It wasn't until the evening of the third day that someone knocked on his door.
Before he could move to open it, the door, also made of mithril, silently swung open, and a female wraith walked in from outside.
The moment he saw the female wraith, Long Dangdang's spine tensed instantly, and he almost lashed out in the next moment. He recognized this wraith. Yes, one of the very few wraiths he knew.
Back in the Holy City, it was this one who attacked him and Kongkong! They almost got killed by her. At that time, her cultivation was at the peak of the 7th Rank, and her formidable strength left a very deep impression on Long Dangdang.
But now, the aura emanating from her was far beyond that of Peak 7th Rank, even touching the threshold of the 9th Rank. The immense wraith energy seemed even more vigorous amid the rich element fluctuations within the Mithril Castle.
