Wang Tao first looked at the items that the zombie Wu Fei had dropped.
The Crystal Core inside Wu Fei's head was an Ascension Crystal Core!
However, because Wu Fei had only recently turned into a zombie, the core was a deep green color.
[Level 2 Crystal Core - Ascension]
[Quality: Rare (55%)]
[Purity: 45% (Side effects: None)]
Wang Tao had now spotted a pattern: for Level 2 Zombies with several abilities, the Crystal Core in their heads was likely to be one of their abilities plus either the Ascension or the Omnipotent Crystal Core.
That meant, if a Level 2 Zombie possessed four abilities, then the Crystal Core it dropped could be one of those abilities or it could be either an Ascension or Omnipotent Crystal Core.
Each kill would drop only one Crystal Core, and the probability for each type of core was probably one in six.
