Moreover, the essence of a resurrected undead was not that of a real undead. The former could absorb death energy at the speed of a tortoise. Only purebred undead could absorb death energy in large quantities and transform it.
Shen Yanxiao seemed to have yet to reach adulthood; she was in fact even younger than many of the students of Deathfire Academy. The dean believed that his judgment was correct. The little fellow in front of him was definitely a purebred undead. Based on the absorption speed of a purebred undead, if Shen Yanxiao had been absorbing death energy all this time, it would not be difficult for her to achieve this breakthrough.
The advancement of purebred undeads was much faster. It took dozens of years for a resurrected undead to advance, and on the other hand, it would only take a few years for a purebred undead to advance.
