"Demon King, you're here too." Ling Chuxi didn't notice the deep smile hidden behind clan leader Ling's smile and saluted the old demon Emperor with the etiquette of a junior.
"Miss Ling doesn't need to be so polite. You're also a Grandmaster now, so we should address each other as equals." The old demon Emperor said courteously.
"We will need your help to repair the ancient formation." Ling Chuxi said.
"This concerns the safety of the entire human world. The demonic beasts of the little silver ancient mountain are obliged to do so." The old demon Emperor nodded his head and said righteously. However, he changed the topic and said,"when I came, clan leader Ling had already told me about repairing the ancient formation. However, my demon Emperor bloodline awakened too late and the power of the five elements is not pure. I'm afraid it's difficult for me to take on this important task."
