After making her decision, she immediately unsealed herself and fully activated the Satan bloodline in her body. She cultivated crazily as she struggled with the demonic will. In just two days, she raised her cultivation to the peak of the ninth level.
In fact, Satan's decision for Mika to replace him was not because he had no other choice. Satan already had this notion when Mika was still in the Dark Citadel.
Mika was extremely talented, far more talented than her sister. She was even more talented than Satan himself when he was young. Later, she escaped from the Dark Citadel and sealed Satan's bloodline with Lan Jue's help. Even so, her strength continued to increase. She broke through to the ninth level and even reached the ninth level sixth rank.
