After much contemplation, Xuanqing didn't immediately seek out Minghe, instead delving into the research of the "Nine Grade Merit Golden Lotus" and the flesh and bones of Taotie...
For, he discovered that the method by which the Golden Lotus Seed absorbs merit to grow, and the Swallowing Great Dao within Taotie's bloodline, could be said to share a wonderfully similar ingenious principle!
After tens of thousands of years of research, he did indeed master some techniques, allowing him to forcibly devour and merge two similar origins with the aid of merit.
For this, he specifically allowed his Fire Dao incarnation, "Sui Ren," to ask Hao Tian for a long leave under the pretext of seclusion, and then quietly came to Golden Turtle Island.
