If Bai Ling's current power is based on her understanding of power in her previous life, it should already be at the fourth level.

Thinking of this, Bai Ling was not in a hurry. Two third-level wood-type crystal nuclei will allow her uncle to be promoted to third-level, and then the fourth-level wood-type crystal nucleus could be eaten again, and he would be promoted to fourth-level.

If it was possible, Bai Ling wished the mutant dog could eat Chen Xin too.

It's just that when Bai Ling saw the direction in which the mutant dog was running away, Bai Ling completely abandoned this idea. You must know that the third-order mutant dog has very sensitive senses, so it must also want to be promoted and come back, so it will naturally follow those with supernatural powers. 

The crystal nucleus of a junior zombie will definitely not be able to meet its needs for rapid promotion.
