章節 1142: Sea Domain Origin

"Haha, it seems Xue Ying has gained quite a lot in his trip to the Realm Heart God Palace. For him to persist in there for more than 100 million years and to be this strong, is it because he has found a top-graded secret treasure?" Southern Cloud King shook his head with a smile, "This disciple of mine seems more fortunate than his teacher, I! Thinking back to the past, how much effort did I put in just to get my top-graded secret treasure?"

In order to get the top-graded secret treasure, 'Twin Realm Blade', Southern Cloud King was forced to swear an oath. Furthermore, this 'teacher' of his, the Undying Underworld Emperor, who was an ancient existence that existed before the First War of the Ancient Nations, actually came back alive.

Otherwise, given the strength of the Southern Cloud King, it was impossible for Undying Underworld Emperor to do anything to him even if he chose to disobey the oath.
