"Where is this place?" Scarlet Heaven Sword asked. How did Song Shuhang even know this place?
Song Shuhang's primordial soul floated in the sky, looking over the castle built on the mountain, and whispered, "This is the home of Black Pupil XIII."
When it came to karmic ties in the Black Dragon World, the only ones with whom he had relatively deep ties were Lady Kunna and Black Pupil XIII.
The former was due to them being allies plus the Will of the Dragon Network and her having something to do with the fat ball, while the latter was an existence that Song Shuhang had once lived as in the dreamland, though he did only live the younger years of his life.
During that dreamland, Song Shuhang had gotten a complete 'Black Dragon World language pack' and a complete meditation technique from the other party.
