While waiting for her mother to finish cooking, Bai Meiyue locked herself in her room and started cultivating again. She held the zombie nuclei that she had picked up in her hands and concentrated hard to absorb their essence. In her past life, she had a hard time while learning how to absorb these nuclei.
No one wanted to see another supernatural getting ahead of them. Thus, she never found a teacher who would teach her how to use these nuclei.
Back then, Bai Meiyue was in such a desperate situation that she actually ate these nuclei after washing off the splattered chunks of brain sticking to it. Even though it was disgusting, she did not want to die. So, she could only grit her teeth and do everything possible to stay alive.
Fortunately, she was a quick learner. Thus, after watching a few supernatural beings absorb these nuclei, Bai Meiyue also learnt how to absorb them.
