As Soon as I Wear It Quickly, I Encounter the Big Devil

I met the Great Demon King just after traveling through time. What was even more frightening was to see with my own eyes a crazy smile on the lips of the Great Demon King, murdering most of the world in a sinister manner! She was so frightened that she couldn't choose her way out. Unexpectedly, the murderous devil turned around and saw her. Suddenly, his smile froze and he walked towards her through the blood mist. She thought she had to die at first, but unexpectedly he accepted her as his apprentice. Many years later, he walked towards her with red eyes and an evil spirit. He touched her face with trembling hands and said in an unusually gentle tone: "Disciple, where have you been? I have been looking for you for a long time."
