearance at the moment, it was actually a living corpse.

Different from other types of exotic beasts, the Nine-armored Land Drake had a nucleus that was formed by absorbing Cosmic Origin Energy. It was called the Beast Spirit Core. The Beast Spirit Codex had mentioned this, but while exotics beasts had a Beast Spirit Fire, undead exotic beasts would actually ossify this Beast Spirit Fire into a shiny crystal core.

As long as the crystal core remained intact, no one would be able to kill it. Flesh which got chopped off could regrow, and it was the same for its internal organs. Unless that Beast Spirit Core got shattered, the creature could just keep coming back to life.
