Making preparations in case he needed to leave, he turned back to look at Mingyu.
"I'm sorry, but I have to send you to the Fake World, for now, to keep you safe and to make sure things go smoothly. Alright?" He asked.
To his question, Mingyu nodded lightly. Since he said it was necessary, it must be. In any case, it was implying that he might need to leave to escape if it was a strong enemy. If that weren't the plan, he wouldn't have sent her to fake world instead of letting her stay safe beside her father.
So she realized what he was trying to do. In any case, she had already decided that if he wanted to leave, she was ready. The war was over. And his parents were safe. She didn't need to worry about them anymore.
"Wait, what are you saying? Where are you sending my daughter?" The Emperor asked, hearing his words. He knew that it was the day Long Chen died, and he had to keep his daughter as far away from him as possible.
