The crystal cores raised ordinary humans to awakened users, but the probability was extremely small. Prior to this, the individual needed to be extremely healthy; otherwise, he or she would not be able to bear the violent pains from the transformation.
Qin Jiaojiao's body had always been weak, and Qin Yi had recalled her many failures. Searching far and wide, she heard a rumor that such a state could only wield healing abilities.
Healing abilities were extremely rare in the apocalypse. A probability of 1 out of a few thousand was already considered good.
That was considerably better than finding a healing type zombie, but Qin Yi still ultimately sourced for one. Qin Yi survived a narrow escape for the sake of the crystal core, which resulted in Qin Jiaojiao awakening with the healing abilities and being hailed by others as a goddess, gaining popularity and admiration.
